    • The present invention provides methods for improving the treatment effect of a chemotherapy regimen of a patient suffering from breast cancer, in particular locally advanced, recurrent or metastatic HER-2 negative breast cancer, by adding bevacizumab (Avastin®) to a chemotherapy regimen by determining the expression level, in particular the blood plasma expression level, of one or more of VEGFA, VEGFR2 and PLGF relative to control levels of patients diagnosed with breast cancer, in particular locally advanced, recurrent or metastatic HER-2 negative breast cancer. In particular, the present invention provides methods of improving the treatment effect, wherein the treatment effect is the progression-free survival of the patient. The present invention further provides for methods for assessing the sensitivity or responsiveness of a patient to bevacizumab (Avastin®) in combination with a chemotherapy regimen, by determining the expression level, in particular the blood plasma expression level, of one or more of VEGFA, VEGFR2 and PLGF relative to control levels in patients diagnosed with breast cancer, in particular locally advanced, recurrent or metastatic HER-2 negative breast cancer.
    • 本发明提供了通过将化疗方案加入贝伐珠单抗(Avastin?)来改善患有乳腺癌,特别是局部晚期,复发或转移性HER-2阴性乳腺癌的患者化疗方案的治疗效果的方法, 相对于诊断为乳腺癌,特别是局部晚期,复发或转移性HER-2阴性乳腺癌的患者的对照水平,VEGFA,VEGFR2和PLGF中的一种或多种的表达水平,特别是血浆表达水平。 特别地,本发明提供了改善治疗效果的方法,其中治疗效果是患者的无进展生存期。 本发明进一步提供了通过确定VEGFA的一种或多种的表达水平,特别是血浆表达水平来评估患者与贝伐珠单抗(Avastin?)联合化疗方案的敏感性或反应性的方法, VEGFR2和PLGF相对于诊断为乳腺癌,特别是局部晚期,复发或转移性HER-2阴性乳腺癌的患者的对照水平。
