PD-L1+/EMT+ CTCs were associated with significantly poorer survival after curative surgery, showing that PD-L1 expression and Epithelial Mesenchymal Transition (EMT) of CTCs are negative survival predictors for Non-small cell lung cancer (NSCLC) patients (Janning et al., 2019; Manjunath et al., 2019). Here, CD274 is linked to non-small cell lung carcinoma.
