Chemoimmunotherapy with cyclophosphamide, doxorubicin, vincristine, prednisolone, and rituximab (R-CHOP) is the standard of care for patients with diffuse large B-cell lymphoma (DLBCL). However, management of elderly patients is challenging as critical comorbidities often account for increased number of treatment-related complications.

Patients and methods:

In the past 8 yrs, we have treated elderly patients with a full-dose R-CHOP regimen by splitting the administration of cyclophosphamide and doxorubicin over 2 days (R-split-CHOP) to reduce peak plasma level. Here, we retrospectively analyzed the results of 30 patients with newly diagnosed DLBCL.


The overall response rate was found to be 87%, the overall survival probability after 3 yrs was 60.6% (95% CI, 42.1%–79.0%), and the progression-free survival probability was 49.7% (95% CI, 30.4%–68.9%). Grade 3/4 infectious complications were reported in 30% of patients, yet no treatment-related deaths occurred.


We suggest that R-split-CHOP could be a valuable option to safely administer full-dose-intensity R-CHOP to elderly patients at risk of treatment-related complications.
