Capecitabine and Oxaliplatin or Standard Follow-Up Care in Treating Patients Who Have Undergone Surgery for Locally Advanced Rectal Cancer

Colorectal Cancer Clinical Trial

Official title: Chemotherapy or No Chemotherapy in Clear Margins After Neoadjuvant Chemoradiation in Locally Advanced Rectal Cancer. A Randomised Phase III Trial of Control Vs Capecitabine Plus Oxaliplatin [CHRONICLE]

Status Completed

Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy, such as capecitabine and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving combination chemotherapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether giving capecitabine together with oxaliplatin is more effective than standard follow-up care in treating rectal cancer that was removed by surgery.

PURPOSE: This randomized phase III trial is studying capecitabine and oxaliplatin to see how well they work compared with standard follow-up care in treating patients who have undergone surgery for locally advanced rectal cancer.

Clinical Trial Description

OBJECTIVES:

• Compare the efficacy of adjuvant chemotherapy comprising capecitabine and oxaliplatin vs standard follow-up care, in terms of disease-free and overall survival, in patients with clear margins after complete resection of locally advanced rectal cancer.

OUTLINE: This is an open-label, randomized, controlled, prospective, multicenter study. Patients are stratified according to surgeon and nodal status (node positive vs node negative vs unknown). Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients undergo standard follow up.

• Arm II: Patients receive oral capecitabine twice daily on days 1-14 and oxaliplatin IV over 2 hours on day 1. Treatment repeats every 3 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed every 3 months for 2 years, every 6 months for 5 years, and then annually thereafter.
