      • Abstract

      Background:
      Effective treatment options are limited for advanced non-small cell lung cancer (NSCLC) patients who progressed after first-line therapy. Pronounced efficacy of anti-programmed cell death protein 1 (anti-PD-1) combination strategy was observed in first-line setting, therefore we assessed whether the addition of chemotherapy and/or bevacizumab to anti-PD-1 could improve clinical outcomes in second-line or later advanced NSCLC.


      Method:
      Advanced NSCLC patients treated with anti-PD-1 therapy from March 2015 to July 2017 were retrospectively screened for eligibility. First-line treatment or combined drugs beyond chemotherapy or bevacizumab were excluded. The primary objective was progression-free survival (PFS). Secondary objectives were overall response rate (ORR), disease control rate (DCR) and safety.


      Results:
      55 patients were included in the analysis (monotherapy, n=33; combination therapy, n=22). 90.0% of the patients have progressed after standard platinum-based chemotherapy in previous line therapies. Combination group exhibited longer PFS than monotherapy group (median, 7.5 vs 3.3 months, adjusted HR 0.32[0.16-0.65], P =0.001). 31.8% (7/22) patients in combination group achieved an objective response compared with 10.0% (3/30) in monotherapy group (P = 0.075). The DCR was 95.5% (21/22) in combination group compared with 46.7% (14/30) in monotherapy group (P<0.001). Adverse events of grade 3 or worse were occurred in 22.7% of the patients in the combination group and in 6.1% of those in monotherapy group. Most of the adverse events were manageable.


      Conclusion:
      Combination of anti-PD-1 plus chemotherapy and/or bevacizumab could be an effective and tolerable therapy as second-line or later treatment option for advanced NSCLC patients.
