Psychological Stress and Its Correlations to Patients with Acute Lymphedema After Breast Cancer Surgery

Background

Lymphedema and psychological distress, including anxiety and depression, are common in breast cancer patients post-surgery. This study aimed to assess the incidence and determinants of anxiety and depression in patients with acute lymphedema (ALE) following breast cancer surgery.

Methods

A retrospective study was conducted on 1613 breast cancer patients who underwent surgery at Fudan University Shanghai Cancer Center in 2018. ALE was defined as lymphatic fluid accumulation causing limb swelling and was classified by the difference in arm circumference. Anxiety and depression were evaluated using the Hospital Anxiety and Depression Scale (HADS) at discharge. Descriptive statistics and logistic regression were used to identify psychological distress-related factors.

Results

Among the 1613 patients, 363 (22.5%) had ALE. Anxiety was observed in 31% and depression in 21% of patients. ALE significantly impacted anxiety in the multivariate analysis (OR = 1.57, 95% CI: [1.04-2.38], P = 0.033). Multivariate analysis of ALE patients showed that longer hospital stays (OR = 0.51, 95% CI: [0.30-0.88], P = 0.017) and invasive disease (OR = 0.39, 95% CI: [0.19-0.78], P = 0.008) were associated with reduced anxiety; while lymph-vessel invasive disease was associated with increased anxiety (OR = 5.97, 95% CI: [1.15-30.97], P = 0.034). ALE had no significant impact on depression in the multivariate analysis. However, menopause (OR = 0.72, 95% CI: [0.56-0.94], P = 0.014) and longer hospitalization (OR = 1.30, 95% CI: [1.00-1.68], P = 0.047) influenced depression in all patients. In the ALE group, lymph node surgery was the only significant factor for depression (OR = 8.67, 95% CI: [1.56-48.23], P = 0.014) in the multivariate analysis.

Conclusion

Psychological stress, influenced by both surgical factors and emotional states, is associated with ALE development. Addressing both psychological and surgical factors is crucial for improving outcomes and quality of life in post-surgery breast cancer patients.

Effect of Complex Decongestive Therapy Program on Volume and Functioning in Breast Cancer-Related Lymphedema: Global Effect and Predicting Factors

Background: The aim of this prospective study was to investigate the effect of a first and repeated complex decongestive therapy (CDT) program on volume and functioning in patients with unilateral breast cancer-related lymphedema (BCRL) and to identify whether the volume before treatment and/or the number of previous treatment influence outcomes. Methods and Results: In total, 100 and 42 patients with BCRL treated by 499 CDT (6 hours a day during 5 consecutive days) between April 2018 and December 2021 were included. Patients were assessed using volume including percentage of excess volume and percentage reduction in excess volume and lymph-International Classification of Functioning-UL questionnaire. After CDT, a significant reduction in BCRL volume (50%) and improvement in functioning (30%) were observed. The volume reduction was greater when the BCRL volume before treatment was low (10%-20%) and when CDT was performed for the first time. The functioning improvement was identical whatever the volume is before treatment and the number of previous CDT. Conclusion: A greater volume reduction after CDT was obtained in BCRL with low volume before treatment and after the first CDT. Such findings support the need for early intensive BCRL treatment to control volume and improve functioning.

Effectiveness of complete decongestive therapy for upper extremity breast cancer-related lymphedema: a review of systematic reviews

Breast cancer-related lymphedema (BCRL) remains a challenging condition impacting function and quality of life. Complete decongestive therapy (CDT) is the current standard of care, necessitating a comprehensive review of its impact. This paper presents a systematic review (SR) of SRs on CDT's efficacy in BCRL, and the components of manual lymph drainage (MLD) and exercise. A literature search yielded 13 SRs published between January 2018 and March 2023 meeting inclusion criteria, with varied quality ratings based on the AMSTAR II. A sub-analysis of CDT investigated the within group effect size estimations on volume in different stages of lymphedema. While a moderate quality SR indicated support for CDT in volume reduction, other SRs on the topic were of critically low quality. Larger effect sizes for CDT were found for later stage BCRL. The impact of MLD as a component of CDT demonstrated no additional volume benefit in a mix of moderate to low quality SRs. Similarly, exercise's role in volume reduction in CDT was limited, although it demonstrated some benefit in pain and quality of life. A rapid review of trials published January 2021-March 2023 reinforced these findings. Variability in CDT delivery and outcomes remained. These findings underscore the need to standardize staging criteria and outcome measures in research and practice. Future research should focus on refining interventions, determining clinically important differences in outcomes, and standardizing measures to improve evidence-based BCRL management. Current evidence supports CDT's efficacy in BCRL. MLD and exercise as components of CDT have limited support for volume reduction.

Essential components of the maintenance phase of complex decongestive therapy

Complex decongestive therapy is the current gold standard for non-surgical clinical lymphedema management and consists of manual therapy, compression exercise, skincare, and education. Complex decongestive therapy involves an intensive volume reduction phase (Phase I) followed by a maintenance phase (Phase II). The aim of the maintenance phase is to promote life-long control of lymphedema through use of self-management strategies and the provision of ongoing reduction therapies as needed. Compression therapies are the mainstay of lymphedema self-management. Poor adherence to self-management practices has been associated with increased volume and progression of lymphedema to more advanced stages, supporting the importance of education and regular monitoring to promote adherence to the Phase II maintenance recommendations. In this editorial, we provide consensus recommendations on the essential components of the maintenance phase, including education, skin care practices, managing infection/cellulitis, compression therapies, health and weight management, exercise, and ongoing follow-up care.

Reliability, concurrent validity, and clinical feasibility of measurement methods determining volume in patients with lower limb lymphedema and healthy controls

PURPOSE

To investigate reliability, concurrent validity, and clinical feasibility of measurements assessing volume in patients with lower limb lymphedema (LLL) and healthy controls.

MATERIALS AND METHODS

To investigate intra- and interrater reliability, 47 patients with LLL and 30 healthy controls were assessed three times by two assessors. To investigate between session reliability, 50 participants were reassessed two weeks later. Each assessment included measurements of the midline region (hip circumference; suprapubic volume), leg volume (perimeter every 4 cm; Perometer®), and foot volume (water displacement; figure-of-eight method). Concurrent validity was assessed with correlation coefficients. Measurements were timed and practical limitations were reviewed. Clinical trial registration number: NCT: 05269264.

RESULTS

Measurements of the total volume of different regions showed weak to very high intraclass correlation coefficients (ICCs) (0.131-998). Absolute and relative volume differences had lower ICC values (0.360-0.976). A strong correlation was found between the total volumes of the same region. The Perometer® and figure-of-eight method were the fastest method for leg and foot volume, respectively.

CONCLUSIONS

The assessed total volumes might be more valuable in assessing the evolution of volume in bilateral LLL than the calculated absolute and relative differences between both limbs. The Perometer® and figure-of-eight method were the most time efficient for leg and foot volume, respectively.Implications for rehabilitationLymphedema is a chronic condition for which a reliable and clinically feasible assessment of volume is essential for the diagnosis, treatment decisions, and the evaluation of the treatment.This study shows that the total leg/foot volumes were more reliable than the calculated absolute and relative differences between both limbs and could therefore more valuable to evaluate bilateral lower limb lymphedema.For the assessment of leg volume, the Perometer® was the most reliable and fastest method.For the evaluation of the foot volume, the figure-of-eight method was overall the best method.

Development of a core set of outcome measures to be applied toward breast cancer-related lymphedema core outcome domains

PURPOSE

For breast cancer survivors (BCS) living with breast cancer-related lymphedema (BCRL), what outcome measures (OMs) are recommended to be used to measure standardized outcome domains to fully assess the burden of the disease and efficacy of interventions? An integral component of a standardized core outcome set (COS) are the OMs used to measure the COS.

METHODS

A supplemental online survey was linked to a Delphi study investigating a COS for BCRL. OMs were limited to a maximum of 10 options for each outcome domain (OD). There were 14 ODs corresponding to the International Classification of Functioning, Disability, and Health (ICF) framework and respondents rated the OMs with a Likert level of recommendation. The feasibility of the listed OMs was also investigated for most outpatient, inpatient, and research settings.

RESULTS

This study identified 27 standardized OMs with a few ODs having 2-3 highly recommended OMs for proper measurement. A few of the recommended OMs have limitations with reliability due to being semi-quantitative measures requiring the interpretation of the rater.

CONCLUSION

Narrowing the choices of OMs to 27 highly recommended by BCRL experts may reduce selective reporting, inconsistency in clinical use, and variability of reporting across interdisciplinary healthcare fields which manage or research BCRL. There is a need for valid, reliable, and feasible OMs that measure tissue consistency. Measures of upper extremity activity and motor control need further research in the BCS with BCRL population.

SurLym trial: study protocol for a multicentre pragmatic randomised controlled trial on the added value of reconstructive lymphatic surgery to decongestive lymphatic therapy for the treatment of lymphoedema

INTRODUCTION

Lymphoedema is a chronic condition caused by lymphatic insufficiency. It leads to swelling of the limb/midline region and an increased risk of infection. Lymphoedema is often associated with mental and physical problems limiting quality of life. The first choice of treatment is a conservative treatment, consisting of exercises, skin care, lymph drainage and compression. Reconstructive lymphatic surgery is also often performed, that is, lymphovenous anastomoses, lymph node transfer or a combination. However, robust evidence on the effectiveness of reconstructive lymphatic surgery is missing. Therefore, the objective of this trial is to investigate the added value of reconstructive lymphatic surgery to the conservative treatment in patients with lymphoedema.

METHODS AND ANALYSIS

A multicentre randomised controlled and pragmatic trial was started in March 2022 in three Belgian university hospitals. 90 patients with arm lymphoedema and 90 patients with leg lymphoedema will be included. All patients are randomised between conservative treatment alone (control group) or conservative treatment with reconstructive lymphatic surgery (intervention group). Assessments are performed at baseline and at 1, 3, 6, 12, 18, 24 and 36 months. The primary outcome is lymphoedema-specific quality of life at 18 months. Key secondary outcomes are limb volume and duration of wearing the compression garment at 18 months. The approach of reconstructive lymphatic surgery is based on presurgical investigations including clinical examination, lymphofluoroscopy, lymphoscintigraphy, lymph MRI or CT angiography (if needed). All patients receive conservative treatment during 36 months, which is applied by the patient's own physical therapist and by the patient self. From months 7 to 12, the hours a day of wearing the compression garment are gradually decreased.

ETHICS AND DISSEMINATION

The study has been approved by the ethical committees of University Hospitals Leuven, Ghent University Hospital and CHU UCL Namur. Results will be disseminated via peer-reviewed journals and presentations.

Knowledge, attitude and practice of physiotherapists about lymphedema: A Turkish perspective

BACKGROUND

Physiotherapists are important members of the healthcare team in the management of lymphedema. Therefore, the level of knowledge and awareness of physiotherapists on this disease is substantial. This study was planned to investigate knowledge, attitude, and practice of physiotherapists about lymphedema in Turkey.

METHOD

This study was a qualitative, prospective, and cross-sectional research. Data were collected with the web-survey which consisted of the demographical characteristics information, evaluation of their own knowledge and practice in lymphedema management, and current knowledge of physiotherapists about lymphedema based on the current literature.

RESULTS

Two hundred seventy-four physiotherapists (174 Female: 100 Male; mean age: 29.87 ± 6.9 years) completed the web-survey. From 274 physiotherapists, 52.60% of them had no education about lymphedema, 13.90% of them had never seen any patient with lymphedema, and 57.70% of them had not taken part in the management of a patient with lymphedema. 71.90% of the physiotherapists did not think they have enough knowledge about lymphedema. It was identified that physiotherapists' general and risk factors knowledge about lymphedema was sufficient. However, physiotherapists showed a lack of knowledge on the evaluation, treatment, and recommendations for lymphedema.

CONCLUSION

Physiotherapists' education and experience in lymphedema management are crucial as they are important members of the multidisciplinary team. To raise qualified physiotherapists in this field, from undergraduate education, special training programs about lymphedema should be added to their lifelong learning process.

Breast cancer survivors' experiences of barriers and facilitators to lymphedema self-management behaviors: a theory-based qualitative study

PURPOSE

Lifelong self-management plays a critical role in the prevention and management of lymphedema among breast cancer survivors. However, adherence to lymphedema self-management behaviors has remained suboptimal. Hence, we adopted a theory-informed method to elucidate the facilitators and barriers of lymphedema self-management for breast cancer survivors.

METHODS

In-depth semi-structured interviews were conducted between August and October 2022 in the lymphedema nursing clinic of a tertiary cancer hospital. The maximum variation sampling technique was used to ensure a diverse sample. The ITHBC (Integrated Theory of Health Behavior Change) framework was used to inform the interview outline and data analysis. Interview transcripts were coded line-by-line and mapped to domains in accordance with the ITHBC, using both deductive and inductive content analysis.

RESULTS

A total of 16 participants were interviewed (aged 35 to 67). Twenty-three themes (12 facilitators and 11 barriers) were mapped onto the three domains (knowledge and belief, social facilitation, and self-regulation skill and ability) of ITHBC as facilitators and barriers to lymphedema self-management. Three additional themes including limited treatment resources for lymphedema, inconvenience of lymphedema management, boredom and tedium of lymphedema self-management were categorized under the domain of other barriers.

CONCLUSIONS

Incorporating these findings into the ITHBC framework allows for a more systematic selection of theory-based strategies that may improve the design of effective lymphedema self-management interventions for breast cancer survivors.

IMPLICATIONS FOR CANCER SURVIVORS

Elucidating impact factors, especially facilitators and barriers, for lymphedema self-management adherence is essential for developing effective intervention programs to enhance breast cancer survivors' lymphedema self-management behaviors.

The Appraisal of Clinical Practice Guidelines for Breast Cancer-Related Lymphedema

Background: Approaches to screening, assessment, and treatment of breast cancer-related lymphedema (BCRL) vary widely. We evaluated overall quality of clinical practice guidelines (CPGs) for managing BCRL using the Appraisal of Guidelines for REsearch and Evaluation II (AGREE II) tool, and relevance of consensus recommendations for the Canadian health context. Methods and Results: We searched electronic databases, gray literature, national lymphedema frameworks, and expert opinions, to identify lymphedema CPGs, printed/published from January 2013 to October 2021. Using AGREE II, six health care professionals reviewed CPGs for consensus. Domain-specific AGREE II quality consensus scores were required (≥70% for Rigor of Development; ≥ 60% for Stakeholder Involvement and Editorial Independence; and ≥50% for Clarity of Presentation, Applicability, Scope, and Purpose). Results and overall recommendations from the CPGs were summarized and synthesized. Nine CPGs met inclusion criteria for review. Wide variability of evidence-based recommendations, and limited clinical considerations were found. Scope and Purpose, and Clarity of Presentation were adequate in six of nine CPGs; Stakeholder Involvement in seven of nine CPGs; and Editorial Independence in three of nine CPGs. Across all CPGs, Applicability was minimally reported. Only the Queensland Health CPG met quality consensus scores for Rigor and Development; however, the focus was limited to compression therapy. Conclusions: No CPG reviewed could be adopted for the Canadian health context. The proposed Canadian BCRL CPG will focus on stakeholder engagement, methodology, and implementation/evaluation. Using AGREE II allowed for assessment of quality of methods used to develop identified CPGs from other countries before consideration of adoption in a Canadian Context.

Pediatric and Family Physicians' Attitudes Regarding Childhood Optional Vaccines During the COVID-19 Pandemic

INTRODUCTION

To maintain high vaccination rates, vaccination interventions should be targeted according to interests such as parents' knowledge, attitudes, beliefs, and vaccine hesitancy.

METHODS

This research was conducted between June 2020 and April 2021 using a questionnaire about optional vaccines (OVs) in Turkey.

RESULTS

A total of 241 physicians participated and 14 physicians were excluded due to insufficient data. Finally, a total of 227 physicians, including 115 pediatricians and 112 family physicians, were included in the study. The mean age of pediatricians and family physicians was 33.42 ± 8.25 years and 35.46 ± 11.09 years, respectively. There was no significant difference between pediatricians and family physicians in terms of age and gender (p > 0.05). Nearly half of all physicians (49%) stated that they do not have sufficient knowledge about OVs. Pediatricians (64%) stated that they have sufficient knowledge at a higher rate than family physicians (37%) (p = 0.000). Physicians who declared having sufficient knowledge informed families about OVs more frequently than those with insufficient knowledge (p = 0.000). Pediatricians provide information about OVs more frequently than family physicians (p = 0.001). Rotavirus and meningococcal vaccines were the most frequently recommended vaccines.

CONCLUSIONS

Rotavirus and meningococcal B were the most recommended OVs. About half of the physicians participating in the study stated that they did not have sufficient knowledge about OVs. Physicians with sufficient knowledge of OVs recommend OVs more frequently.

Comparison of Actual and Predicted Resting Metabolic Rate in Women with Lipedema

Background: An adequate dietary energy supply is particularly important in patients with lipedema as it promotes weight and fat loss. Accurate estimation of resting metabolic rate (RMR) allows implementing a proper calorie restriction diet in patients with lipedema. Our study aimed to compare actual resting metabolic rate (aRMR) with predicted resting metabolic rate (pRMR) in women with lipedema and to determine the association between individual body composition parameters, body mass index, and aRMR. Methods and Results: A total of 108 women diagnosed with lipedema were enrolled in the study. aRMR was obtained by indirect calorimetry (IC) using FitMate WM metabolic system (Cosmed, Rome, Italy). pRMR was estimated with predictive equations and bioelectric impedance analysis (BIA). All body composition parameters were based on BIA. The mean aRMR in the study group was 1705.2 ± 320.7 kcal/day. This study found the agreement of predictive equations compared to IC is low (<60%). Most methods of predicted RMR measurement used in our study significantly underpredicted aRMR in patients with lipedema. Therefore, the most applied equations remain useless in clinical practice in this specific population due to large individual differences among the studied women. Conclusions: IC is the best tool to evaluate RMR in evaluated patients with lipedema. It is necessary to propose a new equation to RMR determination in clinical practice.

Guidelines Relevant to Diagnosis, Assessment, and Management of Lymphedema: A Systematic Review

Significance: Lymphedema is a common, distressing and debilitating condition with various etiologies. Effective diagnosis, assessment, and management rely on evidence-based clinical practice guidelines ("guidelines"). This study aims to describe and compare international guidelines on lymphedema diagnosis, assessment, and management. Recent Advances: The review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and registered on the International Prospective Register of Systematic Reviews (PROSPERO). Systematic searches of electronic literature databases and the web were completed in December 2020 for lymphedema guidelines published in English since 2000. Quality was assessed using the Appraisal of Guidelines for Research and Evaluation (AGREE)-II reporting checklist. Synthesis took a narrative approach to compare guideline recommendations and associated levels of evidence. Critical Issues: This systematic review of 1,564 articles and 159 web pages yielded 14 guidelines. All guidelines were from high-income countries. Ten focused exclusively on lymphedema, and four on cancer. Most (n = 13) guidelines recommended an integrated medical, psychological assessment, and physical examination, with a limb volume measurement of >10% in the affected limb compared, confirming a lymphedema diagnosis. Recommended management involved Complex Decongestive Therapy (CDT) followed by self-management using skincare, self-lymphatic drainage massage, exercise, and compression. Future Directions: The underlying etiology of lymphedema appeared to make little difference to guideline recommendations regarding care. High-quality guidelines are available to guide lymphedema care. However, their suitability for low-resource settings is unclear.

Self-managed physical activity in breast cancer survivors: A scoping review

OBJECTIVE

Breast cancer survivors (BCS) experience many issues of rehabilitative concern due to the treatments they have undergone. Given the chronicity of these outcomes, the increasing number of survivors, and the positive results obtained by supervised exercise, professionals should consider offering self-managed physical activity (PA) programs to this population. Our aim was to map the currently available evidence about self-care rehabilitation for BCS.

METHODS

Medline, CINAHL, and Cochrane databases were searched for primary literature. Scoping review methodological frameworks were used to tackle the heterogeneity of the topic. Studies investigating self-managed PA interventions prescribed to adult BCS were included.

RESULTS

One hundred-eight studies were included, with sample sizes ranging from 6 to 692 patients. Information was systematically collected in tables displaying study design, type of PA, duration and recommended frequency, professional leading the study, type of supervision, initial training, strategies used to help patients integrate self-care into their daily lives, and self-managed PA efficacy. Tables were produced for every oncological side effect that BCS might experience: lymphedema, arthralgia, cancer-related fatigue, a decline in physical parameters, treatment-related cardiotoxicity, peripheral neurotoxicity, and a possible decline in the quality of life.

CONCLUSIONS

Self-managed PA has the potential to improve BCS oncological issues. Professionals can adopt many strategies to support patients and empower them with long-lasting self-care competencies. This scoping review provided a comprehensive and easy-to-consult overview of self-managed PA interventions for BCS. We also provided recommendations for future primary studies and secondary synthesis.

Does Manual Lymphatic Drainage Add Value in Reducing Suprafascial Fluid Accumulation and Skin Elasticity in Patients With Breast Cancer-Related Lymphedema?

OBJECTIVE

The purpose of this study was to investigate the effectiveness of fluoroscopy-guided manual lymph drainage (MLD) versus that of traditional and placebo MLD, when added to decongestive lymphatic therapy (DLT) for the treatment of breast cancer-related lymphedema (BCRL) (EFforT-BCRL trial), on the suprafascial accumulation of lymphatic fluid and skin elasticity.

METHODS

In this multicenter, 3-arm, double-blind, randomized controlled trial (EFforT-BCRL trial), 194 participants (mean age = 61 [SD = 10] years) with unilateral BCRL were recruited. All participants received standardized DLT (education, skin care, compression therapy, exercises) and were randomized to fluoroscopy-guided, traditional, or placebo MLD. Participants received 60 min/d of treatment during the 3-week intensive phase and 18 sessions of 30 minutes during the 6-month maintenance phase. During this phase, participants were instructed to wear a compression garment, to perform exercises, and to perform a self-MLD procedure once daily. This study comprises secondary analyses of the EFforT-BCRL trial. Outcomes were the amount of fluid accumulation in the suprafascial tissues (local tissue water, extracellular fluid, and thickness of the skin and subcutaneous tissue) and skin elasticity at the level of the arm and trunk. Measurements were performed at baseline; after intensive treatment; after 1, 3, and 6 months of maintenance treatment; and after 6 months of follow-up.

RESULTS

At the level of the arm, there was a significant improvement over time in the 3 groups for most of the outcomes. At the level of the trunk, no remarkable improvement was noted within the individual groups. No significant interaction effects (between-group differences) were present. Only skin elasticity at the level of the arm, evaluated through palpation, showed a significant interaction effect.

CONCLUSION

All 3 groups showed similar improvements in response to DLT regardless of the type of MLD that was added. The effect of the addition of MLD to other components of DLT for reducing local tissue water and extracellular fluid or skin thickness and for improving skin elasticity and fibrosis in participants with chronic BCRL was limited.

IMPACT

Although MLD has been applied all over the world for many years, evidence regarding its added value in reducing arm volume in patients with BCRL is lacking. These results show that adding MLD to other components of DLT has limited value in reducing local tissue water and extracellular fluid or skin thickness and in improving skin elasticity and fibrosis in patients with chronic BCRL. To date, there is no clinical indication to continue including time-consuming MLD in physical therapist sessions for patients with chronic BCRL.

Early Referral for Breast-Cancer-Related Lymphedema: Do We Follow the Evidence? A Two-Year Prospective Multicenter Cohort Study

The early detection of breast-cancer-related lymphedema and referral for therapy has the potential to reduce lymphedema-related morbidity. Although research shows the benefits, a gap is observed between evidence and daily practice. We aimed to determine whether the early detection of lymphedema and referral for treatment is adequate following the current guidelines. Women with primary breast cancer treated with breast-conserving therapy or ablative treatment were included. Demographic-, general health-, tumor-, and treatment-related data were recorded. Bilateral arm volume measurements were performed preoperatively and 3, 6, 12, and 24 months post-surgery. A 5% or greater Relative Volume Change was considered the cutoff point for lymphedema and as an indication for therapy referral. After 24 months post-surgery, the main outcomes show that among the patients with early signs of lymphedema, based on a Relative Volume Change ≥5%, a nonreferral for therapy was noted in 83%. Additionally, we observed a significant improvement of the mean Relative Volume Change at 24 months within this group, which might implicate that nonreferral was an adequate choice and that watchful waiting is appropriate when lymphedema is detected within the first year post-surgery.

Sun-burn induced upper limb lymphedema 11 years following breast cancer surgery: A case report

BACKGROUND

Upper arm lymphedema is a common complication one year after breast cancer surgery, which profoundly impacts patients' quality of life.

CASE SUMMARY

We reported a case of lymphedema induced by prolonged sun exposure 11 years after breast cancer surgery.

CONCLUSION

Breast screening, patient education and follow-up after hospital discharge could help to prevent upper-arm lymphedema.

Lymphatic anomalies during lifetime in patients with Noonan syndrome: Retrospective cohort study

Noonan syndrome (NS) has been associated with an increased risk of lymphatic anomalies, with an estimated prevalence of 20%. The prevalence of lymphatic anomalies seems to differ between pathogenic variants. Therefore, this study aims to describe the clinical presentation, prevalence and genotype-phenotype correlations of lymphatic anomalies during life in patients with NS. This retrospective cohort study included patients (n = 115) who were clinically and genetically diagnosed with NS and visited the Noonan expertise Center of the Radboud University Medical Center between January 2015 and March 2021. Data on lymphatic anomalies during lifetime were obtained from medical records. Lymphatic anomalies most often presented as an increased nuchal translucency, chylothorax and/or lymphedema. Prenatal lymphatic anomalies increased the risk of lymphatic anomalies during infancy (OR 4.9, 95% CI 1.7-14.6). The lifetime prevalence of lymphatic anomalies was 37%. Genotype-phenotype correlations showed an especially high prevalence of lymphatic anomalies during infancy and childhood in patients with a pathogenic SOS2 variant (p = 0.03 and p < 0.01, respectively). This study shows that patients with NS have a high predisposition for developing lymphatic anomalies during life. Especially patients with prenatal lymphatic anomalies have an increased risk of lymphatic anomalies during infancy. Genotype-phenotype correlations were found in pathogenic variants in SOS2.

Development and psychometric evaluation of a lymphoedema self-management behaviour questionnaire for breast cancer patients

OBJECTIVES

The study was aimed to develop and evaluate a lymphoedema self-management behaviour questionnaire (LSMBQ) for breast cancer patients.

METHODS

The initial version of the behaviour questionnaire was developed based on the framework of self-management and the evidence summary of lymphoedema self-management. Two rounds of expert consultation were conducted to validate the questionnaire's content validity. A cross-sectional survey was then conducted in breast wards of two hospitals in China to evaluate the reliability and validity of this scale. Exploratory structural equation model was used to test the construct validity. T-test was used to analyse the known group validity. Structural equation model was applied to verify the relationship between self-efficacy, social support, and lymphoedema self-management behaviour to test the convergent validity. Also, the internal consistency reliability and test-retest reliability were evaluated.

RESULTS

The questionnaire's content validity was satisfactory. There were 22 items included in the LSMBQ for validation and 260 completed the survey. A six-factor structure with good construct validity was identified. The result of t-test verified that patients who knew the risk of lymphoedema and those who received lymphoedema health education had higher scores of lymphoedema self-management behaviours (P < 0.05), indicating that the questionnaire has good known group validity. The fitting results of the structural equation model indicated that the 22-item questionnaire had good convergent validity. Cronbach's alpha coefficients and test-retest reliability for the total questionnaire were 0.910 and 0.875, respectively.

CONCLUSIONS

The 22-item LSMBQ appears to have adequate reliability and validity to assess the lymphoedema self-management behaviours for breast cancer patients.

Breast cancer-related lymphoedema and resistance exercise: An evidence-based review of guidelines, consensus statements and systematic reviews

AIMS AND OBJECTIVES

Breast cancer-related lymphoedema (BCRL) is a side effect of cancer treatment and can be alleviated by resistance exercise. This systematic, evidence-based review examined the existing best evidence on resistance exercise for BCRL to accurately describe the current status of the field and offer recommendations for clinicians.

METHODS

This review adheres to the PRISMA guidelines. Clinical practice guidelines, consensus documents, systematic reviews and other related evidence-based resources about resistance exercise for BCRL were retrieved through the English databases and guideline websites. The publication data limit was set to December 2020. The following search terms were used: 'breast cancer/breast neoplasm/breast carcinoma/breast tumor/breast malignancy, lymphedema/swelling/edema/lymphoedema, resistance/weight/strength training, best practice/clinical practice/guideline/consensus documents'. The quality of the included studies was evaluated by two authors independently using AGREE II and AMSTAR II tools. Evidence-based recommendations on resistance exercise relevant for BCRL were synthesised and categorised.

RESULTS

Twenty two articles (seven guidelines, four consensus documents and eleven systematic reviews) were included. The overall quality of the eleven eligible guidelines and consensus documents was moderate to high according to the AGREE II criteria. The quality of the eleven systematic reviews was critically low to high according to the AMSTAR criteria. Six clinical topics involving 43 recommendations were identified. Recommendations were categorised by safety of resistance training, effectiveness of resistance training, evaluation prior to resistance exercise, resistance exercise prescription, resistance training outcome index and points for attention.

CONCLUSIONS

This study summarises 43 recommendations for resistance training for BCRL and provides guidance for clinicians. Based on randomised trials and systematic reviews published in recent years, there is an urgent need to update the guidelines and consensus documents in terms of topics, for example effectiveness of resistance training and resistance training outcome index.

Lymphatic Phenotype of Noonan Syndrome: Innovative Diagnosis and Possible Implications for Therapy

Dysregulation of the Ras/Mitogen-activated protein kinase (MAPK) signaling pathway is suggested to play a pivotal role in the development of the lymphatic system in patients with Noonan Syndrome (NS). Pathogenic gene variants in the Ras/MAPK pathway can therefore lead to various lymphatic diseases such as lymphedema, chylo-thorax and protein losing enteropathy. Diagnosis and treatment of the lymphatic phenotype in patients with NS remain difficult due to the variability of clinical presentation, severity and, probably, underlying unknown pathophysiologic mechanism. The objective of this article is to give an overview of the clinical presentation of lymphatic disease in relation to central conducting lymphatic anomalies (CCLA) in NS, including new diagnostic and therapeutic options. We visualized the central conducting lymphatic system using heavily T2-weighted MR imaging (T2 imaging) and Dynamic Contrast-enhanced MR Lymphangiography (DCMRL) and compared these results with the lymphatic clinical presentation in seven patients with NS. Our results show that most patients with NS and lymphatic disease have CCLA. Therefore, it is probable that CCLA is present in all patient with NS, presenting merely with lymphedema, or without sensing lymphatic symptoms at all. T2 imaging and DCMRL can be indicated when CCLA is suspected and this can help to adjust therapeutic interventions.

Manual lymphatic drainage with or without fluoroscopy guidance did not substantially improve the effect of decongestive lymphatic therapy in people with breast cancer-related lymphoedema (EFforT-BCRL trial): a multicentre randomised trial

When added to decongestive lymphatic therapy (DLT), what is the effect of fluoroscopy-guided manual lymphatic drainage (MLD) versus traditional MLD or placebo MLD for the treatment of breast cancer-related lymphoedema (BCRL)?

DESIGN

Multicentre, three-arm, randomised controlled trial with concealed allocation, intention-to-treat analysis and blinding of assessors and participants.

PARTICIPANTS

At five hospitals in Belgium, 194 participants with unilateral chronic BCRL were recruited.

INTERVENTION

All participants received standard DLT (education, skin care, compression therapy and exercises). Participants were randomised to also receive fluoroscopy-guided MLD (n = 65), traditional MLD (n = 64) or placebo MLD (n = 65). Participants received 14 sessions of physiotherapy during the 3-week intensive phase and 17 sessions during the 6-month maintenance phase. Participants performed self-management on the other days.

OUTCOME MEASURES

All outcomes were measured: at baseline; after the intensive phase; after 1, 3 and 6 months of maintenance phase; and after 6 months of follow-up. The primary outcomes were reduction in excess volume of the arm/hand and accumulation of excess volume at the shoulder/trunk, with the end of the intensive phase as the primary endpoint. Secondary outcomes included daily functioning, quality of life, erysipelas and satisfaction.

RESULTS

Excess lymphoedema volume decreased after 3 weeks of intensive treatment in each group: 5.3 percentage points of percent excessive volume (representing a relative reduction of 23.3%) in the fluoroscopy-guided MLD group, 5.2% (relative reduction 20.9%) in the traditional MLD group and 5.4% (relative reduction 24.8%) in the placebo MLD group. The effect of fluoroscopy-guided MLD was very similar to traditional MLD (between-group difference 0.0 percentage points, 95% CI -2.0 to 2.1) and placebo MLD (-0.2 percentage points, 95% CI -2.1 to 1.8). Fluid accumulated at the shoulder/trunk in all groups. The average accumulation with fluoroscopy-guided MLD was negligibly less than with traditional MLD (-3.6 percentage points, 95% CI -6.4 to -0.8) and placebo MLD (-2.4 percentage points, 95% CI -5.2 to 0.4). The secondary outcomes also showed no clinically important between-group differences.

CONCLUSION

In patients with chronic BCRL, MLD did not provide clinically important additional benefit when added to other components of DLT.

Update to the Canadian clinical practice guideline for best-practice management of breast cancer-related lymphedema: study protocol

BACKGROUND

One of the more frequent complications following treatment for breast cancer, lymphedema is a substantial swelling of the arm, breast and chest wall that occurs on the side where lymph nodes were removed. The aim of this work is to update recommendations on the prevention, diagnosis and management of lymphedema related to breast cancer.

METHODS

We present the protocol for an update of the 2001 clinical practice guideline on lymphedema from the Steering Committee for Clinical Practice Guidelines for the Care and Treatment of Breast Cancer. We will use a patient-oriented research approach with a focus on self-management and the positive health model to inform the updated guideline development. The methods proposed will be undertaken with consideration of the standards outlined in the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. The literature will be appraised by evaluating existing guidelines from other countries, the evidence from systematic reviews and meta-analyses and direct evidence from clinical studies. We will manage competing interests according to Guidelines International Network principles. Recommendations will be presented using an actionable statement format and will be linked to the level of evidence along with any relevant considerations used in formulation. A draft of the guideline will be produced by the steering committee then sent out to international experts and stakeholder groups for feedback.

INTERPRETATION

The primary benefit of this clinical guideline will be to improve the quality of care of women with breast cancer-related lymphedema. Findings will be disseminated at national and international conferences and through webinars and educational videos hosted on the websites of the supporting organizations.

The Effect of a Low-Carbohydrate, High-Fat Diet versus Moderate-Carbohydrate and Fat Diet on Body Composition in Patients with Lipedema

INTRODUCTION

Lipedema is a disorder characterized by an excessive accumulation of subcutaneous body fat, mainly bilateral and symmetrical accumulation of fat deposits, particularly in the lower extremities excluding feet. Pain (spontaneous or with palpation) and increased capillary fragility with bruising are also part of clinical presentation. It is estimated to occur in approximately 11.0% of women worldwide. Management of obesity among patients with lipedema is a key component in its treatment.

PURPOSE

The aim of this study was to compare effectiveness of two diets: low-carbohydrate-high-fat diet (LCHF) and medium-fat-medium-carbohydrate diet (MFMC) in body weight, body fat and limb circumference reduction in patients with lipedema.

MATERIAL AND METHODS

The studied women (n = 91) were divided into 2 groups and submitted to 1 of the 2 diets for 16 weeks. Anthropometric measurements such as body height [cm], body weight [kg], body fat percentage [%], body fat [kg], lean body mass [kg], and visceral fat level were collected at the beginning and end of the study.

RESULTS

We have not found any significant differences in anthropometric measurements at the baseline between groups. Body weight and all anthropometric parameters decreased significantly in both groups after 16 weeks of diets, excluding the circumference above the right ankle for the MFMC diet which did not change. The LCHF diet contributed to reduction of body weight (-8.2 ± 4.1 kg vs -2.1 ± 1.0 kg; p < 0.0001), body fat (-6.4 ± 3.2 kg vs 1.6 ± 0.8 kg; p < 0.0001), waist (-7.8 ± 3.9 cm vs -2.3 ± 1.1 cm; p < 0.0001), hips (-7.4 ± 3.7 cm vs -2.5 ± 1.3 cm; p < 0.0001), thighs and calves' circumferences compared with the MFMC diet. We observed reduction of pain in the extremities and mobility improvement in LCHF group (data not shown).

CONCLUSION

The LCHF diet was more effective than MFMC in body weight, body fat and lower limb circumferences reduction.

Primary lymphoedema

Lymphoedema is the swelling of one or several parts of the body owing to lymph accumulation in the extracellular space. It is often chronic, worsens if untreated, predisposes to infections and causes an important reduction in quality of life. Primary lymphoedema (PLE) is thought to result from abnormal development and/or functioning of the lymphatic system, can present in isolation or as part of a syndrome, and can be present at birth or develop later in life. Mutations in numerous genes involved in the initial formation of lymphatic vessels (including valves) as well as in the growth and expansion of the lymphatic system and associated pathways have been identified in syndromic and non-syndromic forms of PLE. Thus, the current hypothesis is that most cases of PLE have a genetic origin, although a causative mutation is identified in only about one-third of affected individuals. Diagnosis relies on clinical presentation, imaging of the structure and functionality of the lymphatics, and in genetic analyses. Management aims at reducing or preventing swelling by compression therapy (with manual drainage, exercise and compressive garments) and, in carefully selected cases, by various surgical techniques. Individuals with PLE often have a reduced quality of life owing to the psychosocial and lifelong management burden associated with their chronic condition. Improved understanding of the underlying genetic origins of PLE will translate into more accurate diagnosis and prognosis and personalized treatment.

Pressure Curves, Static and Dynamic Stiffness of Different Two-Component Compression Systems for the Treatment of Chronic Edema of the Lower Limbs

Background: Compression is a cornerstone modality in edema treatment. Different types of bandages are available in clinical practice. Short-stretch bandages are commonly used; however, newer technologies such as the two-component compression system are available as well. This study assesses the pressure curves and static and dynamic stiffness (Static Stiffness Index [SSI] and Dynamic Stiffness Index [DSI]) of two different two-component compression systems, Coban and CoFlex, for edema treatment. Methods and Results: For this prospective cohort study, 12 healthy volunteers were recruited. The healthy volunteers wore both two-component compression systems for 48 hours. Pressure sensors (PicoPress^®; Microlab, Italy) were placed at 10 and 25 cm above the internal malleolus and 10 pressure readings were used to obtain pressure curves. The SSI and DSI were assessed. Additionally, comfort (ICC compression questionnaire) and adverse events were assessed as well. Both two-component compression systems exert a sufficient amount of sub-bandage pressure, although CoFlex exerts systematically significantly lower pressure in comparison with Coban. This difference in sub-bandage pressure remains constant over 48 hours. Both two-component compression systems are sufficiently stiff (stiffness >15 mmHg) and remain stiff over time. Conclusions: Both two-component compression systems have pressure curves that are high enough to motivate their use in the treatment of chronic edema. Additionally, both systems were found to be comfortable and have clinically effective SSI and DSI values.

Sensory signs and symptoms in women with self-reported breast cancer-related lymphedema: a case-control study close up

PURPOSE

It is not clear to what extent signs and symptoms other than arm swelling, including pain, altered sensory function, and body perception disturbances, differ between women with measurable and non-measurable breast cancer-related lymphedema (BCRL). A case-control study was performed to compare these signs and symptoms between (1) women with self-reported BCRL with objectively measurable swelling; (2) women with self-reported BCRL without objective confirmation; and (3) a control group with no self-reported BCRL.

METHODS

The three groups were compared for (1) the severity of self-reported signs and symptoms of BCRL, (2) problems in functioning related to BCRL, (3) pain-related outcomes, (4) sensory functions, and (5) body perception.

RESULTS

All self-reported outcomes related to signs and symptoms of BCRL and problems in functioning were significantly different between the control group and the other two groups with and without measurable self-reported BCRL (p < 0.001-0.003). Except for "skin texture" (p = 0.01), no differences were found between groups. For pain-related outcomes, sensory function, and body perception, significant differences were found for the mechanical detection threshold (p < 0.01) and self-reported disturbances in body perception (p < 0.001) between the self-reported BCRL groups and control group.

CONCLUSIONS

Diverse signs and symptoms related to BCRL, sensory function, and perception were different among women with self-reported BCRL compared to controls. No differences between women with and without measurable self-reported BCRL were found.

IMPLICATIONS FOR CANCER SURVIVORS

The presence of self-reported BCRL, with or without measurable swelling, is a first indication for the need of further diagnostic evaluation.

Relation Between Early Disturbance of lymphatic transport Visualized With Lymphofluoroscopy and Other Clinical Assessment Methods in Patients With Breast Cancer

INTRODUCTION

Lymphedema of the upper extremity is one of the most feared complications following breast cancer treatment. Lymphofluoroscopy is a sensitive instrument for detection of lymphedema and visualization of superficial lymphatic transport, thus suitable for early detection. Early detection of lymphedema is important as it can prevent lymphedema to progress into more severe stages and minimalize impact on quality of life and medical costs.

OBJECTIVE

To determine agreement between the presence of early disturbance of the lymphatic transport and outcome of clinical measurement tools evaluating the development of lymphedema.

METHODS

A prospective study was conducted in 128 breast cancer patients scheduled for breast cancer surgery. Patients were evaluated before surgery and 1, 3-, 6-, 9-, and 12-months' post-surgery. Cohen's Kappa was used to determine agreement between presence of early disturbance in lymphatic transport and presence of pitting/increased skinfold thickness/increased Percentage Water Content ratio (PWC)/increased arm-hand volume (circumference measures and water displacement).

RESULTS

For pitting status (Kappa 0.23), for skinfold thickness (Kappa 0.29) and the PWC ratio (Kappa 0.21) a minimal agreement was found. The circumference measurement had a minimal agreement for 5% volume difference (Kappa 0.22) and no agreement for 3% volume difference (Kappa 0.19). Sensitivity was weak for all clinical assessments. The specificity was excellent for pitting status, skinfold thickness, PWC ratio, and for 5% volume difference. For 3% a high specificity was found.

CONCLUSION

The clinical tools assessed in this study were not able to predict an early disturbance of the lymphatic transport seen on lymphofluoroscopy.

Shaving Technique and Compression Therapy for Elephantiasis Nostras Verrucosa (Lymphostatic Verrucosis) of Forefeet and Toes in End-Stage Primary Lymphedema: A 5 Year Follow-Up Study in 28 Patients and a Review of the Literature

Background. Longstanding lymphedema can lead, especially when there is recurrence of erysipelas, to irreversible elephantiasis nostras verrucosa (ENV). This predisposes to new episodes of erysipelas, leading to further damage of the lymphatics and deterioration of the lymphedema as a whole. We report the results of 28 patients with primary lymphedema and surgical removal ENV of the forefoot and toes treated between 2006 and 2014. Method: Retrospective descriptive 5 year follow-up study of 28 patients with various diagnosis of primary lymphedema. Wound healing time, number of erysipelas, body mass index (BMI), recurrence of EVN and types of compression were documented during follow-up. Results: After preoperative multidisciplinary work up, operation of the toes with shaving and excision was performed within a conservative treatment program. During the follow up, the number of erysipelas attacks decreased dramatically (mean 17.6 vs. 0.6). Before treatment, no toecaps were used; and in follow up, it was a part of treatment. Recurrence of ENV was not observed. Compared to the literature with often BMI > 35, the mean BMI in our group was 30.0 (overweight). In 12 patients, we concurrently performed circumferential suction-assisted lipectomy for end-stage lymphedema of the leg. Conclusion: Although lymphedema patients are treated with garments during the maintenance phase, compression of the toes is often too challenging. Surgical removal of the verrucosis of toes is an effective therapeutic modality as part of an integrated lymphedema treatment program to restore the shape of the toes and enable the wearing of toecaps. This technique can also be effective for ENV of origins other than primary lymphedema. Although ENV is a generally accepted term, it can have undesirable connotations. We suggest using a more inclusive name such as lymphostatic verrucosis, because long-lasting lymphatic impairment is involved in all ENV and the term verrucosis is above discussion.

Prognostic factors for lymphedema in patients with locally advanced head and neck cancer after combined radio(chemo)therapy- results of a longitudinal study

AIM

Treatment-associated lymphedema is a common side effect after multimodal therapy for locally advanced head and neck cancer (LAHNC). This study aims to evaluate potential prognostic factors for head and neck lymphedema (HNL) and its potential impact on clinical outcome.

METHODS

This is a prospective data registry analysis on 280 patients treated for locally advanced head and neck cancer (LAHNC). All patients received surgery and risk-adapted platinum-based adjuvant intensity modulated radio(chemo)therapy (R(C)T, IMRT). Treatment- related toxicity was prospectively registered in a data base in regular intervals (baseline 3 months after R(C)T, every 3 months for 3 years, and every 6 months thereafter) and documented according to RTOG/EORTC toxicity criteria.

RESULTS

Predictive for any grade HNL 3 months after R(C)T were age, BMI, number of removed nodes and RT modality. Multivariable logistic regression analysis showed that in the acute toxicity phase (3 months after R(C)T) higher body mass index (BMI), extracapsular spread (ECE), linac-based IMRT, bilateral treatment to the neck (surgery and RT), and the addition of chemotherapy increase the risk for grade 2 HNL. For chronic HNL, higher BMI, linac-based IMRT and ECE were predictive for grade 2 HNL. Higher BMI is associated with better local control rates. Advanced age and ECE had a negative impact on OS.

CONCLUSION

HNL is a common acute and late side effect after multimodal therapy for LAHNC. Knowing risk factors for HNL prior to therapy enables caregivers and patients to take measures prior to treatment to prevent or limit the effects of HNL.

A methodologic assessment of lymphedema clinical practice guidelines

OBJECTIVE

The objective of this review was to determine the methodologic quality of current lymphedema clinical practice guidelines (CPGs) to assist health care professionals in selecting accessible, high-quality guidance and to identify areas for improvement in future CPGs.

METHODS

MEDLINE, Embase, online CPG databases, and reference lists of included guidelines were searched up to January 31, 2020. Full-text CPGs reporting on evidence-based recommendations in lymphedema diagnosis or management in English were included. CPGs based on expert consensus, CPG summaries, or CPGs that were not freely available were excluded. Two reviewers identified eligible CPGs, extracted data, and assessed their quality independently using the Appraisal of Guidelines for Research and Evaluation II instrument. Significant scoring discrepancies were discussed with a third reviewer. An overall scaled quality score of ≥80% was the threshold to recommend guideline use.

RESULTS

Six relevant CPGs were identified. One was subsequently excluded as its full text could not be obtained. Overall, there was very good inter-reviewer reliability of scores with intraclass correlation coefficient of 0.952 (95% confidence interval, 0.921-0.974). No single CPG scored highest in all domains, with methodologic heterogeneity observed. Poor performance was noted in domain 5 (mean scaled score, 23.8% ± 17.1%) and domain 6 (22.9% ± 26.7%). No CPG achieved an overall scaled quality score of ≥80%, with the top CPG scoring 79.2%.

CONCLUSIONS

According to the defined threshold, no lymphedema CPG was considered adequate for use in clinical practice. All current lymphedema CPGs have areas for improvement with elements of methodologic quality lacking, particularly with respect to rigor of development. A structured approach, guided by the use of CPG creation tools and checklists such as the Appraisal of Guidelines for Research and Evaluation II instrument, should help CPG development groups in improving the quality of future CPGs. This is of particular importance in a complex, multidisciplinary condition such as lymphedema.

A systematic review of guidelines for lymphedema and the need for contemporary intersocietal guidelines for the management of lymphedema

OBJECTIVE

Lymphedema (LED) affects an estimated 35 million patients in the United States and a staggering 140,200 million people worldwide, yet LED is the forgotten vascular disease. Whereas the diagnosis and treatment of arterial and venous diseases have been strengthened by the development of clinical practice guidelines (CPGs), few CPGs are available for LED. Moreover, for CPGs to have their greatest impact, they should be both of high quality and developed using the most rigorous evidence-based methods. We performed a systematic review of the available CPGs for LED, which were assessed for breadth of content and methodologic strength.

METHODS

A literature search was conducted from National Guideline Clearinghouse (www.

GUIDELINES

gov), BMJ Clinical Evidence (http://clinicalevidence.bmj.com), and National Institute for Health and Care Excellence (http://www.nice.org.uk) as well as from MEDLINE and Google, which selected 245 documents. After a horizon scan that identified 13 potential CPGs, 4 satisfied the criteria for LED. These were analyzed for inclusion of key elements of diagnosis and treatment.

RESULTS

A horizon scan (abstract review) of the 245 documents identified 10 potential CPGs. Of the 10 documents, 6 claimed to be CPGs, but 2 were limited in scope (rehabilitation or compression only), 2 were consensus statements, 1 was a position statement, and 1 was a systematic review. This process yielded four CPGs: Lymphedema Framework Best Practice for the Management of Lymphedema; Japanese Lymphedema Study Group-A Practice Guideline for the Management of Lymphedema; Clinical Resource Efficiency Support Team Guidelines for the Diagnosis, Assessment and Management of Lymphedema; and Guidelines of the American Venous Forum. Only one of four CPGs was based on a contemporary systematic review (2016 end date of references), whereas the remainder had older systematic reviews (end dates of 2005, 2007, and 2007). Several areas of contemporary diagnosis, treatment, and monitoring of LED were absent.

CONCLUSIONS

This systematic review of available LED CPGs demonstrates a limited number of guidelines. The four CPGs identified lack contemporary references while demonstrating low overall study quality. Therefore, it is imperative for our vascular societies to develop contemporary high-quality evidence-based CPGs for LED, as they have for other vascular diseases.

Reliability and validity of a Dutch Lymphoedema Questionnaire: Cross-cultural validation of the Norman Questionnaire

OBJECTIVE

To perform the cross-cultural validation process of the Dutch Norman Questionnaire (NQ), a questionnaire for the detection and characterisation of breast-cancer related lymphoedema (BCRL) using self-reported signs and symptoms.

METHODS

Test-retest reliability and construct (including convergent, divergent and known-groups validity), face and content validity were examined in breast cancer patients with (n = 30) and without (n = 30) lymphoedema. For concurrent validity, first, agreement between the diagnostic item of the NQ and a clinical diagnosis were analysed. Second, correlations between NQ scores and clinical arm volume assessment were tested.

RESULTS

Test-retest reliability was found to be strong to very strong (ICC 0.79-0.96) in the lymphoedema group and moderate to very strong ( ICC 0.64-0.99) in the non-lymphoedema group. Seventeen out of 20 hypotheses on convergent and divergent validity were accepted. There was good face, content and known-groups validity as well. For concurrent validity, agreement between evaluation methods was only 0.462. Moderate correlations were found between 6 out of 9 symptom scores (r = 0.422-0.630) of the NQ and clinical assessment.

CONCLUSION

The Dutch NQ is a reliable and valid questionnaire for the characterisation of BCRL using self-reported signs and symptoms. Only moderate agreement for the detection of BCRL was found.

Role of Bioelectrical Impedance Analysis in the Evaluation of Patients with Upper Limb Lymphedema

Background: Monofrequency bioelectrical impedance analysis (BIA) protocols seek to further quantify changes in lymphedema compared with traditional circumferential evaluations. Complex decongestive therapy (CDT) is an effective method of reducing unilateral upper limb lymphedema secondary to breast cancer treatments. Comparing lymphedema measurements between segmental tetrapolar BIA, total body BIA, and circumferential measurements during therapeutic changes can improve our quantitative assessment ability for this prevalent medical complication. Methods and Results: Twenty-two patients with breast-cancer-related unilateral upper limb lymphedema participated in this prospective observational study. Circumferential measurements, segmental tetrapolar BIA, and total body BIA were obtained and compared before CDT, immediately after 10 sessions of CDT, and 30 days post-CDT to assess lymphedema. The segmental tetrapolar BIA correlated well with improvements in circumferential measurements of the limb. We found that the resistance value cutoff point of 237 Ω could indicate a recurrence of lymphedema. Conclusions: Segmental, tetrapolar monofrequency BIA provides a simple method to monitor and evaluate the efficacy of therapy in the outpatient setting by operators with minimal training. This protocol could aid quantitative evaluations of unilateral upper limb lymphedema.

[Differential diagnostics of lipedema and lymphedema : A practical guideline]

Lipedema is a symmetrical disorder of the subcutaneous adipose tissue that affects almost exclusively women in postpubescent age. The trinity of disfiguring hyperplastic adipose tissue of the proximal extremities, increasing pain over time and bruising is characteristic. Lymphedema can occur in both sexes and is differentiated into primary and secondary subtypes. Symmetry is not a prerequisite for diagnosis. Characteristic for lymphedema is the disproportion between lymphatic fluid and the capacity of lymphatic vessels. The most distal body parts are always more severely affected than proximal parts. In the initial phases lymphedema is painless but in advanced stages tension pain can occur. The combination of both disorders has been described; however, lipedema is not responsible for subsequent lymphedema in contrast to central obesity, which significantly increases the risk of lymphedema. The differential diagnosis is of utmost importance for a meaningful management.

Global guidelines trends and controversies in lower limb venous and lymphatic disease: Narrative literature revision and experts' opinions following the vWINter international meeting in Phlebology, Lymphology & Aesthetics, 23-25 January 2019

Guidelines are fundamental in addressing everyday clinical indications and in reporting the current evidence-based data of related scientific investigations. At the same time, a spatial and temporal issue can limit their value. Indeed, variability in the recommendations can be found both among the same nation different scientific societies and among different nations/continents. On the other side, Garcia already published in 2014 data showing how, after three years in average, one out of five recommendations gets outdated (Martinez Garcia LM, Sanabria AJ, Garcia Alvarez E, et al. The validity of recommendations from clinical guidelines: a survival analysis. CMAJ 2014;186(16):1211–1219). The present document reports a narrative literature revision on the major international recommendations in lower limb venous and lymphatic disease management, focusing on the different countries’ guidelines, trends and controversies from all the continents, while identifying new evidence-based data potentially influencing future guidelines. World renowned experts’ opinions are also provided. The document has been written following the recorded round tables scientific discussions held at the vWINter international meeting (22–26 January 2019; Cortina d’Ampezzo, Italy) and the pre- and post-meeting literature search performed by the leading experts.

Tackling the diversity of breast cancer related lymphedema: Perspectives on diagnosis, risk assessment, and clinical management

Breast cancer related lymphedema (BCRL) develops as a consequence of surgical treatment and/or radiation therapy in a significant number of breast cancer patients. The etiology of this condition is multifactorial and has not yet been completely elucidated. Risk factors include high body mass index, radical surgical procedures (i.e. mastectomy and axillary lymph node dissection), number of lymph nodes removed and number of metastatic lymph nodes, as well as nodal radiation, and chemotherapy. However, these predisposing factors explain only partially the BCRL occurrence, suggesting the possible involvement of individual determinants. Despite the implementation of conservative approaches, BCRL still remains in a proportion of cases an incurable and progressive condition with major physical and psychological implications. To date, diagnostic methods and staging systems lack uniformity, leading to a possible underestimation of the real incidence of this condition, decreasing early detection and thus the possibility of an effective treatment. Several preventive and therapeutic options are available, both conservative and surgical, but are not included in a standardized intervention protocol, tailored on patient's specific characteristics. In this review, we provide a comprehensive overview of the current state-of-knowledge of BCRL management, novel advantages in the assessment of pre-operative evaluation and risk prediction and discuss strengths and weaknesses of diagnostic and treatment strategies currently accessible in clinical practice.
