目的

探讨肝切除联合淋巴结清扫对临床淋巴结阴性的肝内胆管癌（ICC）患者预后的价值。

方法

回顾性分析2010年1月至2018年2月川北医学院附属医院行根治性手术切除的142例临床淋巴结阴性ICC患者临床资料。患者均签署知情同意书，符合医学伦理学规定。其中男77例，女65例；年龄23～78岁，中位年龄57岁。根据术中是否行淋巴结清扫分为淋巴结清扫组（LND组，86例）和非淋巴结清扫组（NLND组，56例），LND组根据术后病理提示进一步分为有淋巴结转移组（N1组，38例）和无淋巴结转移（N0组，48例），分析淋巴结清扫对ICC患者预后的影响。生存分析采用Kaplan-Meier法和Log-rank检验。

结果

NLND、LND组行半肝切除和（或）尾状叶及肝外胆管切除分别为20、71例，LND组切除范围更大（χ²=29.233，P<0.05）。LND组术后平均住院时间为（19±10）d，明显长于NLND组的（16±5）d（t=3.961，P<0.05）。LND组1、3、5年累积生存率分别为82%、42%、20%，NLND组相应为89%、47%、34%，两组总体生存差异无统计学意义（χ²=0.846，P>0.05）。N1组1、3、5年累积生存率为63%、14%、0，N0组相应为93%、57%、28%。NLND组与N1组比较差异有统计学意义（χ²=9.525，P<0.05），而NLND组与N0组比较差异无统计学意义（χ²=0.300，P>0.05）。

结论

淋巴结清扫对临床淋巴结阴性ICC患者预后无明显改善，且增加了住院时间，应慎重考虑常规施行淋巴结清扫。

Objective

To evaluate the prognostic value of hepatectomy combined with lymph node dissection (LND) in intrahepatic cholangiocarcinoma (ICC) patients with clinical negative lymph node metastasis.

Methods

Clinical data of 142 ICC patients with negative lymph node metastasis who underwent radical resection in the Affiliated Hospital of North Sichuan Medical College from January 2010 to February 2018 were retrospectively analyzed. The informed consents of the patients were obtained and the local ethical committee approval was received. Among them, 77 patients were male and 65 female, aged 23-78 years witha median age of 57 years. According to whether LND was performed during operation, all patients were divided into the LND group (n=86) and non-LND (NLND) group (n=56). Patients in LND group were further divided into the lymph node metastasis (N1) group (n=38) and non-lymph node metastasis (N0) group (n=48) according to postoperative pathological findings. The effect of LND upon the prognosis of ICC patients was evaluated. Survival analysis was performed by Kaplan-Meier survival curve and Log-rank test.

Results

In NLND and LND groups, 20, 71 cases underwent hemihepatectomy and/or resection of caudate lobe, extrahepatic bile duct, respectively. The resection range in LND group was significantly larger than that in NLND group (χ2=29.233, P<0.05). The mean length of postoperative hospital stay in LND group was (19±10) d, significantly longer than (16±5) d in NLND group (t=3.961, P<0.05). The 1-, 3- and 5-year cumulative survival rates in LND group were 82%, 42% and 20%, which did not significantly differ from 89%, 47% and 34% in NLND group (χ2=0.846, P>0.05). In N1 group, the 1-, 3-, and 5-year cumulative survival rates were 63%, 14% and 0, and were 93%, 57% and 28% in N0 group.Significant difference was observed between the NLND and N1 groups (χ2=9.525, P<0.05), whereas no significant difference was observed between the NLND and N0 groups (χ2=0.300, P>0.05).

Conclusions

LND does not improve the clinical prognosis of ICC patients with clinical negative lymph nodes metastasis, whereas it increases the length of hospital stay. Routine LND should be performed with discretion.
