【摘要】 目的:对36例采用新辅助化疗的骨肉瘤患者进行回顾性分析。方法:36例骨肉瘤患者均采用新辅助化疗。第1周期AP方案:用法ADM60mg/m2、DDP120mg/m2;第2、3周期大剂量MTX方案:MTX200mg/kg或8g/m2(成人),12g/m2(儿童);第4周期IFO方案:IFO2g/m2,连用5天,每一周期间隔10～15天,4个周期为1疗程;术前化疗2个疗程,术后化疗3～4个疗程。结果:采用新辅助化疗的36例患者中,最终保肢率为(30/36)83.3%,1～3年生存率(36/36)100%,4年生存率(26/36)72.2%,5年生存率(20/36)55.6%,随访率100%。结论:新辅助化疗不仅可以提高骨肉瘤患者的生存率,尚可增加保肢手术成功率,提高患者的生存质量。更多还原
