RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.

The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Small double-stranded, non-protein coding RNAs (21-31 nucleotides) involved in GENE SILENCING functions, especially RNA INTERFERENCE (RNAi). Endogenously, siRNAs are generated from dsRNAs (RNA, DOUBLE-STRANDED) by the same ribonuclease, Dicer, that generates miRNAs (MICRORNAS). The perfect match of the siRNAs' antisense strand to their target RNAs mediates RNAi by siRNA-guided RNA cleavage. siRNAs fall into different classes including trans-acting siRNA (tasiRNA), repeat-associated RNA (rasiRNA), small-scan RNA (scnRNA), and Piwi protein-interacting RNA (piRNA) and have different specific gene silencing functions.
Variation in a population's DNA sequence that is detected by determining alterations in the conformation of denatured DNA fragments. Denatured DNA fragments are allowed to renature under conditions that prevent the formation of double-stranded DNA and allow secondary structure to form in single stranded fragments. These fragments are then run through polyacrylamide gels to detect variations in the secondary structure that is manifested as an alteration in migration through the gels.

Overexpression of fibroblast growth factor receptor 3 in a human thyroid carcinoma cell line results in overgrowth of the confluent cultures. (1/1566)

Recent reports indicate that a gain-of-function mutation in fibroblast growth factor receptor 3 (FGFR-3) inhibits cell growth in the cartilaginous growth plates. These results suggest that FGFR-3 may be the receptor transducing growth inhibitory signals. Using reverse transcription-PCR we examined seven papillary thyroid carcinomas to determine FGFR-3 expression. Six out of the seven papillary carcinomas expressed FGFR-3. To clarify the role of FGFR-3 in thyroid carcinoma, FGFR-3 was overexpressed in an established human papillary thyroid carcinoma cell line. High levels of FGFR-3 protein were identified in cells stably transfected with the vector containing FGFR-3 cDNA. The specific binding of 125I-FGF-2 of these cells was threefold higher than that of control cells. Growth rates of cells overexpressing FGFR-3 were similar to those of control cells. However, cells overexpressing FGFR-3 continued to grow beyond the density at which control cells stopped proliferating. These results suggest that FGFR-3 in thyroid carcinoma is not involved strongly in the cell proliferation mechanism but may contribute to the malignant extension of some of the carcinomas by modifying cell contact signaling.  (+info)

Frequent genetic alterations in simple urothelial hyperplasias of the bladder in patients with papillary urothelial carcinoma. (2/1566)

In order to understand the origin of bladder cancer, very early urothelial lesions must be investigated in addition to more advanced tumors. Tissue from 31 biopsies of 12 patients with urothelial hyperplasias and simultaneous or consecutive superficial papillary tumors were used to microdissect urothelium from 15- microm sections of biopsies. The biopsies were obtained with the recently developed highly sensitive diagnostic method of 5-aminolevulinic acid-induced fluorescence endoscopy (AFE). Besides flat and papillary urothelial neoplasms, the method of photodynamic diagnostics also detects simple urothelial hyperplasias as fluorescent positive lesions. In addition, 12 fluorescence-positive biopsies showing histologically normal urothelium were investigated. Fluorescence in situ hybridization was done using a dual color staining technique of biotinylated centromeric probes of chromosomes 9 and 17 and digoxigenin-labeled gene-specific P1 probes for chromosomes 9q22 (FACC), 9p21(p16/CDKI2), and 17p13(p53). Ten of 14 hyperplasias (70%) showed deletions of chromosome 9. In 7 out of 8 patients with genetic alterations in the hyperplasias the genetic change was also present in the papillary tumor. Six out of 12 samples of microdissected normal urothelium also showed genetic alterations on chromosome 9. Microdissection of urothelial lesions, obtained during AFE, has led to the first unequivocal documentation of genetic changes in urothelial lesions diagnosed as normal in histopathology. Thus, this technical approach is important to provide insight into the earliest molecular alterations in bladder carcinogenesis.  (+info)

A new rapid technique for the fixation of thyroid gland surgical specimens. (3/1566)

One of the main diagnostic problems in thyroid pathology is to distinguish between follicular adenoma and follicular carcinoma. Thorough sampling of the nodule's capsule is recommended in order to identify capsular invasion. However, during the hardening of the tissue, by the usual fixatives the capsule shrinks and rolls downwards and sometimes the capsule separates from the remaining tissue. The present work evaluates the use of "Lymph Node Revealing Solution" (LNRS) for the rapid fixation (2h) of different thyroid lesions as compared to that of formalin. Fifty-one unselected consecutive cases of thyroid nodules, which included various benign and malignant lesions, were examined. Each specimen was cut in two equal parts; one was fixed in LNRS, the other in formalin. Fixation in LNRS for 2 hours gave adequate results in sectioning and staining of the tissue, and excellent immunostains. Its advantage over formalin is the conservation of the natural relationship between the capsule and the rest of the tissue, on the same plane, as well as the short time required for the final diagnosis.  (+info)

Human thyroid cancer cells as a source of iso-genic, iso-phenotypic cell lines with or without functional p53. (4/1566)

Differentiated thyroid carcinomas (in contrast to the rarer anaplastic form) are unusual among human cancers in displaying a remarkably low frequency of p53 mutation and appear to retain wild-type (wt) p53 function as assessed by the response of derived cell lines to DNA damage. Using one such cell line, K1, we have tested the effect of experimental abrogation of p53 function by generating matched sub-clones stably expressing either a neo control gene, a dominant-negative mutant p53 (143ala) or human papilloma virus protein HPV16 E6. Loss of p53 function in the latter two groups was confirmed by abolition of p53-dependent 'stress' responses including induction of the cyclin/CDK inhibitor p21WAF1 and G1/S arrest following DNA-damage. In contrast, no change was detected in the phenotype of 'unstressed' clones, with respect to any of the following parameters: proliferation rate in monolayer, serum-dependence for proliferation or survival, tumorigenicity, cellular morphology, or tissue-specific differentiation markers. The K1 line therefore represents a 'neutral' background with respect to p53 function, permitting the derivation of functionally p53 + or - clones which are not only iso-genic but also iso-phenotypic. Such a panel should be an ideal tool with which to test the p53-dependence of cellular stress responses, particularly the sensitivity to potential therapeutic agents, free from the confounding additional phenotypic differences which usually accompany loss of p53 function. The results also further support the hypothesis that p53 mutation alone is not sufficient to drive progression of thyroid cancer to the aggressive anaplastic form.  (+info)

Tissue inhibitor of metalloproteinases-1 (TIMP-1) mRNA is elevated in advanced stages of thyroid carcinoma. (5/1566)

Tumour cell invasion and metastasis is a multistep process that involves the degradation of extracellular matrix proteins by matrix metalloproteinases (MMPs). Tissue inhibitors of metalloproteinases (TIMPs) act as negative regulators of MMPs and thus prevent tumour cell invasion and metastasis by preserving extracellular matrix (ECM) integrity. In the present study we examined the expression of one member of TIMPs, TIMP-1, in 39 thyroid tumour specimens and two thyroid carcinoma cell lines (NPA and SW579). We also investigated the effect of high TIMP-1 expression on the invasive potential of NPA cells. Northern blot analysis showed that TIMP-1 mRNA levels correlated directly with tumour aggressiveness: the highest number of TIMP-1 transcripts was found in stages III and IV vs benign goitre (P < 0.0001). However, TIMP-1 expression was not increased in NPA and SW579 cells, both of which are derived from poorly differentiated thyroid tumours. Immunohistochemical study showed strong TIMP-1 staining in the stroma cells of advanced stages of carcinomas. Overexpression of TIMP-1 by gene transfer resulted in a significant suppression of the malignant phenotype of NPA cells as judged by an in vitro tumour invasion assay. These results suggest that high levels of TIMP-1 transcripts in advanced stages of thyroid carcinoma likely come from stroma rather than thyroid cancer cells, and TIMP-1 may function as a thyroid tumour invasion/metastasis suppressor.  (+info)

Elevated reticulocyte count--a clue to the diagnosis of haemolytic-uraemic syndrome (HUS) associated with gemcitabine therapy for metastatic duodenal papillary carcinoma: a case report. (6/1566)

In adults, the haemolytic-uraemic syndrome (HUS) is associated with probable causative factors in the minority of all cases. Cytotoxic drugs are one of these potential causative agents. Although metastatic cancer by itself is a recognized risk-factor for the development of HUS, therapy with mitomycin-C, with cis-platinum, and with bleomycin carries a significant, albeit extremely small, risk for the development of HUS, compared with all other cytotoxic drugs. Gemcitabine is a novel cytotoxic drug with promising activity against pancreatic adenocarcinoma. We are reporting on one patient with metastatic duodenal papillary carcinoma developing HUS while on weekly gemcitabine therapy. The presenting features in this patient were non-cardiac pulmonary oedema, renal failure, thrombocytopenia and haemolytic anaemia. The diagnosis of HUS was made on the day of admission of the patient to this institution. Upon aggressive therapy, including one single haemodialysis and five plasmaphereses, the patient recovered uneventfully, with modestly elevated creatinine-values as a remnant of the acute illness. Re-exposure to gemcitabine 6 months after the episode of HUS instituted for progressive carcinoma, thus far has not caused another episode of HUS.  (+info)

Induction of mammary carcinomas by N-methyl-N-nitrosourea in ovariectomized rats treated with epidermal growth factor. (7/1566)

The importance of epidermal growth factor (EGF) in both normal and malignant mammary gland development are presented in these studies. Initial findings demonstrated that in the absence of ovarian hormones, EGF had a significant proliferative effect on mammary epithelial cells. To determine whether mammary epithelial cells grown with EGF, in the absence of ovarian hormones, could be transformed by N-methyl-N-nitrosourea (MNU), female ovariectomized Lewis rats were implanted with pellets containing EGF for 1 week and then treated with MNU for initiation. Two days after MNU treatment, ovaries were implanted and EGF pellets were removed from all ovariectomized groups in order to promote carcinogenesis. The mammary carcinoma incidence of the EGF-stimulated group (90%) was not significantly different from the intact group (100%). The mammary cancer morphology of EGF-treated carcinomas was either ductal carcinoma or cribriform adenocarcinoma, whereas intact animals developed mainly papillary and occasional cribriform carcinomas. Fifty-eight percent of the carcinomas from the EGF group were ovarian hormone-independent compared with 10% of carcinomas from the intact group. These results demonstrate that EGF-induced proliferation during initiation with MNU was sufficient to induce the transformation of mammary carcinomas in the absence of ovarian hormones. The hormonal dependency of these EGF-induced carcinomas were different compared with MNU-initiated mammary carcinomas in intact rats.  (+info)

The genetic locus NRC-1 within chromosome 3p12 mediates tumor suppression in renal cell carcinoma independently of histological type, tumor microenvironment, and VHL mutation. (8/1566)

Human chromosome 3p cytogenetic abnormalities and loss of heterozygosity have been observed at high frequency in the nonpapillary form of sporadic renal cell carcinoma (RCC). The von Hippel-Lindau (VHL) gene has been identified as a tumor suppressor gene for RCC at 3p25, and functional studies as well as molecular genetic and cytogenetic analyses have suggested as many as two or three additional regions of 3p that could harbor tumor suppressor genes for sporadic RCC. We have previously functionally defined a novel genetic locus nonpapillary renal carcinoma-1 (NRC-1) within chromosome 3p12, distinct from the VHL gene, that mediates tumor suppression and rapid cell death of RCC cells in vivo. We now report the suppression of tumorigenicity of RCC cells in vivo after the transfer of a defined centric 3p fragment into different histological types of RCC. Results document the functional involvement of NRC-1 in not only different cell types of RCC (i.e., clear cell, mixed granular cell/clear cell, and sarcomatoid types) but also in papillary RCC, a less frequent histological type of RCC for which chromosome 3p LOH and genetic aberrations have only rarely been observed. We also report that the tumor suppression observed in functional genetic screens was independent of the microenvironment of the tumor, further supporting a role for NRC-1 as a more general mediator of in vivo growth control. Furthermore, this report demonstrates the first functional evidence for a VHL-independent pathway to tumorigenesis in the kidney via the genetic locus NRC-1.  (+info)

Y1 - 2008/9/1. N2 - BACKGROUND. Intracystic papillary carcinoma (IPC) is an uncommon breast neoplasm. To the authors knowledge there are limited data regarding its epidemiology and only small studies focusing on outcomes. By using a large, population-based database, this study aimed to identify specific characteristics of patients with IPC, investigate its natural history, and determine its long-term prognosis. METHODS. The California Cancer Registry (CCR), a population-based registry, was reviewed from the years 1988 through 2005. The data were analyzed with regard to patient sex, age at presentation, tumor stage, and overall survival. Cumulative relative actuarial survival was determined using a Berkson-Gage life table method. The CCR classifies IPC as either in situ (CIS) or invasive, as determined by the ...
Nuclear retinoid receptors (RARs) upon a ligand binding act as all-trans retinoic acid-inducible transcription factors interacting as conditional heterodimers with nuclear retinoid X (rexinoid) receptors (RXRs). The disruption of retinoic acid (RA) signalling pathways is believed to underlie the etiology of a number of malignancies. RAR and RXR ligands are known to play role in reprogramming several tumour cells, and thus the development of appropriate ligands with reduced teratogenic and other side effects are still highly required. In this study, we have investigated expression pattern of retinoid receptor subtypes (RARalpha, RARbeta, RARgamma) and retinoid X nuclear receptor subtypes (RXRalpha, RXRbeta, RXRgamma) in three different human organ malignancies, i) thyroid papillary carcinoma, ii) breast cancer, and iii) renal carcinoma.. ...
Papillary squamous cell carcinoma (PSCC) of the uterine cervix is difficult to diagnose due to its rarity and limited data regarding its clinical behavior. We attempted to assess the degree of stromal invasion using magnetic resonance imaging (MRI) and evaluate possible treatments for this lesion in view of its clinical behavior. We analyzed 28 cases of PSCC diagnosed on the colposcopic selective biopsies. We studied the rate of accuracy of diagnoses of the colposcopic selective biopsies compared with the final diagnoses, and compared the rate of stromal invasion between the MRI and pathological findings while focusing on surgical methods and the clinical prognosis. Of the 28 patients, only 12 exhibited true PSCC. The other 16 patients were ultimately diagnosed with SCC or adenosquamous carcinoma based on the finding of the surgical specimens and exhibited relatively poor prognoses. Among the 12 true PSCC cases, the rate of diagnostic accuracy of stromal invasion (with or without) was only 58% (7/12) on
It remains controversial whether patients with papillary thyroid microcarcinoma (PTMC) benefit from total thyroidectomy (TT) or thyroid lobectomy (TL). We aimed to investigate the impact of extent of surgery on the prognosis of patients with unilateral PTMC. Patients were obtained from the Surveillance, Epidemiology, and End Results database from 2004 to 2015. Cancer-specific survival (CSS) and overall survival (OS) were evaluated by Cox regression and Kaplan-Meier curves with propensity score matching. Of 31167 PTMC patients enrolled, 22.2% and 77.8% of which underwent TL and TT, respectively. Patients with TT were more likely to be younger, females, present tumors of multifocality, extrathyroidal extension, cervical lymph node metastasis (CLNM), distant metastasis, and receive radioactive iodine (RAI) compared with those receiving TL. The multivariate Cox regression model showed that TT was not associated with an improved CSS and OS compared with TL with hazard ratio (HR) and 95% confidence interval

Extrathyroidal extension was more frequent in DSV than in TCV and cPTC patients (p < 0.05); moreover, only DSV tumors had a higher rate of recurrent/persistent disease when compared to cPTC treated with the same protocol (total thyroidectomy followed by (131)I treatment) (p < 0.01). After initial treatment, 54.2% of TCV and 20.4% of DSV patients were classified at low risk, while at ongoing risk stratification, the excellent response (low risk) was higher for both TCV (77.8%) and DSV (50.0%) patients relative to initial stratification (both p < 0.01). Using ongoing risk classification, positive predictive value (PPV) for persistent/recurrent disease was higher relative to initial risk stratification for both TCV (PPV = 93.8 vs. 39.4%) and DSV (PPV = 63.0 vs. 34.9%), p < 0.05 for both.

Patient: Thyroid Cancer > Papillary Carcinoma > Tall Cell Patient Info: Currently in active treatment (initial surgery, receiving chemo rounds/radiation), Diagnosed: over 10 years ago, Female, Age: 66, Stage IV
The thyroid is the organ that has the greatest risk of malignant tumors among the endocrine tumors. The papillary carcinoma occupies 80% of the entire thyroid tumors. Immunohistochemical staining of galectin-3 has usually been used in differentiating papillary carcinoma and follicular carcinoma. The p53 gene of the cell cycle is a tumor suppressor gene acting in on the control points. The cyclin D1 genes in the cell cycle, involved in the implementation of G1 and S phase, plays an important role in the progression of thyroid tumors. This research compares and analyzes correlation between papillary carcinoma, follicular carcinoma, p53, cyclin D1 and galectin-3 gene expression patterns. In a total of 30 cases from papillary carcinoma, 21 cases from p53 (70%), 27 cases in galectin-3 (90%), and 26 cases in cyclin D1 (86.7%) showed positive rate. The galectin-3 staining investigated, showed a significant difference between a papillary carcinoma and a follicular carcinoma. Follicular carcinoma from 15 ...
TY - JOUR. T1 - Papillary carcinoma of the thyroid gland. AU - Baker, R. Robinson. AU - Hyland, J.. PY - 1985. Y1 - 1985. N2 - The results of this analysis have demonstrated that papillary carcinoma of the thyroid gland rarely causes the death of the patient. Bilateral subtotal lobectomies, partial lobectomies and probably total lobectomy combined with contralateral partial lobectomy should not be performed in the treatment of this disease. The incidence of local recurrence is higher after these procedures, and any subsequent operative procedure is complicated by scarring secondary to the initial procedure. Total lobectomy is the procedure of choice for patients with disease confined to one lobe on palpation. Total thyroidectomy should only be performed for palpable disease in both lobes. Excision of a grossly normal contralateral lobe solely to obtain microscopic tumor which rarely becomes clinically apparent is not worth the inherent risk of bilateral recurrent palsy of the nerve or permanent ...

In 2016, Saleh [59] from Egypt, performed heterotopic autotransplantation of fresh thyroid tissue for 20 patients who underwent TT (13 with simple MNG, 4 with Graves disease and 3 with toxic nodular goiter). Intraoperatively, 10-15 g of the healthiest looking non-nodular part of the excised gland was minced into 1-2 mm slices after stripping of its fibrous capsule. The tissue was then made into an emulsion of 20 mL lactated Ringers solution and injected through the rectus femoris muscle in 6-8 different directions using a specially designed wide bore needle. The final postoperative pathology reported a follicular variant of thyroid papillary carcinoma in 2 patients in whom preoperative pathology missed their diagnosis. The 2 patients had their graft excised and were excluded from the study. Follow-up of 18 patients was done to report the survival and function of the heterotopic transplanted thyroid tissue through 99mTc uptake at 2-month postoperatively and thyroid function tests (FT3, FT4, and ...

If you have had your surgery, you are on your road to recovery...for me, only one lobe had cancer, it was removed,the other lobe remained. No chemo was needed. The docs told me that I needed to have suppression therapy, they use Synthroid. They say-- that is because I still have one lobe left and there is a potential for cancer cells, suppressing the lobe will hopefully keep the cancer cells at bay for awhile. The other thing the docs are doing is keeping my TSH level low, ,1. Please keep your chin up, I wish you all the best with your health in the ...

I dont have an oncologist either, my endocrinologist specializes in treating thyroid cancer patients so I didnt see a need. You can talk to your endo about this, bring all the lab reports from your mamograms, sonograms and biopsy so he has something to look at. Your surgeon may also be very knowledgable about the questions you have, depending on his speciality.. I think if the breast cancer is metastic thyroid cancer they would have told you so, but best to ask to be certain.. Yes, I know what you mean, lucky to catch it early. I didnt know anything was wrong until I felt a swollen lymph node in my neck. Per doctors orders, I waited for a few months for it to go down, then spent another month waiting for the biopsy and found I had papillary. I had a TT and neck disection 2/11 and RAI 4/11. So far no recurrance, but well see. Theyre right when they say lucky, if I had ignored the lump, Id probably be dealing with a larger metastic spread than just a couple of nodes in my neck. The thing ...

Thyroid carcinoma seems to have generated a considerable number of misconceptions. About 20% of these tumors are pure papillary, about 10% pure follicular, about 50% mixed papillary and follicular, and about 5% (range, 2%-10%) are called medullary. However, the pure papillary carcinoma usually has a few follicular elements if enough histologic sections are made, and […]. ...

Mutation of the BRAF gene is common in thyroid cancer. Follicular variant of papillary thyroid carcinoma is a variant of papillary thyroid carcinoma that has created continuous diagnostic controversies among pathologists. The aims of this study are to (1) investigate whether follicular variant of papillary thyroid carcinoma has a different pattern of BRAF mutation than conventional papillary thyroid carcinoma in a large cohort of patients with typical features of follicular variant of papillary thyroid carcinoma and (2) to study the relationship of clinicopathological features of papillary thyroid carcinomas with BRAF mutation. Tissue blocks from 76 patients with diagnostic features of papillary thyroid carcinomas (40 with conventional type and 36 with follicular variant) were included in the study. From these, DNA was extracted and BRAF V600E mutations were detected by polymerase chain reaction followed by restriction enzyme digestion and sequencing of exon 15. Analysis of the data indicated ...
Solid pseudopapillary tumors are rare, with the majority of described cases originating in the pancreas. To date, there are only 10 documented reports of primary ovarian solid pseudopapillary tumors. Here, we describe the case of a 24-year-old woman who presented with worsening pelvic pain and dysmenorrhea. Workup demonstrated a right ovarian solid mass on ultrasound and an elevated serum LDH, which raised concerns for dysgerminoma due to her relatively young age. Therefore, she was taken to the operating room and underwent laparoscopic right salpingo-oophorectomy. On initial rapid frozen section, her ovarian cyst had a grossly hemorrhagic appearance with multiple hemosiderin deposits noted microscopically, which suggested a benign hemorrhagic cyst. However, the final pathology was reported as solid pseudopapillary tumor based on several defining histologic characteristics. Most importantly, immunostaining was positive for |i|β|/i|-catenin and negative for E-cadherin. This report presents a brief

A collision tumor involving a tracheal sarcomatoid carcinoma and a papillary thyroid carcinoma has never been reported in the literature. A 78-year-old female presented with a large neck mass and hoarseness. A fine needle aspiration demonstrated papillary thyroid carcinoma. Imaging revealed a right thyroid mass invading into the tracheal lumen with bulky ipsilateral lymphadenopathy. The patient underwent a total thyroidectomy, tracheal resection, and central and right neck dissections. Pathology demonstrated a tracheal sarcomatoid carcinoma invading the right thyroid, which had multifocal papillary thyroid carcinoma with central and lateral neck metastases. The patient subsequently received adjuvant chemoradiotherapy and radioactive iodine. We present a case of a tracheal sarcomatoid carcinoma colliding with a papillary thyroid cancer. Treatment modalities should address the most aggressive tumor, while being tailored to clinical picture, tumor histology, and patient preferences.
The study objective is to analyze the mutation profile of the tall cell variant (TCV) of papillary thyroid carcinoma (PTC). Materials and methods. The main inclusion criteria according to the WHO classification (2017) was PTC composed of at least 30 % of tall cells. Genetic examination was conducted using the FoundationOne CDx assay (USA) with median depth of coverage of |500x. This study included 5 patients (1 man and 4 women) with a mean age of 52.6 years (range: 48-56 years). The tumor size varied between 0.4 x 0.5 cm and 11.0 x 9.0 cm. All patients have undergone surgical treatment: hemithyroidectomy for patient No. 1 with a small tumor (pT1b); thyroidectomy for patient No. 2 (pT3b); extensive thyroidectomy with the removal of paratracheal tissue for patients No. 3, 4, and 5 (No. 3 - pT3bN0; No. 4 - pT3bN1b; No. 5 - pT3bN1b). Three out of the five patients also had adenomatous goiter. The mean follow-up time was 3.4 to 5.2 years. Results. Tumors in all patients were characterized by low mutational
A comprehensive analysis of MNG1, TCO1, fPTC, PTEN, TSHR, and TRKA in familial nonmedullary thyroid cancer: Confirmation of linkage to TCO1. About 5% of nonmedullary thyroid cancer is familial. These familial nonmedullary thyroid cancer cases are characterized by an earlier age of onset, more aggressive phenotype, and in some families a high propensity to benign thyroid disease. Little is known about the genes conferring predisposition to nonmedullary thyroid cancer. Three loci have been identified through genetic linkage: MNG1 on 14q32, TCO1 on 19p13.2, and fPTC on 1p21. In addition to these putative genes, a number of loci represent candidate familial nonmedullary thyroid cancer predisposition genes by virtue of their involvement in sporadic disease (TRKA), their role in benign disease (TSHR), and because they underlie syndromes with a risk of nonmedullary thyroid cancer (PTEN). To evaluate the roles of MNG1, TCO1, fPTC, PTEN, TSHR, and TRKA in familial nonmedullary thyroid cancer, we have ...

AU - Qiu, Suimin. AU - Venegas, Rose. AU - Wen, Julie. AU - Wang, Hui Qun. AU - Xie, Jingwu. PY - 2007/5/30. Y1 - 2007/5/30. N2 - Solid pseudopapillary tumor of pancreas (SPT) is a rare neoplasm that occurs most often in young females with the two distinct features, the solid-cystic gross appearance, and the solid-pseudopapillary microscopic pattern. It has been reported that almost all SPT tumors contain a mutation in the β-catenin gene; however, the histogenetic origin of this tumor remains largely a mystery. E-cadherin is a cell adhesion molecule that links to catenins to form cell adhesion junctions, which is associated with the cytoskeleton formation. In this study, we examined the expression of E-cadherin and β-catenin from SPT in an attempt to determine the molecular basis for the unusual ...

Methods: Immune complexity profiles were quantitatively evaluated by multiplex immunohistochemistry (mIHC) in archived tissue sections from 39 patients with PTC, and were assessed for correlations with aggressive histopathological features based on the presence of lymphovascular invasion and/or extrathyroidal extension, and BRAF V600E mutational status. Results: mIHC ...
Synchronous primary cancers are occasionally observed, but TTM is extremely rare; only about 100 cases have been reported in the English literature. Campbell et al. [7] proposed the concept of TTM, which can be distinguished from collision tumor based on following criteria: 1) more than one primary tumor; 2) the recipient tumor may be a true benign or malignant neoplasm; 3) the metastatic neoplasm is a true metastasis with established growth within the host tumor, not the result of contiguous growth (collision tumor) or tumor emboli; 4) primary tumors spreading into the lymphatic system in the setting of generalized lymphoreticular malignancy are excluded.. According to the seed and soil hypothesis [8] of cancer metastasis, interactions between cancer cells (seed) and specific organ microenvironments (soil) determine the outcome of metastasis. Renal cell carcinoma and meningioma are both highly vascularized tumors, and have high lipid and glycogen content, which can provide a fertile ...
Introduction. Solid pseudopapillary neoplasm (SPN) of the pancreas is rare, accounting for 2-3 % of primary pancreatic tumours (1). It was first described by Frantz in 1959 and has since then been referred to as: solid and cystic tumour, solid and papillary neoplasm, Frantzs tumour, papillary-cystic neoplasm and papillary epithelial neoplasm. It was finally defined by the World Health Organization (WHO) in 2000 as a solid pseudopapillary neoplasm of the pancreas (2). SPN is considered a low malignant potential neoplasm, due to its benign morphology and the fact that it rarely metastasizes (3). Even though pancreatic tumours generally have bad prognosis, SPN shows good prognosis, which makes the disease entity unique in this disease group. To predict malignant behavior of SPN, several morphological criteria are needed (angioinvasion, invasion to surrounding tissue or unequivocal perineural invasion) and if present, the tumour should be designated as solid pseudopapillary carcinoma (SPC) (4). We ...
Thyroid cancer, the commonest of endocrine malignancies, continues increasing in incidence being the 5th more prevalent cancer among women in the United States in 2012. Familial thyroid cancer has become a well-recognized, unique, clinical entity in patients with thyroid cancer originating from follicular cells, that is, nonmedullary thyroid carcinoma. Hereditary nonmedullary thyroid cancer may occur as a minor component of familial cancer syndromes (familial adenomatous polyposis, Gardners...
Objective: Describe a case of a patient diagnosed with papillary thyroid carcinoma by a retropharyngeal tumor..

Through a transcriptome microarray analysis, we have isolated Anterior gradient protein 2 (AGR2) as a gene up-regulated in papillary thyroid carcinoma (PTC). AGR2 is a disulfide isomerase over-expressed in several human carcinomas and recently linked to endoplasmic reticulum (ER) stress. Here, we analyzed the expression of AGR2 in PTC and its functional role. Expression of AGR2 was studied by immunohistochemistry and real time PCR in normal thyroids and in PTC samples. The function of AGR2 was studied by knockdown in PTC cells and by ectopic expression in non-transformed thyroid cells. The role of AGR2 in the ER stress was analyzed upon treatment of cells, expressing or not AGR2, with Bortezomib and analyzing by Western blot the expression levels of GADD153. PTC over-expressed AGR2 at mRNA and protein levels. Knockdown of AGR2 in PTC cells induced apoptosis and decreased migration and invasion. Ectopic expression of AGR2 in non-transformed human thyroid cells increased migration and invasion and
Solid pseudopapillary tumors (SPTs) are unusual neoplasms that mostly occur in the pancreas, and predominantly affect young women. As a low-grade malignant neoplasm of the exocrine pancreas, they occasionally metastasize, usually to the liver or peritoneum. It has been reported that ,1% of SPTs are primary extrapancreatic SPTs. In the present study, we present two rare, but conspicuous extrapancreatic SPTs. Both occurred in young women, and showed good prognoses following surgery. One was a recurrent SPT of the pancreas that metastasized to the ovary, and the other was a distinct primary neoplasm that arose in the retroperitoneal area. The pathological features of the two tumors, including solid and pseudopapillary growth patterns with pale or eosinophilic cytoplasm, were characteristic of SPTs of the pancreas. However, in the case of the metastatic ovarian tumor, focal necrosis and an increased nuclear-to-cytoplasmic ratio were observed. The presence of positive nuclear-cytoplasmic β-catenin, ...
Tumor invasiveness is directly related to the ability of tumor cells to migrate and invade surrounding tissues, usually degrading extracellular matrix. Despite significant progress in the knowledge about migration and invasion, there is much more to elucidate about their regulatory mechanisms, especially in cancer cells. MicroRNAs (miRs) were recently described as important regulators of migration. Differential expression of miRs in cancer is frequently associated with progression, invasion and metastasis. In papillary thyroid carcinoma (PTC), miR-146b-5p is highly expressed and positively correlated to the degree of malignancy. This study aimed to investigate the role of miR-146b-5p on the migratory and invasive behaviors of thyroid cells, using a non tumor rat thyroid follicular cell line (PCCl3) transfected with the miR-146b-5p genomic region, and two PTC cell lines (TPC-1 and BCPAP, bearing distinct oncogenic backgrounds), which express high levels of miR-146b-5p, after miR-146b inhibition by

Aims: Metastatic nodes on power Doppler sonography tend to demonstrate high intranodal resistance and abnormal distribution of vascularity within a node. However, in our experience metastatic nodes from papillary carcinoma of the thyroid frequently demonstrate low intranodal resistance and some do not demonstrate the presence of any abnormal vascularity within. We were therefore interested to document these features. Materials and Methods: The grey scale and power Doppler sonograms of 21 metastatic nodes from papillary carcinoma of the thyroid were evaluated. The intranodal distribution of vessels and the intranodal vascular resistance of vessels was assessed and compared with the reported features of metastatic nodes from other head and neck primaries. Results: A majority (17/20, 85%) of metastatic nodes from papillary carcinoma of the thyroid had a maximum resistance index (RI) and pulsatility index (PI) , 0.8 and 1.6, respectively. A majority of the nodes (16/21, 76%) demonstrated abnormal ...

Papillary thyroid cancer (PTC) is the most common tumor subtype of thyroid cancer. However, not all PTCs are responsive to current surgical and radioiodine treatment. The well-established clinical prognostic factors include tumor size, lymph node/distal metastasis, and extrathyroidal invasion. The RET/PTC-RAS-BRAF linear molecular signaling cascade is known to mediate PTC pathogenesis. However, whether presence of BRAF mutation, the most common genetic alteration in PTC, can affect PTC behavior and prognosis is controversial. MicroRNAs (miRNAs) have been labeled as promising molecular prognostic markers in several tumor types. Our recent studies demonstrated that microRNA-146b (miR-146b) deregulation is associated with PTC aggressiveness and prognosis. Here we summarize the current knowledge related to the functional roles, regulated target genes, and clinical applications of miR-146b in PTC and discuss how these studies provide insights into the key role of miR-146b as an oncogenic regulator promoting
BACKGROUND:This paper aimed to evaluate the expression of REGg and characterize its clinical significance in papillary thyroid carcinoma (PTC). MATERIAL AND METHODS:In total, 54 patients with PTC who underwent partial or total thyroidectomy and cervical node dissection for PTC from February 2009 to September 2011 were retrospectively reviewed. Thyroid specimens and metastatic lymph nodes from 54 patients and normal thyroid tissues obtained from 13 volunteers were collected and analyzed. Tumor size, T-stage, and lymph nodes metastasis were recorded based on surgical pathology. Immunohistochemical (IHC) technology was performed to analyze REGg protein expression level. Corrections between the expression of REGγ and the clinicopathological factors were analyzed. RESULTS:All the normal thyroid tissues were REGg-negative. REGγ was positive in 75.9% (41/54) of PTC tissues, of which 29 cases (29/42, 69.0%) were in T1-T2 stage and 12 cases (12/12,100%) were in T3-T4 stage. Positive REGγ was found in 21 cases

Yim JH , Kim WB , Kim EY , Kim WG , Kim TY , Ryu JS , Gong G , Hong SJ , Shong YK. J Clin Endocrinol Metab April, 2011. The primary treatment of locoregionally recurrent/persistent papillary thyroid cancer (PTC) is surgical removal by reoperation. This study evaluated the efficacy of the first reoperation for loco-regionally recurrent/persistent papillary thyroid carcinoma and the usefulness of stimulated TG for evaluating efficacy of reoperation. A retrospective observational cohort study was done in a tertiary referral hospital. A total of 83 patients, who underwent initial total thyroidectomy and nodal dissection with radioactive iodine remnant ablation, received reoperation for loco-regionally recurrent/persistent PTC and were included in this study. Stimulated TG levels were assessed before and after reoperation. We assessed biochemical remission (stimulated TG,1 ng/ml) after reoperation and evaluated second clinical recurrence-free survival rate according to stimulated TG value. There was ...
Micropapillary carcinoma (MPC) is a rare variant of carcinoma, and it is composed of small papillary neoplastic cell clusters lying within clear lacunar spaces that simulate lymphovascular channels. This tumor has been described in the several organs such as the breast, lung, urinary bladder and salivary gland and it is known to be frequently associated with a high incidence of lymphatic invasion and metastasis in lymph nodes, resulting in poor clinical outcome. We present here a case of MPC in the gall bladder, and this type of case has not been previously described. Histologically, the tumor was composed of micropapillary carcinoma with tight clusters of micropapillary aggregates in the background of tubular adenoma. Focal invasive micropapillary components were also noted in the submuscular connective tissue. A metastatic lesion in a regional lymph node also showed an entirely micropapillary pattern. ...
Nucleotides are increasingly recognized as non-redundant extracellular signals for chemotaxis, cell growth and cytokine release. Effects of extracellular nucleotides are mediated by P2 receptors, among which the P2X7 subtype is attracting increasing attention for its involvement in apoptosis, cell growth and cytokine release. Recent studies showed that P2X7 is overexpressed in chronic lymphocytic leukemia, breast and prostate cancer. The aim of the present study was to better understand the clinical significance of P2X7 receptor expression in normal and cancer human thyroid tissues. P2X7 receptor message and protein expression and functional activity were tested in two cell lines (FB1 and FB2) established from either anaplastic and papillary primary thyroid cancer and in several histological samples of human papillary cancer. We show here that human thyroid papillary carcinoma, whether of the classical or follicular variant, express the P2X7 receptor (P2X7R) to a much higher level than normal ...
Papillary thyroid cancer, which is the most common type of thyroid cancer, makes up about 80% of all cases of thyroid cancer. It is one of the fastest growing cancer types with over 20,000 new cases a year. In fact, it is the 8th most common cancer among women overall and the most common cancer in women younger than 25. Although a person can get papillary thyroid cancer at any age, most patients will present before the age of 40.
Results-On VTI elastography: score 1 was found in 84 nodules (all benign); score 2 in 37 nodules (3 papillary carcinomas and 34 benign nodules); score 3 in 25 nodules (1 medullary carcinoma, 6 papillary carcinomas, and 18 benign nodules); score 4 in 53 nodules (50 papillary carcinomas and 3 benign nodules); score 5 in 17 nodules (14 papillary carcinomas and 3 benign nodules); and score 6 in 3 nodules (all papillary carcinomas). A VTI elasticity score of 4 or greater was highly predictive of malignancy (P, .01), and the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 87.0% (67 of 77), 95.8% (136 of 142), 91.8% (67 of 73), 93.1% (136 of 146), and 92.7% (203 of 219), respectively.

The re-classification of tumors ,1 and ≤2 cm limited to the thyroid from the T2 to the T1 category triggered some concerns about their best management. In order to identify possible predictors of disease outcome, several clinico-pathological features were analyzed by uni- and multivariate analyses in a retrospective consecutive series of 251 PTCs ≤2 cm. Moreover, since 37% of cases were submitted to prophylactic central compartment node dissection (CLND, VI-VII levels) and ...
Multiple studies have shown that papillary microcarcinomas are very low risk and are unlikely to grow and/or spread. As such, there is significant interest in confirming whether or not thyroid surgery can be avoided for at least some people diagnosed with papillary microcarcinoma. The purpose of the study is to provide better understanding of the risk of cancer growth and spread for patients diagnosed with papillary thyroid microcarcinoma to determine whether or not thyroid surgery is needed for such patients. ...
immune Uncategorized Dovitinib Dilactic acid, Rabbit Polyclonal to CEBPD/E Papillary thyroid carcinomas (PTCs) occasionally form multiple tumor foci in various sites of the same thyroid gland. demonstrated a concordant inactivation design Dovitinib Dilactic acid from the X-chromosome. AS-PCR indicated that mutational position between your tumor foci was discordant in three (25%) and concordant in nine (75%) of 12 obtainable situations. Once the total outcomes of the two molecular analyses had been mixed, 28.6% from the cases were discordant in X-chromosome inactivation design and/or mutation, recommending multicentric origin. A number of the remaining concordant situations could be of multicentric origins also. These total outcomes support a hypothesis that multicentric incident in multiple PTCs could be common, possibly higher than 30%. Even though specific system of multicentric incident is normally unclear still, our findings donate to the understanding the histogenesis of papillary thyroid ...
eng] INTRODUCTION: Proliferation and apoptosis are opposing processes by which the cell numbers are kept in a delicate balance, essential for tissue homeostasis, whereas uncontrolled growth of cells is a hallmark of cancer. Papillary thyroid cancer (PTC) is the commonest type of thyroid cancer, with some PTC following an indolent course, whereas the other ones are more aggressive. AIM: To evaluate respective contribution of proliferation and apoptosis in the tumorigenesis of PTC by automated analysis. MATERIALS AND METHODS: We investigated the immunolabeling of phosphorylated histone H3 (pHH3), cyclin D1, active caspase-3, and bcl-2 in thirteen cases each of metastatic PTC, follicular variant of PTC (FVPTC), papillary microcarcinoma (PMC) and well differentiated tumor of uncertain malignant potential (WDT-UMP).

The planning of surgery methods and patient evaluation in the thyroid cancer surgery has been subjected to up to date discussions with the over again description of cytological classification after the development of high-resolution ultrasound and fine needle aspiration biopsy. Papillary carcinomas consist of nearly 85% of all thyroid cancers and of them papillary thyroid microcarcinomas (PTM) constitute 30-56%. At the late 1980s, PTM defined as the papillary thyroid carcinomas (PTC) those are ≤1 cm at the largest diameter. In the international guidelines of thyroid cancer diagnosis and management, PTM and PTC diagnosis are the main factors that effect the surgical method. The management steps of papillary thyroid cancer begin with surgical removing of the primary tumor, the part overspilling from thyroid capsule and affected lymphoid ganglions. The main principle is retaining the morbidity in minimal during surgery with the extent of surgery according with ...
Papillary carcinoma (PTC) is the most common form of well-differentiated thyroid cancer, and the most common form of thyroid cancer to result from exposure to radiation. Papillary carcinoma appears as an irregular solid or cystic mass or nodule in a normal thyroid parenchyma.

Background: Inactivation of p16 by methylation of CpG islands is a frequent early event in human cancers, including papillary thyroid carcinoma (PTC). This study was to observe the methylation status of the p16 gene in papillary thyroid carcinoma (PTC) and its correlation with clinical parameters.. Methods: Methylation-specific PCR (MSP) was used to analyze the methylation status of the p16 gene in 74 PTCs and 21 adjacent normal thyroid tissues.. Results: Hypermethylation of p16 gene was observed in 27.0% (20/74) of PTC. None of the normal thyroid tissues was methylated, when compared to the PTCs (p < 0.05). There was no marked relationship between the methylation of p16 gene and the patients′ age, gender, size of cancer, histological subtypes and occurrence of recurrent disease (p > 0.05). The methylation of p16 gene was positively associated with metastasis, a high AMES (age, metastasis to distant sites, extrathyroidal invasion, size) risk group (p < 0.05) and advanced pathological tumor ...

Classical papillary thyroid microcarcinoma (PTMC) is a variant of papillary thyroid carcinoma (PTC) known to have excellent prognosis. It has a mortality of 0.3%, even in the presence of distance metastasis. The latest American Thyroid Association guidelines state that although lobectomy is acceptable, active surveillance can be considered in the appropriate setting. We present the case of a 37-year-old female with a history of PTMC who underwent surgical management consisting of a total thyroidectomy. Although she has remained disease-free, her quality of life has been greatly affected by the sequelae of this procedure. This case serves as an excellent example of how first-line surgical treatment may result more harmful than the disease itself. ...
Paired box gene 8 (PAX8) is expressed in and indispensable to thyroid development. MiR-144-3p is found dys-regulated in cancers, and it can block the expression of target gens. This study sought to understand the effect of MiR-144-3p in papillary thyroid carcinoma (PTC) as well as the associated mechanisms. Real-time PCR, immunohistochemical and Western blot assays were performed to examine the expression of target miRNA and/or genes. CCK-8 and flow cytometry analysis was used to respectively test cell growth, cell cycle progression and apoptosis. Luciferase reporter assay was performed to find out whether miR-144-3p could bind to the 3′ untranslated region of PAX8 or not. We found that PAX8 decreased in PTC, while miR-144-3p increased in PTC. Over-expression of miR-144-3p promoted the cell viability and cell cycle progression. The expressions of cell-cycle-related genes, cyclin D1, cyclin-dependent kinase 2 and CDC25A were modulated by miR-144-3p. Meanwhile, the presence or absence of miR-144-3p both
