简要总结
RATIONALE: Drugs used in chemotherapy, such as mitomycin, fluorouracil, and cisplatin, use different ways to stop tumor cells from dividing so they stop growing or die. Combining radiation therapy with chemotherapy may kill more tumor cells. It is not yet known whether radiation therapy and mitomycin are more effective when combined with fluorouracil or with cisplatin in treating anal cancer .
PURPOSE: This randomized phase II/III trial is studying how well giving radiation therapy and mitomycin together with fluorouracil works compared to radiation therapy, mitomycin, and cisplatin in treating patients with locally advanced anal cancer.
详细描述
OBJECTIVES:
Phase II
-
Primary
-
Compare the early clinical response (tumor response at 8 weeks) of patients with locally advanced anal cancer treated with radiotherapy with mitomycin and cisplatin vs mitomycin and fluorouracil.
-
Secondary
-
Compare the feasibility of these regimens in these patients.
-
Compare the acute toxicity of these regimens in these patients.
-
Compare patient compliance to these regimens.
