The prevalence of oral cancer in relation to the ethnic origin of Israeli Jews.
Smoking, alcohol, and familial background are considered major cofactors in the cause of oral cancer. The purpose of the present study was to determine the relationship between ethnic origin and oral cancer in the Israeli Jewish Population. Data were collected during the years 1970 to 1980 from 342 dental records of patients in Israeli hospitals. Results showed a male/female ratio of 2:1. Of 264 patients with clearly determined ethnic origin, 72% were Ashkenazi, 15% Sephardi, and 13% Eastern ethnic origin. The relative prevalence showed that the risk of the Ashkenazi group to develop oral cancer was at least twice as high as the other two ethnic groups. The increase in occurrence of oral cancer with age in each ethnic group was highly significant (p < 0.001). The most common type of malignancy was squamous cell carcinoma (95%) with 99% of this malignancy occurring in patients in their sixth and seventh decade. A significant (p < 0.02) relationship between site of involvement and ethnic origin was also noted. The tongue was the leading site in the Ashkenazi and Sephardi groups, whereas the lip and alveolar ridges were the most affected sites in the Eastern ethnic group.
