白血病的治疗方案

ID: ANH19228chis
医疗动画文字记录:你或你关心的人可能被诊断出患有白血病。这段视频将帮助你了解一些可采用的治疗方案。白血病是一种起源于正在生成的血细胞的癌症,通常是白细胞。在白血病中,骨髓中的造血细胞会产生许多不能正常工作的恶性白细胞。这会削弱免疫系统功能。医生会专门为你制定治疗方案。方案将基于白血病的类型、症状、年龄、整体健康状况和其他因素。治疗方案可能包括以下一种或多种:化疗、放疗、靶向治疗、免疫治疗、干细胞移植。化疗使用药物通过血液循环杀死快速生长的细胞,比如癌细胞。另一种治疗方法是放疗。它使用辐射杀死癌细胞或阻止它们生长。根据白血病的分期和类型不同,放射的目标区域也不同。治疗白血病的放疗是体外照射。它使用一台机器,将辐射从体外瞄准癌症。靶向治疗使用针对癌细胞的特定靶点或标记物的药物。由于癌细胞可能比正常细胞有更多的这些标记,靶向治疗可能会比正常细胞更多地影响癌细胞。当靶向治疗药物附着在癌细胞的标记物上时,癌细胞可能会停止生长和分裂。免疫疗法可以帮助免疫系统对抗白血病。例如,单克隆抗体是实验室生产的免疫系统用来对抗细菌、病毒、化学物质和其他外来物质的蛋白质。单克隆抗体可以被设计成附着在白血病细胞的标记物上,并成为攻击白血病细胞的免疫系统的一部分。当单克隆抗体附着在免疫细胞上时,可以帮助识别和摧毁白血病细胞。干细胞移植用自己或健康供者的干细胞替代在癌症治疗过程中受损或被破坏的造血细胞。首先,从你或捐赠者身上收集健康的干细胞。然后,当你接受癌症治疗(如化疗或放疗,杀死所有血细胞)时,干细胞被储存起来。在完成这些治疗后,就能够提供给你健康的干细胞。在身体里,这些干细胞为未来的血细胞提供健康的供给。医生可能会开出我们讨论过的治疗方法的组合,或者与以上不同的治疗方案。当你被诊断为白血病时,请保持与医生和癌症护理团队交流。
