最近廿年来,肾母细胞瘤的预后已有明显的提高,这是由于儿科、外科、病理及放疗工作者共同协作努力的结果。本文资料采用美国国立Wilm瘤研究会建议之分期进行分类。Ⅰ期肿瘤仅为单侧肾区而无包膜破裂者,Ⅱ期:肿瘤单侧包膜已破裂但尚能全部切除者,Ⅲ期:肿瘤单侧延及腹腔但无血行播散,Ⅳ期:血行播散远处转移至肺肝骨脑等处。Ⅴ期:双侧肿瘤。对病理有重大影响者尚有其他因素:组织单分类,腹部淋巴结受累及或肿瘤结节数目,肿瘤大小与肿瘤之穿破等等。
In the recent 20 years, the prognosis of nephroblastoma has been significantly improved. This is due to the joint efforts of pediatrics, surgery, pathology, and radiotherapy workers. The data in this article were classified by stages recommended by the National Wilmian Cancer Research Society. Stage I tumors were unilateral renal areas without capsular rupture. Stage II: The unilateral capsule of the tumor had been ruptured but was fully resected. Stage III: Unilateral extension of the tumor and abdominal cavity but no hematopoietic dissemination, stage IV : Hematogenous spread distantly transferred to the lungs and liver bones and other places. Phase V: bilateral tumors. Those who have a major influence on pathology still have other factors: single tissue classification, abdominal lymph node involvement, or the number of tumor nodules, tumor size, and tumor puncture.
