摘要: 目的 探讨围手术期感染对肾细胞癌切除术后肿瘤特异性生存期(CSS)的影响。方法 以青岛大学附属医院2006年1月—2013年1月收治的1 800例肾癌患者为研究对象,分析肾癌切除术后30 d内发生感染的情况。用Kaplan-Meier曲线分析感染与未感染患者的CSS;建立Cox比例风险模型来评估感染对CSS的影响时控制性别、年龄、AJCC分期和分级、肿瘤大小、病理学类型、合并症、手术方式和系统治疗等因素。结果 1 800例患者中位年龄74岁(69~79岁),中位随访时间为42个月(22~67月)。严重感染者141例,非严重感染者296例,未感染者1 363例。Kaplan-Meier分析结果显示,严重感染有改善肾癌(肿瘤直径为7.0~9.9 cm)患者CSS趋势(P=0.048);对于肿瘤直径≥10 cm或<7 cm的患者,严重感染对CSS无影响(0.1~3.9 cm,P=0.120;4.0~6.9 cm,P=0.768;≥10 cm,P=0.412)。多因素Cox回归分析结果显示,严重感染可以改善肾癌患者的CSS(HR=0.752,P=0.032)。这种效应在肿瘤直径≥7 cm的患者中较为明显(P=0.041),而在肿瘤直径<7 cm的患者中表现得不明显(P=0.268)。结论 围手术期严重感染可以改善肿瘤直径7~10 cm的肾癌患者CSS,但是对肿瘤直径≥10 cm或<7 cm肾癌患者的CSS无明显影响。

Abstract: Objective The aim of this study was to investigate the effect of perioperative infection on cancer specific survival(CSS)after renal cell carcinoma resection.Methods A total of 1 800 patients with renal cell carcinoma from January 2006 to January 2013 in the Affiliated Hospital of Qingdao University were used as the research subjects,and the infection situation within 30 days after nephrectomy for renal cancer was analyzed.The CSS of infected and uninfected patients was analyzed by Kaplan-Meier curve,and Cox proportional hazard model was established to evaluate CSS.The factors such as sex,age,AJCC stage and classification,tumor size,pathological type,complications,surgical methods and systematic treatment were also controlled.Results The median age of 1 800 patients was 74 years(69~79 months),and the median follow-up time was 42 months(22~67 months).There were 141 cases of severe infection,296 cases of non-severe infection and 1 363 cases of non-infection.Kaplan-Meier analysis showed that severe infection had a tendency to improve CSS in patients with renal cancer(tumor diameter 7.0~9.9)(P=0.048),but severe infected patients with tumor diameter ≥10 cm or <7 cm had no effect on CSS(0.1~3.9 cm,P=0.120;4.0~6.9 cm,P=0.768;>10 cm,P=0.412).Multivariate Cox regression analysis showed that severe infection could improve CSS in patients with renal cancer(HR=0.752,P=0.032).This effect was more obvious in patients with a tumor diameter(>7 cm)(P=0.041),but it was not in patients with tumor diameter < 7 cm(P=0.268).Conclusion Severe perioperative infection can improve CSS in patients with renal cancer with a tumor diameter of 7~10 cm,but it has no effect on CSS in patients with tumors ≥10 cm or <7 cm in diameter.
