【摘要】 目的:观察雌激素受体(ER)不同表达对局部晚期乳腺癌TC新辅助化疗方案的敏感性。方法:采用免疫组化EnVision法,检测57例局部晚期乳腺癌患者化疗前ER的表达情况,比较ER(-)病例与ER(+)病例对TC化疗方案的敏感性。结果:ER阴性组的敏感性为86.36%(19/22),ER阳性组的敏感性为60.00%(21/35),2组比较差异有统计学意义(P<0.05),说明ER(-)的乳腺癌患者对TC新辅助化疗方案更敏感。结论:ER(-)可作为局部晚期乳腺癌选用TC新辅助化疗方案的敏感性依据之一。更多还原

【Abstract】 OBJECTIVE:To observe the association between the ER expression and the sensitivity of TC chemotherapy in locally advanced breast cancer patients.METHODS:The expression of ER in 57 locally advanced breast cancer patients was detected by EnVision method,and the sensitivity to TC chemotherapy in ER negative(-)vs.ER positive(+)patients were evaluated.RESULTS:There were significant differences between the ER negative(-)patients and the ER positive(+)patients in the sensitivity to TC chemotherapy(86.36%(19/22)vs.60.00%(21/35))(P<0.05),demonstrating the higher sensitivity of ER negative(-)breast cancer patients to TC neoadjuvant chemotherapy.CONCLUSION:ER negative(-)may serve as a sensitivity marker to TC neoadjuvant chemotherapy in locally advanced breast cancer patients.更多还原
