Background: Lung cancer is one of the deadliest cancers in the world with the highest incidence and mortality rate among all cancers. Non-small cell lung cancer (NSCLC) accounts for approximately 80% of primary lung cancer. However, efficacy and safety of the current regimens for NSCLC is unsatisfactory. Therefore, there has been an increasing urgency for development of potential therapeutic therapies for NSCLC.
Aim: To investigate the therapeutic outcomes and safety of continuous intravenous infusion of recombinant human endostatin (Rh-endostain) using an infusion pump in retreated advanced NSCLC.
Methods: Patients with retreated advanced NSCLC who were admitted to Zhejiang Provincial People's Hospital from October 2017 to April 2019 were recruited. These patients received continuous intravenous infusion of Rh-endostain using an infusion pump. Objective response rate (ORR), clinical benefit rate (CBR), median progression-free survival (mPFS), and incidences of adverse events (AEs) were analyzed after treatment.
Results: A total of 45 patients with retreated advanced NSCLC were included, and all of them were evaluated. In these patients, ORR was 22.2%, CBR was 84.4%, and mPFS was 5.3 mo. The following AEs were observed, decreased hemoglobin (34 cases, 75.6%), nausea/vomiting (32 cases, 71.1%), elevated transaminase (24 cases, 53.3%), leukopenia (16 cases, 35.6%), thrombocytopenia (14 cases, 31.1%), and constipation (1 case, 3.4%). None of the patients had leukopenia, nausea /vomiting, and constipation of grade III and above.
Conclusion: The patients showed improved adherence to 5-d continuous intravenous infusion of Rh-endostain using an infusion pump. Favorable efficacy and safety of this treatment regimen were achieved in retreated advanced NSCLC.
