Watchful waiting approach for rectal cancer patients after therapy

Treatment of T2-T3/NO-N+ Adenocarcinoma of the Rectum by Neoadjuvant Chemotherapy (FOLFOX) Followed by Preoperative Chemo (Fluorouracil / Capecitabine)-Radio Therapy (CRT) With Watchful Waiting for Complete Responders

Phase 2 Interventional Henry Ford Health System · NCT05526079

This study is testing if a 'watchful waiting' approach can safely help rectal cancer patients who have responded well to treatment avoid surgery while still keeping their cancer under control and improving their quality of life.

What this trial studies

This clinical trial investigates the effectiveness of a 'watchful waiting' strategy for patients with rectal cancer who have achieved a complete or near-complete clinical response after neo-adjuvant chemotherapy. The study aims to determine if this non-operative management approach can maintain local control and overall survival while improving patients' quality of life. Participants will undergo standard care assessments and additional imaging tests, with costs waived by providers. The trial focuses on a small cohort of patients at higher risk for complications, offering radical resection only if tumor regrowth occurs.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with rectal invasive adenocarcinoma located within 4 cm of the anal verge and who have achieved a complete or near-complete clinical response after chemotherapy.

Not a fit: Patients with tumors larger than 4 cm from the anal verge or those with other forms of cancer may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could reduce the need for invasive surgeries and improve the quality of life for rectal cancer patients.

How similar studies have performed: While the concept of watchful waiting is established in other cancers, this specific approach in rectal cancer is novel and has not been extensively tested.
