least 25% enlargement or the appearance of new lymph nodes) that
persists for at least 4 weeks despite concurrent or prior drug
treatment OR

- Follicular center lymphoma (grade I or II)

- Diffuse (predominately small cell type)

- Marginal zone, B-cell lymphoma

- No transformed lymphoma

- Failure of at least 1 prior regimen OR

- At least 3 of the following risk factors:

- Over 60 years of age

- Performance status greater than 1

- LDH greater than normal

- More than 1 site of extranodal disease

- Disease stage III or IV

- Mantle cell lymphoma

- Any stage

- Ineligible for protocol CALGB-59908

- At least 1 prior treatment regimen

- At least 1 of the following:

- Immunophenotypic expression of CD5 and CD19 and absence of CD23

- No age restriction NOTE: 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.
