Core Tip

Core Tip: In light of emerging evidence that has substantiated the correlation between malnutrition and immune suppression with poor prognosis across various cancer types, we examined the prognostic significance of the preoperative prognostic nutritional index (PNI) in patients with ampullary adenocarcinoma (AC) who underwent curative pancreaticoduodenectomy (PD). Our findings revealed that the PNI, pathological T stage and pathological N stage were independent prognostic factors for both overall survival and disease-free survival in AC patients who underwent curative PD.
