BONE-MARROW HEMOSIDERIN IRON AND SERUM IRON STATUS MARKERS IN SMALL-CELL CARCINOMA OF THE LUNG

Bone marrow haemosiderin iron grade and serum (S-) iron status markers (haemoglobin (Hb), S-iron, S-transferrin, transferrin saturation, S-ferritin) were measured in 31 patients with newly discovered small cell cancer of the lung (SCCL), and compared to the values in 53 healthy control subjects. Among SCCL patients, 2 had grade 0 (absent), 5 grade (1+) (trace), 8 grade 1+ (normal), and 16 grade 2+ (increased) marrow haemosiderin iron. Median S-ferritin values in the respective groups were 38 mug/l, 243 mug/l, 384 mug/l and 433 mug/l. There was no correlation between Hb, S-iron, S-transferrin or transferrin saturation and marrow iron grade. S-ferritin displayed a correlation with marrow iron grade (r(s) = 0.40, p
