Mannose-binding lectin (MBL) - deficient patients who undergo chemotherapy for a solid tumor might have an increased risk developing febrile neutropenia (FN). We investigated in a prospective cohort study relations between MBL-serum levels and polymorphisms in MBL promotor genotypes (550H/L and 221X/Y) on incidence and severity of FN. Risk of FN was 17.9% in MBL-deficient and 22.5% in MBL-sufficient patients (RR ¼ 0.796, p ¼ 0.45). Median MBL serum levels at baseline were respectively 1.39 mg/mL and 1.09 mg/mL (p ¼ 0.92) in patients with and without FN. In conclusion, serum MBL and MBL genotypes (550H/L and 221X/Y) do not determine the risk for developing FN.
