Outline of Final Research Achievements

Giant cell tumor of bone is an intermediate tumor that may show local recurrence and/or metastasis. We performed a clinicopathological analysis of 213 cases, having primary surgery, and statistically elucidated the predicting factors for recurrence (62 cases) and 2nd relapse (14 cases). As a result, Cox's hazard univariate analysis revealed that six characteristics, such as, younger age, curettage, frequent mitosis, less interstitial hemorrhage, no ischemic necrosis, and more vascular invasion, were significant predicting factors for the first recurrence. In multivariate analysis, the five features other than curettage were significant. We tried to elucidate the risk factors for 2nd relapse in 1st recurrent patients treated with surgery, but no significant factors were found within above mentioned five features, being significant in analysis of the first recurrence. The only significant risk factor for 2nd relapse was the administration of denosumab, a therapeutic drug for this tumor.

Academic Significance and Societal Importance of the Research Achievements

骨巨細胞腫の再発・転移を予想因子が分れば、治療戦略に大きな変化をもたらす。本研究は、初回手術例では、年齢やいくつかの組織所見が局所再発の予見に役立つことが示された。組織学的所見は日ごろの病理診断の際に容易に評価することが可能なものばかりで、診療への応用がすぐにでも可能である。一方、初回再発に有意に関与した因子は、再発術後再々発に有意に関与しなかった。初回再発後の治療法には掻爬や切除の手術と、さらにdenosumabなどの薬剤を単独あるいは手術と組み合わせた治療などがあるが、手術例に限ると同薬剤の投与は再々発の有意なリスク因子となった。同薬剤の投与法については今後検討を要する。
