BACKGROUND: Resection outcomes for perihilar cholangiocarcinoma differ between Western and Eastern centres, but reasons behind these disparities remain unclear. This study aimed to compare current outcomes between a Western and an Eastern expert centre to identify prognostic factors.
METHODS: Patients who underwent hepatobiliary resection for perihilar cholangiocarcinoma between 2010 and 2022 at Karolinska University Hospital (Stockholm, Sweden) and Cancer Institute Hospital (Tokyo, Japan) were retrospectively included. Primary outcome was overall survival. Secondary outcomes were disease-free survival, postoperative complications and 90-day mortality rate.
RESULTS: Two hundred and forty-nine patients were included (Cancer Institute Hospital n = 159, Karolinska n = 90). Median overall survival was 20.4 months at Karolinska and 52.0 months at Cancer Institute Hospital (P < 0.001). Median disease-free survival was 11.9 months at Karolinska and 32.4 months at Cancer Institute Hospital (P < 0.001). Advanced tumours, ASA class ≥III, poor differentiation and radial margin positivity were more common in the Western cohort. Treatment centre, T-status, N1-status, resection side, R1-status, age and carbohydrate antigen 19-9 were prognostic for overall survival. The Eastern cohort had a lower rate of postoperative complications (24.5%) and a lower mortality rate (2.5%) compared with the Western cohort (51.1% and 10.0%).
CONCLUSION: Advanced tumour stage and radial margin positivity contributed to poor long-term survival in the Western cohort. A higher burden of co-morbidity and a higher rate of extended resections with smaller remnant liver volume influenced the Western postoperative mortality rate.
