Estimating the Net Survival of Patients with Gastric Cancer in Iran in a Relative Survival Framework
Background: Iran is an Eastern Mediterranean region country with the highest rate of gastric cancer. The present study aimed to evaluate the 5-year net survival of patients with gastric cancer in Iran using a relative survival framework.Methods: In a cross-sectional study, using life-table estimation of relative survival, we reported 1- to 5-year relative survival regarding age, sex, disease st...
An important issue in survival data analysis is the identification of risk factors. Some of these factors are identifiable and explainable by presence of some covariates in the Cox proportional hazard model, while the others are unidentifiable or even immeasurable. Spatial correlation of censored survival data is one of these sources that are rarely considered in the literatures. In this paper,...
Background & Objectives: Peritoneal dialysis is one of the most common types of dialysis in patients with renal failure. However multivariate analysis such as log- rank test and Cox have usually used to evaluate association of risk factors in survival of this group of patients, the aim of this study was to perform of Weibull, Gamma, Lognormal and Logistic Mixture cure models in survival an...

Introduction: There is a lack of information on the extent of dependency between chronic diseases and the survival rate of breast cancer. Until date, none of the models proposed has determined the impact of chronic diseases on breast cancer survival. This study, therefore, aimed to investigate the impacts of chronic diseases such as diabetes, blood pressure, and endocrine di...

Low survival of newborn seahorses hindered studies on the early life stage. Many important aspects contributing to the survival of newborn seahorses remained unknown. More research on juvenile stage is necessary to optimize the culture protocols. Stocking density may or may not affect fish growth and behavior. Effect of stocking density on the growth and survival of seahorses in the early stage...
Background and Aim: Glioblastoma multiforme (GBM) is the most common malignant and invasive tumor of the brain. The relation between prognosis and survival of GBM patients with Epidermal Growth Factor Receptor (EGFR) expression is challenging. Thus, we aimed to evaluate the prognosis and survival of patients with GBM and its relationship with EGFR expression. Materials and Methods: This single...
Aplastic anemia is a clinical syndrome in which there is peripheral blood pancytopenia due to reduced or absent production of blood cells without evidence of another marrow disorder. The disorder may be acquired or inherited like Fanconi’s anemia. In this study, survial and prognostic factors in acquired aplastic anemia is determined. This analytic cross-sectional study was done on 224 ...
Abstract Background and Objectives Evaluation of cell survival is important in cellular studies and the result is decisive for the application of the test substance. Different methods are used to evaluate cell survival and the correlation between methods is important. Here, Vero cell line was used to evaluate the effects of HSV-1 virus on cell survival. Cell survival after HSV-1 infection usin...
