Abstract:
Objective:To preliminarily explore the treatment effect of nivolumab on Chinese non-small-cell lung cancer (NSCLC) patients with brain metastases, and further enrich the evidences of programmed death-ligand 1 (PD-1) monoclonal antibody in the treatment of NSCLC patients with brain metastases.Methods:The clinical and pathological data of 22 NSCLC patients with brain metastases treated with nivolumab were collected. The electronic imaging data were collected to confirm the treatment effect and time point of disease progression, and the survival data of the patients were obtained through follow-up.Results:Twenty-one patients were evaluated for the intracranial treatment effect. The intracerebral objective response rate (IORR) was 28.6%, the intracranial disease control rate (IDCR) was 47.6%. The median intracranial progression-free-survival (iPFS) of all the 22 patients was 5.2 months. Both the 1-year and 2-year survival rates were 56.7%.Conclusions:The treatment effect of PD-1 monoclonal antibody on NSCLC patients with brain metastases is similar as those without brain metastases.
