可切除肺癌预后预测模型的构建及生存分析

目的 探讨构建的可切除肺癌预后预测模型在患者生存及预后预测中的价值。方法 选择山西省肿瘤医院2007年1月至2018年9月原发性肺癌患者2 267例,患者均行一次肺癌手术治疗,无第二原发肿瘤。选取性别、年龄、职业、肿瘤部位、病理类型、手术路径、手术方式、肿瘤分期、治疗方案为预后影响因素。采用Cox比例风险模型构建预后指数(PI)方程,计算每例患者的PI值。根据PI值的不同范围,划分低、中、高危预后组,对各组生存情况进行评估。结果 性别(RR=0.684,P=0.001)、年龄(RR=0.591,P<0.01)、职业(RR=1.439,P=0.001)、病理类型(RR=3.694,P<0.01)、手术路径(RR=0.734,P=0.001)、肿瘤分期(RR=0.352,P=0.007)为可切除肺癌患者预后独立影响因素。其中,女性、≤65岁、胸腔镜手术、肿瘤分期Ⅰ期为预后保护因素,其预后不良风险分别降低31.6%、40.9%、26.6%、64.8%;农民、腺鳞癌为预后危险因素,其预后不良风险分别增加43.9%、269.4%。PI方程为:∑βixi=-0.380 X1-0.526 X2+0.364 X31+1.307 X55-0.309 X6-1.045 X81(X1代表性别,X2代表年龄,X31代表职业为农民,X55代表病理类型为腺鳞癌,X6代表手术路径,X81代表肿瘤分期Ⅰ期)。PI<-1为低危组,PI≥-1且≤-0.5为中危组,PI>-0.5为高危组。1、3、5年生存率低危组分别为96.8%、87.0%、77.9%,中危组分别为91.8%、82.2%、61.7%,高危组分别为86.5%、61.7%、50.3%,各组间生存率差异具有统计学意义(P<0.05)。结论 可切除肺癌预后预测模型能够预测可切除肺癌患者的预后风险及相应生存率,帮助临床医师评估预后及制订后续治疗方案。     

Surgical Technique Notes of Arterial Vascular Reconstruction During Kidney Transplantation: Personal Experience and Literature Review

Background

Arterial vascular anomalies in patients undergoing kidney transplantation (KT) are correlated with a higher incidence of early surgical complications, potentially causing graft loss. Arterial reconstruction allows patients to overcome these surgical challenges, thus minimizing the risk of poor outcomes. The aim of the present study is to retrospectively investigate the safety and effectiveness of the multiple arterial reconstruction technique with a Teflon patch in case of an unavailable aortic patch: to do so, surgical complications, graft function, and patient survival were evaluated.

Intervention for arch obstruction after the Norwood procedure: Prevalence,associated factors,and practice variability

Objective

Arch obstruction after the Norwood procedure is common and contributes to mortality. We determined the prevalence, associated factors, and practice variability of arch reintervention and assessed whether arch reintervention is associated with mortality.
