Summary
Neoadjuvant therapy can shrink advanced frontal skull base tumors, enabling less invasive "targeted surgery." This approach aims to improve patient quality of life by reducing treatment-related disability.
Area of Science:
- Oncology
- Neurosurgery
- Skull Base Surgery
Background:
- Locally advanced frontal skull base tumors (T4 stage) have a poor prognosis, necessitating multimodal treatment strategies.
- Minimizing treatment-related disability is crucial for preserving patients' quality of life.
- Evidence-based therapeutic strategies for these rare tumors are lacking.
Observation:
- Three patients with extended frontal skull base malignomas (T4) were evaluated.
- A multimodal therapy concept included high-dose neoadjuvant therapy for tumor downsizing.
- Tumor remission created space for non-traumatic surgical manipulation.
Findings:
- Neoadjuvant therapy facilitated tumor downsizing, allowing for safer resection.
- Minimally invasive resection was achieved using navigated endoscopic or microscopic techniques.
- This
- targeted surgery
- approach reduced trauma during tumor removal.
Implications:
- Controlled tumor downsizing enables minimally invasive resection of T4 frontal skull base tumors.
- Instrumental navigation and reduced-trauma approaches can improve surgical outcomes.
- This strategy may enhance the feasibility of radical tumor resection while preserving neurological function and quality of life.
