title: Plasma lipid alterations in African-American women with breast cancer.
abstract: The purpose of this study was to examine the relationship between plasma lipid and lipoprotein levels, stage of disease and breast cancer risk in African-American women. The study population comprised 163 African-American women: patients (n = 58) and controls (n = 105), with mean ages of 57.2 years and 47.7 years respectively. Approximately 71% and 56% of the women with breast cancer and the control population, respectively, were postmenopausal. Those with cancer had significantly higher education levels, P < or = 0.01, and higher triglyceride levels compared to the controls, P < or = 0.001, but lower body mass index (BMI) levels, P < or = 0.01. There were no statistically significant differences observed in total cholesterol, high-density-lipoprotein-containing cholesterol and low-density-lipoprotein-containing cholesterol between the patients and controls. After adjustments for age, education, BMI, and menopausal status, triglycerides remained significantly and positively associated with breast cancer risk. The significant correlation between the high levels of triglycerides and breast cancer risk (odds ratio = 5.12) may be attributed to differences in lipid metabolism between the women with breast cancer and controls, or to the consequences of breast cancer.
