现行早期乳腺癌保乳术后的常规切线野放射治疗技术存在靶区内剂量不均匀的缺陷.国内外多位研究者将调强放疗(IMRT)应用于保乳术后患者,以期在提高靶区剂量均匀性、降低危及器官受量及改善美容效果方面体现出一定优势.

The current challenge from radiotherapy of early breast cancer has been to minimize the morbidity caused by this treatment without losing efficacy.Conventional two-dimensional radiotherapy breast plans can produce substantial dose inhomogeneities.Intensity-modulated radiotherapy(IMRT) can be used to improve the dose homogeneity in an irradiated volume.And to some extent,IMRT can reduce radiation doses to adjacent normal tissues including the contralateral breast,heart and lung,and improve the cosmetic outcome.
