Oral fludarabine and rituximab as initial therapy for chronic lymphocytic leukemia or small lymphocytic lymphoma: population-based experience matches clinical trials

Abstract

Clinical trials report that fludarabine and rituximab (FR) as initial therapy for chronic lymphocytic leukemia (CLL) improves progression-free and overall survival (OS) when compared historically to fludarabine alone. To determine whether similar results are achievable with oral FR in a community-based setting, we conducted a population-based analysis of patients treated for CLL or small lymphocytic lymphoma (SLL) in British Columbia, where FR is standard initial therapy. Ninety-eight patients received FR for CLL/SLL from 2004 to 2009. Two- and 4-year OS was 90% and 73%, respectively (median not reached); 2- and 4-year treatment-free survival (TFS) was 69% and 54% (median 4.0 years). Age ≥ 60 years or ≥ 70 years had no effect on OS or TFS. Toxicity led to treatment discontinuation in 13%. FR with oral fludarabine was safely, conveniently and successfully given to community-based patients, irrespective of age, for first-line therapy for CLL/SLL, achieving OS and TFS similar to those in clinical trials.
