RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug or combining radiation therapy with chemotherapy may kill more tumor cells. It is not yet known whether fluorouracil and mitomycin plus radiation therapy is more effective than fluorouracil and cisplatin plus radiation therapy for anal cancer.
PURPOSE: This randomized phase III trial is studying fluorouracil and mitomycin plus radiation therapy to see how well it works compared to fluorouracil and cisplatin plus radiation therapy in treating patients with stage II or stage III anal cancer.
Further Study Information
- Compare the initial and total local and distant failure rates in patients with anal canal cancer treated with either fluorouracil (5-FU) plus mitomycin concurrently with radiotherapy or 5-FU plus cisplatin followed by 5-FU plus cisplatin concurrently with radiotherapy.
- Identify any differences in local control and colostomy rates at 2 years in patients treated with these regimens.
- Determine any difference in colostomy free, disease free, or overall survival in patients treated with these regimens.
- Compare the toxic effects of these regimens in these patients.
- Evaluate the prognostic effects of tumor markers P53 overexpression, human papilloma virus status, and enzyme HAP1 in patients treated with these regimens.
OUTLINE: This is a randomized study. Patients are stratified according to gender, nodal status (positive vs negative), and primary tumor size (greater than 2 cm to 5 cm vs greater than 5 cm). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive fluorouracil (5-FU) IV continuously over 96 hours beginning on days 1 and 29 and mitomycin IV on days 1 and 29 with concurrent radiotherapy.
- Arm II: Patients receive induction chemotherapy comprising 5-FU IV continuously over 96 hours beginning on days 1, 29, 57, and 85 and cisplatin IV over 1 hour on days 1, 29, 57, and 85. Beginning on day 57, patients receive concurrent radiotherapy.
In both arms, radiotherapy is administered daily, 5 days a week, for 5-6.5 weeks. Patients with T3, T4, or N+ lesions or T2 lesions with residual disease receive additional radiotherapy to a reduced field.
Patients are followed every 3 months for 1 year, every 6 months for 1 year, and then annually thereafter.
