Abstract
BACKGROUND Sentinel lymph node biopsy in breast cancer is considered the standard of staging in cases of clinically negative lymph nodes. Its omission in favor of axillary dissection generates significant morbidity. OBJECTIVE To determine the total number of sentinel node biopsy procedures in breast cancer in Colombia from 2017 through 2020, model and analyze them as if they were performed only in stage I breast cancer patients, and integrate their results into the concepts of quality of medical care. METHODS Search in a database of the Ministry of Health and Social Protection of Colombia with sentinel lymph node biopsy codes, and filters of breast cancer and year. Their results are contrasted with the number of cases in stage I of breast cancer. RESULTS Breast cancer TNM staging was reported in 22154 cases, 3648 stage I. In the same time frame, the number of sentinel lymph node biopsies for breast cancer in Colombia was 1045, 28.64% of the total cases reported in stage I. CONCLUSIONS Colombia is far from complying with the standard indicator of sentinel lymph node biopsy. It is recommended to concentrate breast cancer cases in hospitals that provide the conditions for its performance.

Abstract
BACKGROUND Modern breast surgical oncology incorporates many aspects of care including preoperative workup, surgical management, and multidisciplinary collaboration to achieve favorable oncologic outcomes and high patient satisfaction. However, there is variability in surgical practice and outcomes. This review aims to identify modifiable surgeon factors influencing breast surgery outcomes and provide a definition of the modern breast surgical oncologist. METHODS A systematic literature search with additional backward citation searching was conducted. Studies describing modifiable surgeon factors with associated breast surgery outcomes such as rates of breast conservation, sentinel node biopsy, re-excision, complications, acceptable esthetic outcome, and disease-free and overall survival were included. Surgeon factors were categorized for qualitative analysis. RESULTS A total of 91 studies met inclusion criteria describing both modifiable surgeon factor and outcome data. Four key surgeon factors associated with improved breast surgery outcomes were identified: surgical volume (45 studies), use of oncoplastic techniques (41 studies), sub-specialization in breast surgery or surgical oncology (9 studies), and participation in professional development activities (5 studies). CONCLUSIONS On the basis of the literature review, the modern breast surgical oncologist has a moderate- to high-volume breast surgery practice, understands the use and application of oncoplastic breast surgery, engages in additional training opportunities, maintains memberships in relevant societies, and remains up to date on key literature. Surgeons practicing in breast surgical oncology can target these modifiable factors for professional development and quality improvement.

Comparison of survival outcomes between axillary conservation and axillary lymph node dissections in N1 early breast cancer: a propensity-matched SEER analysis. Clin Transl Oncol 2023; 25:1091-1101. [PMID: 36515887 PMCID: PMC10025184 DOI: 10.1007/s12094-022-03017-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 11/15/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND Sentinel lymph node dissection (SLND) is an alternative to axillary lymph node dissection (ALND) for breast cancer surgery. But the criteria of SLND only for patients with limited disease in the sentinel node is disputed. METHODS From the Surveillance, Epidemiology, and End Results (SEER) database, 2000-2015, we identified 97,296 early breast cancer females with 1-3 axillary lymph nodes macro-metastasis. Of them, 1-5 (axillary conservation group), 6-9, and ≥ 10 (ALND group) axillary lymph nodes were dissected in 28,639, 16,838, and 51,819 patients, respectively. According to the criteria of the ACOSOG Z0011 trial, two historical cohort studies of patients who underwent lumpectomy or mastectomy were conducted and the survival outcomes between ALND and axillary conservation were compared. RESULTS Overall, dissection of 6-9 regional lymph nodes resulted in the worst prognosis. After propensity-matched analysis, it was found that patients in the axillary conservation group had worse survival than the ALND group in overall survival. No significant difference in prognosis between the group undergoing lumpectomy was found both in OS and BCSS. Subgroup analysis revealed that Grade 3, T2, two lymph nodes positive, or Her2 positive were the main causes of worse survival in the axillary conservation group. CONCLUSION Not all patients with N1 early breast cancer suit axillary conservation. Axillary conservation was sufficient in patients who were treated with lumpectomy. ALND cannot be omitted in patients who were ineligible for the Z0011 and undergoing mastectomy with the following characteristics: T2, Grade 3, two positive lymph nodes, and Her2 positive, which may be better complemented to the Z0011 trial. Hence, under different surgical methods, the clinical precision treatment of ALND or axillary preservation is essential.

Long-term survival after sentinel lymph node biopsy or axillary lymph node dissection in pN0 breast cancer patients: a population-based study. Breast Cancer Res Treat 2022; 196:613-622. [PMID: 36207619 DOI: 10.1007/s10549-022-06746-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 09/11/2022] [Indexed: 11/02/2022]
Abstract
PURPOSE Findings from randomized clinical trials have shown that survival in patients with sentinel lymph node (SLN)-negative breast cancer is noninferior with SLN biopsy (SLNB) alone versus further axillary lymph node dissection (ALND). However, the long-term outcome of these two surgical approaches in pN0 breast cancer patients in real-world setting remains uncertain. METHODS We included patients diagnosed with pathologically staged T1-2N0M0 breast cancer between 2000 and 2015 in surveillance, epidemiology, and end results 18-registry database. Patients were considered to have undergone SLNB alone if they had ≤ 5 examined lymph nodes (ELNs), and ALND if they had ≥ 10 ELNs. The outcomes included overall survival (OS) and breast cancer-specific survival. Propensity score analyses by weighting and matching and multivariable Cox regression analysis were performed to minimize treatment selection bias. RESULTS We included 309,430 patients (253,501 SLNB and 55,929 ALND). In the weighted cohort, ALND was associated with significantly lower OS (hazard ratio [HR] 1.13; 95% confidence interval [CI] 1.10-1.16) and BCSS (HR 1.16; 95% CI 1.10-1.22) compared with SLNB alone. Both the propensity score-matching model and multivariable Cox model demonstrated a survival benefit for SLNB when compared with ALND. Subgroup analyses for key variables did not change these findings. CONCLUSION We found statistically significant differences in OS and BCSS between SLNB and ALND, though the magnitude of these differences was small. Our findings further support that SLNB alone should be the standard of care for patients who do not have metastatic lymph nodes identified during breast cancer surgery.

Abstract
Oncotype DX (ODX) recurrence score (RS) is a validated tool to guide the use of adjuvant chemotherapy (AC) in hormone receptor+/HER2- breast cancer. In this analysis, we examine (1) characteristics associated with ODX testing and (2) the association between ODX RS and receipt of AC across age and nodal status. Women with HR+/HER2–, early-stage (T1-2, N0-1) breast cancers from 2010–2017 in the National Cancer Database were included. 530,125 met inclusion and 255,971 received ODX testing. Older women were less likely to receive testing; however, nodal positivity increased use of testing. High ODX RS was associated with increased mortality, though the association was not consistent across age and was most strongly associated with mortality among younger, node-negative women. Older women with high ODX RS, regardless of nodal status, were less likely to receive AC. Clinicians may be employing ODX RS to support treatment decisions against the receipt of AC.

Abstract
INTRODUCTION Accurately assessing axillary lymph node (ALN) status in breast cancer is vital for clinical decision making and prognosis. The purpose of this study was to evaluate the predictive value of sentinel lymph node (SLN) mapped by multidetector-row computed tomography lymphography (MDCT-LG) for ALN metastasis in breast cancer patients. METHODS 112 patients with breast cancer who underwent preoperative MDCT-LG examination were included in the study. Long-axis diameter, short-axis diameter, ratio of long-/short-axis and cortical thickness were measured. Logistic regression analysis was performed to evaluate independent predictors associated with ALN metastasis. The prediction of ALN metastasis was determined with related variables of SLN using receiver operating characteristic (ROC) curve analysis. RESULTS Among the 112 cases, 35 (30.8%) cases had ALN metastasis. The cortical thickness in metastatic ALN group was significantly thicker than that in non-metastatic ALN group (4.0 ± 1.2 mm vs. 2.4 ± 0.7 mm, P < 0.001). Multi-logistic regression analysis indicated that cortical thickness of > 3.3 mm (OR 24.53, 95% CI 6.58-91.48, P < 0.001) had higher risk for ALN metastasis. The best sensitivity, specificity, negative predictive value(NPV) and AUC of MDCT-LG for ALN metastasis prediction based on the single variable of cortical thickness were 76.2%, 88.5%, 90.2% and 0.872 (95% CI 0.773-0.939, P < 0.001), respectively. CONCLUSION ALN status can be predicted using the imaging features of SLN which was mapped on MDCT-LG in breast cancer patients. Besides, it may be helpful to select true negative lymph nodes in patients with early breast cancer, and SLN biopsy can be avoided in clinically and radiographically negative axilla.

Abstract
BACKGROUND Surgical axillary staging demonstrating positive nodal disease before neoadjuvant chemotherapy (NAC) necessitates axillary lymph node dissection (ALND) post-NAC. Despite evidence supporting post-NAC surgical staging, we hypothesized that there is persistent use of pre-NAC staging and that it is associated with aggressive clinicopathologic features and a higher rate of subsequent ALND. PATIENTS AND METHODS Stage I-III breast cancer patients who underwent lymph node staging surgery and received NAC between 2013 and 2017 in the National Cancer Database were included. Sequence of staging surgery and chemotherapy administration was determined. Multivariable regression was used to assess characteristics associated with pre-NAC staging. Rate of ALND was compared between those who had pre- and post-NAC surgical axillary staging. RESULTS In total, 120,538 met inclusion; 68% received NAC first and 32% had pre-NAC staging. Pre-NAC staging surgery was associated with younger age (age < 30 versus 40-49 years, HR 1.1) and decreased with older age (ages 70-79/80+ versus 40-49 years, HR 0.86 and 0.73). Advancing clinical T stage, lobular subtype, higher grade, and HR+/HER2- subtype were also associated with pre-NAC surgical staging. Women who underwent pre-NAC surgical staging were more likely to undergo ALND. CONCLUSIONS Over 30% of women underwent surgical axillary staging prior to NAC, resulting in higher rates of ALND in this cohort. While certain features suggestive of aggressive behavior (grade and T stage) were associated with pre-NAC surgical axillary staging, women with more aggressive tumor subtypes (triple negative/HER2+) were less likely to undergo pre-NAC surgical axillary staging. Pre-NAC surgical axillary staging should be performed only in rare circumstances to avoid unnecessary ALND.

Abstract
BACKGROUND Multiple primary malignancies are two or more malignancies in an individual without any relationship between the tumors. The development of improved diagnostic techniques, increased survival of cancer patients and the growing life expectancy have all contributed to the increased frequency of this phenomenon. OBJECTIVE The aim of this study is to review the multidetector computed tomography (MDCT) findings of synchronous breast carcinoma and other solid malignancies. METHODS This retrospective study included 65 patients confirmed with diagnosis of synchronous breast carcinoma and other solid malignancies. CT scanning was performed using 128 MDCT in all patients. All one hundred-thirty malignancies underwent pathological evaluation. RESULTS Out of 4120 patients with breast carcinoma; 65 patients were diagnosed with other synchronous primary solid malignancy. All one hundred-thirty malignancies were confirmed pathologically. Breast carcinoma detected in all 65 patients; of them metastatic breast carcinoma detected in 8 patients. Hepatocellular carcinoma was detected in 18 patients, Non-Hodgkin lymphoma (NHL) in 12 patients, endometrial carcinoma in 8 patients, uterine sarcoma in 3 patients, malignant mixed Müllerian tumor in one patient, ovarian carcinoma in 5 patients, renal cell carcinoma in 4 patients, thyroid carcinoma in 4 patients, gastric carcinoma in 2 patients, colonic carcinoma in 2 patients, ano-rectal carcinoma in one patient, hilar cholangiocarcinoma in 2 patients, malignant melanoma in 2 patients and bronchogenic carcinoma in one patient. CONCLUSIONS Patients with breast carcinoma have a risk of other synchronous primary malignancy. So, careful preoperative examination is recommended to improve the patients' prognosis. MDCT scanning is accurately imaging modality for evaluation of synchronous breast carcinoma and other solid malignancies. The aim of treatment in cancer patients should always be curative even in the presence of multiple malignancies.

Abstract
Well executed multicenter clinical trials often provide significant evidence and support for, or against, foundational aspects of clinical procedures perceived to improve clinical management of a medical condition. In this review, discussed are reports of multicenter clinical trials designed to investigate sentinel lymph node biopsy procedures in seven types of cancer: breast, melanoma, head and neck, gastric, colon, uterine, and vulvar-with focus on the most recent reports of the hypotheses, objectives, parameters, data, results, implications, and impacts of the included trials. Such trials generally enroll more subjects, in shorter time periods, than do single-center studies. Such studies generally also have greater diversities among investigator practitioners and investigative environments than do single-center studies. The greater number of subjects provides more power to statistical analyses performed in such studies. The more rapid accrual usually results in data being more consistently acquired. The diversities of practitioners and environments may produce results that are more conservative than might be obtained from more "focused" studies; however, diversities in a study often identify implicitly results that are more robust-that is results applicable by more practitioners and applicable in more environments.

Abstract
BACKGROUND Variation in breast cancer surgical practice patterns can lead to poor clinical outcomes. It is important to measure and reduce variation to ensure all women diagnosed with breast cancer receive equitable, high-quality care. A population-based assessment of the variation in breast cancer surgery treatment and quality has never been conducted in Manitoba. The objective of this study was to assess the variation in surgical treatment patterns, quality of care, and post-operative outcomes for women diagnosed with invasive breast cancer. METHODS This descriptive study used data from the Manitoba Cancer Registry, Hospital Discharge Abstracts Database, Medical Claims, Manitoba Health Insurance Registry, and Statistics Canada. The study included women in Manitoba aged 20+ and diagnosed with invasive breast cancer between 1 January 2010 and 31 December 2014. RESULTS Axillary lymph node dissection (ALND) for node-negative disease ranged from 11.8% to 33.3%, timeliness (surgery within 30 days of consult) ranged from 33.3% to 60.2%, and re-excision ranged from 14.7% to 24.6% between health authorities. Women who underwent breast-conserving surgery had the shortest median length of stay and women who underwent mastectomy with immediate reconstruction had the longest median length of stay. In-hospital post-operative complications were higher among women who received mastectomy with immediate reconstruction (9.9%). CONCLUSION Variation in surgical treatment, quality, and outcomes exist in Manitoba. The findings from this study can be used to inform cancer service delivery planning, quality improvement efforts, and policy development. Influencing data-driven change at the health system level is paramount to ensuring Manitobans receive the highest quality of care.

Abstract
BACKGROUND Clinical trials have long established the long-term safety of omitting axillary lymph node dissection (ALND) after sentinel lymph node dissection (SLND) in patients with clinically node-negative early stage breast cancer. The variations in utilization of SLND and ALND in this patient population, however, are currently unknown. METHODS Adult female patients (40 years and older) within the National Cancer Database diagnosed with breast cancer between January 2013 and December 2015, who had clinical T1-T2 and N0 disease, and who underwent either SLND (with or without subsequent ALND) or ALND were included. Differences in utilization across race, ethnicity, insurance type, facility, and residential characteristics were assessed using multivariable logistic regression. RESULTS Overall, 271,689 patients were included, of which 26,527 (10%) received ALND and 245,162 (90%) underwent SLND. After adjusting for demographics and cancer characteristics, black (odds ratio [OR], 1.11; 95% confidence interval [95% CI], 1.06-1.17) and Hispanic women (OR, 1.16; 95% CI, 1.10-1.24) were more likely to receive ALND. Patients without health insurance (OR, 1.33; 95% CI, 1.19-1.47), compared with private health insurance, and those receiving treatment at community cancer centers (OR, 1.60; 95% CI, 1.53-1.67), compared with academic/research centers, were also more likely to receive ALND. CONCLUSIONS Although the vast majority of women undergo SLND, significant disparities exist in its utilization for early stage breast cancer, with traditionally underserved patients receiving unwarranted extensive axillary surgery. Increased patient and surgeon education is needed to decrease variations in care that can affect patient's quality of life.

Decreasing rates of axillary lymph node dissections over time: Implications for surgical resident exposure and operative skills development. Am J Surg 2019; 218:786-791. [PMID: 31350006 DOI: 10.1016/j.amjsurg.2019.07.013] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2019] [Revised: 04/23/2019] [Accepted: 07/16/2019] [Indexed: 12/15/2022]
Abstract
BACKGROUND Sentinel lymph node biopsy has supplanted axillary lymph node dissection (ALND) in clinically node-negative breast cancer and select node-positive disease. We hypothesized a decreasing rate of both ALND and resident exposure over time. METHODS We identified women with clinical Stage I-III breast cancer in the National Cancer Data Base (2004-2014). Adjusted multivariate logistic regression was used to estimate the effect of various factors on receipt of ALND. Yearly procedural rates for residents were extracted from surgical case log reports for comparison against procedural rates. RESULTS 1,131,363 patients were identified; 255,306 received ALND, 876,057 underwent non-ALND management. ALND rates declined from 2004 (32%) to 2014 (16%, p < 0.001), with the largest decline occurring between 2010 and 2011 (24%-20%). After adjustment, this effect was maintained, with ALND rates decreasing with each additional year (OR = 0.90, 95% CI 0.89-0.90). Resident procedure volumes similarly declined from 1999 to 2017 (p < 0.001). CONCLUSIONS Significant declines in both ALND rates and procedural volume in residency may impact outcomes, as ALNDs are being performed in ever more challenging oncologic scenarios by potentially less-experienced surgeons.

Predictive Value of Preoperative Multidetector-Row Computed Tomography for Axillary Lymph Nodes Metastasis in Patients With Breast Cancer. Front Oncol 2019; 8:666. [PMID: 30671386 PMCID: PMC6331431 DOI: 10.3389/fonc.2018.00666] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2018] [Accepted: 12/17/2018] [Indexed: 02/05/2023] Open
Abstract
Introduction: Axillary lymph nodes (ALN) status is an essential component in tumor staging and treatment planning for patients with breast cancer. The aim of present study was to evaluate the predictive value of preoperative multidetector-row computed tomography (MDCT) for ALN metastasis in breast cancer patients. Methods: A total of 148 cases underwent preoperative MDCT examination and ALN surgery were eligible for the study. Logistic regression analysis of MDCT variates was used to estimate independent predictive factors for ALN metastasis. The prediction of ALN metastasis was determined with MDCT variates through receiver operating characteristic (ROC) analysis. Results: Among the 148 cases, 61 (41.2%) cases had ALN metastasis. The cortical thickness in metastatic ALN was significantly thicker than that in non-metastatic ALN (7.5 ± 5.0 mm vs. 2.6 ± 2.8 mm, P < 0.001). Multi-logistic regression analysis indicated that cortical thickness of >3 mm (OR: 12.32, 95% CI: 4.50–33.75, P < 0.001) and non-fatty hilum (OR: 5.38, 95% CI: 1.51–19.19, P = 0.009) were independent predictors for ALN metastasis. The sensitivity, specificity and AUC of MDCT for ALN metastasis prediction based on combined-variated analysis were 85.3%, 87.4%, and 0.893 (95% CI: 0.832–0.938, P < 0.001), respectively. Conclusions: Cortical thickness (>3 mm) and non-fatty hilum of MDCT were independent predictors for ALN metastasis. MDCT is a potent imaging tool for predicting ALN metastasis in breast cancer. Future prospective study on the value of contrast enhanced MDCT in preoperative ALN evaluation is warranted.
