DA-REPOCH Versus R-CHOP for the Treatment of Activated B-Cell Subtype Diffuse Large B-Cell Lymphoma: A Community Center Experience.

Diffuse large B-cell lymphoma (DLBCL) represents around one quarter of non-Hodgkin lymphomas in both the United States and globally. The activated B-cell (ABC) subtype of DLBCL is associated with higher relapse rates and a worse prognosis when treated with standard regimens in comparison to other subtypes of DLBCL. Recent studies have demonstrated a potential benefit with combination of dose-adjusted rituximab, etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (DA-REPOCH) in comparison to standard combination chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in ABC DLBCL patients. We aimed to see if there was any benefit on progression-free survival (PFS) and overall survival (OS) in a pooled patient population from a community oncology practice with the use of DA-REPOCH in ABC DLBCL. Our study did not reveal a statistically significant advantage in either PFS or OS with DA-REPOCH; however, a smaller percentage or patients progressed or relapsed when treated with DA-REPOCH. While the toxicity profile was similar, a higher percentage of patients receiving R-CHOP experienced grade 3 or higher toxicities. A prospective trial of R-CHOP versus DA-REPOCH in patients with the ABC subtype of DLBCL is warranted to further determine a potential benefit to DA-REPOCH in this patient population.
