【摘要】:目的:长期以来,施行肾癌根治术时,是否同时行淋巴结清扫术以及淋巴结清扫的范围一直存在争议。在过去的10年,泌尿外科医生行淋巴结清扫术的数量呈持续下降趋势,主要是由于现在没有研究结果能证明淋巴结清扫术肯定能带来益处,在这个回顾性研究中,我们收集分析了2003年至2010年大连医科大学附属第一医院诊断肾癌行肾癌根治术并施行(或未施行)淋巴结清扫术的患者资料,对比患者的术后复发转移情况及生存时间,以期对肾癌根治术中淋巴结清扫的意义进行探讨。 方法:我们通过电子病历系统查阅了2003年至2010年大连医科大学附属第一医院行肾癌根治术患者的资料共1158例。随访对象的入选条件为:病理诊断为肾细胞癌并行肾癌根治术;剔除条件为:治疗同时或之前发生其他恶性肿瘤,手术治疗时已经有远处转移,术后使用靶向药物。根据2010年AJCC发布的分期方法,选取对预后起主要影响作用的TNM分期分层指标。在分析预后影响因素时,将病理Fuhrman分级分为两组,中将病理报告为Ⅰ级、Ⅱ级和Ⅰ-Ⅱ级划分为“高分化”组;将Ⅲ级、Ⅳ级、Ⅱ-Ⅲ级以及Ⅲ-Ⅳ级划分为“中低分化”组。手术记录中描述到“切除/清扫区域淋巴结,范围从膈肌脚至髂总血管起始处”及“切除/清扫同侧大血管周围淋巴结”即认为已施行淋巴结清扫术。依据是否行淋巴结清扫,分为清扫组和未清扫组。通过电话、走访、信访等方式了解患者的总生存时间(OS):起点为手术日期,终点为死亡的日期和疾病无进展生存期(PFS):起点为手术日期,终点为肾癌的局部复发或发现远处转移。 结果:共有252例病例纳入本研究,,行淋巴节清扫组有140例,未行淋巴节清扫组有112例。其中男性患者为162例,女性患者为90例,患者平均年龄58.23±11.96岁。随访时间为7个月~132个月,中位随访时间78个月。患者生存时间为8个月~134月,中位生存期为67个月。是否对患者进行淋巴结清扫,在生存时间(OS)上有差别(p0.01)。其中,对比TNM分期为T1-2期的患者和T3-4期的患者是否行淋巴结清扫,在无进展生存时间(PFS)上无差别(P=0.224),在总生存时间(OS)上有差别(p0.01)。生存分析显示,TNM分期为T1-2期的患者生存时间均值为107.9个月,行清扫术的患者生存时间均值为110.7个月,未行清扫术的患者生存时间均值为102.6个月,但生存分析无统计学意义(p=0.93)。T3-4期患者的生存时间均值为90.8个月,行清扫术的患者生存时间均值为100.6个月,未行清扫术的患者生存时间均值为67.7个月,生存分析有统计学意义(p0.05)。Cox回归分析显示,TNM分期、淋巴结清扫和Fuhrman分级对生存时间有显著性意义(p0.01)。 结论:在施行肾癌根治术时,对TNM分期为T1-2期的患者行淋巴结清扫术与否,对患者的生存时间无影响。而对TNM分期为T3-4期的患者行淋巴结清扫术,可以延长患者的生存时间。
[Abstract]:Objective: for a long time, whether or not to perform both lymph node dissection and the extent of lymph node dissection has been controversial. The number of urological dissection has continued to decline over the past 10 years, largely because no research has shown that lymph node dissection is certain to be beneficial, in this retrospective study. From 2003 to 2010, we collected and analyzed the data of patients who underwent radical nephrectomy and (or not) lymph node dissection in the first affiliated Hospital of Dalian Medical University, and compared the recurrence and metastasis status and survival time of the patients. To explore the significance of lymph node dissection in radical resection of renal cell carcinoma. Methods: from 2003 to 2010, 1158 patients underwent radical nephrectomy in the first affiliated Hospital of Dalian Medical University were reviewed by the electronic medical record system. The selected conditions were as follows: pathological diagnosis of renal cell carcinoma with radical renal cell carcinoma, culling conditions: other malignant tumors occurred at the same time or before treatment, there was distant metastasis during operation, and target drugs were used after operation. According to the staging method published by AJCC in 2010, the stratification index of TNM staging, which plays a major role in prognosis, was selected. In the analysis of prognostic factors, pathological Fuhrman grading was divided into two groups: grade 鈪
