We investigated the effectiveness of lanreotide for the treatment of active acromegaly in a retrospectively multicenter case series including 53 patients (24 male, 29 female; mean age at diagnosis, 49.5 ± 13.9 years) with acromegaly treated with lanreotide in nine different centers. Mean tumor diameter was 20 ± 13 mm; mean basal levels of growth hormone (GH) and insulin-like growth factor I (IGF-I) were 21.3 ± 26.3 and 579 ± 177 μg/l, respectively. The primary mode of treatment was surgery in 70% of patients. Twenty-nine patients received only lanreotide (Prolonged Release, Autogel), whereas 24 subjects were also treated with octreotide at another treatment stage. Primary therapy with lanreotide was administered in five patients. Maximal monthly dose of lanreotide Autogel (n = 44) was 60 mg in 45%, 90 mg in 26%, 120 mg in 21% and 180 mg in 8%. During 36 months of lanreotide treatment, mean IGF-I levels decreased from 443 ± 238 to 276 ± 147 μg/l (< 0.001), and mean GH levels, from 5.2 ± 6.4 to 3.2 ± 3.0 μg/l (P < 0.001). IGF-I levels normalized in 51% of patients and decreased by >50% towards normal in 32%; the normalization rate was higher in women (65%) than men (33%, P = 0.04). Safe random GH levels (≤2 μg/l) were achieved in 49% of patients. Both IGF-I normalization and safe GH levels were reached in 32% of the cohort. Lanreotide is an effective treatment for active acromegaly. Female sex was associated with higher rates of IGF-I normalization.
