Radiotherapy for craniopharyngioma.

Area of Science:

• Radiation Oncology
• Neurosurgery
• Medical Physics

Background:

• Craniopharyngioma management often requires radiotherapy, especially for incompletely resected or recurrent tumors.
• Advances in imaging and radiotherapy technologies aim to enhance treatment accuracy and minimize radiation exposure to healthy brain tissue.

Purpose of the Study:

• To review current and emerging radiotherapy technologies for craniopharyngioma.
• To evaluate the technical advantages, disadvantages, and clinical outcomes of different radiotherapy approaches.
• To provide guidance on the optimal use of radiotherapy in craniopharyngioma management.

Main Methods:

• Review of published clinical results and technical data for various radiotherapy technologies.
• Analysis of image-guided fractionated conformal radiotherapy, single-fraction treatment, hypofractionation, and proton therapy.
• Assessment of the role of multidisciplinary teams and quality assurance in treatment delivery.

Main Results:

• Fractionated high-precision conformal radiotherapy with image guidance is the current gold standard.
• Single-fraction treatment yields disappointing results; hypofractionation requires caution due to limited long-term data.
• Insufficient data exists to assess the comparative efficacy and toxicity of proton therapy.

Conclusions:

• Precision radiotherapy delivery must be supported by experienced infrastructure and rigorous quality assurance.
• Management within multidisciplinary teams experienced in craniopharyngioma is essential.
• The benefits of multidisciplinary expertise may surpass the clinical gains from novel radiotherapy technologies alone.
