CONVERT: Neoadjuvant Chemotherapy Alone Versus Preoperative Chemoradiation for Locally Advanced Rectal Cancer Patients

• Status: Active, not recruiting
• Trial end date: 2024-06-01
• Target enrollment: 0
• Participant gender: All

Summary

Although neoadjuvant radiotherapy greatly decreases local recurrence in locally advanced rectal cancer patients undergoing surgery, it inevitably results in short-term and long-term toxicities. More importantly, it has not been confirmed that neoadjuvant radiotherapy could improve overall survival. The purpose of this study is to compare the effects of chemotherapy alone using a combination regimen known as XELOX (capecitabine and oxaliplatin ) and selective use of the standard treatment to the standard treatment of chemotherapy and radiation.

• Phase: Phase 3
