摘　　要：目的:探究肾周脂肪CT参数对肾癌诊断和预后的临床意义和预测价值。方法:收集蚌埠医学院第一附属医院泌尿外科肾癌患者91例,同时收集50例肾囊肿患者作为对照。记录2组患者一般临床资料、MAP评分、肾周脂肪CT值、厚度和面积等资料,寻找对肾癌诊断具有临床意义的指标并分析其与肾癌患者预后的相关性。结果:2组患者的患侧肾周脂肪面积及手术时间比较差异有统计学意义(P<0.05)。回归分析结果显示,患侧肾周脂肪面积与肾癌相关(P<0.05),且为肾癌发生的独立危险因素。ROC曲线分析结果显示,在肾癌组与肾囊肿组中,最佳临界值为14.575,灵敏度为63.7%,特异度为64.0%,约登指数为0.277,ROC曲线下面积为0.634。在肾癌复发组与未复发组中,最佳临界值为21.485,灵敏度为100.0%,特异度为65.5%,约登指数为0.655,ROC曲线下面积为0.731。免疫组化结果表明高面积组解偶连蛋白1(uncoupling protein 1,UCP-1)表达显著高于低面积组。结论:本研究证实患侧肾周脂肪面积在肾癌诊断及预后判断方面具有一定的临床价值,值得关注并推广。Objective To explore the clinical significance and predictive value of perirenal fat CT parameters in the diagnosis and prognosis of renal carcinoma.Methods We collected 91 patients with renal carcinoma,and 50 patients with renal cyst were collected as control.The general clinical data,MAP score,CT value of perirenal fat,thickness and area of patients were recorded to find clinically significant indicators for the diagnosis of renal cancer and analyze their correlation with the prognosis of patients with renal cancer.Results The perirenal fat area and operation time of the two groups were statistically significant(P<0.05).The results of regression analysis showed that perirenal fat area was correlated with renal cancer(P<0.05),and was also an independent risk factor for renal cancer.ROC curve analysis results showed that the optimal cut-off value was 14.575.The sensitivity was 63.7%,and the specificity was 64.0%.The Youden index was 0.277,and the area under ROC curve was 0.634 in the renal carcinoma group and the renal cyst group.In renal cancer recurrence group and non-recurrence group,the optimal cut-off value was 21.485.The sensitivity was 100.0%,and the specificity was 65.5%.The Youden index was 0.655,and the area under ROC curve was 0.731.Immunohistochemical results showed that UCP-1 expression in high area group was significantly higher than that in low area group.Conclusion This study confirmed that the perirenal fat area of the affected side has certain clinical value in the diagnosis and prognosis of renal cancer,which is worthy of attention and promotion.
