Childhood cancer survivors lipid and apolipoprotein results were different from controls with higher LDL, Apo-B, Apo-B to A1 ratio, TG and TC levels [mean (SD); LDL (μM), CCS, mean 2.8 (0.7), controls mean 2.2 (0.8), TC (μM) CCS, mean 4.5 (0.9), controls mean 3.8 (0.8), Apo-B (g/L), CCS mean 0.9 (0.2), controls mean 0.7 (0.2), Apo-B/Apo-A1 ratio, CCS mean 0.6 (0.2), controls 0.5 (0.2), TG (μM), CCS mean 1.2 (0.8), controls 0.8 (0.4), P < 0.009 for all]. This evidence concerns the gene APOB and childhood malignant neoplasm.
