| Research Abstract |
We have prospectively conducted, on a daily basis, molecular studies on all resected gliomas including CGH and methylation-specific PCR of the MGMT gene. As a result, we found that adult supratentorial grade 2-3 gliomas are divided into clinically relevant subgroups by genetic profile (Hirose, 2011), and that single-copy gain of chromosome 1q is frequent in pediatric gliomas, and is associated with poor clinical outcome (Miwa, 2011). Moreover, we have treated 21 1p/19q-codeleted gliomas by neoadjuvant approach, and, of them, second-look removal after chemotherapeutic response was performed in 8 cases. There has been no recurrence in those tumors, and our results suggest efficacy of neoadjuvant approach for chemosensitive gliomas.
