Radiation before surgery for colorectal cancer: does it increase complications?

This study is looking at whether radiation therapy given before colorectal cancer surgery affects how many complications patients experience during and after their operation. Researchers want to compare two groups of patients — those who received radiation before surgery and those who did not — to see if there are meaningful differences in recovery problems, hospital stays, and other complications.

Radiation therapy before colorectal cancer surgery helps shrink tumors and improve the chances of successful surgery, but doctors aren't sure whether this treatment increases the risk of surgical complications, longer hospital stays, or slower recovery. This study aims to answer that important question so doctors can better prepare patients and manage their care.
