Background & objectives: Competing risk data is one of the multivarite survival data. Competing risk data can be modelled using copula function. In this study we propose a bayesian modelling approach of competing risk data using the copula function.Methods: We used the data from colorectal cancer registyrarty in Tehran. After constructing likelihood function using Clayton copula by choosing app...
The stomach is a very rare location of metastatic deposits. We present case gastric deposit from primary colon cancer. Computed tomography (CT) indicated cancer, but also revealed the presence cancer in region greater curvature and antrum. With progression creation an extraluminal tumor mass, process progresses manner that transversal merges into located stomach. patient underwent subtotal gast...
Background and purpose: Binding a monoclonal antibody to tumor associated antigens is an effective method for cancer therapy because these agents can specifically target malignant cells. In fact, monoclonal antibodies are effective agents for diagnosis, grading and treatment of different kinds of cancers. In this research, a new monoclonal antibody against colon cancer cells was prepared and ...
Background: Population based research contributes to our understanding of cancer at many levels. For health program planning and policy making it is important to have information about the incidence of the common cancers in the population. Descriptive epidemiologic studies measure the occurrence of cancer and other health-related factors in relation to person (e.g. age, sex, race, social class,...
Background: Colorectal cancer is the fourth most common cancer, in terms of incidence throughout the world. There are some differences for risk factors involved in the incidence of tumor in different anatomical subsites of large bowel. However, most investigations have not studied the association between dietary factors and colorectal cancer subsites. Thus the current ecological study inves...
Background: Metastasis and recurrence of colorectal cancer after treatment is attributed to stem cells. The aim of this study was to determine the relationship between the expression of stem cell marker CD166 in colorectal cancer by immunohistochemistry and clinicopathologic parameters.Methods: From 2006 to 2012, 121 colectomy specimens of patients with colon cancer that were operated in Babol...
aim : the aim of this study was to compare prognostic factors between colon and rectal cancers. background : prognosis of colorectal cancer (crc) may depend on the anatomical site. patients and methods : a total of 1219 patients with crc diagnosis according to the pathology report of rcgld cancer registry, from 1 january 2002 to 1 october 2007, were entered into the study. demographic and clini...
Background and Objective: Dimethylhydrazine (DMH) is metabolized to methyldiazonium by cytochrome p450 (CYP 450) in liver that increases some oncogenes expression and via beta catenin mutation and prevention of its destruction. Materials and Methods: In this study, 48 rats were divided into 6 groups. Colon cancer was induced by DMH injection (20 mg/kg b.w.)(s.c.) once a week for 18 weeks. A...
objective(s):transforming growth factor-β(tgf-β) is involved in colorectal cancer (crc). the sd-208 acts as an anti-cancer agent in different malignancies via tgf-β signaling. this work aims to show the effect of manipulation of tgf-β signaling on some mirnas implicated in crc. materials and methods: we investigated the effects of sd-208 on sw-48, a colon adenocarcinoma cell line. the cell line...
Benign neoplasms of the colon, rectum, anus and anal canal are true neoplasia colon mucosa associated with a high risk colorectal cancer (CC). The literature review analyzes epidemiology, factors, modern methods diagnosis treatment, describes priority minimally invasive interventions for benign tumors.
