Summary

This study looks at new blood tests that might help doctors know if any cancer is left after surgery for colorectal cancer that has spread to the lining of the abdomen. Researchers will track certain substances in the blood before and after surgery in 58 adults. The goal is to understand how these markers change over time and if they can give a more accurate picture than current methods.
