不同淋巴结分期指标评估肝内胆管癌患者预后的价值探讨

Application value of different lymph node staging system in predicting prognosis of patients with intrahepatic cholangiocarcinoma

摘要:

目的:探讨阳性淋巴结数目(NMLN)、阳性淋巴结比例(LNR)、阳性淋巴结对数比(LODDS)在评估肝内胆管癌(ICC)患者预后中的价值。方法:收集2010年1月至2018年12月中国10家三甲医院肝胆外科中心行意向性根治性手术治疗的440例ICC患者的临床病理学资料。其中男性205例,女性235例;年龄(57.0±9.9)岁(范围:23~83岁)。85例(19.3%)合并肝内胆管结石,98例(22.3%)合并慢性病毒性肝炎。随访截至2019年4月30日。采用Kaplan-Meier法计算累积总体生存率,生存分析中单因素分析采用Log-rank检验,多因素分析使用Cox检验。结果:440例患者均接受意向性根治性切除治疗,其中R0切除424例(96.4%),R1切除16例(3.6%)。所有患者均接受淋巴结清扫。术后病理学检查结果显示,高分化比例为4.2%(18/426),中分化比例为60.6%(258/426),低分化比例为35.2%(150/426);腺癌比例为90.2%(397/440),非腺癌比例为9.8%(43/440);Tis期2例(0.5%),T1a期83例(18.9%),T1b期97例(22.0%),T2期95例(21.6%),T3期122例(27.7%),T4期41例(9.3%)。所有患者的总体中位生存时间为24.0个月,1、3、5年累积总体生存率分别为74.3%、37.7%、18.3%。175例(39.8%)患者出现淋巴转移,清扫淋巴结[ M( Q R)]6(5)枚,NMLN为0(1)枚,LNR为0(0.33),LODDS为-0.70(-0.92)。单因素分析结果显示,有无结石、分化程度、有无血管侵犯、LODDS、切缘、T分期是影响患者的预后因素( P值均<0.05)。进一步的Cox多因素回归模型分析结果显示,分化程度、切缘、T分期、LODDS为患者的独立预后因素( P值均<0.05)。 结论:LODDS可作为ICC患者淋巴结转移的分期指标,同时也是患者的独立预后因素。

Objective:To examine the value of number of metastatic lymph nodes(NMLN), lymph node ratio(LNR) and log odds of metastatic lymph nodes(LODDS) in assessing the prognosis of patients with intrahepatic cholangiocarcinoma(ICC).Methods:The clinical and pathological data of 440 ICC patients who underwent curative-intent resection in 10 of Chinese hepatobiliary surgery centers from January 2010 to December 2018 were collected, and the deadline of follow-up was April 30th, 2019. Among them, 205 were males and 235 were females, with age of (57.0±9.9) years (range:23-83 years).Eighty-five cases (19.3%) had intrahepatic bile duct stones, and 98 cases (22.3%) had chronic viral hepatitis.The Kaplan-Meier method was used for survival analysis. The univariate and multivariate analysis were implemented respectively using the Log-rank test and Cox proportional hazard model.Results:A total of 440 patients underwent curative-intent resection and lymphadenectomy.R0 resection were achieved in 424 cases (96.4%) and R1 resection were in 16 cases (3.6%). The results of postoperative pathological examination showed that high, moderate and poor differentiation was 4.2%(18/426), 60.6%(258/426) and 35.2%(150/426), respectively.Adenocarcinoma was seen in 90.2%(397/440) and non-adenocarcinoma was seen in 9.8%(43/440), respectively. T stage: 2 cases (0.5%) with Tis, 83 cases(18.9%) with T1a, 97 cases(22.0%) with T1b, 95 cases(21.6%) with T2, 122 cases (27.7%) with T3 and 41 cases(9.3%) with T4.The overall median survival time was 24.0 months, and the 1-,3-, and 5-year survival rate was 74.3%, 37.7% and 18.3%, respectively. Lymphatic metastasis occurred in 175 patients(39.8%), the median total number of TNLE( M( Q R)) was 6(5), the median number of NMLN was 0(1), the median number of LNR was 0 (0.33) and the median number of LODDS was -0.70(-0.92). Rerults of univariate analysis showed that combined stones, pathological differentiation, vascular invasion, LODDS, margin and T staging affected the prognosis (all P<0.05). Rerults of multivariate analysis showed that pathological differentiation, LODDS, margin, and T staging were independent risk factors affecting the prognosis of ICC patients (all P<0.05). Conclusion:LODDS could be used as an optimal prognostic lymph node staging index for ICC, and it is also an independent risk factor for survival after curative intent resection.
