One of the antigens, OX-TES-1, was recognised by serum from four out of 10 patients with DLBCL, one out of 20 normal serum samples and no acute myeloid leukaemia (AML) or chronic myeloid leukaemia (CML) serum samples (n=10 of each). Here, PASD1 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
