title: Long-term survival in malignant melanoma with special reference to age and sex as prognostic factors.
abstract: A total of 12,353 (97.5%) of all patients with a first malignant melanoma newly diagnosed in Sweden during the period 1960-82 were subjected to a complete computerized follow-up with respect to survival through December 31, 1982. Calculation of relative survival rates (RSs) revealed a consistently more favorable course in women than in men, the 5-year RSs being 80.8 and 68.0% and the 10-year RSs being 75.0 and 61.8%, respectively. Prolonged follow-up and analyses of annual excess mortality showed, in addition, that men surviving about 10 years constituted an apparently cured fraction, whereas among women there was an excess mortality throughout the observation period. The prognosis was increasingly more favorable at younger ages in males, whereas no regular age trend emerged in the female group of patients. A multivariate analysis indicated that the findings were not confounded by temporal trends in RSs or by differences in tumor location between the groups compared and also that the relative hazard was significantly higher for men than for women only during the first 8 years after diagnosis.
