A decreasing incidence of ovarian carcinoma in Israel

The aim of the present study was to assess the incidence trend of invasive epithelial ovarian carcinoma in Israel. We assessed the incidence rate of invasive epithelial ovarian cancer in Israeli Jewish women during the 10-year period from 1993 to 2002 based on data obtained from the population-based Israel National Cancer Registry. There was a gradual significant decrease in the incidence of ovarian cancer from 9.64 in 1993 to 6.55 in 2002. The decrease in incidence was evident in all ethnic groups except those born in Asia and in all the age groups older than 35 years. The decrease in incidence of ovarian carcinoma is gratifying, but its reason remains obscure.
