【摘要】 乳腺癌是女性常见的恶性肿瘤，而放射治疗作为乳腺癌综合治疗手段具有重要意义。乳腺癌术后辅助放射治疗可有效降低局部复发，提高患者生存率。但放射治疗的远期毒性，尤其是心脏毒性需要重点关注。指南主要包括国产创新一体化放射治疗设备治疗乳腺癌的诊疗常规和结合深吸气屏气(DIBH)技术的治疗。对于左侧乳腺癌患者，DIBH技术可达到降低心脏受照射剂量的目的。近年国内企业研发的创新一体化放射治疗设备，可与光学体表监测系统设备结合开展DIBH技术。在国家重点研发计划项目的支持下，中国医学装备协会放射治疗装备技术分会组织相关领域专家制定国产创新一体化放射治疗设备治疗乳腺癌的临床指南，旨在规范并推广国产创新一体化放射治疗设备及其DIBH技术在乳腺癌治疗中的临床应用。更多还原

【Abstract】 Breast cancer is the most prevalent malignant tumor in women. As a comprehensive treatment method, radiotherapy has crucial significance. Postoperative adjuvant radiotherapy can effectively reduce local recurrence, and improve patients’ survival. The long-term toxicities of radiotherapy, particularly cardiac toxicity, have become a critical concern because the treatment outcome of breast cancer is favorable and patients’ survival rate is high. For patients with left-sided breast cancer, the deep inspiration breath-hold(DIBH) technique can realize the aim that reduce the exposure dose on heart through using expansion effects of thoracic cavity and lung’s volume to increase the distance between heart and target area. In recent years, the innovatively integrated radiotherapy equipment, which were developed by domestic manufacturers, can combined with optical surface monitoring systems to develop DIBH technique. Therefore, the Radiotherapy Equipment and Technology Branch, China Association of Medical Equipment organized relative experts in the field to formulate clinical guideline of domestically innovative integrated radiotherapy equipment in treating breast cancer under the support of the National Key R&D Program of China, which aim is to standardize and promote the clinical application of domestically innovative integrated radiotherapy equipment and its DIBH technique in treating breast cancer.更多还原
