Second-look surgery for intracranial germ cell tumors

Area of Science:

• Neuro-oncology
• Pediatric Oncology
• Surgical Oncology

Background:

• The clinical significance of second-look surgery for intracranial germ cell tumors (GCTs) requires further investigation.
• Optimal management strategies for GCTs with residual disease after chemotherapy are debated.

Purpose of the Study:

• To evaluate the efficacy and outcomes of second-look surgery in patients with intracranial GCTs.
• To assess the role of surgery in achieving complete tumor resection when markers normalize but residual disease is present.

Main Methods:

• Retrospective analysis of 7 patients with intracranial GCTs who underwent second-look surgery.
• Review of clinical data, imaging, tumor markers, and histopathology post-chemotherapy.

Main Results:

• Second-look surgery was performed on 7/23 (30%) patients after 1-3 chemotherapy courses.
• Gross total resection was achieved in all patients; histopathology revealed mature teratoma or fibrosis.
• All patients remain alive with no recurrence after a mean follow-up of 48 months.

Conclusions:

• Second-look surgery is a vital component in the management of intracranial GCTs.
• Early surgical intervention is recommended for residual GCTs, even with normalized tumor markers, to improve resection rates and patient outcomes.
