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.

Objective To evaluate the clinical effects of the totally laparoscopic and laparoscopic-assisted radical gastrectomy for gastric cancer,and evaluate the feasibility and safety of the two methods.Methods Eighty patients with gastric cancer undergoing radical D2 gastrectomy from Mar 2016 to Jul 2017 were enrolled.Patients were divided into totally laparoscopically hand-sewn escophagojejunostomy group (35 cases) and control group of hand-assisted laparoscopic esophagojejunostomy (45 cases).Results Compared with the control group,the operation time,blood loss,lymph node dissection in the control group were not significantly different [(256 ± 53) min vs.(248 ± 62) min,t =2.40,P ＞ 0.05;(123 ±78)ml vs.(162±56)ml,t=-1.94,P＞0.05;(28±6) vs.(30±7),t=-3.18,P＞0.05].The postoperative ambulation time,first exhaust time,postoperative hospital stay,incision complications were all in favor of the totally laparoscopic group [(1.5 ± 0.7) d vs.(2.6 ± 0.6) d,t =-2.41,P ＜ 0.05;(2.7 ±0.8)d vs.(4.0 ±1.2)d,t =-4.63,P＜0.01;(6.8 ±0.8)d vs.(9.2 ± 1.6)d,t =-7.32,P＜0.05].Conclusions Totally laparoscopic radical gastrectomy and hand-sewn esophagojejunostomy for gastric cancer is safe and reliable and has advantages such as less pain and fast recovery.
