Abstract
Background18 F-FDG is a glucose analogue whose metabolic index SUV can effectively reflect the metabolic level of tumor microenvironment. Aspirin can affect the uptake of 18F-FDG by cancer cells, reducing the SUVmax value of primary tumors, exerting antitumor effect. This study aimed to evaluate the prognostic value of long-term aspirin and the relationship between aspirin intake and PET parameters value of primary tumor in non-small cell lung cancer (NSCLC).MethodsEighty-one NSCLC patients were recruited and divided into two groups: aspirin medication group and control group, who underwent surgery and had pathological diagnosis data between January 2012 and December 2016. Clinical characteristics were retrospective analyzed to evaluate the possibility of clinical prognosis, respectively. Kaplan-Meier curves and a Cox proportional hazard model were applied to evaluate the predictors of prognosis.ResultsThe PET/CT SUVmax of the primary tumor in the aspirin group was lower than that in the control group (P < 0.05). Compared with the control group, the SUVmax, SUVmean and TLG of the primary tumor in aspirin group were lower, but the MTV value had no significant difference. Cox regression analysis showed that N stage and TNM stage were predictors of the prognosis. There was a significant difference in the use of aspirin in NSCLC patients.ConclusionAspirin can reduce SUVmax, SUVmean and TLG in primary tumor and aspirin can improve the prognosis of patients with NSCLC.

18 18 F-deoxyglucose (F-FDG) is a glucose analogue whose metabolic index SUV can effectively reflect the metabolic level of tumor microenvironment
The aim of this study is to investigate the prognostic value of long-term aspirin and the relationship between aspirin intake and Maximum standardized uptake value (SUVmax) value of primary tumor on positron emission tomography/computed tomography (PET/CT) SUVmax in primary non-small cell lung cancer (NSCLC), and to provide a reference for further development of treatment strategies and prognosis
The results showed that N stage, TNM stage, aspirin history, SUVmax value, Mean standardized uptake value (SUVmean) and total glycolysis (TLG) were related to the prognosis of patients (P < 0.05)

Chen et al BMC Cancer (2020) 20:510 maximum standardized uptake value (SUVmax) can effectively reflect the metabolic level of tumor microenvironment. Previous studies have shown that long-term use of aspirin can reduce the SUVmax of primary colorectal cancer. The aim of this study is to investigate the prognostic value of long-term aspirin and the relationship between aspirin intake and SUVmax value of primary tumor on PET/CT SUVmax in primary non-small cell lung cancer (NSCLC), and to provide a reference for further development of treatment strategies and prognosis
