EPHA5 mutation was associated with adverse outcome of atezolizumab treatment in late-stage non-small cell lung cancers.

ABSTRACT:

Background

The aim of the study was to investigate predictive value of gene mutation for atezolizumab treatment response from OAK and POPLAR cohorts.

Methods

Several public databases were used for analyzing gene mutation type of EPHA5 and association with alterations of other genes. Survival analysis was performed for patients receiving atezolizumab from OAK and POPLAR cohorts.

Results

EPHA5 mutation have high frequency to harbor TP53 and KEAP1 mutations. The bTMB value has significant difference between EPHA5 mutant and wild-type cases. Patients with EPHA5 mutation got worse survival compared to those without gene mutations receiving atezolizumab (P = 0.0186).

Conclusions

EPHA5 mutant NSCLC may represent a subpopulation which showed worse response after treatm
