Immunohistochemistry was performed on paraffin sections using anti-CD68 KP1 antibody, and stained macrophages were scored on high-power field (hpf) in either intrafollicular (IF) or extrafollicular (EF) areas.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>For IF MC, the best cutoff point was estimated at 10 macrophages\/hpf. Low IF MC was significantly associated with a better event-free survival (EFS; P = .011). However, this effect was observed only in the CHVP-I arm (P = .012) and not in the rituximab plus CHVP-I arm. Using a cutoff of 15 IF MC, we found no significant association with EFS.
