The Impact of Donor Risk Index, Recipients’ and Operative Characteristics on Po...
Cardoso, FS; Bagulho, L; Coelho, JS; Lamelas, J; Mateus, E; Mendes, M; Glória, H; Ribeiro, V; Mega, R; Pena, A; Pinto Marques, H; Germano, N; Nolasco, FBackground and Aims: The donor risk index (DRI) quantifies donor-related characteristics potentially associated with increased risk of early graft failure. We aimed to assess the impact of the DRI, recipient and perioperative factors on post liver transplant (LT) outcomes. Methods: This was a singlecenter retrospective cohort study including all adult (≥18 years) patients who underwent LT from 01/2019 to 12/201...
Pancreas Rejection in the Artificial Intelligence Era: New Tool for Signal Pati...
Vigia, E; Ramalhete, L; Ribeiro, R; Barros, I; Chumbinho, B; Filipe, E; Pena, A; Bicho, L; Nobre, A; Carrelha, S; Sobral, M; Lamelas, J; Coelho, JSIntroduction: Pancreas transplantation is currently the only treatment that can re-establish normal endocrine pancreatic function. Despite all efforts, pancreas allograft survival and rejection remain major clinical problems. The purpose of this study was to identify features that could signal patients at risk of pancreas allograft rejection. Methods: We collected 74 features from 79 patients who underwent simu...
Predicting Function Delay with a Machine Learning Model: Improve the Long-term ...
Vigia, E; Ramalhete, L; Barros, I; Chumbinho, B; Filipe, E; Pena, A; Bicho, L; Nobre, A; Carrelha, S; Corado, S; Sobral, M; Lamelas, J; Santos Coelho, JThe impact of delayed graft function on outcomes following various solid organ transplants is well documented and addressed in the literature. Delayed graft function following various solid organ transplants is associated with both short- and long-term graft survival issues. In a retrospective cohort study including 106 patients we evaluated whether pancreas graft survival differs according to moment of insulin...
Survival after Resection of Multiple Tumor Foci of Intrahepatic Cholangiocarcinoma
Buettner, S; Ten Cate, D; Bagante, F; Alexandrescu, S; Pinto Marques, H; Lamelas, J; Aldrighetti, L; Gamblin, T; Maithel, S; Pulitano, C; Margonis, GBackground: Multiple tumor foci of intrahepatic cholangiocarcinoma (ICC) are often considered a contra-indication for resection. We sought to define long-term outcomes after resection of ICC in patients with multiple foci. Methods: Patients who underwent resection for ICC between 1990 and 2017 were identified from 12 major HPB centers. Outcomes of patients with solitary lesions, multiple lesions (ML), and oligo...
The Impact of Neutrophil-to-Lymphocyte Ratio and Platelet-to-Lymphocyte Ratio A...
Buettner, S; Spolverato, G; Kimbrough, CW; Alexandrescu, S; Pinto Marques, H; Lamelas, J; Aldrighetti, L; Gamblin, T; Maithel, SK; Pulitano, C; Weiss, MBACKGROUND: 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 ...
The Effect of Preoperative Chemotherapy Treatment in Surgically Treated Intrahe...
Buettner, S; Koerkamp, BG; Ejaz, A; Buisman, FE; Kim, Y; Margonis, GA; Alexandrescu, S; Pinto Marques, H; Lamelas, J; Aldrighetti, L; Gamblin, TCINTRODUCTION: 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-inst...
Performance of Prognostic Scores and Staging Systems in Predicting Long-Term Su...
Buettner, S; Galjart, B; van Vugt, JL; Bagante, F; Alexandrescu, S; Pinto Marques, H; Lamelas, J; Aldrighetti, L; Gamblin, TC; Maithel, SK; Pulitano, CINTRODUCTION: We sought to validate the commonly used prognostic models and staging systems for intrahepatic cholangiocarcinoma (ICC) in a large multi-center patient cohort. METHODS: The overall (OS) and disease free survival (DFS) prognostic discriminatory ability of various commonly used models were assessed in a large retrospective cohort. Harrell's concordance index (c-index) was used to determine accuracy ...
Management and Outcomes of Patients with Recurrent Intrahepatic Cholangiocarcin...
Spolverato, G; Kim, Y; Alexandrescu, S; Pinto Marques, H; Lamelas, J; Aldrighetti, L; Clark Gamblin, T; Maithel, SK; Pulitano, C; Bauer, TW; Shen, FBACKGROUND: Management and outcomes of patients with recurrent intrahepatic cholangiocarcinoma (ICC) following curative-intent surgery are not well documented. We sought to characterize the treatment of patients with recurrent ICC and define therapy-specific outcomes. METHODS: Patients who underwent surgery for ICC from 1990 to 2013 were identified from an international database. Data on clinicopathological cha...
