RESUMO

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.

RESUMO

Immediate lymphatic reconstruction (ILR) is recognized as a surgical approach used to reduce the risk of developing secondary lymphedema, and evidence demonstrating the efficacy of ILR is favorable. Our Lymphatic Center has become a centralized location offering ILR for the risk-reduction in breast cancer-related lymphedema (BCRL) in New England. Over the course of our experience, we made several modifications and adapted our approach to enhance the operative success of this procedure. These include advancements in our use of indocyanine green (ICG) imaging to identify baseline lymphatic anatomical variation, utilization of fluorescein isothiocyanate for lymphatic vessel visualization, application of the lymphosome concept to guide arm injection sites, verification of anastomotic patency (using ICG), localization of reconstruction to guide radiation therapy, incorporation of intraoperative tools to facilitate better anatomic visualization of the axilla, and addition of a lower extremity vein graft to mitigate venous-related complications. Collecting information from each surgery in a standardized manner, including intraoperative lymphatic channel measurements, and deploying clips for possible future radiation exposure, enables future studies on ILR patient outcomes. In this contribution, we aimed to share our institutional modifications with the surgical community to facilitate further adoption, conversation, and advancement of ILR for the risk-reduction in BCRL.

RESUMO

OBJECTIVE: We describe the feasibility and short-term outcome of our surgical technique to repair the lymph vessel disruption directly after axillary lymph node dissection during breast cancer surgery. This procedure is called immediate lymphatic reconstruction to prevent breast cancer treatment-related lymphedema (BCRL), which frequently occurs after axillary lymph node dissection. The surgical technique consisted of lymphaticovenous anastomosis (LVA) or lymphaticolymphatic anastomosis. We named the procedure lymphatic bypass supermicrosurgery (LBS). METHODS: This study used a retrospective cohort design of patients with breast cancer between May 2020 and February 2023. LBS was performed by making an intima-to-intima coaptation between afferent lymph vessels and the recipient's veins (LVA) or efferent lymph vessels lymphaticolymphatic anastomosis. RESULTS: A total of 82 patients underwent lymphatic bypass. The mean age of patients was 50 ± 12 years, and most had stage III breast cancer (n = 59 [72%]). LVA was the most common type of lymphatic bypass (94.6%). The median number of LVA was 1 (range, 1-4) and 1 (range, 1-3) for lymphaticolymphatic anastomosis. The median follow-up time was 12.5 months (range, 1-33 months). The 50 patients who had postoperative indocyanine green lymphography described arm dermal backflow stage 0 in 20 (40%), stage 1 in 19 (38%), stage 2 in 2 (4%), and stage 3 in 9 (18%) cases. The proportion of BCRL was 11 (22%), and subclinical lymphedema was 19 (38%) in this period. Most cases were in stable subclinical lymphedema (10, 58.8%). The 1-year and 2-year BCRL rates were 14% (95% confidence interval, 4%-23.9%) and 22% (95% confidence interval, 10.1%-33.9%), respectively. CONCLUSIONS: Along with the emerging immediate lymphatic reconstruction, LBS is a feasible supermicrosurgery technique that may have a potential role in BCRL prevention. A randomized controlled study would confirm the effectiveness of the technique.

RESUMO

Breast cancer-related lymphedema (BCRL) following axillary lymph node dissection (ALND) is a life-altering sequela for patients and a challenging problem for their surgeons. In order to prevent BCRL, immediate lymphatic reconstruction (ILR) is a surgical technique that has been devised to restore lymphatic drainage to the operative limb. Although ILR is becoming popular in the literature, we have identified several challenges within our own ILR research, including a lack of a clear definition of lymphedema, a lack of common outcome measures and possible alteration of the natural history of lymphedema through early compression therapy. Given these challenges, we must move forward with caution, while striving to develop clear and universally agreed upon definitions and outcomes, so that we can advance the body of evidence in support of ILR.

RESUMO

El linfedema (LE) es una de las secuelas más graves e incapacitantes secundarias al tratamiento en el cáncer de mama debido a las limitaciones funcionales, implicaciones estéticas y riesgo de infección que conlleva. Se estima que entre el 29 y 39% de las pacientes que se sujetan a una linfadenectomía axilar desarrollan LE, frente a entre 5 y 7% de los que casos que se realiza una biopsia selectiva de ganglio centinela. Para intentar reducir su incidencia, se ha desarrollado el mapeo axilar inverso. El objetivo de esta técnica es diferenciar las distintas vías de drenaje linfático axilar y del brazo mediante la inyección de un colorante azul en el brazo ipsilateral, para poder respetar los linfáticos que drenan la extremidad superior durante la disección linfática axilar. Otra posibilidad es usar verde de indocianina y así combinar el procedimiento de mapeo axilar inverso con el trazador dual estándar en la biopsia selectiva de ganglio centinela. Gracias a la microcirugía se han desarrollado técnicas como la anastomosis linfático-venosa para la prevención secundaria de LE, de manera que los linfáticos aferentes del brazo se pueden redirigir a ramas colaterales de la vena axilar para restaurar el flujo linfático fisiológico. Este procedimiento es más eficaz en las etapas precoces de LE. En los últimos años se está llevando a cabo la técnica LYMPHA, que consiste en anastomosar los vasos linfáticos del brazo a una rama colateral de la vena axilar en el momento de la disección ganglionar. Esta se ha demostrado útil en la prevención primaria de LE y en la reducción de complicaciones tempranas. (AU)


Lymphoedema (LE) is one of the most serious and disabling sequelae secondary to breast cancer treatment due to the functional limitations, cosmetic implications and risk of infection it entails. Twenty-nine to thirty-nine per cent of patients who undergo axillary lymphadenectomy (AL) are estimated to develop LE, compared to 5-7% in those who undergo selective sentinel lymph node biopsy (SLNB). In an attempt to reduce its incidence, Reverse Axillary Mapping (ARM) has been developed. The aim of this technique is to differentiate the different axillary and arm lymphatic drainage pathways by injecting a blue dye into the ipsilateral arm, in order to respect the lymphatics draining the upper extremity during axillary lymphatic dissection. Another possibility is to use indocyanine green and thus combine the ARM procedure with the standard dual tracer in SLNB. Thanks to microsurgery, techniques such as lymphatic-venous anastomosis (LVA) have been developed for secondary prevention of lymphoedema, so that afferent lymphatics in the arm can be redirected to collateral branches of the axillary vein to restore physiological lymphatic flow. In recent years, the LYMPHA technique, which involves anastomosing the lymphatic vessels of the arm to a collateral branch of the axillary vein at the time of lymph node dissection, has been implemented. This has been shown to be useful in the primary prevention of LE and in the reduction of early complications. (AU)

RESUMO

Immediate lymphatic reconstruction (ILR) at the time of axillary lymph node dissection (ALND) has become increasingly utilized for the prevention of breast cancer related lymphedema. Preoperative indocyanine green (ICG) lymphography is routinely performed prior to an ILR procedure to characterize baseline lymphatic anatomy of the upper extremity. While most patients have linear lymphatic channels visualized on ICG, representing a non-diseased state, some patients demonstrate non-linear patterns. This study aims to determine potential inciting factors that help explain why some patients have non-linear patterns, and what these patterns represent regarding the relative risk of developing postoperative breast cancer related lymphedema in this population. A retrospective review was conducted to identify breast cancer patients who underwent successful ILR with preoperative ICG at our institution from November 2017-June 2022. Among the 248 patients who were identified, 13 (5%) had preoperative non-linear lymphatic anatomy. A history of trauma or surgery of the affected limb and an increasing number of sentinel lymph nodes removed prior to ALND appeared to be risk factors for non-linear lymphatic anatomy. Furthermore, non-linear anatomy in the limb of interest was associated with an increased risk of postoperative lymphedema development. Overall, non-linear lymphatic anatomy on pre-operative ICG lymphography appears to be a risk factor for developing ipsilateral breast cancer-related lymphedema. Guided by the study's findings, when breast cancer patients present with baseline non-linear lymphatic anatomy, our institution has implemented a protocol of prophylactically prescribing compression sleeves immediately following ALND.

RESUMO

OBJECTIVE: To conduct a randomized controlled trial (RCT) on the efficacy of immediate lymphatic reconstruction (ILR) for decreasing the incidence of breast cancer-related lymphedema (BCRL) after axillary lymph node dissection (ALND). BACKGROUND: Despite encouraging results in small studies, an appropriately powered RCT on ILR has not been performed. METHODS: Women undergoing ALND for breast cancer were randomized in the operating room 1:1 to either ILR, if technically feasible, or no ILR (control). The ILR group underwent lymphatic anastomosis to a regional vein using microsurgical techniques; control group had no repair and cut lymphatics were ligated. Relative volume change (RVC), bioimpedance, quality of life (QoL), and compression use were evaluated at baseline and every 6 months postoperatively up to 24 months. Indocyanine green (ICG) lymphography was performed at baseline and 12 and 24 months postoperatively. The primary outcome was the incidence of BCRL, defined as ≥10% RVC from baseline in the affected extremity at 12-, 18-, or 24-month follow-up. RESULTS: Of 72 patients randomized to ILR and 72 to control from January 2020 to March 2023, our preliminary analysis includes 99 patients with 12-month follow-up, 70 with 18-month follow-up, and 40 with 24-month follow-up. The cumulative incidence of BCRL was 9.5% in the ILR group and 32% in the control group ( P =0.014). The ILR group had lower bioimpedance values, decreased compression usage, better lymphatic function on ICG lymphography, and better QoL than the control group. CONCLUSIONS: Preliminary results of our RCT show that ILR after ALND decreases BCRL incidence. Our goal is to finish the accrual of 174 patients with 24-month follow-up.

RESUMO

BACKGROUND: Women with mild breast cancer-related arm lymphedema (BCRAL) mostly receive treatment with compression garments and instructions in self-care to prevent the progression of lymphedema. However, wearing a compression garment may be experienced as negative and may affect health-related quality of life (HRQOL) more than the lymphedema itself. The aim of this study was to investigate if there is a difference in lymphedema-specific HRQOL, between women with mild BCRAL wearing compression garments or not for 6 months. MATERIAL AND METHODS: Participants with mild BCRAL (Lymphedema relative volume <10%) rated their HRQOL by the Lymphedema Quality of Life Inventory (LyQLI), 6 months after diagnosis and being randomized to compression group (CG) or non-compression group (NCG). Both groups received self-care instructions, and the CG was treated with a standard compression garment, compression class 1. Data from 51 women (30 in the CG and 21 in the NCG), were analyzed. RESULTS: Both the CG and the NCG experienced a low negative impact on HRQOL in physical, psychosocial, and practical domains (score <1). However, the CG experienced a higher negative impact on median HRQOL in the practical domain compared to the NCG, 0.23/0.08 respectively, (p = 0.026). In the specific items, more participants in the CG reported a negative impact on HRQOL compared to the NCG in employment activities 23%/0%, (p = 0.032), embarrassment by lymphedema/compression garments 33%/5%, (p = 0.017), feeling discomfort/embarrassment while doing sports and hobbies 30%/5%, (p = 0.034) and having to answer questions about the lymphedema 27%/0% (p = 0.015). CONCLUSION: Overall, the lymphedema-specific HRQOL was high after 6 months in women with mild lymphedema, with only a minor difference between the groups. Some women may however perceive practical and emotional issues with the compression garment. These aspects should be considered in patient education and when planning/evaluating treatment. Trial registration: ISRCTN51918431.

RESUMO

PURPOSE: Breast cancer-related lymphedema (BCRL) represents a lifelong risk for breast cancer survivors and once acquired becomes a lifelong burden. This review summarizes current BCRL prevention and treatment strategies. FINDINGS: Risk factors for BCRL have been extensively studied and their identification has affected breast cancer treatment practice, with sentinel lymph node removal now standard of care for patients with early stage breast cancer without sentinel lymph node metastases. Early surveillance and timely management aim to reduce BCRL incidence and progression, and are further facilitated by patient education, which many breast cancer survivors report not having adequately received. Surgical approaches to BCRL prevention include axillary reverse mapping, lymphatic microsurgical preventative healing (LYMPHA) and Simplified LYMPHA (SLYMPHA). Complete decongestive therapy (CDT) remains the standard of care for patients with BCRL. Among CDT components, facilitating manual lymphatic drainage (MLD) using indocyanine green fluorescence lymphography has been proposed. Intermittent pneumatic compression, nonpneumatic active compression devices, and low-level laser therapy appear promising in lymphedema management. Reconstructive microsurgical techniques such as lymphovenous anastomosis and vascular lymph node transfer are growing surgical considerations for patients as well as liposuction-based procedures for addressing fatty fibrosis formation from chronic lymphedema. Long-term self-management adherence remains problematic, and lack of diagnosis and measurement consensus precludes a comparison of outcomes. Currently, no pharmacological approaches have proven successful. CONCLUSION: Progress in prevention and treatment of BCRL continues, requiring advances in early diagnosis, patient education, expert consensus and novel treatments designed for lymphatic rehabilitation following insults.

RESUMO

INTRODUCTION: Breast cancer-related lymphedema (BCRL) is a chronic condition that can negatively affect the quality of life of breast cancer survivors. Immediate lymphatic reconstruction (ILR) at the time of axillary lymph node dissection is emerging as a technique for the prevention of BCRL. This study compared the incidence of BRCL in patients who received ILR and those who were not amenable to ILR. METHODS: Patients were identified through a prospectively maintained database between 2016 and 2021. Some patients were deemed nonamenable to ILR due to a lack of visualized lymphatics or anatomic variability (eg, spatial relationships or size discrepancies). Descriptive statistics, independent t test, and Pearson χ 2 test were used. Multivariable logistic regression models were created to assess the association between lymphedema and ILR. A loose age-matched subsample was created for subanalysis. RESULTS: Two hundred eighty-one patients were included in this study (252 patients who underwent ILR and 29 patients who did not). The patients had a mean age of 53 ± 12 years and body mass index of 28.6 ± 6.8 kg/m 2 . The incidence of developing lymphedema in patients with ILR was 4.8% compared with 24.1% in patients who underwent attempted ILR without lymphatic reconstruction ( P = 0.001). Patients who did not undergo ILR had significantly higher odds of developing lymphedema compared with those who had ILR (odds ratio, 10.7 [3.2-36.3], P < 0.001; matched OR, 14.2 [2.6-77.9], P < 0.001). CONCLUSIONS: Our study showed that ILR was associated with lower rates of BCRL. Further studies are needed to determine which factors place patients at highest risk of developing BCRL.

RESUMO

PURPOSE: To explore the risk factors for breast cancer-related lymphedema (BCRL) and upper extremity dysfunction (UED) in patients with early breast cancer after modern comprehensive treatment and to compare the toxicity of different treatment strategies. METHODS: From 2017 to 2020, a total of 1369 female patients with pT1-3N0-1M0 breast cancer who underwent adjuvant radiotherapy in our centre were retrospectively reviewed. BCRL and UED were identified by the Norman and QuickDASH questionnaires. The incidence, severity and risk factors for BCRL and UED were evaluated. RESULTS: After a median follow-up of 25 months, a total of 249 patients developed BCRL; axillary lymph node dissection (ALND), increased number of dissected nodes, right-sided and hypofractionated radiotherapy containing RNI were found to be significant risk factors (all p values < 0.05). The sentinel lymph node biopsy (SLNB)+ regional nodal irradiation (RNI) group had a significantly lower BCRL risk than the ALND + RNI group (10.8% vs. 32.5%, HR = 0.426, p = 0.020), while there was no significant difference between ALND vs. ALND + RNI or SLNB vs. SLNB + RNI. A total of 193 patients developed UED, and ALND (p = 0.02) was the only significant risk factor. The SLNB + RNI group had a significantly decreased risk of UED compared with the ALND + RNI group (7.5% vs. 23.9%, HR = 0.260, p = 0.001), and there was no significant difference between SLNB vs. SLNB + RNI or ALND vs. ALND + RNI. CONCLUSION: Aggressive ALND remains the primary risk factor for BCRL and UED while RNI does not. Thus, replacing ALND with tailored radiotherapy would be an effective preventive strategy in early breast cancer patients.

RESUMO

PURPOSE OF REVIEW: Breast cancer-related lymphedema (BCRL) can have a significant impact on breast cancer survivors quality of life. The purpose of this review is to evaluate diagnostic tools for the assessment of BCRL. RECENT FINDINGS: Multiple BCRL diagnostic tools are available, though older diagnostic tools have low sensitivity, limiting the ability for sub-clinical BCRL diagnosis while BIS and perometry have increased sensitivity and the ability to diagnose BCRL sub-clinically. Prospective studies have demonstrated such an approach coupled to early intervention is associated with low rates of chronic BCRL while a recently published randomized trial demonstrated that prospective surveillance with BIS coupled with early intervention reduced rates of chronic BCRL as compared to circumference measurements with compression garments. Prospective and randomized data support the use of prospective surveillance for BCRL. The strongest data available comes from the PREVENT trial and supports prospective BCRL surveillance with bioimpedance spectroscopy coupled to early intervention with a compression sleeve.

RESUMO

OBJECTIVE: To establish a consensus regarding the multidisciplinary prevention of breast cancer-related lymphedema (BCRL), taking into account the expert opinion of professional groups from across the world involved in the identification and treatment of breast cancers. METHODS: International consensus study involving a modified nominal group and Delphi process. A total of 50 preventive strategies representing those used by a range of health disciplines involved in breast cancer care were identified by the nominal group. These strategies were categorised into four subgroups (general recommendations, therapeutic approach, rehabilitation medicine and physiotherapy and dietary recommendations) and presented in survey format to a multidisciplinary panel of experts in a two-round Delphi process. Eleven specialist areas and 15 countries were represented on the panel. RESULTS: Twenty-seven experts responded to both Delphi rounds, and the mean overall agreement after Round 2 was 85.7%. Of the 50 proposed strategies for preventing BCRL, 48 yielded consensus among experts. CONCLUSION: We report an international consensus for the multidisciplinary prevention of BCRL, setting out recommendations aimed at systematising the care of women with breast cancer. The consensus could provide a platform for the development of standardised clinical guidelines.

RESUMO

BACKGROUND: Early diagnosis and compression treatment are important to prevent progression in breast cancer-related arm lymphedema (BCRAL). However, some mild BCRAL can be reversible, and therefore, compression treatment may not be needed. The aim of this study was to investigate the proportion of women with mild BCRAL showing progression/no progression of lymphedema after treatment with or without compression garments, differences in changes of lymphedema relative volume (LRV), local tissue water and subjective symptoms during 6 months. Also, adherence to self-care was examined. MATERIAL AND METHODS: Seventy-five women diagnosed with mild BCRAL were randomized to a compression group (CG) or noncompression group (NCG). Both groups received self-care instructions, and the CG were treated with a standard compression garment (ccl 1). Women in the NCG who progressed in LRV ≥2%, or exceeded 10% dropped out, and received appropriate treatment. The proportion showing progression/no progression of LRV, and changes in LRV was measured by Water Displacement Method. Changes in local tissue water were measured by Tissue Dielectric Constant (TDC), subjective symptoms by Visual Analogue Scale, and self-care by a questionnaire. RESULTS: A smaller proportion of LRV progression was found in the CG compared to the NCG at 1, 2 and 6 months follow-up (p ≤ 0.013). At 6 months, 16% had progression of LRV in the CG, compared to 57% in the NCG, (p = 0.001). Thus, 43% in the NCG showed no progression and could manage without compression. Also, CG had a larger reduction in LRV, at all time-points (p ≤ 0.005), and in the highest TDC ratio, when same site followed, at 6 months (p = 0.025). Subjective symptoms did not differ between the groups, except at 1 month, where the CG experienced more reduced tension (p = 0.008). There were no differences in adherence to self-care. CONCLUSION: Early treatment with compression garment can prevent progression in mild BCRAL. Trial registration: ISRCT nr ISRCTN51918431.

RESUMO

BACKGROUND: Lymphedema is a serious complication of axillary lymph node dissection (ALND) with an incidence rate of 20%. Simplified Lymphatic Microsurgical Preventing Healing Approach (SLYMPHA) is a safe and relatively simple method, which decreases incidence of lymphedema dramatically. Our initial study showed an 88% decrease in clinical lymphedema rate. In the initial study, we used arm circumference measurement for the diagnosis of lymphedema and median follow up was 15 months. The aim of this study was to confirm these results after a long-term follow up period and by using bioimpedance spectroscopy (L-Dex) technology in detecting lymphedema. STUDY DESIGN: All patients, undergoing ALND with or without SLYMPHA between January 2014 and November 2020 were included in the study. Patients with no postoperative L-Dex measurements were excluded. A L-Dex score outside the normal range (±10 L-Dex unit) or ≥10 L-Dex unit increase above patient's baseline was considered as lymphedema. The incidence of lymphedema was compared between patients with and without SLYMPHA. RESULTS: 194 patients were included in the study. 57% of cohort underwent SLYMPHA. Mean follow-up time was 47 ± 37 months. Patients, who underwent SLYMPHA, had a significantly lower rate of lymphedema (16% vs 32%; p = 0.01; OR 0.4 [0.2-0.8]). CONCLUSION: SLYMPHA is a safe and relatively simple method, which continued its efficacy after a long-term follow up period. It should be considered as an adjunct procedure to ALND for all patients during initial surgery.

RESUMO

BACKGROUND: Breast cancer-related lymphedema is a progressive disease that poses tremendous physical, psychosocial, and financial burden on patients. Immediate lymphaticovenular anastomosis at the time of axillary lymph node dissection is emerging as a potential therapeutic paradigm to decrease the incidence of breast cancer-related lymphedema in high-risk patients. METHODS: Eighty-one consecutive patients underwent reverse lymphatic mapping and, when feasible, supermicrosurgical immediate lymphaticovenular anastomosis at the time of axillary lymph node dissection at a tertiary care cancer center. Patients were followed prospectively in a multidisciplinary lymphedema clinic (plastic surgery, certified lymphatic therapy, dietary, case management) at 3-month intervals with clinical examination, circumferential limb girth measurements, and bioimpedance spectroscopy. An institutional control cohort was assessed for the presence of objectively diagnosed and treated breast cancer-related lymphedema. Data were analyzed by a university statistician. RESULTS: Seventy-eight patients met inclusion, and 66 underwent immediate lymphaticovenular anastomosis. Mean follow-up was 250 days. When compared to a retrospective control group, the rate of lymphedema in patients who underwent immediate lymphaticovenular anastomosis was significantly lower (6 percent versus 44 percent; p < 0.0001). Patients with 6-month follow-up treated with combined adjuvant radiation therapy and chemotherapy had significantly greater risk of developing breast cancer-related lymphedema (p = 0.04) compared to those without combined adjuvant therapy. Arborized anastomotic technique had a statistically shorter operative time than end-to-end anastomosis (p = 0.005). CONCLUSIONS: This series of consecutive patients demonstrate a 6 percent incidence of early-onset breast cancer-related lymphedema with immediate lymphaticovenular anastomosis and an increased risk in those undergoing combined adjuvant treatment. These early data represent an encouraging and substantial decrease of breast cancer-related lymphedema in high-risk patients. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

RESUMO

INTRODUCTION: Lymphedema is a pathological condition in which intercellular protein-rich fluid accumulates and leads over time to inflammation, adipose tissue hypertrophy and fibrosis. Secondary lymphedema is caused by injury or blockage of the lymphatic system and the main cause in the Western world is the treatment of a variety of cancers, the main one being breast cancer. Chronic arm edema after breast cancer surgery is a common problem with an estimated incidence of 1 in 5 patients after breast cancer treatment. In this article we review the main risk factors, approaches to reducing the risk of developing lymphedema after treatment for breast cancer and existing treatment protocols for lymphedema including the surgical innovations in this field and our experience in these innovative surgical approaches. To date, 26 physiological surgeries have been performed at the Tel Aviv Medical Center using the microsurgical approach for treating lymphedema. These surgeries had no significant complications and the improvement was observed to be greater in the group of patients with secondary lymphedema. Lymphovenous anastomosis and vascularized lymph node transfer offer promising solutions for the treatment of breast cancer related lymphedema. The introduction of additional techniques and the refinement of these procedures will probably continue to improve the results in the future.

RESUMO

PURPOSE: To determine whether prophylactic use of compression sleeves prevents arm swelling in women who had undergone axillary lymph node dissection for breast cancer surgery. METHODS: Women (n = 307) were randomly assigned to either a compression or control group. In addition to usual postoperative care, the compression group received two compression sleeves to wear postoperatively until 3 months after completing adjuvant treatments. Arm swelling was determined using bioimpedance spectroscopy (BIS) thresholds and relative arm volume increase (RAVI). Incidence and time free from arm swelling were compared using Kaplan-Meier analyses. Hazard ratios (HRs) were estimated from Cox regression models for BIS and RAVI thresholds independently. In addition, time to documentation of the first minimally important difference (MID) in four scales of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and the breast cancer-specific (BR23) questionnaire was analyzed. RESULTS: The HR for developing arm swelling in the compression group relative to the control group was 0.61 (95% CI, 0.43 to 0.85; P = .004) on the basis of BIS and 0.56 (95% CI, 0.33 to 0.96; P = .034) on the basis of RAVI. The estimated cumulative incidence of arm swelling at 1 year was lower in the compression group than the control group on the basis of BIS (42% v 52%) and RAVI (14% v 25%). HRs for time from baseline to the first change of the minimally important difference were not statistically significant for any of the four scales of EORTC QLQ-30 and BR23 questionnaires. CONCLUSION: Prophylactic use of compression sleeves compared with the control group reduced and delayed the occurrence of arm swelling in women at high risk for lymphedema in the first year after surgery for breast cancer.
