J Pers Med 2022; 12:jpm12091404. [PMID: 36143189 PMCID: PMC9505126 DOI: 10.3390/jpm12091404] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 08/22/2022] [Accepted: 08/26/2022] [Indexed: 11/16/2022] Open
Abstract
(1) Background: To establish similarities in the risk of axillary lymph node metastasis between different groups of women with breast cancer according to immunohistochemical (IHC) parameters. (2) Methods: Data was collected retrospectively, from 2000 to 2013, of 1058 node-positive breast tumours. All patients were divided according to the St Gallen 2013 criteria and IHC features. The proportion of axillary involvement (pN > pN0; pN > pN1mi; pN > pN1) was calculated for each group. Similarities in axillary nodal dissemination were explored by cluster analysis and association between IHC and risk of axillary disease was studied with multivariate analysis. (3) Results: Among clinico-pathological surrogates of intrinsic subtypes, axillary involvement was more frequent in Luminal-B like HER2 negative (45.8%) and less frequent in Luminal-B HER2 positive (33.8%; p = 0.044). Axillary macroscopic involvement was more frequent in Luminal-B like HER2 negative (37.9%) and HER2 positive (37.8%) and less frequent in Luminal-B HER2 positive (25.5%) and Luminal-A like (25.6%; p = 0.002). Axillary involvement ≥pN2 was significantly less frequent in Luminal-A like (7.4%; p < 0.001). Luminal-A with Luminal-B HER2 positive, and triple-negative with Erb-B2 overexpressing tumours were clustered together regarding any axillary involvement, macroscopic disease or ≥pN2. Among the defined subgroups, axillary metastases were more frequent when Ki67 was higher. In a multivariate analysis, Ki67>14% were associated with a risk of axillary metastases (HR: 1.31; 95% CI, 1.51−6.80; p < 0.037). (4) Conclusions: there are two lymphatic drainage pathways of the breast according to the expression of hormone receptor-related genes. Positive-ER tumors are associated with lower axillary involvement and negative-ER tumors and Ki67 > 14% with higher nodal involvement.

Predictive value of comb-push ultrasound shear elastography for the differentiation of reactive and metastatic axillary lymph nodes: A preliminary investigation. PLoS One 2020; 15:e0226994. [PMID: 31929558 PMCID: PMC6957145 DOI: 10.1371/journal.pone.0226994] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Accepted: 12/09/2019] [Indexed: 12/01/2022] Open
Abstract
Objectives To evaluate the predictive performance of comb-push ultrasound shear elastography for the differentiation of reactive and metastatic axillary lymph nodes. Methods From June 2014 through September 2018, 114 female volunteers (mean age 58.1±13.3 years; range 28–88 years) with enlarged axillary lymph nodes identified by palpation or clinical imaging were prospectively enrolled in the study. Mean, standard deviation and maximum shear wave elastography parameters from 117 lymph nodes were obtained and compared to fine needle aspiration biopsy results. Mann-Whitney U test and ROC curve analysis were performed. Results The axillary lymph nodes were classified as reactive or metastatic based on the fine needle aspiration outcomes. A statistically significant difference between reactive and metastatic axillary lymph nodes was observed based on comb-push ultrasound shear elastography (CUSE) results (p<0.0001) from mean and maximum elasticity values. Mean elasticity showed the best separation with a ROC analysis resulting in 90.5% sensitivity, 94.4% specificity, 0.97 area under the curve, 95% positive predictive value, and 89.5% negative predictive value with a 30.2-kPa threshold. Conclusions CUSE provided a quantifiable parameter that can be used for the assessment of enlarged axillary lymph nodes to differentiate between reactive and metastatic processes.

Abstract
Sentinel lymph node biopsy is now accepted as the initial approach for women with early stage breast cancer with clinically node-negative disease. We performed a pooled analysis of trials comparing axillary lymph node dissection to sentinel lymph node biopsy in patients with early stage breast cancer and pathologically negative sentinel lymph node analysis. A systematic MEDLINE review identified four randomized trials of axillary dissection versus sentinel lymph node biopsy in lymph node-negative early stage breast cancer patients. A meta-analysis was performed for survival and relapse. The combined analyses of these four trials found no significant difference in overall survival (relative risk [RR] 1.15; P=0.16; 95% CI: 0.95–1.39), breast cancer-specific (RR 1.03; P=0.85; 95% CI: 0.751.43) and disease-free survival (RR 1.07; P=0.3; 95% CI: 0.94–1.21), distant metastases (RR 1; P=0.98; 95% CI: 0.76–1.32), and ipsilateral breast recurrence (RR 1.64; P=0.34; 95% CI: 0.60–4.47) associated with sentinel lymph node biopsy. In particular, a similar rate of nodal recurrences was seen after sentinel lymph node biopsy (RR 1.74; P=0.13; 95% CI: 0.86–3.53). Axillary dissection does not confer a survival benefit nor prevent further nodal relapses in the setting of early stage, pathologically lymph node-negative breast cancer.

Abstract
The role of sentinel lymph node biopsy (SLNB) in pT1a and "microinvasive" breast cancer has not been extensively studied. We report our experience with SLNB in patients with "minimal" breast cancer to determine the incidence and type of SLN metastases, and to study the potential impact on their surgical or oncological management. Among some 3387 women operated upon for primary breast cancer who underwent sentinel lymph node biopsy at nine institutions participating in the Rome Breast Cancer Study Group, 251 were staged pT1a or pT1mic (7.4%). There were 13 cases of sentinel lymph node metastases identified in this group of patients (5.2%), seven macrometastases and six micrometastases. Additionally, ITC were diagnosed by immunohistochemistry in four cases (1.6%). The incidence of SLN metastases was 7/174 (4%) and 6/77 (7.8%) in patients with pT1a and pT1mic tumors, respectively (p=0.2). Age and histological grade were predictive factors for SLN metastases. Chemotherapy was seldom directed by axillary node status (8/38 patients). As the incidence of SLN metastases in these patients is very small, particularly in the pT1a group, the indications for even a minimally invasive procedure, such as sentinel lymph node biopsy, should be probably individualized.

Abstract
PURPOSE To review regional nodal (RN) management and identify predictors of RN relapse in patients treated with breast conserving surgery and radiation therapy (BCS+RT). METHODS AND MATERIALS Patients with Stage I and II breast cancer (N = 1920) underwent BCS+RT from 1973 to 2003. Patients undergoing RN were treated with a median dose of 46 Gy. Patients undergoing axillary dissection (AXD, N = 1330) were treated to the breast alone if node-negative (N = 984), and to the breast and supraclavicular fossa if node-positive (N = 346). Patients who did not undergo AXD (N = 590) were treated with RT to the supraclavicular fossa and axilla. Sentinel node biopsy (SNB) was performed on 126 patients. SN-negative patients (N = 110) were treated with tangents only. There were 16 SN-positive patients who did not undergo complete AXD and were treated with RT. RESULTS As of September 2005, there have been 36 RN relapses for an actuarial nodal control rate (NCR) of 98% at 10 years. There was no difference in NCR between those undergoing AXD (NCR = 97.4%) and those receiving RT without AXD (NCR = 97.9%). In multivariate analysis, young age, non-Caucasian race, and pathologic nodal status correlated with increased risk of nodal relapse. Of the 126 patients undergoing SNB, there was only 1 nodal recurrence. None of the 16 SN-positive patients treated with RT without AXD had nodal failure. CONCLUSIONS In patients undergoing BCS+RT, both regional nodal irradiation and AXD (including SNB) resulted in equally high rates of regional nodal control. Nodal RT may also be an effective treatment for SN-positive patients.

Abstract
OBJECTIVE Specify the role of axillary lymph node removal in micro-invasive in situ duct carcinomas (DCIS-MI) of the breast with a series of 107 consecutive cases. METHODS Single-centre, retrospective, anatomoclinical study with application of the European guidelines adopting as pathological definition the presence of areas of micro-invasion not exceeding 1mm. Axillary lymph node dissection was systematically complete and was preceded by the search for the sentinel node in 10 patients using the isotope method. RESULTS Lymph node invasion was revealed in 8 cases in the global population (7.5%). All the cases except one exhibited typical deleterious histological features: comedo architectural sub-type, high nuclear grade, and size of the lesion>3 cm. The lymph node invasion was of 18.5% in the sub-group of high-grade micro-invasive comedo-carcinomas measuring more than 3 cm. CONCLUSION Contrary to those exhibiting pure DCIS, DCIS-MI patients require surgical exploration of the armpit, the most appropriate modalities of which are currently debated: classical axillary lymph node dissection or search for the sentinel lymph node; the selective lymphadenectomy procedure is not yet a consensually validated technique.

Abstract
Identification of early-stage breast cancers has increased over the past 2 decades primarily because of mammographic screening. The general guidelines to management of breast cancer may not apply to the smallest of these tumors, as their metastatic potential may be smaller than larger tumors. Tumors < 5 mm (T1a) carry an excellent prognosis, despite a variety of treatment approaches. However, some patients' cancer returns. There appear to be some histologic features that can predict a higher risk of axillary metastases, and therefore, a higher risk of distant metastases. Controversy exists over the extent of treatment, as to whether less than conventional treatment, such as mastectomy, axillary evaluation, and breast-conserving surgery and radiation, can be done. T1a lesions associated with extensive ductal carcinoma in situ and T1a lesions in young patients should be treated with caution if less than conventional breast treatment is to be considered. In older patients with good histologic features, axillary assessment may not be necessary. Very wide excision alone may be appropriate for some patients, but partial breast irradiation is under study and may provide a reasonable compromise. Systemic therapy for node-negative patients is not recommended. Recurrences within the breast occur later in early-stage breast cancers than with extensive-stage breast cancers, requiring annual imaging and evaluation for many years.

Abstract
BACKGROUND Female Taiwanese breast cancer patients are younger than their Western counterparts. This study examined the predictors of axillary lymph node metastases in Taiwanese women with T1 breast cancer. METHODS Data from 394 Taiwanese women with T1 invasive breast carcinoma were retrospectively reviewed. RESULTS The data contained 6 T1a, 51 T1b, and 337 T1c breast tumors. The patients' ages ranged from 23 to 82 years (mean +/- SD, 48.2 +/- 11.4 years; median, 46.4 years). Axillary nodal metastases were present in 38.3% of the patients (16.7% in T1a, 35.3% in T1b, and 39.2% in T1c tumors). The patients with nodal metastases had significantly greater body weights and S-phase fractions than those without nodal metastases. Univariate analysis revealed that unfavorable pathology, lymphovascular invasion, S-phase fraction >7%, and nondiploid DNA ploidy were significantly associated with lymph node metastases. Lymphovascular invasion was the only significant variable as the independent predictor in the multiple logistic regression analysis. In the Cox proportional hazards regression analysis, axillary nodal status and lymphovascular invasion were significantly associated with survival. CONCLUSIONS Taiwanese women with small breast cancer displayed a relatively higher incidence of axillary lymph node metastases than Western women. Axillary lymph node dissection or sentinel lymph node biopsy should be conducted on Taiwanese patients with small invasive breast carcinomas, particularly when risk factors exist.

Abstract
Breast cancer is a heterogenous disease with significant variations in biologic potential, ranging from small, low-grade, DCIS discovered mammographically with essentially no impact on patient survival to rapidly growing, palpable, locally advanced invasive breast cancer with clinically palpable nodal metastasis. The current challenge is to identify the clinical, pathologic, and molecular factors that determine the biologic potential of a particular breast cancer. Although size, nodal status, histologic grade, age, surgical margin, and hormone receptor status of breast cancer are the most important prognostic factors, the focus of research must be beyond these factors to other nonspecific prognostic information. Bone marrow micrometastasis may be an important factor to help predict outcome (7a) and the complement of sentinel node biopsy, bone marrow analysis, and primary tumor features may allow physicians to better select therapy. With increased understanding of the individual molecular events that control the invasive potential of a particular cancer, practitioners should be better able to predict more accurately which patients have little risk of recurrent disease or metastasis and would be best served by surgery alone versus patients who have a high risk of recurrent and metastatic disease and who should receive multimodality care.

Abstract
AIMS The purpose of this study was to evaluate the feasibility of sentinel lymph-node biopsy in breast cancer patients at our institution and to compare the results of sentinel node (SN) biopsy to standard axillary lymph-node dissection (ALND). METHODS In a retrospective study the percentage of lymph-node positive patients and the number of micrometastases in 165 breast cancer patients following SN biopsy was compared to 195 patients who underwent ALND of level I and II without SN biopsy. The SN was identified using a combination of vital blue dye and a radiolabelled colloid. RESULTS Patients and tumour characteristics were comparable between both groups. SN biopsy found no significant difference in the number of node positive T1 cancer patients (SN group: 31/108 (28.7%) -- ALND group: 21/92 (22.8%)) and T2 tumours (SN group: 27/57 (47.4%) -- ALND group: 49/103 (47.6%)) between both groups. Micrometastases were more frequently found in the SN group when compared to the ALND group (six of 70 positive nodes) (P=0.04). CONCLUSION SN biopsy may be as accurate as standard axillary lymph-node dissection for the evaluation of the axillary lymph-node status in breast cancer patients.

Abstract
Axillary lymph node dissection (ALND) has traditionally been considered as a standard procedure in the surgical management of patients with breast cancer. The goals of ALND in breast cancer surgery are: (a) to provide accurate prognostic information, (b) to maintain local control of the disease in the axilla and (c) to provide a rational basis for decisions about adjuvant therapy. Although controversial, ALND may also be associated with a small therapeutic benefit. Recently, the question of whether ALND is needed for every patient with invasive breast cancer has been the subject of ongoing debate in the literature. This is mainly due to the widespread use of adjuvant systemic therapy for patients with node-negative breast cancer and to the increasingly frequent detection of small invasive cancers by mammographic screening; the majority of these patients have negative axillae. Sentinel lymph node (SLN) biopsy is a new, promising, minimally invasive procedure, which accurately predicts nodal status with minimal morbidity, and reserves ALND for patients with positive SLN biopsies. However, this method is still investigational. Partial (levels I and II) ALND remains the gold standard in the surgical management of patients with breast cancer.

Abstract
The utility of level I and II axillary lymph node dissection in women with primary tumors less than 1 cm in diameter has recently received extensive evaluation. Numerous patients undergo axillary lymph node dissection ultimately to discover no pathological involvement. This study investigates the lymph node status in T1 primary breast adenocarcinoma in our diverse patient population. A retrospective evaluation of patients treated at the Medical Center of Louisiana at New Orleans and the Tulane University Medical Center with breast adenocarcinoma less than or equal to 2 cm was performed. Demographic data and pathological reports were reviewed to obtain breast lesion size and lymph node status. One hundred sixteen patients were found to have T1 lesions. Ethnic distribution was African American 66 per cent; Caucasians 30 per cent; Hispanic 2 per cent; and Asian 3 per cent. Whereas no patients with T1a lesions had positive lymph nodes, 11 per cent of patients with T1b lesions and 36 per cent of patients with T1c lesions had positive lymph nodes. However, in our patient population no patients with tumors less than 1.0 cm. in diameter had positive lymph nodes. Although this may be due to our relatively small sample size axillary lymph node dissection may be unnecessary in this select patient population. For patients with lesions 1.0 cm and greater an axillary lymph node dissection seems to add necessary information for correct treatment in a small percentage of patients. The use of lymphatic mapping with sentinel axillary lymph node biopsy may reduce the number of unnecessary axillary dissections in early breast cancer.

Abstract
BACKGROUND Controversy continues to surround the best practice for management of the axilla in patients with early breast cancer (EBC), particularly the clinically negative axilla. The balance between therapeutic and staging roles of axillary surgery (with the consequent morbidity of the procedures utilized) has altered. This is due to the increasing frequency of women presenting with early stage disease, the more widespread utilization of adjuvant chemoendocrine therapy and, more recently, the advent of alternative staging procedures, principally sentinel node biopsy (SNB). The aim of the present review is to critically analyse the current literature concerning the preferred management of the axilla in early breast cancer and make evidence-based recommendations on current management. METHODS A review was undertaken of the English language medical literature, using MEDLINE database software and cross-referencing major articles on the subject, focusing on the last 10 years. The following combinations of key words have been searched: breast neoplasms, axilla, axillary dissection, survival, prognosis, and sentinel node biopsy. RESULTS Despite the trend to more frequent earlier stage diagnosis, levels I and II axillary dissection remain the treatment of choice in the majority of women with EBC and a clinically negative axilla. CONCLUSIONS Sentinel node biopsy has no proven superiority over axillary dissection because no randomized controlled trials have been completed to date. Despite this, SNB will become increasingly utilized due to encouraging results from major centres responsible for its development, and patient demand. Therefore if patients are not being enrolled in clinical trials strict quality controls need to be established at a local level before SNB is allowed to replace standard treatment of the axilla. Unless this is strictly adhered to there is a significant risk of an increase in the frequency of axillary relapse and possible increased understaging and resultant inadequate treatment of patients.

Abstract
BACKGROUND: A tumor 30 mm or less in diameter is a standard candidate for breast conserving surgery (BCS) in Japan. Axillary lymph node metastases (ALNM) is the most important prognostic factor for survival in patients with breast cancer, but the role of axillary node dissection has been controversial. Histopathological predictive factors of axillary lymph node involvement have not been established. The purpose of this study was to determine the association between the incidence of ALNM and histopathological factors by univariate and multivariate analysis METHODS: Sixty-five patients with noninvasive ductal carcinoma, and 993 patients with tumors 30 mm or less in diameter who underwent axillary dissection between 1988 and 1997 at our institute were reviewed. The association between ALNM and 13 histopathological factors (size, age, histological subtype, histological invasiveness, lymphatic invasion, vascular invasion, macroscopic classification, histological daughter mass, ductal spread, ER, PgR, p-53, and c-erbB-2) were analyzed by univariate and, when significant, by multivariate analysis. RESULTS: Only one patient with noninvasive ductal carcinoma had ALNM, and 33.1% of 993 patients with a tumor 30 mm or less in size had ALNM. Multivariate analysis identified six factors as independent predictors for ALNM: lymphatic invasion, size, histological invasiveness, macroscopic classification, age and histological daughter mass. CONCLUSION: Axillary lymph node dissection can be omitted in patients with noninvasive ductal carcinoma. Histopathological features of tumors 30 mm or less in diameter can be used to estimate the risk of ALNM, and routine axillary node dissection might be spared in selected patients at minimal risk of ALNM, if the treatment decision is not influenced by lymph node status, such as in elderly patients.

Abstract
The widespread use of mammography has resulted in the detection of an increasing number of small invasive breast cancers, i.e. those that are 1cm and smaller. Patients with these small cancers generally have a low incidence of axillary lymph node metastases, and this has led some to question the routine use of axillary dissection in these patients. In addition, the prognosis of these patients is generally favorable, and the routine use of adjuvant systemic therapy is difficult to justify. Nonetheless, some patients with these small invasive cancers will have axillary nodal involvement and/or develop metastatic disease. The identification of this prognostically unfavorable subset of patients within this otherwise favorable group is an important goal of clinical research. In this article, we review the available literature on prognostic factors for patients with breast cancers 1cm and smaller to help determine which of these features might be of value in the identification of patients at risk for axillary lymph node involvement and/or metastatic disease.

Abstract
Breast biopsy or mastectomy cases having diagnoses of carcinoma in situ with "microinvasion," "minimal invasion," "focal invasion," or "suggestive of invasion" were reviewed and all histologically identified foci of invasive disease from each case were measured using an ocular micrometer. Cases in which any single focus of invasion was greater than 5 mm or the added size of separate invasive foci exceeded 10 mm were excluded, resulting in a study group of 75 patients. Invasive neoplasm was present in the initial biopsy in 69 of 75 cases (92%); however, residual invasive neoplasm was found in the subsequent lumpectomy/mastectomy from 14 of these (20%). In 59% of cases, two or more histologically separate foci of invasion were identified. Invasive foci consisted of isolated cells or cell clusters, each less than 1 mm (microfocal invasion), in 33% of cases. In 12 cases, the sum of individual invasive foci was 5 to 10 mm. Axillary lymph nodes (LN) from 5 of 69 patients (7%) contained metastatic carcinoma (four cases, one LN positive; one case, two LN positive). The cumulative sizes of all invasive foci in the LN-positive group were microfocal invasion (one case), 0.6 mm (one case), 1.1 mm, 2.5 mm, and 5.8 mm. The difference in frequency of axillary node metastasis between tumors with microfocal and measurable invasion (4.3% v 8.6%) was not statistically significant. Follow-up data were available on 55 cases (mean interval, 66.1 months). One (node-negative) patient had duct carcinoma in situ recurrence in the same breast 4 years after initial treatment. Another (with unknown node status) developed an axillary lymph node metastasis 13 months after initial treatment (96% disease-free survival). We conclude that microscopic stromal invasion in breast carcinoma, at least in the setting of significant in situ component, is often initiated from multiple foci. Patients with microscopically invasive breast carcinoma have a small but significant risk of axillary metastases, although a highly favorable survival.

Abstract
Although it is generally accepted that axillary dissection provides no survival advantage in patients with breast cancer, it is commonly regarded as a reliable method of assessing nodal status and treating regional disease. However, it is time to consider eliminating routine axillary dissection in patients who are clinically node-negative. A sentinel lymph node biopsy may assess axillary nodal status while obviating a full axillary dissection. At present, axillary dissection remains the standard approach for the surgical management of all patients with invasive carcinoma of the breast, regardless of tumor size or patient age, though it is unnecessary for patients with small intraductal carcinomas.
