Efficacy and safety of dopamine agonists in patients treated with antipsychotics and presenting a macroprolactinoma.

Context: In patients treated with antipsychotics, the rare occurrence of a macroprolactinoma represents a therapeutic challenge.

Objective: Our aim was to evaluate the efficacy and psychiatric safety of dopamine agonists (DAs) prescribed for large macroprolactinomas in patients with psychosis treated with antipsychotics.

Design: This was a multicenter (France and Belgium) retrospective study.

MRI T2 signal intensity and tumor response in patients with GH-secreting pituitary macroadenoma: PRIMARYS post-hoc analysis.

Objective Pituitary adenoma MRI T2 signal intensity associates with tumor characteristics including responsiveness to somatostatin analogs (SSAs). These analyses determined whether baseline T2 signal intensity predicts response to primary medical treatment with long-acting SSA. Design Post-hoc analyses of the prospective multicenter, open-label, single-arm PRIMARYS study in which patients with treatment-naïve GH-secreting pituitary macroadenomas received fixed-dose lanreotide autogel (120mg) every 4-weeks for 48-weeks.
