Anaplasia
Loss of structural differentiation and useful function of neoplastic cells.
Wilms Tumor
A malignant kidney tumor, caused by the uncontrolled multiplication of renal stem (blastemal), stromal (STROMAL CELLS), and epithelial (EPITHELIAL CELLS) elements. However, not all three are present in every case. Several genes or chromosomal areas have been associated with Wilms tumor which is usually found in childhood as a firm lump in a child's side or ABDOMEN.
Rhabdomyosarcoma, Embryonal
A form of RHABDOMYOSARCOMA arising primarily in the head and neck, especially the orbit, of children below the age of 10. The cells are smaller than those of other rhabdomyosarcomas and are of two basic cell types: spindle cells and round cells. This cancer is highly sensitive to chemotherapy and has a high cure rate with multi-modality therapy. (From Holland et al., Cancer Medicine, 3d ed, p2188)
Cerebellar Neoplasms
Primary or metastatic neoplasms of the CEREBELLUM. Tumors in this location frequently present with ATAXIA or signs of INTRACRANIAL HYPERTENSION due to obstruction of the fourth ventricle. Common primary cerebellar tumors include fibrillary ASTROCYTOMA and cerebellar HEMANGIOBLASTOMA. The cerebellum is a relatively common site for tumor metastases from the lung, breast, and other distant organs. (From Okazaki & Scheithauer, Atlas of Neuropathology, 1988, p86 and p141)
Medulloblastoma
A malignant neoplasm that may be classified either as a glioma or as a primitive neuroectodermal tumor of childhood (see NEUROECTODERMAL TUMOR, PRIMITIVE). The tumor occurs most frequently in the first decade of life with the most typical location being the cerebellar vermis. Histologic features include a high degree of cellularity, frequent mitotic figures, and a tendency for the cells to organize into sheets or form rosettes. Medulloblastoma have a high propensity to spread throughout the craniospinal intradural axis. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2060-1)
Kidney Neoplasms
Tumors or cancers of the KIDNEY.

Loss of p53 promotes anaplasia and local invasion in ret/PTC1-induced thyroid carcinomas. (1/38)

Papillary thyroid carcinomas in humans are associated with the ret/PTC oncogene and, following loss of p53 function, may progress to anaplastic carcinomas. Mice with thyroid-targeted expression of ret/PTC1 developed papillary thyroid carcinomas that were minimally invasive and did not metastasize. These mice were crossed with p53-/- mice to investigate whether loss of p53 would promote anaplasia and metastasis of ret/PTC1-induced thyroid tumors. The majority of p53-/- mice died or were euthanized by 17 weeks of age due to the development of thymic lymphomas, soft tissue sarcomas, and testicular teratomas. All ret/PTC1 mice developed thyroid carcinomas, but tumors in p53-/- mice were more anaplastic, larger in diameter, more invasive, and had a higher mitotic index than tumors in p53+/+ and p53+/- mice. Thyroid tumors did not metastasize in any of the experimental p53+/+ and p53+/- mice +info)

Association of expression of CD44v6 with systemic anaplastic large cell lymphoma: comparison with primary cutaneous anaplastic large cell lymphoma. (2/38)

CD44 is a ubiquitous multifunctional cell surface adhesion molecule family. High expression of the standard form, CD44s (CD44), and its variant form, CD44v6, has been reported to be associated with tumor dissemination in non-Hodgkin lymphoma. To evaluate the potential role of CD44 and/or CD44v6 in different entities of anaplastic large cell lymphoma (ALCL), 30 cases of systemic ALCL (sALCL; 20 cases) and primary cutaneous ALCL (cALCL; 10 cases) were compared for expression of CD44 and CD44v6 by immunohistochemical staining. Expression of CD44v6 also was analyzed with respect to expression of anaplastic lymphoma kinase (ALK) in sALCL. No difference of CD44 expression was noted between sALCL and cALCL In contrast, expression of CD44v6 was found in 18 (90%) of sALCL cases and in 5 (50%) of cALCL cases. There was no correlation between expression of CD44v6 and expression of ALK in sALCL. These results indicate that expression of CD44v6 rather than CD44 correlates with sALCL. Furthermore, these results suggest that CD44v6 and ALK may be independent predictors of risk for the systemic phenotype of ALCL.  (+info)

Malignant peritoneal mesothelioma deciduoid or anaplastic variant? Point to ponder. (3/38)

A case of peritoneal mesothelioma displaying unusual morphology, occurring in a 53 year old woman is described.

The appropriate terminology to be used and possible etiologic factor are also discussed.  (+info)

Clinical and biologic significance of nuclear unrest in Wilms tumor. (4/38)

BACKGROUND: Nuclear unrest is a term applied to Wilms tumors (WT) with favorable histology that show nuclear enlargement similar to that seen in anaplasia but with no abnormal mitotic figures. This study was undertaken to evaluate the clinical and pathogenetic significance of WT with nuclear unrest. METHODS: The authors reviewed primary nephrectomy specimens and clinical data from 173 patients who were treated for WT on 1 of 5 consecutive clinical trials at St. Jude Children's Research Hospital. A subset of 70 patients was selected for p53 immunohistochemistry. Seventeen samples of recurrent tumors were also reviewed. RESULTS: WT with nuclear unrest had age and stage distribution similar to that for WT with favorable histology. Patients who had tumors with favorable histology, nuclear unrest, and anaplastic histology had 5-year cumulative incidences of recurrence of 12.2%, 22.2%, and 36.4%, respectively (P = 0.010). Despite the difference in recurrence incidence, patients who had tumors with nuclear unrest and patients who had tumors with favorable histology had nearly identical overall survival. Immunostaining for p53 was positive in 2 of 24 tumors (8.3%) with favorable histology, 1 of 25 tumors (4%) with nuclear unrest, and 16 of 21 tumors (76%) with anaplastic histology (P < 0.001). Histologic review of samples from recurrent tumors showed that 7 of 10 of primary tumors converted from favorable histology to either nuclear unrest or anaplastic histology in the recurrent tumor. CONCLUSIONS: WT with nuclear unrest more closely resembles favorable histology than anaplastic histology, both clinically and pathogenetically. Analysis of samples from recurrent tumors suggests that WT with nuclear unrest represents an intermediary in the continuum from favorable histology to anaplastic histology. For treatment stratification, it is appropriate to continue grouping nuclear unrest with favorable histology, although a larger analysis will be necessary to confirm the current findings.  (+info)

Gangliogliomas: A report of five cases. (5/38)

Gangliogliomas are rare tumors of the Central Nervous System. Five gangliogliomas were diagnosed out of 1560 brain tumours surgically resected out in a period of 5 years accounting for 0. 32%. We have tried to discuss in detail the pathological features of these tumours and have mentioned the clinical and radiological features associated with them. All the slides, tissue blocks and pathology reports of the surgical specimens of gangliglioma were reviewed and the clinical and radiological data reviewed. The ages of the patients ranged from 7-65 years with 4 males and 1 female. The tumors were located in the lateral ventricle (a rare site), temporal, parietal and the frontal lobes with duration of seizures varying from 1-9 years. The tumors were diagnosed by the presence of a dual population of neoplastic ganglionic and glial components. The glial components consisted of pilocytic astrocytes (l case), fibrillary astrocytes (2 cases), oligodendrocytes (1 case) and anaplastic astrocytes and oligodendrocytes (1 case). There was one-grade I GG, three-Grade II GGs and one-grade III GG. Astrocytes were the commonest glial component of GGs, either pilocytic or fibrillary. Oligodendrocytes as the glial component of GGs was seen in 2 cases one of which was anaplastic and this is a rare finding.  (+info)

Increased p53 immunopositivity in anaplastic medulloblastoma and supratentorial PNET is not caused by JC virus. (6/38)

BACKGROUND: p53 mutations are relatively uncommon in medulloblastoma, but abnormalities in this cell cycle pathway have been associated with anaplasia and worse clinical outcomes. We correlated p53 protein expression with pathological subtype and clinical outcome in 75 embryonal brain tumors. The presence of JC virus, which results in p53 protein accumulation, was also examined. METHODS: p53 protein levels were evaluated semi-quantitatively in 64 medulloblastomas, 3 atypical teratoid rhabdoid tumors (ATRT), and 8 supratentorial primitive neuroectodermal tumors (sPNET) using immunohistochemistry. JC viral sequences were analyzed in DNA extracted from 33 frozen medulloblastoma and PNET samples using quantitative polymerase chain reaction. RESULTS: p53 expression was detected in 18% of non-anaplastic medulloblastomas, 45% of anaplastic medulloblastomas, 67% of ATRT, and 88% of sPNET. The increased p53 immunoreactivity in anaplastic medulloblastoma, ATRT, and sPNET was statistically significant. Log rank analysis of clinical outcome revealed significantly shorter survival in patients with p53 immunopositive embryonal tumors. No JC virus was identified in the embryonal brain tumor samples, while an endogenous human retrovirus (ERV-3) was readily detected. CONCLUSION: Immunoreactivity for p53 protein is more common in anaplastic medulloblastomas, ATRT and sPNET than in non-anaplastic tumors, and is associated with worse clinical outcomes. However, JC virus infection is not responsible for increased levels of p53 protein.  (+info)

Multiple metastases to the small bowel from large cell bronchial carcinomas. (7/38)

AIM: Metastases from lung cancer to gastrointestinal tract are not rare at postmortem studies but the development of clinically significant symptoms from the gastrointestinal metastases is very unusual. METHODS: Formalin-fixed, paraffin-embedded tissues were cut into 5 microm thick sections and routinely stained with hematoxylin and eosin. Some slides were also stained with Alcian-PAS. Antibodies used were primary antibodies to pancytokeratin, cytokeratin 7, cytokeratin 20, epithelial membrane antigen, vimentin, smooth muscle actin and CD-117. RESULTS: We observed three patients who presented with multiple metastases from large cell bronchial carcinoma to small intestine. Two of them had abdominal symptoms (sudden onset of abdominal pain, constipation and vomiting) and in one case the tumor was incidentally found during autopsy. Microscopically, all tumors showed a same histological pattern and consisted almost exclusively of strands and sheets of poorly cohesive, polymorphic giant cells with scanty, delicate stromas. Few smaller polygonal anaplastic cells dispersed between polymorphic giant cells, were also observed. Immunohistochemistry showed positive staining of the tumor cells with cytokeratin and vimentin. Microscopically and immunohistochemically all metastases had a similar pattern to primary anaplastic carcinoma of the small intestine. CONCLUSION: In patients with small intestine tumors showing anaplastic features, especially with multiple tumors, metastases from large cell bronchial carcinoma should be first excluded, because it seems that they are more common than expected.  (+info)

Salvage chemotherapy with cyclophosphamide for recurrent temozolomide-refractory anaplastic astrocytoma. (8/38)

BACKGROUND: A prospective Phase II study of cyclophosphamide (CYC) was conducted in adult patients with recurrent temozolomide-refractory anaplastic astrocytoma (AA) with a primary objective of evaluating 6-month progression-free survival (PFS). METHODS: Forty patients (28 men, 12 women) ages 26-57 years (median, 43 yrs) with neuroradiographically recurrent AA were treated. All patients had previously been treated with surgery and involved-field radiotherapy. Additionally, all patients were treated with temozolomide (TMZ) chemotherapy after radiotherapy. All patients were treated at recurrence with CYC administered intravenously on 2 consecutive days (750 mg/m2/day) every 4 weeks (operationally defined as a single cycle). Neurologic and neuroradiographic evaluation were performed every 8 weeks. RESULTS: All patients were evaluable. A total of 215 cycles of CYC (median, 4 cycles; range 2-12 cycles) was administered. CYC-related toxicity included alopecia (all patients, 100%), anemia (5, 12.5%), thrombocytopenia (6, 15%), and neutropenia (8, 20%). Four (10%) patients required transfusion. Nine patients (22.5%) (95% confidence interval [95% CI], 11%-39%) demonstrated a neuroradiographic partial response, 16 patients (40.0%) (95% CI, 25%-57%) demonstrated stable disease, and 15 patients (37.5%) (95% CI, 23%-54%) had progressive disease after 2 cycles of CYC. Time to tumor progression ranged from 2-19 months (median, 4 mos; 95% CI, 2-6 mos). Survival ranged from 2-26 months (median, 8 mos; 95% CI, 6-10 mos). The 6-month and 12-month PFS was 30% and 8%, respectively. CONCLUSIONS: CYC demonstrated modest efficacy with acceptable toxicity in this cohort of adult patients with recurrent anaplastic astrocytoma, all of whom had failed prior TMZ chemotherapy.  (+info)

Thyroid cancer - wikidocThyroid cancer - wikidoc
Thyroid cancer refers to any of four kinds of tumors of the thyroid gland which include papillary, follicular, medullary and anaplastic tumors. Papillary and follicular tumors are the most common and are usually benign. Papillary and follicular tumors have a slow growth and may recur, but are generally not fatal in patients under 45 years of age. Medullary and anaplastic tumors are malignant. Medullary tumors have a good prognosis if the are restricted to the thyroid gland and a poorer prognosis if metastasis occurs. Anaplastic tumors are fast-growing and respond poorly to therapy. Thyroid nodules are diagnosed by ultrasound guided fine needle aspiration or frequently by thyroidectomy (surgical removal and subsequent histological examination). As the thyroid cancer can uptake iodine, radioactive iodine is commonly used for the treatment of thyroid carcinomas. However, radioactive iodine therapy is accompanied by thyroxine therapy to ensure TSH suppression. ...

Brain tumor - WikipediaBrain tumor - Wikipedia
Tumors have characteristics that allow determination of malignancy and how they will evolve, and determining these characteristics will allow the medical team to determine the management plan. Anaplasia or dedifferentiation: loss of differentiation of cells and of their orientation to one another and blood vessels, a characteristic of anaplastic tumor tissue. Anaplastic cells have lost total control of their normal functions and many have deteriorated cell structures. Anaplastic cells often have abnormally high nuclear-to-cytoplasmic ratios, and many are multinucleated. Additionally, the nuclei of anaplastic cells are usually unnaturally shaped or oversized. Cells can become anaplastic in two ways: neoplastic tumor cells can dedifferentiate to become anaplasias (the dedifferentiation causes the cells to lose all of their normal structure/function), or cancer stem cells can increase their capacity to multiply (i.e., uncontrollable growth due to failure of differentiation). Atypia: an indication ...

The identification of EGFR overexpression in a significant proportion of anaplastic Wilms tumors and mesoblastic nephromas highlights the potential for targeted therapy in a histologically defined subset of children with renal malignancies. In particular, there was a striking association with CCSK, the second most common renal tumor in children following Wilms tumor, which has a significantly reduced survival (15), and for which the molecular genetics underlying the disease are largely unknown. We have observed an up-regulation of the EGFR pathway in all cases of CCSK examined, as suggested by a recent expression profiling study (10). This involved a combination of overexpression, gene amplification, p-Akt up-regulation, and mutations in both EGFR and PTEN.. Of particular interest is the discovery of a somatic T790M mutation in EGFR in an untreated case of CCSK. Despite the initial success of compounds targeting the receptor in patients with activating EGFR mutations, resistance seems to ...

Renal anaplastic sarcoma - WikipediaRenal anaplastic sarcoma - Wikipedia
Renal anaplastic sarcoma is a rare tumour of the kidney. By 2017 about 25 cases have been reported. This tumour occurs in children and young adults and is more common in females than males. Because of its rarity its natural history is not well understood. The age at diagnosis of this condition varies between 10 months to 41 years. The male:female ratio is 2:3. The most common presentation is an asymptomatic abdominal mass. The tumour is more common on the right and it may metastise to lung, liver and bone. Aspiration cytology may be of use in making the diagnosis. CT scans of the abdomen and the rest of the body are normally done to assist in surgical planning. On histology the tumours have a marked spindle cell component. Other cells may be bizarre in shape. Cartilage or bone tissue may be found. A cystic component may be present. The differential diagnosis includes anaplastic Wilms tumor renal synovial sarcomas malignant mesenchymomas ectomesenchymomas An association with mutations in the ...

BACKGROUND: Diffuse anaplastic Wilms tumor (DAWT) is a rare, high-risk subtype that is often missed on diagnostic needle biopsy. Somatic mutations in TP53 are associated with the development of anaplasia and with poorer survival, particularly in advanced-stage disease. Early identification of DAWT harboring TP53 abnormalities could improve risk stratification of initial therapy and monitoring for recurrence. METHODS: Droplet digital polymerase chain reaction (ddPCR) was used to evaluate 21 samples from 4 patients with DAWT. For each patient, we assessed TP53 status in frozen tumor, matched germline DNA, and circulating tumor DNA (ctDNA) from plasma, serum, and urine collected throughout treatment. RESULTS: Mutant TP53 was detectable in ctDNA from plasma and serum in all patients. We did not detect variant TP53 in the same volume (200 μl) of urine. One patient displayed heterogeneity of TP53 in the tumor despite both histological sections displaying anaplasia. Concentration of ctDNA from ...

Hodgkin Lymphoma and Anaplastic Variants of Non-Hodgkin LymphomaHodgkin Lymphoma and Anaplastic Variants of Non-Hodgkin Lymphoma
Background and Objectives: Classic Hodgkin lymphoma (CHL), anaplastic large cell lymphoma (ALCL) and some cases of diffuse large B cell lymphoma (DLBCL) have overlapping morphologic features. Since they all represent distinct clinico-pathologic entities, we explored the differential diagnostic impact of immunophenotyping to discriminate between them. Materials and Methods: We included 61 cases diagnosed as CHL, ALCL, and anaplastic variant of DLBCL. We reviewed morphologic microscopic findings by conventional staining and immunohistochemistry (IHC) with antibodies against PAX-5, CD30, CD15, CD45, EMA, ALK-1, and LMP-1. Results: Fifty cases corresponded to CHL (81.97%), 4 cases to ALCL (6.56%), and 4 cases to DLBCL (6.56%) excluding 3 cases, which remained unclassifiable (4.92%). PAX-5 was expressed in 94% of CHL and 100% of DLBCL cases. LMP-1 was expressed in 52% of CHL and 25% of DLBCL cases. EMA was invariably expressed in all 4 cases of ALK+ALCL. It was expressed in 4/50 cases (8%) of CHL and in

Genomic gain of the proto-oncogene transcription factor gene MYCN is associated with poor prognosis in several childhood cancers. Here we present a comprehensive copy number analysis of MYCN in Wilms tumour (WT), demonstrating that gain of this gene is associated with anaplasia and with poorer relapse-free and overall survival, independent of histology. Using whole exome and gene-specific sequencing, together with methylation and expression profiling, we show that MYCN is targeted by other mechanisms, including a recurrent somatic mutation, P44L, and specific DNA hypomethylation events associated with MYCN overexpression in tumours with high risk histologies. We describe parallel evolution of genomic copy number gain and point mutation of MYCN in the contralateral tumours of a remarkable bilateral case in which independent contralateral mutations of TP53 also evolve over time. We report a second bilateral case in which MYCN gain is a germline aberration. Our results suggest a significant role ...

Malignancy - WikipediaMalignancy - Wikipedia
Malignancy (from Latin male, meaning badly, and -gnus, meaning born) is the tendency of a medical condition to become progressively worse. Malignancy is most familiar as a characterization of cancer. A malignant tumor contrasts with a non-cancerous benign tumor in that a malignancy is not self-limited in its growth, is capable of invading into adjacent tissues, and may be capable of spreading to distant tissues. A benign tumor has none of those properties. Malignancy in cancers is characterized by anaplasia, invasiveness, and metastasis.[1] Malignant tumors are also characterized by genome instability, so that cancers, as assessed by whole genome sequencing, frequently have between 10,000 and 100,000 mutations in their entire genomes.[2] Cancers usually show tumour heterogeneity, containing multiple subclones.[3] They also frequently have reduced expression of DNA repair enzymes due to epigenetic methylation of DNA repair genes or altered microRNAs that control DNA repair gene expression. ...

Cell-free DNA (cfDNA) and circulating tumor cells (CTCs) are promising prognostic and predictive biomarkers in non-small cell lung cancer (NSCLC). In this study, we examined the prognostic role of cfDNA and CTCs, in separate and joint analyses, in NSCLC patients receiving first line chemotherapy. Seventy-three patients with advanced NSCLC were enrolled in this study. CfDNA and CTC were analyzed at baseline and after two cycles of chemotherapy. Plasma cfDNA quantification was performed by quantitative PCR (qPCR) whereas CTCs were isolated by the ScreenCell Cyto (ScreenCell, Paris, France) device and enumerated according to malignant features. Patients with baseline cfDNA higher than the median value (96.3 hTERT copy number) had a significantly worse overall survival (OS) and double the risk of death (hazard ratio (HR): 2.14; 95% confidence limits (CL) = 1.24-3.68; p-value = 0.006).

Cancer cells are immature cells resulting from cellular reprogramming by gene misregulation, and redifferentiation is expected to reduce malignancy. It is unclear, however, whether cancer cells can undergo terminal differentiation. Here, we show that inhibition of the epigenetic modification enzyme enhancer of zeste homolog 2 (EZH2), histone deacetylases 1 and 3 (HDAC1 and -3), lysine demethylase 1A (LSD1), or DNA methyltransferase 1 (DNMT1), which all promote cancer development and progression, leads to postmitotic neuron-like differentiation with loss of malignant features in distinct solid cancer cell lines. The regulatory effect of these enzymes in neuronal differentiation resided in their intrinsic activity in embryonic neural precursor/progenitor cells. We further found that a major part of pan-cancer-promoting genes and the signal transducers of the pan-cancer-promoting signaling pathways, including the epithelial-to-mesenchymal transition (EMT) mesenchymal marker genes, display neural ...

Pleomorphic Xanthoastrocytoma with anaplastic features | Cancer Survivors NetworkPleomorphic Xanthoastrocytoma with anaplastic features | Cancer Survivors Network
My wife had brain surgery on 15th of May. The doctors said that they had removed all of that growth. Now after nearly one and a half month of the operation, I recollect all the symptoms and changes in her behaviour which started about a month prior to the operation.. She used to be an active lady and never showed her phycscal weakness to others. But I started noticing her tired looks. Sometimes she used to drop things like lunch box, forgot to close kitchen cabinets and fridge door and to switch off lights of rooms. We had little arguments over these. Once we were comming out of a party and she stood in the middle of stairs I observed that her left foot was out of sandle. I asked if the footware is broken. She looked at me in a strange way and noded. Actually she was not aware of it. We blamed it on her weakness due to some gynec problem and sought appointment for that. During that period her condition deteriorated. While walking her left hand was not moving freely, left leg also became slow and ...

Chondrosarcoma
Imaging studies - including radiographs (x-rays), computerized tomography (CT), and magnetic resonance imaging (MRI) - are often used to make a presumptive diagnosis of chondrosarcoma. However, a definitive diagnosis depends on the identification of malignant cancer cells producing cartilage in a biopsy specimen that has been examined by a pathologist. In a few cases, usually of highly anaplastic tumors, immunohistochemistry (IHC)is required.. There are no blood tests currently available to enable an oncologist to render a diagnosis of chondrosarcoma. The most characteristic imaging findings are usually obtained with CT.. Nearly all chondrosarcoma patients appear to be in good health. Often, patients are not aware of the growing tumor until there is a noticeable lump or pain. Earlier diagnosis is generally accidental, when a patient undergoes testing for another problem and physicians discover the cancer. Occasionally the first symptom will be a broken bone at the cancerous site. Any broken ...

The goal of this work was to demonstrate prospectively that maximal surgical resection of low grade oligodendrogliomas without adjuvant therapy does not reduce life expectancy over that of historical controls. All patients with surgically accessible grade II oligodendrogliomas underwent maximal resection using stereotactic guidance and/or cortical mapping and were followed with serial MRI scans without adjuvant therapy until either progression or spread into brain regions deemed not surgically resectable. Nineteen patients were treated between 1993 and 2006. Ten patients required reoperation an average of 55 months after their first surgery. Nine patients progressed to anaplastic tumors an average of 42 months after their first surgery: six patients died from their tumors an average of 73 months after diagnosis, two are still alive 76 and 18 months after progression, and one was lost to follow up. Ten patients are alive and progression-free an average of 116 months after diagnosis, one of whom was lost

THE PROGRESSION TO CARCINOMA OF VIRUS-INDUCED RABBIT PAPILLOMAS (SHOPE) | JEMTHE PROGRESSION TO CARCINOMA OF VIRUS-INDUCED RABBIT PAPILLOMAS (SHOPE) | JEM
The papillomas induced in domestic rabbits with virus procured from cottontails undergo progressive changes in the direction of malignancy when they grow vigorously. From the beginning they exhibit the traits whereby tumors are characterized, and they have malignant potentialities. In seven animals of a group of ten carrying papillomas for more than 200 days, cancer has developed, and in an eighth a tumor of problematic malignancy has arisen. One of the remaining two rabbits died early in the cancer period, and the papillomas of the other eventually retrogressed. Ten cottontails with induced growths of much longer duration have not developed cancer.. The malignant tumors have all been acanthomatous in type, and have arisen directly from the papillomas by graded, continuous alterations. These have often gone further after malignancy has been attained, and have eventuated in great anaplasia. Metastasis has been frequent, and transplantation to another host has proved successful. Individual growths ...

cyld displays a dominant genetic linkage to multiple types of cutaneous adnexal tumors that often develop in bulky clusters in the head, neck, trunk, and pubic areas (10, 37). Although predominantly benign (10), these tumors are painful and disfiguring, can undergo malignant transformation with metastasis over time, and eventually lead to mortality (38-41). Thus, the malignant features of the tumors developed on K14-CYLDm transgenic mice are in line with the clinical manifestations seen in patients. Our transgenic tumor models allowed us to define JNK/AP1 signaling cascade as a key regulator in CYLDm-driven epidermal malignancy.. Cyld loss of function is not only relevant to cutaneous adnexal tumors but also to many other cancers including SCC (22,42). It is worth noting that cyld−/− mice are sensitive to chemically induced carcinogenesis, but the tumors developed on these mice are not more malignant than those of WT mice (22). We predict that the differential tumor growth phenotypes ...

Diffuse Large B-Cell Lymphoma with Anaplastic Clear Cells: A Rare VariantDiffuse Large B-Cell Lymphoma with Anaplastic Clear Cells: A Rare Variant
Introduction: Diffuse Large B-Cell Lymphoma (DLBCL) is a heterogeneous group conformed by morphological and clinical varieties of neoplasms; it originates from peripheral B-cells and is distinguished into three groups: germinal center (GC), activated B lymphocyte (ABL), and the third type. The existence of DLBCL with anaplastic morphology and expression of CD30 without t (2; 5) translocation is rare. The aim of the present article is to describe this morphologic variant in a 54-year-old woman and a 74-year-old man, respectively. Materials and Methods: Patients diagnosed with DLBCL with anaplastic variant were identified from the surgical pathology records. Results: Out of 357 biopsies with this diagnosis, 11 (3%) corresponded to the anaplastic variant, 2 presented morphological clear cells; they became visible because of an increase in volume in the cervical area of 4 months of evolution, usually associated to diaphoresis and weight loss with clinical fulminating progression.

Feb 158 (2): Although several genes/genetic loci involved in the etiolgy of wilms tumor have been identified, little is known of the molecular changes associated with relapse. We therfore undertook an analysis by comparative genomic hybridization (CGH) of 58 tumor samples of favorable histology Wilms tumor taken at inital diagnosis and/or relapse. The results suggest that 1q gain at diagnosis could be used to identify patients with favorable histology Wilms tumor at increased risk of relapse who might benefit from early treatment intensification.. ...

CEBPD (C/EBP delta) is a member of the CCAAT-enhancer binding protein (C/EBP) family of transcription factors characterized by a b-Zip domain that mediates dimerization and DNA binding. CEBPD is induced in response to acute stressors such as cytokine stimulation, bacterial lipopolysaccharide (LPS), corticosteroids, radiation and hypoxia. We have previously reported that CEBPD has dual functions in breast cancer by both attenuating or enhancing oncogenic pathways depending on context (Balamurugan and Sterneck, 2013, Mendoza-Villanueva et al., 2016). Recent studies reveal that elevated Endoplasmic Reticulum (ER) stress is associated with the pathology of several diseases including cancer. Limiting supply of nutrients and oxygen in growing tumor cells disrupts the protein folding homeostasis resulting in activation of the unfolded protein response (UPR). The UPR includes pathways that support adaptation to stress, and that are also implicated in promoting malignant features and therapy resistance ...

Background and Objectives: Multiple myeloma (MM) defines as monoclonal antibody producing abnormal plasma cells inhabiting bone marrow (BM). It involves multiple genetic mutations where different signaling pathways get deregulated hence showing malignant features of myeloma. Increased relative telomerase activity (RTA) and altered levels of shelterin complex molecules (TRF1, TRF2, POT1, RAP1, TIN2, TPP1) along with its associated molecules (TANK-1 & PINX1) are underlying principle behind several malignancies. This maiden attempt aims to study expression levels of these molecules in myeloma and revealing therapeutic potential of TanshinoneI (TanI) alone or in combination with lenalidomide by targeting telomerase activity and shelterin molecules.. Methodology:Newly diagnosed 50 MM patients & 20 controls were recruited for BM aspiration with their consent. RTA, mean telomere length, relative mRNA and protein levels were studied in study subjects. Clinical parameters were recorded; correlation was ...

Pathology of Malignant Rhabdoid Tumour of Kidney - Dr Sampurna Roy MD
Electron microscopy shows the inclusions to be composed of whorls of cytoplasmic filaments with a few included organelles and lipid droplets.. Other renal tumours may simulate MRT or show rhabdoid features. These include Wilms tumour itself, renal cell carcinoma, cellular examples of mesoblastic nephroma, and medullary cell carcinoma.. Clear Cell Sarcoma of the Kidney , MRTK and Wilms Tumour with anaplasia are referred to as tumours with unfavourable histology for the purposes of deciding treatment.. Extra-renal rhabdoid tumour is a controversial entity, and has now been described in many sites. Many turn out to be other tumours (neural, epithelial, myoid, mesenchymal, ependymal) when fully investigated.. While renal rhabdoid tumours peak in infancy, reports of extrarenal rhabdoid tumours show a bimodal pattern with a peak in infancy and a second peak in older children tailing into adulthood.. Extra-renal rhabdoid tumours seldom have second intracranial tumours or cause the hypercalcaemia seen ...

A microscopic study of fluid taken from the liver by needle will be done to detect dysplasia (a pre-cancerous change in cells and tissues) and overt malignant features of cancerous cell spread. Occasionally, the only finding of the study is necrotic (dead) cells in the liver. A hepatic biopsy will need to be conducted in order to make a conclusive diagnosis. This will require that your veterinarian surgically remove a sample of liver tissue for laboratory analysis. A needle biopsy is not recommended.. ...

Brainstem glioma is impossible to resect completely, and patients with this type of glioma show a poor prognosis. Therefore, a more effective adjuvant therapy is required to prolong survival. Bevacizumab is an endothelial growth factor monoclonal antibody with strong anti-vascular effects, which may suppress tumor progression. We performed a retrospective study of data from 6 patients with brainstem glioma showing malignant features who were treated with bevacizumab. Tumor-associated lesions, as evaluated by T2 weighted or fluid-attenuated inversion-recovery magnetic resonance imaging, were reduced in all patients, although the timing of the start of bevacizumab administration and pretreatment were not uniform ...

Desmoplastic infantile gangliogliomas are a form of desmoplastic infantile tumours, and despite their aggressive appearances tend to have a good prognosis. Epidemiology The vast majority occur in children with less than one year of age, and males are more commonly affected with a M:F ratio of approximately 2:1 Clinical presentation A rapidly increasing head circumference is the most common presentation, with symptoms usually presenting in a short time (5 days to 3 months). Seizure activity is uncommon. Radiographic features Desmoplastic infantile ganglioglioma manifests as an exceptionally large cerebral hemispheric mass composed of both cystic and solid portions. The frontal and parietal lobes are the most common sites. CT The solid portion of these large masses is typically slightly hyperattenuating and usually located along the cortical margin of the mass. Following administration of contrast, these masses usually enhance intensely, and may demonstrate a dural tail. Calcification is not a ...
