Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.
Passages within the liver for the conveyance of bile. Includes right and left hepatic ducts even though these may join outside the liver to form the common hepatic duct.

Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors.

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.
The loss of one allele at a specific locus, caused by a deletion mutation; or loss of a chromosome from a chromosome pair, resulting in abnormal HEMIZYGOSITY. It is detected when heterozygous markers for a locus appear monomorphic because one of the ALLELES was deleted.

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.
A condition characterized by poorly-circumscribed gelatinous masses filled with malignant mucin-secreting cells. Forty-five percent of pseudomyxomas arise from the ovary, usually in a mucinous cystadenocarcinoma (CYSTADENOCARCINOMA, MUCINOUS), which has prognostic significance. Pseudomyxoma peritonei must be differentiated from mucinous spillage into the peritoneum by a benign mucocele of the appendix. (Segen, Dictionary of Modern Medicine, 1992)
The condition of an anatomical structure's being dilated beyond normal dimensions.
A malignant cystic or semicystic neoplasm. It often occurs in the ovary and usually bilaterally. The external surface is usually covered with papillary excrescences. Microscopically, the papillary patterns are predominantly epithelial overgrowths with differentiated and undifferentiated papillary serous cystadenocarcinoma cells. Psammoma bodies may be present. The tumor generally adheres to surrounding structures and produces ascites. (From Hughes, Obstetric-Gynecologic Terminology, 1972, p185)

High frequency of germ-line BRCA2 mutations among Hungarian male breast cancer patients without family history. (1/1031)

To determine the contribution of BRCA1 and BRCA2 mutations to the pathogenesis of male breast cancer in Hungary, the country with the highest male breast cancer mortality rates in continental Europe, a series of 18 male breast cancer patients and three patients with gynecomastia was analyzed for germ-line mutations in both BRCA1 and BRCA2. Although no germ-line BRCA1 mutation was observed, 6 of the 18 male breast cancer cases (33%) carried truncating mutations in the BRCA2 gene. Unexpectedly, none of them reported a family history for breast/ovarian cancer. Four of six truncating mutations were novel, and two mutations were recurrent. Four patients (22%) had a family history of breast/ovarian cancer in at least one first- or second-degree relative; however, no BRCA2 mutation was identified among them. No mutation was identified in either of the genes in the gynecomastias. These results provide evidence for a strong genetic component of male breast cancer in Hungary.  (+info)

VEGFR-3 and its ligand VEGF-C are associated with angiogenesis in breast cancer. (2/1031)

Recently, monoclonal antibodies against the human vascular endothelial growth factor receptor VEGFR-3 were shown to provide a specific antigenic marker for lymphatic endothelium in various normal tissues. In this study we have investigated the expression of VEGFR-3 and its ligand VEGF-C in normal breast tissue and in breast tumors by immunohistochemistry. VEGFR-3 was weakly expressed in capillaries of normal breast tissue and in fibroadenomas. In intraductal breast carcinomas, VEGFR-3 was prominent in the "necklace" vessels adjacent to the basal lamina of the tumor-filled ducts. VEGF receptor 1 and 2 as well as blood vessel endothelial and basal lamina markers were colocalized with VEGFR-3 in many of these vessels. Antibodies against smooth muscle alpha-actin gave a weak staining of the necklace vessels, suggesting that they were incompletely covered by pericytes/smooth muscle cells. A highly elevated number of VEGFR-3 positive vessels was found in invasive breast cancer in comparison with histologically normal breast tissue (P < 0.0001, the Mann-Whitney test). VEGF-C was located in the cytoplasm of intraductal and invasive cancer cells. The results demonstrate that the expression of VEGFR-3 becomes up-regulated in the endothelium of angiogenic blood vessels in breast cancer. The results also suggest that VEGF-C secreted by the intraductal carcinoma cells acts predominantly as an angiogenic growth factor for blood vessels, although this paracrine signaling network between the cancer cells and the endothelium may also be involved in modifying the permeabilities of both blood and lymphatic vessels and metastasis formation.  (+info)

Vascular stroma formation in carcinoma in situ, invasive carcinoma, and metastatic carcinoma of the breast. (3/1031)

The generation of vascular stroma is essential for solid tumor growth and involves stimulatory and inhibiting factors as well as stromal components that regulate functions such as cellular adhesion, migration, and gene expression. In an effort to obtain a more integrated understanding of vascular stroma formation in breast carcinoma, we examined expression of the angiogenic factor vascular permeability factor (VPF)/vascular endothelial growth factor (VEGF); the VPF/VEGF receptors flt-1 and KDR; thrombospondin-1, which has been reported to inhibit angiogenesis; and the stromal components collagen type I, total fibronectin, ED-A+ fibronectin, versican, and decorin by mRNA in situ hybridization on frozen sections of 113 blocks of breast tissue from 68 patients including 28 sections of breast tissue without malignancy, 18 with in situ carcinomas, 56 with invasive carcinomas, and 8 with metastatic carcinomas. A characteristic expression profile emerged that was remarkably similar in invasive carcinoma, carcinoma in situ, and metastatic carcinoma, with the following characteristics: strong tumor cell expression of VPF/VEGF; strong endothelial cell expression of VPF/VEGF receptors; strong expression of thrombospondin-1 by stromal cells and occasionally by tumor cells; and strong stromal cell expression of collagen type I, total fibronectin, ED-A+ fibronectin, versican, and decorin. The formation of vascular stroma preceded invasion, raising the possibility that tumor cells invade not into normal breast stroma but rather into a richly vascular stroma that they have induced. Similarly, tumor cells at sites of metastasis appear to induce the vascular stroma in which they grow. We conclude that a distinct pattern of mRNA expression characterizes the generation of vascular stroma in breast cancer and that the formation of vascular stroma may play a role not only in growth of the primary tumor but also in invasion and metastasis.  (+info)

An audit of breast cancer pathology reporting in Australia in 1995. (4/1031)

To measure the quality of pathology reporting of breast cancer and establish a baseline against which future changes can be measured, we audited item completeness in breast cancer reports in Australia in 1995 before the release of specific recommendations from the Australian Cancer Network. Tumour type and size were given in reports of invasive breast cancer for 93% of women, 70% had, in addition, grade and clearance of the margins while only 28% had all recommended information. The most complete items in reports were histological type of breast cancer (99.6% of cases), tumour size (94%, 95% confidence interval (CI) 92-95) and margins of excision (87%, 95% CI 85-89). Histological grade (84%, 95% CI 82-86 of cases) and presence or absence of ductal carcinoma in situ (DCIS) (79%, 95% CI 77-81) were less complete and vessel invasion (61%, 95% CI 58-63) and changes in non-neoplastic breast tissue adjacent to the breast cancer (68%, 95% CI 66-71) the least complete. Less than half the reports of DCIS reported on tumour size (49%, 95% CI 42-57), presence or absence of necrosis (41%, 95% CI 34-49) or nuclear grade (39%, 95% CI 31-46). Around 1500 reports were identified as issued by 147 laboratories and 392 pathologists; 69% of pathologists issued fewer than two reports a month in the audit. We concluded that infrequency of reporting may have contributed to incompleteness of reporting. In addition, we found significant variation across Australian states with some indication that reporting was consistently poor in one state. The audit highlighted areas for improvement for breast cancer reporting in Australia. Research evidence suggests that multifaceted strategies are needed to assist practitioners with implementing more uniform reporting standards.  (+info)

Urokinase plasminogen activator receptor (CD87) expression of tumor-associated macrophages in ductal carcinoma in situ, breast cancer, and resident macrophages of normal breast tissue. (5/1031)

Macrophages concentrate urokinase-type plasminogen activator (uPA) at the cell surface by expressing urokinase receptors (uPAR) in order to focus the pericellular space plasminogen-dependent proteolysis important in matrix remodeling and cell movement. This study examines the uPAR levels of tumor-associated macrophages (TAM) of invasive breast carcinomas, of TAMs from ductal carcinoma in situ (DCIS) and of macrophages derived from normal (non-tumor) breast tissue. TAMs from invasive breast carcinomas (n = 30), from DCIS (n = 12), and macrophages from normal breast tissue (n = 30) were cultured and immunocytochemically phenotyped by using a panel of antibodies. Urokinase receptor levels were determined by Western blot analysis and in cell-free supernatants by enzyme-linked immunosorbent assay. Urokinase receptor cell surface fluorescence intensity was determined by FACS and by confocal laser scan microscopy. Urokinase-receptor mRNA was detected by in situ hybridization. TAMs of invasive breast carcinomas and of DCIS possess significantly elevated uPAR levels compared with macrophages derived from normal breast tissue. CONCLUSIONS: activated macrophages with elevated uPAR levels belong to inflammatory areas in close vicinity of infiltrating and non-infiltrating (DCIS) tumor cells. Blood monocytes that possess elevated uPAR-levels may be selectively recruited from the bloodstream to inflammatory sites close to carcinoma cells, and/or breast cancer and precursor lesions may induce elevated uPAR-levels in TAMs by paracrine interactions.  (+info)

Primary tumour characteristics and axillary lymph node status in breast cancer. (6/1031)

This paper examines the correlation between axillary lymph node status and primary tumour characteristics in breast cancer and whether this can be used to select patients for axillary lymphadenectomy. The results are based on a retrospective analysis of 909 patients who underwent axillary dissection in our unit. Axillary lymph nodes containing metastases were found in 406 patients (44.7%), all with invasive carcinomas, but in none of the 37 carcinomas-in-situ. Nodal status was negative in all T1a tumours, but lymph node metastases were present in 16.3% and 35.7% of T1b and T1c tumours respectively. When histological grade was taken into account, positivity for grade I T1b and T1c tumours fell to 13.6% and 26.7% respectively. Lymph node metastases were found in 85% of patients with lymphovascular invasion in their tumours as compared to only 15.4% of those without and in 45.5% of oestrogen and progesterone receptor-positive tumours. When one or both hormone receptors were absent this figure was much higher. It appears that for T1a breast cancers axillary dissection is not necessary, whereas for T1b, T1c and grade I T2 tumours other histopathological parameters should be taken into consideration in deciding who should undergo axillary lymphadenectomy.  (+info)

Elevated expression of the CC chemokine regulated on activation, normal T cell expressed and secreted (RANTES) in advanced breast carcinoma. (7/1031)

Breast carcinoma is the most common malignant disease among women and the second most lethal one. In search for a better understanding of the role of cellular mediators in the progression of this disease, we investigated the potential involvement of the CC chemokine Regulated on Activation, Normal T Cell Expressed and Secreted (RANTES) in breast carcinoma progression. To this end, RANTES expression was determined in breast tumor cell lines and in sections of breast carcinomas, followed by analysis of the incidence and intensity of its expression in different stages of the disease. Our study reveals that high and physiologically relevant levels of RANTES are constitutively produced by T47D and MCF-7 breast tumor cell lines. Analysis of RANTES expression in sections of breast carcinomas demonstrates a high incidence of RANTES expression in epithelial tumor cells; the chemokine was expressed in 74% of the sections. RANTES expression was rarely detected in normal duct epithelial cells or in epithelial cells that constitute benign breast lumps, which were located in proximity to tumor cells. High incidence and intensity of RANTES expression were detected in sections of most of the patients with stage II and stage III of the disease (expression was detected in 83 and 83.3%, respectively), whereas RANTES was expressed at a lower incidence and intensity in sections of patients with stage I of breast carcinoma (55% of the cases). Most importantly, the expression of RANTES was minimally detected in sections of patients diagnosed with benign breast disorders and of women that underwent reduction mammoplasty (15.4% of the cases). These results indicate that the expression of RANTES is directly correlated with a more advanced stage of disease, suggesting that RANTES may be involved in breast cancer progression. Moreover, it is possible that in patients diagnosed with benign breast disorders, RANTES expression may be indicative of an ongoing, but as yet undetectable, malignant process.  (+info)

Prognosis in women with a carcinoma in situ of the breast: a population-based study in Sweden. (8/1031)

We studied the risk of invasive breast cancer and breast cancer death after a breast carcinoma in situ during a period when mammography screening became a nationwide practice and when breast conservation was introduced. In a study base including all 4661 women registered to the Swedish Cancer Registry for a first carcinoma in situ between 1960 and 1992, we selected a cohort of 3398 women diagnosed between 1980 and 1992. The recruitment period was chosen according to the reporting routines for the registry. The corrected survival was 97.4% after 10 years. The risk of invasive cancer was similar in the ipsilateral and contralateral breast. Women diagnosed between 1989 and 1992 ran a relative risk of 0.1 (95% confidence interval, 0.0-0.9) of dying of breast cancer, as compared with women diagnosed from 1980-1982. Residence in counties where mammography screening was available was associated with a relative risk of 0.2 (95% confidence interval, 0.0-2.1) for breast cancer death in the age groups screened. Screening mammography may have contributed to the improvement of prognosis over this time period. This study cannot distinguish between lead time effects and a "true" improvement in prognosis. The increased use of breast conservation was not associated with a worse prognosis in the group as a whole. The study indicates that at least 50% of invasive cancers occurring after treatment for in situ lesions may be new cancers.  (+info)

N2 - The host immune response has a key role in breast cancer progression and response to therapy. However, relative to primary invasive breast cancers, the immune milieu of breast ductal carcinoma in situ (DCIS) is less understood. Here, we profile tumor infiltrating lymphocytes and expression of the immune checkpoint ligand programmed death ligand 1 (PD-L1) in 27 cases of DCIS with known estrogen receptor (ER), progesterone receptor, and human epidermal growth factor 2 (HER-2) expression using tissue microarrays. Twenty-four cases were pure DCIS and three had associated invasive ductal carcinoma. Tumors were stained by immunohistochemistry for PD-L1, as well as the lymphocyte ...
Current clinicopathological parameters are useful predictors of breast ductal carcinoma in situ behaviour, but they are insufficient to define high risk patients for disease progression precisely. Thioredoxin interacting protein (TXNIP) is a key player of oxidative stress. This study aims to evaluate the role of TXNIP as a predictor of ductal carcinoma in situ progression. Tissue microarrays from 776 pure ductal carcinoma in situ and 239 mixed ductal carcinoma in situ and invasive tumors were constructed. All patients were treated at a single institution with a long-term follow-up and TXNIP expression was assessed using immunohistochemistry. TXNIP expression was investigated in terms of associations with clinicopathological and molecular features and patient outcome. Loss/reduced cytoplasmic expression of TXNIP was associated with features of aggressiveness including high nuclear grade (p=1.6x10-5), presence of comedo necrosis (p=0.001) and oestrogen receptor negative (ER-)/HER2- ductal ...

Rates of residual disease in shaved margins were determined based on ...
The incidence of breast ductal carcinoma in situ (DCIS) in the USA exceeds that of other countries. This cannot be explained entirely by the frequency of mammographic screening in the USA and may result from differences in the interpretation of mammograms and/or the frequency with which biopsies are obtained. Although the percentage of DCIS patients treated with mastectomy has decreased, the absolute number is unchanged and the use of lumpectomy with whole-breast radiotherapy has increased in inverse proportion to the decrease in mastectomy. Treatment of DCIS with tamoxifen is still limited.
Patients diagnosed with ductal carcinoma in situ (DCIS) often opt for sentinel node surgery. But will that treatment prevent breast cancer progression?
FRIDAY, Oct. 25, 2019 (HealthDay News) - For each month of delay between diagnosis and surgery for ductal carcinoma in situ (DCIS), there is slightly worse survival and an increase in risk for invasive disease, according to a study published online Sept. 27 in the Annals of Surgical Oncology.. William H. Ward, M.D., from Naval Medical Center in Portsmouth, Virginia, and colleagues used the National Cancer Database to identify women with a clinical diagnosis of DCIS between 2004 and 2014. Differences in overall survival (OS) and presence of invasion were compared for five intervals between diagnosis and surgery (≤30, 31 to 60, 61 to 90, 91 to 120, and 121 to 365 days).. The researchers identified 140,615 clinical DCIS patients, of whom 123,947 had pathologic diagnosis of DCIS and 16,668 had invasive ductal carcinoma. Overall, five-year OS was 95.8 percent, and unadjusted median delay from diagnosis to surgery was 38 days. There was a 7.4 percent increased relative risk for death for each ...

Women diagnosed with DCIS have a very good prognosis. Ten years after DCIS diagnosis, 98% to 99% of women will be alive. Based on this good prognosis, DCIS usually is treated by lumpectomy followed by radiation therapy. If the DCIS is large, a mastectomy may be recommended. Removing the opposite breast usually isnt recommended; chemotherapy usually isnt recommended either. Hormonal therapy may be recommended if the DCIS is hormone-receptor-positive.. DCIS is NOT invasive cancer. DCIS stays inside the breast milk duct. DCIS can be large or small, but it does NOT spread outside the milk duct into the surrounding normal breast tissue or into the lymph nodes or other organs. Still, if youve been diagnosed with DCIS, youre at higher risk of developing invasive breast cancer in that breast than someone who hasnt had DCIS. DCIS also is referred to as stage 0 breast cancer.. After a DCIS diagnosis in one breast, the average risk of developing either DCIS or invasive breast cancer in the OPPOSITE ...

This multicentre retrospective study is characterised by a long period of accrual (median follow-up: 136 months,; range: 16-292 months), which offers the advantage of providing interesting information about the trend of the disease. A certain number of patients (12 patients) enrolled in the first years have died during this long period of observation; other patients (47 patients) didnt return for the planned examination to the Centre of Radiotherapy where they had been treated, and were lost to follow-up. In addition only approximately 20% of patients were treated in the first period (from 1985 to 1990) and the number of cases increased progressively during the following years (Figure 1). Most of the cases belong to the two decades covered by the screening activity. Nevertheless, a large number of cases were also found in the younger age group, between 41 and 50. Increased debate and publicity about breast cancer screening after the introduction of screening programmes could have determined an ...
• Fifty breasts with nonpalpable ductal carcinoma in situ (DCIS) were examined for the presence of microinvasion, multicentricity, and number of involved ducts
The widespread adoption of screening mammography has led to an increase in the diagnosis of ductal carcinoma in situ (DCIS) of the breast. While it is estimated that 55,000 women in the US will be diagnosed with DCIS in 2013, only a small fraction of these women (~15%) will subsequently develop invasive breast cancer. However, most women with DCIS are treated as if they will develop invasive cancer. Almost a third of these women opt for a full mastectomy. In a majority of remaining women, the DCIS lesion is surgically excised with lumpectomy and, in over half of these women, additional radiation or tamoxifen treatment is provided. Thus, many women are receiving unnecessary adjuvant therapy to prevent invasive cancers that will not occur. Additionally, ~ 15% of women are not receiving adequate intervention because they will subsequently develop a subsequent invasive tumor even after receiving lumpectomy and adjuvant therapy. Identifying molecular markers that can accurately predict subsequent ...
Intraductal carcinoma of the prostate (IDCP) has been described as a lesion associated with poor prognostic features in prostate cancer. Its recognition and reporting in prostate specimens, particularly in needle biopsies, is critical as it carries significant implications for patient management. Recent histological definitions have been proposed to assist in the recognition of IDCP and to help distinguish it from lesions with similar appearance, but different clinical behaviour. In this review, a historical overview of the description of IDCP will be presented followed by a summary of the current histological diagnostic criteria and the recommendations for management and reporting of IDCP. ...

New research from Amsterdam shows that women over the age of 50 who have been diagnosed with ductal carcinoma in situ have a higher chance of being alive ten years after their diagnosis than women in the general population, according to Science Daily. Ductal carcinoma in situ is considered a disease separate from breast cancer because it is at stage 0 and does not spread around the body. However, ductal carcinoma in situ can progress into full-blown breast cancer, which is why it is still treated with surgery or surgery in combination with radiation therapy.. The researcher Dr. Lotte Elshof presented findings at the European Cancer Congress 2017. Women who have been diagnosed with ductal carcinoma in situ should feel better about their future because of these findings, which show their longevity will not be impacted by this condition..

Ductal carcinoma in situ (DCIS) is a non-obligate precursor lesion of invasive carcinoma of the breast. Current prognostic markers based on histopathological examination are unable to accurately predict which DCIS cases will progress to invasive carcinoma or recur after surgical excision. Epigenetic changes have been shown to be a significant driver of tumorigenesis, and DNA methylation of specific gene promoters provides predictive and prognostic markers in many types of cancer, including invasive breast cancer. In general, the spectrum of genes that are methylated in DCIS strongly resembles that seen in invasive ductal carcinoma. The identification of specific prognostic markers in DCIS remains elusive and awaits additional work investigating a large panel of methylatable genes by using sensitive and reproducible technologies. This review critically appraises the role of methylation in DCIS and its use as a biomarker ...

Indolent non-progressive forms of ductal carcinoma in situ are managed according to similar surgical strategies as high-risk disease, with extent of resection dictated by radiological and pathological estimates of tumour dimensions. Although adjuvant treatments might be withheld for low-risk lesions, surgical treatments incur potential morbidity, especially when mastectomy and breast reconstruction are done for widespread low-grade or intermediate-grade ductal carcinoma in situ. Low rates of deaths from breast ...
Widespread screening mammography programmes mean that ductal carcinoma in situ (DCIS), a pre-invasive breast lesion, is now more frequently diagnosed. However, not all diagnosed DCIS lesions progress to invasive breast cancer, which presents a dilemma for clinicians. As such, there is much interest in studying DCIS in the laboratory, in order to help understand more about its biology and determine the characteristics of those that progress to invasion. Greater knowledge would lead to targeted and better DCIS treatment. Here, we outline some of the models available to study DCIS, with a particular focus on animal-free systems.. ...
RESULTS: 42 of the 99 lesions (42.4%) were invasive carcinomas, 57 (57.6%) were pure ductal carcinoma in situ (DCIS). 6 out of 99 (6.1%) lesions were triple negative, and 29 (29.3%) were HER2/neu positive. Successful first excision rate was 76/99 lesions (76.8%). Breast conservation was achieved in 73.7% (73/99). 10 women showed local recurrences without negatively impacting survival. The recurrences included round/punctate, amorphous, fine pleomorphic, and fine linear or fine-linear branching descriptors. The breast cancer-specific long-term survival rate was 91/94 (96.8%) for a mean follow-up of 81.4 months. The 3 patients who died due to breast carcinoma showed fine pleomorphic calcifications, and had nodal-positive invasive carcinoma at diagnosis ...
The micrometastasis was discovered because your surgeon performed an axillary lymph node dissection. A surgeon typically performs a lymph node dissection for ductal carcinoma in situ (DCIS) when there is extensive DCIS (like you had) or when a patient has a high-grade DCIS. When DCIS is high-grade, there are many dead cells in the duct, and the cells that are alive are very aberrant. In this situation there is a higher chance that microinvasion-a spot where the DCIS has crossed the line to invasion-has occurred.. It can be tricky to diagnose micrometastases in the sentinel node. Most likely your micrometastasis is due to cells that were displaced during surgery as opposed to an actual spread of cancer cells from the DCIS, especially if there was no invasion outside the duct. However, the only way to know this for sure is to have an expert in breast pathology determine if it is truly micrometastasis or if it is a displaced cell. This is why it is very important that you get a second opinion from ...
To summarize data on long-term ipsilateral local recurrence (LR) and breast cancer death rate (BCDR) for patients with ductal carcinoma in situ (DCIS) who received different treatments. Systematic review and study-level meta-analysis of prospective (n = 5) and retrospective (n = 21) studies of patients with pure DCIS and with median or mean follow-up time of ≥10 years. Meta-regression was performed to assess and adjust for effects of potential confounders - the average age of women, period of initial treatment, and of bias - follow-up duration on recurrence- and death-rates in each treatment group. LR and BCDR rates by local treatment used were reported. Outside of randomized trials, remaining studies were likely to have tailored patient treatment according to the clinical situation. Nine thousand four hundred and four DCIS cases in 9391 patients with 10-year follow-up were included. The adjusted meta-regression LR rate for mastectomy was 2.6 % (95 % CI, 0.8-4.5); breast-conserving surgery with
In conclusion, Dr. Lori Pierce, Vice Provost for Academic and Faculty Affairs and Professor of Radiation Oncology at the University of Michigan, says this article has summarized nicely the major challenges facing breast cancer patients and their physicians in the management of ductal carcinoma in situ (DCIS). DCIS is not an invasive disease but can progress to invasive breast cancer, and potentially impact survival, in a significant number of women if not adequately treated when diagnosed. And we know that for those patients treated with lumpectomy, radiation to follow will reduce the chance of DCIS returning and/or invasive disease developing by at least 50%. We also know, however, that in some patients, the likelihood that DCIS will progress to invasive disease is very low even in the absence of treatment. Unfortunately, we have not found a reproducible way to predict those who need to be treated and those who dont but many researchers are working on this very question. For now, clinicians ...

A small, early study suggests that a shorter, higher-dose radiation schedule after lumpectomy to remove DCIS (ductal carcinoma in situ) may reduce the risk of the cancer coming back (recurrence) just as much as a standard radiation treatment schedule.. The study was published in the June 2012 issue of the International Journal of Radiation Oncology*Biology*Physics. Read the abstract of Five Year Outcome of 145 Patients With Ductal Carcinoma In Situ (DCIS) After Accelerated Breast Radiotherapy.. DCIS is the most common form of non-invasive breast cancer. DCIS is called non-invasive because it hasnt spread beyond the milk duct into any normal surrounding breast tissue. DCIS isnt life-threatening, but having DCIS can increase the risk of developing an invasive breast cancer later on. DCIS usually is treated with surgery to remove the cancer, lumpectomy in most cases. After surgery, many women have radiation therapy.. Radiation therapy after breast cancer surgery is most commonly given as 25 ...
Although a precursor to breast cancer, DCIS can progress to become invasive disease and thus is normally treated with surgery, sometimes in combination with radiotherapy.. The team of researcher behind this new work, based at the Netherlands Cancer Institute (The Netherlands), hope that their results may provide reassurance to those women diagnosed with DCIS. Overall the findings indicate that although these individuals have an increased risk of dying from breast cancer, they actually have a slightly lower risk of dying from any cause.. Under the instruction of Jelle Wesseling (Netherlands Cancer Institute), the team analyzed data from 10,000 Dutch women diagnosed with DCIS from 1989 to 2004. They tracked the data from these patients over an average 10-year period and compared mortality rates with the expected mortality of the general population.. In terms of breast cancer mortality risk, the study demonstrated that DCIS patients had a 2.5% risk of dying from breast cancer 10 years after ...
There are a few things about ductal carcinoma in situ (DCIS) on which everyone agrees: Incidence increased dramatically with the advent of mammography screening, not all cases detected will go on to cause symptoms in the patients lifetime, and theres no proven way to tell which cases will progress.. But agreement often ends when it comes to clinical management. Should all cases be treated with surgery and radiation in the absence of proven markers to show which cases will progress? Or is watch-and-wait an option? Can existing tools be used to guide the decision?. Experts put their views on the line in a debate at the 66th Annual Cancer Symposium of the Society of Surgical Oncology, held March 6-9 in Washington, DC.. Battle Lines Drawn. All DCIS patients benefit from standard therapy, declared Thomas B. Julian, MD, a Professor of Surgery at Drexel and Temple Universities in Philadelphia, who took the pro-treatment position in the debate-format session.. DCIS is a heterogeneous disease that is ...

Another interesting finding in our study is that women greater than 55 years of age with atypia had increased ER expression compared with younger women with atypia. This differs from the previous report by Shoker and colleagues (7) who found that ER expression was high in atypical ductal hyperplasia, ductal carcinoma in situ and lobular neoplasia regardless of age. The number of samples in that study was somewhat small; 23 cases of atypical hyperplasia, 43 cases of ductal carcinoma in situ, and 32 cases of lobular neoplasia. The authors suggested that in atypia and carcinoma in situ the regulation of ER expression may escape the normal age-related regulatory mechanisms. ER expression and relationship to age has also been studied in hyperplastic enlarged lobular units, a common alteration of the normal TDLU and potential precursor of breast cancer. Lee and colleagues (21) have shown that ER expression in hyperplastic enlarged lobular units is increased in postmenopausal woman compared with ...
Hollie Quinn suffered from the typical health complaints of an adult female; these included heartburn and acid reflux, along with painful cysts, vertigo and migraines.. Hollie says that she ate the typically American diet which was low in vegetables, high in sugar, and drank soda daily. She never questioned the health directives given to her by her doctors, and was never told that there might be a connection between her health issues and the diet that she was eating.. In 2002, when Hollie was just 27 years old and in her 38th week of pregnancy, she was diagnosed with an infiltrating ductal carcinoma. This is the most common type of breast cancer which affects some 80% of patients, and as its name suggests, the cancer had broken through the milk duct and was invading the surrounding tissues of the breast. Over time, invasive ductal carcinomas can spread to the lymph nodes and to other areas of the body. Hollies main tumor was 2.3 cm, with a second tumor measuring 0.6 cm. The larger tumor was a ...
AIM: The traditional architecture based classification system of ductal carcinoma in situ (DCIS) has been criticised on the grounds that individual lesions often show more than one pattern resulting in a large mixed category. New DCIS classification systems have emphasised the importance of cytological grade, which is reputed to be more uniformly expressed throughout a lesion. This study investigates the hypothesis that cytological heterogeneity is less common than architectural heterogeneity within DCIS lesions. METHODS: 121 cases of DCIS were graded as poorly, intermediately, or well differentiated according to a recently developed classification system that employs cytonuclear morphology as the major diagnostic criterion. Cases were categorised as pure when only one grade was present and as mixed if more than one grade was observed. Architecturally the cases were classified as solid, cribriform, micropapillary, or papillary and were described as pure if only one architectural pattern was ...
Here, we show that SOX11, an embryonic mammary marker that is normally silent in postnatal breast cells, is expressed in many oestrogen receptor-negative preinvasive ductal carcinoma in situ (DCIS) lesions. Mature mammary epithelial cells engineered to express SOX11 showed alterations in progenitor cell populations, including an expanded basal-like population with increased aldehyde dehydrogenase (ALDH) activity, and increased mammosphere-forming capacity. DCIS.com cells engineered to express SOX11 showed increased ALDH activity, which is a feature of cancer stem cells. The CD44+/CD24-/ALDH+ cell population was increased in DCIS.com cells that expressed SOX11. Upregulating SOX11 expression in DCIS.com cells led to increased invasive growth both in vitro and when they were injected intraductally in a mouse model of DCIS that recapitulates human disease. Invasive lesions formed sooner and tumour growth was augmented in vivo, suggesting that SOX11 contributes to the progression of DCIS to invasive ...

The differential expression of PDCD4 (in cancer cells) and miR-21 (in stromal cells) cannot alone form the basis for arguing that miR-21 is dynamically targeting PDCD4. Interestingly, we identified miR-21 in a subset of normal mammary glands and in some high-grade breast tumors - including pre-invasive DCIS lesions (ductal carcinoma in situ, considered the earliest form of breast cancer). We observed that miR-21 can indeed be expressed in normal epithelial and in cancer cells (Nielsen et al., 2014, Frontiers in Oncology ...
WILMINGTON, Del-AstraZen-eca announced in a news release that the FDA has approved Nolvadex (tamoxifen) to reduce the risk of invasive breast cancer in women with ductal carcinoma in situ (DCIS) following breast surgery and radiation. Nolvadex is the first medication to be approved for DCIS, which accounts for nearly 20% of all newly diagnosed breast cancers, the company said. 1
Most women usually opt for a lumpectomy with or without additional treatments such as for example radiation, hormonal therapy or chemotherapy. However, since the most DCIS lesions arent associated with formation of subsequent invasive tumors, chances are that many women identified as having DCIS are becoming over treated. Approximately 12-15 % of ladies diagnosed with DCIS create a subsequent invasive tumor within a decade after undergoing medical lumpectomy.

Investigating multiple samples (n={}25) from four patients we found an average of 5.6 ± 0.9 (mean ± SEM) chromosomal imbalances already present in DH. In the twelve DCIS lesions an average of 10.8 (±0.9) aberrations was identified with 14.8 (±0.8) aberrations in the four adjacent IDC lesions. The increasing number of chromosomal changes in parallel with the histopathological sequence corroborate the hypothesis, that the carcinomas may have developed through a sequential progression from normal to proliferative epithelium and eventually into carcinoma. However, heterogeneous results were identified in the multiple samples per entity from the same patient, demonstrated mainly in the DCIS samples in the chromosomal regions 6p, 9p, 11q, 16p and 17q, in the DH samples by 3p, 16p and 17q. This heterogeneous findings were most pronounced within the DH and was less in the DCIS and IDC samples. The only aberration consistently found in all samples - even in all DH samples - was amplification of the ...
