    Publication . Lima, H; Endo, Y; Moazzam, Z; Alaimo, L; Shaikh, C; Munir, M; Resende, V; Guglielmi, A; Pinto Marques, H; Cauchy, F; Lam, V; Poultsides, G; Popescu, I; Alexandrescu, S; Martel, G; Endo, I; Kitago, M; Shen, F; Pawlik, T
    Background: Heterogeneity in hepatocellular carcinoma (HCC) still exists within the Barcelona clinic liver cancer (BCLC) subcategories. We developed a simple model to better discriminate and predict prognosis following resection. Methods: Patients who underwent curative-intent resection for HCC were identified from a multi-institutional database. Predictive factors of survival were identified to develop TAC (tumor burden score [TBS], alpha-fetoprotein [AFP], Child-Pugh CP]) score. Results: Among 1435 patients, median TBS was 5.1 (interquartile range [IQR]: 3.2-8.1), median AFP was 18.3 ng/ml (IQR 4.0-362.5), and 1391 (96.9%) patients were classified as CP-A. Factors associated with overall survival (OS) included TBS (low: referent; medium: HR 2.26, 95% CI: 1.73-2.96; high: HR = 3.35, 95% CI: 2.22-5.07), AFP (<400 ng/ml: referent; >400 ng/ml: HR = 1.56, 95% CI: 1.27-1.92), and CP (A: referent; B: HR = 1.81, 95% CI: 1.12-2.92) (all p < 0.05). A simplified risk score demonstrated superior concordance index, Akaike information criteria, homogeneity, and area under the curve versus BCLC (0.620 vs. 0.541; 5484.655 vs. 5536.454; 60.099 vs. 16.194; 0.62 vs. 0.55, respectively), and further stratified patients within BCLC groups relative to OS (BCLC 0, very low: 86.8%, low: 47.8%) (BCLC A, very low: 79.7%, low: 68.1%, medium: 52.5%, high: 35.6%) (BCLC B, low: 59.8%, medium: 43.7%, high: N/A). Conclusion: TAC is a simple, holistic score that consistently outperformed BCLC relative to discrimination power and prognostication following resection of HCC.

  • Preoperative Risk Score (PreopScore) to Predict Overall Survival After Resection for Hepatocellular Carcinoma.
    Publication . Endo, Yutaka; Lima, Henrique A; Alaimo, Laura; Moazzam, Zorays; Brown, Zachary; Shaikh, Chanza F; Ratti, Francesca; Pinto Marques, Hugo; Soubrane, Olivier; Lam, Vincent; Poultsides, George A; Popescu, Irinel; Alexandrescu, Sorin; Martel, Guillaume; Workneh, Aklile; Guglielmi, Alfredo; Hugh, Tom; Aldrighetti, Luca; Shen, Feng; Endo, Itaru; Pawlik, Timothy M; Elsevier
    Background: This study aimed to develop a holistic risk score incorporating preoperative tumor, liver, nutritional, and inflammatory markers to predict overall survival (OS) after hepatectomy for hepatocellular carcinoma (HCC). Methods: Patients who underwent curative-intent surgery for HCC between 2000 and 2020 were identified using an international multi-institutional database. Preoperative predictors associated with OS were selected and a prognostic risk score model (PreopScore) was developed and validated using cross-validation. Results: A total of 1676 patients were included. On multivariable analysis, preoperative parameters associated with OS included α-feto protein (hazard ratio [HR]1.17, 95%CI 1.03-1.34), neutrophil-to-lymphocyte ratio (HR2.62, 95%CI 1.30-5.30), albumin (HR0.49, 95%CI 0.34-0.70), gamma-glutamyl transpeptidase (HR1.00, 95%CI 1.00-1.00), as well as vascular involvement (HR3.52, 95%CI 2.10-5.89) and tumor burden score (medium, HR3.49, 95%CI 1.62-7.58; high, HR3.21, 95%CI 1.40-7.35) on preoperative imaging. A weighted PreopScore was devised and made available online (https://yutaka-endo.shinyapps.io/PrepoScore_Shiny/). Patients with a PreopScore 0-2, 2-3.5, and >3.5 had incrementally worse 5-year OS of 85.8%, 70.7%, and 52.4%, respectively (p < 0.001). The c-index of the test and validation cohort were 0.75 and 0.71, respectively. The PreopScore outperformed individual parameters and previous HCC staging systems. Discussion: The PreopScore can be used as a better guide to preoperatively identify patients and individualize pre-/post-operative strategies.

  • Albumin-Bilirubin Grade and Tumor Burden Score Predict Outcomes Among Patients with Intrahepatic Cholangiocarcinoma After Hepatic Resection: a Multi-Institutional Analysis.
    Publication . Munir, Muhammad Musaab; Endo, Yutaka; Lima, Henrique A; Alaimo, Laura; Moazzam, Zorays; Shaikh, Chanza; Poultsides, George A; Guglielmi, Alfredo; Aldrighetti, Luca; Weiss, Matthew; Bauer, Todd W; Alexandrescu, Sorin; Kitago, Minoru; Maithel, Shishir K; Pinto Marques, Hugo; Martel, Guillaume; Pulitano, Carlo; Shen, Feng; Cauchy, François; Koerkamp, Bas Groot; Endo, Itaru; Pawlik, Timothy M; Springer
    Background: The prognostic role of tumor burden score (TBS) relative to albumin-bilirubin (ALBI) grade among patients undergoing curative-intent resection of ICC has not been examined. Methods: We identified patients who underwent curative-intent resection for ICC between 1990 and 2017 from a multi-institutional database. Multivariable analysis was performed to assess the effect of TBS relative to ALBI grade on both short- and long-term outcomes. Results: Among 724 patients, 360 (49.7%) patients had low TBS and low ALBI grade, 142 (19.6%) patients had low TBS and high ALBI grade, 138 (19.1%) patients had high TBS and low ALBI grade, and 84 patients (11.6%) had high TBS and high ALBI grade. Decreased tumor burden was associated with better long-term outcomes among patients with both low (5-year OS; low TBS vs. high TBS: 52.4% vs 21.4%; p < 0.001) and high ALBI grade (5-year OS; low TBS vs. high TBS: 40.7% vs 12.0%; p < 0.001). On multivariable analysis, higher ALBI grade was associated with greater odds of an extended hospital LOS (> 10 days) (OR 2.80, 95%CI 1.62-4.82; p < 0.001), perioperative transfusion (OR 2.04, 95%CI 1.25-3.36; p = 0.005), 90-day mortality (OR 2.56, 95%CI 1.12-5.81; p = 0.025), as well as a major complication (OR 1.99, 95%CI 1.13-3.49; p = 0.016) among patients with similar tumor burden. Of note, patients with high TBS and high ALBI grade had markedly worse overall survival compared with patients who had low TBS and low ALBI grade disease (HR 2.27; 95%CI 1.44-3.59; p < 0.001). Importantly, high TBS and high ALBI grade were strongly associated with both early recurrence (88.1%%) and 5-year risk of death (96.4%). Conclusion: Both TBS (i.e., tumor morphology) and ALBI grade (i.e., hepatic function reserve) were strong predictors of outcomes among patients undergoing ICC resection. There was an interplay between TBS and ALBI grade relative to patient prognosis after hepatic resection of ICC with high ALBI grade predicting worse outcomes among ICC patients with different TBS.
