Background Several studies have shown that the neutrophil to lymphocyte ratio (NLR) in peripheral blood is a prognostic factor of various cancers. However, there is limited information on the clinical and prognostic significance of NLR in patients with metastatic advanced gastric cancer (AGC). Therefore, we examined whether the NLR can be used as a prognostic marker for predicting chemotherapeutic response and survival outcomes in metastatic AGC patients who are receiving palliative chemotherapy. Method A total of 268 patients diagnosed with metastatic AGC were enrolled. NLR was calculated from complete blood cell count taken before the first chemotherapy treatment. Patients were divided into two groups according to the median value of NLR: a high NLR group and a low NLR group. Result The median follow-up period was 340 days (range 72-1796 days) and median NLR was 3.06 (range 0.18-18.16). The high NLR group (NLR [3.0) contained 138 patients and the low NLR group (NLR B3.0) contained 130 patients. Low NLR group patients had a significantly higher chemotherapeutic disease control rate (90.0 % vs. 80.4; P = 0.028), and longer progression-free survival (PFS) and overall survival (OS) than the high NLR group patients (186 vs. 146 days; P = 0.001; 414 vs. 280 days; P \ 0.001, respectively). In multivariate analysis, NLR showed a significant association with PFS (HR 1.478; 95 % CI 1.154-1.892; P = 0.002) and OS (HR 1.569; 95 % CI 1.227-2.006; P \ 0.001). Conclusion Pretreatment NLR is a useful prognostic marker in patients with metastatic AGC who are undergoing palliative chemotherapy.

Background and AimsDiagnostic values of FibroTest (FT) for hepatic fibrosis have rarely been assessed in Asian chronic hepatitis B (CHB) patients. We aimed to validate its diagnostic performances in comparison with liver stiffness (LS).MethodsFrom 2008 to 2010, 194 CHB patients who underwent liver biopsies along with FT and transient elastography were prospectively enrolled. Fibrosis stage was assessed according to the Batts and Ludwig system.ResultsTo predict significant fibrosis (F≥2), advanced fibrosis (F≥3), and cirrhosis (F = 4), areas under receiver operating characteristic curves (AUROCs) of FT were 0.903, 0.907, and 0.866, comparable to those of LS (0.873, 0.897, and 0.910, respectively). Optimized cutoffs of FT to maximize sum of sensitivity and specificity were 0.32, 0.52, and 0.68 for F≥2, F≥3, and F = 4, while those of LS were 8.8, 10.2, and 14.1 kPa, respectively. According to FT and LS cutoffs, 123 (63.4%) and 124 (63.9%) patients were correctly classified consistent with histological fibrosis (F1, F2, F3, and F4), respectively. Overall concordance between each fibrosis stage estimated by FT and LS was observed in 111 patients, where 88 were correctly classified with histological results. A combination formula adding LS to FT (LS+FT) showed similar AUROC levels (0.885, 0.905, and 0.915), while another multiplying LS by FT (LS×FT) showed the best AUROCs (0.941, 0.931, and 0.929 for F≥2, F≥3, and F4, respectively).ConclusionsFT provides good fibrosis prediction, with comparable outcomes to LS in Asian CHB patients. FT substantially reduces need for liver biopsy, especially when used in combination with LS.
