Abstract

Introduction: INFL comprises a rather heterogeneous subgroup of lymphomas,including small lymphocytic lymphoma (SLL), immunocytoma (IC) and marginalzone lymphomas (MZL). In April 2002, the GISL started a phase II trial to verifythe efficacy of fludarabine and cyclophosphamide (Flu–Cy) combination in this subsetof NHL, in terms of response, survival and toxicity.Patients and methods: Patients should have a diagnosis of SLL, IC, MZL or CD5negative mature B-cell leukemia (MBCL), supported by morphologic, phenotypicand molecular data; patients should also be untreated for lymphoma and have activedisease defined by the presence of anemia, thrombocytopenia, bulky disease, rapidlyincreasing lymphocytosis or enlarging masses. Treatment consisted of fludarabine25 mg/m2 i.v. day 1–3 and cyclophosphamide 250 mg/m2 i.v. days 1–3, to berepeated every 28 days for six cycles; an intermediate evaluation of response afterthree cycles was planned and an adequate anti-infective prophylaxis was mandatory.Results: As of March 2004, 44 patients were registered into the trial; one patientwas excluded from the study due to incorrect histology. Median age was 63 years(range 39–75), M/F ratio was 1.9. The diagnosis was SLL in 11 patients, IC in 7,MZL in 19 and MBCL in 5. All patients had stage IV disease. Anemia was presentin 32%, elevated b2 microglobulin in 56%, abnormal LDH in 32%. At the time ofthe present analysis, 24 patients completed the treatment program with 13 CR (52%)and 11 PRs (44%).
