Recent advances in understanding and managing pituitary adenomas

Area of Science:

• Neuro-oncology
• Endocrinology
• Surgical Neurology

Background:

• Pituitary adenomas (PAs) are common intracranial tumors with potential for hormonal disturbances, local compression, and rare aggressive behavior or metastasis.
• Early diagnosis and treatment of PAs are crucial due to their potential morbidity.
• Understanding PA pathogenesis is advancing through molecular pathology, offering new therapeutic targets.

Purpose of the Study:

• To review current understanding and management strategies for pituitary adenomas.
• To highlight advances in diagnosis, surgical techniques, medical therapies, and radiotherapy for PAs.
• To emphasize the evolving landscape of personalized treatment approaches for PAs.

Main Methods:

• Review of current literature on pituitary adenoma diagnosis and treatment.
• Discussion of advances in molecular pathology, imaging, and functional molecular techniques.
• Overview of established and emerging therapeutic modalities including surgery, pharmacotherapy, chemotherapy, and radiotherapy.

Main Results:

• Transsphenoidal surgery, particularly endoscopic neurosurgery, is the first-line treatment for most PAs.
• Pharmacological treatments include dopamine agonists for prolactinomas, somatostatin analogues for acromegaly, and various agents for Cushing's disease.
• Chemotherapy (Temozolomide) and novel experimental therapies are available for aggressive PAs, alongside radiotherapy for residual or progressive tumors.

Conclusions:

• Significant progress has been made in understanding and treating pituitary adenomas.
• A multidisciplinary approach combining surgery, medication, and radiotherapy offers improved outcomes.
• Future directions focus on tailoring and personalizing treatment based on individual PA biology and patient characteristics.
