摘要
Objective: Analysis of patients with acromegaly followed-up at a single centre, focusing on baseline characteristics, morbidity and efficacy of treatment. Design and methods: Retrospective review of electronic medical records of acromegalics from 1987 to 2009. Results: One hundred and fifteen patients (45 men), aged 47 +/- 14 years, with a mean follow-up of 8.8 +/- 0.8 years were studied. Twenty-five per cent had micro-and 75% macroadenomas. Forty-three per cent presented with visual field defects, 49% had hypertension, 25% diabetes mellitus and 35% dyslipidaemia. At follow-up, 50% had myocardial hypertrophy, 55% colon polypodiasis, 74% nodular thyroid disease and 18% adrenal masses. Surgery was performed in 79% (8% twice), followed by conventional radiotherapy in 27%. Fifty-two per cent of the patients achieved remission. Disease control was reported in 65% of microadenomas and 41% of macroadenomas. Remission rates with surgery alone were 41%. Improvement of remission rates was achieved with subsequent treatment with somatostatin analogues (SSA) (53%), or conventional radiotherapy (63%). Nevertheless, pituitary reserve was compromised with the latter. SSA significantly improved outcomes in microadenomas, even as a monotherapy (remission in 89%), in contrast to macroadenomas (0%), although these agents were associated with impaired glucose metabolism and cholelithiasis in half of the patients. Conclusions: Acromegaly is associated with an increased morbidity. About half of the treated patients achieved remission (2/3 of microadenomas). The best outcomes were reported for the combination of surgery with radiotherapy, in spite of a higher risk of hypopituitarism. SSA led to remission in a significant percentage of microadenomas, but was associated with increased rates of cholelithiasis and impaired glucose homeostasis.
