摘要 目的:探讨优化医用直线加速器高能X线全身照射(total body irradiation,TBI)的技术对造血干细胞移植后发生间质性肺炎(IP)的影响。方法:28例患者接受以环磷酰胺(CY)+全身放疗±依托泊苷(Vp-16)为预处理方案的造血干细胞移植,TBI采用分割放疗、肺挡铅技术,其中19例患者采用热释光剂量片(TLD)监测全身放疗的肺吸收剂量,TBI总量12Gy,共6次,肺部剂量8.5Gy。结果:28例患者随访24~104个月,中位随访时间75个月,5年总生存率(OS)为(53.6±9.4)%,5年无复发生存(RFS)(71.1±8.6)%;19例接受热释光剂量片监测吸收剂量的患者,肺吸收中位剂量8.44Gy,脐部吸收中位剂量11.87Gy,全身剂量的不均匀性<±10%;28例患者无1例发生IP。结论:采用分割全身放疗、肺挡铅、并用热释光剂量片监测肺吸收剂量可降低IP的发生。 OBJECTIVE:To investigate the effect of modified technique of total body irradiation (TBI) with high energy X-ray of accelerator on interstitial pneumonia after hematopoietic stem cell transplantation(HSCT). METHODS:Twenty-eight consecutive patients received HSCT. All the patients received CY+TBI±Vp-16 as conditioning regimen. The combination of fractionated TBI and lung blocks were used in all 28 patients to minimize IP as TBI techniques (TBI total dose to 12 Gy, 2 Gy twice a day for 3 days,lung dose to 8.5...
