For primary gastric or cutaneous lymphoma, local/specific previous treatment is accepted, just following the below criteria: Cutaneous lymphoma: recurrent lymphoma after local therapy Gastric lymphoma: b1. H. pylori-negative cases, either de novo (non pre-treated) or at relapse following local therapy (i.e., surgery, radiotherapy or antibiotics). b2. H. pylori-positive cases at diagnosis, who failed antibiotic therapy, including patients with: clinical (endoscopic) and histological evidence of disease progression at any time post H. pylori eradication; stable disease with persistent lymphoma at 1 year post H. pylori eradication; relapse (without H. pylori re-infection), after a remission; patients who failed either first line antibiotics or further local treatment (surgery or radiotherapy) No evidence of histologic transformation to a high grade lymphoma Measurable or evaluable disease Age >18 and <85 ECOG performance status 0-2 Life expectancy of at least 1 year Written informed consent given according to national/local regulations Exclusion Criteria: Prior chemotherapy or prior immunotherapy with any anti-CD20 monoclonal antibody Prior radiotherapy in the last 6 weeks Corticosteroids during the last 28 days, unless prednisone chronically administered at a dose <20 mg/day for indications other than lymphoma or lymphoma-related symptoms Major impairment of renal function (serum creatinine > 2,5 x upper normal) or liver function (ASAT/ALAT <2,5 x upper normal, total bilirubin <2,5x upper normal), unless due to lymphoma involvement. Impairment of bone marrow function (WBC <3.0x109/L, ANC <1.5x109/L, PLT <100x109/L), unless due to lymphoma involvement Evidence of clinically significant cardiac, neurological or metabolic disease, unless due to lymphoma involvement Evidence of symptomatic central nervous system (CNS) disease Active HBV and/or HCV infection Known HIV infection Prior diagnosis of neoplasm within 5 years, except cervical intraepithelial neoplasia type 1 (CIN1) or localized non-melanomatous skin cancer Any psychiatric disease potentially hampering compliance with the study protocol and follow-up schedule Potential to attend regular visits to the hospital, on an outpatient regimen Hypersensibility to any compound of the study medication.
