[PMID: 39057116 PMCID: PMC11276503 DOI: 10.3390/diseases12070145] [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: 04/28/2024] [Revised: 06/16/2024] [Accepted: 06/26/2024] [Indexed: 07/28/2024] Open
Abstract
Post-operative radiotherapy for post-menopausal women with early breast cancer and N1 disease is controversial. Although locoregional control is improved, overall survival (OS) benefit is unclear. The clinical benefit of post-operative irradiation in this group of patients over 10 years was reviewed. We aimed to evaluate the OS, disease-free survival (DFS), and factors affecting OS and DFS. A retrospective review of 191 post-menopausal women with early breast cancer and N1 disease from 2004 to 2011 was performed. Demographics, post-operative histology, adjuvant treatment, OS, and DFS were evaluated. Post-operative radiation was given to 95 of 191 women (49.7%). Younger age at diagnosis (p < 0.001), a greater number of involved nodes (p = 0.004), lymphovascular invasion (LVI), and a higher tumor grade (p = 0.001) were more likely in women who received post-operative radiation. Nodal radiation did not improve 10-year DFS (p = 0.084) or OS (p = 0.203). Post-operative nodal radiation was associated with significant improvement in 10-year OS in women who received only hormonal therapy (p = 0.047) and no other systemic therapy. Women with unfavorable risk factors were more likely to receive post-operative radiation, likely due to a perceived higher risk of recurrence. Nodal radiation did not significantly improve 10-year DFS or OS in early breast cancer patients with N1 disease, and the benefit was not clearly demonstrated. However, in those who were on hormonal therapy, radiotherapy was beneficial in improving overall survival.

Accuracy of Intraoperative Frozen Section Analysis of Lymph Nodes in Women Undergoing Axillary Sampling for Treatment of Breast Cancer: Single Institution Audit. Clin Breast Cancer 2023; 23:e420-e423. [PMID: 37460382 DOI: 10.1016/j.clbc.2023.06.010] [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: 03/27/2023] [Revised: 06/19/2023] [Accepted: 06/21/2023] [Indexed: 09/30/2023]
Abstract
BACKGROUND Axillary lymph node (LN) positivity is an important prognostic factor in breast cancer. Almost 30% clinically node negative (cN0) early breast cancers have positive nodes on pathology, wherein an axillary dissection is done as a second stage surgery. Intra operative frozen section (FS) potentially avoids redo surgery. MATERIALS AND METHODS We performed a retrospective audit for the false negative rate of intraoperative FS, from 2014 to 2018. All cN0 women undergoing upfront surgery, who underwent low axillary sampling (LAS) with FS were included. RESULTS Of 22,854 breast cancer cases, 2230 underwent LAS, of which 877 were node positive. Intraoperative FS was negative in 1423/2230 (63.81%) cases, of which 71/1423 (4.98%) were false negative, and came positive on final histopathology report (HPR). These 71 women had a median of 5 nodes (mean 4.85) dissected on FS (range 1-12) with a median 1 (mean 1.3) node positive (range 1-6) on HPR. The sensitivity of FS was 91.89% (95% CI, 89.89-93.62), with a negative predictive value of 95.01% (95% CI, 93.84-95.97), accuracy of 96.73% (95% CI, 95.90-97.43) and false negative rate 4.98%. On logistic regression analysis, micrometastasis (Odds ratio (OR) 7.76, 95% CI, 3.49-17.25, P < .001) lobular histology (OR 2.50, 95% CI, 1.007-6.223, P = .04) and nodes dissected (OR 1.18, 95% CI, 1.07-1.30, P = .001) were associated with higher false negative FS, and extra nodal extension (OR 0.32, 95% CI, 0.18-0.57, P ≤ .001) with lower false negative FS. CONCLUSION The high concordance between intraoperative FS and definitive histology, suggests it's routine use for Sentinel lymph node/LAS LN can help avoid a second surgery.

Evaluation of Intraoperative Frozen Section Analysis with Final Histopathology Results for Sentinel Lymph Node Biopsy: Z0011 Criteria Eligible Versus Ineligible Breast Cancer
Patients. Geburtshilfe Frauenheilkd 2022; 82:610-618. [PMID: 35903717 PMCID: PMC9315401 DOI: 10.1055/a-1749-5226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Accepted: 01/24/2022] [Indexed: 11/21/2022] Open
Abstract
Background
Intraoperative frozen section analysis (FSA) of sentinel lymph nodes (SLNs) declined in the post American College of Surgeons Oncology Group Z0011 (ACOSOG Z0011) trial
era. However, for those patients who do not meet the ACOSOG Z0011 criteria, FSA continues to be a valuable tool in intraoperative decision-making for axillary lymph node dissection (ALND).
The aim of this study was therefore to retrospectively evaluate the benefit and accuracy of FSA of Z0011 criteria eligible versus ineligible patients and identify possible predictive factors
for false negative results.
Methods
Intraoperative FSA was performed on SLNs of 522 cT1–T3 breast cancer patients between 2008 and 2013. Clinicopathologic characteristics were retrospectively assessed by chart
review.
Results
Overall FSA sensitivity and specificity was 67.8% and 100%. Sensitivity was generally higher for macrometastasis than for micrometastasis. The Z0011 eligible group showed a
sensitivity and specificity of 72.7% and 100% versus 62.1% and 100% in the Z0011 ineligible group. Importantly, subgroup analysis of ≤ 2 versus > 2 positive SLNs of the Z0011 eligible
group demonstrated both a 100% specificity and sensitivity. Several clinicopathologic factors were associated with a higher rate of false negative results in the Z0011 ineligible patient
group. FSA was beneficial for 22.2% of Z0011 ineligible patients and for only 0.6% of Z0011 eligible patients regarding intraoperative decision-making for ALND.
Conclusions
FSA continues to be especially beneficial in the intraoperative assessment of SLNs in the Z0011 ineligible group to prevent second stage ALND. Despite an overall lower
FSA sensitivity in the Z0011 eligible patient group, FSA offers in both groups a comparable high sensitivity and diagnostic accuracy for macrometastasis.

Axillary Lymph Node Dissection Can Be Omitted in Breast Cancer Patients With Mastectomy and False-Negative Frozen Section in Sentinel Lymph Node Biopsy. Front Oncol 2022; 12:869864.

Abstract
Background The IBCSG 23-01 and AMAROS trials both reported that axillary lymph node dissection (ALND) did not change survival rates in breast cancer patients with positive nodes detected by sentinel lymph node biopsy (SLNB). The aim of this study was to determine whether breast cancer patients with mastectomy and false-negative frozen section (FS) in SLNB could forgo ALND. Materials and Methods This was a retrospective study of cN0 patients diagnosed with primary invasive breast cancer treated by mastectomy and SLNB at our institute between January 2010 and December 2014. Patients with false-negative FS in SLNB were separated by the following management of axillary lymph node dissection in the non-ALND group (nonprocess or axillary radiation only) and ALND group (with or without radiation). Results A total of 212 patients were included, 86 and 126 patients in the non-ALND and ALND groups, respectively. The positive rate of non-sentinel lymph nodes (SLNs) was 15.87% (20/126) in the ALND group. In multivariate analysis, we found that patients with larger tumor size (>2 cm) (OR, 1.989; p = 0.030) and multifocal lesions (OR, 3.542; p = 0.029) tended to receive ALND. The positivity of non-SLNs in the ALND group was associated with SLN macrometastasis (OR, 3.551; p = 0.043) and lymphovascular invasion (OR, 6.158; p = 0.003). Also, removing more SLNs (≥3) was related to negativity in non-SLNs (OR, 0.255; p = 0.016). After a median follow-up of 59.43 months, RFS and OS of the two groups were similar (p = 0.994 and 0.441). In subgroup analysis, we found that 97 patients who met the inclusive criteria of the IBCSG 23-01 trial had similar RFS and OS between the non-ALND and ALND groups (p = 0.856 and 0.298). The positive rate of non-SLNs was 9.62% (5/52). Also, in 174 patients who met the criteria of the AMAROS trial, RFS and OS in the non-ALND and ALND groups were similar (p = 0.930 and 0.616). The positive rate of non-SLNs was 18.27% (19/104). Conclusion ALND can be carefully omitted in selected breast cancer patients with mastectomy and false-negative FS in SLNB. SLNB is relatively sufficient in the IBCSG 23-01-eligible patients, and axillary radiation was an effective option in the AMAROS-eligible patients.

Abstract
Background Sentinel lymph node biopsy (SLNB) is the standard approach for the axillary region in early breast cancer patients with clinically negative nodes. The present study investigated patients with false-negative sentinel nodes in intraoperative frozen sections (FNSN) using real-world data. Methods A case–control study with a 1:3 ratio was conducted. FNSN was determined when sentinel nodes (SNs) were negative in frozen sections but positive for metastasis in formalin-fixed paraffin-embedded (FFPE) sections. The control was defined as having no metastasis of SNs in both frozen and FFPE sections. Results A total of 20 FNSN cases and 60 matched controls from 333 SLNB patients were enrolled between April 1, 2005, and November 31, 2009. The demographics and intrinsic subtypes of breast cancer were similar between the FNSN and control groups. The FNSN patients had larger tumor sizes on preoperative mammography (P = 0.033) and more lymphatic tumor emboli on core biopsy (P < 0.001). Four FNSN patients had metastasis in nonrelevant SNs. Another 16 FNSN patients had benign lymphoid hyperplasia of SNs in frozen sections and metastasis in the same SNs from FFPE sections. Micrometastasis was detected in seven of 16 patients, and metastases in nonrelevant SNs were recognized in two patients. All FNSN patients underwent a second operation with axillary lymph node dissection (ALND). After a median follow-up of 143 months, no FNSN patients developed breast cancer recurrence. The disease-free survival, breast cancer-specific survival, and overall survival in FNSN were not inferior to those in controls. Conclusions Patients with a larger tumor size and more lymphatic tumor emboli have a higher incidence of FNSN. However, the outcomes of FNSN patients after completing ALND were noninferior to those without SN metastasis. ALND provides a correct staging for patients with metastasis in nonsentinel axillary lymph nodes.

Abstract
BACKGROUND Shift toward minimizing axillary lymph node dissection in patients with breast cancer post neoadjuvant therapy has led to the assessment of sentinel lymph nodes by frozen section intraoperatively to determine the need for axillary lymph node dissection. However, few studies have examined the accuracy of sentinel lymph node frozen section after neoadjuvant therapy. Our objective is to compare the accuracy of sentinel lymph node frozen section in patients with breast cancer with and without neoadjuvant therapy and to identify features that may influence accuracy. DESIGN We identified 161 sentinel lymph node frozen section from 77 neoadjuvant therapy patients and 255 sentinel lymph node frozen section from 88 non-neoadjuvant therapy patients diagnosed between 2010 and 2016 in 2 institutions. The frozen section diagnoses were compared to the final diagnoses, and clinicopathologic data were analyzed. RESULTS The sensitivity, specificity, and accuracy of frozen section analysis were comparable between neoadjuvant therapy patients and non-neoadjuvant therapy patients (71.9% vs 50%, 100% vs 100%, and 88.3% vs 81.8%). Nine (11.7%) of 77 neoadjuvant therapy patients had discordant results, most often due to undersampling (tumor absent on frozen section slide). Four of these patients subsequently underwent axillary lymph node dissection. Discordant results (all false negatives) were significantly more likely in neoadjuvant therapy patients with Estrogen Receptor-positive/HER2-negative status, and in sentinel lymph node with pN1mic and pN0i+ deposits; age, preneoadjuvant therapy lymph node status, histotype, nuclear grade, tumor size, and response to neoadjuvant therapy showed no significant differences. For non-neoadjuvant therapy cases, large tumor size, lobular histotype, and sentinel lymph node with pN1mic and pN0i+ were associated with false-negative frozen section assessment. CONCLUSION Sentinel lymph node frozen section diagnosis post-neoadjuvant therapy has comparable sensitivity, specificity, and accuracy to the sentinel lymph node frozen section diagnosis in the non-neoadjuvant therapy setting.

Abstract
OBJECTIVES There is little information regarding sentinel lymph node (SLN) frozen-section examination in patients with a history of ductal carcinoma in situ (DCIS). We evaluated the usage, clinical impact, and pathology resources used for SLN cryosectioning in mastectomy cases with a DCIS history. METHODS Mastectomies with SLNs submitted from 2012 to 2013 at a tertiary care center were analyzed. Medicare reimbursement was used to estimate pathology health care expenditures of intraoperative frozen sections. RESULTS There was no difference in the rate of SLN frozen-section examination or parts submitted, total blocks frozen, total blocks submitted, or total SLNs identified per case between the DCIS (n = 139) and invasive (n = 369) groups. Nine patients with DCIS had SLN metastases (three macrometastases, two micrometastases, and four isolated tumor cells), all of which were examined by frozen section. Only the macrometastases were identified by cryosectioning, which led to two synchronous axillary lymph node dissections that did not yield any additional positive nodes. A total of $19,313 was spent for pathology per DCIS patient with surgical management affected, whereas only $1,019 was spent per invasive carcinoma patient affected. CONCLUSIONS Decreasing SLN frozen-section use in patients with a history of DCIS represents an opportunity for pathology cost containment.

Abstract
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. We calculated the sensitivity, specificity and accuracy of US/FNAC in predicting the necessity of an axillary lymphadenectomy. Subsequently we looked at the total cost and the operating time of 3 models. Model A is our study protocol. Model B is a theoretical protocol based on the findings of the Z0011 trial with only clinical preoperative staging and in Model C preoperative staging and intraoperative pathological examination were both theoretically done. sentinel node, staging, ultrasound, preoperative axillary staging, FNAC, axilla RESULTS: The sensitivity, specificity and accuracy are respectively 0.75 (0.66-0.82), 1.00 (0.99-1.00) and 0.92 (0.88-0.94). Only 26 out of 317 (8.2%) patients that successfully underwent staging needed a revision. The total cost of Model A was 1.58% cheaper than Model C and resulted in a decrease in operation time by 9,46%. The benefits compared with Model B were much smaller. CONCLUSION Preoperative US/FNAC staging of the axillary lymph nodes can avoid intraoperative examination of the sentinel node with an acceptable revision rate. It saves tissue, reduces operating time and decreases healthcare costs in general.

Abstract
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 (73.6%) of 72 and 19 (25.0%) of 76 in pre- and post-Z0011 groups, respectively. There was post-Z0011 decline in axillary lymph node dissection (ALND) (P = .014) but no difference in later procedures for ALND. SLN positivity was associated with larger (≥1.6 cm) tumor size (P = .002). Nodal upstage was more frequent with invasive lobular (3/32; 9.4%) vs other invasive (2/188; 1.1%) subtypes. CONCLUSIONS Our findings support reduced need for SLN FS for BCT patients post-Z0011. However, those with specific clinicopathologic features may derive greater benefit from SLN FS.

Abstract
Sentinel lymph node (SLN) biopsy has been established as the standard of care for axillary staging in patients with invasive breast carcinoma and clinically negative lymph nodes (cN0). Historically, all patients with a positive SLN underwent axillary lymph node dissection (ALND). The ACOSOG Z0011 trial showed that women with T1-T2 disease and cN0 who undergo breast-conserving surgery and whole-breast radiotherapy can safely avoid ALND. The main goal of SLN examination should be to detect all macrometastases (>2 mm). Gross sectioning of SLNs at 2-mm intervals and microscopic examination of one haematoxylin and eosin-stained section from each SLN block is the preferred method for pathological evaluation of SLNs. The role and timing of SLN biopsy for patients who have received neoadjuvant chemotherapy is controversial, and continues to be explored in clinical trials. SLN biopsies from patients with invasive breast carcinoma who have received neoadjuvant chemotherapy pose particular challenges for pathologists.
