Prolactin‐Secreting pituitary tumors

Abstract

Abstract Prolactin secretion was evaluated in 69 patients with pituitary tumors. Among the 47 who were seen prior to treatment, hyperprolactinemia was present in 37 (79%). Excluding patients with galactorrhea, hyperprolactinemia was present in 19 (70%) of those seen before treatment. There was little correlation between tumor size and level of serum prolactin. Both transspheoidal surgery and radiotherapy greatly reduced the hyperprolactinemia, but a more rapid decrease was achieved with microsurgical removal of the secreting adenoma.
