BACKGROUND: Determining prognosis in advanced cancer is of key importance. Various prognostic scores have been developed. However, they are often very complex. In this study, we evaluated the feasibility of neutrophil/lymphocyte ratio (NLR) as an index to estimate survival in terminal cancer patients. METHODS: NLR was calculated retrospectively based on blood tests performed at 3 months, 2 months, 4 weeks, 3 weeks, 2 weeks, 1 week, and within 3 days before death in 160 cancer patients (82 men, 78 women; age range, 33-99 years; mean age, 69.8 years). RESULTS: NLR increased significantly with time (P 9.21. The sensitivity, specificity, positive predictive value, and negative predictive value were 65.6, 84.1, 90.6, and 51.1%, respectively. The positive and negative likelihood ratios were 4.125 and 0.409, respectively. CONCLUSIONS: NLR appears to be a useful and simple parameter to predict the clinical outcomes of patients with terminal cancer.
