CONTEXT: Acromegaly is usually due to the excessive secretion of GH by a pituitary adenoma. It is frequently accompanied by comorbidities that compromise quality of life and results in elevated mortality rates. OBJECTIVE: To evaluate mortality and morbidity in patients with acromegaly receiving multimodal care. SETTING: Tertiary care center. DESIGN, PATIENTS, AND METHODS: Retrospective evaluation of 442 patients (65.4% women; mean age, 43.5 ± 13.1 y) followed for a median of 6 years (interquartile range [IQR], 3-10). RESULTS: Twenty-two patients died during the study period (4.9%), representing a total standardized mortality ratio (SMR) of 0.72 (95% confidence interval [CI], 0.41-1.03). Standardized mortality ratios were 1.5 and 0.44 for patients whose last GH was above and below 2.5 ng/mL, respectively; 1.17 and 0.16 for those whose last GH was above and below 1 ng/mL, respectively; and 0.94 and 0.46 for those whose last IGF-1 was above and below 1.2 times the upper limit of normal (ULN), respectively. The prevalence of diabetes mellitus, hypertension, heart disease, and cancer was 30%, 35%, 8%, and 4.7%, respectively. The most common cause of death was cancer. On multivariate analysis, diabetes, heart disease, and cancer were related to a baseline GH > 10 ng/mL; the presence of cancer and the last IGF-1 were significant predictors of mortality. Survival decreased as the latest GH levels increased from < 1 ng/mL to > 5 ng/mL and as IGF-1 increased from < 1.2 to > 2 times the ULN. CONCLUSIONS: Mortality in acromegaly can be successfully reduced, provided patients are treated using a multimodal approach with careful management of comorbidities.
