Summary
Premenopausal women with nonfunctioning pituitary macroadenomas (NFPMA) experience better hormonal outcomes after surgery. These findings suggest premenopausal women benefit most from pituitary surgery for NFPMA.
Area of Science:
- Endocrinology
- Neurosurgery
- Oncology
Background:
- Nonfunctioning pituitary macroadenomas (NFPMA) can cause hormonal deficiencies.
- Limited data exists on gender-specific hormonal outcomes after NFPMA surgery.
Purpose of the Study:
- To investigate gender differences in hormonal outcomes following pituitary surgery for NFPMA.
- To assess the impact of NFPMA on hormonal function in men and women.
Main Methods:
- Retrospective review of 122 patients undergoing initial surgery for NFPMA.
- Hormonal function assessed preoperatively and 6 months postoperatively.
- Tumor size and invasion evaluated via MRI.
Main Results:
- Men had higher rates of preoperative multiple hormone deficiency (47% vs 28%).
- Postoperatively, premenopausal women showed significantly better outcomes (14% deficiency) compared to postmenopausal women (36%) and men (46%).
- Premenopausal women exhibited superior gonadal axis recovery (60% vs 19% in others).
Conclusions:
- Premenopausal women with NFPMA demonstrate favorable hormonal outcomes post-surgery.
- Smaller tumor size and potentially shorter disease duration may contribute to better outcomes in premenopausal women.
- Pituitary surgery is recommended for premenopausal women with NFPMA due to significant potential for hormonal function restoration.
