The role of overall tumor burden (TB) in intrahepatic cholangiocarcinoma (ICC) remains poorly defined. In our recently published article (https://doi.org/10.1245/s10434-020-09393-7), we demonstrated that TB dictated prognosis among patients with resectable ICC. In particular, TB was independently associated with both overall survival (medium-TB: HR = 1.40, 95% confidence interval [CI] 1.14–1.71; high-TB: HR = 1.89, 95% CI 1.46–2.45) and disease-free survival (medium-TBS, HR = 1.61, 95% CI 1.33–1.96; high-TB: HR = 2.03, 95% CI 1.56–2.64) following ICC resection. Adjuvant chemotherapy was associated with a greater survival among patients with high TB. TB may be used as a tool to help guide post-resection treatment strategies.
