Lymph node yield ≥4 is associated with improved overall and cancer-specific survival after resection of cholangiocarcinoma: a population-based SEER analysis, 2004-2015.
INTRODUCTION Regional lymphadenectomy is standard in curative-intent resection of cholangiocarcinoma (CCA), but the optimal lymph node yield remains uncertain. We assessed the association between lymph node yield and overall (OS) and cancer-specific (CSS) survival. MATERIALS AND METHODS Patients with histologically c...
