Chemo and effect in mantle-cell lymphoma: An approach first a single dose of Rituximab plus cyclophosphamide, vincristine, doxorubicin and dexamethasone (hyper-CVAD) followed by Rituximab plus high-dose methotrexate, cytarabine, high durable remissions observed in new patients with an aggressive form of mantle cell lymphoma. But the side effects and disease-related mortality was high with this approach.
September 14, 2005: Source: J Clin Oncol. 6 September 2005;With an approach first a single dose of Rituximab plus cyclophosphamide, vincristine, doxorubicin and dexamethasone (hyper-CVAD) followed by Rituximab plus high-dose methotrexate, cytarabine, high durable remissions observed in new patients, so had not been treated with an aggressive form of mantle cell lymphoma. A disease-free period of three years was 82% of the patients responding to treatment achieved. However, especially in people over 65 years, adverse events and disease-related deaths is so large that this approach by the investigators is not recommended for this patient group. What is striking is that a whopping 10% of all participating patients died from the effects of treatment, even though some of them achieved remission of their cancer. Especially haematological side effects (blood disorders) were severe and frequent with this approach. Here is the abstract of this phase II study of 97 newly-diagnosed mantle-cell lymphoma patients.

PURPOSE: To determining the response, failure-free survival (FFS) and overall survival rates and toxicity of rituximab plus an intensive chemotherapy regimen in Patients with Previously untreated aggressive mantle cell lymphoma (MCL).
PATIENT AND METHODS: This was a prospective phase II trial of rituximab plus Fractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (hyper-CVAD; Considered one cycle) alternating 21 days everytime with rituximab plus high-dose methotrexate-cytarabine (Considered one cycle) for a total of six to eight cycles.
RESULTS: Of 97 assessable patient, 97% responded, and Achieved a 87% complete response (CR) or CR UNCONFIRMED. With a median follow-up time or 40 months, the 3-year FFS and overall survival rates Were 64% and 82%, respectively, without a plateau in the curves. For the subgroup of Patients = 65 years of age, the 3-year FFS rate was 73%. The principal toxicity was hematologic. Five patients died from acute toxicity. Four patients developed treatment-related myelodysplasia/acute myelogenous leukemia, and three patients died while in remission from MCL. A total of eight treatment-related deaths (8%) occurred.
CONCLUSION: Rituximab plus hyper-CVAD alternating with rituximab plus high-dose methotrexate and cytarabine is effective in untreated aggressive MCL. Toxicity is significant but expected. Because Of The Shorter FFS competitor with significant toxicity in Patients More Than 65 Years of Age, this regimen is not recommended as standard therapy for this age subgroup. Larger prospective randomized studies are Needed to define the role of this regimen in the treatment of lymphoma patient compared with Existing and New treatment modalities.
