“…The pooled frequency of PE in RCTs is 2.3% (66 of 2,903), ranging from 1.3% to 21.4% 12 - 24 , of all the highest rate (21.4%) of PE occur in the process of chemotherapy where nab-paclitaxel was used to treat patients with advanced NSCLC who failed first-line chemotherapy 16 followed by 8% in a RCT for the evaluation of pemetrexed plus cisplatin in combination with or without LY2603618 (a selective checkpoint kinase 1 inhibitor) in patients with advanced nonsquamous NSCLC 12 , impling the incidence of PE in various RCTs for lung cancer patients could be high. The PE rate is lower in lung cancer patients only undergoing lung resection (1.6%, 59 of 3,718, range: 0-2.7%) 25 - 27 , 29 , 34 , 37 , 41 , 43 , 45 , 46 than those only receiving nonsurgical therapy (5.0%, 618 of 12,239, range: 1.3%-21.4%) 11 - 21 , 23 , 24 , 28 , 32 , 33 , 36 , 44 , 51 , yet than those receiving comprehensive therapy (surgical and nonsurgical) (2.5%, 279 of 10,962, range: 0-13.3%) 22 , 30 , 35 , 38 , 39 , 47 - 50 . These results imply that the risk of PE in lung cancer patients receiving nonsurgical therapy is higher than those only undergoing lung resection.…”
