Surgical management of early-stage hypopharyngeal carcinoma.

Abstract

There is little consensus regarding the extent of surgical ablation that is needed to attain cure in early-stage hypopharyngeal carcinoma (HPC). To determine effective surgical management of early-stage HPC, we retrospectively reviewed all cases of stage I or stage II HPC treated at our institution between 1970 and 1992. Of 305 patients identified with HPC, 50 (16%) had stage I (N = 13) or stage II (N = 37) cancer at diagnosis. Thirty-seven of the 50 (74%) underwent surgery alone or combined with preoperative or postoperative radiotherapy (RT). Patients were divided into three surgical groups. Group 1 underwent partial pharyngectomy (N = 9), group 2 underwent total laryngectomy and partial pharyngectomy (N = 17), and group 3 underwent total laryngopharyngectomy with cervical esophagectomy and reconstruction (N = 11). Overall and disease-specific survivals were determined from Kaplan-Meier survival analysis. Disease-free 5-year survival in stage I and II HPCs was 40.1%. Univariate analysis showed a statistically significant decrease in survival for patients undergoing partial pharyngectomy when compared with those undergoing more extensive procedures (p < .03). This was confirmed with multivariate loglogistic regression analysis (p < .03) correcting for confounding variables of site and RT. These data suggest that wide resection improves disease-free survival in patients with early-stage HPC.
