Carcinoma of the head and neck: a 5- to 20-year experience with preoperative chemotherapy, uncompromised surgery, and selective radiotherapy.
BACKGROUND: A 5- to 20-year evaluation of preoperative chemotherapy uncompromised surgery and selective radiotherapy in stage III/IV head and neck squamous cell carcinoma. METHODS: Eighty-two consecutive patients, single surgeon previously untreated, operable, and resectable for cure. Sites included the oral cavity, oropharynx, larynx, and hypopharynx. Two chemotherapeutic regimens were used: initial regimen (A), cisplatin/bleomycin (n = 45 patients); revised regimen (B), cisplatin/5-fluorouracil (n = 37 patients). The extent of surgery was carefully documented before chemotherapy-tattoo when feasible. This forms a strict guide for uncompromised surgery. Selective postoperative radiotherapy was based on specific criteria. RESULTS: Minimum follow-up was 5 years. Absolute survival: total group, 60%; regimen A, 46%; and regimen B, 77% (P =.004). Relative survival (correcting for life table mortality): total group, 66%; regimen A, 50%; and regimen B, 83% (P =.003). Recurrences: primary site, n = 9 (regimen A, n = 7 [16%]; regimen B, n =2 [5%]) and neck, n = 6 (13%, all in regimen A). Distant metastasis occurred in 12 patients (10 [22%] in regimen A and 2 [5%] in regimen B). CONCLUSIONS: This study suggests treatment of advanced head and neck squamous cell carcinoma (resectable for cure) with preoperative chemotherapy (regimen B); resection of original tumor volume, regardless of response to chemotherapy; and selective (rather than routine) postoperative radiotherapy results in improved survival. More controlled studies are recommended.
