摘 要:目的 研究肾细胞癌的基本临床及病理学特征. 方法 对1956年12月至2012年8月收治的705例肾细胞癌患者进行临床及病理学分析,并回顾相关文献. 结果 肾细胞癌直径0.6~18.0 cm,平均4.6 cm.透明细胞肾细胞癌、乳头状肾细胞癌、多房性透明细胞肾细胞癌、嫌色肾细胞癌以及未分类肾细胞癌分别占88.9% (627/705)、4.1%(29/705)、3.3%(23/705)、1.3% (9/705)和2.4%(17/705).Fuhrman核分级1、2、3、4级分别占19.0%(116/612)、58.3% (357/612)、18.1%(111/612)以及4.6%(28/612).肾盂、肾周脂肪及血管侵犯者分别占10.9% (66/603)、10.6%(64/603)和4.8%(29/603).TNM分期中T1期464例(76.6%),T2期65例(10.7%),T3期73例(12.0%),T4期4例(0.7%).淋巴结和远处转移率分别为2.8%(17/606)和3.5%(21/606).Ⅰ、Ⅱ、Ⅲ、Ⅳ期肿瘤分别占74.3% (450/606)、9.9%(60/606)、11.7%(71/606)以及4.1%(25/606).3、5、10、15年肿瘤特异性生存率分别为92.8%、86.9%、76.8%和55.5%,透明细胞肾细胞癌分别为92.8%、88.1%、77.4%和55.4%.多因素分析结果显示分期是肾细胞癌唯一的独立预后因素(P=0.000).结论 肿瘤分期是肾细胞癌独立的预后因素.在肾细胞癌的诊断中应该注意肾窦侵犯和淋巴结的评价.Objective To investigate the clinicopathological features of renal cell carcinoma (RCC).Methods From December 1956 to August 2012,the clinicopathological features of RCC were studied in 705 cases and related literatures were reviewed.Results The diameter of RCC ranged from 0.6 to 18.0 cm,which the average size was 4.6 cm.The proportions of the clear cell,papillary,multilocular clear cell,chromophobe and unclassified histologic subtype were 88.9% (627/705),4.1% (29/705),3.3% (23/705),1.3% (9/705) and 2.4% (17/705),respectively.According to the Fuhrman grading system,the proportions of grade 1,2,3,4 were 19.0% (116/612),58.3% (357/612),18.1% (111/612)and 4.6% (28/612),respectively.The rates of invasion into the renal pelvis,perirenal fat and vascular were 10.9% (66/603),10.6% (64/603) and 4.8% (29/603),respectively.Of 705 cases,464 (76.6%)cases were in T1,65 (10.7%) cases in T2,73 (12.0%) cases in T3,and 4 (0.7%) cases in T4.As to the lymph node and distant metastasis,the rate was 2.8% (17/606) and 3.5% (21/606).The percentages of stage Ⅰ,Ⅱ,Ⅲ and Ⅳ RCC were 74.3% (450/606),9.9% (60/606),11.7% (71/606) and 4.1%(25/606),respectively.The 3-,5-,10-and 15-year disease-specific survival rate for RCC was 92.8%,86.9%,76.8% and 55.5%,respectively.To those patients with clear cell RCC,the disease-specific survival at the same time point was 92.8%,88.1%,77.4% and 55.4%,respectively.Multivariate analysis showed that the stage was the only independent prognostic factor for RCC.Conclusions Tumor stage of RCC is the independent prognostic factor for disease-specific survival.The evaluation of renal sinus invasion and lymph node should be noted in the diagnosis of RCC.
