Aberrant growth factor receptor signaling can augment or suppress estrogen receptor (ER) function in hormone-dependent breast cancer cells and lead to escape from anti-estrogen therapy. Interruption of HER2/ER cross-talk with lapatinib can restore sensitivity to anti-estrogens and thus, should be investigated in combination with endocrine therapy in patients with ER+/HER2-negative breast cancers.
异常的生长因子受体信号可以增强或抑制激素依赖性乳腺癌细胞中的雌激素受体 (ER) 功能,并导致逃避抗雌激素治疗。用拉帕替尼阻断 HER2/ER 交叉对话可以恢复对抗雌激素药物的敏感性,因此,应在 ER+/HER2-阴性乳腺癌患者中与内分泌治疗联合进行研究。
