| Outline of Final Research Achievements |
For the purpose of clarifying the factors related to the distant metastasis and poor prognosis in dedifferentiated liposarcoma, array CGH analysis and clinicopathological analysis were performed. We used a custom CGH array, which included dense coverage for genes in the areas known to be frequently amplified in dedifferentiated liposarcoma. As a result, High MDM2/HMGA2 ration in array CGH and histological grade, cellular atypia and MDM2 immunoreactivity in pathological analysis proved to be important prognostic factors.

| Academic Significance and Societal Importance of the Research Achievements |
本研究によって明らかになった予後予測因子は、個々の患者の予後予測に有用であるばかりでなく、MDM2/HMGA2比が予後と関連するという結果は、脱分化型脂肪肉腫の病態解明の一助となり、また免疫染色上MDM2の発現が高いほど予後不良であるという結果は、治療薬の開発にも糸口を提供するものである。
