Abstract
PURPOSE: To compare the correlation of TANIS and TNM '97 with the survival rate in laryngeal cancer. METHODS AND MATERIAL: From 1970 to 1990, 599 patients at the ENT Clinic, Un iversity of Ferrara, had a complete follow-up and met the criteria of enrol lment. Data were analyzed by means of survival analyses (Kaplan-Meier and C ox algorithms). RESULTS: Both systems showed a significant correlation with the survival ra te. TANIS advanced subcategories were better correlated with the mortality rate than TNM stages IVa and IVb, Again, in the final statistical model, TA NIS was more highly correlated with survival rate than TNM.
