ABSTRACT
Aim: Rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) is the standard treatment for
patients with diffuse large B-cell non-Hodgkin lymphoma (DLBCNHL). Nevertheless, anthracyclines are contraindicated for
some patients, e.g. cardiac dysfunction, severe hepatic dysfunction, jaundice. Thus, this study assessed the effectiveness of
non-anthracycline chemotherapy regimen cyclophosphamide, vincristine, and prednisone (CVP) in elderly DLBCNHL patients
vs. the standard CHOP. Methods: This retrospective study included 418 DLBCNHL patients diagnosed between 2003 and 2006
and followed until March 2014. During this period of time, rituximab was not available for all patients, particularly for patients
older than 60 years. Results: CHOP and CVP were administered to 351 (84%) and 67 (16%) patients, respectively. Older age and
comorbidities, particularly cardiovascular and diabetes mellitus, were independent determinants for not receiving CHOP. Patients
received more courses of CHOP treatment than that of CVP (6 vs. 3 courses; P < 0.001) and developed more toxicities (48.4%
vs. 23.9%; P < 0.001), particularly fatigue, alopecia, and gastrointestinal tract toxicities. Complete response rate was higher in
CHOP than in CVP (69.9% vs. 29.9%; P < 0.001). Moreover, early death was signifi cantly higher in CVP group of patients than
in CHOP (43.3% vs. 8.6%; P < 0.001). After a median follow-up of 71 months, the median overall survival (OS) and event-free
survival (EFS) were signifi cantly better in CHOP than in CVP (49.5 vs. 3.7 months and 32.2 vs. 3.5 months; P < 0.001 for
both, respectively). Older age, poor age-adjusted International Prognostic Index scores, not receiving CHOP or consolidative
radiotherapy were independent predictors of poor OS and EFS. Conclusion: Use of the CVP regime to treat DLBCNHL patients
who were unfi t to the standard CHOP treatment was associated with lower remission rates and poorer EFS and OS in this group
of patients.
