Effects of Preoperative Serum Prolactin and Tumor Volume on Postoperative Remission in a Cohort of 219 Prolactinoma Resections

Objective: Prolactinomas can be managed medically with surgery reserved as second-line therapy. Postoperative remission can be difficult to predict, and prior studies have not examined how volume-adjusted prolactin relates to postoperative outcomes. We assessed the correlation between presurgical tumor volume and prolactin as well as its effect on surgical outcomes.
