FCN3 and cancer: No impact of ficolin-3 on the incidence of infections or febrile neutropenia in adult patients with haematological malignancies was reported earlier by Kilpatrick et al. [111], Ameye et al. [119] or Islak Mutcali et al. [121] Low ficolin-3 concentration was, however, suggested to be a risk factor for febrile neutropenia (especially with bacteraemia) in paediatric cancer patients, treated with chemotherapy [122].
