要約 目的:網膜芽細胞腫に対する治療成績の報告と国際分類(2003)の評価。対象と方法:2008年までの7年間に網膜芽細胞腫21例29眼が受診した。初診時の年齢は1~106か月(平均18か月)で,男児13例(62%),女児8例(38%)であり,13例が片眼,8例が両眼発症であった。初回治療として眼球を摘出しなかった24眼に,化学療法と経瞳孔温熱療法による保存治療を行った。国際分類による24眼の内訳は,A群0眼,B群11眼,C群1眼,D群9眼,E群3眼であった。結果:24眼のうち眼球が温存できたのは,B群11眼(100%),C群1眼(100%),D群2眼(22%),E群0眼であった。結論:網膜芽細胞腫に対する化学療法を主とする治療成績は,国際分類をよく反映している。
Abstract. Purpose:To report the outcome of conservative treatment for retinoblastoma and to evaluate the International Classification of Retinoblastoma(2003). Cases and Method:A total of 29 eyes of 21 patients were diagnosed with retinoblastoma during 7 years through 2008. The series comprised 13 male and 8 female infants. Thirteen cases were unilaterally and 8 cases were bilaterally involved. The age at the initial visit ranged from 1 to 106 months,average 18 months. Enucleation had to be performed on 5 eyes as initial treatment. The other 24 eyes received chemotherapy and transpupillary thermotherapy. The 24 eyes comprised stage B 11 eyes,stage C 1 eye,stage D 9 eyes,and stage E 3 eyes. Results:The eyeglobe could be preserved in 11 eyes of stage B(100%),1 eye of stage C(100%),2 eyes of stage D(22%),and none of stage E. Conclusion:The outcome of treatment in the present cases is well in accord with the International Classification of Retinoblastoma.
