Considering that difference in biological character between ABC‐DLBCL and GCB‐DLBCL is based on the distinct role of BCR signal pathway which is a completely different perspective from chromosomal instability, we expect patients with ≥3 CAVs to be found in both ABC and GCB‐DLBCL groups. This evidence concerns the gene BCR and diffuse large B-cell lymphoma.
