OBJECTIVE: To analyze the prognostic significance of the pretreatment platelet/lymphocyte ratio (PLR) for targeted therapy in patients with epidermal growth factor receptor (EGFR)-mutated non-small-cell lung cancer (NSCLC). METHODS: We conducted a retrospective study of 96 patients with EGFR-mutated advanced NSCLC who were treated at Dongguan People's Hospital, Southern Medical University from May 2014 to December 2017. All patients received EGFR-targeted therapy until disease progression, unacceptable toxicity, or other factors. Approximately 3 days before the initial treatment, data including a detailed clinical history, physical examination, radiographic results, pathological diagnosis, and laboratory parameters including complete blood cell counts and albumin levels were evaluated. RESULTS: Patients in the PLR ≥ 190 group had shorter progression-free survival (PFS) than those in the PLR < 190 group. Furthermore, the 1-year PFS rate was worse in the PLR ≥ 190 group than in the PLR< 190 group. Multivariate analysis indicated the possible role of PLR as a prognostic factor for patients with advanced NSCLC who received EGFR-targeted therapy. CONCLUSIONS: Pretreatment PLR may be an independent prognostic factor for patients with NSCLC receiving EGFR tyrosine kinase inhibitor treatment. Further studies are needed to identify the impact of PLR on EGFR-mutated NSCLC.
