Collectively, these data show that AGI and PD-L1 both associate with elevated immune expression, but approximately 80% of AGI cases were PD-L1-low, while approximately 12% of cases with no genomic instability (NGI) were identified as PD-L1-high (Fig. 3C), highlighting the importance of both markers for capturing immunogenic breast cancers. This evidence concerns the gene CD274 and breast cancer.
