				        	Objective To explore the value of PLR in peripheral blood in the efficacy and prognosis of targeted therapy for NSCLC with EGFR-mutated. Methods Ninety patients with EGFR-mutant of NSCLC were selected, and the PLR was calculated before targeted therapy. The PLR median was used as a cut-off point for grouping, and they were assigned to group A (low PLR group) and group B (high PLR group). All patients were treated with EGFR-TKIs. Relationship between PLR and clinicopathological features was analyzed. Objective efficacy, ORR, DCR, PFS and OS between the two groups were compared. Results Before EGFR-TKIs therapy, median PLR was 139, and there were 44 patients in group A, and 46 in group B. There were statistical differences regarding smoking, tumor location, histological differentiation, T staging, and clinical staging between group A and B (P <0.05). The rates of PR, ORR and DCR in group A were higher than those in group B, and the PD rate was lower than that in group B (P < 0.05). Log-rank test showed that median OS and median PFS in group A were longer than those in group B (P= 0.001). Conclusions PLR in peripheral blood has certain reference value for therapeutic effect and prognosis evaluation on NSCLC with EGFR-mutation. Low PLR of NSCLC patients with EGFR-mutation has higher efficacy and longer survival time after targeted therapy, and it is an independent and prognostic factor.
