Rectal cancer treatment and survival--comparison of two 5-year time intervals.

In last two decades there was a huge step forward concerning rectal cancer treatment. The aim of our study was comparison of two time intervals regarding the methods of treatment and results of radical rectal cancer surgery. 407 patients operated on for rectal cancer were included in study. Those were patients with elective radical resection of solitary rectal tumor who survived first month after the operation. Patients were divided in two groups regarding the time of operation. In group one were patients operated on between 1996 and 2000 and in group two patients operated on between 2001 and 2005. We compared our results in both intervals with special interest about type of operation considering localization of the tumor, local recurrence and cancer related survival. Significant differences were found between two groups. There were more sphincter saving operations in second group, less local recurrences and better survival than in first group. This study observed significant improvements at recurrence rates and total survival for patients operated on rectal cancer.
