PD‐L1 and thyroid cytology: A possible diagnostic and prognostic marker

Abstract

The current data suggest that PD-L1 expression in the thyroid gland might represent a marker of malignancy that correlates with PTC, but not with NIFTP. Thyroid neoplasms with PD-L1 expression also ae enriched with BRAF V600E mutations, suggesting that they are associated with more aggressive behavior.
