Abstract

Background. Acromegaly is a chronic disease impacting on morbidity and mortality. Increased mortality is reverted after the achievement of hormonal targets. The relative role of treatment options is still matter of debate. Methods. A retrospective chart review was performed on all the acromegalic patients attending our center along the last 20 years. Results. Data about 159 patients (83 F) were retrieved and analyzed: 18% had been lost to follow-up, while follow-up was >5 years in 79%. Growth hormone (GH) at diagnosis was 24 lg/L (median, range 3–239). Pituitary MRI showed a macro-, micro-adenoma or no lesion in 73.6, 22.9, and 3.5%, respectively. Hyperprolactinemia (hyperPRL) was present in 20.8%. Ninety-six and 29 patients had been treated by neurosurgery (NS) and irradiated (RT), respectively. Drugs had been employed in 149 patients (in 58 as the only treatment). At the last evaluation, 22% of patients were cured (hypopituitarism and GH deficiency in 6.3%), 37.1% were controlled by ongoing pharmacological treatment, 22.6% had discordant GH and Insulin-like growth factor I (IGF-I) values, and 18.2% had still active disease (median follow-up in this last group was 9 months). By evaluating the outcome with a multimodal approach, safe GH and normal IGF-I had been achieved in 78 and 63.5% of the whole series, 80.5 and 59.7% in patients submitted to NS (and adjuvantly treated with drugs), 95.8 and 91.7% in those submitted to NS + RT (and drugs as well), 70.2 and 55.2% in those treated only with drugs (increased to 82.2 and 60.9% if considering only patients treated with modern long-acting drugs).
