Abstract Background Evidence from controlled trials has shown that lanreotide autogel is effective in achieving biochemical and symptom control in patients with acromegaly. However, it is important to better understand the real-world patient population receiving lanreotide autogel treatment. Methods In this non-interventional study the long-term treatment response to lanreotide autogel in adult patients with acromegaly from office-based centers or clinics in Germany, Austria and Switzerland was studied. Assessments included growth hormone and insulin-like growth factor-I levels, symptoms, quality of life, lanreotide plasma levels and tumor somatostatin receptor subtype expression. The primary endpoint was achievement of full biochemical control, defined as growth hormone ≤2.5 µg/L and insulin-like growth factor I normalization at month 12. Results 76 patients were enrolled from 21 sites. 7/51 (13.7%) patients of the efficacy population had full biochemical control at baseline, 15/33 (45.5%) at month 12 and 10/26 (38.5%) at month 24 of treatment. At 12 months of treatment higher rates of biochemical control were observed in the following subgroups: older patients (>53 years [median]), females, treatment-naïve patients, and patients with a time since diagnosis of longer than 1.4 years (median). No clinically relevant differences in acromegaly symptoms or quality of life scores were observed. Median fasting blood glucose and glycated hemoglobin levels remained unchanged throughout the study. No new safety signals were observed. Overall tolerability of treatment with lanreotide autogel was judged by 80.8% of the enrolled patients at month 12 as ‘very good’ or ‘good’. Conclusion Treatment with lanreotide autogel in a real-world setting showed long-term effectiveness and good tolerability in patients with acromegaly.

Abstract BACKGROUND: Acromegaly is a disorder characterized by hypersecretion of growth hormone caused by a growth hormone–secreting pituitary adenoma. OBJECTIVE: To evaluate the long-term efficacy and safety of repeat transsphenoidal surgery for persistent or recurrent acromegaly. METHODS: We retrospectively reviewed records for 53 acromegalic patients who underwent repeat transsphenoidal surgery for persistent or progressive acromegaly at Toranomon Hospital between 1987 and 2006. Multivariate logistic regression was performed to evaluate preoperative factors influencing the surgical outcome. RESULTS: Thirty-one patients (58.5%) met the criteria for cure on long-term follow-up endocrine findings. Furthermore, 17 patients were well controlled with normal insulin-like growth factor I levels without (2 patients) or with medication (15 patients), whereas insulin-like growth factor I levels were still above normal in 5 patients after postoperative adjuvant therapy. Only 1 patient was undergoing additional hormonal replacement after surgery, although transient cerebrospinal fluid leak, transient abducens nerve palsy, severe nasal bleeding, and pituitary abscess occurred in each patient, respectively. Multivariate analysis clarified that a favorable surgical outcome was achieved in patients without cavernous sinus invasion (hazard ratio 12.56), tumor segmentation (hazard ratio 5.82), or in those older than 40 years old (hazard ratio 3.21). CONCLUSION: Repeat surgery can be performed safely with an approximately 60% long-term cure rate in this series. Reoperation should therefore be considered for persistent or recurrent disease in acromegalic patients in whom adjuvant therapy is not effective enough or cannot be accepted. The careful study of initial or preoperative magnetic resonance imaging and the use of micro-Doppler, endoscope, and eye movement monitoring device during surgery can help increase cure rate with a lower complication rate.
