Drug resistance is a common clinical problem in cancer treatment. The overexpression of P-glycoprotein appears to be closely associated with multi-drug resistance to anticancer agents. YB-1 binds to the Y-box in the promoter region of MDR1, which encodes P-glycoprotein. We evaluated the correlation between nuclear YB-1 and P-glycoprotein expression and other molecules, such as hormonal receptors, angiogenic factors, immune factors, and methalloprotease in 63 human breast cancers. Nuclear YB-1 expression had a significant correlation with P-glycoprotein and PgR expression, and also with CD68 grade, concerning accumulation of tumor associated macrophages. This series did not demonstrate P-glycoprotein and nuclear YB-1 expression might be one of the useful prognostic marker of breast cancer. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved.
