Whole Ventricle Radiation (Germinoma)

Summary

This course provides a comprehensive overview of pure germinoma, a type of intracranial germ cell tumor. It covers diagnosis, classification, and modern treatment strategies focusing on whole ventricular radiation therapy. Participants will learn the rationale behind radiation fields and practical contouring techniques.

Key Learning Objectives

• Recognize and classify intracranial germ cell tumors, specifically pure germinomas.
• Understand current treatment paradigms including chemotherapy and radiation therapy for localized disease.
• Explain the rationale for whole ventricular irradiation (WVI) based on CSF flow patterns.
• Apply established contouring atlases (ACNS1123, ACNS2021) for WVI planning.
• Delineate gross tumor volumes and clinical target volumes, including ventricles and other critical structures.

Why You Should Attend

• Gain up-to-date knowledge on diagnosing and managing rare CNS germ cell tumors.
• Learn about de-escalated and dose-adapted radiation therapy for improved patient outcomes.
• Enhance your skills in precise radiation contouring for whole ventricular irradiation.
• Understand the controversies and latest recommendations in treatment field definitions.
• Optimize treatment plans by incorporating current guidelines and best practices.

Topics Discussed

• Intracranial germ cell tumor (IGCT) epidemiology and types.
• Diagnosis and classification of pure germinomas.
• Role of tumor markers (AFP, beta-HCG) in diagnosis.
• Modern treatment strategies: chemotherapy and radiation.
• Rationale for Whole Ventricular Irradiation (WVI).
• Cerebrospinal fluid (CSF) flow and its relevance to WVI.
• Contouring techniques for whole ventricular volume.
• Comparison of ACNS1123 and ACNS2021 atlases.
• Inclusion of pre-pontine cistern and biopsy tracts.
