Objective: To investigate the association between prealbumin and the long-term prognosis of patients with hilar cholangiocarcinoma(HCCA) following radical surgery. Methods: The clinical data of 262 HCCA patients who underwent radical surgery admitted from January 2010 to January 2017 at the First Affiliated Hospital of Army Medical University were collected,retrospectively. There were 158 males and 104 females; aged (57.6±9.9)years old(range:32 to 78 years). According to the preoperative serum prealbumin level(170 mg/L),the patients were divided into low prealbumin group(n=143) and normal prealbumin group(n=119). Follow-up until September 2020,the main research indicator was overall survival(OS), and the secondary research indicator was recurrence-free survival(RFS). The measurement data conforming to the normal distribution adopted the t test,the measurement data not conforming to the normal distribution adopted the Mann-Whitney U test,and the count data adopted the χ2 test. The Kaplan-Meier method was used to calculate the cumulative survival rate. The Log-rank test was used for univariate analysis of the cumulative survival rate. Variables with P<0.10 in univariate analysis were included in the Cox proportional hazards model for multivariate analysis. Results: The 1-, 3-, and 5-year OS rate of the 262 patients was 73.4%, 32.1%, and 24.0%, respectively, and the 1-, 3-, and 5-year RFS rate was 54.6%, 25.2%, and 16.2%, respectively. Median OS and RFS were 21 months and 12 months for patients with low prealbumin and 25 months and 19 months for patients with normal prealbumin. The OS rate and RFS rate of patients in the low prealbumin group were lower than those in the normal prealbumin group, and the difference was statistically significant (both P<0.05). The results of univariate analysis indicated that low prealbumin, CA19-9>150 U/L, tumor infiltration length>3 cm, preoperative jaundice, macrovascular invasion, microvascular invasion, lymph node metastasis, and poor differentiation maybe the risk factors of OS,and low prealbumin,tumor invasion length>3 cm,macrovascular invasion, microvascular invasion,lymph node metastasis,and poor differentiation maybe the risk factors of RFS for postoperative for radical resection in patients with HCCA (all P<0.10). Multivariate results suggested that low prealbumin,tumor invasion length>3 cm,microvascular invasion,lymph node metastasis,and poor differentiation were independent risk factors affecting OS and RFS in patients with HCCA after radical operation (all P<0.05). Conclusion: Preoperative prealbumin level can predict the long-term prognosis of patients with hilar cholangiocarcinoma following radical surgery.
目的： 探讨术前前白蛋白水平与肝门部胆管癌（HCCA）根治性切除术后患者长期预后的关系。 方法： 回顾性收集陆军军医大学第一附属医院2010年1月至2017年1月收治的262例接受根治性手术的HCCA患者的临床和病理学资料。男性158例，女性104例；年龄（57.6±9.9）岁（范围：32~78岁）。以术前前白蛋白水平为170 mg/L为界，将患者分为低前白蛋白组（n=143）和正常前白蛋白组（n=119）。随访至2020年9月，主要研究指标为总体生存（OS）时间，次要研究指标为无复发生存（RFS）时间。符合正态分布的定量资料采用t检验进行比较分析，不符合正态分布的定量资料采用Mann-Whitney U检验进行比较分析，分类资料采用χ2检验进行比较分析。采用Kaplan-Meier法计算累积生存率。采用Log-rank检验对累积生存率进行单因素分析。将单因素分析中P<0.10的变量纳入Cox比例风险模型进行多因素分析。 结果： 262例患者的1、3、5年OS率分别为73.4%、32.1%、24.0%，1、3、5年RFS率分别为54.6%、25.2%、16.2%。低前白蛋白组患者的中位OS时间和中位RFS时间分别为21个月和12个月，正常前白蛋白患者的中位OS时间和中位RFS时间分别为25个月和19个月。低前白蛋白组患者的OS率和RFS率均低于正常前白蛋白组，差异均有统计学意义（P值均<0.05）。单因素分析结果提示，前白蛋白水平低、CA19-9>150 U/L、肿瘤浸润长度>3 cm、术前减黄、大血管侵犯、微血管侵犯、淋巴结转移、低分化可能是HCCA患者根治性切除术后OS的预后因素（P值均<0.10），前白蛋白水平低、肿瘤浸润长度>3 cm、大血管侵犯、微血管侵犯、淋巴结转移、低分化是HCCA患者根治性切除术后RFS的预后因素（P值均<0.10）。多因素分析结果提示，前白蛋白水平低、肿瘤浸润长度>3 cm、微血管侵犯、淋巴结转移、低分化是影响肝门部胆管癌患者根治性切除术后OS和RFS的独立预后因素（P值均<0.05）。 结论： 术前前白蛋白水平可预测肝门部胆管癌根治性切除术后患者的长期预后。.
