Background and Aim: Breast cancer is an increasingly important social problem throughout the world. Rate of disease-free survival can be used to evaluate the effects of treatment and disease outcome and assess indices of disease prevention, diagnosis and treatment. With this aim in mind we made an assessment of 5-year disease-free survival in breast cancer patients. Material and Methods: 403 br...
Background and Objectives: Colorectal cancer is the fourth leading cause of cancer death worldwide. Annually 1430000 cases would be diagnosed and half of these people would die of the disease. In Iran, colorectal cancer is the fifth common cancer among men and is the thirdamong women. This study was designed to estimate survival rates for patients with colorectal cancer and related factors. ...
Introduction: The hypoxic state, in which experimental animals were subjected to an atmosphere of 5% O2 and %95 N2, has been used to screen agents for possible cerebral protection by measuring their ability to prolong survival time in mice exposed to hypoxia. Researchers showed that rimonabant and AM251 allosteric potentiate all but the β1 subunit containing GABAA receptors at nM...
average 1 1/2 ± SEM; normal t 1/2 3.7 ± 0.03 days) in 88 out of 128 (69%) men with coronary disease. In 35 out of 47 men with hyperprebetalipoproteinemia, SURV was shortened (3 ± 0.09 days) (74%). Of30 men with hyperbetalipoproteinemia, SURV was shortened (2.5 ± 0.10 days) in 26 (87%). Of 51 men without hyperlipoproteinemia, SURV was normal (3.3 ± 0.10 days) in 24 (47%). Dietary alteration of s...
Abstract: Background and purpose: The survival rate of gastric cancer patients has significantly increased during the last decades because of the advances in this type of cancer treatment. The purpose of the current study was to examine the survival levels of gastric cancer through Weibull regression and its affective causes. Materials and methods: In this research, the records and person...
Background and purpose: One of the most common methods used to estimate the effects of explanatory variables on survival time, is Cox semi parametric model. However, under certain circumstances, accelerated failure time parametric models are superior to the Cox model. The purpose of this study was to assess the efficiency of parametric and semi-parametric models in survival analysis of patients...
