The Epidemiology of Malignant Neoplasms of the Ovary, Fallopian Tube, and Broad Ligament in Canada: 1950-1984

Canadian patterns of incidence and mortality from malignancies of the ovary, fallopian tube, and broad ligament during the periods 1970-1980 and 1950-1984, respectively, were examined. Incidence rates during 1970-1980 remained stable at about ten new cases per 100,000 population per year. Analysis of age-specific rates demonstrated no significant changes in incidence for the eight age groups studied (P greater than .10). Although age-standardized mortality rates have not changed significantly during 1950-1984 (P = .61), four of the eight age groups studied (0-24, 25-34, 35-44, and 45-54) showed significant declines, whereas three other age groups (65-74, 75-84, and 85 and above) experienced significant rates of increase (P less than .025). Rates of increase for women aged 85 and over--0.94 additional new deaths per 100,000 population per year--were the most dramatic of any of the eight age groups studied.
