Expression data of chronic lymphocytic leukemia patient samples from the REACH study

We assessed genome-wide expression of available pretreatment specimens from CLL patients enrolled in REACH, a study of fludarabine and cyclophosphamide FC or R-FC (addition of rituximab to FC) in relapsed CLL, to understand the disease heterogeneity and explore genes that may be prognostic or predictive of benefit from R-FC treatment. REACH (NCT00090051) was registered at www.clinicaltrials.gov. This dataset supports the manuscript "PTK2 expression and immunochemotherapy outcome in chronic lymphocytic leukemia" by Weisser et al. 300 available pretreatment specimens from patients enrolled in REACH trial were analyzed.
