Significant tumour shrinkage after 12 months of lanreotide Autogel-120 mg treatment given first-line in acromegaly.

摘要

OBJECTIVE: To evaluate GH and IGF-I control and tumour shrinkage in newly diagnosed patients with acromegaly treated first-line with lanreotide-Autogel (ATG) 120 mg. Design Open, prospective. PATIENTS: Twenty-six patients (17 women, aged 31-70 years): eight enclosed and 12 extrasellar (eight invasive) macroadenomas and six microadenomas (one invasive). ATG 120 mg initially given every 4 weeks for 12 weeks; then intervals between injections increased to every 6 or 8 weeks if GH levels were 25% tumour shrinkage: 12 of 14 with controlled disease (85.7%) and 8 of 12 with noncontrolled disease (66.7%; P = 0.49). Hyperhydrosis, paresthesiae and arthralgias significantly reduced after treatment. No patient withdrew from the study because of adverse events. CONCLUSION: ATG 120 mg in newly diagnosed patients with acromegaly controls GH and IGF-I secretion in 53.8% and induces >or= 25% tumour shrinkage in 76.9% during a 12-month period. The treatment was associated with improvement of clinical symptoms and with a good safety profile.
