Background & Aim: Cancers are the second cause of death after cardiovascular diseases globally. Colorectal cancer is the third most prevalent cancer in the world. This cancer is the third leading cause of death in America and one of the most prevalent cancers of the gastrointestinal tract in Iran. The purpose of this study was to estimate the survival rate of patients with gastric cancer in Chaharmahal and Bakhtiari province, Iran.

Methods: The present observational (the analytical type) study was conducted using the longitudinal and survival study methods. The population study included all patients with gastric cancer in Chaharmahal and Bakhtiari province, Iran. The samples were selected by the census method and all the patients diagnosed with colorectal between the years 2000 to 2010 (estimated to be about 452 cases). After collecting the data and coding them, they were inserted into the SPSS 16 and STATA 12 software. To investigate the survival and the factors influencing the survival time of patients which was the main objective of this study, the Kaplan-Meier method was used. In order to compare the survival function in different subgroups, the log rank test or generalized Wilcoxon test was used.

Results: From the total 452 patients with colorectal cancer, 232 cases were male (51.3%) and 220 were females (48.7%), respectively. The mean age of patients was 59.12 ±19.99 years at the time of diagnosis. The median age of patients was 60 years. The probability of survival at 1, 5 and 10 years after diagnosis of colorectal cancer in both sexes using the Kaplan-Meier was 85.7%, 71.9,% 52.5% respectively.

Conclusion: Although the survival rate of patients with colorectal cancer in Chaharmahal and Bakhtiari province was at a desirable level, the need for further studies to identify prognostic factors is essential.
