SF serum Ferritin
It is widely accepted that there is a strong relationship between iron levels and cancer. .
Serum ferritin levels are elevated in many malignancies.
Gynecological malignant tumor patients with high serum ferritin levels have significantly less survival time than patients with low or normal serum ferritin levels.
Ferritin is the primary intracellular iron-storage protein, with small amounts released into circulation. Biologically, ferritin buffers iron to prevent oxidative damage. Clinically, serum ferritin is a composite signal reflecting iron stores and inflammation.
Key point: In cancer, ferritin behaves more like an inflammatory biomarker than a pure iron marker.
In oncology, high ferritin usually reflects one or more of the following:
-IL-6–driven inflammation (acute-phase response)
-Iron sequestration (functional iron deficiency despite high ferritin)
-Tumor-associated macrophage activity
-Cell death and tissue breakdown
-Liver involvement (secondary contributor)
Thus, ferritin integrates immune activation + metabolic stress.
