PHASE II STUDY ON LARYNX PRESERVATION COMPARING INDUCTION CHEMOTHERAPY AND RADIOTHERAPY VERSUS ALTERNATING CHEMO-RADIOTHERAPY IN RESECTABLE HYPOPHARYNX AND LARYNX CANCERS

OBJECTIVES:

• Compare relapse-free survival and larynx preservation in patients with resectable hypopharyngeal or laryngeal cancer treated with sequential vs alternating cisplatin and fluorouracil and radiotherapy.
• Compare the health-related quality of life in patients treated with these regimens.
• Compare the cost-effectiveness of these regimens.

OUTLINE: This is a randomized, multicenter study. Patients are stratified by performance status, disease site, tumor stage, node stage, and center.

Patients are randomized to one of two treatment arms. Both groups may receive either conventional radiotherapy in single daily fractions, 5 days per week, for 7 weeks (option 1) or hyperfractionated radiotherapy in 2 daily fractions, 5 days per week, for 4-5 weeks (option 2), according to institutional policy.

• Arm I: Patients receive cisplatin and fluorouracil every 3 weeks. Patients with a complete or partial response on day 42 receive 2 additional courses of chemotherapy followed by 7 weeks of radiotherapy beginning on day 80. After radiotherapy, patients with a complete remission enter follow-up; those with a partial remission proceed to surgery. Patients with stable or progressive disease proceed immediately to surgery with or without postoperative radiotherapy.
• Arm II: Patients receive cisplatin and fluorouracil every 3 weeks for 4 courses. Patients treated on radiotherapy option 1 are evaluated 2 months after completion of radiotherapy; those with a complete remission enter follow-up while all others proceed to surgery. Patients treated on option 2 are evaluated on day 42; those with a partial or complete response complete chemoradiotherapy and are then evaluated and treated like option 1 patients. Patients with stable or progressive disease on day 42 proceed to surgery with or without a third course of chemotherapy on week 7.
