...we aimed to evaluate the effectiveness and safety of endostatin combined with PD-1 antibody plus chemotherapy as the first-line treatment for locally advanced or distant metastatic NSCLC with EGFR/ALK-negative….The median PFS and OS were 22.0 months (95% confidence interval [CI]: 16.6-27.4 months) and 31.0 months (95% CI: 23.4 months-not reached [NR]), respectively, with a median follow-up of 21.4 months (range, 8.3-44.4 months)....In the real-world scenario, endostatin combination with PD-1 antibody plus chemotherapy obtained encouraging efficacy and favorable safety in advanced or metastatic NSCLC.
