ABSTRACT
<p><b>OBJECTIVE</b>To investigate the predictive value of HER-2 and ER expression for chemosensitivity of taxane in the treatment of advanced breast cancer.</p><p><b>METHODS</b>Of 268 advanced breast cancer patients treated 71 were by paclitaxel alone, 32 by docetaxel alone, 110 by paclitaxel combined with anthracylines or gemcitabine or platins and 55 by docetaxel-based combinations. HER-2 and ER expression of all patients treated by taxane underwent immunohistochemical (IHC) assay.</p><p><b>RESULTS</b>Univariate analysis showed the response rate (RR) in HER-2 overexpression group was 56.7%, and in HER-2 weak expression group 33.3% (P = 0.003). The response rate in ER positive group and ER negative group was 33.3% and 48.9%, respectively, with a significant difference (P = 0.015). The RR was 67.6% in ER negative but HER-2 overexpression group. However, in ER positive but HER-2 weak expression group and the other groups, the RR were around 35% (P < 0. 01). Multivariate analysis showed that overexpression of HER-2 was the only significant factor to predict the chemosensitivity of taxane (P = 0. 007), but the ER, Karnofsky performance score (KPS), anthracylines, metastatic sites were not the statistically significant chemo-sensitivity predictive factors for taxane.</p><p><b>CONCLUSION</b>ER negative and/or HER-2 overexpression, especially latter, may be associated with good response in advanced breast cancers treated by taxane.</p>
