Abstract:

Objective

To explore the predictive value of tumor burden score (TBS) combined with lymph node staging (TBS-N staging) for postoperative survival of patients with intrahepatic cholangiocarcinoma (ICC).

Methods

Clinical data of 335 ICC patients who underwent hepatectomy in Zhongda Hospital of Southeast University School of Medicine, Eastern Hepatobiliary Surgery Hospital and Affiliated Hospital of North Sichuan Medical College from January, 2013 to December, 2019 were retrospectively analyzed. Among them, 169 patients were male and 166 female, aged from 23 to 87 years, with a median age of 62 years. The informed consents of all patients were obtained and the local ethical committee approval was received. The TBS of all patients was calculated. All the patients were divided into stageⅠ, Ⅱ and Ⅲ according to TBS score and lymph node metastasis. The predictive ability of TBS-N staging for clinical prognosis of ICC patients after hepatectomy was analyzed by the receiver operating characteristic (ROC) curve. The risk factors of clinical prognosis of ICC patients after hepatectomy were identified by Cox proportional hazard regression model.

Results

The optimal cut-off value of TBS was 4.22, including84 cases of TBS-N stageⅠ, 202 cases of stageⅡand 49 cases of stage Ⅲ. TBS-N staging was correlated with tumor diameter (F=77.639, P<0.05), intraoperative blood loss (Z=11.385, P<0.05), HBV infection rate (χ2=6.590, P<0.05), surgical resection range (χ2=9.796, P<0.05), vascular invasion (χ2=12.332, P<0.05), TNM staging (P<0.05) and postoperative complications (χ2=7.210, P<0.05) of ICC patients. Cox multivariate analysis showed that TBS>4.22, N1 stage and poor tumor differentiation were the independent risk factors for clinical prognosis of ICC patients after hepatectomy (HR=1.529, 2.100, 1.724; P<0.05). The median overall survival of patients with TBS-N stage Ⅰ, Ⅱ and Ⅲ was 51.4, 22.7 and 12.0 months, respectively, where significant differences were observed (χ2=25.797, P<0.05). The area under ROC curve (AUC) of TBS, N staging and TBS-N model for predicting clinical prognosis of ICC patients after hepatectomy was 0.596, 0.602 and 0.660, respectively.

Conclusions

TBS and N staging are the independent risk factors for clinical prognosis of ICC patients after hepatectomy. Compared with TBS or N staging alone, TBS-N staging can better evaluate the clinical prognosis of ICC patients after hepatectomy.
