Ferric Carboxymaltose in the treatment of chemotherapy-induced anaemia: an effective, safe and cost- sparing alternative to blood transfusion

Anaemia is highly prevalent in cancer patients, adversely affects quality of life and impacts survival. The pathogenesis is multifactorial, with iron deficiency being a major and potentially treatable contributor. This study aimed to assess the effectiveness and economic impact of ferric carboxymaltose in chemotherapy-induced anaemia. This prospective cohort study between 2015–2016 of chemotherapy-treated patients for solid tumours, grade ≥2 anaemia and iron deficiency evaluated hematopoietic response four weeks after ferric carboxymaltose treatment. Transfusion rate of all cancer patients treated at our ambulatory unit during the two-year study period (2015–2016) was compared to a retrospective cohort (2013–2014) who received blood transfusion only. Between 2015–2016, 99 patients were included and treated with ferric carboxymaltose, the majority of whom (n = 81) had relative iron deficiency. Mean haemoglobin concentrations improved from 9.2 [6.7–10.8] g/dL to 10.6 [7.8–14.2] g/dL four weeks after treatment. A 26% reduction in the transfusion rate was observed from control retrospective to the prospective study group including ferric carboxymaltose treated patients [relative risk 0.74 (95% CI:0.66–0.83)]. The cost analysis showed a benefit for the use of ferric carboxymaltose in chemotherapy-induced anaemia. This study shows that ferric carboxymaltose is an effective, cost-saving support treatment, reducing the need for allogeneic transfusions saving blood units which are a limited resource.
