Biological Therapies Following Peripheral Stem Cell Transplantation in Treating Patients With Non-Hodgkin's Lymphoma, Hodgkin's Disease, or Advanced Breast Cancer
RATIONALE: Interleukin-2 may stimulate a person's white blood cells to kill cancer cells. Filgrastim and stem cell factor may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of cancer therapy. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by therapy used to kill cancer cells.
PURPOSE: Phase I trial to study the effectiveness of interleukin-2 and stem cell factor following peripheral stem cell transplantation in treating patients who have non-Hodgkin's lymphoma, Hodgkin's disease, or advanced breast cancer.
Drug: recombinant human stem cell factor
Procedure: peripheral blood stem cell transplantation

|Official Title:||Immunotherapy With Subcutaneous Il-2 and Stem Cell Factor (SCF) for Patients With Lymphoma or Breast Cancer After Autologous Transplantation|
|Study Start Date:||May 1999|

OBJECTIVES: I. Determine the safety and maximum tolerated dose of interleukin-2 (IL-2) and stem cell factor (SCF) following autologous peripheral blood stem cell transplantation in patients with non-Hodgkin's lymphoma or advanced breast cancer. II. Determine the effectiveness of filgrastim (G-CSF) and SCF as mobilizing agents in these patients.
OUTLINE: This is a dose escalation study of stem cell factor (SCF). Patients receive filgrastim (G-CSF) subcutaneously (SC) followed by SCF SC daily for 7-10 days. Beginning on the fifth day of G-CSF and SCF injections, peripheral blood stem cells (PBSC) are collected over several days. PBSC are later reinfused and patients receive G-CSF SC daily until hematopoietic recovery. At least 30 days but no later than 110 days following transplant, patients who did not experience adverse reactions to SCF during mobilization begin posttransplant immunotherapy. Patients receive interleukin-2 SC daily and SCF SC 3 times weekly for 6 weeks. Treatment continues in the absence of unacceptable toxicity or disease progression. Cohorts of 3-6 patients receive escalating doses of SCF during posttransplant immunotherapy until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose limiting toxicities. Patients are followed at 1 week, every 3 months for 1 year, and then every 6 months thereafter.
PROJECTED ACCRUAL: A maximum of 27 patients will be accrued for this study within 1-1.5 years.
