Key clinical point : High-dose rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-High-CHOP)/cyclophosphamide, high-dose cytarabine, dexamethasone, etoposide, and rituximab (CHASER) followed by high-dose chemotherapy (HDC) with melphalan, cyclophosphamide, etoposide, and dexamethasone (LEED), and autologous peripheral blood stem cell transplantation (auto-PBSCT) provided favorable long-term survival outcomes in younger patients with untreated advanced mantle cell lymphoma (MCL).
Major finding: At 6-year median follow-up, the 5- and 8-year progression-free survival rates were 52.3% (95% CI 36.7%-65.7%) and 17.1% (95% CI 5.2%-34.7%), respectively, and the overall survival rates were 75.0% (95% CI 59.4%-85.3%) and 69.0% (95% CI 52.3%-80.9%), respectively. The incidence of secondary malignancies (11.1%) and continuous relapses was high.
Study details: This final analysis of the JCOG0406 study included 45 patients age ≤ 65 years with untreated advanced MCL who received R-High-CHOP/CHASER followed by HDC with LEED and auto-PBSCT.
