摘要
目的探讨手术治疗早期子宫颈癌患者(ⅠB~ⅡA期)术中失血量的影响因素。方法回顾性分析2010年12月至2017年9月于四川大学华西第二医院住院手术治疗的早期子宫颈癌患者892例,分为两组,术中失血量≥500mL组127例,失血量<500mL组765例。收集患者临床病理资料,包括一般资料、有无盆腹腔手术史、肿瘤直径、病理类型、有无淋巴结转移、临床分期、手术方式、是否新辅助化疗(neoadjuvant chemotherapy,NACT)、NACT后手术时机选择、术前及术后血红蛋白、术中失血量及术中输血量等,多因素logistic回归分析该人群术中失血量的独立危险因素并进行危险分层。结果两组患者年龄、体质量指数(BMI)、妊娠次数、盆腔手术史占比、慢性盆腔炎史占比、子宫颈癌临床分期、手术方式、是否行NACT及NACT后手术时机差异均有统计学意义(P<0.05)。多因素logistic回归分析结果显示,患者年龄≥40岁[偏回归系数(B)=2.100)]、BMI≥24kg/m2(相对于18.5~23.9kg/m2)(B=1.842)、临床分期为ⅡA期(相对于ⅠB期)(B=2.401)、手术方式为开腹手术(相对于腹腔镜)(B=1.347)、未行NACT(B=1.540)、于NACT后<2周及>3周手术(相对于2~3周内手术)(B=1.723)是术中失血量大(≥500mL)的独立危险因素。结论肿瘤临床分期和年龄等是早期子宫颈癌患者术中失血量大的独立影响因素。
Objective To determine risk factors associated with intraoperative blood loss in patients with early cervical cancer(stageⅠB-ⅡA).Methods The medical records of 892 patients who underwent surgical treatments for early cervical cancer in the Second West China University Hospital of from Dec 2010 to Sep 2017 were retrospectively reviewed:127having≥500mL intraoperative blood loss patients compared with 765 less than 500 mL.Differences between the two groups in age,body mass index(BMI),gravidity,history of abdominal and pelvic operations,chronic pelvic inflammation disease,clinical stage,methods of operation,neoadjuvant chemotherapy(NACT)and post-NACT operative opportunity,preoperative and postoperative hemoglobin,and intraoperative transfusion volume were analyzed through univariate and multivariate statistical methods.Results The univariate analyses identified age,BMI,gravidity,history of abdominal and pelvic operation,chronic pelvic inflammation disease,clinical stage,methods of operation,NACT and post-NACT operative opportunity assignificant factors associated with intraoperative blood loss(P<0.05).The multivariate logistic regression analysis confirmed that age≥40yr.[partial regression coefficient(B)=2.100)],BMI ≥24kg/m2(relative to 18.5-23.9kg/m2)(B=1.842),clinical stage ⅡA(relative to phase ⅠB,B=2.401),trans-abdominal operative method(relative to laparoscopy,B=1.347),no NACT(B=1.540)and post-NACT operative opportunity<2or>3weeks(relative to within 2-3weeks)(B=1.723)were independent predictors of higher intraoperative blood loss(≥500 mL).Conclusion Clinical stage and age,etc.are risk factors associated with intraoperative blood loss in patients with early cervical cancer.
