Serum lipoproteins and cancer
Abstract
In haematological and solid tumours the blood lipoprotein profile has been reported to be altered; while decreased levels of total cholesterol and increased values of triglycerides have been observed. The mechanism and meaning of these changes are, however, not fully understood. The aim of the present study was to determine relationships between cancer progression and serum lipoproteins. We performed a case-control study. We included cancer patients admitted to the 1st Division of Medical Oncology, Businco Hospital of Cagliari, Italy, between 1984 and 1998; 519 patients with any type of solid tumours and 928 healthy controls. We considered total cholesterol (C), high-density lipoprotein (HDL)-C, low-density lipoprotein (LDL)-C, triglycerides and apolipoprotein A-1; other parameters examined were glycaemia, insulinaemia, body mass index (BMI), homeostasis model assessment-estimated insulin resistance (HOMA-IR), C reactive protein (CRP) and tumour necrosis factor-alpha (TNF-alpha). In the cancer group HDL-C and apolipoprotein A-1 were lower (p<0.05) and triglycerides were higher (p<0.05) than in controls; HDL-C (mg/dl) females: 48 vs. 64; males, 40 vs. 52; Apo-A-1 (mg/dl) females: 125 vs. 173; males, 120 vs. 152; triglycerides (m...Continue Reading

ApoE, Lipids & Cholesterol
Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
