Abstract
A possible rising incidence of malignant germ cell tumours in young women.
Highlights
Germ cell tumours comprise 95 percent of malignant testicular tumours but less than two percent of malignant ovarian tumours (Teilum, 1976; Weiss et al, 1977)
Cancer Surveillance Program (CSP) case ascertainment is currently complete for the 10 year period 1972-1981, during which time over 95 percent of Los Angeles County incident cases have been registered
Sizeable increases in the incidence of malignant germ cell tumours of both histologic types occurred in the 15-34 age range in both sexes between the two 5-year calendar periods (1972-76 and 1977-81)
Summary
Sizeable increases in the incidence of malignant germ cell tumours of both histologic types occurred in the 15-34 age range in both sexes between the two 5-year calendar periods (1972-76 and 1977-81). These trends are statistically significant in the 25-34 age group for both males and females. We compared the secular trends for the ovarian tumours (of both histologic types combined) in Los Angeles with data obtained from the Surveillance, Epidemiology, and End Results (SEER) Program, a series of population based tumour registries covering 10 percent of the total U.S population (Young, 1983 personal communication).
