What was measured

DFS was defined as the time from date of initial CR/CRu to the date of relapse or death from any cause. Tumor response was assessed according to criteria published by Cheson et al (1999). Relapse was defined as a new lesion or increase by ≥50% in size of previously involved sites, or ≥50% increase in greatest diameter of any previously identified node \>1 cm, following an earlier assessment of CR or CRu.

Analysis population: ITT Population (Responder Subpopulation).

Groups in this outcome

Rituximab SC

Participants with previously untreated, CD20-positive DLBCL received up to 8 cycles of rituximab in combination with CHOP. Treatment was given on Day 1 of each cycle, and the cycle length (14 or 21 days) was decided by the study center. For Cycle 1, rituximab was administered at a dose of 375 mg/m\^2 via IV infusion; subsequent doses were given as 1400 mg via SC injection. Tumor response was assessed after 4 cycles according to criteria published by Cheson et al (1999), which are presented in Outcome Measure 1. The duration of CHOP therapy could be reduced from 8 to 6 cycles for those who achieved CR or CRu after 4 cycles, but all participants received a full 8 cycles of rituximab.

Rituximab IV

Participants with previously untreated, CD20-positive DLBCL received up to 8 cycles of rituximab in combination with CHOP. Treatment was given on Day 1 of each cycle, and the cycle length (14 or 21 days) was decided by the study center. For all cycles, rituximab was administered at a dose of 375 mg/m\^2 via IV infusion. Tumor response was assessed after 4 cycles according to criteria published by Cheson et al (1999), which are presented in Outcome Measure 1. The duration of CHOP therapy could be reduced from 8 to 6 cycles for those who achieved CR or CRu after 4 cycles, but all participants received a full 8 cycles of rituximab.
