ALK and T-cell and NK-cell neoplasm: We selected representative genes by merging the RNA sequencing expression data available in the literature [34] and identified a group of genes that were differentially expressed between BIA-ALCL and at least three different T-cell neoplasm entities (e.g., ALCL, AITL, ALK-ALCL, ALK+ ALCL, and PTCL-NOS).
