“…Moreover, the drug label and current ASH/ASCO guidelines [28,42] generally recommend not to use ESA in patients with curative intent, although convincing data are lacking that transfusions carry a lower risk in this patient group than ESA. By contrast, several recent prospective randomised trials using ESA with curative intent did not provide evidence of an impact on survival or relapse in patients with Hodgkin's lymphoma [46], aggressive lymphoma [47], cervical cancer [48] and early breast cancer [49]. Furthermore, several studies and 3 meta-analyses [20,21,50] have shown that transfusions rather increase the risk of complications such as cardiovascular disease [23], acute lung injury [19], haemolytic reactions [19], postoperative infection [19,20] and surgical re-intervention [20], as well as the risk of relapse [20,21,24], all-cause [19,20,22,23,24,51] and cancer-related mortality [20], and may induce malignant lymphomas [50].…”
