Updating the Landscape for Functioning Gonadotroph Tumors

Area of Science:

• Endocrinology
• Oncology
• Neurosurgery

Background:

• Functioning gonadotroph adenomas (FGAs) are rare pituitary tumors, unlike most clinically silent gonadotroph tumors.
• These tumors are often poorly differentiated, leading to inefficient hormone production.

Purpose of the Study:

• To review recent literature on functioning gonadotroph adenomas.
• To highlight the diagnostic and therapeutic management of these rare tumors.

Main Methods:

• Literature review of case reports and small case series.
• Analysis of clinical presentation, hormonal hypersecretion, and treatment outcomes.

Main Results:

• FGAs can cause clinical syndromes like ovarian hyperstimulation syndrome, testicular enlargement, and precocious puberty due to gonadotropin hypersecretion.
• Transsphenoidal surgery effectively reduces hormonal hypersecretion and improves endocrine dysfunction.
• Medical therapies, including somatostatin analogues and dopamine agonists, often have limited efficacy for both hormonal control and antitumor effects.

Conclusions:

• Functioning gonadotroph adenomas require specific management strategies due to their rarity and potential for significant endocrine disruption.
• Surgical resection remains the cornerstone of treatment, with medical therapies playing a supportive or alternative role in select cases.
