Prognosis value of microscopic bile duct invasion in hepatocellular carcinoma: A multicenter study.

ABSTRACT:

Objective

To evaluate the prognostic significance of microscopic bile duct invasion (MiBDI) in hepatocellular carcinoma (HCC) following R0 resection.

Patients and methods

Patients who underwent R0 resection for HCC at nine medical centers were stratified into five groups: neither bile duct nor vascular invasion (MiBDI-MVI-), microscopic bile duct invasion alone (MiBDI+MVI-), both microscopic bile duct and vascular invasion (MiBDI+MVI+), microscopic vascular invasion alone (MiBDI-MVI+), and macroscopic bile duct invasion (MaBDI). Overall survival (OS) was assessed using Kaplan-Meier analysis, and independent risk factors of OS were determined using Cox proportional hazards models.

Results

A total of 377 HCC cases were analyzed. The OS for MiBDI+MVI- was similar to that of MiBDI-MVI- (p > 0.05) but better than MiBDI+MVI+, MiBDI-MVI+, and MaBDI (all p < 0.05). Multivariate analysis indicated that MiBDI was not an independent risk factor for OS, while MVI and MaBDI were.

Conclusions

Overall survival (OS) in patients with MiBDI was superior to those with MVI and MaBDI. Isolated MiBDI did not influence OS in patients with HCC after R0 resection.

Project description:BackgroundThe assessment of tumor-infiltrating lymphocytes (TILs) has led to the development of various immunotherapies beyond their predictive potential in gastrointestinal malignancies. However, the clinicopathologic and prognostic values of TILs have yet to be well elucidated in distal extrahepatic bile duct carcinoma (DBDC).Patients and methodsWe evaluated stromal TILs (sTILs) and intraepithelial TILs (iTILs) in 405 surgically resected DBDCs to analyze their correlations with overall survival (OS) and recurrence-free survival (RFS) and with clinicopathologic parameters according to the eighth edition of the American Joint Committee on Cancer scheme.ResultsHigh levels of sTIL density (sTILHigh; >5%) and iTIL count (iTILHigh; >3) were found in 245 (61%) and 74 cases (18%), respectively. sTILHigh was more commonly found in larger tumors (P = 0.048) diffusely involving both intra- and extrapancreatic bile ducts (P = 0.013), in tumors with lower T category (P = 0.002), and in tumors without pancreatic (P = 0.003) or duodenal invasion (P < 0.001). iTILHigh was associated with tumors with papillary or nodular growth pattern (P < 0.001) without perineural invasion (P = 0.006). Both sTILHigh and iTILHigh significantly predicted better OS (P = 0.009 and 0.036, respectively) and RFS (P = 0.003 and 0.026, respectively). sTIL consistently provided prognostic predictability in OS, even when tested with different quantitative cut-offs and prognostically stratified OS (P = 0.006) and RFS (P = 0.005) on multivariate analysis. The survival benefit of sTILHigh persisted regardless of the stage in both OS (P = 0.010 for lower stages I and II and P = 0.001 for higher stages III and IV) and RFS (P = 0.004 and 0.025 for lower- and higher-stage tumors, respectively).ConclusionssTILs were superior to iTILs in predicting survival, and it was shown to be a strong prognosticator for DBDC patients regardless of the stage. The utility of sTILs may extend beyond prognostication to aid in predicting therapeutic responses in DBDC patients.

Project description:BackgroundHepatocellular carcinoma (HCC) associated with bile duct tumor thrombus (BDTT) is uncommon in clinical practice. Surgical resection can achieve better survival than non-operative palliative treatments. However, there is great controversy regarding the optimal surgical modality, particularly regarding the approach to remove BDTT in patients with HCC with macroscopic BDTT.MethodsData from consecutive patients who underwent radical surgery for HCC and macroscopic BDTT at the Eastern Hepatobiliary Surgery Hospital and Fujian Provincial Hospital from January 2009 to December 2016 were retrospectively reviewed. The survival outcomes of patients who underwent hepatectomy combined with extrahepatic bile duct resection (the EBDR group) were compared with those of patients undergoing liver resection plus thrombectomy (the thrombectomy group) using propensity score matching (PSM). Univariate and multivariate Cox analyses were performed to identify independent prognostic factors for overall survival (OS) and recurrence-free survival (RFS).Results217 patients included in this study were divided into two groups: the EBDR group (n=30) and the thrombectomy group (n=187). A total of 90 patients were matched by PSM with a 1:2 ratio. Before PSM, the OS and RFS rates were comparable between the two groups (for OS, P=0.517; for RFS, P=0.211). After PSM, the OS rates did not differ statistically significantly between the EBDR and thrombectomy groups (P=0.134). Nevertheless, the RFS rate of the EBDR group was significantly higher compared to that of the thrombectomy group (P=0.020). Multivariate analysis demonstrated that some traditional risk factors, such as tumor size and microscopic resection margin, were more important prognostic factors than the BDTT type.ConclusionsFor patients with HCC and macroscopic BDTT, hepatectomy combined with extrahepatic bile duct resection is associated with a reduced recurrence rate in comparison with concurrent thrombectomy. Further large-scale, prospective studies are warranted to evaluate the impact of different surgical modalities on these patients' survival.
