早期乳腺癌病人腋窝淋巴结处理的原则是在有效控制疾病的基础上追求精准与安全。因此,以腋窝放疗替代手术成为近年来的关注焦点。在未行新辅助治疗的人群中,腋窝淋巴结初诊阴性或保乳术后前哨淋巴结(SLN)微转移的病人无须追加腋窝淋巴结清扫(ALND)或完整的腋窝照射;保乳术后SLN 1~2枚宏转移可豁免ALND并行全乳或高切线野照射,SLN转移数目>2枚或SLN外淋巴结转移风险较高者,豁免ALND后需补充腋窝放疗;乳房切除术后SLN阳性病人中目前证据不足,如未行ALND可考虑补充腋窝放疗;在接受了新辅助全身治疗的病人中,如SLN转阴可豁免ALND并补充腋窝放疗,如SLN未转阴目前依然推荐行ALND。 相似文献

??Express and interpretation on American society of clinical oncology guideline update for Sentinel lymph node biopsy in early-stage breast cancer WU Ke-jin.
Department of General Surgery, Xinhua Hospital, Shanghai Jiaotong University School of Medicine, Shanghai 200092, China
Abstract 2014 April, American Society of Clinical Oncology (ASCO) issued new clinical practice guideline on sentinel lymph node biopsy for patients with early-stage breast cancer in Journal of Clinical Oncology (JCO). This guideline update reflects some changes since the 2005 guideline. Based on randomized clinical trials (RCTs), there are three recommendations: (1) Women without sentinel lymph node (SLN) metastases should not accept axillary lymph node dissection (ALND). (2) In most cases, Women with 1-2 metastatic SLNs going to undergo breast-conserving surgery (BCS) with whole-breast radiotherapy should not adopt ALND. (3) Women with SLN metastases planning to receive mastectomy should be provided ALND. Based on cohort studies and/or informal consensus, there are two prime recommendations. (1) Sentinel node biopsy (SNB) may be offered to those women with operable breast cancer and multicentric tumors, with ductal carcinoma in situ (DCIS) planning to undergo mastectomy, who previously got breast and/or axillary surgery or who accepted preoperative/neoadjuvant systemic therapy. (2) SNB should not be offered to those women with large or locally advanced invasive breast cancer (tumor size T3/T4), inflammatory breast cancer, or DCIS will undergo BCS, or are pregnant. 相似文献

Abstract Sentinel lymph node biopsy (SLNB) has been the primary care in clinically node negative breast cancer. Controversy still surrounds the SLNB of the internal mammary nodes. Because different kinds of tracer have respective feature, surgeons should choose the suitable tracer. All blue lymph nodes and any lymph nodes at the end of a blue lymphatic channel should be removed and designated as SLNs.Clinicians should not recommend ALND for women with early-stage breast cancer who have one or two SLN metastases and will receive breast-conserving surgery with conventionally fractionated whole-breast radiotherapy.Clinicians may offer ALND for women with early-stage breast cancer with nodal metastases found on SNB who will receive mastectomy. For patients who recieved neoadjuvant chemotherapy, SLNB after neoadjuvant chemotherapy is optimal. 相似文献

前哨淋巴结活检(SLNB)已成为腋窝淋巴结临床阴性早期乳腺癌的首选腋窝手术方式,但其适应证范围已有所扩大。内乳淋巴结是否需要SLNB,尚存争议。不同示踪剂有各自的特点,应用时需要根据各临床中心的实际情况予以选择。寻找前哨淋巴结(SLN)时,原则上要循着色淋巴管解剖至腋窝寻找SLN。对于符合美国外科医师协会肿瘤学组(ACOSOG)Z0011试验入组标准的存在1~2枚SLN转移的病例不需腋窝淋巴结清扫(ALND)。仅行全乳切除的病例,如果SLN阳性,则需要进行腋窝淋巴结清扫。对于接受新辅助治疗病人接受SLNB的时机,目前认为在新辅助治疗后进行为好。 相似文献

Background There is uncertainty about the utility of sentinel node biopsy (SNB) for ductal carcinoma in situ (DCIS) and its potential
to avoid axillary lymph node dissection (ALND) in patients undergoing mastectomy for DCIS.
Methods A review was conducted of 179 patients who underwent mastectomy with sentinel node biopsy for DCIS without invasion or microinvasion
on premastectomy pathology review.
Results The sentinel node identification rate was 98.9% (177/179). Twenty (11.3%) of 177 mastectomies for DCIS had a positive SNB:
two micrometastasis (pN1mi) and 18 isolated tumor cells [pN0(i+)]. Unsuspected invasive cancer was found in 20 (11.2%) of
179 mastectomies, eight T1mic, five T1a, three T1b, and four T1c tumors. Sentinel nodes were identified in 19 of 20 patients
with invasive cancer and four were positive: one pN1mi and three pN0(i+). Eighteen of 19 patients with unsuspected invasive
cancer were able to avoid axillary dissection on the basis of SNB results. Of the 159 patients whose final pathology revealed
DCIS without invasion, a sentinel node was identified in 158 (99.4%). The SNB was positive in 16 patients (10.1%): one pN1mi
and 15 pN0(i+). Three patients underwent ALND on the basis of positive SNBs and in each the SNB was the only positive node.
Conclusions 11% of patients undergoing mastectomy for DCIS were found to have invasive cancer on final pathology. The use of SNB during
mastectomy for DCIS allowed nearly all such patients to avoid axillary dissection. These results support routine use of SNB
during mastectomy for DCIS. 相似文献

前哨淋巴结活检(SLNB)替代腋窝淋巴结清扫(ALND)已成为临床腋窝淋巴结阴性早期乳腺癌病人的标准处理方式。有限腋窝淋巴结转移的病人,接受保乳治疗满足美国外科医师协会肿瘤学组(ACOSOG)Z0011、IBCSG 23-01入组条件,可豁免ALND;或参考AMAROS,考虑腋窝放疗替代ALND;接受乳房完全切除无放疗的病人,推荐ALND。区域淋巴结放疗能够降低乳腺癌局部区域复发,在早期乳腺癌病人的腋窝处理中应权衡临床病理指标进行个体化治疗。新辅助治疗初始临床腋窝淋巴结阴性的病人可在新辅助治疗后行SLNB。新辅助治疗前可疑腋窝淋巴结优选超声引导下穿刺明确状态并标记转移淋巴结。选择适宜病人,采用双示踪、活检超过2枚以上前哨淋巴结、评估标记的新辅助治疗前转移淋巴结,并考虑将淋巴结分期N0(i+)纳为进行ALND的标准,满足上述条件,则初始腋窝淋巴结有转移新辅助治疗后临床完全缓解的病人可谨慎考虑接受SLNB。实践中,除外参与相关临床试验,ALND仍是这部分病人的治疗推荐。 相似文献

Value of sentinel lymph node biopsy in breast ductal carcinoma in situ upstaged to invasive carcinoma 总被引:2,自引:0,他引:2

Abstract: The role of sentinel lymph node (SLN) biopsy in patients with initial diagnosis of ductal carcinoma in situ (DCIS) is still a dilemma. Different studies are trying to define predicting factors of invasive cancer in DCIS. The aim of this study was to confirm the value of SLN biopsy in DCIS because of the invasive upstaging risk on final histology. Patients with initial diagnosis of DCIS and with axillary SLN biopsy were selected. All diagnoses were confirmed by biopsy of mammographic lesions. Surgical treatment was lumpectomy or mastectomy associated with SLN biopsy. Imprint stains were performed, and then serial sections were stained with hematoxylin and eosin (H&E) and with immunohistochemistry (IHC). A complete axillary lymph node dissection (ALND) was performed during the same surgery when a node metastasis was found. Eighty patients were enrolled in the study. Of the 61 patients who were initially diagnosed with DCIS, 12 (20%) were upstaged to microinvasive or invasive carcinoma and 9 (15%) had a metastatic SLN. Patients upstaged to invasive carcinoma had macrometastatic SLN immediately fed by a complete ALND. SLN micrometastases and isolated cells were detected by IHC and secondary complete ALND found an additional metastatic lymph node in one patient. Tumor size larger than 30 mm and mastectomy were the only significative predicting factors of upstaged disease (p < 0.0001) in our study. In patients with initial diagnosis of large DCIS programmed for mastectomy, SLN biopsy should be discussed in order to detect underlying invasive disease and to spare patients a second operating time. 相似文献

Abstract Sentinel lymph node biopsy(SLNB) has replaced axillary lymph node dissection(ALND) to stage clinically node-negative breast cancer patients. In the patients with low-volume nodal metastasis, ALND could be safely avoided when treated with breast-conserving therapy eligible for Z0011 or IBCSG 23-01, or radiation considered referring to AMAROS. ALND is still recommended for patients with involved axillary nodes received mastectomy and not planned for radiation. Addition of regional nodal irradiation in subgroups of patients reduces locoregional recurrence significantly and should be recommended taken all clinical and pathologic factors considered for individual patients. For patients with clinically node-negative disease, SLNB following neoadjuvant therapy is considered an acceptable approach.Ultrasound-guided biopsy and localization of suspicious axillary lymph nodes before neoadjuvant therapy are preferred. SLNB may be an option after neoadjuvant therapy in patients with proven positive axillary nodes who achieved clinical complete response, given that usage double tracers, biopsy more than 2 sentinel lymph nodes, evaluation the labelled lymph node before neoadjuvant therapy, and stage N0 (i+) may be regarded as the criteria for ALND. ALND remains the standard-of-care for the subset of patients in clinical practice, unless enrolled on some clinical trials. Staying the current of axillary treatments in early-stage breast cancer helps to make wiser clinical decision and organize further in-depth research, so that safe, effective and moderate axillary treatments can be performed. 相似文献

Sentinel node biopsy in breast cancer 总被引:9,自引:0,他引:9
John M. Barnwell MD Mark A. Arredondo MD Daniel Kollmorgen MD John F. Gibbs MD Dominick Lamonica MD William Carson MD Paul Zhang MD Janet Winston MD Stephen B. Edge MD 《Annals of surgical oncology》1998,5(2):126-130
Background: Sentinel lymph node biopsy (SNB) in breast cancer may be used in place of axillary lymph node dissection (ALND) if SNB accurately
stages the axilla. This study assessed the success and accuracy of axillary SNB with isosulfan blue (ISB) and technetium-99
sulfur colloid (TSC) compared to ALND.
Methods: Forty-two women with T1 or T2 breast cancer underwent SNB and ALND. Sixty to 90 minutes before anesthetic induction, a mixture
of 3 mL ISB and 1 mCi TSC was injected around the primary cancer or prior biopsy site. Intraoperatively, the SLN was identified
using a gamma detector (Neoprobe 1000) or by visualization of the blue-stained lymph node and afferent lymphatics. The SLN
was excised separately, and a level I/II ALND was completed. The histologic findings of the axillary contents and SLN were
compared.
Results: An axillary SLN was found in 38 of 42 (90%) cases. SLN localization rate and predictive value were the same for women who
had and those who had not undergone excisional biopsy before the date of SNB. Fifteen of 42 (36%) patients had lymph node
metastases. The SLN was positive in all women with axillary metastases (negative predictive value, 100%).
Conclusions: If confirmed by larger series, a negative SNB may eliminate the need for ALND for select women with breast cancer.

What is the value of axillary dissection or sentinel node biopsy in patients with ductal carcinoma in situ? 总被引:1,自引:0,他引:1
BACKGROUND: Some surgeons have advocated sentinel node biopsy (SNB) for ductal carcinoma in situ (DCIS). The value of the information obtained is not clear. METHODS: From 1972 to 2005, 564 selected patients with pure DCIS had axillary staging with either SNB or axillary lymph node dissection (ALND). Data were collected in a prospective database. RESULTS: Only 2 of 564 patients had positive nodes by hematoxylin and eosin, and they were both in the ALND group. Both patients had mastectomies, were upstaged, received chemotherapy, and survived for more than 10 years without local or distant recurrence. Among 171 patients who had SNB, 10 had isolated tumor cells found by immunohistochemistry. Two patients who underwent SNB had local recurrence, neither developed distant or regional recurrence. Six of 564 patients in the ALND group developed local invasive recurrence and died of metastatic breast cancer, but none of them had positive nodes. CONCLUSIONS: Information from lymph node examination in DCIS patients failed to predict poor outcome. SNB is useful for DCIS in mastectomy, especially with immediate reconstruction. It may be indicated for DCIS at high risk for upgrading to invasive cancer on final excision, but reliable criteria for identifying these tumors are not yet available. 相似文献
