Conclusions:
Given that radiation therapy (RT) is currently initiated as soon as possible after surgery, our results indicate that the main prognostic factors of survival are pT and pN stages in patients treated with surgery and postoperative RT for locally advanced head and neck squamous cell carcinoma (HNSCC).

Objectives:
To determine the prognostic factors for survival in patients treated with surgery and postoperative RT for locally advanced HNSCC. Patients and methods. A retrospective study was performed on 308 consecutive patients treated from 1990 to 1998 with surgery and postoperative RT. In addition to histological factors, time-related factors were considered.

Results:
The median age of the whole cohort was 56 years (range 35-83). Median follow-up was 98 months. Median interval from surgery to the start of RT was 44 days (range 18-157), while median RT duration was 52 days (range 22-115). From univariate analysis of overall survival, statistically significant prognostic factors were pT stage (p<0.0001), pN stage (p=0.008), RT duration (p=0.01) and total treatment time (p=0.02). Perineural invasion, perivascular invasion, extranodal spread and positive resection margins did not appear to be related to survival. From multivariate analysis, the only statistically independent prognostic factors appeared to be pT and pN stages.
