Active Surveillance or Surgery in Treating Participants with Rectal Cancer, OPTION Trial

Trial Status: active

This clinical trial compares how well active surveillance versus standard of care surgical management works in treating participants with rectal cancer. Active surveillance involves monitoring participants for additional tumor growth after receiving cancer treatment. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether deferring surgery after active surveillance and chemotherapy will work better in treating participants with rectal cancer.
