Furthermore, in the context of fine-needle aspiration cytology (FNAC), the utilization of specific markers such as CD15, CD30, and PAX5 has proven to be valuable for the identification of Hodgkin lymphoma (HL) and non-Hodgkin large B-cell lymphoma, specifically diffuse large B-cell lymphoma (DLBCL). This evidence concerns the gene FUT4 and diffuse large B-cell lymphoma.
