1982～1992年间,我院收治 97例肾细胞癌(RCC)患者,基中15例发生远隔转移和16例未发生远隔转移的T_3～T_4期病人接受了保守性手术,其余66例T_1～T_3期的病人接受了根治性肾切除和淋巴结清扫术。经过平均6.7年的随访,分析发现:在行根治性肾切除和淋巴结清扫病人中,分期对术后5年生存率具有显著影响(P<0.005);T_3期病人是否施行淋巴清扫则对此无意义(P>0.05)。淋巴结清扫的意义还在于使术后孤立性转移灶的清除变为可能,为术后联合性的生物免疫及化学治疗和肿瘤性并发症的处理提供了良好的临床基础。
Between 1982 and 1992, 97 patients with RCC were treated in our hospital. Twenty-three T_3-T_4 patients with distant metastasis and 16 patients without distant metastasis were treated conservatively in the study. The remaining 66 T_1 ~ T_3 patients underwent radical nephrectomy and lymph node dissection. After an average of 6.7 years of follow-up, the analysis found that: in patients who underwent radical nephrectomy and lymph node dissection, the staging had a significant effect on the 5-year survival rate (P <0.005); T_3 patients performed lymphadenectomy without this Significance (P> 0.05). The significance of lymph node dissection is to make the removal of isolated solitary metastases possible, postoperative combined with biological immunity and chemotherapy and neoplastic complications provide a good clinical basis.
