In patients with NO detectable TP53 mutation, CHOP-RIT is associated with longer PFS. (A) There is a trend to longer PFS with CHOP-RIT similar to that previously published for the entire study.¹⁷ (B) Removing the 37 patients with TP53 mutations, the PFS was significantly longer on the RIT-CHOP arm compared with the R-CHOP arm. (C) In the subset of 37 patients with a TP53 mutation, there is an opposite trend with shortened PFS on the RIT-CHOP arm. (Red, RIT-CHOP; Blue R-CHOP).
