Factors related to survival from oral cancer in an Andalusian population sample (Spain).

Abstract

Average survival was 2088 days, with a standard deviation of 98 days. The factors most associated with mortality were: location in the gingiva (p=0.0590), in the trigone (p=0.0104), size (T3-T4) (p=0.0004) and lymph node involvement (N2a-N2b) (p=0.0035). Tobacco and alcohol, nowadays considered to be highly significant in carcinogenesis, had no considerable influence on survival.
