Brain metastasis is a very common disease with poor prognosis, 20% cancer will develop brain metastases(BM), up to 40% by autopsy. Great advances have made with the application of targeting therapy, immunotherapy, chemotherapy, whole brain radiation and radiosurgery, however, treated patients were finally suffered from drug/radiation resistance and rapid recurrence. Tumor treating fields (TTFields) is one of the standard combination treatment for GBM, and some researchers believe that TTFields can effectively inhibit patient-derived lung adenocarcinoma brain metastasis cells progression in vitro. In this study, the investigator attempts to evaluate the safety, and tolerability of TTFields in adult participants diagnosed with Drug/Radiation resistant BM.
