There were no significant variations in progression\free survival of second\collection treatment between the groups in the overall human population: 2.6, 3.7, and 3.2 months in the Bev 1st\collection, Bev second\collection, and Bev cross\lines groups, respectively (= 0.796). No statistically significant improvement in objective response or disease control rates in the Bev mix\lines group was observed. No unpredicted or severe adverse events were recorded. Conclusion We found no benefit in continuing Bev treatment beyond progression after 1st\collection treatment comprising Bev for individuals with advanced NS\NSCLC. Further study of validated predictive biomarkers of response to Sele treatment after long\term antiangiogenic therapy is required. mutations, or or rearrangements. Currently, there is no standard treatment routine for individuals who encounter disease progression after 1st\collection treatment. Evidence from preclinical and medical studies has shown 1,2-Dipalmitoyl-sn-glycerol 3-phosphate the continuation of Bev combined with chemotherapy might be a second\collection treatment option. Preclinical data suggests that VEGF is definitely continually indicated during tumor growth and tumor progression, and prolonged VEGF inhibition achieves and maintains tumor regression and delays tumor growth.12, 13, 14, 15, 16, 17 This concept has been supported by the data of individuals with metastatic colorectal malignancy in the clinical setting. Two non\randomized observational cohort studies (BRiTE18 and ARIES19) reported the 1,2-Dipalmitoyl-sn-glycerol 3-phosphate continuation of Bev beyond 1st progressive disease (PD) of 1st\collection Bev plus chemotherapy could improve post\progression survival. AvaALL (MO22097), the 1st randomized phase IIIb study assessing the effectiveness of continuing Bev beyond PD after 1st\collection treatment in NSCLC showed prolonged progression\free survival (PFS) in third\collection treatment, but no statistically significant improvement in overall survival (OS) in individuals continuing Bev across multiple treatment lines compared to individuals who received chemotherapy only in subsequent lines.20 Although an increasing number of studies possess explored the continuation of Bev, limited data are available on Bev continuation in subsequent lines of treatment after first PD in individuals with NSCLC in a real world setting. Whether long\term Bev can prolong OS in NSCLC individuals is definitely unfamiliar. This prompted us to perform a retrospective study to evaluate the continuation of Bev in treatment lines beyond 1st PD versus 1st and later collection treatment comprising Bev in individuals with advanced NS\NSCLC. Methods Data source and study population The records of individuals with advanced NS\NSCLC who received Bev between July 2009 and July 2017 were retrospectively collected from your Cancer Hospital, Chinese Academy of Medical Sciences (Beijing, China). Qualified individuals were required to become histologically or cytologically confirmed with stage IIIB or IV (American Joint Committee on Malignancy 7th Edition Tumor Staging Manual) NS\NSCLC. Study subjects were classified into three mutually 1,2-Dipalmitoyl-sn-glycerol 3-phosphate special groups relating to treatment: (i) Bev 1st\collection (Bev1): individuals who received treatment comprising Bev as 1st\collection therapy but no further Bev in second\collection treatment after 1st PD; (ii) Bev second\collection (Bev2), individuals who received 1st\collection therapy without Bev, but received Bev in later 1,2-Dipalmitoyl-sn-glycerol 3-phosphate on\lines of treatment; and (iii) Bev mix\lines (BevCL), individuals who received treatment containing Bev as 1st\collection therapy and continued Bev for a second line of treatment beyond 1st PD. A total of 118 individuals were included in the study. Baseline characteristics were collected for each patient, including age, gender, Eastern Cooperative Oncology Group overall performance status (ECOG PS), smoking history, histology, disease stage, status, status, mind metastasis, and concomitant regimens. Assessment This was a retrospective study with a main outcome of OS and secondary objectives of PFS, objective response rate (ORR), disease control rate (DCR), and security assessment in NS\NSCLC individuals.
