Aim. This study aimed to investigate the clinical presentation and treatment outcomes of newly diagnosed acromegaly patients treated with various combinations\r\nof treatment modalities.\r\nMaterials and Methods. Eighty-four acromegaly patients (42 female, 42 male, mean age 40.29?13.32 y), followed and\r\ntreated between 2000 and 2010 were included. Data on patient demographics, delay between onset of symptoms and the\r\ndiagnosis, details of treatments, and treatment- or disease-related morbidity and mortality were collected and analyzed. The median delay time for diagnosis was 60.71 ? 56.19 months. Patients received various combinations of surgery, gamma knife radiotherapy or conventional radiotherapy,\r\nlong acting somatostatin analogue, and dopamine agonist.\r\nResults. After ten years of treatment, median GH and IGF-1 values decreased from 13.7 ng/mL (IQR: 5.3- 34) to 1.04\r\nng/mL (IQR: 0.52-2.7) and from 600 &#956;g/L (IQR: 460.5-787.5) to 194 &#956;g/L (IQR :157-356), respectively (p<0.0001).\r\nMedian GH during 75 g oral glucose tolerance test (OGTT) decreased from 4.35 ng/mL (IQR: 1.87-13.15) to 1.40 ng/mL\r\n(IQR: 0.60-3.40) (p<0.0001). Fifty patients (59.5%) were in remission according to IGF-1 values and 52 patients (62 %) were cured according to nadir GH during OGTT respectively. The mortality rate was 5.9%.\r\nIn conclusion. Strict biochemical control following appropriate intervention significantly reduces both morbidity and mortality in acromegaly patients.
