Classification of Intrahepatic Cholangiocarcinoma into Perihilar Versus Periphe...
Wei, T; Lu, J; Xiao, XL; Weiss, M; Popescu, I; Pinto Marques, H; Aldrighetti, L; Maithel, SK; Pulitano, C; Bauer, TW; Shen, F; Poultsides, GABackground: Intrahepatic cholangiocarcinoma (ICC) constitutes a group of heterogeneous malignancies within the liver. We sought to subtype ICC based on anatomical origin of tumors, as well as propose modifications of the current classification system. Methods: Patients undergoing curative-intent resection for ICC, hilar cholangiocarcinoma (CCA), or hepatocellular carcinoma (HCC) were identified from three inter...
Tumor Necrosis Impacts Prognosis of Patients Undergoing Resection for T1 Intrah...
Tsilimigras, DI; Ejaz, A; Cloyd, J; Guglielmi, A; Aldrighetti, L; Weiss, M; Bauer, TW; Alexandrescu, S; Poultsides, GA; Maithel, SK; Pinto Marques, HBackground: The prognostic impact of tumor necrosis among patients undergoing resection for intrahepatic cholangiocarcinoma (ICC) remains ill-defined. Methods: Patients who underwent curative-intent resection for ICC between 2000 and 2017 were identified using a multi-institutional database. The association of pathologic tumor necrosis with overall survival (OS) and recurrence-free survival (RFS) was examined. ...
Proposed modification of the Eighth Edition of the AJCC Staging System for Intr...
Zhang, XF; Xue, F; He, J; Alexandrescu, S; Marques, HP; Aldrighetti, L; Maithel, SK; Pulitano, C; Bauer, TW; Shen, F; Poultsides, GA; Soubrane, OBackground: To improve the prognostic accuracy of the 8th edition of the American Joint Committee on Cancer (AJCC) staging system for intrahepatic cholangiocarcinoma (ICC) with establishment and validation of a modified TNM (mTNM) staging system. Methods: Data on patients who underwent curative-intent resection for ICC was collected from 15 high-volume centers worldwide (n = 643). An external validation dataset...
Tumor Burden Dictates Prognosis Among Patients Undergoing Resection of Intrahep...
Tsilimigras, DI; Hyer, JM; Paredes, AZ; Moris, D; Sahara, K; Guglielmi, A; Aldrighetti, L; Weiss, M; Bauer, TW; Alexandrescu, S; Poultsides, GAIntroduction: While tumor burden (TB) has been associated with outcomes among patients with hepatocellular carcinoma, the role of overall TB in intrahepatic cholangiocarcinoma (ICC) remains poorly defined. Methods: Patients undergoing curative-intent resection of ICC between 2000 and 2017 were identified from a multi-institutional database. The impact of TB on overall (OS) and disease-free survival (DFS) was ev...
Predicting Lymph Node Metastasis in Intrahepatic Cholangiocarcinoma
Tsilimigras, DI; Sahara, K; Paredes, AZ; Moro, A; Mehta, R; Moris, D; Guglielmi, A; Aldrighetti, L; Weiss, M; Bauer, TW; Alexandrescu, S; Poultsides, GABackground: The objective of the current study was to develop a model to predict the likelihood of occult lymph node metastasis (LNM) prior to resection of intrahepatic cholangiocarcinoma (ICC). Methods: Patients who underwent hepatectomy for ICC between 2000 and 2017 were identified using a multi-institutional database. A novel model incorporating clinical and preoperative imaging data was developed to predict...
Impact of Microvascular Invasion on Clinical Outcomes After Curative-Intent Res...
Hu, LS; Weiss, M; Popescu, I; Pinto Marques, H; Aldrighetti, L; Maithel, SK; Pulitano, C; Bauer, TW; Shen, F; Poultsides, GA; Soubrane, O; Martel, GBackground: Microvascular invasion (MiVI) is a histological feature of intrahepatic cholangiocarcinoma (ICC) that may be associated with biological behavior. We sought to investigate the impact of MiVI on long-term survival of patients undergoing curative-intent resection for ICC. Methods: A total of 1089 patients undergoing curative-intent resection for ICC were identified. Data on clinicopathological characte...
Impact of Body Mass Index on Tumor Recurrence Among Patients Undergoing Curativ...
Merath, K; Mehta, R; Hyer, JM; Bagante, F; Sahara, K; Alexandrescu, S; Pinto Marques, H; Aldrighetti, Luca; Maithel, SK; Pulitano, C; Weiss, MJBackground: The association between body mass index (BMI) and long-term outcomes of patients with ICC has not been well defined. We sought to define the presentation and oncologic outcomes of patients with ICC undergoing curative-intent resection, according to their BMI category. Methods: Patients who underwent resection of ICC were identified in a multi-institutional database. Patients were categorized as norm...
Early Versus Late Recurrence of Intrahepatic Cholangiocarcinoma After Resection...
Zhang, XF; Beal, EW; Bagante, F; Chakedis, J; Weiss, M; Popescu, I; Pinto Marques, H; Aldrighetti, L; Maithel, SK; Pulitano, C; Bauer, TW; Shen, FBackground: The objective of this study was to investigate the characteristics, treatment and prognosis of early versus late recurrence of intrahepatic cholangiocarcinoma (ICC) after hepatic resection. Methods: Patients who underwent resection with curative intent for ICC were identified from a multi-institutional database. Data on clinicopathological characteristics, initial operative details, timing and sites...
Preoperative Risk Score and Prediction of Long-Term Outcomes after Hepatectomy ...
Sasaki, K; Margonis, GA; Andreatos, N; Bagante, F; Weiss, M; Barbon, C; Popescu, I; Pinto Marques, H; Aldrighetti, L; Maithel, SK; Pulitano, CBackground: Accurate prediction of prognosis for patients with intrahepatic cholangiocarcinoma (ICC) remains a challenge. We sought to define a preoperative risk tool to predict long-term survival after resection of ICC. Study design: Patients who underwent hepatectomy for ICC at 1 of 16 major hepatobiliary centers between 1990 and 2015 were identified. Clinicopathologic data were analyzed and a prognostic mode...
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 ...
