      Abstract
      Background
      Nivolumab is a fully human IgG4 monoclonal antibody targeting the programmed death-1 (PD-1). It's a standard second-line treatment for advanced NSCLC. Liver metastases(LM) is one of the worst prognostic NSCLC metastatic sites, but the attention to LM is far lower than brain metastases and bone metastases.

      Methods
      Patients with stage IIIB-IV NSCLC treated with second-line or later nivolumab monotherapy were retrospectively collected from January 2016 to July 2018. The patients were divided into two cohorts based on the presence or absence of LM at the time of first dose. Study endpoints included OS and PFS.

      Results
      65 patients were included, including 10 patients with and 55 patients without LM. Baseline characteristics of the two cohorts were comparable, as shown in the below table.

      The median OS of the patients with and without LM was 7.5 and 20.7 months, respectively(HR =4.81;95%CI, 1.28-18.00;p=0.020). Their median PFS was 1.9 and 5.6 months, respectively(HR =4.47;95%CI, 1.61-12.35;p=0.004). COX multivariate regression analysis suggested LM was an independent prognostic factor. Kaplan-Meier curves of OS and PFS were shown in the below figure.



      Conclusion
      The outcome of advanced NSCLC patients with LM treated with Nivolumab monotherapy is relatively poor compared with those without LM.
