Survival and causes of death after adrenalectomy for Cushing's disease.
A consecutive series of 79 patients with Cushing's disease, treated by bilateral adrenalectomy (subtotal, total initially, or total finally) between 1953 and 1980, were studied to determine the survival and mortality rates and causes of death as long as 28 years after surgery. There were three early postoperative deaths, the last in 1974, caused by coma of unknown cause, severe diarrhea, and pulmonary embolism, respectively. The actuarial survival rates at intervals of 1, 2, 3, 5, 10, 15, and 20 years after surgery were approximately 87%, 83%, 82%, 79%, 72%, 68%, and 62%, respectively. These are significantly less than the rates for the general population (p less than 0.001). There were no differences between the sexes or between the types of operation (p greater than 0.05). The commonest causes of death were cardiac or vascular lesions (11 patients) and the local effects of pituitary tumors (four patients). These long-term results of an established method of treatment provide a standard by which other, especially newer, methods may be compared.
