Total Neoadjuvant Therapy With Additional Consolidation Chemotherapy Followed by Local Excision Versus Total Neoadjuvant Therapy Followed by Local Excision at Stage I Rectal Cancer (OPTION)
Safety and Efficacy of Organ Preservation Treatment for Stage I Rectal Cancer: Optimization of Consolidation Chemotherapy Before Local Excision After Neoadjuvant Chemoradiotherapy (OPTION); A Multi-center, Prospective, Randomized Trial
Safety and Efficacy of Organ Preservation Treatment for Stage I Rectal Cancer: Optimization of Consolidation Chemotherapy Before Local Excision After Neoadjuvant Chemoradiotherapy (OPTION); A Multi-center, Prospective, Randomized Trial
The goal of this clinical trial is to find out if adding consolidation chemotherapy with capecitabine after total neoadjuvant chemoradiotherapy (TNT) works to improve oncologic outcomes in patients with stage I rectal cancer. It will also comparethe safety of adding consolidation chemotherapy before local excision.
The main questions it aims to answer are:
- Does adding consolidation chemotherapy increase the rate of pathologic complete response?
- What medical problems or side effects do participants have during and after treatment?
Researchers will compare TNT followed by local excision to TNT followed by consolidation chemotherapy with capecitabine and then local excision to see if adding consolidation chemotherapy improves tumor response and treatment outcomes.
Participants will:
- Receive TNT for stage I rectal cancer
- Be randomly assigned to one of two treatment groups
- Undergo local excision after preoperative treatment
- Visit the clinic for checkups and tests to evaluate tumor response, side effects, recurrence, survival, quality of life, bowel function, urinary function, sexual function, circulating tumor DNA, and treatment-related costs
