OBJECTIVES:
* Determine the humoral and cellular immune responses in patients with follicular non-Hodgkin's lymphoma treated with autologous lymphoma-derived idiotype vaccine with keyhole limpet hemocyanin plus sargramostim (GM-CSF).
* Determine the safety and toxicity of this regimen in these patients in the post-transplant setting.
* Determine the changes in quantitative bcl-2 in the blood and bone marrow of these patients before and at various times after the series of idiotype vaccines.
OUTLINE: Vaccinations begin at day 100 or up to 6 months after hematopoietic stem cell transplantation. Patients receive autologous lymphoma-derived idiotype vaccine plus keyhole limpet hemocyanin subcutaneously (SC) on day 1. Sargramostim (GM-CSF) SC is administered on days 1-4. Treatment repeats every 4 weeks for 4 doses, followed 12 weeks later by the fifth and final dose.
Patients are followed every 3 months for 2 years, every 6 months for 2 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 20 patients will be accrued for this study.
