Current Management of Intracranial Germ Cell Tumours.

Area of Science:

• Pediatric Oncology
• Neuro-Oncology
• Tumor Biology

Background:

• Intracranial germ cell tumors (icGCTs) are rare in pediatric and young adult populations.
• Classification typically divides icGCTs into germinomas and non-germinomatous germ cell tumors (NGGCTs).
• Germinomas demonstrate high curability with multimodal therapy, whereas NGGCTs present poorer prognoses.

Purpose of the Study:

• To review current global management strategies for icGCTs.
• To highlight research trends focused on optimizing treatment protocols.
• To investigate methods for reducing treatment-related late sequelae while preserving high cure rates.

Main Methods:

• Literature review of current research and clinical practice guidelines.
• Analysis of treatment modalities, including radiotherapy, chemotherapy, and surgery.
• Examination of outcomes data focusing on survival rates and long-term effects.

Main Results:

• Germinomas generally have favorable outcomes with established treatments.
• NGGCTs present significant therapeutic challenges and are associated with lower survival rates.
• Ongoing research prioritizes reducing radiotherapy dose and volume to mitigate long-term toxicity.

Conclusions:

• Tailoring treatment intensity is crucial for improving outcomes in icGCT patients.
• Minimizing late sequelae from radiotherapy is a key objective in current icGCT research.
• Further research is needed to refine treatment strategies for NGGCTs and reduce long-term adverse effects.
