Although rare, intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignancy and the incidence of ICC has increased 14% per year in recent decades. Treatment of ICC remains difficult as most people present with advanced disease not amenable to curative-intent surgical resection. Even among patients with operable disease, margin-negative surgical resection can be difficult to achieve and the incidence of recurrence remains high. As such, there has been considerable interest in systemic chemotherapy and targeted therapy for ICC. Over the last decade, the understanding of the molecular and genetic foundations of ICC has reshaped treatment approaches and strategies. Next-generation sequencing has revealed that most ICC tumors have at least one targetable mutation. These advancements have led to multiple clinical trials to examine the safety and efficacy of novel therapeutics that target tumor-specific molecular and genetic aberrations. While these advancements have demonstrated survival benefit in early phase clinical trials, continued investigation in randomized larger-scale trials is needed to further define the potential clinical impact of such therapy.
Background and objectives: Composite measures are increasingly used to assess quality of care in surgical oncology. We sought to define the incidence of "textbook oncologic outcome" (TOO) following resection of gastric adenocarcinoma among a large, international cohort of patients.Methods: Gastric adenocarcinoma patients undergoing resection between 2000 and 2020 were identified from an international database. TOO was defined as marginnegative resection, examination of ≥16 lymph nodes, no prolonged length-of-stay (LOS), no 30-day mortality, and stage-appropriate receipt of chemotherapy.Results: Among a total of 910 patients, 321 patients (35.3%) achieved a postoperative TOO. While failure to evaluate ≥16 lymph nodes (n = 591, 65.0%) and receipt of chemotherapy (n = 651, 71.5%) had the greatest negative impact on the ability to obtain a TOO, no 30-day mortality (n = 880, 96.7%), margin-negative resection (n = 831, 91.3%), and no extended LOS (n = 706, 77.6%) were more commonly achieved. No postoperative complications (OR: 0.44; 95% CI: 0.31−0.63) and T1a/T1b-stage disease (OR: 2.87; 95% CI: 1.59−5.18) were independently associated with achieving a TOO (p < 0.05). The odds of achieving a TOO improved over time (p-trend < 0.05), which was largely attributable to improved odds of evaluat-
