    Abstract:
    Because of the common belief that there is an increase in surgical risk and morbidity involved in the surgical therapy of elderly patients with acromegaly, physicians tend to either neglect therapy altogether or choose radiation therapy combined with medical treatment. In consideration of the expected increasing number of elderly patients resulting from social structure change in the coming years, we decided to investigate the outcome in 15 patients with acromegaly (13 women and 2 men) older than 64 years (mean, 68.3 yr) at the time of surgery in the form of a retrospective study. Medical treatment using either dopamine agonists (9 patients) and/or octreotide (4 patients) were attempted in 11 patients. For various reasons, however, medical therapy could not be permanently continued in any of these patients. The mean preoperative growth hormone (GH)-plasma level without medical treatment was 47.4 +/- 64.2 (mean +/- standard deviation) micrograms/L. At the time of operation, 13 of 15 patients had additional diseases, which led to an increased anesthesiological risk. Transnasal tumor removal was performed without anesthesiological or surgical complications in all patients. The radicality of tumor removal was controlled intraoperatively by GH measurements in eight patients. There was no postoperative mortality or serious morbidity. Postoperative basal GH-plasma levels were normal (< 4.5 micrograms/L) in all patients. None of the 13 patients who participated in long-term follow-up examinations (mean, 4.2 yr) revealed signs of definite tumor recurrence. The mean GH-plasma level at follow-up was 1.6 +/- 0.9 (mean +/- standard deviation) micrograms/L. One patient died 2 years after the operation of causes unrelated to pituitary surgery.(ABSTRACT TRUNCATED AT 250 WORDS)
