Peripheral Stem Cell Transplantation in Treating Patients With Relapsed Low- or Intermediate-Grade Non-Hodgkin's Lymphoma

You may be eligible if

• DISEASE CHARACTERISTICS: Diagnosis of relapsed low or intermediate grade B-cell non-Hodgkin's lymphoma CD20+ or CD19+ tumor cells Bone marrow involvement less than 20% of intratrabecular space All tumor masses less than 5 cm in each dimension In second or greater remission with either complete remission or minimal disease state OR Failed to achieve remission with primary induction therapy, but can achieve minimal disease with additional chemotherapy or radiotherapy OR Persistent splenomegaly with otherwise minimal disease No active CNS involvement A new classification scheme for adult non-Hodgkin's lymphoma has been adopted by PDQ. The terminology of "indolent" or "aggressive" lymphoma will replace the former terminology of "low", "intermediate", or "high" grade lymphoma. However, this protocol uses the former terminology.
• PATIENT CHARACTERISTICS: Age: 18 to 65 Performance status: ECOG 0-2 Life expectancy: Not specified Hematopoietic: Absolute neutrophil count at least 1500/mm3 Platelet count at least 100,000/mm3 Hepatic: Bilirubin no greater than 2.0 mg/dL Renal: Creatinine no greater than 2.0 mg/dL Cardiovascular: LVEF at least 45% Pulmonary: DLCO at least 50% predicted Other: Not pregnant Negative pregnancy test No prior other malignancy except carcinoma in situ of the cervix or basal cell carcinoma of the skin No known hypersensitivity to nickel No known hypersensitivity to mouse proteins HIV negative HTLV I and II negative
• PRIOR CONCURRENT THERAPY: Biologic therapy: At least 3 months since prior unconjugated anti-B-cell monoclonal antibody (mAb) (e.g., rituximab, Campath I) No prior anti-B-cell mAb conjugated to radioisotopes such as iodine I 131 (e.g., iodine I monoclonal antibody anti-B1) or yttrium Y No concurrent mAb therapy until 12 months after study No other biologic therapy (e.g., monoclonal antibodies, interferon alfa) for 12 months after study No concurrent hematopoietic growth factors other than filgrastim (G-CSF) Chemotherapy: See Disease Characteristics No chemotherapy within 5 days prior to PBSC collection No other concurrent chemotherapy for 12 months after study Endocrine therapy: Not specified Radiotherapy: See Disease Characteristics No concurrent radiotherapy for 12 months after study Surgery: Not specified
