Background: To explore a possible rela!onship among blood groups and the prognosis of breast cancer, this case- control study was carried out in Arak city, Arak province, Iran. Materials and Methods: One hundred and thirty four pa!ents with breast cancer were inves!gated. ABO blood groups were obtained from medical records. Mul!variate analyses were performed, including size of tumor, axilla...

background: phyllodes tumor (pt) of the breast in hispanic patients is more frequently reported with large tumors and with more borderline/malignant subtypes compared with other populations. the objective of this study was to describe characteristics of patients with pt and to identify differences among subtypes in a mexican population.  methods: a retrospective study was conducted on patients ...

PURPOSE The purpose of this study is to investigate the prognostic significance of tumor size for 5-year survival rate in patients with gastric cancer. MATERIALS AND METHODS A total of 1,697 patients with gastric cancer, who underwent potentially curative gastrectomy, were evaluated. Patients were divided into 4 groups as follows, according to the median size of early and advanced gastric can...

objective: breast cancer comprise approximately one third of malignant cases in women and is considered as the most common invasive condition in women at an age range of 15-54 years and as the second most prevalent cause of mortality at an age range of 55-74 years. tumor inhibiting factor p53 is a vital homeostatic regulator and its inactivation at the related gene or molecule could lead to tum...

Cancer stem cells (CSCs) are unique subpopulations that have the capacity to drive malignant progression with renewal abilities. Recently the role of some of CSCs in gastric adenocarcinoma has been studied. This study was performed in order to evaluate CD44 and CD133 expressions by immunohistochemistry in 95 primary gastric adenocarcinoma and their relation to clinical and pathological paramete...

Background: Microcystic adnexal tumor is a rare sclerosing variant of ductal carcinoma of eccrine sweat glands which is highly invasive. This tumor is often misdiagnosed as other benign or malignant skin lesions and improper treatment is carried on and is associated with high recurrence rate. Case presen...

Background & Objective: In vascular (vasculogenic) mimicry (VM), tumoral cells mimic the endothelial cells and form the extracellular matrix-rich tubular networks. It has been proposed that VM is more extensive in aggressive tumors. This study was designed to investigate the rate of VM expression in the stromal cells of invasive ductal carcinoma (IDC) and to find its relationsh...

although the majority of mesenchymal lesions of the gastrointestinal tract are neoplastic in nature, but nonneoplastic reactive processes may also involve the gastrointestinal tract and mesentery. some more aggressive neoplasms located in same area, such as fibromatosis or gastrointestinal stromal  tumors  may  be  cause  of  diagnostic  confusion.  reactive  nodular  fibrous  pseudo  tumor (rn...

Four non-small-cell lung cancer (NSCLC) registration trials were utilized to develop models linking survival to risk factors and changes in tumor size during treatment. The purpose was to leverage existing quantitative knowledge to facilitate future development of anti-NSCLC drugs. Eleven risk factors were screened using a Cox model. A mixed exponential decay and linear growth model was utilize...
