The aim of preoperative radiotherapy of mastocarcinoma is to reduce the size of the tumor to enable radical surgery in the third stage. This method is preferable to postoperative radiotherapy for anatomical and radiobiological reasons. It has not yet been possible to prove beyond doubt that preoperative radiotherapy also has a favourable effect on symptom-free survival. Curative radiotherapy without mastectomy is recommended for tumors of 2 - 3 cm size which are mobile, in small and medium-sized breasts, if the axilla is free or has only 1 - 2 mobile lymphatic nodes. Tumorectomy must be followed by surgical revision of the axillary region. High-voltage equipment is mandotory for radiotherapy. Results obtained to date are in no way inferior to those of mastectomy. Local control rate is 90-100%. The cosmetic result is usually excellent.
乳腺癌术前放疗的目的是缩小肿瘤大小，以便在第三阶段进行根治性手术。出于解剖学和放射生物学原因，这种方法优于术后放疗。目前尚无法确凿证明术前放疗对无病生存期也有积极影响。对于大小为2 - 3厘米、可活动、位于中小乳房且腋窝无转移或仅有1 - 2个可活动淋巴结的肿瘤，建议进行不切除乳房的根治性放疗。肿瘤切除术后必须对腋窝区域进行手术修正。放疗必须使用高压设备。迄今为止所获得的结果绝不亚于乳房切除术。局部控制率为90 - 100%。美容效果通常极佳。
