Study of blood ferritin in cancer patients and its possible use as an indicator of an unfavorable prognosis

: Ferritinaemia levels were measured in 97 neoplastic patients and compared with the levels found in a healthy control group, in order to discover whether ferritinaemia had any significance as a neoplastic marker. Higher levels were encountered in all neoplastic patients (P less than 0.005) than in the control group. Levels were particularly high in the patients with metastasised tumours (especially breast cancer: P less than 0.001). The highest ferritinaemia levels were found in terminal patients (P less than 0.001).
