Background

Hilar cholangiocarcinoma (HCCA) is a devastating malignancy arising from the bifurcation of the hepatic duct, whether combined vascular resection benefits HCCA patients is controversial. This study was undertaken to assess the effect of combined vascular resection in HCCA patients and to analyze the prognostic factors.

Methods

Clinical data of 154 HCCA patients who had been treated from January 2005 to December 2012 were retrospectively analyzed. The patients were divided into three groups based on vascular resection: those without vascular resection; those with portal vein resection alone and those with hepatic artery resection. The survival and complication rates were compared among the three groups. Multivariate analysis was made to determine prognostic factors.

Results

No significant differences were found in survival and complication rates among the three groups (P>0.05). Multivariate analysis showed that 3 factors were related to survival: lymph node metastasis, tumor size (>2.5 cm), and positive resection margin.

Conclusions

Vascular resection improved the survival rate of patients with HCCA involving the hepatic artery or portal vein. Lymph node metastasis, tumor size (>2.5 cm) and positive resection margin were poor prognostic factors in patients with HCCA.

    In addition, no subgroup analysis on patients who had undergone neoadjuvant chemotherapy prior to resection was performed, as only one study reported on this subject. Regarding adjuvant chemotherapy three studies did not report on this outcome.20,21,23 Three studies reported that patients did not receive adjuvant chemotherapy.19,22,25

    While a trend was seen towards decreasing survival with VR, there were no statistically significant differences between groups. Several subsequent single- or two-institution studies in Japan, China, and the USA have failed to discern any statistically significant differences in survival in HC patients receiving no VR, PVR, or HAR7,9,13,22 (Table 4 for more detail). Despite the multi-institutional nature of the current dataset, hilar cholangiocarcinoma remains a rare disease entity, especially in the western hemisphere.
