Radiotherapeutic Strategies and Advances in the Management of Pituitary Adenomas.

Abstract

Background: Pituitary adenomas are benign brain tumors that develop from hormone-producing cells in the anterior pituitary gland and account for 10-20% of all intracranial tumors. However, pituitary adenomas can have significant morbidity due to local invasion and changes to hormonal secretion. Though radiotherapy can result in side effects ranging from hypopituitarism to visual changes, radiation therapy remains an important tool due to its long-term benefits and high tumor control rates. Summary: Standard treatment for pituitary adenomas often includes surgical resection followed by radiation therapy. Recent developments in radiation delivery methods and techniques include external beam radiotherapy, stereotactic radiosurgery, proton therapy, and peptide receptor radionuclide therapy, which have improved precision while minimizing damage to healthy tissues. These advancements have continued to improve patient safety and long-term outcomes in cases of both functioning and nonfunctioning pituitary adenomas. Key Messages: Pituitary adenomas, while benign, can have significant clinical consequences. Advances in radiation therapy have expanded the therapeutic landscape to offer safer, more effective and more precise treatment options. Modern radiotherapy techniques have enhanced long-term outcomes and quality of life for patients with pituitary adenomas.
