Abstract

Background: Limited progress had been made in prognostic stratification of patients with Hodgkin lymphoma (HL) until recent studies suggested that the number of CD68-expressing macrophages is prognostic in classical HL. However, its significance in Asian patients with HL has not been explored yet perhaps because of its low incidence in Asia. Methods: In this work, we performed immunohistochemical analysis of CD163, as well as CD68, in 144 Korean patients with HL treated between November 1990 and December 2009 in a single center. The relative percentages of CD68+ and CD163+ cells with respect to the overall cellularity (CD68 index and CD163 index, respectively) were correlated with clinical outcomes. Results: Both high CD68 and CD163 indices (>20%) were associated with a rise in treatment-related deaths and poorer event-free survival (P=0.009 and P=0.0023, respectively), disease-specific survival (P=0.011 and P=0.001), and overall survival (P=0.023 and P=0.001). In particular, a high CD163 index was related to lower complete response (CR) rate (P=0.022) and shorter duration of CR (P=0.030). Conclusions: High index of either CD68 or CD163 (>20%) is significantly correlated with poor prognosis in Korean patients with HL. CD163, a specific marker of macrophages, seems to be another prognostic factor for classical HL.
