Background Perihilar cholangiocarcinoma (pCCA) is a rare tumour that requires complex multidisciplinary management. All known data are almost exclusively derived from expert centres. This study aimed to analyse the outcomes of patients with pCCA in a nationwide cohort. Methods Data on all patients diagnosed with pCCA in the Netherlands between 2010 and 2018 were obtained from the Netherlands Cancer Registry. Data included type of hospital of diagnosis and the received treatment. Outcomes included the type of treatment and overall survival. Results A total of 2031 patients were included and the median overall survival for the overall cohort was 5.2 (95% CI 4.7‐5.7) months. Three‐hundred‐ten (15%) patients underwent surgical resection, 271 (13%) underwent palliative systemic treatment, 21 (1%) palliative local anti‐cancer treatment and 1429 (70%) underwent best supportive care. These treatments resulted in a median overall survival of 29.6 (95% CI 25.2‐34.0), 12.2 (95% CI 11.0‐13.3), 14.5 (95%CI 8.2‐20.8) and 2.9 (95% CI 2.6‐3.2) months respectively. Resection rate was 13% in patients who were diagnosed in non‐academic and 32% in academic centres (P < .001), which resulted in a survival difference in favour of academic centres. Median overall survival was 9.7 (95% CI 7.7‐11.7) months in academic centres compared to 4.9 (95% CI 4.3‐5.4) months in non‐academic centres (P < .001). Conclusions In patients with pCCA, resection rate and overall survival were higher for patients who were diagnosed in academic centres. These results show population‐based outcomes of pCCA and highlight the importance of regional collaboration in the treatment of these patients.
Background: The aim of this study was to investigate the incidence and risk factors of primary and secondary liver failure after major liver resection for perihilar cholangiocarcinoma. Methods: All patients who underwent a major liver resection for presumed perihilar cholangiocarcinoma between 2000 and 2020 at 2 tertiary-referral hospitals were included. Liver failure was defined according to the International Study Group for Liver Surgery criteria, and only grade B/C was considered clinically relevant. Primary liver failure was defined as failure without any underlying postoperative cause, and secondary liver failure was defined as liver failure with an onset after an underlying postoperative complication as a cause. Results: The incidence of liver failure and 90-day mortality were 20.9% and 17.0% in the 253 included patients, respectively. The incidences of primary liver failure was 9.1% and secondary liver failure was 11.9%. Abdominal sepsis, portal vein thrombosis, and arterial thrombosis were the most frequent causes. The absence of preoperative remnant liver assessment and blood loss were independent risk factors for primary liver failure. Independent risk factors for secondary liver failure were Eastern Cooperative Oncology group performance status, percutaneous biliary drainage, and preoperative cholangitis. Conclusion: Liver failure after major liver resection for perihilar cholangiocarcinoma occurred in 1 of every 5 patients. The proposed subdivision into primary and secondary liver failure could help to understand differences in outcomes between centers and help to reduce liver failure.
Background The risk of death after surgery for perihilar cholangiocarcinoma is high; nearly one in every five patients dies within 90 days after surgery. When the oncological benefit is limited, a high-risk resection may not be justified. This retrospective cohort study aimed to create two preoperative prognostic models to predict 90-day mortality and overall survival (OS) after major liver resection for perihilar cholangiocarcinoma. Methods Separate models were built with factors known before surgery using multivariable regression analysis for 90-day mortality and OS. Patients were categorized in three groups: favourable profile for surgical resection (90-day mortality rate below 10 per cent and predicted OS more than 3 years), unfavourable profile (90-day mortality rate above 25 per cent and/or predicted OS below 1.5 years), and an intermediate group. Results A total of 1673 patients were included. Independent risk factors for both 90-day mortality and OS included ASA grade III–IV, large tumour diameter, and right-sided hepatectomy. Additional risk factors for 90-day mortality were advanced age and preoperative cholangitis; those for long-term OS were high BMI, preoperative jaundice, Bismuth IV, and hepatic artery involvement. In total, 294 patients (17.6 per cent) had a favourable risk profile for surgery (90-day mortality rate 5.8 per cent and median OS 42 months), 271 patients (16.2 per cent) an unfavourable risk profile (90-day mortality rate 26.8 per cent and median OS 16 months), and 1108 patients (66.2 per cent) an intermediate risk profile (90-day mortality rate 12.5 per cent and median OS 27 months). Conclusion Preoperative risk models for 90-day mortality and OS can help identify patients with resectable perihilar cholangiocarcinoma who are unlikely to benefit from surgical resection. Tailored shared decision-making is particularly essential for the large intermediate group.
