Abstract
BACKGROUND Any advantage of performing targeted axillary dissection (TAD) compared to sentinel lymph node (SLN) biopsy (SLNB) is under debate in clinically node-positive (cN+) patients diagnosed with breast cancer. Our objective was to assess the feasibility of the removal of the clipped node (RCN) with TAD or without imaging-guided localisation by SLNB to reduce the residual axillary disease in completion axillary lymph node dissection (cALND) in cN+ breast cancer. METHODS A combined analysis of two prospective cohorts, including 253 patients who underwent SLNB with/without TAD and with/without ALND following NAC, was performed. Finally, 222 patients (cT1-3N1/ycN0M0) with a clipped lymph node that was radiologically visible were analyzed. RESULTS Overall, the clipped node was successfully identified in 246 patients (97.2%) by imaging. Of 222 patients, the clipped lymph nodes were non-SLNs in 44 patients (19.8%). Of patients in cohort B (n=129) with TAD, the clipped node was successfully removed by preoperative image-guided localisation, or the clipped lymph node was removed as the SLN as detected on preoperative SPECT-CT. Among patients with ypSLN(+) (n=109), no significant difference was found in non-SLN positivity at cALND between patients with TAD and RCN (41.7% vs. 46.9%, p=0.581). In the subgroup with TAD with axillary lymph node dissection (ALND; n=60), however, patients with a lymph node (LN) ratio (LNR) less than 50% and one metastatic LN in the TAD specimen were found to have significantly decreased non-SLN positivity compared to others (27.6% vs. 54.8%, p=0.032, and 22.2% vs. 50%, p=0.046). CONCLUSIONS TAD by imaging-guided localisation is feasible with excellent identification rates of the clipped node. This approach has also been found to reduce the additional non-SLN positivity rate to encourage omitting ALND in patients with a low metastatic burden undergoing TAD.

Abstract
The management of axillary lymph nodes in breast cancer is continually evolving. Recent data now support omitting axillary lymph node dissection (ALND) in most patients with metastases in up to two sentinel lymph nodes (SLNs) during upfront surgery and those with residual isolated tumor cells after neoadjuvant chemotherapy (NACT). In the upfront surgery setting, ALND is still indicated, however, in patients with clinically node-positive breast cancer or more than two positive SLNs and, after NACT, in case of residual micrometastases and macrometastases. Omission of the sentinel lymph node biopsy (SLNB) can be considered in many postmenopausal patients with small luminal breast cancer, particularly when axillary ultrasound is negative. Several randomized controlled trials (RCTs) are currently aiming at eliminating the remaining indications for ALND and also establishing omission of SLNB in a broader patient population. The movement to deescalate axillary staging is in part because of the association between ALND and lymphedema, which is swelling of an extremity because of lymphatic damage and obstructed lymphatic drainage. To reduce the risk of developing this condition, patients undergoing ALND can undergo reverse mapping of the axilla and immediate reconstruction or bypass of the lymphatics from the involved extremity. Decongestion and compression are the foundation of conservative treatment for established lymphedema, while lymphovenous bypass and lymph node transfer are surgical procedures to address the physiologic dysfunction. Radiotherapy is an essential component of breast locoregional therapy: more than three decades of radiation research has optimized treatment according to patient's risk of local recurrence while substantially reducing the number of treatment visits. High-quality RCTs have shown the efficacy and safety of hypofractionation-more than 2Gy radiation dose per treatment (fraction)-significantly reducing the burden of radiotherapy treatment for many patients with breast cancer. In 2024, guidelines recommend no more than 15-16 fractions for whole-breast and nodal radiotherapy, with some recommending five fractions for whole-breast radiotherapy. In addition, simultaneous integrated boost (SIB) has been shown to be noninferior to sequential boost with regards to ipsilateral breast tumor recurrence with similar or reduced long-term side effects, also reducing overall treatment length. Further RCTs are underway investigating other indications for five fractions, including SIB and regional node irradiation, such that, in future, it may be possible for the majority of breast radiotherapy patients to be treated with a 1-week course. This manuscript serves to outline the latest updates on axillary surgical staging, lymphatic surgery, and evidence-based radiotherapy in the treatment of breast cancer.

Clipping a Positive Lymph Node Improves Accuracy of Nodal Staging After Neoadjuvant Chemotherapy for Breast Cancer Patients, but Does It Drive Management Changes? Ann Surg Oncol 2024; 31:3186-3193. [PMID: 38427160 DOI: 10.1245/s10434-024-15052-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Accepted: 01/29/2024] [Indexed: 03/02/2024]
Abstract
BACKGROUND Sentinel lymph node (SLN) biopsy for cN+ breast cancer patients after neoadjuvant chemotherapy (NAC) is controversial because the false-negative rate (FNR) is high. Identification of three or more SLNs with a dual tracer improves these results, and inclusion of a clipped lymph node (CLN) (targeted axillary dissection [TAD]) may be even more effective. METHODS A retrospective, single-institution analysis of consecutive cN+ patients undergoing NAC from 2019 to 2021 was performed. Patients routinely underwent placement of a clip in the positive lymph node before NAC, and TAD was performed after completion of therapy. RESULTS The study analyzed 73 patients, and the identification rate for CLN was 98.6% (72/73). A complete response in the lymph nodes was achieved for 43 (59%) of the 73 patients. Overall, the CLN was not a SLN in 18 (25%) of 73 cases, and for women who had one or two and those who had three or more SLNs identified, this occurred in 11 (32%) and 7 (21%) of 34 cases, respectively. Failure of SLN or TAD to identify a positive residual lymph node status after NAC occurred in 10 (15%) of 69 and 2 (3%) of 73 cases, respectively (p = 0.01). In four cases, a SLN was not retrieved (5.5%), and two of these cases had a positive CLN. In three cases, the CLN was the only positive node and did not match with a SLN, directing lymphadenectomy and oncologic management change in two cases. Therefore, 7 (10%) of 73 cases had a change in surgical or oncologic management with TAD. CONCLUSIONS For a conservative axillary treatment in this setting, TAD is an effective method. It is more accurate than SLN alone and allows management changes. Further studies are warranted.

Abstract
Objective This study aimed to examine the axillary pathological condition through the development of an assessment framework for hormone receptor-positive breast cancer subsequent to neoadjuvant chemotherapy (NAC). Furthermore, the primary objective of this study was to examine the association between axillary status and breast tumors that are positive for hormone receptors following neoadjuvant chemotherapy. Methodology The present retrospective investigation encompassed a cohort including 300 individuals who were administered neoadjuvant chemotherapy before receiving surgical intervention. The data collection period for this study was from September 2021 to December 2022. All patients received neoadjuvant chemotherapy, per the guidelines established by the National Comprehensive Cancer Network (NCCN). We divided patients into two distinct groups: a test set of 250 patients and a validity set of 50 patients. Patients with no evidence of lymphoid involvement underwent a biopsy of sentinel lymph nodes (SLNB) and would have undergone axillary dissection if the biopsy results had indicated positive findings. A logistic regression analysis was employed to investigate the variables linked to the presence of residual positive axillary lymph nodes in the test set. Subsequently, a multivariate analysis was conducted on the variables that exhibited a p-value below 0.2 in the univariate study. In addition, a value of 1 was assigned to all risk factors to construct a comprehensive correlation prediction model. Results The participants included in this study had a mean age and body mass index (BMI) of 46.24 ± 9.1 years and 25.8 ± 2.5 kg, respectively. The present investigation examined the presence of pathological axillary metastases in a cohort of 188 patients, which accounted for 62.55% of the total sample, by utilizing core-needle biopsy. Furthermore, the incidence rates of individuals presenting with clinical T1 were reported as 14.6%, while 55.2% cases of T2, 17.8% cases of T3, and 13% cases of T4 tumors were reported, respectively. Of the overall occurrences, the prevailing histological subtype was invasive ductal carcinoma, accounting for 91.4% (222 out of 243) of the cases. Multiple criteria were identified as independent predictors of the presence of residual positive axillary lymph nodes. The factors under consideration encompass lymphovascular invasion (odds ratio= 7.108; 95% breast cancer stage (odd ratio = 5.025; 95%, HER2 negativity (odd ratio= 2.997), low Ki-67 expression (odd ratio = 4.231), and suspected positive axillary lymph nodes before surgical intervention. Conclusion The present study presents a novel prediction model that integrates imaging and pathology data, aiming to assist patients and healthcare practitioners in evaluating the efficacy of NAC for hormone-receptor-positive breast tumors. The model holds particular significance for individuals who exhibit clinical positivity in their lymph nodes (LNs). Consequently, the model has the potential to provide guidance for the management of axillary lymph nodes and prevent unnecessary dissection.

Abstract
Pathologic complete response (pCR) after Primary Systemic Treatment (PST) for breast cancer is associated with excellent long-term outcomes. With increasing use of PST, the indication for regional nodal irradiation (RNI) has been challenged. The aim of this paper is to review the literature on de-escalation of RNI in patients treated with PST. We found no level 1 evidence on de-escalation of RNI after PST, but several randomized trials are ongoing. Consequently, current de-escalation strategies are based on cohort studies. These studies showed that in patients with low nodal tumour burden (LNTB) (≤3 suspicious nodes at imaging) prior to PST, and ypN0 based on Axillary Lymph Node Dissection (ALND), omission of RNI resulted in very low regional recurrences (RR) without compromising survival. In patients with LNTB and ypN0 based on Sentinel Lymph Node Biopsy (SLNB), omission of axillary treatment also resulted in low RR; the majority of these patients received local radiotherapy. Similarly, in patients with ypN1 (ALND) disease, omission of RNI resulted in low 5-year RR rates. Low RR-rates were also found in the few studies replacing ALND by RNI, in patients with ypN1 (SLNB) disease. In patients with high nodal tumour burden prior to PST and ypN0 (SLNB), replacing ALND by RNI also resulted in low RR. Due to the limited number of patients, these data should be interpreted with caution. We conclude that although level 1 evidence is lacking, de-escalation of RNI after PST can be considered in selected cases.

Abstract
BACKGROUND Sentinel lymph node biopsy (SLNB) after neoadjuvant chemotherapy (NACT) in patients with breast cancer who are initially node-positive but convert to clinically/radiologically node-negative remains controversial. The primary aim was to assess pooled 5-year disease-free (DFS) and overall (OS) survival for patients who are initially node-positive but have a negative SLNB after NACT, and do not proceed to axillary lymph node dissection (ALND). METHODS The study was performed using PRISMA guidelines. A systematic literature search of relevant databases was conducted. The Der Simonian-Laird and Cochran-Mantel-Haenszel methods were used to calculate weighted pooled estimates for OS and DFS for this group compared with patients who had NACT and proceeded to ALND after a negative or positive SLNB. RESULTS Seven studies involving 915 patients who had a negative SLNB after NACT were included. Pooled estimates of 5-year DFS and OS in patients with a negative SLNB after NACT were 86 (95 per cent c.i. 82.1 to 90.3) and 93.1 (87.8 to 97.0) per cent respectively. Patients with a positive SLNB who underwent ALND had reduced 5-year DFS (OR 0.49, 95 per cent c.i. 0.35 to 0.69; P < 0.001) and OS (OR 0.41, 0.16 to 1.02; P = 0.06) compared with those who had a negative SLNB after NACT. There were no differences in DFS for patients who had a negative SLNB only compared with those undergoing ALND with a pCR (OR 1.65, 0.71 to 3.79; P = 0.24). CONCLUSION Patients who are initially node-positive and who achieve a complete clinical/radiological axillary response after NACT with a subsequent negative SLNB have high rates of DFS and OS after 5 years. Patients with residual disease have significantly reduced DFS and further axillary treatment may still be warranted.

Abstract
Objective To evaluate the efficiency and safety of sentinel lymph node biopsy (SLNB) in patients with breast cancer with complete response to neoadjuvant chemotherapy (NAC). Methods Ninety-two consecutive (T1-4 and N1-2) patients with breast cancer who had pathologic and/or clinical and radiologic axillary lymph node involvement were included. All patients received NAC. Patients with a clinical and radiologic complete response in the axilla after NAC underwent SLNB. Pathologic complete response (ypCR) was defined as the absence of residual invasive and in situ cancer, and near-complete response (ypNCR) represented in situ and/or ≤ 1 mm residual tumor in the breast and/or presence of malignant cell clusters (≤0.2 mm) and/or micrometastases (≤2.0 mm) in the axillary lymph nodes (ALN) (ypTis/T1mi, ypN0i+/pN1mi). Results The mean age of the 92 patients was 49.6 ± 10.3 years and the mean follow-up was 34.0 ± 17.8 months. With respect to breast tumors, 23 (25.0%) patients had complete and 14 (15.2%) had a near-complete response to NAC. Complete response in ALN was obtained in 39 (42.4%) patients and near-complete in six (6.5%) patients. The overall survival of the 33 patients who achieved ypCR and ypNCR was 100% and the remaining 59 patients with partial or no response to NAC was 83.1% at a mean follow-up of 34 months (p=0.063). Conclusions In this study, no event developed in cases with ypCR and ypNCR in the breast and axilla. The persistence of the same results in long-termfollow-ups may enable the use of ypNCR as a positive prognostic marker in addition to ypCR.

Abstract
Purpose To develop a scoring system for hormone receptor-positive (HR+) breast cancer patients who are expected to achieve axillary pathological complete response (pCR) after neoadjuvant chemotherapy (NAC). To confirm the correlation between axillary status and survival rate in HR+ breast cancer after NAC. Methods Women from the Shanghai Jiao Tong University Breast Cancer Database (SJTU-BCDB) who underwent NAC for cT1-4N1-3M0 primary HR+ breast cancer between 2009 and 2018 were included in the study. In this case, patient follow up was performed until 2022 for those with complete data before and after NAC. The main outcome measures were the axillary pCR rate, overall survival (OS), and disease-free survival (DFS). The patients were randomly assigned to a test set (n = 175) and a validation set (n = 68) in a 7 : 3 ratio. A prediction risk score was then developed based on the odds ratios from the multivariate analysis of the test set (n = 175) before being validated in the validation set (n = 68). Finally, the Kaplan-Meier curves were used to explore the survival on this score system. Results From the database, 243 women were included, and the median follow-up period was 47.5 months (95% confidence interval: 41.9-53.1). The axillary pCR rate was 18.9% (46 of 243), with the independent predictors of residual positive axillary lymph nodes (LNs) being lymphovascular invasion (LVI), breast conserving surgery (BCS), Ki67 < 14%, HER2 negativity, positive lymph nodes in ultrasound (US) before surgery, and stage III histological grade (All, P < 0.05). Using the above predictors of the model, the receiver operating characteristic (ROC) curve was used for calibration and inspection, with values for the test and validation sets being 0.847 (P < 0.001; 95% CI: 0.769, 0.925) and 0.813 (P < 0.001; 95% CI: 0.741, 0.885), respectively. The total risk score ranged from 0 to 6 for the multivariate analysis, and from this range, a risk score of 0-2 was defined as a low-risk group, while scores of 3-6 were defined as the high-risk one. By constructing the survival curve, it was found that the 5-year OS rates for the low-risk and high-risk groups were 89.0% and 84.2% (P = 0.236). Similarly, the 5-year DFS rates for the low-risk and high-risk groups were 80% and 68.5% (P = 0.048), respectively. In addition, axillary pathological stages were significantly correlated with the overall survival (OS) and disease-free survival (DFS) (All, P < 0.05). Conclusion The prediction model showed good performance for HR + breast cancer. LVI, BCS, low Ki-67, HER2 negativity, suspected positive LNs before surgery, and stage III histological grade were all risk factors for residual positive axillary LNs. However, unlike pathological stages, achieving pCR in the axillary LNs does not affect the survival status.

Axillary surgery after neoadjuvant therapy in initially node-positive breast cancer: international EUBREAST survey. Br J Surg 2022; 109:857-863. [PMID: 35766257 DOI: 10.1093/bjs/znac217] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 05/17/2022] [Accepted: 05/28/2022] [Indexed: 11/14/2022]
Abstract
BACKGROUND There is no consensus on axillary management after neoadjuvant therapy (NAT) in patients with clinically node-positive (cN+) breast cancer. To investigate current clinical practice, an international survey was conducted among breast surgeons and radiation oncologists. The aim of the first part of the survey was to provide a snapshot of international discrepancies regarding axillary surgery in this context. METHODS The European Breast Cancer Research Association of Surgical Trialists (EUBREAST) developed a web-based survey containing 39 questions describing clinical scenarios in the setting of axillary management in patients with cN1 disease converting to ycN0 after NAT. The survey was then distributed to breast surgeons and radiation oncologists via 14 breast cancer societies between April and October 2021. RESULTS Responses from 349 physicians in 45 countries were recorded. The most common post-NAT axillary surgery in patients with cN1 disease converting to ycN0 was targeted axillary dissection (54.2 per cent), followed by sentinel lymph node biopsy (SLNB) alone (20.9 per cent), level 1-2 axillary lymph node dissection (ALND) (18.4 per cent), level 1-3 ALND (4 per cent), and targeted lymph node biopsy (2.5 per cent). For SLNB alone, dual tracers were most commonly used (62.3 per cent). Management varied widely in patients with ambiguous axillary status before initiation of treatment or a residual metastatic burden in the axilla after NAT. In patients with ycN+ tumours, ALND was the preferred surgical approach for 66.8 per cent of respondents. CONCLUSION These results highlight the wide heterogeneity in surgical approaches to the axilla after NAT. To standardize the guidelines, further data from clinical research are urgently needed, which underlines the importance of the ongoing AXSANA (EUBREAST-3) study.

Lymph node staging after primary systemic therapy in women with breast cancer and lymph node involvement at diagnosis. Cir Esp 2022:S2173-5077(22)00158-2.

Abstract
OBJECTIVE The main objective of this study is to analyze the efficacy of combined axillary marking (lymph node clipping and sentinel lymph node biopsy (SLNB)) for axillary staging in patients with primary systemic treatment (PST) and pathologically confirmed node-positive breast cancer at diagnosis. The secondary objective is to determine the impact of lymph node marking in the suppression of axillary lymph node dissection (ALND) in the study group. METHODS We conducted a prospective study in which lymph node staging was performed using wire localization of positive lymph nodes and a SLNB with dual tracer. All patients who presented no metastatic involvement of the sentinel lymph node (SLN) or clip/wire-marked lymph node were spared an ALND. The multidisciplinary committee agreed on axillary treatment for patients with lymph node involvement. RESULTS Eighty one patients met the inclusion criteria. We identified and extirpated the clip/ wire-marked node in 80 of 81 patients (98.8%), with SLNB performed successfully in 88,9% of patients. The SLN and wire-marked node matched in 78.9% of patients; 76.2% of patients did not undergo ALND. CONCLUSIONS The combined axillary marking (clip and SLNB) in patients with metastatic lymph node at diagnosis and PST offers a high identification rate (98.8%) and a high correlation between the wire-marked lymph node and the SLN (78.9%). This procedure has enabled the suppression of ALND in 76.2% of patients.
