近年来发表的几个有关乳腺切除术后放射治疗的随机分组研究发现 ,放射治疗可以增加有高危因素患者的生存率 ,引起了人们对乳腺癌术后局部或区域放射治疗的更大关注。目前认为 ,对于早期患者 ,内乳淋巴结照射的价值并不明确。而对内象限和中央区病变、腋窝淋巴结阳性的患者 ,内乳淋巴结的术后放疗仍有争议。减少内乳区的照射范围 ,改进照射技术 ,可以减少心血管等系统的放射并发症。 In recent years, several published randomized researches on post-mastectomy radiotherapy found that radiation therapy can increase the survival rate of patients with high risk factors and cause more attention to the local or regional radiotherapy for postoperative breast cancer. Currently, the value of internal mammary lymph node irradiation is not clear for early stage patients. Intra-quadrant and central area lesions, axillary lymph node-positive patients, postoperative radiotherapy of breast lymph nodes is still controversial. Reduce the scope of the radiation within the milk area, improve the irradiation technology, can reduce cardiovascular system radiation complications.
