Objective: Transsphenoidal (TNS) surgery remains the primary therapeutic option for GHsecreting pituitary adenomas. The aims of this study were to verify the impact of TNS surgery on treatment of acromegaly before and after identification by a dedicated neurosurgical team and to enumerate diagnostic features of the disease described over three decades. Design: 41 patients (group A) who underwent TNS surgery by a dedicated neurosurgical team (2000- 2008) and 126 patients (group B) operated on by surgeons not specialized in pituitary surgery (1979-1999) were retrospectively analyzed. RESULTS: No significant differences were observed between the two groups in terms of delay of diagnosis, mean basal GH levels and GH nadir values, prevalence of hypopituitarism and hypertension. IGF-I SDS were significantly higher, while prevalence of IGT/diabetes was significantly lower in group B than in group A. Overall remission rate after surgery was 58.5% for group A (75% in microadenomas and 48% in macroadenomas, P=NS) and 37% for group B (P<0.05 vs group A; for microadenomas, 34% vs 75% of group A, P<0.05, for macroadenomas, 36% vs 48% of group A, P=NS). The mean delay of diagnosis was 4.9 and 5.9 years in group A and B, respectively. Conclusions: Our data confirm that a dedicated neurosurgical team is needed in order to improve remission rates in acromegalic patients. No changes in biochemical, clinical and neuroradiological presentation of disease were observed over the last three decades. As the high prevalence of macroadenomas negatively influences surgical cure, earlier diagnosis should be considered as mandatory to achieve a better outcome.
