本文探讨术后放射治疗对于乳腺癌治疗的价值。作者指出,近来对乳腺癌的治疗方法存在广泛争论。其中争论最大的问题是对有腋窝淋巴结受累的乳腺癌患者行术后常规放疗是否有益?乳腺癌的生物学行为与其它大多数癌一样,在只有局部淋巴结转移而无全身扩散时,可行局部根治,包括术后放疗,辅助化疗及内分泌治疗以予防病灶扩散。术后放疗的临床试验结果不一。癌症研究运动工作会的实验表明,Ⅰ期或Ⅱ期患者行术后常规放疗对10年生存率没有意义,他们报告Ⅱ期患者局部复发率高达45%。Host 等在五年中使用~((?)9)Co 治疗有淋巴结 This article discusses the value of postoperative radiotherapy for the treatment of breast cancer. The authors point out that there has been widespread debate over the treatment of breast cancer. One of the most controversial issues is whether it is beneficial to postoperative conventional radiotherapy for breast cancer patients with axillary lymph node involvement. The biological behavior of breast cancer, like most other cancers, is feasible when there is only local lymph node metastasis without systemic spread. , Including postoperative radiotherapy, adjuvant chemotherapy and endocrine therapy to prevent spread of lesions. Clinical trials of postoperative radiotherapy have varied. The experiments conducted by the Cancer Research Sports Working Party showed that conventional radiotherapy for patients with stage I or II had no significance for 10-year survival rate. They reported that the local recurrence rate of stage II patients was as high as 45%. Host et al. use ~((?)9)Co to treat lymph nodes in five years
