Abstract
Introduction: Lung cancer is the leading cause of cancer-related deaths, worldwide. Despite immune checkpoint inhibitors and targeted therapy have revolutionized the treatment of metastatic nonsmall cell lung cancer (NSCLC), a significant proportion of patients are still treated with platinum-based chemotherapy. It is widely noticed that systemic inflammation plays an important role in the development and progression of many solid tumors. In this study, we aimed to analyze the predictive role of the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), and prognostic nutritional index (PNI) in patients with advanced NSCLC treated with first-line platinum-doublet chemotherapy. Methods: We retrospectively collected data of patients treated with first-line therapy for metastatic NSCLC. All patients were treated with first-line platinum-doublet chemotherapy. The patients were grouped based on the median values of SII, PNI, and NLR. The Mann-Whitney U test was used for comparisons between groups. Results: The chemotherapy response rate (RR) was 75% in all patients. RR is statistically significantly lower in high SII, low PNI, and high NLR groups. Conclusions: High inflammatory indexes in metastatic NSCLC patients who were treated with platinum-doublet chemotherapy are related to low chemotherapy RR.
