Outline of Final Research Achievements |
In neuroblastomas with elongated telomeres by ALT (alaternative lengthening of telomere) mechanism, telomere signals by FISH were heterogeneous. In these 24 tumors, 16 had ATRX mutations, 6 had ATRX deletions, and the remaining 2 had DRXX mutations. Clinically, the children with such tumors were advanced stage ones without MYCN amplification except for one case. These tumor showed chemotherapeutic resistant and poor outcome significantly. Such ALT activated neuroblastoma is rare but a discriminate tumor group with poor prognosis.
