BACKGROUND: Squamous cell carcinoma (SCC) of the oral cavity occurs mainly in the male population. The objective of the study is to identify the main clinical and epidemiological differences of the oral SCC between men and women. METHODS: Retrospective analysis of the charts of 228 cases of SCC of the oral cavity in women treated at the Head & Neck Surgery Service, Heliopolis Hospital, São Paulo, Brazil from 1977 to 1996. The clinical and epidemiological characteristics of these cases were compared with those of 849 male patients. RESULTS: The mean age of women was 60.7 years (ranging 2 to 100 years) and in the male group was 55.6 years (p<0.00001). In cases where the alcohol intake and tobacco use were absent, the tumors ocurred in older patients. The isolated tobacco use didn't affect the distribuction by age but for the alcohol intake (alone or combined with tobacco) the patients were younger. On the alcohol intake, 71% of the women and 8% of the man used no alcohol. The most common sites of tumors were tongue and floor of the mouth but in the women group the incidence of tumors in these sites were 43% compared with 61% in the men. CONCLUSIONS: The highest incidence of SCC the of oral cavity occurs later in women, than in men. This could be explained by a lesser exposure to alcohol and tobacco in women. Other factors seem to be involved in this issue.
