经腹肾癌根治术并系统性淋巴结清扫治疗肾细胞癌临床分析(附136例报告)

目的 评价经腹腔肾癌根治性肾切除术并系统性淋巴结清扫术的安全性和疗效.方法 回顾性分析2004年7月至2008年6月经腹直肌旁切口行根治性肾切除和系统性淋巴结清扫术治疗肾细胞癌136例患者的资料.男92例,女44例;年龄23～81岁,平均54岁.肿瘤最大径15～170 mm,平均55 mm.体检时B超检查发现66例(61%),以皮肤转移为首发症状者2例.术前均进行B超、CT及核素骨扫描检查,肿瘤临床分期:T1 108例,T2 14例,T3 12例,T4 2例.结果 本组手术时间90～180 min,平均120 min.出血量20～400 ml,平均50 ml.术后肠道功能恢复时间为(24±12)h,术后住院天数为(7±2)d.术后病理结果:肾透明细胞癌123例(90.4%),乳头状肾细胞癌6例(4.4%),嫌色细胞癌2例(1.4%),集合管癌2例(1.4%),其他3例(2.2%).淋巴结转移8例.T1期92例,T2期11例,T3期10例,T4期10例.95例(69.9%)获随访,随访时间6～40个月,平均20个月.1、3年生存率分别为95.8%(91/95)、86.3%(82/95).结论 系统性淋巴清扫肾癌根治术能有效切除肿瘤,可准确分期,防止局部复发,安全可靠,疗效良好.

Abstract：

Objective To assess the safety and efficacy of abdominal radical nephrectomy and systematic lymph node dissection for treatment of renal carcinoma. Methods A total of 136 patients underwent radical nephrectomy and regional clearance of lymph nodes from July 2004 to June 2008.There were 92 males and 44 females in the study group.Ages ranged from 23 to 81 years,with a mean age of 54 years.The mean tumor diameter was 55 mm (range,15-170 mm).The tumor size detected by CT and MRI was consistent with that detected by B-ultrasound,98 were stage Ⅰ,13stage Ⅱ,12 stage Ⅲ,and 2 stage Ⅳ. Results All 136 cases underwent radical nephrectomy with retroperitoneal lymphadenectomy.All operations were successful without any major complication.The operative time was 90 to 180 min,with an average of 120 min,and blood loss was 20-400 ml,with an average of 50 ml.The pathological diagnoses were as follows: renal cell carcinoma 123 cases (90%), papillary renal cell carcinoma six cases(4%),chromophobic two cases(1.4%),oncocytoma two cases(1.4%),collecting duct two(1.4%),and others three cases(2.2%).Eight cases reported positive lymph nodes.Of the 136 cases,92 cases were T1 N0 M0,11 were T2 N0 M0,10 were T3 N0 M0,eight were T3 N1 M0 and two were T1 N0 M1.Ninety-five cases (70%) were followed-up at six to 40 months (mean,20 months).The one year and three year survival rates were 96% (91/95) and 86% (82/95),respectively.Conclusions Radical nephrectomy with systematic lymph dissection has advantages of accurate staging,effective resecting of renal tumors and preventing recurrence.Radical nephrectomy is an effective method for the treatment of renal carcinoma.
