Radiosurgery offers a precise and effective treatment for pituitary adenomas, reducing risks and speeding recovery compared to traditional radiation therapy for residual or recurrent tumors after surgery.

Area of Science:

  • Neurosurgery
  • Radiation Oncology
  • Endocrinology

Context:

  • Pituitary adenomas are common intracranial tumors, often requiring multimodal treatment.
  • Microsurgery is standard, but 30% need further treatment for residual or recurrent tumors.
  • Fractionated radiotherapy is traditional, but radiosurgery is an emerging option.

Purpose:

  • To review the efficacy, safety, and role of radiosurgery in treating pituitary adenomas.
  • To compare radiosurgery with fractionated radiotherapy.
  • To present institutional preliminary results.

Summary:

  • Radiosurgery delivers precise radiation to pituitary adenomas, sparing surrounding tissues.
  • This precision lowers risks of hypopituitarism, visual damage, and vasculopathy.

  • Radiosurgery shows a shorter latency for radiation response than fractionated radiotherapy.

    • Impact:

    • Radiosurgery provides a safer and potentially faster treatment alternative for pituitary adenomas.
    • Improved precision in tumor targeting enhances patient outcomes.
    • This review informs clinical decision-making for pituitary adenoma management.
