Summary
This study looked at daily patterns of natural chemicals in urine from 32 people with advanced colorectal cancer and healthy volunteers. Researchers collected multiple urine samples over two days to measure these chemicals, along with a saliva sample to check clock genes. The goal was to understand how cancer affects the body's internal rhythms, not to provide treatment.
