Summary

RATIONALE: Biological therapies, such as GM-CSF, may stimulate the immune system in different ways and stop cancer cells from growing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving GM-CSF together with rituximab may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving GM-CSF together with rituximab works in treating patients with previously untreated follicular non-Hodgkin lymphoma.

Detailed description

OBJECTIVES: Primary * Evaluate the clinical efficacy of sargramostim (GM-CSF) and rituximab, in terms of overall objective complete and partial response rates, in patients with previously untreated follicular non-Hodgkin lymphoma. Secondary * Evaluate the time to progression in patients treated with this regimen. * Evaluate the overall survival of patients treated with this regimen. * Evaluate the duration of response in patients treated with this regimen. * Evaluate the safety profile of this regimen in these patients. * Evaluate the influence of FcγR polymorphisms on clinical response. * Monitor FcγR-expressing cells in peripheral blood during treatment. * Monitor the molecular biological marker bcl2 \[t(14;18)\] in peripheral blood and bone marrow. OUTLINE: This is a multicenter study. * Induction therapy: Patients receive sargramostim (GM-CSF) subcutaneously (SC) on days 1-5 and rituximab IV on day 1. Treatment repeats every 21 days for up to 8 courses in the absence of disease progression or unacceptable toxicity. * Maintenance therapy: Patients receive GM-CSF SC on days 1-5 and rituximab IV on day 1. Treatment repeats every 8 weeks for up to 12 courses in the absence of disease progression or unacceptable toxicity. Blood and bone marrow samples are collected at baseline and periodically during study for analysis of bcl2 rearrangement by PCR assay; FcγR expression by immunophenotyping; and FcγR polymorphisms. After completion of study therapy, patients are followed every 3 months for 1 year and then every 6 months for up to 4 years.
