Abstract

Cases of squamous cell carcinoma of the maxillary sinus initially treated at Keio University Hospital between January 1981 and December 1998 studied retrospectively involved 60 untreated cases - 46 men and 14 women aged 36 to 86 years (mean: 59.8 years). Of these, 7 had T2, 41 T3 and 12 T4 tumors based on 1997 AJCC TNM classification. Seven (11.7%) had nodal involvement but none had distant metastasis at diagnosis. Of the 60, 53 (88.3%) were stage III or IV. Prognostic factors and survival were statistically analyzed for 59 cases, excluding the 60th who died of another cause. Follow-up was 4 to 227 months, with a median of 59 months and a mean of 38 months. Of the 59, 48 (81.4%) underwent neoadjuvant chemotherapy (NAC). Survival was estimated using the Kaplan-Meier method as univariate analysis. Cause-specific 5-year survival was 56.8% for all stages, 68.2% for T2, 60.0% for T3, and 41.7% for T4. T stage classification was thus a significant independent prognostic factor in multivariate analysis using Cox's proportional hazards model (p= 0.0240). It also identified T stage classification (p=00486) and NAC (p=0.0419) as significant independent factors affecting survival with organ preservation. We also statistically analyzed 48 cases treated with NAC, which showed complete response (CR) for 11, partial response (PR) for 25. no change (NC) for 11, and progressive disease (PD) for 1. Responders (CR+PR) showed significantly better survival and organ preservation than nonresponders (NC+PD). The NAC response enables us to predict prognosis. T4 cases without NAC response should be treated intensively.
