This result was comparable to studies conducted by Hollander et al., where PD-L1 expression was found to be maximum in the nodular sclerosis subtype (78%), followed by the mixed cellularity subtype (20%), and only 3% in the lymphocyte-rich + lymphocyte-depleted + unclassifiable subtype of HL [13]. The gene discussed is CD274; the disease is Hodgkins lymphoma.
