Abstract

Background

Advanced ALK-rearranged non-small cell lung cancer (NSCLC) patients will develop acquired resistance after anaplastic lymphoma kinase (ALK) inhibitors therapies. Vascular endothelial growth factor-A (VEGF-A) production and tumor vessel formation were found to be more significantly enriched in ALK-rearrangement NSCLC than that in epidermal growth factor receptor or Kirsten rat sarcoma viral oncogene mutated NSCLC. However, the correlation between ALK rearrangement and the efficacy of bevacizumab (a recombinant humanized IgG1 monoclonal antibody targeting VEGF-A) was still elusive.

Case presentation

We report a case with metastatic NSCLC harboring ALK-rearrangement who was initially resistant to two courses of ALK-Tyrosine Kinase Inhibitor (TKI) therapy, but got a clinical benefit of 7 months of progression free survival after the combined treatment of bevacizumab plus pemetrexed. And the patient tolerated well.

Conclusions

It suggested that bevacizumab combined with pemetrexed might be a preferred option for ALK rearrangement patient who had failed no less than two courses of ALK-TKIs.
