| Outline of Final Research Achievements |
Genomic aberration was analyzed in 27 childhood cancer survivors who underwent treatments in Hiroshima University Hospital after 1980 and could have their own children. Among them, 15 cases had genomic aberrations which were significantly correlated to whole body irradiation and high-dose chemotherapy in their history. The analysis of these aberrations in their children suggested the possibility that hereditary transmission occurred in 3 cases but the common characteristics were not identified in these 3 cases. And in 5 of 6 cases who had secondary malignancies had genomic aberrations.
These results revealed that genomic aberration due to cancer treatments were identified in the childhood cancer survivors and some of them were transmitted in their children.
