Abstract

Background: 4cure models are a model to analyze survival data that these models exist for long term survivors. Cure models are a special type of survival model where it is assumed that there are a proportion of subjects who had never event, thus, survival curve will eventually reach a plateau. Therefore, standard survival models are not appropriate because they do not account for the possibility of cure.The aim of the present research is to apply NON-MIXTURE CURE MODEL to analyze survival of patients with COLORECTAL CANCER.Materials and Methods: We studied 232 patients with COLORECTAL CANCER who were visited and treated at Taleghani Hospital Research Center for Gastroenterology and Liver Disease in Tehran. These patients were diagnosed from 1987 to 2012 and followed up until 2013. The Effect of age, gender, family history, body mass index and site of infection were studied. Kaplan-Meier and NON-MIXTURE CURE MODEL were used for analzing data.Results: The ten- year survival rate after diagnosis in the studied patients was 64 % .A total of 60 (25.8 %) deaths due to COLORECTAL CANCER were observed. The mean of age at the time of diagnosis was 51.6 years. Based on non-mixed cure model, the rangs of age was 45-65 years old and BMI were significant.Conclusion: When the population is divided into two groups (susceptible and non- susceptible individuals), using Cox semi-parametric model is not appropriate. Therefore, we should use cure models.
