【摘要】目的:对比分析青年与老年肾癌患者的病理特点的异同。方法和材料:将我院2005-2009年期间收治的84例符合条件的肾癌病例,按照年龄分为小于等于40岁的青年组(36例)和大于40岁的中老年组(48例),对其病理类型做对比分析。结果:两组病例病理类型均以透明细胞癌为主,所占比例分别是72.22%(26/36)和85.42%(41/48),在青年组发现5例Xp11.2易位/TFE3基因融合相关性肾癌,为老年组所没有的类型。结论:两组的病理类型均以透明细胞癌为主,但在青年组有Xp11.2易位/TFE3基因融合相关性肾癌,这一新的肾癌类型为今后青少年肾癌的研究提供了方向。

Pathologic Characteristics of Renal Cell Carcinoma in Young and Elder Patients WEI Ben-lin,GUAN Zhi-zhen
【Abstract】Objective:To compare and analyze the Pathological characteristics of renal cell carcinoma in young adults and elder patients.Methods:A retrospective review of 84 patients who were diagnosed with RCC from 2005 to 2009 was performed.They were divided into two groups:young(≤40 years,36cases)and elder(>40 years,48 cases).Their Pathological characteristics were analyzed.Results:Clear cell carcinoma was the main pathological type in both groups,and the rates were 72.22%(26/36,young adults)and 85.42%(41/48,elder).In the young patients groups there were five cases of renal cell carcinomas associated with Xp11.2 translocations/TFE3 gene fusions and there was no such cases in the elder group.Conclusions:The main pathological type in both groups was clear cell carcinoma. Renal cell carcinoma associated with Xp11.2 translocations /TFE3 gene fusions were specially found inyoung patients,and it's an important subject for study.

1.材料和方法
观察对象为本院自2005年至2009年经手术治疗确诊的84例肾癌患者。
诊断标准为经手术后病理切片诊断为肾细胞癌(Renal Cell Carcinoma,RCC),其病理分类按照2004年WHO分类标准。纳入标准为经手术治疗,临床资料齐全,随访依从性高者。排除标准为临床诊断肾癌但未经手术后病理确诊、资料不全、出院后无法随访者。观察指标为患者的病理类型。
1.1 一般资料:按以上标准,共纳入本组患者84例,按照年龄分成小于40岁青年组和大于40岁的中老年组两组。其中青年组有36例,中老年组有48例。青年组男性22例,女性14例,年龄18-40岁,平均31.4岁,住院天数10-34天,平均16.1天。中老年组男性36例,女性12例,年龄41-79岁,平均57.93岁,住院天数6-71天,平均17.2天。
1.2 临床表现:青年组偶发癌19例,有症状癌17例。其中腰痛者12例,血尿者9例,腰腹部包块者2例,部分患者同时有两种症状。右肾肿瘤17例,左肾肿瘤19例,其中下极肿瘤12例,中极肿瘤14例,上极肿瘤10例。TNM分期T1期24例,T2期3例,T3期4例(N1有2例),T4期5例,远处转移者(M1)1例。中老年组偶发癌30例,有症状癌18例,其中腰痛者8例,血尿者9例,腰腹部包块者1例,发热者1例。右肾肿瘤23例,左肾肿瘤25例,其中下极肿瘤18例,中极肿瘤21例,上极肿瘤9例 ......
