RESUMO

INTRODUCTION: In female patients diagnosed with gynaecological cancer, the main priority is treating cancer itself. However, a significant number of these patients develop lower limb lymphoedema (LLL), with its incidence strongly influenced by the diagnostic cut-off (a difference in leg circumference between both legs of 5% or 10%). LLL significantly impacts patients' quality of life (QoL) due to functional impairment, the daily time investment required for treatment, financial costs and affected body image. Additionally, it increases the risk of cellulitis, often leading to hospitalisation for intravenous antibiotics. Timely recognition and acknowledgement of symptoms are crucial first steps in improving the QoL for these women. LLL is a common and irreversible complication following treatment for gynaecological cancer. Despite its clinical significance, there are limited prospective studies investigating LLL incidence, risk factors, early detection and clinical course in this patient population. Therefore, the objective of this observational cohort study is to investigate the incidence rate of stage 0-1 or stage 2-3 LLL based on the International Society of Lymphology criteria in the first 2 years after gynaecological cancer treatment. The embedded randomised control study (RCT) examines the added value of prophylactic compression garments (class II) to standard care in preventing irreversible lymphoedema after gynaeco-oncological therapy. METHODS AND ANALYSIS: In June 2022, two university hospitals in Belgium initiated a multicentre observational cohort study, which also includes an embedded RCT. The study aims to enrol 400 patients before they begin cancer treatment or within 14 days of starting chemotherapy, radiotherapy or surgery. This cohort will be followed for up to 2 years. The embedded RCT will focus on patients who develop clinical lymphoedema stage 0-1 within the first 12 months following their initial cancer treatment. A total of 196 patients will be randomised into two groups: the intervention group (98 patients), receiving usual care plus prophylactic compression garments (compression class 2 (CCL2): 23-32 mm Hg), and the control group (98 patients), receiving only usual care. The RCT aims to assess the impact of adding prophylactic compression garments to standard care on further deterioration. Assessments will be conducted at baseline, and at 3, 12 and 24 months after initial cancer treatment. An additional assessment (T-visit) will be provided if there is a transition to LLL stage 0-1 or from stage 0-1 to stage 2-3 LLL, based on follow-up findings or patient initiative, using the predictive value of a validated self-report lower extremity questionnaire. This questionnaire is part of a lymph diary app provided to all patients. The primary outcome of the observational study is to determine the incidence rate of stage 0-1 or stage 2-3 LLL in the first 2 years after gynaecological cancer treatment. The primary outcome of the RCT is to evaluate the effect of wearing CCL2 preventive garments to avoid progression to higher-stage lymphoedema in patients who develop LLL within 1 year of treatment. Key secondary outcomes of the observational study include the timing of the development of LLL, risk factors for developing LLL and the impact of LLL on QoL and sexuality, as well as the evaluation of screening and diagnostic tools. The secondary outcomes of the RCT include tolerance and compliance with wearing the preventive compressive garments, the impact of the garments on limb volume and the patient's time and financial investment. ETHICS AND DISSEMINATION: The study was approved by the Ethics Committee of the two academic hospitals: the University Hospital of Ghent in September 2021 and the University Hospital of Leuven in December 2021. Approval has been granted for the study protocol, informed consent forms and other related documents by the main Ethics Committee of Ghent (BC-09915) and the local Ethics Committee of Leuven (S65724). All patients will provide written informed consent before participating in the trial. The results will be shared through peer-reviewed journals and presentations. TRIAL REGISTRATION NUMBER: NCT05469945.

RESUMO

For over 2 decades, the mainstay of lymphedema treatment has been complete decongestive therapy, however, surgical options are available when conservative treatment is not successful in reducing lymphedema. Standardized pre-surgical and post-surgical guidelines for candidates are not readily available. As part of the 2023 Lymphedema Summit that was sponsored by the American Cancer Society, and the Lymphology Association of North America, an expert consensus workgroup was formed and developed an expert consensus which affirms the importance of pre-surgical guidelines for candidates with lymphedema. The workgroup recommended that guidelines should be tailored to four major end-user groups: (1) patients, (2) referring physicians, (3) allied health professionals, and (4) surgeons.

RESUMO

Several recent studies have investigated the validity of precautionary practices for lymphedema risk reduction after breast cancer treatment, such as avoidance of blood pressure measurements, skin puncture, blood draws, and use of prophylactic compression during air travel. Other studies have elucidated risk factors for breast cancer-related lymphedema, such as axillary lymph node dissection and skin infection (cellulitis). Combining the current evidence base with the consensus opinion of lymphatic experts assembled at the American Cancer Society/Lymphology Association of North America Summit in October 2023, updated evidence-based risk reduction recommendations are presented for those with or at risk of breast cancer-related lymphedema. Recommendation topics include prospective surveillance, patient education, individual risk factors, exercise, blood pressure, skin care and hygiene, skin puncture and blood draws, surgical procedures, prophylactic compression, air travel, and hot climate and sauna. These recommendations will help inform education and medical choices for individuals treated for breast cancer who are at risk of or diagnosed with breast cancer-related lymphedema. More high-quality evidence is required to allow the development of risk reduction recommendations for other cancer types such as gynecological, melanoma, and head and neck. It is recommended that clinicians and organizations serving people at risk of or with lymphedema align risk reduction guidelines with the evidence-based recommendations provided within this consensus document and companion manuscripts from the American Cancer Society/Lymphology Association of North America Lymphedema Summit: Forward Momentum: Future Steps in Lymphedema Management.

RESUMO

BACKGROUND: The lymphatic microsurgical preventive healing approach reduces the risk of lymphedema after axillary lymph node dissection. We identified surgical factors of Lymphatic Microsurgical Preventive Healing Approach (LYMPHA) that influence lymphedema rates focusing on the vein caliber used. METHODS: A single-institution retrospective cohort study included breast cancer patients undergoing axillary lymph node dissection and LYMPHA (April 2021-November 2022) with a follow-up of at least 1 year. Lymphedema was defined as an increase of ≥10 units in the lymphedema index (measured using bioimpedance spectroscopy) from baseline. The primary outcome was the correlation between the lymphedema index of patients with a vein caliber of ≤2 mm vs > 2 mm. RESULTS: Forty-eight patients with documented vein caliber were analyzed. The median baseline lymphedema index in patients with a vein caliber ≤2 mm was 2 (SD 3.04) and 2.2 (SD 2.03) for vein caliber >2 mm. (P = .57). After 1-year follow-up, the L-dex was 6.20 (SD 7.48) for vein caliber ≤2 mm and 1.60 (SD 5.85) for vein caliber >2 mm (P = .02). The L-dex difference from baseline was higher for vein caliber ≤2 mm compared to >2 mm (2.9 vs 0.10, P = .02). Larger vein caliber was associated with a lower L-dex at 3 months (P = .04) and a lesser difference from the baseline after 1 year (P = .03). This was maintained on univariate analysis and multivariate analysis controlling for radiation, chemotherapy, and number of lymph nodes excised. CONCLUSION: Vein caliber >2 mm during LYMPHA axillary lymph node dissection is associated with a lower postoperative lymphedema index. These results can be enhanced by a multi-institutional study to improve standardization of this technique.

RESUMO

Breast cancer related lymphedema (BCRL) affects many breast cancer survivors and drastically affects their quality of life. There are several surveillance methods for BCRL that are critical at early detection. Prevention of BCRL involves knowledge of alternatives to aggressive axillary surgery, avoidance of axillary surgery, and de-escalation of axillary surgery. There are also techniques to better delineate the anatomy in the axilla to avoid taking nodes that drain the upper extremity. A multidisciplinary approach with medical oncology and radiation oncology can also help avoid unnecessary surgery or radiation that can together strongly increase the risk of BCRL.

RESUMO

PURPOSE OF REVIEW: The most common surgical procedure associated with lymphedema formation is the regional lymphadenectomy. One of the advantages of sentinel node biopsy is the reduction of the risk of lymphedema formation. The purpose of this review is to collect and analyze the most relevant and recent evidence of the use of sentinel node biopsy and its implication on the development of postoperative lymphedema in gynecological cancer. RECENT FINDINGS: The current evidence of the use of sentinel node biopsy in cervical cancer to reduce lymphedema is heterogeneous and more data is needed to establish its role.Sentinel lymph node biopsy in endometrial cancer is a staging procedure with lower surgical complications, as well as lymphedema formation; while the results of prospective trials evaluating its impact on quality of life are still lacking.Sentinel lymph node biopsy in vulvar cancer minimizes the need for extensive dissection and reduces the incidence of complications associated with overharvesting of lymph nodes such as lymphedema without compromising oncological outcomes. SUMMARY: The prevalence of lymphedema in gynecological cancer varies based on the surgical treatment or additional therapies applied. Over the past years, one of the most important surgical modifications to decrease lymphedema formation has been implementation of sentinel lymph node technique mainly in vulvar cancer patients.

RESUMO

BACKGROUND: Although the association between higher physical activity and preventive effect on breast-cancer-related lymphoedema (BCRL) has been reported, it is unclear what intervention is optimal. We aimed to investigate the effect of exercise and educational programs on BCRL development. METHODS: This study was a secondary endpoint analysis from a prospective randomized controlled trial. We enrolled patients with stage 0-III breast cancer from March 2016 to March 2020 and randomly assigned them to the control (n = 111), education (n = 115), or exercise (n = 104) group. As secondary endpoint, we assessed the incidence of and preventive effect on BCRL at 12 months post-intervention. RESULTS: There were no significant differences in the incidence of BCRL at 12 months post-intervention between the exercise and control groups (9.8% and 10.8%, P = 0.83) and the education and control groups (11.6% and 10.8%, P = 1.00). There were no significant differences in time to BCRL onset from the day of surgery between the exercise and control groups (event rate at 12 months: 20.7% and 17.2%, log-rank, P = 0.54) and the education and control groups (18.8% and 17.2%, log-rank, P = 0.57). The multivariable analyses indicated that axillary dissection and obesity significantly increased the risk of BCRL [hazard ratio (HR): 2.36, 95% confidence interval (CI) 1.52-3.67 and HR: 1.68, 95% CI 1.07-2.63, respectively]. CONCLUSIONS: The intervention did not decrease the risk of BCRL, and axillary dissection and obesity were the risk factors of BCRL.

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

INTRODUCTION: Postoperative chronic lymphocele and lymphedema represent severe burdens for soft tissue sarcoma patients who are already physically handicapped after an extensive surgery and a long recovery time. Incidences are high in the upper medial thigh. We have shifted our focus to lymphedema and lymphocele risk reduction with immediate lymphovenous anastomosis (LVA) after sarcoma resection. METHODS: We performed immediate lymphatic reconstruction in 11 patients after soft tissue sarcoma resection in the upper medial thigh. The postoperative course was followed up closely, and postoperative occurrence of lymphocele and lymphedema was clinically assessed. A literature search outlining the latest clinical data, current treatment strategy landscape, and their application into clinical practice was added to the investigation. RESULTS: A total of 19 LVA and 2 lympho-lymphatic anastomoses were performed in 11 patients immediately after tumor resection in an end-to-end manner. We found a postoperative lymphedema rate of 36% and a postoperative lymphocele rate of 27%. Mean follow-up time was 17 months. Average tumor volume was 749 cc. Our literature search yielded 27 articles reporting on immediate LVA in cancer patients. Incidences of secondary lymphedema after LVA for lymphedema prevention vary between 0% and 31.1%. Lymphocele prevention with LVA is poorly studied in sarcoma patients. CONCLUSION: Immediate lymphatic reconstruction improved the overall postoperative course of our patients. The current literature does not serve with high-quality studies about primary LVA preventing lymphedema and lymphocele formation. We conclude that this technique should be seen as an additional concept to achieve overall better postoperative outcomes in these challenging surgical settings. We strongly recommend to either anastomose or ligate severed lymphatics under the microscope primarily after sarcoma resection in the upper medial thigh area.

RESUMO

Advances in the diagnosis and treatment of breast cancer have significantly improved survival rates. Breast cancer-related lymphedema is the most common mid-and long-term complication after breast cancer surgery, which seriously affects the quality of life. Breast reconstruction can not only restore the shape of the breasts after mastectomy, but also reduce the occurrence of lymphedema to some extent. Immediate autologous breast reconstruction combined with lymphatic venous anastomosis (LVA) or vascularized lymph node transfer (VLNT) can effectively prevent lymphedema. Delayed breast reconstruction combined with LVA or VLNT can achieve the dual benefits of restoring the appearance and treating lymphedema at the same time. The autologous tissue flap can function as a bridge to promote lymphatic drainage, thus enhancing the treatment of lymphedema. The advances mentioned above in surgical techniques have provided a basis for decision making in breast reconstruction and the prevention and treatment of breast cancer-related lymphedema, and have also brought hope for improving the quality of life of patients.

RESUMO

BACKGROUND: Breast cancer-related lymphedema (BCRL) poses a significant risk following sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND), particularly affecting ethnic minorities, with a twofold increased risk. Axillary reverse mapping (ARM), a novel technique, shows potential in reducing BCRL rates, yet its utility in ethnic minorities lacks sufficient exploration. Therefore, our study aims to investigate the utility and outcomes of ARM on BCRL in an ethnic diverse group. METHODS: A retrospective chart review of ARM patients from January 2019 to July 2022 was conducted, monitoring patients over 24 months at 3-month intervals using SOZO® scores, with comparisons with preoperative baselines. RESULTS: Of the 212 patients, 83% belonged to ethnic minorities. SLNB was performed in 83%, ALND in 17%, and 62.3% underwent radiation therapy. Positive lymph nodes were found in 31.6%, with 22.2% exhibiting blue nodes and 25.9% exhibiting blue lymphatics. Of identified blue nodes, 70.2% were excised, including 51.5% crossover nodes. Lymphedema occurred in 3 patients, resulting in a BCRL rate of 1.4%. Compared with an historical BCRL incidence of 40.4% following ALND in ethnic minorities, our study reported a significantly lower rate of 8% (p < 0.001). CONCLUSION: The ARM procedure can significantly lower BCRL in ethnic minority groups. The combination of ARM and bioimpedance spectroscopy led to a remarkably low BCRL rate of 1.4%. Notably, none of the patients in our study developed an axillary recurrence at 24-month follow-up. Nevertheless, future studies with larger sample sizes are warranted to better understand the utility of the ARM technique in this population.

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

With new investigations and clinical trials in breast oncology reported every year, it is critical that surgeons be aware of advances and insights into the evolving care paradigms and treatments available to their patients. This article highlights five publications found to be particularly impactful this past year. These articles report on efforts to select the minimal effective dose of tamoxifen for prevention, to challenge the existing age-based screening guidelines as they relate to race and ethnicity, to refine axillary management treatment standards, to optimize systemic therapy in multidisciplinary care settings, and to reduce the burden of breast cancer-related lymphedema after treatment. Taken together, these efforts have an impact on all facets of the continuum of care from prevention and screening through treatment and survivorship.

RESUMO

BACKGROUND: Studies have shown a significant reduction in breast cancer-related lymphedema (BCRL) rates in patients undergoing complete axillary lymph node dissection (cALND) combined with immediate lymphatic reconstruction (ILR) using lymphovenous bypass (LVB).The purpose of this study was to determine if ILR with LVB at the time of cALND results in a decreased incidence of BCRL and its impact on patient quality of life (QOL). METHODS: In this prospective cohort study, patients ≥ 18 years requiring cALND underwent ILR from 2019 to 2021. The primary outcome was bilateral upper limb volumes measured by Brørson's truncated cone formula and the Pero-System (3D Körper Scanner). The secondary outcome was QOL measured by the Lymphedema Quality of Life (LYMQOL) arm patient-reported outcome measurement. RESULTS: Forty-two patients consented to ILR using LVB. ILR was completed in 41 patients with a mean of 1.9 ± 0.9 lymphovenous anastomosis performed. Mean age of patients was 52.4 ± 10.5 years with a mean body mass index of 27.5 ± 4.9 kg/m2. All patients (n = 39, 100%) received adjuvant therapy after ILR. Mean follow-up was 15.2 ± 5.1 months. Five patients met criteria for lymphedema throughout the duration of the study (12.8%), with two patients having resolution, with an overall incidence of 7.7% by the end of the study period. Patients with lymphedema were found to have statistically significant lower total LYMQOL values at 18 months (8.44 ± 1.17 vs. 3.23 ± 0.56, p < 0.001). A mean increase of 0.73 ± 3.5 points was observed for overall QOL average for upper limb function at 18 months compared with 3 months (t = 0.823, p = 0.425). CONCLUSION: This study showed an incidence of 7.7% lymphedema development throughout the duration of study. We also showed that ILR has the potential to reduce the significant long-term adverse outcomes of lymphedema and improve QOL for patients undergoing cALND.

RESUMO

Lymphedema in the upper and lower extremities can lead to significant morbidity in patients, resulting in restricted joint movements, pain, discomfort, and reduced quality of life. While physiological lymphatic reconstructions such as lymphovenous anastomosis (LVA), lymphovenous implantation (LVI), and vascularized lymph node transfer (VLNT) have shown promise in improving patients' conditions, they only provide limited disease progression control or modest reversal. As lymphedema remains an incurable condition, the focus has shifted toward preventive measures in developed countries where most cases are iatrogenic due to cancer treatments. Breast cancer-related lymphedema (BCRL) has been a particular concern, prompting the implementation of preventive measures like axillary reverse mapping. Similarly, techniques with lymph node-preserving concepts have been used to treat lower extremity lymphedema caused by gynecological cancers. Preventive lymphedema measures can be classified into primary, secondary, and tertiary prevention. In this comprehensive review, we will explore the principles and methodologies encompassing lymphatic microsurgical preventive healing approach (LYMPHA), LVA, lymphaticolymphatic anastomosis (LLA), VLNT, and lymph-interpositional-flap transfer (LIFT). By evaluating the advantages and limitations of these techniques, we aim to equip surgeons with the necessary knowledge to effectively address patients at high risk of developing lymphedema.

RESUMO

Breast cancer-related lymphedema is a lifelong disease associated with decreased quality of life and increased healthcare costs. Evidence supports early detection and prompt treatment through prospective surveillance models.

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

This case study describes the successful management of a patient with primary lymphoedema, who was experiencing lymphorrhoea and epidermolysis, using a multidisciplinary approach. The patient had Klippel-Trenaunay syndrome. The multidisciplinary team, in an outpatient clinic in Japan, included a certified lymphoedema therapist, plastic surgeons, and a wound, ostomy and continence nurse. The team performed complex physical therapy and lymphaticovenular anastomosis, which promoted the resolution of the lymphorrhoea. This resulted in improvements in skin condition, the prevention of recurrent cellulitis, and no increase in limb circumferences during the 1-year follow-up period. This report highlights the importance of a multidisciplinary approach to lymphoedema management, including lymphorrhoea control that fitted in with the patient's daily life. It is hoped that this article will contribute to the improvement of the quality of life of patients with lymphoedema.
