GEN-13 FIREWORK PATTERN OF CANCER GENESIS FOR GLIOBLASTOMA, IDH-WILDTYPE

Treatment of Glioblastoma (GBM), IDH-wildtype is a history of sequential failure. The cure for this disease is a distant story, and it is really the emperor of cancer. We believe that GBM should not be considered one of several cancers, and GBM is a cancer that occurs in a special environment called the central nervous system (CNS). What is the biggest difference between other cancers and cancers of the nervous system? It is thought to be neurogenesis. This presentation will review GBM genesis based on neurogensis of CNS. It also explains what the cell of origin is, what somatic mutations occur at the cell of origin, and why these somatic mutations occur. Human glioblastoma (GBM) occurs in a place without cancer tissue, that is, in the subventricular zone and have introduced the name of the firework pattern of cancer genesis, which is a metaphorical representation of the GBM genesis. So far, we have been trying to develop therapeutics focused on bulk tumors. However, in the case of GBM, IDH-wildtype, it has been found that the cell of origin is not in the tumor but is in normal SVZ, so it is now considered that the therapeutic target should also include the cell of origin.
