近10年来,分子靶向药物用于肿瘤治疗取得突破性进展。与传统放化疗的不同在于,分子靶向治疗作用在肿瘤细胞的特定分子上,而这些分子在正常的细胞几乎不表达。因此具有很好的特异性,识别并杀伤一些微小病灶中的肿瘤细胞,且对正常细胞伤害较小。据报道国内外已有十多种药物被批准用于临床肿瘤治疗。然而临床试验验证,分子靶向治疗药物如小分 In the past 10 years, molecular targeted drugs have made breakthrough progress in cancer treatment. The difference with traditional radiotherapy and chemotherapy is that molecular targeted therapy acts on specific molecules of tumor cells, and these molecules are hardly expressed in normal cells. Therefore has a very good specificity, identify and kill some tumor cells in the lesion, and less damage to normal cells. It is reported that more than a dozen drugs have been approved for clinical oncology treatment at home and abroad. However, clinical trials verify that molecular targeted therapies such as small points
