Outline of Final Research Achievements

Pediatric malignant soft tissue tumor has a poor prognosis, and a new therapeutic target is desired. Currently, Forkhead box M1 (FOXM1) is one of the most notable molecules as a new therapeutic target in major malignant tumors.
We evaluated FOXM1 expression in 92 patients with rhabdomyosarcoma (RMS) and 106 synovial sarcoma (SS) among pediatric malignant soft tissue tumors. We showed that FOXM1 expression is associated with poor prognosis. In RMS, FOXM1 correlated with VEGF expression and angiogenesis. In cDNA microarray analysis of SS cases, we showed that cell cycle related gene expression correlates with FOXM1 expression. We showed that FOM1 inhibition could be a new treatment option in studies of cell lines of each tumor.
