This landmark trial showed that advanced laryngeal cancer could be treated with chemotherapy followed by radiotherapy instead of total laryngectomy, with the same survival and preservation of the larynx in about two thirds of survivors.
Phase 3 trial of 332 patients with stage III to IV laryngeal squamous cell carcinoma randomised to induction cisplatin-fluorouracil followed by radiotherapy in responders (with surgery for non-responders or relapse) or total laryngectomy with postoperative radiotherapy.
Two-year survival was 68 percent in both arms and the larynx was preserved in 64 percent of surviving patients in the chemotherapy arm, with fewer distant metastases but more local recurrences.
Organ preservation became a legitimate goal in laryngeal cancer; RTOG 91-11 later refined the approach to concurrent chemoradiation.
