Abstract

In order to compare the correlation of 1987 and 1997 UICC T categories with the survival rate in parotid gland carcinoma, 134 patients attending the ENT clinics at the University of Ferrara (from 1970 and 1993) and Firenze (from 1970 to 1990) were analyzed by means of survival analyses (Kaplan-Meier and Cox algorithms). This study demonstrated that both systems showed a significant correlation with the survival rate, but T 1997 resulted in a more reliable prognostic value by means of a higher odds ratio. We conclude that the newer (1997) UICC T category better defines the prognosis for cancer of the parotid gland and should have a higher impact on the clinical evaluation of patients
