NCT ID NCT04864067

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested a treatment plan for locally advanced rectal cancer that uses a short course of radiation followed by chemotherapy, aiming to avoid surgery. 39 patients were enrolled. The goal was to see if the cancer could be completely controlled without an operation, using a 'watch and wait' approach for those who responded well. The study measured how many patients had a complete response lasting more than a year.

What this could lead to

If successful, this approach could allow some patients with locally advanced rectal cancer to avoid major surgery and its side effects, while still controlling the disease.

What could go wrong

This is a small, single-arm Phase 2 trial with only 39 participants, so results may not apply to everyone. The long-term safety and effectiveness compared to standard treatment are not yet proven.
