表皮生长因子受体(epidermal growth factor receptor, EGFR)基因状态是表皮生长因子受体酪氨酸激酶抑制剂(epidermal growth factor receptor tyrosine kinase inhibitor, EGFR-TKI)疗效的预测因素,但其对化疗疗效的预测作用尚不明确。本研究旨在探讨对晚期非小细胞肺癌(non-small cell lung cancer, NSCLC)患者一线化疗疗效的预测意义。. This evidence concerns the gene EGFR and non-small cell lung carcinoma.
