| Research Abstract |
In this study, we tried to comprehend the immune accelerating or suppressive responses in patients' brain tumor tissues treated with WT1 peptide vaccination for malignant gliomas. And more, we considered whether the addition of WT1 peptide vaccination to temozolomide therapy, as an alternative treatment strategy for malignant gliomas, is feasible. The comparison between before and after WT1 peptide vaccination in brain tumor tissue showed the immune escape of tumor tissue. Temozolomide therapy did not significantly affect the frequency of WT1-specific CTLs, suggesting that the combination with WT1 peptide vaccination may be possible.
