Measurement of extracapsular extension in sentinel lymph node as a possible predictor of residual axillary disease in breast cancer. Clinics (Sao Paulo) 2023; 78:100216. [PMID: 37201303 DOI: 10.1016/j.clinsp.2023.100216] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 04/11/2023] [Accepted: 04/27/2023] [Indexed: 05/20/2023] Open
Abstract
BACKGROUND The presence of Extracapsular Extension (ECE) in the Sentinel Lymph Node Biopsy (SLNB) is still a doubt in the literature. Some studies suggest that the presence of ECE may be related to a greater number of positive axillary lymph nodes which could impact Disease Free Survival (DFS) and Overall Survival (OS). This study searches for the clinical significance of the ECE. METHODS Retrospective cohort comparing the presence or absence of ECE in T1-2 invasive breast cancer with positive SLNB. All cases treated surgically at the Cancer Institute of the State of São Paulo (ICESP) between 2009 and 2013 were analyzed. All patients with axillary disease in SLNB underwent AD. OUTCOMES Identify the association between the presence and length of ECE and additional axillary positive lymph nodes, OS and DFS between both groups. RESULTS 128 patients with positive SLNB were included, and 65 had ECE. The mean metastasis size of 0.62 (SD = 0.59) mm at SLNB was related to the presence of ECE (p < 0.008). The presence of ECE was related to a higher mean of positive sentinel lymph nodes, 3.9 (± 4.8) vs. 2.0 (± 2.1), p = 0.001. The median length of follow-up was 115 months. The OS and DFS rates had no differences between the groups. CONCLUSION The presence of ECE was associated with additional positive axillary lymph nodes in this study. Therefore, the OS and DFS were similar in both groups after 10 years of follow-up. It is necessary for additional studies to define the importance of AD when SLNB with ECE.

Abstract
Regional lymph node status impacts survival in dogs with malignant mammary tumors. However, few studies have evaluated extracapsular extension and tumor implants in regional lymph node metastases in dogs with mammary carcinoma. Therefore, 84 cases of mammary carcinomas with metastases in inguinal and/or axillary lymph nodes from female dogs of different breeds and a total of 139 metastatic lymph nodes were evaluated by routine histological staining. Clinical and pathological characteristics of primary tumors as well as the presence of extracapsular extension and tumor implants in the lymph nodes were analyzed, in addition to survival. One to 5 lymph nodes were evaluated in each case. Extracapsular extension and tumor implants were present in 17.9% and 39.3% of cases, respectively. The simultaneous presence of extracapsular extension and tumor implants were associated with an increased risk of death (hazard ratio 10.46). In addition, "special type carcinomas", high histological grade (grade III), and presence of extracapsular extension associated with tumor implants were related to a worse prognosis and shorter survival times (p < 0.05). Based on these results, we highlight the importance of identifying extracapsular extension and tumor implants in dogs with metastatic mammary carcinomas, as they are associated with a higher risk of death and shorter survival.

Abstract
The purpose of this study was to evaluate the presence of extracapsular invasion (ECI) in positive sentinel lymph nodes (SLNs) as a predictor of disease recurrence in breast cancer. SLN biopsy was performed on 318 breasts of 316 breast cancer patients, of which 50 (15.7%) had positive SLNs. Six (12.0%) of these 50 cases had disease recurrence. The clinicopathologic features of these cases were reviewed. The ECI at SLNs was not significantly associated with disease recurrence. The recurrence-free interval by Kaplan-Meier curves did not differ significantly among patients with and without ECI at SLNs. On the other hand, metastasis at non-SLNs was observed in 12 cases (24.0%) among the 50 cases with positive SLNs, and in the non-SLN metastasis group there were 7 patients with ECI at non-SLNs. Three of 7 cases with ECI at non-SLNs had disease recurrence and none of those 5 without ECI at non-SLNs had disease recurrence. Our current study suggests that the presence of ECI at metastatic SLNs is not associated with recurrent disease in breast cancer. Our results also imply that patients with ECI at positive non-SLNs have a high risk of disease recurrence.

Abstract
BACKGROUND The status of the axillary lymph nodes is an important factor in the prognosis and treatment of breast cancer. Extracapsular extension (ECE) is the spread of lymphatic tumor cells beyond the capsule of an axillary lymph node. Recent studies have demonstrated that ECE is a strongly unfavorable prognostic factor. OBJECTIVE In the present study, we investigated whether the rate of metastasis among examined lymph nodes can be used to predict ECE in patients with axillary node-positive breast cancer. METHODS The subjects were 95 women with axillary node-positive breast cancer. The numbers of lymph nodes removed (examined) and lymph nodes involved were recorded. The cut-off values, area under the curve, sensitivity, and specificity were calculated with the receiver operating characteristic curve technique for ability of the rate of metastasis to examined lymph nodes to predict ECE. RESULTS The rate of metastasis to examined lymph nodes was significantly greater in patients with ECE than in patients without ECE [0.57 (0.03-1.00) vs. 0.22 (0.04-1.00), respectively, p: 0.001]. Similarly, the presence of vascular infiltration was significantly higher in patients with ECE than in those without ECE [30 (73.2%) vs. 25 (47.2%) respectively, p: 0.010]. On the other hand, other variables did not differ between the groups (p>0.05). When the cut-off value was ≥0.23, the sensitivity and specificity of the rate of metastasis to examined lymph nodes were 80.49% and 55.56%, respectively. The area under the curve was 0.697 (95% confidence interval: 0.594-0.787, p: 0.004). CONCLUSION Our results suggest that rate of metastasis among examined lymph nodes is a predictor of ECE in patients with axillary node-positive breast cancer.

Regulation of anti-apoptotic signaling by Kruppel-like factors 4 and 5 mediates lapatinib resistance in breast cancer. Cell Death Dis 2015; 6:e1699. [PMID: 25789974 PMCID: PMC4385942 DOI: 10.1038/cddis.2015.65] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2014] [Revised: 02/10/2015] [Accepted: 02/12/2015] [Indexed: 02/08/2023]
Abstract
The Kruppel-like transcription factors (KLFs) 4 and 5 (KLF4/5) are coexpressed in mouse embryonic stem cells, where they function redundantly to maintain pluripotency. In mammary carcinoma, KLF4/5 can each impact the malignant phenotype, but potential linkages to drug resistance remain unclear. In primary human breast cancers, we observed a positive correlation between KLF4/5 transcript abundance, particularly in the human epidermal growth factor receptor 2 (HER2)-enriched subtype. Furthermore, KLF4/5 protein was rapidly upregulated in human breast cancer cells following treatment with the HER2/epidermal growth factor receptor inhibitor, lapatinib. In addition, we observed a positive correlation between these factors in the primary tumors of genetically engineered mouse models (GEMMs). In particular, the levels of both factors were enriched in the basal-like tumors of the C3(1) TAg (SV40 large T antigen transgenic mice under control of the C3(1)/prostatein promoter) GEMM. Using tumor cells derived from this model as well as human breast cancer cells, suppression of KLF4 and/or KLF5 sensitized HER2-overexpressing cells to lapatinib. Indicating cooperativity, greater effects were observed when both genes were depleted. KLF4/5-deficient cells had reduced basal mRNA and protein levels of the anti-apoptotic factors myeloid cell leukemia 1 (MCL1) and B-cell lymphoma-extra large (BCL-XL). Moreover, MCL1 was upregulated by lapatinib in a KLF4/5-dependent manner, and enforced expression of MCL1 in KLF4/5-deficient cells restored drug resistance. In addition, combined suppression of KLF4/5 in cultured tumor cells additively inhibited anchorage-independent growth, resistance to anoikis and tumor formation in immunocompromised mice. Consistent with their cooperative role in drug resistance and other malignant properties, KLF4/5 levels selectively stratified human HER2-enriched breast cancer by distant metastasis-free survival. These results identify KLF4 and KLF5 as cooperating protumorigenic factors and critical participants in resistance to lapatinib, furthering the rationale for combining anti-MCL1/BCL-XL inhibitors with conventional HER2-targeted therapies.

Abstract
CONTEXT Lymph node status and the number of lymph node (LN) positive for cancer cells are the most important prognostic factors in breast cancer. Extranodal tumor extension (ENTE) has been used as a histopathologic feature to classify patients into high risk versus low risk for local recurrence. However, in the current era of early detection and systemic therapy, the prognostic significance of ENTE is not as well defined in patients with 1 to 3 LNs positive for cancer. OBJECTIVE To determine whether the amount of tumor burden in an axillary dissection or the presence of ENTE provides any additional information regarding patient outcome in patents with 1 to 3 positive LN results. DESIGN Clinical and pathologic factors were identified for 456 patients with breast cancer at the University of Texas MD Anderson Cancer Center, Houston, who had pT1 tumors and 1 to 3 LNs positive for cancer and were treated by mastectomy, with or without postmastectomy radiotherapy, between 1978 and 2007. RESULTS Of the 456 patients, 257 (56.4%), 141 (31.6%), and 58 (12.7%) patients had 1, 2, or 3 positive LN results, respectively. Extranodal tumor extension was present in 99 patients (21.7%) and was absent in the remaining 357 cases (78.3%). Seventy-six patients (16.7%) received radiation therapy. Patients had both worse overall survival time and disease-free survival when ENTE was present, regardless of the amount, as long as the treatment era was not included in the multivariate analysis (pre-2000 versus post-2000). However, ENTE was no longer significant on multivariate analysis when the year of treatment was taken into account. CONCLUSIONS The number of positive LNs remains an important predictor of survival in patients with 1 to 3 positive LN results, but the prognostic significance of ENTE in this cohort of patients has diminished over time.

Abstract
American College of Surgeons Oncology Group Z0011 concluded that axillary lymph node dissection (ALND) may be avoided in selected patients with breast cancer with limited axillary nodal metastasis on sentinel lymph node dissection (SLND). However, patients with extranodal extension (ENE) were excluded to the follow existing standard of care, which is completion ALND. The significance of ENE detected on SLND is not well defined. Our objective was to determine the impact of ENE found on SLND on nonsentinel lymph node (NSLN) metastasis, recurrence, and overall mortality. We evaluated patients with breast cancer treated at a tertiary cancer center from 2005 to 2012. SLND was performed in 655 patients. Of those, 478 of 655 (73.0%) patients had no SLN metastases, 124 of 655 (18.9%) had SLN metastases without ENE (SLN-ENE), and 53 of 655 (8.1%) had SLN metastases with ENE (SLN1ENE). Of patients undergoing ALND, NSLN metastasis was detected in 37 of 84 (44.0%) of patients in the SLN-ENE group and 26 of 45 (57.8%) patients in the SLN1ENE group ( P = 0.14). On adjusted analyses, ENE was associated with increased disease recurrence (odds ratio [OR], 5.48; 95% confidence interval [CI], 1.23 to 24.48; P = 0.03) as well as increased overall mortality (OR, 8.16; 95% CI, 1.72 to 38.63; P = 0.01). In conclusion, ENE is associated with increased overall axillary nodal burden, disease recurrence, and overall mortality.

Abstract
OBJECTIVE The purpose of this study was to assess the accuracy of 5 sonographic features in the prediction of extranodal extension (ENE) in axillary lymph nodes (ALNs) of patients with biopsy-proven breast cancer. METHODS A review of our institution's surgical and pathologic database was performed for patients with pathologically proven axillary ENE from October 1, 2003, to October 1, 2007. An equivalent number of patients without ENE were included. All patients had sonograms of ALNs available. A radiologist to whom the study was masked reviewed ALN images with specific attention to unclear margins, node matting, perinodal edema, and hilar effacement or replacement. Univariate and multivariate logistic regression analyses were used to obtain the sensitivity, specificity, and odds ratio (OR) for each feature. RESULTS Our review included a total of 131 patients (64 with ENE and 67 without ENE). The respective sensitivity and specificity estimates for each feature were as follows: node matting, 52% and 84%; perinodal edema, 34% and 87%; unclear margins, 64% and 75%; hilar replacement, 71% and 42%; and hilar effacement, 74% and 60%. Univariate analysis showed a statistically significant association between features and ENE with ORs as follows: matting, 5.4; perinodal edema, 3.4; unclear margins, 5.2; and hilar replacement, 4.3. Multivariate analysis showed that matting and unclear margins were independently associated with ENE. CONCLUSIONS The sonographic features of unclear margins, node matting, perinodal edema, and hilar replacement have a statistically significant association with ENE. The sonographic features of unclear margins, node matting, and perinodal edema predict ENE with high specificity.

Abstract
The aim of this prospective study was to investigate the effects of early onset rehabilitation program on shoulder mobility, functional status, lymphedema, and the incidence of postoperative complications in patients who had modified radical mastectomy. Fifty-seven women were randomly assigned to either treatment group or home exercise program groups, which were consisted of 27 and 30 patients, respectively. After removal of the drains, the patients were instructed to 15 sessions of individual rehabilitation program and continued with home-based physical activity program. The home exercise program groups only received a form including the exercises, which could be performed by themselves after removal of the drains. Range of motion of the shoulder joint and upper extremity circumferential difference were measured. Functional status was assessed by functional index score. Each patient was assessed preoperatively and then postoperatively at fifth day and first, third, and sixth months. The improvement in measurements of flexion, abduction, and adduction movements of the shoulder joint and the functional questionnaire scores were significantly better in treatment group. There was no statistically significant difference in the development of lymphedema and postoperative complications in both groups. Early onset rehabilitation program after modified radical mastectomy provides improvement in shoulder mobility and functional capacity without causing adverse effect in postoperative period.

Abstract
BACKGROUND Extracapsular extension of nodal tumor cells, although it is not a parameter of staging, has recently been shown to be correlated with the high number of metastatic lymph nodes in patients with axillary-positive breast cancer. It is suggested that the use of involved/examined lymph node ratio instead of the number of metastatic lymph nodes in axillary evaluation would obtain standardized prognostic data for patient management. This study investigated the association of the extracapsular extension with the lymph node ratio in a node-positive group of patients. PATIENTS AND METHODS Medical records of 170 patients with positive axillary status were retrospectively reviewed. Of these, 54 were extracapsular extension positive, and the remaining were extracapsular extension negative. A comparison was made between extracapsular extension-positive and extracapsular extension-negative groups with respect to some potential prognostic indicators. RESULTS Number of metastatic lymph nodes, number of examined lymph nodes, and involved/examined lymph node ratio were found to be significantly higher in patients with a presence of extracapsular extension. CONCLUSION The results suggest that the presence of extracapsular extension might force physicians to perform more aggressive adjuvant therapies and that the extracapsular extension could be a valuable parameter in the management of breast cancer because it has a strong relationship with the proven prognostic factors.

Abstract
BACKGROUND The presence of extranodal invasion (ENI) in the metastatic lymph nodes is reported to increase the risk of locoregional recurrence while shortening disease-free and overall survival in patients with breast cancer. In this study the relationship between ENI and other prognostic parameters and survival is investigated. METHODS Of 650 patients with breast cancer who were treated in Ankara Oncology Teaching and Research Hospital from 1996 to 2003, 368 (56.6%) had lymph node metastasis. The patients with axillary metastasis were separated into two groups as with and without invasion to lymph node capsule and the surrounding adipose tissue. Clinicopathologic features were analyzed by univariate and multivariate logistic regression. RESULTS Of 368 patients with axillary metastasis, 135 (36.7%) had ENI. Based on multivariate analysis; the number of metastatic lymph nodes, lymphatic invasion, and tumor necrosis were found to be related with ENI. In the group with ENI, 5-year overall survival rate was 74.8%, compared to 82.3% for patients without ENI which was significantly lower (P = 0.04). CONCLUSIONS In lymph node positive breast cancer with presence of ENI, adverse prognostic parameters are more frequently encountered and has a worse overall survival compared to group without ENI.

Abstract
The number of positive lymph nodes (+LNs) is the only node-related prognostic factor recognized by the American Joint Committee TNM system for breast cancer. In this study, we evaluated additional node-related prognostic factors in node-positive breast carcinomas. One hundred and thirty-four patients with infiltrating ductal carcinomas and axillary +LNs, who had been treated with modified radical mastectomy, were analyzed. Metastatic lymph nodes were evaluated for traditional prognostic factors, i.e., the number of involved nodes and the extranodal extension, but also for a variety of other node-related characteristics, such as nodal tumor burden and maximum size of tumor deposits, necrosis, stromatogenesis, extranodal vascular involvement, and nodal matting. The results reaffirmed the prognostic significance of metastasis in 1-3 vs. 4-7 axillary lymph nodes and, in addition, revealed the importance of 4 +LNs as a cut-off point for breast tumor aggressiveness, given that survival curves for 4-7 vs. >7 +LNs were indifferent. Interestingly, nodal tumor burden, when extensive, was statistically an adverse prognostic factor. Prognosis was equally poor if metastases to regional nodes showed extensive nodal necrosis or extensive nodal stromatogenesis, if there was extranodal spread, extranodal vascular involvement, or if the axillary +LNs were matted. In multivariate analysis, intranodal necrosis and extranodal vascular involvement were the only node-related features with a significant and independent prognostic function. Node-related pathological features in node-positive breast carcinomas are important in determining prognosis. Intranodal necrosis and extranodal tumor emboli should be considered, in parallel with the number of +LNs, in subsequent treatment design.
