In 2010, the ACOSOG Z0011 trial showed equivalent survival and recurrence between sentinel lymph node biopsy (SLNB) alone versus axillary lymph node dissection (ALND) for those with a tumor positive sentinel node (SN). We examined national trends in axillary surgery following neoadjuvant chemotherapy (NAC) for clinically node positive disease in the years prior to and after the Z0011 trial publication. 12,063 women with cT1-4N1M0 invasive breast cancer who underwent NAC from 2006 to 2013 and had 1-3 positive nodes on pathology were selected from the National Cancer Data Base...

INTRODUCTION: International guidelines differ regarding their recommendations on axillary treatment of patients with non-visualized sentinel lymph nodes (non-vSLN). Therefore, we distributed a survey among Dutch oncological surgeons to determine their routine practice and opinion regarding axillary treatment in case of a non-vSLN, with the emphasis on whether these practices and opinions have changed since publication of the Z0011 trial. METHODS: A Dutch nationwide survey containing 10 questions regarding clinical routine during the sentinel node procedure and axillary treatment of non-vSLN patients was distributed among 510 oncological surgeons...

BACKGROUND: Axillary staging (pN) is considered one of the most important prognostic factors in breast cancer patients. However, the Z0011 study data drastically reduced the number of surgical axillary dissections in a selected group of patients, limiting the prognostic information relating to axillary involvement to the sentinel lymph node (SLN). It is known that there is a relationship between SLN total tumour load (TTL) and axillary involvement. The objective of this study is to analyse the relationship between the TTL and outcomes in patients with early stage breast cancer...

Purpose: The American College of Surgeons Oncology Group (ACOSOG) Z0011 trial reported that complete dissection of axillary lymph nodes (ALNs) may not be warranted in women with clinical T1-T2 tumors and one or two involved ALNs who were undergoing lumpectomy plus radiation followed by systemic therapy. The present study was conducted to identify preoperative imaging predictors of ≥3 ALNs. Materials and Methods: The training set consisted of 1917 patients with clinical T1-T2 and node negative invasive breast cancer...

INTRODUCTION: Intraoperative touch imprint cytology (TIC) of the sentinel lymph node(s) (SLN(s)) in the treatment of breast cancer has significantly reduced the number of axillary block dissections (ABD) required during second surgeries. Based on recent studies, ABD was not considered necessary if the presence of tumor cells/micrometastasis was confirmed in the SLN(s) or in the case of macrometastases in a patient group meeting the inclusion criteria for the ACOSOG Z0011 study. Our aim was to determine the sensitivity and usefulness of TIC with regard to these results...

The purpose of our study was to quantitate the changes in axillary lymph node dissection (ALND), frozen section (FS), and the impact on costs after the publication of the American College of Surgeons Oncology Group (ACOSOG) Z0011 trial. We compared axillary nodal management and cost data in breast cancer patients who met Z0011 criteria and were treated with lumpectomy and sentinel lymph nodes (SLN) biopsy from 2007 to July 2013. Of 800 patients, 67 (13.5%) and 34 (12.5%) patients in the pre- and post-Z0011 era had 1-2 positive SLN...

OBJECTIVE: To evaluate the role of preoperative axillary staging with ultrasound (US) and fine needle aspiration cytology (FNAC). Can we avoid intraoperative sentinel lymph node (SLN) examination, with an acceptable revision rate by preoperative staging? DESIGN: This study is based on the retrospective data of 336 patients that underwent US evaluation of the axilla as part of their staging. A FNAC biopsy was performed when abnormal lymph nodes were visualized. Patients with normal appearing nodes on US or a benign diagnostic biopsy had removal of the SLNs without intraoperative pathological examination...

Axillary ultrasound is increasingly utilized for nodal staging preoperatively in patients presenting with invasive breast cancer to provide guidance for preoperative chemotherapy or proceeding directly to surgery. Improvements in ultrasound technology make it possible to assess the nodal burden in order to identify those patients not eligible for ACOSOG Z0011 management. However, its ability to detect metastasis is variable and dependent on operator's skills, size of metastatic deposit, and primary tumor histology subtype...

The one-step nucleic acid amplification (OSNA) assay was initially developed for the intraoperative assessment of sentinel lymph node metastases in breast cancer. This assay measures cytokeratin 19 (CK19) mRNA copy number and is widely used in hospitals. The results of the IBCSG 23-01, ACOSOG Z0011, and AMAROS trials demonstrated that no further axillary dissection is required for patients with sentinel lymph nodes that tested positive for cancer, which has led to a decreasing trend in the need for intraoperative assessment of lymph nodes...

BACKGROUND AND OBJECTIVE: The early results of the American College of Surgeons Oncology Group (ACOSOG) Z0011 trial demonstrated no difference in locoregional recurrence for patients with positive sentinel lymph nodes (SLNs) randomized either to axillary lymph node dissection (ALND) or sentinel lymph node dissection (SLND) alone. We now report long-term locoregional recurrence results. METHODS: ACOSOG Z0011 prospectively examined overall survival of patients with SLN metastases undergoing breast-conserving therapy randomized to undergo ALND after SLND or no further axillary specific treatment...

Pathologists typically examine the sentinel lymph nodes excised from patients with invasive breast cancer more thoroughly than they have historically those from axillary lymph node clearance specimens. This, it is thought, increases the chances of detecting small metastatic foci (i.e. macrometastases (>2 mm), micrometastases (0.2-2 mm), or isolated tumour cell clusters (<0.2 mm or <200 cancer cells in one section)). However, the clinical significance of these small metastatic deposits remains unclear...

BACKGROUND: Axillary dissection (AD) was historically recommended for all patients with breast tumor involvement discovered by sentinel lymph node biopsy (+SLNB). However, after the ACOSOG Z0011 trial, omission of AD became the recommendation for selected patients with a +SLNB. We report the impact of ACOSOG Z0011 on the completion AD rate in patients with +SLNB at our institution. METHODS: We retrospectively reviewed all patients diagnosed with breast cancer between March 2009 and February 2013 (n = 1781)...

RANDOMIZED CONTROLLED TRIAL

Sentinel lymph node biopsy alone is the current surgical axillary treatment for early-stage breast cancer patients with a negative sentinel lymph node (SLN). The possibility to omit axillary dissection also in presence of positive SLNs has been promoted by the American College of Surgeons Oncology Group (ASOCOG) Z0011 randomized trial. Several limitations and evidences of potential selection bias made this trial fairly controversial. Stronger evidence than currently available is needed on the safety of foregoing axillary dissection in well-defined populations of patients with positive SLNs...

OBJECTIVES: To evaluate use of sentinel lymph node (SLN) frozen section (FS) before and after publication of the Z0011 trial. METHODS: We identified 116 pre-Z0011 and 134 post-Z0011 patients from 18 months before and after Z0011-initiated changes. Clinicopathologic features were assessed by chart review. RESULTS: Post-Z0011 SLN FS use markedly declined when performed with breast-conserving therapy (BCT) (P < .0001), with SLN FS in 53 (73...

INTRODUCTION: Evidence from the American College of Surgeons Oncology Group (ACOSOG) Z0011 trial suggests completion axillary lymph node dissection (cALND) after positive sentinel lymph node biopsy (+SLNB) does not improve outcomes in select patients, leading to practice variation. A multidisciplinary group of surgeons, oncologists, and pathologists developed a regional guideline for cALND which was disseminated in August 2012. We assessed the impact of Z0011 and the regional guideline on cALND rates...

BACKGROUND: The ACOSOG Z0011 trial, a randomized controlled trial among patients with sentinel node positive breast cancer treated with breast conserving therapy, concluded that axillary lymph node dissection (ALND) can be omitted in these patients. However, questions were raised on the general applicability if the results of the Z0011 trial. Therefore, the aim of this study was to assess the practice changing effect of the Z0011 trial by quantifying the proportion of all node positive breast cancer patients who meet the inclusion criteria which are based on the Z0011 trial, thus in whom an ALND could be omitted...

BACKGROUND: The American College of Surgeons Oncology Group Z0011 trial demonstrated the safety of omitting axillary lymph node dissection (ALND) for women with fewer than three positive sentinel lymph nodes (SLNs) who are undergoing breast-conservation therapy (BCT). Because most of the women were postmenopausal with estrogen receptor (ER) positive cancers, applicability of ALND for younger patients and those with triple-negative (TN) or human epidermal growth factor receptor 2 (HER2) overexpressing (HER2+) tumors remains controversial...

PURPOSE: Various prediction models have been developed to predict the risk of having no additional axillary metastases in patients with a positive sentinel lymph node biopsy (SLNB), thereby disregarding patients with a positive ultrasound-guided lymph node biopsy (UGLNB). However, in the post-Z0011 trial era it is important to identify all patients with extensive nodal involvement for whom axillary treatment might still be beneficial. Therefore, the aim of this study is to identify factors predicting extensive nodal involvement (≥3 positive nodes) in the axilla, with the emphasis on the method of axillary staging: node positivity by UGLNB versus SLNB...
