Geographic Disparities and Payment Variation for Immediate Lymphatic Reconstruction in Massachusetts.

BACKGROUND: Little is known about practice patterns and payments for immediate lymphatic reconstruction (ILR). This study aims to evaluate trends in ILR delivery and billing practices. METHODS: We queried the Massachusetts All-Payer Claims Database between 2016 and 2020 for patients who underwent lumpectomy or mastectomy with axillary lymph node dissection for oncologic indications. We further identified patients who underwent lymphovenous bypass on the same date as tumor resection. We used ZIP code data to analyze the geographic distribution of ILR procedures and calculated physician payments for these procedures, adjusting for inflation. We used multivariable logistic regression to identify variables, which predicted receipt of ILR. RESULTS: In total, 2862 patients underwent axillary lymph node dissection over the study period. Of these, 53 patients underwent ILR. Patients who underwent ILR were younger (55.1 vs 59.3 years, P = 0.023). There were no significant differences in obesity, diabetes, or smoking history between the two groups. A greater percentage of patients who underwent ILR had radiation (83% vs 67%, P = 0.027). In multivariable regression, patients residing in a county neighboring Boston had 3.32-fold higher odds of undergoing ILR (95% confidence interval: 1.76-6.25; P < 0.001), while obesity, radiation therapy, and taxane-based chemotherapy were not significant predictors. Payments for ILR varied widely. CONCLUSIONS: In Massachusetts, patients were more likely to undergo ILR if they resided near Boston. Thus, many patients with the highest known risk for breast cancer-related lymphedema may face barriers accessing ILR. Greater awareness about referring high-risk patients to plastic surgeons is needed.

The Impact of Obesity on Success of Immediate Lymphatic Reconstruction for Prevention of Breast Cancer-Related Lymphedema.

BACKGROUND: Breast cancer-related lymphedema (BRCL) is a potential sequela of high-risk breast cancer treatment. Preventive treatment with immediate lymphatic reconstruction (ILR) at the time of axillary lymph node dissection (ALND) has emerged as the standard of care; however, there is relatively little known about factors that may contribute to procedural failure. METHODS: A retrospectively maintained, institutional review board-approved study followed patients who underwent ILR at the time of ALND at our tertiary care center between May 2018 and May 2023. Patients who presented for at least one follow-up visit in our multidisciplinary lymphedema clinic met the criteria for inclusion. Patients who developed lymphedema despite ILR and potential contributing factors were further explored. RESULTS: 349 patients underwent ILR at our institution between May 2018 and May 2023. 341 of these patients have presented for follow-up in our multidisciplinary lymphedema clinic. 32 (9.4%) patients developed lymphedema despite ILR. This cohort was significantly more likely to be obese (56% vs 35%, P = 0.04). Multivariate logistic regression demonstrates increased odds of procedural failure in patients with a body mass index (BMI) ≥30 kg/m2 (odds ratio 2.6 [1.2-5.5], P = 0.01). CONCLUSION: These data comment upon our institutions outcomes following ILR. Patients who develop lymphedema despite ILR tend to have a higher BMI, with a significantly increased risk in patients with a BMI of 30 or greater. Consideration of these data is critical for preprocedural counseling and may support a BMI cutoff when considering candidacy for ILR going forward, as well as when optimizing failures for secondary lymphedema procedures.

A study on the safety and efficacy of endoscopic thyroidectomy via axillary approach for the treatment of thyroid cancer.

This study aims to evaluate the safety and efficacy of endoscopic thyroid cancer treatment using an axillary approach. Participants were allocated into 2 groups: one undergoing transaxillary endoscopic surgery and the other, traditional open surgery. We compared intraoperative and postoperative conditions, focusing on parameters such as intraoperative blood loss, duration of surgery, length of postoperative hospitalization, volume of postoperative drainage, number of lymph nodes cleared in the central region, neck pain scores, neck injury indices, cosmetic satisfaction, postoperative complications, and total hospitalization duration. Patients in the endoscopic treatment (ET) group experienced longer surgical times, less intraoperative bleeding, and increased postoperative drainage. These indicators showed significant differences between the groups (P < .05). For the group undergoing endoscopic surgery via the axillary approach, there was a lower neck pain score on the third postoperative day and higher cosmetic satisfaction at 3 months. However, there were no significant differences between the groups in terms of the number of lymph nodes cleared in the central area, and the incidence of complications such as difficulty breathing, difficulty swallowing, hoarseness, and subcutaneous hematoma (P > .05). The axillary approach endoscopic surgery group also showed significantly prolonged surgery times and postoperative hospital stays, with a significant increase in postoperative drainage fluid (P < .05). Concurrently, this technique involved smaller surgical incisions and effectively concealed scars in the armpit, leading to better outcomes in terms of intraoperative bleeding, neck pain scores, and postoperative cosmetic satisfaction. Non-inflatable ET via the axillary approach for treating thyroid cancer demonstrates promising efficacy and safety. It offers additional benefits of minimal pain and enhanced cosmetic outcomes, making it a viable option for clinical adoption and application.

Endoscopic Bilateral Nipple-sparing Mastectomy via a Single Axillary Incision with Immediate Pre-pectoral Implant-based Breast Reconstruction.

Oncoplastic breast surgery, with its focus on improving cosmetic outcomes while maintaining oncological safety, has fundamentally transformed the landscape of breast cancer surgical treatment, giving rise to an array of techniques for breast reconstruction. Nipple-sparing mastectomy (NSM) with immediate implant-based breast reconstruction (IBBR) has emerged as a cornerstone in managing early breast cancer. Aligned with the principles of minimally invasive surgery, recent years have witnessed the widespread integration of endoscopic approaches in breast surgery, encompassing procedures like endoscopic breast-conserving surgery (E-BCS) and endoscopic nipple-sparing mastectomy (E-NSM), among others. Capitalizing on the advantages of inconspicuous and shorter incisions, improved visibility, and the avoidance of radiation therapy, the popularity of E-NSM with IBBR is on the rise. However, conventional E-NSM with IBBR often requires two or more incisions, which can result in suboptimal cosmetic outcomes and even prosthesis loss.This paper presents a comprehensive account of the intricate surgical procedures involved in endoscopic bilateral nipple-sparing mastectomy with immediate pre-pectoral implant-based breast reconstruction. The insights shared are drawn from the collective experience of our institution. Notable benefits associated with the described surgical approach encompass enhanced cosmetic outcomes, improved postoperative quality of life, and enhanced physiological functions attributable to the application of pre-pectoral implant-based breast reconstruction through a single incision.

Current axillary management of patients with early breast cancer and low-volume nodal disease undergoing primary surgery: results of a United Kingdom national practice survey.

PURPOSE: UK NICE guidelines recommend axillary node clearance (ANC) should be performed in all patients with biopsy-proven node-positive breast cancer having primary surgery. There is, however, increasing evidence such extensive surgery may not always be necessary. Targeted axillary dissection (TAD) may be an effective alternative in patients with low-volume nodal disease who are clinically node negative (cN0) but have abnormal nodes detected radiologically. This survey aimed to explore current management of this group to inform feasibility of a future trial. METHODS: An online survey was developed to explore current UK management of patients with low-volume axillary disease and attitudes to a future trial. The survey was distributed via breast surgery professional associations and social media from September to November 2022. One survey was completed per unit and simple descriptive statistics used to summarise the results. RESULTS: 51 UK breast units completed the survey of whom 78.5% (n = 40) reported performing ANC for all patients with biopsy-proven axillary nodal disease having primary surgery. Only 15.7% of units currently performed TAD either routinely (n = 6, 11.8%) or selectively (n = 2, 3.9%). There was significant uncertainty (83.7%, n = 36/43) about the optimal surgical management of these patients. Two-thirds (n = 27/42) of units felt an RCT comparing TAD and ANC would be feasible. CONCLUSIONS: ANC remains standard of care for patients with low-volume node-positive breast cancer having primary surgery in the UK, but considerable uncertainty exists regarding optimal management of this group. This survey suggests an RCT comparing the outcomes of TAD and ANC may be feasible.

A review of surgical and reconstructive techniques for hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is an inflammatory follicular dermatological condition that typically affects the intertriginous and anogenital regions of the apocrine gland-bearing skin. The management of this chronic and recurring disease necessitates a combination of lifestyle changes, medication, and surgical approaches to achieve the best possible outcomes. While medical treatments are recommended for this multimodal disease, surgical therapy, which is the gold standard of treatment for HS, has proven to be the most effective treatment because it provides long-lasting local disease control, reduces the recurrence of lesions, and ensures complete healing of lesions. In the last decade, there has been exponential growth in research into various surgical techniques and reconstructive care, enabling patients to have more surgical options. There is a wide range of surgical management procedures available, such as incision and drainage, deroofing, excisional surgery, carbon dioxide laser therapy, and skin tissue-sparing excision with electrosurgical peeling. Among these surgical procedures, wide surgical excision is the best option since it can eradicate all the affected lesions. Meanwhile, the preferred approach to reconstruction at various anatomical locations remains debatable. Here, we review a variety of surgical treatments and reconstructive techniques for HS, particularly various flap techniques for the axillary, gluteal, and inframammary regions.

Endovascular repair of an abdominal aortic aneurysm with external iliac artery occlusion using VBX as the contralateral leg via axillary delivery: A case report.

RATIONALE: A hostile iliac access route is an important consideration when enforcing endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAA). Herein, we report a case of AAA with unilateral external iliac artery occlusion, for which bifurcated EVAR was successfully performed using a single femoral and brachial artery access. PATIENT CONCERNS: A 76-year-old man who had undergone surgery for lung cancer 4.5 years prior was diagnosed AAA by computed tomography (CT). DIAGNOSIS: Two and a half years before presentation, CT revealed an infrarenal 48 mm AAA, which had enlarged to 57 mm by 2 months preoperatively. CT identified occlusion from the right external iliac artery to the right common femoral artery, with no observed ischemic symptoms in his right leg. The right external iliac artery, occluded and atrophied, had a 1 to 2 mm diameter. INTERVENTION: Surgery was commenced with the selection of a Zenith endovascular graft (Cook Medical) with an extended body length. Two Gore Viabahn VBX balloon expandable endoprosthesis (VBX; W.L. Gore & Associate) were delivered from the right axilla as the contralateral leg. OUTCOMES: CT scan on the 2nd day after surgery revealed no endoleaks. LESSONS: While the long-term results remain uncertain, this method may serve as an option for EVAR in patients with unilateral external iliac artery occlusion.

Reducing axillary surgery in breast cancer / Reduciendo la cirugía axilar en el cáncer de mama

This article provides a brief account of the recent evolution of the highly controversial surgical management of the positive axilla in patients with breast cancer, an issue still open to disparate surgical procedures. This short review highlights the reports that supply the rationale for current trends in reducing the aggressiveness of this surgery and discusses the course of the trials still in progress pointing in the same direction, thus supporting the principle of not performing axillary lymph node dissection for staging purposes alone.(AU)

Este artículo es un breve resumen de la reciente evolución del controvertido tratamiento quirúrgico de la axila en pacientes con cáncer de mama, que sigue estando abierto a procedimientos quirúrgicos demasiado dispares. Esta corta revisión destaca las publicaciones que constituyen la base lógica de las tendencias actuales hacia la reducción de la agresividad quirúrgica y recalca los ensayos clínicos aún en progreso apuntando en esta misma dirección, apoyando así el principio de evitar la linfadenectomía axilar solo por razones de estadiaje.(AU)

Alternative Lymphatic Drainage Pathways in the Trunk Following Oncologic Therapy.

BACKGROUND: Anatomic and functional descriptions of trunk and breast lymphedema following breast cancer treatment are emerging as indicators of lymphatic dysfunction. Indocyanine green-lymphangiography has been instrumental in characterizing this dysfunction in the extremity and can be applied to other regions. Previous work has established a validated Pittsburgh Trunk Lymphedema Staging System to characterize such affected areas. This study aims to identify risk and protective factors for the development of truncal and upper extremity lymphedema using alternative lymphatic drainage, providing implications for medical and surgical treatment. METHODS: Patients undergoing revisional breast surgery with suspicion of upper extremity lymphedema between 12/2014 and 3/2020 were offered lymphangiography. The breast and lateral/anterior trunks were visualized and blindly evaluated for axillary and inguinal lymphatic flow. A linear-weighted Cohen's kappa statistic was calculated comparing alternative drainage evaluation. Binomial regression was used to compute relative risks (RRs). Significance was assessed at alpha = 0.05. RESULTS: Eighty-six sides (46 patients) were included. Twelve sides underwent no treatment and were considered controls. Eighty-eight percent of the noncontrols had alternative lymphatic flow to the ipsilateral axillae (64%), ipsilateral groins (57%), contralateral axillae (20.3%), and contralateral groins (9.3%). Cohen's kappa for alternative drainage was 0.631 ± 0.043. Ipsilateral axillary and contralateral inguinal drainage were associated with reduced risk of developing truncal lymphedema [RR 0.78, confidence interval (CI) 0.63-0.97, P = 0.04; RR 0.32, CI 0.13-0.79, P = 0.01, respectively]. Radiation therapy increased risk of truncal and upper extremity lymphedema (RR 3.69, CI 0.96-14.15, P = 0.02; RR 1.92, CI 1.09-3.39, P = 0.03, respectively). Contralateral axillary drainage and axillary lymph node dissection were associated with increased risk of upper extremity lymphedema (RR 4.25, CI 1.09-16.61, P = 0.01; RR 2.83, CI 1.23-6.52, P = 0.01, respectively). CONCLUSIONS: Building upon previous work, this study shows risk and protective factors for the development of truncal and upper extremity lymphedema. Most prevalent alternative channels drain to the ipsilateral axilla and groin. Ipsilateral axillary and contralateral inguinal drainage were associated with reduced risk of truncal lymphedema. Patients with radiation, axillary dissection, and contralateral axillary drainage were associated with increased risk of upper extremity lymphedema. These findings have important clinical implications for postoperative manual lymphatic drainage and for determining eligibility for lymphovenous bypass surgery.

Seroma control in axillary lymphadenectomy with Glubran 2® without drain. Multicenter, prospective, randomized, clinical trial. GALA-ND study (Glubran, Axillary Lymphadenectomy, Ambulatory, No Drain).

BACKGROUND: Seroma after breast cancer surgery is a frequent entity; therefore, different products have been described in literature with the aim to reduce it. The most studied ones have been the sealants products, being tested with aspirative drains. Symptomatic seroma represents the 19% after axillary lymphadenectomy without drains. The aim of this study is to analyze the effect of a sealant in the seroma control after axillary lymphadenectomy without drains and identify the risk factors related to symptomatic seroma. METHODS: This is a prospective, multicenter, international, and randomized clinical trial. Patients undergoing conservative surgery and axillary lymphadenectomy for breast cancer will be randomized to control group (lymphadenectomy without sealant) or interventional group (lymphadenectomy with sealant Glubran 2®). In any of the study groups, drains are placed. Patients who received neoadjuvant treatment are included. Measurements of the study outcomes will take place at baseline; at 7, 14, and 30 days post-surgery; and at 6-12 months. The primary outcome is symptomatic seroma. Secondary outcomes are seroma volume, morbidity, quality of life, and lymphedema. DISCUSSION: Several studies compare the use of sealant products in axillary lymphadenectomy but generally with drains. We would like to demonstrate that patients who underwent axillary lymphadenectomy could benefit from an axillary sealant without drains and reduce axillary discomfort while maintaining a good quality of life. Assessing the relationship between axillary volume, symptoms, and related risk factors can be of great help in the control of seroma in patients who received breast cancer surgery.

[Preventive axillary lymphovenous anastomoses simultaneously with lymph node dissection in the treatment of breast cancer for prevention of lymphedema of the upper limb (LYMPHA technique)]. / Preventivnoe nalozhenie limfovenoznykh anastomozov v podmyshechnoi oblasti odnomomentno s limfaticheskoi dissektsiei pri lechenii raka molochnoi zhelezy dlya profilaktiki limfedemy verkhnei konechnosti (metodika LYMPHA).

OBJECTIVE: To analyze the effect the LYMPHA technique on the incidence of upper limb lymphedema in patients with breast cancer after complete axillary lymph node dissection. MATERIAL AND METHODS: There were 89 patients with breast cancer and signs of metastatic lesion of axillary lymph nodes who underwent complete axillary lymph dissection. In group 1 (41 patients), the LYMPHA technique was used simultaneously with lymph node dissection; in group 2 (48 patients) - lymph node dissection alone. RESULTS: The follow-up period was 1 year. The LYMPHA technique prolonged surgery and decreased duration of postoperative lymphorrhea. The incidence of upper limb lymphedema was 9.8% and 22.9%, respectively. CONCLUSION: The LYMPHA technique was effective for prevention of upper limb lymphedema after complete axillary lymph node dissection in the treatment of breast cancer.

Separate axillary incision for surgery of axillary lymph node can decrease drain amount and days to drain removal of the breast in direct-to-implant breast reconstruction.

PURPOSE: Sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) can be performed either with a separate axillary incision or through the mastectomy incision. The authors hypothesized that after SLNB or ALND through a single incision, connection of the axilla with mastectomy pocket could increase drainage. This study investigated whether a separate incision decreases drainage amount and duration in implant-based breast reconstruction. METHODS: Medical records of breast cancer patients who underwent nipple-sparing or skin-sparing mastectomy with immediate breast reconstruction with prosthesis from March 2018 to February 2021 in a single tertiary center were reviewed. Demographic data, intraoperative details, and postoperative complications were reviewed. Breast drains were removed if the drain amount was less than 30cc for two consecutive days. Total breast drain amount, duration until removal, and prolonged drainage were compared with multivariate analysis. RESULTS: A total of 206 patients were included in the study, with separate incisions placed in 145 breasts and a single breast incision placed in 70 breasts. Mean duration and amount until drain removal were 12.8 ± 4.9 days and 817 ± 520 cc in the single incision group, respectively, and 9.9 ± 3.1 days and 434 ± 228 cc in the separate incision group, respectively Separate incision placement (p < 0.001), lower mastectomy weight (p < 0.001), and prepectoral plane of insertion (p < 0.001) were significantly associated with less drain amount and duration. None-separate incision placement (p = 0.01) and preoperative radiation therapy (p = 0.023) were significant factors for prolonged drainage. CONCLUSION: Placing a separate incision for axillary surgery during mastectomy and immediate implant-based reconstruction can decrease both drain amount and duration and reduce the risk of prolonged drainage.

Retrospective validation study of an artificial neural network-based preoperative decision-support tool for noninvasive lymph node staging (NILS) in women with primary breast cancer (ISRCTN14341750).

BACKGROUND: Surgical sentinel lymph node biopsy (SLNB) is routinely used to reliably stage axillary lymph nodes in early breast cancer (BC). However, SLNB may be associated with postoperative arm morbidities. For most patients with BC undergoing SLNB, the findings are benign, and the procedure is currently questioned. A decision-support tool for the prediction of benign sentinel lymph nodes based on preoperatively available data has been developed using artificial neural network modelling. METHODS: This was a retrospective geographical and temporal validation study of the noninvasive lymph node staging (NILS) model, based on preoperatively available data from 586 women consecutively diagnosed with primary BC at two sites. Ten preoperative clinicopathological characteristics from each patient were entered into the web-based calculator, and the probability of benign lymph nodes was predicted. The performance of the NILS model was assessed in terms of discrimination with the area under the receiver operating characteristic curve (AUC) and calibration, that is, comparison of the observed and predicted event rates of benign axillary nodal status (N0) using calibration slope and intercept. The primary endpoint was axillary nodal status (discrimination, benign [N0] vs. metastatic axillary nodal status [N+]) determined by the NILS model compared to nodal status by definitive pathology. RESULTS: The mean age of the women in the cohort was 65 years, and most of them (93%) had luminal cancers. Approximately three-fourths of the patients had no metastases in SLNB (N0 74% and 73%, respectively). The AUC for the predicted probabilities for the whole cohort was 0.6741 (95% confidence interval: 0.6255-0.7227). More than one in four patients (n = 151, 26%) were identified as candidates for SLNB omission when applying the predefined cut-off for lymph node-negative status from the development cohort. The NILS model showed the best calibration in patients with a predicted high probability of healthy axilla. CONCLUSION: The performance of the NILS model was satisfactory. In approximately every fourth patient, SLNB could potentially be omitted. Considering the shift from postoperatively to preoperatively available predictors in this validation study, we have demonstrated the robustness of the NILS model. The clinical usability of the web interface will be evaluated before its clinical implementation. TRIAL REGISTRATION: Registered in the ISRCTN registry with study ID ISRCTN14341750.

Pedicled circumflex scapular artery perforator flap with intra-axillary tunneling for axillary defect coverage after surgical excision of hidradenitis suppurativa: A case report and literature review.

Axillary defects represent a rather common issue in plastic surgery practice. Surgical resections related to skin disease are frequent in this region and their extension often requires soft tissue transfer for coverage. In this setting, locoregional pedicled flaps are usually preferred. The nearby tissues offer pliable but still resistant skin, which satisfy the "like-with-like" reconstructive principle. Over the years different procedures have been described for this purpose. Among them, a valuable and often underestimated technique is the circumflex scapular artery perforator flap (CSAP). This technique might be particularly suitable for thin but relatively large defects. Its main advantages are a low donor site morbidity, a very reliable anatomy, and a perforator pedicle able supply a large skin paddle. In the present work, we report the use of a pedicled vertical CSAP flap passed through the axillary canal in order to cover a 9 cm × 7 cm axillary defect after surgical excision of hidradenitis suppurativa resistant to conservative treatment. The perforator-based pedicled presented two branches, which allowed us to harvest safely a large skin paddle, which limited its range of motion. For this reason, we opted for a passage through the axillary canal for the flap inset. The postoperative course was uneventful and full shoulder range of motion was obtained at 3 months follow-up. Despite most of the descriptions of this flap available so far showed its employment for limb's reconstructions, we believe that it is a very useful tool also for locoregional coverage. Moreover, the unconventional passage below the axillary muscles allowed reaching the recipient site even with a shorter pedicle, such as the one encountered in this case.

The Efficacy of Axillary Reverse Mapping for the Prevention of Lymphedema.

BACKGROUND: Lymphedema (LE) is the most notable complication of axillary surgery. The axillary reverse mapping (ARM) technique was created to decrease LE. This study aims to evaluate a single surgeon's experience with ARM in patients undergoing sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) for breast cancer. METHODS: We retrospectively analyzed patients who underwent SLNB or ALND. Tumor characteristics and treatments received were evaluated. Surgical intervention and use of ARM were compared to assess LE rates. A subgroup analysis was also performed of patients who underwent NAC. RESULTS: LE was initially reported in 7.1% (n = 10) of patients; 3.3% (n = 4) with SLNB and 35% (n = 6) with ALND. At initial follow-up, LE was reported 16.4% more often in patients who underwent ALND with no ARM, and 38.8% more often in patients who underwent ALND plus ARM. An increased risk of LE was found in patients treated with ALND (OR = 16.0, P < .001). All patients who underwent ARM were 12.75% more likely to develop LE if they received NAC (P < .05). Patients in the ALND group who also received NAC were more likely to undergo ARM as compared with patients in the SLNB group (P < .01). DISCUSSION: Our study showed that ARM failed to decrease the incidence of LE. Until better surgical outcomes are shown for the prevention of LE using ARM, other approaches should be utilized. However, larger prospective studies are needed to evaluate ARM.

Immediate Lymphatic Reconstruction in 77 Consecutive Breast Cancer Patients: 2-year Follow-up.

BACKGROUND: Breast cancer-related lymphedema (BCRL) is a cyclical, progressive disease that begins at the time of axillary dissection and worsens in the setting of adjuvant oncologic therapies. The paradigm of lymphedema management in these patients is shifting from therapeutic surgeries and decongestive therapy to preventative surgery with immediate lymphatic reconstruction (ILR). METHODS: After institutional review board approval, a prospective database was maintained of all patients undergoing ILR. Patients were excluded if they had preoperative lymphedema or expired during the study period. All ILR were performed by the senior author. A control group was established with standardized physician delivered phone surveys of patients who had axillary dissection for breast cancer (same oncologic surgeon cohort) prior to the implementation of ILR at the same institution. The study and control groups were matched based on history of adjuvant radiation and body mass index. RESULTS: A cohort of patients between 2016 and 2019 with 2 years of follow-up after undergoing ILR (77 patients) were matched with those who did not undergo lymphatic reconstruction (94 patients). The incidence of lymphedema in the study group undergoing ILR was 10% (N = 8). In comparison, the incidence in the cohort who did not undergo lymphatic reconstruction was 38% (N = 36; p < 0.01). Patients with ILR had 92% lower odds of developing lymphedema (p < 0.01). CONCLUSION: ILR can significantly reduce the risk of developing BRCL in high-risk patients at 2 years of follow-up. Patients receiving adjuvant radiation therapy are more likely to develop BCRL after ILR compared with those who do not. Ongoing studies include investigation aimed at identifying patients most at risk for the development of BRCL to help target intervention as well as elucidate factors that contribute to the success of ILR.

Immediate-delayed lymphatic reconstruction after axillary lymph nodes dissection for locally advanced breast cancer-related lymphedema prevention: Report of two cases.

Approximately 60%-70% of breast cancer patients in Indonesia are diagnosed in the locally advanced stage. The stage carries a higher risk of lymph node metastasis which increases susceptibility to lymph obstruction. Hence, breast cancer-related lymphedema (BCRL) could present before axillary lymph node dissection (ALND). The purpose of this case report is to describe immediate-delayed lymphatic reconstructions with lymphaticovenous anastomosis in two subclinical lymphedema cases that present before ALND. There were 51 and 58 years old breast cancer patients with stage IIIC and IIIB, respectively. Both had no arm lymphedema symptoms, but arm lymphatic vessel abnormalities were found during preoperative indocyanine green (ICG) lymphography. Mastectomy and ALND were performed and proceeded with lymphaticovenous anastomoses (LVA) in both cases. One LVA at the axilla (isotopic) was done in the first patient. On the second patient, 3 LVAs at the affected arm (ectopic) and 3 isotopic LVAs were created. The patients were discharged on the second day without complications during the follow-up. The intensity of dermal backflow was reduced, and no subclinical lymphedema progression occurred during 11 and 9 months follow-up, respectively. Based on these cases, BCRL screening might be recommended for the locally advanced stage before cancer treatment. Once diagnosed, immediate lymphatic reconstruction after ALND should be recommended to cure or prevent BCRL progression.

Superparamagnetic iron oxide (SPIO) for axillary mapping in patients with ductal carcinoma in situ undergoing mastectomy: single-institution experience.

PURPOSE: Unnecessary axillary surgery can potentially be avoided in patients with DCIS undergoing mastectomy. Current guidelines recommend upfront sentinel lymph node biopsy during the index operation due to the potential of upstaging to invasive cancer. This study reviews a single institution's experience with de-escalating axillary surgery using superparamagnetic iron oxide dye for axillary mapping in patients undergoing mastectomy for DCIS. METHODS: This is a retrospective single-institution cross-sectional study. All medical records of patients who underwent mastectomy for a diagnosis of DCIS from August 2021 to January 2023 were reviewed and patients who had SPIO injected at the time of the index mastectomy were included in the study. Descriptive statistics of demographics, clinical information, pathology results, and interval sentinel lymph node biopsy were performed. RESULTS: A total of 41 participants underwent 45 mastectomies for DCIS. The median age of the participants was 58 years (IQR = 17; range 25 to 76 years), and the majority of participants were female (97.8%). The most common indication for mastectomy was diffuse extent of disease (31.7%). On final pathology, 75.6% (34/45) of mastectomy specimens had DCIS without any type of invasion and 15.6% (7/45) had invasive cancer. Of the 7 cases with upgrade to invasive disease, 2 (28.6%) of them underwent interval sentinel lymph node biopsy. All sentinel lymph nodes biopsied were negative for cancer. CONCLUSION: The use of superparamagnetic iron oxide dye can prevent unnecessary axillary surgery in patients with DCIS undergoing mastectomy.

Health-related quality of life (HRQoL) after different axillary treatments in women with breast cancer: a 1-year longitudinal cohort study.

PURPOSE: As life expectancy continues to rise, post-treatment health-related quality of life (HRQoL) of breast cancer patients becomes increasingly important. This study examined the one-year longitudinal relation between axillary treatments and physical, psychosocial, and sexual wellbeing and arm symptoms. METHODS: Women diagnosed with breast cancer who received different axillary treatments being axilla preserving surgery (APS) with or without axillary radiotherapy or full axillary lymph node dissection (ALND) with or without axillary radiotherapy were included. HRQoL was assessed at baseline, 6- and 12-months postoperatively using the BREAST-Q and the European Organization for Research and Treatment of Cancer QoL Questionnaire Breast Cancer Module (EORTC QLQ-BR23). Mixed regression models were constructed to assess the impact of axillary treatment on HRQoL. HRQoL at baseline was compared to HRQoL at 6- and at 12-months postoperatively. RESULTS: In total, 552 patients were included in the mixed regressions models. Except for ALND with axillary radiotherapy, no significant differences in physical and psychosocial wellbeing were found. Physical wellbeing decreased significantly between baseline and 6- and 12-months postoperatively (p < 0.001, p = 0.035) and psychosocial wellbeing decreased significantly between baseline and 12 months postoperatively (p = 0.028) for ALND with axillary radiotherapy compared to APS alone. Arm symptoms increased significantly between baseline and 6 months and between baseline and 12 months postoperatively for APS with radiotherapy (12.71, 13.73) and for ALND with radiotherapy (13.93, 16.14), with the lowest increase in arm symptoms for ALND without radiotherapy (6.85, 7.66), compared to APS alone (p < 0.05). CONCLUSION: Physical and psychosocial wellbeing decreased significantly for ALND with radiotherapy compared to APS alone. Shared decision making and expectation management pre-treatment could be strengthened by discussing arm symptoms per axillary treatment with the patient.

Optimising of axillary therapy in breast cancer: lessons from the past to plan for a better future.

In this narrative review, we aim to explore the ability of radiation therapy to eradicate breast cancer regional node metastasis. It is a journey through data of older trials without systemic therapy showing the magnitude of axillary therapy (surgery versus radiation) on cancer control. Considering that both systemic and loco-regional therapies were shown to reduce any recurrence with a complex interaction, our review includes surgical, radiation, and radiobiology consideration for breast cancer, and provide our view of future practise. The aim is to provide information optimise radiation therapy in the era of primary systemic therapy.
