Epidemiology and Long‐term Survival in Acromegaly: <i>A Study of 166 Cases Diagnosed between 1955 and 1984</i>

Abstract

In 1985, a follow-up investigation was performed of all patients with acromegaly (n = 166, 89 women and 77 men) seen over a 30-year period (1955-1984) at our Endocrine Unit, referral centre for the western region of Sweden (population 1.5 million). At the end of 1984, the prevalence of the disease was 6.9 per 10(5) inhabitants, the average incidence per year was 3.3 per million people. Mean age at diagnosis was 46.3 years and at death (n = 62) 64.1 years. About one-third of the patients (50/153), in whom it had been possible to estimate the total duration of the disease, had survived for more than 25 years. Mortality was, however, increased compared to the normal population. The observed number of deaths from vascular and malignant disorders was 32 and 15, respectively, compared to the expected numbers 9.0 (p less than 0.001) and 5.6 (p less than 0.01).
