The effect of sampling site and closeness of malignant tumor on the retinoid, carotenoid, tocopherol, and tocotrienol concentration of adipose tissue of human breast was studied in 10 cases of breast cancer. The four anatomic quadrants of breast did not differ from each other statistically significantly in relation to adipose tissue concentrations of the vitamins studied. Proximity of malignant tumor did not affect the vitamin concentrations when compared to the more distant sampling sites. Representative sample of breast adipose tissue for vitamin concentration analysis can be obtained from tissue adjacent to the tumor.
在10例乳腺癌患者中，研究了采样部位和恶性肿瘤的距离对人乳腺脂肪组织中类视黄醇、类胡萝卜素、生育酚和生育三烯酚浓度的影响。乳腺的四个解剖象限在所研究维生素的脂肪组织浓度方面，统计学上无显著差异。与距离较远的采样部位相比，恶性肿瘤的距离并不影响维生素浓度。用于维生素浓度分析的乳腺脂肪组织代表性样本可从肿瘤附近的组织获取。
