Conventional external beam radiotherapy for central nervous system malignancies

Area of Science:

• Radiation Oncology
• Neuro-oncology
• Medical Physics

Background:

• Malignant central nervous system (CNS) diseases require multidisciplinary management.
• Neurologists and neurosurgeons often collaborate with radiation oncologists.
• Understanding radiotherapy's role is essential for non-radiotherapists.

Purpose of the Study:

• To review the role of conventional external beam radiotherapy in neuro-oncology.
• To provide a foundational understanding for clinicians not specializing in radiation therapy.
• To clarify the application of fractionated photon radiotherapy in CNS tumor treatment.

Main Methods:

• Literature review of established radiotherapy principles and practices in neuro-oncology.
• Synthesis of information on conventional external beam photon techniques.
• Focus on the clinical integration of radiotherapy for brain and spinal cord malignancies.

Main Results:

• Fractionated external beam photon radiotherapy is a standard treatment modality for CNS malignancies.
• Radiotherapy planning and delivery require specialized expertise.
• The article outlines the fundamental aspects of radiotherapy relevant to neuro-oncology.

Conclusions:

• Conventional external beam radiotherapy remains a vital component in the neuro-oncology armamentarium.
• Effective management of CNS tumors necessitates understanding the principles and applications of radiotherapy.
• This review serves as a guide for neurologists and neurosurgeons regarding radiotherapy's place in patient care.
