- ANC ≥ 1500/mmc unless due to marrow involvement by lymphoma and/or platelets ≥
100000/mmc unless due to marrow involvement by lymphoma

- Serum creatinine ≤ 1.5 x ULN, unless it is disease related

- Bilirubin ≤ 1.5 x ULN (or ≤ 3.0 x ULN, if patient has Gilbert syndrome)

- AST/SGOT and/or ALT/SGPT ≤ 2.5 x ULN if not lymphoma related or ≤ 5.0 x ULN in
case of lymphoma liver involvement

- Not pregnant or breast-feeding

- Willingness to use effective contraception during the study and 3 months after the end
of treatment

carcinoma in situ of the cervix, or other cancer from which the patient has been
disease-free for ≥ 5 years (see Exclusion criteria 14)

Exclusion Criteria:

- Grade IIIb FL, transformed FL or histologies different from FL

hepatitis B virus vaccination and patients HbcAb positive and HbsAg negative with
undetectable serum HBV-DNA. Occult carriers: must receive treatment with Lamivudine

cessation; HBV-DNA levels and HBsAg will be monitored every month

corticosteroids

- Active bacterial, viral, or fungal infection requiring systemic therapy

- Any concurrent medical or psychiatric condition which might impair administration of
therapy or preclude the ability to give informed consent

- Treatment with an experimental agent within 30 days prior to study entry

- Myelosuppressive chemo or biological therapy within three weeks before study entry
(use rituximab course delivered as maintenance is not an exclusion therapy)
