Hypothesis

Can combining Tumor Treating Fields (TTFields) with chemotherapy enhance treatment efficacy without increasing toxicity?

Conclusion

Combining chemotherapeutic cancer treatment with TTFields may increase efficacy and sensitivity without increasing treatment-related toxicity.

Supporting Evidence

  • TTFields increased sensitivity to chemotherapy by 1–3 orders of magnitude.
  • Patients treated with TTFields and Temozolomide had a median progression-free survival of 155 weeks.
  • Overall survival for patients receiving combined treatment was over 39 months.

Takeaway

Using special electric fields along with cancer drugs can make the drugs work better without making people feel worse.

Methodology

The study involved in-vitro experiments on cancer cell lines, in-vivo experiments on animal models, and a pilot clinical trial with GBM patients.

Potential Biases

Potential bias due to the involvement of employees from the company developing TTFields.

Limitations

The study was limited to a small sample size and specific cancer types.

Participant Demographics

20 patients with histologically proven glioblastoma multiforme (GBM), including recurrent and newly diagnosed cases.
