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.
The patients with unresectable perihilar cholangiocarcinoma require biliary drainage to relieve symptoms and allow for palliative systemic chemotherapy. The aim of this study was to establish the ...success, complication, and mortality rates of the initial biliary drainage in patients with unresectable perihilar cholangiocarcinoma at presentation.
In this retrospective multicenter study, patients with unresectable perihilar cholangiocarcinoma who underwent initial endoscopic or percutaneous transhepatic biliary drainage between 2002 and 2014 were included. The success of drainage was defined as a successful biliary stent or drain placement, no unscheduled reintervention within 14 days, and serum bilirubin levels <50 μmol/L (ie, 2.9 mg/dL) or a >50% decrease in serum bilirubin after 14 days. Severe complications, and 90-day mortality were recorded.
Included were 186 patients: 161 (87%) underwent initial endoscopic biliary drainage and 25 (13%) underwent initial percutaneous transhepatic biliary drainage. The success of initial drainage was observed in 73 patients (45%) after endoscopic biliary drainage and 6 (24%) after percutaneous transhepatic biliary drainage. The reasons for an unsuccessful initial drainage were: the failure to place a drain or stent in 39 patients (21%), an unplanned reintervention within 14 days in 52 patients (28%), and the bilirubin level >50 μmol/L (or not halved) after 14 days of initial drainage in 16 patients (9%). Severe drainage-related complications occurred in 19 patients (12%) after endoscopic biliary drainage and in 3 (12%) after percutaneous transhepatic biliary drainage. Overall, 66 patients (36%) died within 90 days after initial biliary drainage.
Initial biliary drainage in patients with unresectable perihilar cholangiocarcinoma had a success rate of 45% and a 90-day mortality rate of 36%. Future studies for patients with perihilar cholangiocarcinoma should focus on improving biliary drainage.
Abstract
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.
When the oncological benefit is limited, a high-risk resection may be not be justified. Two preoperative prognostic models were created to predict 90-day mortality and survival after major liver resection for perihilar cholangiocarcinoma. These can help identify patients with resectable perihilar cholangiocarcinoma who are unlikely to benefit from surgical resection.
Evaluation of morbidity and mortality after hepatic resection often lacks stratification by extent of resection or diagnosis. Although a liver resection for different indications may have technical ...similarities, postoperative outcomes differ. The aim of this systematic review and meta-analysis was to determine the risk of major complications and mortality after resection of intrahepatic cholangiocarcinoma.
Meta-analysis was performed to assess postoperative mortality (in-hospital, 30-, and 90-day) and major complications (Clavien-Dindo grade ≥III).
A total of 32 studies that reported on 19,503 patients were included. Pooled in-hospital, 30-day, and 90-day mortality were 5.9% (95% confidence interval 4.1–8.4); 4.6% (95% confidence interval 4.0–5.2); and 6.1% (95% confidence interval 5.0–7.3), respectively. Pooled proportion of major complications was 22.2% (95% confidence interval 17.7–27.5) for all resections. The pooled 90-day mortality was 3.1% (95% confidence interval 1.8–5.2) for a minor resection, 7.4% (95% confidence interval 5.9–9.3) for all major resections, and 11.4% (95% confidence interval 6.9–18.7) for extended resections (P = .001). Major complications were 38.8% (95% confidence interval 29.5–49) after a major hepatectomy compared to 11.3% (95% confidence interval 5.0–24.0) after a minor hepatectomy (P = .001). Asian studies had a pooled 90-day mortality of 4.4% (95% confidence interval 3.3–5.9) compared to 6.8% (95% confidence interval 5.6–8.2) for Western studies (P = .02). Cohorts with patients included before 2000 had a pooled 90-day mortality of 5.9% (95% confidence interval 4.8–7.3) compared to 6.8% (95% confidence interval 5.1–9.1) after 2000 (P = .44).
When informing patients or comparing outcomes across hospitals, postoperative mortality rates after liver resection should be reported for 90-days with consideration of the diagnosis and the extent of liver resection.
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.
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.
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.
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
Surgical resection for perihilar cholangiocarcinoma (pCCA) is associated with high operative risks. Impaired liver regeneration in patients with pre-existing liver disease may contribute ...to posthepatectomy liver failure (PHLF) and postoperative mortality. This study aimed to determine the incidence of hepatic steatosis and fibrosis and their association with PHLF and 90-day postoperative mortality in pCCA patients.
Methods
Patients who underwent a major liver resection for pCCA were included in the study between 2000 and 2021 from three tertiary referral hospitals. Histopathologic assessment of hepatic steatosis and fibrosis was performed. The primary outcomes were PHLF and 90-day mortality.
Results
Of the 401 included patients, steatosis was absent in 334 patients (83.3%), mild in 58 patients (14.5%) and moderate to severe in 9 patients (2.2%). There was no fibrosis in 92 patients (23.1%), periportal fibrosis in 150 patients (37.6%), septal fibrosis in 123 patients (30.8%), and biliary cirrhosis in 34 patients (8.5%). Steatosis (≥ 5%) was not associated with PHLF (odds ratio OR 1.36; 95% confidence interval CI 0.69–2.68) or 90-day mortality (OR 1.22; 95% CI 0.62–2.39). Neither was fibrosis (i.e., periportal, septal, or biliary cirrhosis) associated with PHLF (OR 0.76; 95% CI 0.41–1.41) or 90-day mortality (OR 0.60; 95% CI 0.33–1.06). The independent risk factors for PHLF were preoperative cholangitis (OR 2.38; 95% CI 1. 36–4.17) and future liver remnant smaller than 40% (OR 2.40; 95% CI 1.31–4.38). The independent risk factors for 90-day mortality were age of 65 years or older (OR 2.40; 95% CI 1.36–4.23) and preoperative cholangitis (OR 2.25; 95% CI 1.30–3.87).
Conclusion
In this study, no association could be demonstrated between hepatic steatosis or fibrosis and postoperative outcomes after resection of pCCA.
Complete resection of perihilar cholangiocarcinoma (pCCA) is the only potentially curative treatment. Long-term survival data is rare and prognostic analyses are hindered by the rarity of the ...disease. This study aimed to determine the cure rate and to identify clinicopathological factors that may preclude cure. All consecutive resections for pathologically confirmed pCCA between 2000 and 2009 in 22 centers worldwide were included in a retrospective cohort study. Each center included its retrospective data series. A total of 460 patients were included with a median follow-up of 10 years for patients alive at last follow-up. Median overall survival (OS) was 29.9 months and 10-year OS was 12.8%. Twenty-nine (6%) patients reached 10-year OS. The observed cure rate was 5%. Factors that virtually precluded cure (i.e., below 1%) according to the mixture cure model included age above 70, Bismuth-Corlette type IV tumors, hepatic artery reconstruction, and positive resection margins. Cure was unlikely (i.e., below 3%) in patients with positive lymph nodes or poor tumor differentiation. These factors need to be considered in patient counseling and long-term follow-up after surgery.
Most data on the treatment and outcomes of intrahepatic cholangiocarcinoma (iCCA) derives from expert centers. This study aimed to investigate the treatment and outcomes of all patients diagnosed ...with iCCA in a nationwide cohort.
Data on all patients diagnosed with iCCA between 2010 and 2018 were obtained from the Netherlands Cancer Registry.
In total, 1747 patients diagnosed with iCCA were included. Resection was performed in 292 patients (17%), 548 patients (31%) underwent palliative systemic treatment, and 867 patients (50%) best supportive care (BSC). The OS median and 1-, and 3-year OS were after resection: 37.5 months (31.0–44.0), 79.2%, and 51.6%,; with systemic therapy, 10.0 months (9.2–10.8), 38.4%, and 5.1%, and with BSC 2.2 months (2.0–2.5), 10.4%, and 1.3% respectively. The resection rate for patients who first presented in academic centers was 33% (96/292) compared to 13% (195/1454) in non-academic centers (P < 0.001).
Half of almost 1750 patients with iCCA over an 8 year period did not receive any treatment with a 1-year OS of 10.4%. Three-year survival was about 50% after resection, while long-term survival was rare after palliative treatment. The resection rate was higher in academic centers compared to non-academic centers.
