Background and Objective: Breast cancer is the most common cancer and the major cause of cancer death among women. The survival rate for breast cancer indicates the percentage of people that survive the disease for a specified period of time after diagnosis. The aim of this study was analyzing the survival rate of patients with breast cancer in East Azarbaijan province. Materials and Methods...
background: toxoplasmosis is considered as one of the most common infectious diseases caused by the protozoan parasite toxoplasma gondii . tachyzoite is the main form of toxoplasma and continuously is maintained in cell culture or injected into the mice peritoneal cavity. this study was designed to evaluate the survival rate of rh strain of t. gondii tachyzoites in different cell free, nutrient...
Background and purpose: Hypoxia occurs especially in heart diseases and could lead to death. Compounds with antioxidant activity could display antihypoxic property. Sambucus ebulus (SE) and Myrtus communis (Myrtle) are well known plants with distinctive antioxidant activities. To the best of our knowledge there are no reports on their antihypoxic activities. Materials and methods: Protective e...
background : gastric cancer is the one of the most prevalent reason of cancer-related death in the world. survival of patients after surgery involves identifying risk factors. there are various models to detect the effect of risk factors on patients’ survival. the present study aims at evaluating these models. methods : data from 330 gastric cancer patients diagnosed at the iran cancer institut...
conclusions parametric models may provide complementary data for clinicians and researchers about how risks vary over time. the weibull model seemed to show the best fit among the parametric models of the survival of hemodialysis patients. results the results of a multivariate analysis of the variables in the parametric models showed that the mean serum albumin and the clinic attended were the ...
Background: Small cell lung cancer (SCLC) is a highly aggressive tumor. Objective: To evaluate the survival and time to progression of patients with SCLC admitted to a chest disease center in Istanbul, Turkey. Methods: Based on the reports of a pulmonary oncology clinic, data regarding performance status (PS), clinical stage of disease, treatment, time to progression and survival of 67 patients...
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...
ABSTRACT Neuroblastoma is a tumor with neural cells origin. It usually originated from adrenal gland and sympathetic ganglions. This tumor is the most common tumor in infants and is in forth grade amonge tumors in childhood. In this reaserch we determine to study the prognostic factors in survival of children with neuroblastoma.This is an analytic cross- sectional reaserch on 119 ...
