Proliferative index and CD15 expression in pediatric classical Hodgkin lymphoma

Abstract

Loss of CD15 expression in CHL might be related to p53 dysregulation. High PI in HL might reflect a high level of endomitosis within tumor cells, and could lead to higher sensitivity to chemotherapy. Low pre-treatment PI and lack of CD15 expression were found to be predictive factors for poor FFS in pediatric CHL.
