14年内作者对36名肾细胞癌患者进行保守性手术治疗。据治疗指征及对侧肾脏情况将病人分成三组;组1为孤立肾或双侧肾肿瘤;组2有对侧肾功能损害;组3为无对侧肾功能异常的病人。组1(绝对保守性手术)16人,行肿癌剜除术7例,肾极切除术9例;组2(扩大绝对保守性手术)10人,行肿瘤剜除术6例,肾极切除术4例;组3(选择性保守手术)10人,行肿瘤剜除术7例,肾极切除术3例。术后平均随访46.6月。两年生存率与六年生存率:组1分别为92％和58％;组2均为100％;组3分别为100％和66％。疗效与根治性手术相比无显著性差异。
Within 14 years, the author performed conservative surgery on 36 patients with renal cell carcinoma. According to indications for treatment and contralateral renal conditions, the patients were divided into three groups; Group 1 was a solitary or bilateral renal tumor; Group 2 had a contralateral renal impairment; Group 3 was a patient with no contralateral renal dysfunction. Group 1 (absolutely conservative surgery) 16 patients who underwent neoplasms enucleation surgery in 7 cases and nephrectomy in 9 cases; group 2 (enlargement of absolute conservative surgery) in 10 patients, 6 patients underwent tumor enucleation surgery, and resection of the kidney Four patients underwent surgery; 10 patients underwent selective conservative surgery; 7 patients underwent tumor enucleation and 3 patients underwent resection. The average follow-up time was 46.6 months. Two-year survival rate and six-year survival rate: Group 1 was 92% and 58% respectively; Group 2 was 100%; Group 3 was 100% and 66% respectively. There was no significant difference in curative effect compared with curative surgery.
