Eligibility Criteria:
DISEASE CHARACTERISTICS: Histologically proven relapsed or refractory, low grade or transformed low grade B-cell non-Hodgkin's lymphoma including the following: Small lymphocytic Follicular small cleaved cell Follicular mixed small cleaved and large cell (less than 50% large cell component) Tumor must be positive for CD20 antigen Relapse or disease progression following at least 1 chemotherapy regimen or failure to achieve an objective response (complete or partial response) on prior chemotherapy regimen No disease progression, within 1 year of irradiation, arising in a field previously irradiated with more than 3500 cGy Mean of no greater than 25% intratrabecular marrow space involved with lymphoma on bilateral iliac crest bone marrow biopsy A new classification scheme for adult non-Hodgkin's lymphoma has been adopted by PDQ.
