The Survival Rate of Patients with Colorectal Cancer in Yazd during 2001-2011

Colorectal cancer survival rate has increased due to the advances in this disease treatment in the recent years. Therefore, this study aimed to investigate the survival rate for colorectal cancer patients from 2001 to 2011 in Yazd. In this retrospective cohort study, 604 patients with colorectal cancer were studied who were admitted to the cancer registry of Yazd province from 2001 to 2011. Their death time was determined by the death registry center or their families. Those who died due to other reasons rather than this cancer were omitted. The data were analyzed by Kaplan-Meier method and x2. The mean age of these patients was 58.9±19.99 years and the median age was 62 years. Their survival rates in one, five and ten years were respectively 72.2 %, 50.1% and 39.8% regardless of their sex and age. The survival mean and median were 0.23±6.47 and 0.71±5 years. In this study there was a significant relationship between age and survival rate, though no significant relationship was observed between sex and survival. Moreover, the survival rate in patients younger than 50 years was significantly more than those older than 50 years. Despite advances in colorectal cancer treatment in Iran and around the world, in this study, the long-term survival rate was reported less than that of developed countries.
