Lymphoedema management: An international intersect between developed and developing countries.Similarities, differences and challenges

A Method to Improve the Accuracy for the Comparison of Consecutively Determined Upper Limb Cross-Sectional Area Profiles of Test Subjects: Impact on (Segmental) Limb Volume and Local Limb Circumference

Background: Chronic edema management depends on measuring small volume changes over time. Therefore, a highly sensitive, accurate, and reliable technique is needed to objectively judge sequential measurements. Methods and Results: The prototype of the Peracutus Aqua Meth (PAM), a new volumetric measuring device, was used in an experimental study. Thirty-nine healthy test subjects were measured three times. The measuring principle of the PAM is based on obtaining a profile of cross-sectional areas along the length of an object or limb. Besides total arm volumes, the volume of any chosen segment can be determined. The utmost tip of the middle finger appeared to be an unreliable reference point. Instead, the concept of "hand median" was introduced to align and compare profiles of cross-sectional areas of sequential measurements. Using the hand median strongly improved the measuring accuracy, rendering standard deviation values of 0.4%-1.3% for (segmental) volume determination. Conclusions: Measurements with the PAM show that accurate local/segmental volume determination of a limb is possible. Standard deviations of less than 1.3% are easily obtained for cross-sectional area and volume determination.

Multi-Stage Surgical Debulking for Advanced Lower Limb Lymphedema: Achieving Cosmetic and Functional Success

Lymphedema, characterized by impaired lymphatic drainage, presents in primary and secondary forms, causing limb enlargement and other complications. Management involves a multidisciplinary approach, with manual lymphatic drainage and surgery as key interventions. Treatment aims to improve quality of life, with surgical debulking showing positive outcomes, as demonstrated in a case of severe lower limb lymphedema. A 40-year-old male with severe congenital lymphedema praecox presented with left lower extremity swelling and cellulitis. Despite previous unsuccessful surgery, subsequent debulking surgeries over nine months improved function and appearance. Biopsies confirmed lymphedema praecox diagnosis. Lymphedema poses significant challenges, often requiring surgical intervention such as the Charles procedure, which involves surgically removing skin and soft tissue layers down to the deep fascia in the affected limb, with the excised skin repurposed as a graft for coverage, in severe cases. However, milder cases may go unnoticed, leading to delayed treatment. Our patient experienced advanced lymphedema, necessitating a staged surgical approach to minimize risks and enhance outcomes. This strategy successfully managed blood loss and improved cosmetic results, ultimately improving the patient's quality of life. Lymphedema poses complex challenges, with tailored treatments such as staged procedures essential for optimal outcomes. Our case emphasizes the need for careful consideration and patient counseling, highlighting the value of strategic management approaches. By minimizing risks and optimizing outcomes, we aim to enhance the quality of life for individuals with lymphedema, underscoring our commitment to ongoing improvement in patient care.

Integrated lymphoedema and tissue viability service: improving patient and wound outcomes

This article will focus on the integration of tissue viability and lymphoedema services to improve outcomes for patients with leg ulceration. It will highlight why there is a need for lymphoedema specialist knowledge within the care of patients with leg ulceration and how the services are closely aligned. Lymphoedema can adversely affect wound healing and the article will provide case studies that highlight how developing a hybrid tissue viability and lymphoedema clinician or integration of the specialists can provide effective patient-centred care at reduced cost. The article offers potential strategies and suggestions on how to address inequalities in care and how to improve service provision.

Staged surgical management of advanced leg lymphedema: A successful Charles procedure in a resource-limited setting, case report

INTRODUCTION

Lymphedema, marked by localized tissue swelling, poses a worldwide challenge. In sub-Saharan Africa, where patients often present in advanced stages, resectional techniques such as the Charles procedure become the sole option. This case report illustrate the staged surgical approach to address extensive lower limb lymphedema through the utilization of the Charles procedure.

CASE PRESENTATION

A 38-year-old female with a 20-year history of right leg lymphedema underwent a three-stage surgical plan. The first stage involved partial excision of lymphedema mass, the second stage focused on debulking of the rest of the mass and skin advancement, and the third stage comprised a meshed split-thickness skin graft. Despite complications, including necrosis and infection, the patient was discharged after 60 days with significant improvement in quality of life.

DISCUSSION

In resource-constrained settings, strategic staging and careful perioperative planning are vital for mitigating risks. The presented case underscores the successful utilization of the Charles procedure in sub-Saharan Africa, addressing advanced lymphedema and improving patient outcomes.

CONCLUSION

The Charles procedure, despite its risks, proves to be a viable option for advanced lymphedema in regions with limited resources. Meticulous staging and perioperative planning play a pivotal role in achieving positive outcomes, enhancing the quality of life for patients in resource-constrained settings.

Modified Seki Method for the Treatment of Lymphedema

Lymphedema is characterized by the abnormal accumulation of lymphatic fluid in the skin and subcutaneous tissue owing to impaired lymph flow. This condition may be primary or secondary to other diseases. Most lymphedema occurs in the lower extremities, which greatly interferes with the activities of the patients, especially walking. Further, it may affect the psychological condition of patients. In Indonesia, several patients with severe lymphedema have visited our clinic. In our center, lymphography is not available. However, as our center is a provincial referral hospital, many patients with lymphedema present with severe conditions. Nonoperative and operative treatment is available, including lymphovenous anastomosis. Herein, we present the rare case of a 33-year-old man with severe lymphedema in his left leg for the past 7 years. The patient was diagnosed with stage III secondary lymphedema of the left lower extremity and underwent lymphaticovenular anastomosis using a modification of the Seki method (Seki 2015). Five large lymphatic vessels were identified using methylene blue, and a transverse incision was made approximately 2-3 cm from the skin to the fatty tissue under the superficial fascia. Lymphaticovenular anastomosis was performed using a microscope. On postoperative day 1, the edema in the leg shrank significantly, and 6 months after surgery, the patient's foot size began normalizing. The patient could wear pants and became more confident.

Practice points for lymphoedema care in low- and middle- income countries developed by nominal group technique

BACKGROUND

Lymphoedema is a common, distressing, and debilitating condition affecting more than 200 million people globally. There is a small body of evidence to guide lymphoedema care which underpins several lymphoedema clinical practice guidelines developed for high-income countries (HIC). Some of these recommendations are unlikely to be feasible in low-resource settings.

AIM

To develop practice points for healthcare workers that optimise lymphoedema care in low- and middle-income countries (LMIC).

METHODS

A nominal group technique (NGT) was undertaken to gain consensus on which content from HIC guidelines was important and feasible to include in practice points for LMIC, and other important advice or recommendations. Participants included experts, clinicians, and volunteers involved in lymphoedema care in LMIC. The NGT followed five key stages: silent 'ideas' generation, round-robin rationale, clarification, refinement and verification. The first, fourth and fifth stages were completed via email, and the second and third during a video meeting in order to generate a series of consensus based prevention, assessment, diagnosis, and management of lymphoedema in LMIC practice points.

RESULTS

Of sixteen participants invited, ten members completed stage 1 of the NGT (ideas generation), of whom six contributed to stages 2 (round-robin) and 3 (clarification). All those who completed stage 1 also completed stages 4 (refinement) and 5 (verification). Practice points unanimously agreed on included Complex Decongestive Therapy (CDT) and good skin care, with management to be determined by lymphoedema stage. For podoconiosis-endemic areas, the use of socks and shoes was identified as very important in the prevention of non-filarial lymphoedema and other lymphoedema-causing conditions. Participants indicated that diagnosing lymphoedema using the lymphoscintigraphy and Indocyanine green (ICG) fluorescent lymphography was not possible due to unavailability and cost in LMIC. Surgical procedures for lymphoedema management were unanimously eliminated due to the unavailability of technology, limited workforce, and expensive cost in LMIC.

CONCLUSION

The consensus-based practice points generated by this project provide healthcare workers with guidance on caring for people with lymphoedema in LMIC. Further development of workforce capacity is needed.

Improving care for cancer-related and other forms of lymphoedema in low- and middle-income countries: a qualitative study

BACKGROUND

Lymphoedema is a common, distressing and debilitating condition that can be related to cancer and its treatment or other conditions. Little is known about current practices in the diagnosis, assessment and management of lymphoedema in low- and middle-income countries (LMIC).

AIM

To describe current practices in diagnosing, assessing and managing cancer-related and other forms of lymphoedema in LMIC, and related barriers and facilitators.

METHODS

An exploratory-descriptive qualitative study. Participants were lymphoedema experts or health care professionals identified via published lymphoedema papers and professional organizations respectively. Sampling was purposive to ensure a diversity of perspectives and experience. Data collection was via semi-structured telephone/video interviews, and questions canvassed participants' experiences and perceptions of lymphoedema care in LMIC. Interviews were audio-recorded and transcribed verbatim. Analysis proceeded via inductive coding before mapping codes to the World Health Organization's (WHO) Innovative Care for Chronic Conditions Framework.

RESULTS

Nineteen participants were interviewed, most of whom were physiotherapists (n = 11). Ten participants worked permanently in a LMIC, while the remainder were based in a high-income country (HIC) and had been involved in initiatives to improve lymphoedema care across multiple LMIC. Participants indicated that management of cancer versus non-cancer related lymphoedema was similar, but that pathways to care were more straight-forward for those receiving cancer care, leading to earlier diagnosis. Key facilitators to optimizing lymphoedema care in LMIC included: 1) joining forces to overcome lymphoedema-related stigma; 2) building workforce capabilities; and 3) partnering with patients and families to support self-management. Ideas for building workforce included developing health professional knowledge, supporting a commitment to multidisciplinary team care, and adapting HIC guidelines for lymphoedema care to LMIC. Partnering with patients and families to support self-management involved following the person-centred approach, establishing clear communication, promoting adherence to management, adapting management to available resources, and involving patient family and friends in lymphoedema care.

CONCLUSION

Raising community and health professional awareness regarding lymphoedema and its management is a key first step to improving care outcomes. Resources for clinicians and patients/families developed for lymphoedema care in HIC need to be adapted for low resource settings.

Healthcare Practitioners' Knowledge of Lymphedema

Objectives

Lymphedema is neglected in medical education, and a review on healthcare practitioners' (HCPs) knowledge is necessary to shed light on gaps and to provide evidence for establishing educational programs on lymphedema.

Methods

This systematic review was performed based on the PRISMA guideline in PubMed, Scopus, Web of Science, and Google Scholar databases. There was no limitation on the type of lymphedema or HCPs. The quality assessment was performed based on QATSDD. Data regarding study characteristics, questionnaire context, and findings of the study were summarized from each article.

Results

After the screening, 16 articles were included that 12 were cross-sectional, two were qualitative, and two were interventional pilot studies. Breast cancer and other cancer-related lymphedema, lymphatic filariasis, and podoconiosis were included, and the majority of articles were focused on primary HCPs. The overall knowledge was low and average in five and 11 articles, respectively, and prior education was a significant factor related to higher knowledge of lymphedema in two studies.

Conclusion

Structured education of lymphedema is needed to increase the knowledge of HCPs and to enhance their collaboration in multidisciplinary care teams. Improvement of HCPs' knowledge may lead to better outcomes of lymphedema patients' management which are neglected.

Global Knowledge Gaps in Equitable Delivery of Chronic Edema Care: A Political Economy Case Study Analysis

Background: Most existing research in chronic edema (CO) care takes place in high-income countries and is both clinically and medically focused, although often accorded low prestige and status. A myriad of challenges define the problems and important gaps in understanding and translating what we know into sustainable practice. Less considered, however, are the consequences and socioeconomic significance of this "knowledge gap" in an increasingly globalized world. This article seeks to address this lacuna by suggesting a political economy approach across three different income settings, the United Kingdom (high), Kerala in India (middle), and Uganda (low), to learn from international practice and understand the contribution of local (community-specific) health traditions. Methods and Result: We used a comparative case study approach. In the three case studies we demonstrate how particular thinking, sets of power relationships, and resource distributions influence and structure the provision of CO management more generally. We demonstrate how these intertwined and often invisible processes reflect a market-led biomedical hierarchization that focuses on high-interventionist, high-cost approaches that are then imposed on lower income settings. At the same time, low-cost but evidence-based local knowledge innovation in wound and CO care from low- or middle-income countries is neither recognized nor valued. Conclusion: We conclude that unpacking these dynamics is a necessary route to providing a more equitable health delivery accessible for the many rather than the few.

Magnetic resonance lymphangiography: with or without contrast?

Lymphedema is an important medical issue around the world, caused by an anomalous collection of fluid in soft tissue due to congenital malformations or stenosis or obstruction of lymphatic vessels. Magnetic resonance lymphangiography (MRL) is an emerging technique focused on noninvasive or minimally invasive imaging of lymphatics with the goal to diagnose and treat lymphedema. This review will briefly discuss lymphatic imaging starting with lymphography and radionuclide lymphoscintigraphy up to the newest methods, focusing on MRL, a rising technique, and highlighting the technical aspects fundamental for achieving high-resolution MRL.

Estimates for Assessment of Lymphedema: Reliability and Validity of Extremity Measurements

Background: Measuring lymphedema with high accuracy is important for several reasons. The aim of this study was to assess the reliability and validity of three routinely used methods to estimate limb volumes.

Methods and Results: Inverse water displacement, girth measurements, and Perometer measurements were executed. Although standard techniques were used, extra precautions were taken to maximize accuracy within and between observers. Water displacement, and girth and Perometer measurements resulted in standard deviations of 0.7%–0.8%, 0.5%, and 0.4%–1.0%, respectively.

Conclusion: Measuring limb volumes using routine methods is not easy. Even under optimal conditions, the measurements are quite dependent on the observer. For practical situations, an easy, objective, and reliable method is lacking.

Lower limb chronic edema management program: Perspectives of disengaged patients on challenges, enablers and barriers to program attendance and adherence

Background

Chronic edema (CO) is a progressive, physically disfiguring and currently incurable condition. A multifaceted program has been recommended to manage the swelling. However, there is little evidence investigating patients’ perspectives following the program, particularly for those who have poor adherence and/or are disengaged.

Aim

To investigate the perceived challenges faced by disengaged participants with lower limb CO by identifying their enablers and barriers to participating in a Physiotherapy CO program.

Method

An exploratory qualitative approach was used. A purposive sampling strategy was adopted to recruit participants. Those with more than three months swelling and who had low adherence and/or attendance (disengaged) to the CO program were invited to participate. Semi-structured interviews with six participants from a CO clinic in a tertiary hospital were conducted. Data were thematically analyzed and findings in terms of enablers and barriers were subsequently reflected in the light of a theoretical framework.

Results

All six participants were morbidly obese (BMI 47 ± 4 kg/m²) with multiple chronic comorbidities. Enablers and barriers detected included physical, psychological and social factors that interplay to present multidimensional challenges that influence the participants’ adjustment to managing their CO. For the disengaged participants in this study, their under-managed lower limb CO was a progression towards being housebound and having a gradually increasing level of disability.

Conclusion

This study has identified the multidimensional challenges faced by low adherent and/or disengaged participants with lower limb CO to participating in a hospital-based CO program. Perceived enablers and barriers included physical, psychological and social factors. These were mapped using a health behavior change theoretical framework. Understanding these challenges has implications for developing a multidisciplinary approach aimed at enhancing patient engagement and participation in the physiotherapy CO program.

Comparison of Staging Systems to Assess Lymphedema Caused by Cancer Therapies, Lymphatic Filariasis, and Podoconiosis

Background: Lymphedema is a disease of the skin and subcutaneous tissue resulting from a disturbance in lymph flow. Anyone can be affected, and causes include cancer therapy when lymph nodes are removed or irradiated, the parasitic disease lymphatic filariasis, and damage caused by exposure to irritant soils known as podoconiosis. Manifest lymphedema is progressive and a major contributor to disability, stigma, and social isolation for affected people. Although the pathogenesis of connective tissue changes in lymphedema will follow a similar course regardless of the disease of causation, several systems are used to stage progression. Disparity in these staging systems leads to inconsistency in reporting of the severity of lymphedema and prevents meta-analysis of research results. In the global health environment, integrated morbidity management for chronic illness is essential to meet the needs of affected people and to be sustainable for health care systems. Clinical descriptors for staging criteria within each system may assist clinicians in assessment and provide a format for consistency in reporting by lymphedema researchers.

Methods and Results: Lymphedema staging systems used in oncology, filariasis, and podoconiosis settings were reviewed and the assessment techniques, diagnostic procedures, and clinical observations used by each system are described. The most commonly used staging systems are compared to identify similarities, and a matrix approach to lymphedema staging is proposed.

Conclusion: A universal staging system would contribute to more consistent reporting of research on and clinical management of lymphedema arising from multiple causes.

Long-term outcome of lower extremity lymphedema treated with vascularized lymph node flap transfer with or without venous complications

BACKGROUND

Vascularized submental lymph node (VSLN) transfer is an emerging approach for extremity lymphedema. This study investigated the long-term outcome and venous complications of VSLN for unilateral lower extremity lymphedema.

METHODS

Between 2010 and 2018, patients who underwent VSLN for unilateral lower extremity lymphedema were retrospectively evaluated. Patient demographics, operative records, complications, circumferential improvement, and episodes of cellulitis were analyzed. Further comparisons were performed between different types, numbers, and techniques of venous anastomoses.

RESULTS

A total of 75 VSLNs in 70 patients survived, giving a 100% success rate. Six flaps (8%) had venous complications (VC group) and 69 flaps (92%) did not (No-VC group). There were no statistical differences in types, numbers, and techniques of anastomoses between two groups (P = .65, 1, and .56, respectively). At a mean follow-up of 32.0 ± 23.0 months, mean circumferential improvement and episodes of cellulitis between two groups did not statistically differ significantly (P = .31 and .09, respectively).

CONCLUSIONS

VSLN is an effective treatment for lower extremity lymphedema. The types, numbers of veins, and techniques of venous anastomoses did not statistically affect the venous complication rates. Functional outcomes of the VSLNs were not compromised if venous complications were salvaged promptly.

Compression Vest Treatment for Symptomatic Breast Edema in Women Treated for Breast Cancer: A Pilot Study

Background: Lymphedema of the breast/chest wall after breast cancer treatment is often associated with pain and reduced quality of life. We conducted a pilot study to evaluate whether the use of a compression vest reduced symptoms of breast/chest wall edema in breast cancer patients. Methods and Results: This single-center study included patients (n = 25) with symptomatic breast/chest wall edema with a pain score of ≥3 on the Numerical Rating Scales (range 1-10). The patients were instructed to wear a compression vest (Lymphatrex, Class II) for 6 months. Wilcoxon signed-rank tests were used to compare differences in patient-reported pain intensity/severity. Analyses included all patients with available data. In total, 17 (68%) continued to wear their vests for 6 months, whereas the other 8 withdrew prematurely. At baseline, median pain severity (4.9, interquartile range [IQR] 3.6-6.0) and pain interference (4.3, IQR 2.1-5.9) scores were significantly higher compared with pain scores after wearing the compression vest for 6 months (1.8 IQR 1.0-4.8 and 1.4 IQR 0.9-4.4, resp.). Patient-reported breast/chest wall swelling decreased from 92% (n = 22) at baseline to 71% (n = 12) at 6 months. The prevalence of moderate/severe patient-reported breast/chest wall pain declined from 63% (n = 15) at baseline to 18% (n = 3) at 6 months. Physical, emotional, and social functioning improved over time and was comparable to scores of the Dutch reference population. Conclusion: The results of this pilot study suggest that a compression vest could be an acceptable and effective treatment option for patients with painful breast/chest wall edema. In compliant patients, swelling and pain was significantly reduced.

Worldwide assessment of healthcare personnel dealing with lymphoedema

BACKGROUND

Lymphoedema is a pandemic with about 250 million people suffering from this condition worldwide. Lymphatic diseases have considerable public health significance, but yet few professionals are specialised in their management causing a substantial burden on health resources.

AIMS AND OBJECTIVES

This study aims to give an overview of the approximate number of medical professionals, professional societies, institutions and companies dealing with lymphoedema in various countries. Concepts of improvement for current human resources are considered.

METHODS

An online database analysis (Google search engine and PubMed) was carried out for each country of the world. Additionally, relevant congress participant lists as well as member lists of significant medical societies and reports of the World Health Organisation were analysed.

RESULTS

Overall distribution of tertiary level professionals specialised in this field is heterogenous. A decrescent gradient of professionals can be seen between developed and developing countries and between urban and rural areas. Countries in general do not seem to have yet met the current demand for specialists at tertiary level in this field.

CONCLUSIONS

This study intends to draw attention to the current medical coverage gaps due to a low number of lymphoedema specialists at tertiary level. It wishes to start a discussion about structured reimbursement and certification of knowledge and skills that are essential incentives for experts to act as multiplicators and change the lack of care in the mid-term. Current fail prescriptions and evitable disability and sick certificates represent a high financial burden that could be reinvested in a correct management. Policy makers must focus in the two above mentioned essential measures. Medical training and the consequent development of the industry will then naturally take place, as it was the case for other professional groups in the past.

Chronic oedema 'on-the-ground' education programme

The impact of chronic oedema on community nurses' work, the NHS and those directly affected by the condition is immense. As chronic oedema prevalence is projected to rise and financial austerity continues, innovative, sustainable solutions that ensure positive outcomes for patients must be found. This paper reports findings from a focus group (n=3) investigation of the effects of an innovative workplace education intervention designed to enhance community nurses' knowledge for practice in chronic oedema prevention and management in Wales. The main findings indicated that the programme had enhanced community nurses' awareness, knowledge and understanding of chronic oedema management. By enhancing their knowledge base, benefit might be conferred for patients with chronic oedema in terms of improved quality of life, self-efficacy and self-management. However, the magnitude of perceived benefit was variable and contingent on engagement with and support for self-management. Findings indicate the need for a longitudinal study.

Self-Care for Management of Secondary Lymphedema: A Systematic Review

BACKGROUND

Lymphedema is a debilitating and disfiguring sequela of an overwhelmed lymphatic system. The most common causes of secondary lymphedema are lymphatic filariasis (LF), a vector-borne, parasitic disease endemic in 73 tropical countries, and treatment for cancer in developed countries. Lymphedema is incurable and requires life-long care so identification of effective lymphedema management is imperative to improve quality of life, reduce the burden on family resources and benefit the local community. This review was conducted to evaluate the evidence for effective lymphedema self-care strategies that might be applicable to management of all types of secondary lymphedema.

METHODOLOGY/PRINCIPAL FINDINGS

Searches were conducted in Medline, CINAHL and Scopus databases in March 2015. Included studies reported before and after measures of lymphedema status or frequency of acute infections. The methodological quality was assessed using the appropriate Critical Appraisal Skills Program checklist. Descriptive synthesis and meta-analysis were used to evaluate effectiveness of the outcomes reported. Twenty-eight papers were included; two RCTs were found to have strong methodology, and overall 57% of studies were rated as methodologically weak. Evidence from filariasis-related lymphedema (FR-LE) studies indicated that hygiene-centred self-care reduced the frequency and duration of acute episodes by 54%, and in cancer-related lymphedema (CR-LE) home-based exercise including deep breathing delivered significant volume reductions over standard self-care alone. Intensity of training in self-care practices and frequency of monitoring improved outcomes. Cultural and economic factors and access to health care services influenced the type of intervention delivered and how outcomes were measured.

CONCLUSIONS/SIGNIFICANCE

There is evidence to support the adoption of remedial exercises in the management of FR-LE and for a greater emphasis on self-treatment practices for people with CR-LE. Empowerment of people with lymphedema to care for themselves with access to supportive professional assistance has the capacity to optimise self-management practices and improve outcomes from limited health resources.

Successful Management of Severe Unilateral Lower Extremity Lymphedema in an Outpatient Setting

BACKGROUND AND PURPOSE

Non-cancer-related lymphedema is frequently unrecognized until it has advanced and, therefore, presents substantial management challenges. Treatment for lymphedema reflects cancer research and not the distinct complexities of non-cancer-related lymphedema. This case report describes an outpatient intervention for a patient with non-cancer-related unilateral lower extremity lymphedema.

CASE DESCRIPTION

The patient was a 42-year-old woman who was morbidly obese and had left lower extremity chronic stage III lymphedema. Massive disfiguring lymphedema of her lower leg caused chronic wounds, pain, difficulty ambulating, and the inability to lift her leg in transfers. The patient received complete decongestive therapy (CDT) in an outpatient setting.

OUTCOMES

The volume of the patient's leg decreased more than 66%, so that her massive lower leg was transformed to nearly the same size as her unaffected limb. Proper compression management restored independent transfers and pain-free ambulation.

DISCUSSION

Delayed diagnosis and treatment of non-cancer-related lymphedema result in increased severity and impaired mobility, making this a unique, complex condition requiring modifications to CDT in the outpatient setting. This case report demonstrates successful outpatient treatment of a patient with severe unilateral lower extremity lymphedema associated with large wounds and impaired mobility using CDT that was modified to accommodate her complex medical status, transportation barriers, and health insurance availability. Following 23 weeks of physical therapist interventions, the patient's affected lower extremity was the same size as the unaffected lower extremity, and she was independent in ambulation and stair climbing.

Prevention and management of lymphedema after breast cancer treatment

Lymphedema of the arm after breast cancer treatment continues to challenge clinicians worldwide. In this review, we examine the main modalities, both nonsurgical and surgical, to prevent and treat this as yet incurable condition.

The management of secondary lower limb lymphoedema in cancer patients: a systematic review

BACKGROUND

Lower limb lymphoedema is a recognised complication of cancer commonly encountered in palliative care, associated with reduced mobility and poor quality of life.

AIM

To evaluate the available evidence for the treatment of secondary lower limb lymphoedema in patients with malignancies.

DESIGN

A systematic review of the literature.

DATA SOURCES

The MEDLINE, Embase, LILACS, Science Citation Index, Cochrane Databases and conference proceedings for published data from date of inception to July 2014 were searched. Relevant unpublished studies via relevant databases, Internet searches and hand-searches of the bibliographies of relevant papers were performed.

RESULTS

From 1617 citations, 32 papers were selected for full-text assessment. Two randomised trials and five observational studies were identified. The two randomised controlled trials evaluated graded compression stockings and Coumarin capsules, respectively. The five observational studies evaluated lymphovenous microsurgical shunts, pneumatic compression devices, compression bandages alone, manual lymphatic drainage with compression and a herbal remedy combining Coumarin, Ginkgo and Melitoto (with or without manual lymphatic drainage), respectively. The extracted studies showed substantial heterogeneity. Hence, a meta-analysis was inappropriate and not performed.

CONCLUSION

Few studies have evaluated the clinical effectiveness and potential side effects of treatments for lower limb lymphoedema. Moreover, symptoms and quality-of-life assessments were inconsistently reported. All included studies report lower limb volume reduction after treatment, which includes complex decongestion therapy, graded compression stockings and lymphovenous microsurgical shunts. Adequately powered randomised controlled trials of these interventions are recommended. Effort should be made to establish standardised outcomes, to minimise bias and to improve reporting quality in future trials of treatment for lower limb lymphoedema.

Assessment of the interstitial fluid in the subcutaneous tissue of healthy adults using ultrasonography

OBJECTIVE

Lymphoedema involves swelling, especially in the subcutaneous tissues. For lymphoedema management to be successful, it is necessary to remove the interstitial fluid. Subcutaneous echogenicity may be associated with interstitial fluid, but echogenicity is not an indicator for the evaluation of management because we do not directly compare echogenicity with the interstitial fluid. We aimed to identify an outcome indicator for the evaluation of interstitial fluid using ultrasonography. We assessed the correlation between echogenicity and transverse relaxation rate (R2) on magnetic resonance imaging.

METHODS

This was an observational study. Healthy adults with leg swelling after activity for >8 h were recruited. The legs of 13 women were evaluated using ultrasonography, magnetic resonance imaging and measurements of the limb circumference before and after an intervention to reduce the swelling.

RESULTS

Echogenicity in the oedema group was greater than that of the controls. Echogenicity decreased with reductions in oedema. The range of the strongest correlations with the changes in R2 occurred at echogenicity values of 48-144 (Pearson's correlation coefficient: r = -0.63 and p < 0.01). Thus, it was possible to evaluate the interstitial fluid using echogenicity.

CONCLUSION

The outcome indicators for the evaluation of interstitial fluid using ultrasonography were echogenicities in the range of 48-144, and these values were valid for assessing the interstitial fluid in the subcutaneous tissue.

Factors Associated with Reported Infection and Lymphedema Symptoms among Individuals with Extremity Lymphedema

PURPOSE

This study aimed to examine factors associated with reported infection and symptoms among individuals with extremity lymphedema.

DESIGN

A cross-sectional study was used.

METHODS

Data were collected from a survey supported by the National Lymphedema Network from March 2006 through January 2010. A total of 1837 participants reported having extremity lymphedema. Logistic regression analyses were used.

FINDINGS

Factors associated with reported infection among individuals with extremity lymphedema included male gender, decreased annual household income, decreased self-care, self-report of heaviness, and lower extremity as opposed to upper extremity. Factors associated with symptoms included infection, decreased self-care, lower knowledge level of self-care, decreased annual household income, and presence of secondary lower extremity lymphedema.

CONCLUSIONS/CLINICAL RELEVANCE

Select factors of income, self-care status, and site of lymphedema were associated with increased occurrence of infection and symptoms among individuals with extremity lymphedema. Longitudinal studies are needed to identify risk factors contributing to infections and symptoms in individuals with lymphedema.

Factors predicting adherence to risk management behaviors of women at increased risk for developing lymphedema

PURPOSE

Lymphedema affects 20-30% of women following breast cancer treatment. However, even when women are informed, they do not necessarily adhere to recommended lymphedema self-management regimens. Utilizing the Cognitive-Social Health Information Processing framework, we assessed the cognitive and emotional factors influencing adherence to lymphedema risk management.

METHODS

Women with breast cancer who had undergone breast and lymph node surgery were recruited through the Fox Chase Cancer Center breast clinic. Participants (N = 103) completed measures of lymphedema-related perceived risk, beliefs and expectancies, distress, self-regulatory ability to manage distress, knowledge, and adherence to risk management behaviors. They then received the American Cancer Society publication "Lymphedema: What Every Woman with Breast Cancer Should Know." Cognitive and affective variables were reassessed at 6 and 12 months post-baseline.

RESULTS

Maximum likelihood multilevel model analyses indicated that overall adherence increased over time, with significant differences between baseline and 6- and 12-month assessments. Adherence to wearing gloves was significantly lower than that for all other behaviors except electric razor use. Distress significantly decreased, and knowledge significantly increased, over time. Greater knowledge, higher self-efficacy to enact behaviors, lower distress, and higher self-regulatory ability to manage distress were associated with increased adherence.

CONCLUSIONS

Women who understand lymphedema risk management and feel confident in managing this risk are more likely to adhere to recommended strategies. These factors should be rigorously assessed as part of routine care to ensure that women have the self-efficacy to seek treatment and the self-regulatory skills to manage distress, which may undermine attempts to seek medical assistance.

Chronic oedema/lymphoedema: under-recognised and under-treated

Even though it is estimated that at least 300 000 people in Canada may be affected by chronic oedema/lymphoedema, recognition of the seriousness of this chronic disease in health care is scarce. Lymphoedema affects up to 70% of breast and prostate cancer patients, substantially increasing their postoperative medical costs. Adding to this problem are the escalating rates of morbid obesity across North America and the fact that 80% of these individuals are thought to suffer with an element of lymphoedema. The costs related to these patient populations and their consumption of health care resources are alarming. Untreated chronic oedema/lymphoedema is progressive and leads to infection, disfigurement, disability and in some cases even death. Thus, prognosis for the patient is far worse and treatment is more costly when the disease is not identified and treated in the earlier stages. Although the number of individuals coping with chronic oedema/lymphoedema continues to increase, the disparity between diagnosis, treatment and funding across Canada endures. The reasons for this include a lack of public awareness of the condition, insufficient education and knowledge among health care providers regarding aetiology and management and limited financial coverage to support appropriate methods and materials.
