BACKGROUND AND PURPOSE No evidence has been presented until now whether recommendations given in recently issued guidelines concerning CIED-bearing patients significantly decrease RT-related complications. MATERIALS AND METHODS 160 RT-cases were prospectively treated with 3D-CRT, IMRT, SBRT using exclusively 6 MV photons (n = 146) and electrons (n = 14) according to the 2015 issued German DEGRO/DGK-guideline for CIED-bearing patients and compared to 40 RT-cases (3D-CRT, 10-23 MV photons (n = 39) and electrons (n = 1)) of CIED-bearing patients which were treated in concordance to the 1994 issued AAPM-guideline. RESULTS With AAPM-recommendations, complications occurred in 7/39 (17.95%) photon-RT cases, one patient experienced inadequate defibrillation therapy. For all patients treated with photon energies between 6 and 23 MV, a relative risk for CIED failure if treated with > 6 MV was calculated to be 9.03 (95% CI 5.24-15.55). After implementation of the DEGRO/DGK guideline, no complications were noted in 147 cases treated with photons, even though CIED-doses were as high as 5.37 Gy. In 13 cases treated with electrons, one PM lost patient-related data in a patient receiving antiproliferative RT to mammary glands. CONCLUSIONS Implementation of the German DEGRO/DGK-guideline effectively prevented radiation-associated CIED failures in patients treated with photons. Limitation of photon energy to 6 MV, suspension of defibrillation therapy in ICDs, surveillance of patients according to risk stratification and avoidance of direct irradiation of CIEDs should become standard of care.

德国 DEGRO/DGK 指南对 CIED 患者放疗的有效性和适用性

背景和目的 直到现在,还没有证据表明最近发布的关于 CIED 患者的指南中给出的建议是否能显着降低放疗相关并发症。材料和方法 根据 2015 年发布的德国 DEGRO/DGK 承载 CIED 指南,160 例 RT 病例接受 3D-CRT、IMRT、SBRT 前瞻性治疗,仅使用 6 MV 光子(n = 146)和电子(n = 14)患者并与根据 1994 年发布的 AAPM 指南治疗的 CIED 患者的 40 例 RT 病例(3D-CRT,10-23 MV 光子(n = 39)和电子(n = 1))进行比较。结果 根据 AAPM 建议,7/39 (17.95%) 光子放疗病例发生并发症,一名患者经历了不充分的除颤治疗。对于所有接受 6 至 23 MV 光子能量治疗的患者,如果用 > 6 MV 治疗,CIED 失败的相对风险计算为 9.03(95% CI 5.24-15.55)。实施 DEGRO/DGK 指南后,尽管 CIED 剂量高达 5.37 Gy,但在 147 例接受光子治疗的病例中未发现并发症。在 13 例接受电子治疗的病例中,一名 PM 丢失了一名接受乳腺抗增殖放疗的患者的患者相关数据。结论 德国 DEGRO/DGK 指南的实施有效地预防了光子治疗患者与辐射相关的 CIED 失败。将光子能量限制为 6 MV、暂停 ICD 的除颤治疗、根据风险分层监测患者以及避免 CIED 的直接照射应成为标准护理。实施 DEGRO/DGK 指南后,尽管 CIED 剂量高达 5.37 Gy,但在 147 例接受光子治疗的病例中未发现并发症。在 13 例接受电子治疗的病例中,一名 PM 丢失了一名接受乳腺抗增殖放疗的患者的患者相关数据。结论 德国 DEGRO/DGK 指南的实施有效地预防了光子治疗患者与辐射相关的 CIED 失败。将光子能量限制为 6 MV、暂停 ICD 的除颤治疗、根据风险分层监测患者以及避免 CIED 的直接照射应成为标准护理。实施 DEGRO/DGK 指南后,尽管 CIED 剂量高达 5.37 Gy,但在 147 例接受光子治疗的病例中未发现并发症。在 13 例接受电子治疗的病例中,一名 PM 丢失了一名接受乳腺抗增殖放疗的患者的患者相关数据。结论 德国 DEGRO/DGK 指南的实施有效地预防了光子治疗患者与辐射相关的 CIED 失败。将光子能量限制为 6 MV、暂停 ICD 的除颤治疗、根据风险分层监测患者以及避免 CIED 的直接照射应成为标准护理。一位 PM 丢失了一位接受乳腺抗增殖放疗的患者的患者相关数据。结论 德国 DEGRO/DGK 指南的实施有效地预防了光子治疗患者与辐射相关的 CIED 失败。将光子能量限制为 6 MV、暂停 ICD 的除颤治疗、根据风险分层监测患者以及避免 CIED 的直接照射应成为标准护理。一位 PM 丢失了一位接受乳腺抗增殖放疗的患者的患者相关数据。结论 德国 DEGRO/DGK 指南的实施有效地预防了光子治疗患者与辐射相关的 CIED 失败。将光子能量限制为 6 MV、暂停 ICD 的除颤治疗、根据风险分层监测患者以及避免 CIED 的直接照射应成为标准护理。
