甲磺酸阿帕替尼在局部进展期结直肠癌中的疗效和安全性

甲磺酸阿帕替尼在局部进展期结直肠癌中的疗效和安全性摘要

目的：探讨甲磺酸阿帕替尼在局部进展期结直肠癌中的疗效和安全性。

方法：从PubMed、Embase、WebofScience、CochraneCentral等数据库中检索了2000年1月至2021年3月相关的临床研究，共纳入10篇.

结果：综合分析10篇文章，甲磺酸阿帕替尼在局部进展期结直肠癌中的总有效率为62.5%~82.1%，其中完全缓解率为0~28.6%。总体来看，甲磺酸阿帕替尼的安全性良好，最常见的不良反应是高血压、口干、腹泻、皮疹等轻度不良反应；严重的不良反应较少见，主要包括肝功能损害、实质性脑病综合征、血栓等。

结论：甲磺酸阿帕替尼可作为局部进展期结直肠癌的有效治疗选择之一，具有较好的安全性，但需注意其不良反应。在临床应用中应根据患者病情和个体差异进行个体化治疗。
