Current practice of darbepoetin alfa in the management of haemoglobin levels in cancer patients undergoing chemotherapy – data from the CHOICE study

AbstractObjective:To evaluate adherence to European Organisation for Research and Treatment of Cancer (EORTC) and European Summary of Product Characteristic (SmPC) guidance on recommended haemoglobin (Hb) values in routine clinical practice use of darbepoetin alfa (DA) in cancer patients internationally.Methods:This multicentre, prospective, observational study assessed DA use in 11 European countries. This interim analysis (IA) included ∼1300 breast, colorectal, ovarian or lung cancer patients receiving DA during any chemotherapy cycle. Hb level and red blood cell (RBC) transfusion requirement data were collected.Results:Of the 1290 patients (mean [SD] age 62.5 [11.1] years) included in this IA full analysis set, 499 had lung, 387 breast, 192 colorectal and 212 ovarian cancer. Mean baseline Hb levels were 12 g/dL, 226 (18%) of <10 g/dL and 473 (37%) had missing Hb values. 54% of the 672 patients still on the study at week...
