Tumor-treating fields (TTFields) significantly improve survival outcomes for glioblastoma patients when combined with radio chemotherapy. This novel treatment also shows a favorable safety profile with fewer adverse events compared to conventional chemotherapy.
Area of Science:
- Neuro-oncology
- Medical Physics
- Clinical Trials
Background:
- Glioblastoma is an aggressive brain tumor with limited treatment options.
- Conventional radio chemotherapy offers modest survival benefits.
- Novel therapeutic approaches are needed to improve patient outcomes.
Purpose of the Study:
- To systematically review and compare the efficacy and safety of tumor-treating fields (TTFields) plus radio chemotherapy versus conventional radio chemotherapy alone in glioblastoma patients.
- To synthesize evidence from existing literature to inform clinical practice and future research.
Main Methods:
- Systematic literature search conducted in PubMed, Cochrane Library, and Scopus databases.
- Adherence to PRISMA guidelines for study selection and data extraction.
- Inclusion of six studies with 1806 patients for qualitative and 1769 for quantitative analysis.
Main Results:
- TTFields demonstrated significant improvements in median overall survival (WMD 3.29 years) and progression-free survival (WMD 2.35 months).
- Survival rates at 1 and 2 years were significantly higher in the TTFields group (OR 1.81 and 2.33, respectively).
- TTFields were associated with fewer adverse events compared to chemotherapy, with similar skin irritation rates.
Conclusions:
- Tumor-treating fields (TTFields) represent a safe and effective novel treatment modality for glioblastoma.
- Further randomized controlled studies with longer follow-up are warranted to fully elucidate the clinical benefits of TTFields.

Electric Field
In the new picture, imagine that the first charge sets up an electric field independent of all other charges in the universe. When another charge comes in its vicinity, the second charge experiences an electric force depending on the electric field at that point. The source charge does not...
