[Efficacy of Immune Checkpoint Inhibitors for Non-small Cell Lung Cancer 
with Rare Mutation].

Over the past several decades, advances in driven targeted therapy has revolutionized the management of oncogene-driven non-small cell lung cancer (NSCLC). However, there are only a few targeted drugs available for patients with rare mutations, such as BRAF, HER2, MET, RET, etc. In recent years, immune checkpoint inhibitors (ICIs) have demonstrated promising benefit in NSCLC. Till now, efficacy of ICIs for NSCLC with rare mutation is largely unknown. It is fairly difficult to conduct a large formal prospective controlled trials because of the rarity of these mutation. In this article, currently available real world studies based on convincing clinical evidence will be reviewed, which will ultimately facilitate our rational use of ICIs for NSCLC with rare mutation.
