Breast cancer-related lymphedema (BCRL) is a debilitating complication in breast cancer survivors, with axillary lymph node dissection (ALND) as the greatest independent risk factor. Beyond non-surgical therapies such as complete decongestive and compression therapy, there has been increased interest in immediate microsurgical reconstruction via immediate lymphatic reconstruction (ILR) anastomosing transected lymphatic vessels to a local venous recipient at the time of ALND to mitigate the risks of BCRL. This work provides a scoping review of the landscape surrounding ILR, spanning the updated literature investigating patient outcomes, current accepted best practices, and critical components of surgical techniques for a successful multidisciplinary approach. While limited by heterogeneity in the methods of lymphedema detection, a growing body of work demonstrates the protective effects of ILR. From the pioneering work by Boccardo et al. in 2009 and his introduction of Lymphatic Microsurgical Preventive Healing Approach (LYMPHA) using an intussusception-type end-to-end microanastmosis, to the first randomized control trial by Coriddi in 2023, which importantly employed relative upper extremity volume change as an outcome measure to circumvent the confounding effects of body size and BMI, the current literature supports ILR following ALND in the prevention of BCRL. Collaboration between the oncologic breast surgeon and reconstructive microsurgeon are central to the success of ILR. Critical components for operative success include preoperative and intraoperative lymphatic mapping, preservation of suitable venous targets, availability of supermicrosurgical instruments and sutures, as well as aptitude with a variety of microsurgical anastomotic techniques.

Background and Objectives: Lymphedema is one of the most important morbid complications of modified radical mastectomy (MRM) surgery. It can cause limb movement restriction and psychosocial deformities in some patients. This study aimed to determine and compare the physiological and pathological changes that develop in the axillary venous structures in patients who underwent axillary lymph node dissection (ALND) and sentinel lymph node biopsy (SLNB). Materials and Methods: Patients diagnosed with breast cancer who underwent MRM and breast-conserving surgery (BCS) plus SLNB between 2017 and 2022 were retrospectively examined. The patients’ operation side and contralateral axillary vein diameter and the difference between them, axillary vein flow rate and the difference between them, axillary vein wall thickness and the difference between them, severity of lymphedema, extremity joint restriction examination, and the Nottingham Health Profile (NHP) data were recorded. The relationship of these parameters with the lymph node dissection width and radiotherapy was analyzed. Results: Fifty-eight patients in total were included in the study. In the distribution of lymphedema and lymphedema severity according to ALND groups, there is a statistically significant difference (p < 0.001). A statistically significant difference was determined in the distribution of the difference in the axillary vein blood flow rate and axillary vein diameter difference between the two arms according to the lymph node dissection groups. In the distribution of physical therapy and rehabilitation scales according to the lymph node dissection groups, a significant difference was found in the disabilities of the arm, shoulder, and hand (DASH), shoulder flexion restriction variables, and NHP sleep variables (all p < 0.001). Conclusions: This study demonstrated that ALND leads to more pronounced physiological and pathological changes in axillary venous structures—including increased vein wall thickness, altered flow rates, and diameter differences—compared to SLNB combined with breast-conserving surgery. These changes may be attributed to lymphovenous disruption and postoperative edema. Furthermore, radiotherapy appears to contribute to these changes, though to a lesser extent than ALND. Therefore, SLNB followed by radiotherapy may be preferable in eligible patients to reduce postoperative complications such as lymphedema, joint restriction, and sleep disturbances. Full article

Axillary lymph node dissection (ALND), although increasingly less necessary, is still required in specific breast cancer surgery scenarios, such as cases with a high axillary tumor burden. However, traditional practices are being reassessed due to the associated morbidity and impacts on recovery. This review explores five critical and controversial innovations in ALND: (1) same-day discharge, (2) omission of surgical drains, (3) application of fibrin sealants, (4) minimally invasive techniques, and (5) their collective influence on quality of life (QoL). Same-day discharge has proven to be safe and cost-effective, increasing patient satisfaction without raising complication rates. The omission of drains, while slightly increasing seroma volumes, is linked to shorter hospital stays and fewer complications. The use of fibrin sealants shows promising results in reducing the seroma volume and duration, expediting recovery, although their routine use remains under debate. Minimally invasive and endoscopic techniques reduce morbidity and improve cosmetic outcomes while maintaining oncological safety. Quality of life (QoL) is essential in the evaluation of breast cancer treatment and is evaluated using tools such as EORTC QLQ-C30, QLQ-BR23, and FACT-B, SF-36, which assess physical, emotional, and psychosocial recovery. Innovations in ALND seem to improve QoL by minimizing pain, increasing arm function, and reducing psychological stress, underscoring the importance of patient-centered strategies. Although axillary lymphadenectomy increases arm morbidity compared to sentinel node biopsy, its overall impact on quality of life appears limited, likely due to the overlapping effects of systemic therapies and breast surgery.

Accurate lymph node staging is crucial for both prognosis (in the event of early-stage disease) and treatment (for local control of disease) in patients with breast cancer. Sentinel lymph node biopsy (SLNB) has been studied in numerous international trials, showing that it allows about 70% of axillary lymph node dissection (ALND) to be avoided and thus significantly reduces the morbidity associated with ALND. SLNB represents a necessary step in the diagnostic algorithm for breast neoplasms because the surgical treatment for breast cancer has become progressively less invasive. We present a case of a 70-year-old woman with multicentric breast cancer (MBC) treated by surgery at “Cuza Vodă” Women’s University Hospital, Iassy, Romania. In this case, only the ultrasonography established the diagnosis of left MBC with certainty. Conclusion: The detection of sentinel lymph nodes (SLNs) for MBC must be indicated. In this type of cancer, SLNB is accurate and practical, with sufficient quality control and interdisciplinary collaboration between surgical, nuclear medicine, and pathology units. Lymphoscintigraphy allows the patient to avoid axillary clearance surgery if the sentinel node is negative for metastatic disease. The variability of Ki67, PR, HER2, and ER status supports the idea that all individual foci should be tested in MBC cases to provide the best management and prognosis. Full article

Breast cancer-related lymphedema (BCRL) is the most common cause of secondary lymphedema in the Western world and occurs in up to one-third of breast cancer survivors following axillary lymph node dissection (ALND). Compression of the affected limb is a mainstay of therapy. Surgical management of BCRL involves excision of excess fibroadipose tissue and physiologic procedures to improve fluid retention in the limb. Once lymphedema is established, the inflammatory cascade and fibrosis render the disease hard to reverse. The purpose of this review is to elucidate existing management strategies for prevention of breast cancer-related lymphedema. A literature search was conducted using PubMed, Ovid, Embase, and Scopus. Articles that included management strategies for prevention of BCRL were selected for review. Immediate lymphatic reconstruction (ILR) is a microsurgical technique that connects disrupted axillary lymphatic vessels to nearby veins by lymphovenous anastomoses at the time of ALND and has been shown to reduce rates of lymphedema from 30% to 4–12%. BCRL remains incurable. Immediate lymphatic reconstruction has emerged as a preventative strategy to reduce rates of lymphedema in breast cancer patients. Full article

Background: Implant-based breast reconstruction (IBBR) is a widely adopted technique following mastectomy in breast cancer patients. However, the impact of chemotherapy type and duration on the development of capsular contracture remains unclear. Methods: This nationwide, retrospective, cohort study used Health Insurance Review and Assessment Service data to identify breast cancer patients who received chemotherapy and underwent immediate IBBR between January 2015 and December 2018. Follow-up continued until January 2024, with a median follow-up of 5.2 years. A total of 4303 patients (direct-to-implant [DTI], n = 2083; tissue expander insertion [TEI], n = 2220) were included. Results: Chemotherapy type and duration were not significantly associated with capsular contracture risk in either the DTI or TEI groups. In the DTI cohort, no significant difference in contracture incidence was found between neoadjuvant and adjuvant chemotherapy before or after matching (p = 0.056 and p = 0.121, respectively). In the TEI cohort, an initially significant difference (p = 0.019) was no longer observed after matching (p = 0.213). Similarly, chemotherapy duration (≤12 weeks vs. >12 weeks) did not impact contracture risk in either cohort. Multivariate analysis identified age, radiotherapy, lymphedema, and axillary lymph node dissection (ALND) as independent risk factors for contracture (p < 0.005). Comorbidities, such as diabetes and autoimmune diseases, also showed no significant association with contracture risk. Conclusions: These findings suggest that chemotherapy decisions should not be guided by contracture concerns. Instead, optimizing reconstruction outcomes should focus on modifiable factors, such as radiotherapy, lymphedema, and ALND. Full article

The ACOSOG Z0011 and IBCSG 23-01 trials demonstrated that axillary lymph node dissection (ALND) offers no prognostic benefit in breast cancer patients with clinically negative axillae and low disease burden (one to two positive nodes) on sentinel lymph node biopsy (SLNB). However, uncertainty remains regarding the management of patients with clinically negative axillae (cN0) who are found to have suspicious lymph nodes on imaging that are subsequently confirmed positive by biopsy. The current practice often directs these patients to upfront ALND, potentially exposing them to unnecessary surgical morbidity. This study aimed to assess the role of axillary ultrasound in predicting high axillary nodal burden and guiding surgical management. Using the Alberta Cancer Registry, we identified 107 cN0 breast cancer patients from 2010 to 2017 who underwent preoperative axillary ultrasound with positive biopsy followed by ALND. Our findings reveal that 42% of these patients had low axillary nodal burden on final pathology, meeting Z0011 criteria, and might potentially have avoided ALND. Furthermore, axillary ultrasound findings were not predictive of high axillary burden. These results highlight that many patients undergoing upfront ALND based on positive ultrasound-guided biopsy could benefit from SLNB alone. This supports the 2023 NCCN guidelines advocating for more selective use of ALND to minimize overtreatment and associated morbidity. Full article

Background: Current international guidelines recommend omitting axillary lymph node dissection (ALND) based on sentinel lymph node biopsy (SLNB) in early-stage breast cancer patients. However, the evolving landscape of axillary management highlights the need to balance diagnostic accuracy with minimizing invasiveness. The possibility of omitting SLNB itself should also be considered. Methods: In this study, we have evaluated the feasibility of omitting SLNB in a total of 1044 clinically node-negative (cN (−)) breast cancer patients whose SLN status was determined by histopathology and one-step nucleic acid amplification (OSNA) after SLNB. We also analyzed SLN-positive cases to explore the association between non-SLN (NSLN) metastatic status and various biomarkers. We predicted the metastatic status of NSLNs based on patient data using a nomogram and further assessed the prevalence of macro- and micro-metastatic SLN, along with the NSLN status in SLNB cases. Results: Of the 644 cN (−) cases, approximately 70% of SLN-positive cases were NSLN negative, suggesting that ALND could be omitted. SLN (+) was detected approximately 7% more often by OSNA than by histopathology, suggesting that OSNA detection may be an overdiagnosis. Although NSLN-positive cases represented only 5.9% of the 581 cN (−) cases and, therefore, ALND could be omitted, it may be difficult to omit the SLNB itself as the SLN macro-metastasis was 12.5%. Biomarker analysis showed a significant correlation between total tumor load and metastatic SLN copy number with NSLN metastatic status. Based on these tumor characteristics, the nomogram predicted NSLN-positive rates very well. Conclusions: Thus, omitting SLNB itself carries the risk of missing high-frequency macro-metastatic SLN-positive cases and losing important SLN-related information that can predict NSLN metastases. Therefore, SLNB, which provides not only SLN status but also NSLN metastases, is necessary for reassurance in omitting ALND. Full article

Background: Neoadjuvant therapy (NAT) plays a crucial role in breast cancer (BC) management by enabling tumor and nodal downstaging. While axillary lymph node dissection (ALND) remains the standard for patients with residual nodal disease after NAT, its prognostic benefit is debated. Identifying predictors of high-burden residual axillary disease may guide treatment intensification and surgical de-escalation strategies. Methods: We retrospectively analyzed 262 BC patients treated with NAT followed by ALND between 2006 and 2023. Patients were stratified into low- (ypN0-mi-1) and high-burden (ypN2-3) residual axillary disease groups. Univariate and multivariate logistic regression analyses were performed to identify independent predictors of high-burden residual disease. Results: High-burden residual axillary disease was observed in 35.9% of patients. Baseline cN+ status (OR = 7.697, p = 0.013), HR+/HER2− subtype (OR = 3.945, p = 0.003), and larger post-NAT tumor size (OR = 1.043, p < 0.001) were independent predictors. Conclusions: Identifying patients at risk of high-burden residual axillary disease is essential to optimize neoadjuvant strategies. Increasing axillary pathological complete response may reduce the need for ALND, minimizing surgical morbidity without compromising oncological outcomes. Full article

Despite advancements in breast cancer surgery, the decision-making process for axillary treatment remains complex, necessitating new predictors like the tumor size to Ki67 proliferation index ratio. Intraoperative examination of the sentinel lymph node is performed to reduce the risk of a secondary surgery. Several studies have demonstrated that even in the presence of moderate nodal involvement, local disease control can be achieved by omitting axillary lymph node dissection (ALND). The aim of our retrospective study is to compare patients subjected to sentinel lymph node biopsy (SNLB) with or without intraoperative evaluation. This study included patients with breast cancer who underwent breast-conserving surgery and SNLB. Of the 551 patients, 333 (60.4%) underwent an SNLB intraoperative evaluation (SLNB-IE), while 218 (39.6%) underwent sentinel lymph node dissection diagnostic evaluation (SLNB-DE). Our analysis revealed that the tumor size to Ki67 ratio is an independent predictive factor for axillary tumor burden, suggesting its utility in surgical decision-making. A secondary ALND was performed in 2 (0.6%) vs. 7 (2.8%), p = 0.032, and in 1 (0.4%) vs. 4 (2.1%), p = 0.171, excluding patients with T ≥ 2. Surgical time was significantly shorter (p > 0.001) in the SLNB-DE group. According to a multivariate analysis, lesion dimension (OR 1.678; 95%CI 1.019–2.145; WALD:7.588; p = 0.006) and the ratio of lesion dimension to the Ki67 proliferation index (OR 0.08; 95%CI 0.011–0.141; WALD:11.004 p = 0.001) were both predictive factors for a higher axillary tumor burden. A value of 0.425, which is the ratio of tumor dimension to the Ki67 proliferation index, was identified as a predictor of tumor burden in the axilla (sensitivity, 78%; specificity, 87.5%). Intraoperative evaluation of SNLB may be omitted but could be considered in potential candidates for cyclin inhibitor and cN0 therapy with a higher ratio of tumor dimension to the Ki67 proliferation index in order to avoid secondary surgery.

Background/Objectives: Breast cancer-related lymphedema (BCRL) is a chronic complication of breast cancer treatment, leading to physical and psychological morbidity. While widely studied globally, the prevalence and risk factors for BCRL in Israeli patients remain unexplored. This study’s objectives were to determine the prevalence of BCRL in Israeli women treated for breast cancer, validate the Hebrew-translated Norman Questionnaire (NQ) for BCRL screening, and identify risk factors associated with the condition. Methods: A single-center study was conducted at Tel Aviv Sourasky Medical Center, including 181 patients who underwent unilateral axillary lymph node interventions between 2015 and 2018. Participants completed the Hebrew-translated NQ, which was validated through clinical evaluation and circumference-based volume measurements in a subset of 20 patients. Prevalence rates and risk factors were analyzed using multivariate modeling. Results: The prevalence of BCRL was 20%, with rates varying by procedure: 8.9% for sentinel lymph node biopsy, 19.6% for lymph node sampling, and 37.5% for axillary lymph node dissection (ALND). Of the 35 patients with BCRL, only 14% had been previously diagnosed. Risk factors included ALND (OR = 97.31), a higher lymph node excision count (OR = 0.81), and referral to physiotherapy (OR = 133.50). The Hebrew NQ demonstrated strong validity (rs = 0.852; p < 0.001). Conclusions: This is the first study to estimate BCRL prevalence in Israeli women, highlighting underdiagnosis and the need for improved early detection. The Hebrew NQ is a reliable screening tool, enabling timely referral and intervention. Early diagnosis is crucial for optimizing treatment outcomes and improving the quality of life of BCRL patients.

Breast cancer is one of the most common cancers diagnosed in both countries with high and low levels of socio-academic development. Routine, regular screening tests being introduced in an increasing number of countries make it possible to detect breast cancer at an early stage of development, as a result of which the trend in the incidence of metastatic breast cancer has been decreasing in recent years. The latest guidelines for the treatment of this tumor do not recommend axillary dissection, which limits the need for rapid assessment of the nodes during surgery. Regardless of the progression of the disease, lymph node biopsy and their analysis is one of the most common diagnostic methods for detecting metastases. Systems using one-step amplification of nucleic acids have been present in the diagnosis of breast cancer for nearly 20 years. The one-step nucleic acid amplification (OSNA) test semi-quantitatively detects the number of cytokeratin 19 mRNA copies, a well-known tumor marker, which can be used to infer the presence of metastases in non-sentinel lymph nodes (SLN). Aim: OSNA is a widely used molecular method for SLN, intra-, or postoperative analysis. Its high accuracy has been proved over the years in clinical use. In this review, we checked current state of this technology and compared it to its competitors in the field of breast cancer diagnosis in the era of Axillary Lymph Nodes Dissection (ALND) importance decrease with intention to foresee its further potential use. Objectives: To evaluate OSNA current place in breast cancer diagnosis and treatment we compared OSNA to other lymph node assessing methods. We based our review on original articles and metanalyses published in the last decade. The research was conducted with PubMed, Science Direct, Google Scholar, and NCBI databases. The collected data allowed us to assess the accuracy of OSNA, its cost effectiveness, and its application in other cancers. Results: Regardless of the progression of the disease, a lymph node biopsy and its analysis constitutes one of the most common diagnostic methods for detecting metastases. The OSNA method is characterized by high sensitivity and specificity, and its predictive value has been confirmed by many studies over the years. While its cost effectiveness is still a matter of discussion, this method has been tested more thoroughly than other new lymph nodes assessing technologies. Conclusions: Despite the emergence of competing methods, this test is still widely used as a routine intraoperative examination of lymph nodes. Research carried out in recent years has proved its effectiveness in the diagnosis of other cancers, in the research field, and as a provider of additional data for prognosis improvement.

Background: In the current era of targeted axillary dissection (TAD), there are still cases where axillary lymph node dissection (ALND) is indicated, but histopathological examination confirms the regression of nodal metastases (ypN0). In this situation, ALND may represent undesirable overtreatment. Methods: A retrospective study at the Comprehensive Cancer Centre was conducted based on a prospectively maintained database. Patients who underwent surgery after neoadjuvant chemotherapy (NAC) between 2020 and 2023 were selected, specifically those for whom ALND was directly indicated after NAC. Subsequently, clinical–pathological characteristics were compared between cases with ypN0 and those with persistent metastases (ypN+). The reasons for indicating ALND in ypN0 cases were extracted from the medical records. Results: ALND was indicated in 118 cases across 117 patients, of which ypN0 was observed in 44 cases (37%). There were significantly more ypN0 cases for inflammatory carcinomas (68%), the non-luminal HER2-positive phenotype (76%), and carcinomas with histopathological regression of the primary tumor (76%) or the persistence of only the non-invasive component of ypTis (67%). Typical reasons for ALND in ypN0 cases included inflammatory carcinoma (n = 13, 29.5%), locally advanced carcinoma (n = 5, 11.4%), occult carcinoma (n = 2, 4.5%), or persistent lymphadenopathy on ultrasound examination after NAC, especially in the tumor phenotypes HER2-positive and triple-negative breast cancer (TNBC) (n = 8, 18.2%). Conclusions: Through real-world evidence data analysis, subgroups of breast cancer patients treated with NAC were identified who may experience surgical overtreatment in the axilla. These include patients with inflammatory carcinoma, locally advanced carcinoma, occult carcinoma, or patients with persistent lymphadenopathy on US examination after NAC, particularly in the tumor phenotypes HER2-positive and TNBC.

Objectives: To evaluate the neoadjuvant chemotherapy (NACTx) process in breast cancer (BC), its significant treatment-related adverse events (trAEs), tumor clinical response rates, and surgical and pathological outcomes, and to analyze factors influencing cavity shaving and axillary lymph node dissection (ALND) following sentinel lymph node biopsy (SLNB). Methods: A comprehensive retrospective study was conducted at a single center on patients who received NACTx for BC between 2015 and 2021. Results: Medical records of 242 patients were reviewed. Approximately one-fifth encountered grade ≥ 3 trAEs (21.5%), leading 3.3% to discontinue chemotherapy. Anthracycline cardiotoxicity (2.2%) caused one death (mortality rate = 0.4%). For clinical response and surgical and pathological outcomes, 229 patients were eligible. Clinical progression occurred in 3.9% of the patients (14% in triple-negative BC, p = 0.004). Breast-conserving surgery (BCS) was performed in 55% of the patients. There was no significant difference between the type of breast surgery (BCS vs. mastectomy) and molecular subtype, histology, tumor size, or tumor’s pathological response degree. Cavity shaving was required in one-fifth of the patients who underwent BCS (n = 134) due to an invasive tumor at the surgical margin (SM). Tumor histology (invasive ductal vs. invasive lobular carcinoma; OR: 4.962, 95% CI 1.007–24.441, p = 0.049) and tumor SUVMax value (OR: 0.866, 95% CI 0.755–0.993, p = 0.039) had significant independent efficacy on SM positivity. Initially, 75% underwent SLNB, but nearly half of them needed ALND. ALND rates were significantly higher in the luminal A and LB-HER2(−) groups (87% vs. 69%) than in the HER2(+) and TN groups (43% to 50%) (p = 0.001). All luminal A patients and those with lobular histology required ALND after SLNB, but no patients in the HER2-enriched group required ALND. ER positivity and higher PR expression levels were associated with an increased need for ALND after SLNB, whereas HER2 positivity and higher SUVMax values of LN(s) were associated with a significantly reduced need for ALND. About 27% of the patients achieved overall pCR. No pCR was achieved in the LA group. Conclusions: The BC NACTx process requires close monitoring due to severe AEs and disease progression. NACTx decisions must be made on experienced multidisciplinary tumor boards, considering tumor characteristics and expected targets. Full article

Male breast cancer (MBC) is a rare disease, accounting for less than 1% of all breast cancer cases. Sentinel lymph node biopsy (SLNB) has emerged as a less invasive alternative to axillary lymph node dissection (ALND) for axillary staging in breast cancer, offering reduced morbidity and comparable accuracy. However, the application of SLNB in MBC remains underexplored, with limited male-specific data and treatment protocols often extrapolated from female breast cancer studies. Available evidence suggests that SLNB in men demonstrates high diagnostic accuracy, with low false-negative rates and a high sentinel lymph node identification rate. Despite this, there is ongoing debate about its long-term impact on clinical outcomes, particularly for patients with sentinel node metastasis, where ALND may still provide superior survival outcomes in some cases. Predictive tools are being developed to identify better patients who may benefit from SLNB alone, potentially reducing the need for more invasive procedures. As the role of SLNB continues to evolve in MBC management, further prospective research is needed to refine its application and assess its long-term oncologic outcomes. Full article
