Lateral pharyngotomy for selected invasive squamous cell carcinoma of the lateral oropharynx. Part II: When and why. Laryngoscope Laccourreye, O., Benito, J., Garcia, D., Menard, M., Bonfils, P., Holsinger, C. 2013; 123 (11): 2718-2722

Abstract

OBJECTIVES/HYPOTHESIS: To analyze local failure following lateral pharyngotomy for selected untreated invasive squamous cell carcinoma (SCC) of the lateral oropharynx. STUDY DESIGN: Retrospective review from a university teaching hospital. METHODS: Inception cohort of 91 patients who underwent lateral pharyngotomy for an isolated and previously untreated selected invasive carcinoma of the lateral oropharynx classified as T1 (26), T2 (47), T3 (11), and T4 (7). Induction chemotherapy, neck dissection, and postoperative radiation therapy were used in 91.2%, 94.5%, and 53.5% of patients. RESULTS: The 5-year Kaplan-Meier estimate of local failure was 16.6% for T1, 19% for T2, 38.6% for T3, and 16.7% for T4 lesions (P?=?.46). In a logistic regression model, only positive margins of resection statistically increased (P?=?.01) the risk for local failure. In patients with safe margins of resection, the 5-year Kaplan-Meier estimate of local failure was 5.6% for T1 lesions, 10.7% for T2 lesions, 23.8% for T3 lesions, and 20% for T4 lesions (P?=?.4). Local failure had a significant impact on increased nodal failure (P?=?.001) and on reduced survival (P?
