Preoperative neutrophili-to-lymphocyte ratio is useful for stratifying the prognosis of tumor markers-negative pancreatic cancer patients.
American Journal of Surgery 2019 April 22
BACKGROUND: Elevated levels of preoperative tumor markers (TMs), including carcinoembryonic antigen and carbohydrate antigen 19-9 are risk factors for the survival of patients with pancreatic cancer (PC). However, TMs are not always applicable in various conditions. This study aimed to investigate the prognostic value of systemic inflammatory marker (SIM) in such patients.
METHODS: Seventy-seven patients who underwent curative surgery for PC with negative TMs were included in this study. Various SIMs for each patient were examined to determine the most reliable one. Using the most superior SIM, the patients were divided into two groups and their characteristics and postoperative results were compared.
RESULTS: The NLR was superior to other SIMs. Despite no significant intergroup differences were observed between the groups, the overall survival (OS) rate was significantly higher in the low NLR group than in the high NLR group (5-year OS rate: 81.2% vs. 24.2%, p < 0.001).
CONCLUSION: The NLR is a simple and reliable prognostic marker in TM-negative PC patients.
