[Second-look operation for childhood solid malignancy].

Forty-four cases with childhood solid malignancy during the period from 1973 to 1982, were analysed. 11 cases underwent second-look operation, including 4 neuroblastomas, 4 hepatoblastomas, 1 malignant teratoma, 1 nephroblastoma, and 1 rhabdomyosarcoma. Two cases of hepatoblastoma in second-look operation are surviving over two years with no evidence of disease, and one case survived 5 years 8 months. For one patient of initially unresectable neuroblastoma, second-look operation was successfully performed by complete resection followed by paraortic-lymphonode dissection. In two cases of Wilms' tumor and malignant teratoma, second-look operations were performed for the purpose of treatment decision after radical operation. In the unresectable tumors or recurrent tumors or metastatic lesions, complete cure can be expected by aggressive surgical approach and combination chemotherapy followed by second-or third-look operation.
