The relationship between platelet–lymphocyte ratio, neutrophil–lymphocyte ratio, and survival in metastatic gastric cancer on firstline modified docetaxel and cisplatinum plus 5 Fluorourasil Regimen: A single institute experience

Abstract

Background/Aims: The association between platelet–lymphocyte ratio (PLR), neutrophil–lymphocyte ratio (NLR), and survival with response rates were evaluated in metastatic gastric cancer (MGC). Patients and Methods: MGC patients on firstline modified docetaxel/cisplatinum/5-fluorourasil [mDCF; docetaxel 60 mg/m2 (days 1–5), cisplatin 60 mg/m2 (day 1), 5FU 600 mg/m2 (days 1–5), q3w] were evaluated retrospectively. The cutoff values were 160 for PLR and 2.5 for NLR. Progression-free survival (PFS) and overall survival (OS) were estimated for group I (PLR >160), group II (PLR ≤ 160), group III (NLR ≥ 2.5), group IV (NLR 160 and NLR ≥ 2.5), group VI (PLR ≤ 160 and NLR 160 and NLR 160 and/or NLR ≥ 2.5 had significantly shorter PFS and OS (P = 0.04, 0.01, 0.019, and P = 0.003, 0.002, 0.000, respectively). Conclusion: High PLR (> 160) and/or NLR (≥ 2.5) seem to be poor prognostic factors in MGC
