Meta-analysis of cancer cell lines genomes based on their response to ttfields. They found a link between some genes and the tumor's response to TTF. This may open the door to find out why it works so well on some people and not at all on others. Perhaps this may lead to a screening test to determine if it is worth even trying or better yet to adding a drug that will allow TTF to work for everyone. Exciting concept.
Effect of tumor-treating fields on DNA repair in cancer cell lines. This shows that adding TTF to radiation may result in a big increase in the effectiveness of the radiation. However, this was only in the test tube and on renal cell cancer and not brain cancer so more work needs to be done before we can say it is good to use with brain tumor radiation.
