简要总结
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known if surgery plus radiation therapy is more effective with or without chemotherapy for treating mouth cancer.
PURPOSE: Randomized phase III trial to compare the effectiveness of surgery and radiation therapy with or without chemotherapy in treating patients with stage II, stage III, or stage IV mouth cancer.
详细描述
OBJECTIVES: I. Assess the short- and long-term local control rates, disease-free survival, and overall survival following treatment with neoadjuvant cisplatin plus fluorouracil followed by surgery with or without radiotherapy vs surgery alone with or without radiotherapy in patients with previously untreated stage II-IV squamous cell carcinoma of the oral cavity. II. Assess the prognostic significance of clinical and pathologic responses to neoadjuvant chemotherapy in these patients. III. Compare the short- and long-term toxic effects of these two regimens.
OUTLINE: This is a randomized, multicenter study. Patients are stratified by center and nodal status (N0 vs N1-2 vs N3). Patients are randomized to one of two treatment arms. Arm I: Patients receive cisplatin IV on day 1 and fluorouracil IV continuously on days 1-5. Treatment repeats every 3 weeks for 2 courses in the absence of disease progression or unacceptable toxicity. Patients with stable disease after 2 courses or progressive disease at any time proceed to surgery. Patients undergo resection of the primary tumor site and possible nodal dissection no sooner than 2 weeks after completion of chemotherapy. Patients then undergo radiotherapy over 5-6 weeks no later than 8 weeks after surgery. Arm II: Patients undergo surgery and radiotherapy as in arm I. Patients are followed every 3 months for 1 year, every 6 months for 2 years, and then yearly thereafter.
PROJECTED ACCRUAL: A total of 240 patients will be accrued for this study over 9 years.
