前情提要
仅仅时隔34天，正值国际圆周率日、爱因斯坦生日、霍金忌日、白色情人节之际，美国国家综合癌症网络（NCCN）于美国东部时间2019年3月14日悄然将《乳腺癌临床实践指南》更新至2019年第1版，全文仍为215页，免费注册后可免费下载：
NCCN为非国立、非营利、全国综合癌症中心联盟组织，1993年11月正式成立，1995年1月31日宣布成为全国联盟，其总部于2018年9月28日由宾夕法尼亚州华盛顿堡迁至普利茅斯米庭，由最初13个至目前28个美国知名综合癌症中心组成：
关于本版（2019年第1版）NCCN乳腺癌临床实践指南，其架构仍为临床路径＋循证解读＋参考文献，其依据仍来自权威学术期刊最新发表的III期大样本多中心随机对照研究结果，更新较多，具体如下：
小叶原位癌（LCIS-1）
由于2018年1月1日开始正式执行的美国癌症联合委员会（AJCC）癌症分期手册第8版TNM分期已将小叶原位癌删除，故将本页从NCCN乳腺癌临床实践指南删除；参见NCCN乳腺癌筛查诊断指南。
General: Recommendations for Lobular Carcinoma in Situ (LCIS-1) were removed from the NCCN Guidelines for Breast Cancer; see the NCCN Guidelines for Breast Cancer Screening and Diagnosis.
导管原位癌的诊断、检查、基本治疗（DCIS-1）
修改：若患者遗传性乳腺癌风险高则进行遗传咨询 → 若患者有遗传性乳腺癌风险则进行遗传咨询（亦适用于BINV-1、BINV-11、BINV-18、IBC-1）
Modified bullet: Genetic counseling if patient is at high risk for hereditary breast cancer. (also applies to BINV-3, -11, and -18)
新增：淋巴结不手术的乳房肿块切除术＋乳房局部加速放疗（ABPI）作为基本治疗选择之一
Added Lumpectomy without lymph node surgery + accelerated partial breast irradiation (APBI) as an option for primary therapy.
修改脚注j：乳房肿块切除术后全乳放疗可将DCIS复发率减少大约50%。复发大约一半为浸润癌、一半为DCIS。若干因素决定了局部复发风险：肿块可触及、肿块较大、分级较高、切缘接近或阳性、年龄<50岁。如果患者和医师认为个体风险“低”，那么某些患者可以仅仅接受切除治疗。评估三种局部治疗的数据表明患者生存相似 → 选择可能适合APBI的低风险DCIS患者，低风险DCIS的定义来自RTOG9804研究，包括DCIS由筛查检出、细胞核分级低至中级、肿瘤大小≤2.5厘米、手术阴性切缘>3毫米。
Modified footnote j: Whole-breast radiation therapy following lumpectomy reduces recurrence rates in DCIS by about 50%. Approximately half of the recurrences are invasive and half are DCIS. A number of factors determine local recurrence risk: palpable mass, larger size, higher grade, close or involved margins, and age <50 years. If the patient and physician view the individual risk as "low," some patients may be treated by excision alone. Data evaluating the three local treatments show no differences in patient survival. Select patients with low-risk DCIS may be considered suitable for APBI if they meet all aspects of the definition of low-risk DCIS from the RTOG 9804 trial, including screen-detected DCIS, low to intermediate nuclear grade, tumor size ≤2.5 cm and surgical resection with margins negative at >3 mm.

删除以下内容，移至乳腺浸润癌的术前全身治疗原则（BINV-M）：对于可能无法进行保乳手术但是需要化疗的患者，术前全身治疗仍然是可以接受的选择。这对于术前全身治疗有效患者（T2-3 N1 M0、T3 N0-1 M0）避免腋窝淋巴结清扫可能有益。参见ST-1。
Removed the following bullet from this page, it is included in the Principles of Preoperative Systemic Therapy (BINV-M): "In cases where breast-conserving surgery may not be possible but patient will need chemotherapy, preoperative systemic treatment remains an acceptable option. This may be of benefit for patients who may be able to avoid ALND with a good response to therapy (T2N1M0, T3N0M0, T3N1M0). See ST-1"

乳腺浸润癌：生育与节育（BINV-C）
修改：随机对照研究表明，对于雌激素受体阴性肿瘤乳腺肿瘤（无论激素受体状态如何）绝经前女性，辅助化疗期间给予促性腺激素释放激素（GnRH）激动剂治疗进行卵巢抑制，可以保护卵巢功能，并且减少化疗所致闭经的可能性。

乳腺浸润癌：内分泌辅助治疗（BINV-K）
修改脚注b：权衡卵巢抑制治疗相关风险和获益的讨论至关重要。根据SOFT和TEXT临床研究结局，对于复发风险较高（即年轻、肿瘤分级高、淋巴结受累）的绝经前女性，应该考虑芳香酶抑制剂或他莫昔芬5年＋卵巢抑制。删除：2014年《新英格兰医学杂志》参考文献，因为2018年《新英格兰医学杂志》已经发表SOFT和TEXT两项研究中位随访8年的生存结局。
Modified footnote: A balanced discussion of the risks and benefits associated with ovarian suppression therapy is critical. Aromatase inhibitor or tamoxifen for 5 y plus ovarian suppression should be considered, based on SOFT and TEXT clinical trial outcomes, for premenopausal women at higher risk of recurrence (ie, young age, high-grade tumor, lymph node involvement). Pagani, NEJM 2014, Prudence, NEJM 2014). Survival data are still pending.
修改脚注c：专家组认为三种选择性芳香酶抑制剂（即阿那曲唑、来曲唑、依西美坦）术后辅助和术前新辅助随机对照研究表明，抗肿瘤效果和毒性反应特征相似。芳香酶抑制剂辅助治疗的最佳持续时间尚不确定。
Modified footnote: The panel believes The three selective aromatase inhibitors (ie, anastrozole, letrozole, exemestane) have shown similar anti-tumor efficacy and toxicity profiles in randomized studies in the adjuvant and preoperative settings. The optimal duration of aromatase inhibitors in adjuvant therapy is uncertain.

乳腺浸润癌：术前全身治疗原则（BINV-M）
修改：一些研究表明，接受术前全身治疗的患者与接受术后辅助全身治疗的患者相比，术前化疗后局部和淋巴引流区域复发的风险增加，该局部和淋巴引流区域复发风险增加的原因在于术前治疗患者的最终局部治疗方法不合理。这些被纳入分析的研究所用化疗方案并不标准、未包括靶向治疗、并未采用现代影像学技术、有些使用了不标准的局部和淋巴引流区域管理方法。应该注意遵循BINV-12和BINV-15概述的方法，以确保合理的局部和淋巴引流区域管理。
Modified bullet: Some studies suggest have reported an increased risk of locoregional recurrence in patients receiving preoperative systemic therapy compared with those receiving postoperative adjuvant systemic therapy. This increased risk of locoregional relapse has been attributed to suboptimal delivery of definitive local therapy in patients treated in the preoperative setting. following use of preoperative chemotherapy. The trials analyzed used chemotherapy regimens that are no longer standard, did not include targeted therapies, and did not use modern imaging techniques, and some used non-standard locoregional management. Care should be taken to follow the procedures outlined in BINV-12 and BINV-15 to assure appropriate locoregional management.
术前全身治疗已知获益，新增：允许残留病变的HER2阳性和三阴性乳腺癌患者调整或加入辅助治疗方案。

Modified footnote: CDK4/6 inhibitor (abemaciclib, palbociclib, or ribociclib) in combination with an aromatase inhibitor (anastrozole, letrozole, or exemestane) or fulvestrant may be considered as a treatment option for first-line therapy for women who are postmenopausal or premenopausal (receiving ovarian suppression or ablation with an LHRH agonist) with hormone-receptor positive, HER2-negative metastatic breast cancer. Fulvestrant has been combined with CDK4/6 inhibitors (ie, palbociclib, ribociclib) in the first-line setting in two randomized trials.
新增脚注：如果治疗以化疗＋曲妥珠单抗＋帕妥珠单抗开始，并且化疗停止，内分泌治疗可以加入曲妥珠单抗＋帕妥珠单抗。

修改脚注：无足够的安全数据推荐紫杉类常规用于妊娠期间。不过，如果根据疾病状态，如有临床指征，妊娠前三个月后紫杉醇每周给药可被接受。妊娠期间禁用抗HER2疗法。
Modified footnote: There are insufficient safety data to recommend general use of taxanes during pregnancy. However, the use of paclitaxel weekly administration after the first trimester is acceptable if clinically indicated by disease status. The use of anti- HER2 therapy is contraindicated during pregnancy.
新增脚注：如果妊娠前三个月后，可以考虑妊娠中期进行术前化疗。
New footnote: If late 1st trimester, may consider preoperative chemotherapy in the 2nd trimester.
