- 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; SpringerBackground: 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.
- Should Utilization of Lymphadenectomy Vary According to Morphologic Subtype of Intrahepatic Cholangiocarcinoma?Publication . Zhang, Xu-Feng; Lv, Yi; Weiss, Matthew; Popescu, Irinel; Pinto Marques, Hugo; Aldrighetti, Luca; Maithel, Shishir K; Pulitano, Carlo; Bauer, Todd W; Shen, Feng; Poultsides, George A; Soubrane, Oliver; Martel, Guillaume; Koerkamp, B Groot; Itaru, Endo; Pawlik, Timothy MObjective: We sought to evaluate the utilization of lymphadenectomy (LND) and the incidence of lymph node metastasis (LNM) among different morphologic types of intrahepatic cholangiocarcinoma (ICC). Methods: Clinical data of patients undergoing curative-intent resection for ICC between 1990 and 2017 were collected and analyzed. The preoperative nodal status was evaluated by imaging studies, and the morphologic and lymph node (LN) status was collected on final pathology report. Results: Overall, 1032 patients had a mass-forming (MF) or intraductal growth (IG) ICC subtype, whereas 150 patients had a periductal infiltrating (PI) or MF + PI subtype. Among the 924 patients with MF/IG ICC subtype who had nodal assessment on preoperative imaging, 747 (80.8%) were node-negative, whereas 177 (19.2%) patients were suspicious for metastatic nodal disease. On final pathological analysis, 71 of 282 (25.2%) patients who had preoperative node-negative disease ultimately had LNM. In contrast, 79 of 135 (58.5%) patients with preoperative suspicious/metastatic LNs had pathologically confirmed LNM (odds ratio [OR] 4.2, p < 0.001). Among the 129 patients with PI/MF + PI ICC subtype and preoperative nodal information, 72 (55.8%) were node-negative on preoperative imaging. In contrast, 57 (44.2%) patients had suspicious/metastatic LNs. On final pathologic examination, 45.3% (n = 24) of patients believed to be node-negative on preoperative imaging had LNM; 68.0% (n = 34) of patients who had suspicious/positive nodal disease on imaging ultimately had LNM (OR 2.6, p = 0.009). Conclusion: Given the low accuracy of preoperative imaging evaluation of nodal status, routine LND should be performed at the time of resection for both MF/IG and PI/MF + PI ICC subtypes.
