The Impact of Neutrophil-to-Lymphocyte Ratio and Platelet-to-Lymphocyte Ratio Among Patients with Intrahepatic Cholangiocarcinoma

BACKGROUND: Neutrophil-to-lymphocyte ratio and platelets-to-lymphocyte ratio may be host factors associated with prognosis. We sought to determine whether neutrophil-to-lymphocyte and platelets-to-lymphocyte ratio were associated with overall survival among patients undergoing surgery for intrahepatic cholangiocarcinoma. METHODS: Patients who underwent resection for intrahepatic cholangiocarcinoma between 1990 and 2015 were identified from 12 major centers. Clinicopathologic factors and overall survival were compared among patients stratified by neutrophil-to-lymphocyte ratio and platelets-to-lymphocyte ratio. Risk factors identified on multivariable analysis were included in a prognostic model and the discrimination was assessed using Harrell's concordance index (C index). RESULTS: A total of 991 patients were identified. Median neutrophil-to-lymphocyte ratio and platelets-to-lymphocyte ratio were 2.7 (interquartile range [IQR]: 2.0-4.0) and 109.6 (IQR: 72.4-158.8), respectively. Preoperative neutrophil-to-lymphocyte ratio was elevated (≥5) in 100 patients (10.0%) and preoperative platelets-to-lymphocyte ratio (≥190) in 94 patients (15.2%). Patients with low and high neutrophil-to-lymphocyte ratio and platelets-to-lymphocyte ratio generally had similar baseline characteristics with regard to tumor characteristics. Overall survival was 37.7 months (95% confidence interval [CI]: 32.7-42.6); 1-, 3-, and 5-year overall survival was 78.8%, 51.6%, and 39.3%, respectively. Patients with an neutrophil-to-lymphocyte ratio .05). On multivariable analysis, an elevated neutrophil-to-lymphocyte ratio was independently associated with decreased overall survival (hazard ratio: 1.04, 95% CI: 1.01-1.07; P = .002). Patients could be stratified into low- versus high-risk groups based on standard tumor-specific factors such as lymph node status, tumor size, number, and vascular invasion (C index 0.62). When neutrophil-to-lymphocyte ratio was added to the prognostic model, the discriminatory ability of the model improved (C index 0.71). CONCLUSION: Elevated neutrophil-to-lymphocyte ratio was independently associated with worse overall survival and improved the prognostic estimation of long-term survival among patients with intrahepatic cholangiocarcinoma undergoing resection.info:eu-repo/semantics/publishedVersio

Clinical outcomes of DCD type V liver transplantation: donation after euthanasia

Introduction: Due to shortage of donor organs, physicians and surgeons are forced to accept livers from donation after circulatory death (DCD) donors. One special group of DCD organs are those obtained after euthanasia (DCD type V). To create more awareness on the possibility of organ donation after euthanasia, it is important to evaluate the results of transplantation with this type of graft. The aim of our study was to evaluate the outcome of DCD type V liver transplantation (LT) in the Netherlands and Belgium. Methods: All DCD type V LT performed until 2018 in all three Dutch LT centers and four out of six Belgian LT centers, were included in this study. Grafts that have been preserved with machine perfusion were excluded. Continuous data are expressed as median (IQR), categorical data as number (percentage). Results: Until 2018, 44 DCD type V LT have been performed. Five cases in which the liver was preserved by machine perfusion were excluded. Median age of donor and recipient was 51 years (42–58) and 56 years (48–64), respectively. A neurological disease was the most common underlying disease in donors requesting euthanasia, followed by psychiatric disorders. Median time between administration of the euthanatics and cold perfusion was 19 min (14–25). Peak AST and ALT levels in the recipients were 904 U/l (586–2,478) and 709 U/l (448– 1,841) respectively. One-, three- and five-year patient survival was 90%, 83% and 83%, respectively (figure 1). Five patients (13%) required a retransplantation, due to PNF (n = 1), HAT (n = 1) or post-transplant cholangiopathy (n = 3), the majority within the first year after the prior LT. Conclusion: Liver transplantations with grafts from donors who underwent euthanasia yield satisfying results during the relatively short follow up period that is currently available. Comparison of these results with DCD type III LT and donation after brain death (DBD) LT is currently ongoing

The Effect of Preoperative Chemotherapy Treatment in Surgically Treated Intrahepatic Cholangiocarcinoma Patients-A Multi-Institutional Analysis

INTRODUCTION: While preoperative chemotherapy (pCT) is utilized in many intra-abdominal cancers, the use of pCT among patients with intrahepatic cholangiocarcinoma (ICC) remains ill defined. As such, the objective of the current study was to examine the impact of pCT among patients undergoing curative-intent resection for ICC. METHODS: Patients who underwent hepatectomy for ICC were identified from a multi-institutional international cohort. The association between pCT with peri-operative and long-term clinical outcomes was assessed. RESULTS: Of the 1 057 patients who were identified and met the inclusion criteria, 62 patients (5.9%) received pCT. These patients were noticed to have more advanced disease. Median OS (pCT:46.9 months vs no pCT:37.4 months; P = 0.900) and DFS (pCT: 34.1 months vs no pCT: 29.1 months; P = 0.909) were similar between the two groups. In a subgroup analysis of propensity-score matched patients, there was longer OS (pCT:46.9 months vs no pCT:29.4 months) and DFS (pCT:34.1 months vs no pCT:14.0 months); however this did not reach statistical significance (both P > 0.05). CONCLUSION: In conclusion, pCT utilization among patients with ICC was higher among patients with more advanced disease. Short-term post-operative outcomes were not affected by pCT use and receipt of pCT resulted in equivalent OS and DFS following curative-intent resection.info:eu-repo/semantics/publishedVersio
