Adenocarcinoma of the uterine cervix in Jewish women: a distinct epidemiological entity.

During an 11-year period, 532 Jewish women with invasive cancer of the uterine cervix were diagnosed in Israel. Of these, 441 (82.9%) had squamous cell carcinoma (SUC) and 52 (9.8%) had adenocarcinoma (AUC). Different characteristics were noted for these two histological categories with regard to age, ethnic distribution, and chronological time trends. The ratio between AUC and SUC differed considerably between the various ethnic groups, ranging from about 1:6 in the Asian and European born to less than 1:14 in the North African. This indicates that the relatively higher incidence of AUC in Israeli Jewish women is limited to those ethnic groups that have a low risk for cervical cancer. The different patterns of SUC and AUC in the population support the contention of a varying etiology.
