Hematological parameters in EGFR-mutated advanced NSCLC patients treated with TKIs: predicting survival and toxicity.
2021
Background: The aim of this study was to analyze the prognostic value of pre-treatment hematological parameters in EGFR-mutated non-small cell lung cancer patients treated with tyrosine-kinase inhibitors (TKIs).Patients and methods: Patients with EGFR mutations were treated with EGFR-TKIs in the first line until progression/unacceptable toxicity. Hematological parameters were derived from the absolute baseline differential counts of a complete blood count. The associations between the patients' and tumor characteristics were analyzed using Pearson Chi-Square, Fisher's exact, t-test, and Mann-Whitney tests. Cutoff values were determined using ROC curves, and correlation with survival was examined by Kaplan-Meier method and Cox regression.Results: Patients with NMR 2.9 and LMR 190 more often had paronichia, diarrhea and hyperbilirubinemia.Conclusion: Low baseline value of the hematological parameter NMR has shown potential as a routine, low-cost, and minimally invasive predictor of survival in EGFR-TKI-treated NSCLC patients.
