目的总结乳腺癌诊治指南中关于单纯乳腺原位癌相关章节的内容。方法采用文献复习的方法,对有关单纯乳腺原位癌的指南及文献加以综述。结果通过复习中国抗癌协会《乳腺癌诊治指南与规范》、美国家综合癌症网络(National Comprehensive Cancer Network,NCCN)指南、《St.Gallen共识》、欧洲肿瘸瘤医。学会(European Societyfor Medical Oncology,ESMO)的《临床实践指南》、日本的《乳腺癌外科指南》等最常用的临床实践指南后发现,手术治疗仍然是目前一单纯乳腺原位癌的主要治疗手段段大多数指南建议,如果系单纯乳腺原位癌不用进行腋窝下手术,只有在不排除存在浸润性导管癌或因为解剖部位的原因致手术切除一可能影响后续的前哨淋巴结活检时才同期进行前哨淋巴结活检。保乳手术后应该接受放疗,雌激素受体阳性的保乳手术患者可以接受内分泌治疗,对于已经行全乳切除术者需要权衡用药的利弊。结论虽然单纯的乳腺原位癌预后较浸润性癌更好,但相关的研究远较浸润性癌少,各种指南的推荐诊治方案也存在一定差异,仍需要一步深入研究才能得出公认的诊治方案。 Objective To summarize the relevant chapters of breast cancer in situ cancer in the guideline for diagnosis and treatment of breast cancer. Methods The literature review method was used to review the guidelines and literature on breast cancer in situ. The results were reviewed through the review of the Chinese Cancer Society’s “Guidelines and Guidelines for the Diagnosis and Treatment of Breast Cancer”, the National Comprehensive Cancer Network (NCCN) Guidelines, the “St. Gallen Consensus,” and the European Society of Tumors. The most commonly used clinical practice guidelines, such as the European Society for Medical Oncology (ESMO) Guide to Clinical Practice and Japan’s Guide to Breast Cancer Surgery, found that surgical treatment is still the main treatment method for breast cancer in situ. Most guidelines recommend that sentinel lymph nodes be performed at the same time if a simple breast cancer in situ does not require an axillary surgery, but only if an invasive ductal carcinoma is not ruled out or because an anatomical site causes surgical resection, which may affect the subsequent sentinel lymph node biopsy. Biopsy. Breast-conserving surgery should be followed by radiotherapy. Patients with estrogen receptor-positive breast-conserving surgery can receive endocrine therapy. For those who have undergone total mastectomy, they need to weigh the pros and cons. Conclusion Although the prognosis of breast cancer in situ is better than that of invasive cancer, the related research is far less than that of invasive cancer. There are certain differences in the recommended diagnosis and treatment plans for various guidelines. It still needs a further study to arrive at a universal diagnosis and treatment. Program.
