The following studies established R-CHOP as the standard regimen for newly diagnosed patients with DLBCL. Dose intensification of R-CHOP by a 14-day versus a 21-day cycle did not result in improved outcomes.
R-CHOP showed improvement in event-free survival (EFS) and overall survival (OS) compared with CHOP alone in 399 advanced-stage patients with DLBCL older than 60 years (EFS, 57% vs. 38%; P = .002, and OS, 70% vs. 57%; P = .007 at 2 years).[Level of evidence: 1iiA] At 10-years' median follow-up, the OS of patients who received R-CHOP compared with patients who received CHOP was 44% versus 28%, P < .0001.
Similarly, for 326 evaluable patients younger than 61 years, R-CHOP showed improvement in EFS and OS compared with CHOP alone (EFS, 79% vs. 59%, P = .001, and OS, 93% vs. 84%, P = .001 at 3 years).[Level of evidence: 1iiA]
A randomized study (DSHNHL-1999-1A [NCT00052936]) of 1,222 patients older than 60 years compared R-CHOP given every 2 weeks for six or eight cycles to CHOP given every 2 weeks for six or eight cycles. With a median follow-up of 72 months, the EFS favored R-CHOP given every 2 weeks for six or eight cycles (EFS at 6 years, 74% vs. 56%; P < .0001). The OS favored R-CHOP for only six cycles because of increased toxicity in the eight-cycle arm (OS at 6 years, 90% vs. 80%; P = .0004).[Level of evidence: 1iiA] There was no comparison to standard R-CHOP or CHOP given every 3 weeks.
