Abstract
Aim: The study aimed to assess the value of pretreatment peripheral blood neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), pan-immune-inflammation value (PIV) and systemic immune-inflammation index (SII) for predicting immunotherapy prognosis and efficacy in advanced gastric cancer (GC). Methods: A total of 84 advanced GC patients received immunotherapy were retrospectively collected. The optimal cut-off values were determined by receiver operating characteristic curves. The univariate and multivariate analysis investigated the effects of NLR, PLR, PIV and SII on patients prognosis. Results: NLR, PLR, PIV and SII had predictive value of efficacy. NLR ≥3.65 was an independent risk factor for worse outcomes. Conclusion: NLR, PLR, PIV and SII have predictive value of efficacy and NLR ≥3.65 suggests a poor prognosis following immunotherapy in advanced GC.
Plain language summary
Immunotherapy can make gastric cancer patients live longer. However, not all patients live longer. We need simple, inexpensive and effective indicators to find patients who can live longer with immunotherapy. Routine blood test is common in our daily lives. Previous studies reported that some indicators in routine blood test can predict the prognosis and efficacy of surgery in gastric cancer patients. But it is not clear in immunotherapy for advanced gastric cancer patients. In our trial, we found that some indicators in routine blood test can help predict the effect of immunotherapy in patients with advanced gastric cancer and screen which patients will live longer with immunotherapy.
