ObjectivesThe CHOICE study was a prospective, multicentre, observational study designed to assess levels of adherence in current clinical practice to the European product label and EORTC guidelines for the treatment of chemotherapy-induced anaemia (CIA) with darbepoetin alfa (DA). Here we present data split by tumour types: breast, colorectal, ovarian and lung.MethodsHaemoglobin (Hb) levels and red blood cell transfusion requirements were evaluated among patients with solid tumours in 11 European countries. The primary outcome measure was the proportion of patients with a target Hb level of ≥10-≤12 g/dL.ResultsThe full analysis set included 1887 patients (mean ± SD 62.4 ± 11.4 years); 1585 (84%) had a current disease stage of ≥3. Common chemotherapy regimens were non-platinum + non-taxane based (n = 696 [37%]) or platinum + non-taxane based (n = 660 [35%]). Breast cancer (n = 575): The mean ± SD Hb level at baseline was 9.9 ± 0.8 g/dL (n = 568). Target Hb level was reached by 187 (55%) patients. Colorectal cancer (n = 310): At baseline the mean ± SD Hb level was 9.8 ± 0.8 g/dL (n = 306). Target Hb level was reached by 107 patients (56%). Ovarian cancer (n = 301): The mean ± SD Hb level at baseline was 9.7 ± 0.8 g/dL (n = 294). Target Hb level was reached by 81 patients (44%). Lung cancer (n = 701): At baseline the mean ± SD Hb level was 9.8 ± 0.9 g/dL (n = 692). Target Hb level was reached by 142 patients (39%).SafetyFive severe or life-threatening adverse drug reactions were seen (three patients with breast cancer, one patient with colorectal cancer and one patient with ovarian cancer).LimitationsPotential bias could not be excluded due to the study's observational nature.ConclusionsThis study demonstrates that the recommendations are adhered to in clinical practice, with the mean starting Hb level <10 g/dL irrespective of tumour type. Furthermore, DA is likely to be effective and well tolerated for the treatment of CIA in patients with breast, colorectal, ovarian or lung cancer.
