Radiation Therapy, Cisplatin, Fluorouracil, and Cetuximab in Treating Patients With Locally Advanced Anal Cancer

• Status: Terminated
• Trial end date: 2010-11-26
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as fluorouracil and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving radiation therapy together with combination chemotherapy and cetuximab may kill more tumor cells.

PURPOSE: This phase II trial is studying giving radiation therapy together with cisplatin, fluorouracil, and cetuximab to see how well it works in treating patients with locally advanced anal cancer.

• Phase: Phase 2
