- Defining When to Offer Operative Treatment for Intrahepatic Cholangiocarcinoma: A Regret-Based Decision Curves AnalysisPublication . Bagante, F; Spolverato, G; Cucchetti, A; Gani, F; Popescu, I; Ruzzenente, A; Pinto Marques, H; Aldrighetti, L; Gamblin, T; Maithel, S; Sandroussi, C; Bauer, T; Shen, F; Poultsides, G; Marsh, J; Guglielmi, A; Pawlik, TBACKGROUND: Regret-based decision curve analysis (DCA) is a framework that assesses the medical decision process according to physician attitudes (expected regret) relative to disease-based factors. We sought to apply this methodology to decisions around the operative management of intrahepatic cholangiocarcinoma (ICC). METHODS: Utilizing a multicentric database of 799 patients who underwent liver resection for ICC, we developed a prognostic nomogram. DCA tested 3 strategies: (1) perform an operation on all patients, (2) never perform an operation, and (3) use the nomogram to select patients for an operation. RESULTS: Four preoperative variables were included in the nomogram: major vascular invasion (HR = 1.36), tumor number (multifocal, HR = 1.18), tumor size (>5 cm, HR = 1.45), and suspicious lymph nodes on imaging (HR = 1.47; all P < .05). The regret-DCA was assessed using an online survey of 50 physicians, expert in the treatment of ICC. For a patient with a multifocal ICC, largest lesion measuring >5 cm, one suspicious malignant lymph node, and vascular invasion on imaging, the 1-year predicted survival was 52% according to the nomogram. Based on the therapeutic decision of the regret-DCA, 60% of physicians would advise against an operation for this scenario. Conversely, all physicians recommended an operation to a patient with an early ICC (single nodule measuring 3 cm, no suspicious lymph nodes, and no vascular invasion at imaging). CONCLUSION: By integrating a nomogram based on preoperative variables and a regret-based DCA, we were able to define the elements of how decisions rely on medical knowledge (postoperative survival predicted by a nomogram, severity disease assessment) and physician attitudes (regret of commission and omission).
- A Multi-Institutional Analysis of Elderly Patients Undergoing a Liver Resection for Intrahepatic CholangiocarcinomaPublication . Vitale, A; Spolverato, G; Bagante, F; Gani, F; Popescu, I; Pinto Marques, H; Aldrighetti, L; Gamblin, TC; Maithel, S; Sandroussi, C; Bauer, T; Shen, F; Poultsides, G; Marsh, J; Pawlik, TBACKGROUND: Little is known regarding postoperative outcomes of elderly patients undergoing liver surgery for intrahepatic cholangiocarcinoma (ICC). METHODS: Five hundred and eighty-four patients undergoing liver resection for ICC between 1990 and 2015 were identified. Perioperative morbidity, mortality, overall survival (OS), and disease-free survival (DFS) were compared between elderly (>70 year, n = 129) and non-elderly (≤70 years, n = 455) patients. RESULTS: Older patients had a higher incidence of complications (elderly vs. non-elderly; 52.7% vs. 42.6%; P = 0.03), as well as major complications (elderly vs. non-elderly; 24.0% vs. 14.9%; P = 0.01); 30-day (0.1% vs. 3.3%; P > 0.05), and 90-day mortality (2.3% vs. 5.5%; P > 0.05) were comparable. Five-year OS and DFS were comparable between the elderly and non-elderly patients (OS, 13.3% vs. 24.4%; and DFS; 7.3% vs. 12.0%; P > 0.05). On propensity score matching, DFS and OS were also comparable among non-elderly versus elderly patients. Poor tumor grade was associated with worse DFS among elderly patients (HR = 1.6, 95%CI 1.0-2.6; P = 0.04), whereas periductal invasion (HR = 1.9, 95% CI 1.1-3.5; P = 0.03) and nodal disease (HR = 2.3, 95% CI 1.3-3.9; P = 0.003) were predictive of shorter DFS among non-elderly patients. CONCLUSION: Elderly patients undergoing liver surgery for ICC demonstrated an increased risk of perioperative complications, but comparable long-term DFS and OS compared with younger patients. Rather, tumor characteristics were more predictive of worse long-term outcomes.
