MT is differentially expressed in subclassified Hodgkin lymphoma. The number of MT-I, II immunostained cells is significantly higher in MCHL relative to other subclassified HL groups (p < 0.001), and also, the number of these cells is significantly higher in NSHL relative to NLPHL and LRCHL (p < 0.005). Here, MCAT is linked to Hodgkins lymphoma.
