Prognosis and Adherence with the National Comprehensive Cancer Network Guidelines of Patients with Biliary Tract Cancers: an Analysis of the National Cancer Database

Background The National Comprehensive Cancer Network (NCCN) guidelines recommend chemotherapy for patients with inoperable biliary tract cancers (BTC), as well as patients following resection of BTC with lymph node metastasis (N1)/positive margins (R1). We sought to define overall adherence, as well as long-term outcomes, with the NCCN guidelines for BTC using the National Cancer Database (NCDB).
