title: Composite resection with mandibulectomy in the treatment of posterolateral oral cavity and lateral oropharynx squamous cell carcinoma.
abstract: From 1972 to 1987, 403 patients underwent a composite resection consisting of segmental mandibulectomy and neck dissection for the treatment of bucco-pharynx squamous cell carcinoma (303 patients had postoperative radiotherapy [XRT], 29 patients had preoperative XRT, and 100 patients had tissue salvage performed after XRT). Of the 303 patients who received preoperative XRT, 32 were clinically staged T2, 149 were staged T3, and 122 were staged T4; 194 of the 303 patients were staged N0. In the 100 patients who experienced relapse and who required "salvage surgery," the restaging found 20 patients staged T2, 39 staged T3, and 41 staged T4; 73 of the 100 patients were staged N0. The patients' mean postoperative stay was 15 days for those who had prior surgery and 21 days for those who had salvage surgery. With a minimum follow-up of 5 years, locoregional recurrences and postoperative death occurred in 86 of 274 patients (31%) in whom surgery and postoperative XRT were performed; in 17 of 29 patients (59%) who had preoperative XRT performed; and in 61 of 100 patients (61%) who had salvage surgery performed. In addition, in terms of functional results, only 61% of patients (206) were able to maintain normal speech function, and only 23% (91) were able to maintain normal oral feeding. Of the 403 patients, the 5-year survival rates were 33% for the overall population, 42% for patients with postoperative XRT, 16% for patients in whom operation was performed after preoperative XRT, and 17% for patients who underwent salvage surgery.
