133 Background: Pemetrexed combined with platinum was the standard treatment for first-line EGFR wild type non-squamous NSCLC , but further research is needed to confirm the safety of pemetrexed and bevacizumab treatment in maintenance therapy after first-line treatment in advenced non-squamous NSCLC. Methods: Total 60 patients with newly diagnosed advanced non-squamous NSCLC admitted to the hospital from June 2015 to June 2017, which were ARMS confirmed the EGFR wild type. In the observation group, bevacizumab +pemetrexed+ platinum was maintained with bevacizumab (BAP-B group). Control group: bevacizumab + pemetrexed + platinum was maintained with pemetrexed (BAP-A group). 60 patients completed 4- 6 cycles of chemotherapy and maintenance therapy for more than 4 cycles. The curative effect was evaluated According to Recis 1.1.The toxic reaction was evaluated WHO chemotherapeutic drug toxicity. The quality of life of patients were evaluated by EORTC QLQ-LC43. All the data were processed by SPSS19.0. P 0.05);DCR 73.5 & 64.8 % ( P>0.05), median PFS 9.6 m & 7.2 m (P < 0.05), OS:18.2 m & 12.6 m (P < 0.05). Adverse incidence: BAP-B & BAP-A: leukopenia rate 43.0% & 41.2% hemoglobin reduction 40.0% & 38.5%; The reaction rate of digestive tract was 35.3% & 34.5%. There was no significant difference between the two groups. The incidence of hypertension in BAP-B (18.8%) was higher than that in BAP-A (0%) (P < 0.05). The incidence of proteuria in BAP-B (8.8%) was higher than that in BAP-A (2.0%) (P < 0.05), BAP-A and BAP-B (P < 0.05). The quality of life score of EORTC QLQ-C43 was (73.17 ±2.75) & (59.68 ±2.52), which was higher than that before treatment (52.75 ±2.02) & (53.01 ±1.98), and the score of BAP-A was higher than that of BAP-B(P < 0.05). Conclusions: The first line treatment of advanced EGFR wild type non-squamous NSCLC needs comprehensive consideration of curative effect, survival time, safety, quality of life and economic problems in order to choose the most suitable treatment.
