摘要:

目的 探讨术前C反应蛋白(CRP)/白蛋白(Alb)比值(CAR)和系统免疫炎症指数(SII)与浆液性卵巢癌患者临床病理特征和预后的关系。方法 选取2017年1月—2021年1月洛阳市中心医院浆液性卵巢癌患者132例。收集患者一般临床资料和术前血小板(PLT)计数、中性粒细胞(NEUT)计数、淋巴细胞(LY)计数、CRP、Alb检测结果,并计算CAR和SII。根据CAR和SII的中位数,将患者分别分为低CAR组、高CAR组和低SII组、高SII组,分析不同CAR、SII组间临床病理特征、无复发生存期(RFS)和总生存期(OS)的差异。采用单因素和多因素Cox回归分析评估浆液性卵巢癌患者RFS和OS的影响因素。结果 高CAR组和高SII组国际妇产科联盟(FIGO)分期、组织学分级、淋巴转移分别与低CAR组和低SII组比较,差异均有统计学意义(P<0.05)。高CAR组和高SII组术后残留肿瘤直径<1 cm所占比例均分别低于低CAR组和低SII组(P<0.05)。高CAR组和高SII组的RFS和OS均分别显著低于低CAR组和低SII组(P<0.05)。FIGO分期(Ⅲ期+Ⅳ期)、高CAR和高SII是影响浆液性卵巢癌患者术后RFS的独立危险因素[风险比(HR)分别为2.258、2.665、4.432,95%可信区间(CI)分别为1.125~4.534、1.401~5.069、2.227~8.821]。FIGO分期(Ⅲ期+Ⅳ期)、糖链抗原125(CA125)(≥35 U/L)、高CAR和高SII是浆液性卵巢癌患者术后OS的独立危险因素(HR分别为4.574、4.417、3.167、5.500,95%CI分别为1.660~12.607、1.426~13.686、1.392~7.206、2.254~13.424)。结论 浆液性卵巢癌患者CAR和SII与FIGO分期、组织学分级和淋巴转移等临床病理特征有关,且术前高CAR和高SII是患者预后不良的独立危险因素,可作为浆液性卵巢癌患者预后评估的参考指标。

Abstract:

Objective To investigate the relation of C-reactive protein(CRP)-to-albumin(Alb) ratio(CAR) and systemic immune-inflammation index(SII) with pathological characteristics and prognosis of serous ovarian cancer patients. Methods A total of 132 patients with serous ovarian cancer were enrolled from Luoyang Central Hospital from January 2017 to January 2021. The general clinical data and preoperative platelet(PLT) count,neutrophil(NEUT) count,lymphocyte(LY) count,CRP,Alb determination results were collected,and CAR and SII were calculated. According to the medians of CAR and SII,the patients were classified into low CAR group,high CAR group and low SII group,high SII group,respectively. The differences of pathological characteristics,recurrence free survival(RFS) and overall survival(OS) among different CAR and SII groups were analyzed. Both univariate and multivariate Cox regression models were used to analyze the influencing factors of RFS and OS in patients with serous ovarian cancer. Results The International Federation of Gynecology and Obstetrics(FIGO) stage,histological grade and lymphatic metastasis in high CAR group and high SII group had statistical significance with those in low CAR group and low SII group,respectively(P<0.05). The proportions of residual tumor diameter <1 cm in high CAR group and high SII group were lower than those in low CAR group and low SII group,respectively(P<0.05). The RFS and OS of high CAR group and high SII group were lower than those of low CAR group and low SII group,respectively(P<0.05). FIGO stage(Ⅲ+Ⅳ),high CAR and high SII were independent risk factors for postoperative RFS in patients with serous ovarian cancer [hazard ratios(HR) were 2.258,2.665 and 4.432,95% confidence intervals(CI) were 1.125-4.534,1.401-5.069 and 2.227-8.821,respectively]. FIGO stage(Ⅲ+Ⅳ),carbohydrate antigen 125(CA125)(≥35 U/L),high CAR and high SII were independent risk factors for postoperative OS in patients with serous ovarian cancer(HR were 4.574,4.417,3.167 and 5.500,95%CI 1.660-12.607,1.426-13.686,1.392-7.206 and 2.254-13.424,respectively). Conclusions CAR and SII in patients with serous ovarian cancer are related to FIGO stage,histological grade and lymphatic metastasis,and preoperative high CAR and SII are independent risk factors for poor prognosis of patients with serous ovarian cancer,which can be used as reference indexes for the prognosis evaluation of patients with serous ovarian cancer.
