Abstract

Radiotherapy (RT) after breast-conserving surgery for breast cancer (BC) has been shown to reduce local recurrence rates and mortality. The conventional treatment of postoperative radiotherapy was 50 to 50.4 Gy, administered in 25 to 28 fractions over a period of 5 to 6 weeks. In the last 20 years, there is clinical evidence to consider hypofractionated treatment regimens safe and effective. Moderate hypofractionation, administered over 3 weeks, can be considered the standard of care after conservative surgery or mastectomy, as well as in irradiation of lymph node areas, with similar results regarding local control and survival and with effects on acute and chronic normal tissue. , similar or smaller. Ultrahypofractionated treatment, administered in 5 sessions, for 1 or 5 weeks, is a safe and effective treatment after conservative surgery and mastectomy without reconstruction. Early results have been reported that ultrahypofractionated treatment in 1 week is safe when lymph node areas are irradiated.

乳腺癌的标准照射分数是多少?

乳腺癌保乳手术后放射治疗(RT)已被证明可以降低局部复发率和死亡率。术后常规放疗为50 ~ 50.4 Gy，分25 ~ 28次放疗，疗程5 ~ 6周。在过去的20年里，有临床证据表明低分割治疗方案是安全有效的。在保守手术或乳房切除术后进行3周以上的中度低分割治疗，以及在淋巴结区域的放射治疗，在局部控制和生存方面具有相似的结果，对急性和慢性正常组织都有影响。类似的或更小的。超低分割治疗是保守手术和乳房切除术后安全有效的治疗方法，分5个疗程，持续1或5周。早期的研究结果表明，当淋巴结区域接受放疗时，1周内的超微分割治疗是安全的。
