Core Tip	Preoperative Hounsfield unit average calculation, determined from psoas muscle area and density, may predict time to adjuvant chemotherapy (AC), AC-related toxicity and completion of AC following pancreaticoduodenectomy for periampullary cancers. However, its ability to predict survival should be evaluated by future research. This study aims to evaluate ability of Hounsfield unit average calculation and psoas muscle index in predicting AC-related and survival outcomes following pancreaticoduodenectomy for periampullary malignancy.
