This study evaluates the efficacy of R-CHOP like chemotherapy in Malaysian patients withDLBCL. Materials and Methods: The study comprised a retrospective analysis of patients with DLBCL treatedat a single centre. The outcome was compared with patients who were treated with R-CHOP like and CHOP likechemotherapy. Patients who were treated with lower dose of rituximab was subanalysed for outcome. Results:A total of 86 patients who had CHOP-like chemotherapy were included. Only 39 (45%) patients had rituximaband only 12 (29%) patients had the recommended dose. The overall response (OR) and complete response(CR) rates were 88% and 81% respectively. There was no significant difference in OR and CR in patients whohad rituximab and those without rituxmab. Those with International Prognostic Index (IPI) score of ≤2 hadsignificant higher CR rate, progression free survival (PFS) and overall survival (p<0.001). Conclusions: The lackof significant improvement in CR and DFS in our patients may be due to an inadequate dose of rituximab.}, keywords = {diffuse large B cell lymphoma,Rituximab,CHOP}, url = {https://journal.waocp.org/article_28815.html}, eprint = {https://journal.waocp.org/article_28815_9a60a35fac778f49ec1cf3ecc212f33c.pdf} }
