Overview

abstract

  • BACKGROUND: The aims of this study were to determine the trends in survival of patients with anterior skull base cancer over several decades and to identify time-related changes in the demographic and clinical characteristics of this population. METHODS: In all, 282 patients who underwent craniofacial resection at Memorial Sloan-Kettering Cancer Center and Tel Aviv Medical Center were studied. Patients were categorized in accord with the period of surgery: early (1973-1984, n = 34), intermediate (1985-1996, n = 72), and later (1997-2008, n = 176). RESULTS: Patients operated after 1996 had higher rates of comorbidity, dural and pterygopalatine invasion, and multicompartmental involvement than those operated before 1996 (p ≤ .001). There was a significant improvement in 5-year overall and disease-specific survival, from 55% and 57%, respectively, for patients operated before 1996, to 66% and 70%, respectively, for those operated after 1996 (p = .02 and p = .006, respectively). On multivariate analysis, surgery after 1996 was an independent predictor of outcome (HR, 0.39, p < .001). CONCLUSIONS: The survival of patients with anterior skull base cancer is improving. Surgery after 1996 is an independent prognostic factor for an improved outcome.
