目前我国乳腺癌的发病率逐年上升,为女性最常见的恶性肿瘤之一,且发病年龄亦呈年轻化趋势,严重威胁女性健康。手术联合放疗、化疗、内分泌治疗及靶向药物治疗的综合治疗是乳腺癌的主要治疗手段,其中术后放疗是其治疗的重要组成部分,主要采用最经典的传统常规分割放疗模式。随着放射生物学研究的不断深入以及放疗技术的飞速发展,大分割放疗模式亦被更多地应用于临床,随之对大分割放疗模式的安全性及有效性方面的关注也越来越多。
At present, the incidence of breast cancer in our country is increasing year by year, which is one of the most common malignant tumors in women. The incidence of breast cancer also shows a younger tendency and threatens the health of women. Surgery combined with radiotherapy, chemotherapy, endocrine therapy and targeted drug therapy is the main treatment of breast cancer, including postoperative radiotherapy is an important part of its treatment, the main use of the most classic conventional radiotherapy mode. With the further research of radiobiology and the rapid development of radiotherapy, the large fractionated radiotherapy model has also been applied more and more in clinical practice, and more and more attention has been paid to the safety and effectiveness of the large fractionated radiotherapy model .
