- W2525295087 abstract "Objective. To analyze the possible prognostic factors for survival and disease-free survival in a group of patients with pri- mary malignant salivary gland tumors. Design. Seventy-five patients with salivary gland carcinomas were studied retrospectively from 1980 to 2003. All cases were initially treated with surgery. Posto- perative radiotherapy was applied in 52% of the patients. Survi- val and disease-free survival were analyzed with the Kaplan-Meier method. The association between the different prognostic factors and survival was studied with the Log Rank test for univariate analy- sis and the Cox proportional model for multivariate analysis. Results. The 5-year and 10-year crude survival rates were 74.9% and 63% and cause-specific survival rates were 77.7% and 65.3% respecti- vely. The 5-year and 10-year disease-free survival rates were 51.8% and 43.2%. Tumor location, sex, pathologic stage, tumor size, facial palsy, perineural spread and vascular spread showed statistical sig- nificance in survival and recurrence (p<0.05). Facial palsy and vas- cular spread were prognostic factors in the multivariate analysis. Conclusion. In our group of patients, facial palsy and vascular spre- ad are the most important factors for survival and recurrence. Pos- toperative radiotherapy does not appear to improve the prognosis of our patients." @default.
