Background
Double‐hit lymphoma (DHL) is an aggressive subtype of high‐grade B‐cell lymphoma with inferior prognosis using standard dose chemotherapy. Controversy remains whether more intensive chemotherapy regimens such as dose‐adjusted etoposide, prednisolone, vincristine, cyclophosphamide, doxorubicin and rituximab (DA‐EPOCH‐R) provide better outcomes in this cohort.
Aims
To review consecutive cases of DHL treated with DA‐EPOCH‐R at our institution in comparison to available literature.
Methods
We conducted a retrospective study of 13 consecutive patients with DHL treated with DA‐EPOCH‐R at our institution. Primary endpoints included complete response (CR), event‐free survival (EFS) and overall survival (OS).
Results
CR rate with DA‐EPOCH‐R in DHL was 69% in our cohort. Median EFS and OS duration was 61 months (95% CI: 41–86 months) and 64 months (95% CI: 42–86 months) respectively. One patient discontinued DA‐EPOCH‐R due to recurrent febrile neutropenia and there were no treatment or infection‐related deaths during the study.
Conclusions
This study suggests that DA‐EPOCH‐R is a well tolerated outpatient regimen for DHL and should be considered for initial treatment in medically fit patients. Further prospective studies are warranted to confirm these findings.
