Background & Objectives : Gastric cancer has a low survival and remains a serious threat to the health of human life, especially in developing countries such as Iran. The present study was performed to estimate the main effective factors in the survival rate of patients with gastric cancer in the Province of Kohgilouyeh & Boyerahmad. Methods: All cases of gastric cancer in Kohgiloyeh and...
Background: Identification of correlated genes with survival by gene expression data is an important application of microarray data. The purpose of this study is to identify correlated genes with survival of conventional renal cell carcinoma (cRCC) patients based on gene expression profiles. Methods: This study is a survival analysis with high dimensional covariates and containing 14814 gene...
data utilized in this study were 6800 records of lambs’ life longevity, and survival rate from 263 sires and 1839 dams collected from 1989 through 2009, from the lori-bakhtiari flock at shooli station in shahrekord. the data were analyzed, using linear and hazard ratio models along with weibul function. these models included such non genetic factors as year and month of birth, sex of lamb, type...
In this investigation, the effect of seed source on the germination and survival of Acer velutinum Boiss. was assessed. Seeds were collected from 11 seed sources ( located at 20 to 2200 meter a.s.l in Mazandaran forests) and planted in a mountain nursery (Orimelk located at 1550 meter a.s.l) as completely randomized block design with three replications. The results show that the effect of seed ...

Spatial Varying Coefficient Regression Model For Relative Risk Factors of Esophageal Cancer Patients
In conventional methods for spatial survival data modeling, it is often assumed that the coefficients of explanatory variables in different regions have a constant effect on survival time. Usually, the spatial correlation of data through a random effect is also included in the model. But in many practical issues, the factors affecting survival time do not have the same effects in different regi...
background: today, despite the many advances in early detection of diseases, cancer patients have a poor prognosis and the survival rates in them are low. recently, microarray technologies have been used for gathering thousands data about the gene expression level of cancer cells. these types of data are the main indicators in survival prediction of cancer. this study highlights the improvement...
background: gastric cancer is the second leading cause of cancer death. the aim of this study was to determine the survival rate affected by risk factors in patients with gastric adenocarcinoma. methods: we performed this retrospective cohort study on patients diagnosed with gastric adenocarcinoma during 2005-2012 in hamadan, iran. all patients with pathological diagnosis enrolled in the study....
Introduction: Cancers are the second cause of death in the world after cardiovascular diseases. Cancer of the stomach is one of the most important forms of cancer worldwide. It is the fourth most common form of cancer and the second most common cause of death in the world. There is a wide variation in the survival of gastric cancer among and even within countries. In this study we seek to inves...
Introduction & Objective: Gastric cancer is the forth common cancer and second cause of death. Surgery is the primary treatment of gastric cancer and chemotherapy and radiotherapy is used as supplementary treatments. The aim of this study is estimation of survival and affected fac-tor in the patients with gastric cancer after surgery in Hamadan province. Materials & Methods: All patients with p...
