简要总结
RATIONALE: Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining biological therapy with chemotherapy may kill more cancer cells.
PURPOSE: Phase I trial to study the effectiveness of biological therapy after chemotherapy in treating patients who have relapsed or refractory non-Hodgkin's lymphoma.
详细描述
OBJECTIVES:
Primary
- Determine the safety and toxicity of cellular immunotherapy with autologous CD8+ cytotoxic T-lymphocyte clones after chemotherapy comprising cyclophosphamide, vincristine, and prednisone in patients with relapsed or refractory CD20+ indolent lymphomas or mantle cell lymphoma.
Secondary
- Determine the duration of in vivo persistence of adoptively transferred CD20-specific CD8+ cytotoxic T-lymphocyte clones in the absence and presence of subcutaneous interleukin-2 in these patients.
- Assess the trafficking of CD8+ cytotoxic T-lymphocyte clones to lymph nodes in these patients treated with this regimen.
- Determine immune response and tumor response in patients treated with this regimen.
