BACKGROUND: Circulating miRNAs are stable in body fluids and resembles their levels in cancer tissue/cells. They have been expressed in many cancers among them is breast cancer. Authors aimed to investigate the expression level of three circulating oncomiRNAs (miRNA-21, miRNA-222 and miRNA-373) in serum samples as a minimally non-invasive method for early detection of breast cancer, and study their relation with clinicopathological characters. METHODS: MiRNAs expression levels were determined using quantitative real-time polymerase chain reaction (qPCR) in serum samples from three groups: primary breast cancer patients (n = 137), benign breast lesion patients (n = 60), and healthy individuals as control group (n = 38)...

BACKGROUND: Paget's disease of the breast is rare, even more so when it occurs in a supernumerary breast since diagnosis is delayed due to lack of exploration and ignorance of the pathology of ectopic breast. Based on an original clinical case, we provide a clinical update concerning ectopic breast and ectopic carcinoma, including Paget's disease. PATIENTS AND METHODS: A 44-year-old woman had complained of pain in the area of her supernumerary breast for several months...

Introduction: Diagnosis of hepatocellular carcinoma (HCC) is considerably delayed, being frequently done in the non-curative stage of disease. The reason for delayed diagnosis is indolent course in early stages and/or unspecific symptoms indistinguishable from underlying cirrhosis. Hitherto methods used for screening of HCC have important limitations. TRIMprob is a non-invasive method, which showed utility in detection of cancers located in prostate, breast, or urinary bladder. Aim: To determine the diagnostic accuracy of TRIMprob in detecting HCC in cirrhotic liver...

A 76-year-old female underwent breast-conserving surgery of the right breast and sentinel lymph node biopsy for primary breast cancer. Three years later, mammography and ultrasonography showed a small nodule in the right breast. There was nothing abnormal in the left breast. Three months later, she complained of a huge and rapid growing mass in the left breast. Malignant cells were obtained on fine needle aspiration biopsy in the right breast tumor. But it was not possible to diagnose whether the left breast tumor was benign or malignant on fine needle aspiration biopsy and needle biopsy...

The Korean Breast Cancer Society (KBCS) has established a nationwide breast cancer database using an online registration program in 1996. The present study aimed to analyze the basic findings and trends of breast cancer in Korea in 2015 using the data provided by the Korea Central Cancer Registry and the KBCS. In 2015, a total of 22,550 patients were newly diagnosed with breast cancer, of which 3,331 were carcinoma in situ cases and 19,219 were invasive cancer cases. The incidence rate of breast cancer in Korea has steadily increased since the nationwide database was established, and the crude rate and age-standardized rate including that of carcinoma in situ , were 88...

Aim of the study: The arsenal of questions and answers about the minor cancer initiating cancer stem cell (CSC) population put responsible for cancer invasiveness and metastases, has left with an unsolved puzzle. Specific aims of a complex project were partly focused on revealing new biomarkers of cancer. We designed and set up novel techniques to facilitate the detection of cancerous cells. Materials and methods: As a novel approach, we investigated B cells infiltrating breast carcinomas and melanomas (TIL-B) in terms of their tumour antigen binding potential...

Malignant breast cancer remains a major health threat to women of all ages worldwide and epigenetic variations on DNA methylation have been widely reported in cancers of different types. We profiled DNA methylation with ERRBS (Enhanced Reduced Representation Bisulfite Sequencing) across four main stages of tumor progression in the MMTV-PyMT mouse model (hyperplasia, adenoma/mammary intraepithelial neoplasia, early carcinoma and late carcinoma), during which malignant transition occurs. We identified a large number of differentially methylated cytosines (DMCs) in tumors relative to age-matched normal mammary glands from FVB mice...

Conservative breast surgery followed by irradiation, often referred to as Breast conserving therapy (BCT), has replaced modified radical mastectomy for the treatment of early stage invasive breast cancer and ductal carcinoma in situ (DCIS). About 10% to 40% of the patients treated with BCT have poor cosmetic outcome results. Small tumours in large breasts can be successfully treated by lumpectomy and radiotherapy, with good cosmetic outcome. However when the tumour breast ratio is higher, the cosmetic outcome can be very disappointing...

The present study aimed to determine whether the expression of microRNA (miR)-10b was correlated with the molecular subtypes of early invasive ductal carcinoma of the breast. In situ hybridization was used to detect the expression of miR-10b in 193 patients diagnosed with early invasive ductal carcinoma. Immunohistochemistry was performed to evaluate the expression of estrogen receptor (ER)-α, progesterone receptor (PR) and human epidermal growth factor receptor-2 (Her-2). The positive expression rate of miR-10b in patients with early invasive ductal carcinoma with ER-α (+) or PR (+) was decreased compared with ER-α (-) or PR (-) patients (P<0...

Prostate-specific antigen (PSA) is a serine protease produced by epithelial prostatic cells and its main function is to liquefy seminal coagulum. Currently, PSA is a biomarker for the diagnosis and screening of prostate cancer and it was the first cancer biomarker approved by the FDA. The quantity and serum isoforms of male PSA, allows distinguishing between carcinoma and benign inflammatory disease of the prostate. Initially, it was thought that PSA was produced only by the prostate, and thus, a protein that was expressed exclusively in men...

Background: Mammalian cells express a single functional heparanase, an endoglycosidase that cleaves heparan sulfate and thereby promotes tumor metastasis, angiogenesis, and inflammation. Malignant mesothelioma is highly aggressive and has a poor prognosis because of the lack of markers for early diagnosis and resistance to conventional therapies. The purpose of this study was to elucidate the mode of action and biological significance of heparanase in mesothelioma and test the efficacy of heparanase inhibitors in the treatment of this malignancy...

BACKGROUND: We present updated features to a model developed by Dana-Farber investigators within the Cancer Intervention and Surveillance Modeling Network (CISNET). The initial model was developed to evaluate the impact of mammography screening strategies. METHODS: This major update includes the incorporation of ductal carcinoma in situ (DCIS) as part of the natural history of breast cancer. The updated model allows DCIS in the pre-clinical state to regress to undetectable early-stage DCIS, or to transition to invasive breast cancer, or to clinical DCIS...

PURPOSE: The current standard of care for women diagnosed with early stage breast cancer is breast-conserving surgery (BCS) followed by external beam radiation therapy, commonly delivered over 3-6 weeks. As an alternative, select patients can undergo intra-operative radiation therapy (IORT) at the time of BCT. This technique delivers a single fraction of radiation at the time of surgery, enabling patients to undergo both surgery and radiation in a single session. Our current study analyzed the value of incorporating breast MRI into the routine work-up of patients deemed eligible for IORT, to quantify the impact on patient eligibility and requirement for additional work-up...

Breast cancer is the second leading cause of cancer death among women. Its early diagnosis is extremely important to prevent avoidable deaths. However, malignancy assessment of tissue biopsies is complex and dependent on observer subjectivity. Moreover, hematoxylin and eosin (H&E)-stained histological images exhibit a highly variable appearance, even within the same malignancy level. In this paper, we propose a computer-aided diagnosis (CAD) tool for automated malignancy assessment of breast tissue samples based on the processing of histological images...

Predicting tumor growth and its response to therapy remains a major challenge in cancer research and strongly relies on tumor growth models. In this paper, we introduce, calibrate, and verify a novel image-driven reaction-diffusion model of avascular tumor growth. The model allows for proliferation, death and spread of tumor cells, and accounts for nutrient distribution and hypoxia. It is constrained by longitudinal time series of dynamic contrast-enhancement-MRI images. Tumor specific parameters are estimated from two early time points and used to predict the spatio-temporal evolution of the tumor volume and cell densities at later time points...

Lambert-Eaton myasthenic syndrome (LEMS) is most commonly associated with small cell lung carcinoma, while it is rarely associated with gynecological and breast carcinoma. We herein report a case of LEMS associated with synchronous double cancer, which was a combination of small cell carcinoma of the cervix and breast carcinoma. The early diagnosis and treatment of LEMS are important for achieving a good outcome. The possibility of accompanying paraneoplastic neurological syndrome must be sufficiently considered in gynecology and breast cancer patients...
