“…The ideal candidates for intensive strategies are patients aged 65 years or younger without significant comorbidities, while non-intensive strategies are reserved for elderly patients of more than 65 years or patients with significant comorbidities [98]. Several historical clinical trials have evaluated efficacy of various treatment regimens with respect to partial response (PR), complete response (CR), overall response rate (ORR), and OS; these have included CHOP, R-CHOP, Maxi-R-CHOP (R-CHOP followed by higher doses of cytarabine, followed by an autologous stem cell transplant); R-hyper-CVAD (Rituximab, cyclophosphamide, vincristine, doxorubicin, and dexamethasone alternating with high-dose cytarabine and methotrexate) with or without autologous stem cell transplantation; BR (Bendamustine and Rituximab); R-FCM (Rituximab, fludarabine, cyclophosphamide, and mitoxantrone); R-DHAP (Rituximab, dexamethasone, cytarabine and cisplatin); R-CVP (Rituximab, cyclophosphamide, vincristine, and prednisone); R-CBP (Rituximab, cyclophosphamide, bortezomib, and prednisone); R-VAD+C (Rituximab, vincristine, doxorubicin, dexamethasone, chlorambucil); and RiPAD+C (rituximab, bortezomib, doxorubicin, dexamethasone, and chlorambucil) (Table 2).…”
