Personalizing Conservative Lymphedema Management Using Indocyanine Green-Guided Manual Lymphatic Drainage

Comparison of fluid and body composition measures in women with lipoedema, lymphoedema, and control participants

Lipoedema is the disproportionate accumulation of adipose tissue in the lower body, often associated with hormonal changes in women. Lipoedema is commonly misdiagnosed as lymphoedema or obesity due to similarities in appearance. The aim of this study is to compare body composition and fluid measures of women with lipoedema, lymphoedema, and matched control participants, to determine differences that may help distinguish between each condition. One hundred and eleven participants aged over 18, who presented with the complaint of leg swelling and underwent indocyanine green lymphography were included in this study. Our analysis showed that the individuals with lymphoedema had a significantly higher overall total body water (lymphoedema: 9.6 ± 4.2 L, lipoedema: 7.4 ± 2.3 L, control: 7.5 ± 1.8 L; p < .001) and extracellular fluid (lymphoedema: 4.6 ± 1.6, lipoedema: 3.4 ± 1.0 L, control: 3.5 ± 0.7 L; p < .001) in the legs when compared to individuals with lipoedema and matched control participants. Individuals with lipoedema had a significantly higher overall fat mass as a percentage of body weight when compared to individuals with lymphoedema (lymphoedema: 33.1% ± 9.5%, lipoedema: 39.4% ± 6.5%; p = .003). We are unable to distinguish between individuals with lipoedema and control participants, therefore further research needs to be conducted to help reduce misdiagnosis.

Comparing the Impact of Diluents and Injection Techniques on Patient Comfort During Indocyanine Green Lymphangiography: A Prospective Study

Background: Indocyanine green (ICG) lymphography, a key diagnostic tool for lymphedema, is influenced by the dilution process of ICG dye, impacting patient experience. Methods and Results: In our study, we assessed three different ICG diluents-water for injection (WFI), normal saline (NS), and Dextrose® plus human albumin-in five healthy volunteer individuals undergoing superficial lymphography of the upper limb over 3 weeks. Results indicated that NS, as a diluent for ICG, caused the least discomfort during injection, in contrast to WFI, which led to the highest levels of discomfort. Transport time of ICG from the injection site to the axillary lymph nodes was notably shorter in intradermal injections than in subdermal injections. Conclusion: Our findings advocate for using NS as the optimal and cost-effective diluent for ICG, enhancing patient experience.

Advances in lymphedema: An under-recognized disease with a hopeful future for patients

Lymphedema has traditionally been underappreciated by the healthcare community. Understanding of the underlying pathophysiology and treatments beyond compression have been limited until recently. Increased investigation has demonstrated the key role of inflammation and resultant fibrosis and adipose deposition leading to the clinical sequelae and associated reduction in quality of life with lymphedema. New imaging techniques including magnetic resonance imaging (MRI), indocyanine green lymphography, and high-frequency ultrasound offer improved resolution and understanding of lymphatic anatomy and flow. Nonsurgical therapy with compression, exercise, and weight loss remains the mainstay of therapy, but growing surgical options show promise. Physiologic procedures (lymphovenous anastomosis and vascularized lymph node transfers) improve lymphatic flow in the diseased limb and may reduce edema and the burden of compression. Debulking, primarily with liposuction to remove the adipose deposition that has accumulated, results in a dramatic decrease in limb girth in appropriately selected patients. Though early, there are also exciting developments of potential therapeutic targets tackling the underlying drivers of the disease. Multidisciplinary teams have developed to offer the full breadth of evaluation and current management, but the development of a greater understanding and availability of therapies is needed to ensure patients with lymphedema have greater opportunity for optimal care.

The Prevalence of the Axillo-Inguinal Lymphatic Pathway in Lymphedema of the Extremities and Potential Therapeutic Implications

Background: The axillo-inguinal (or inguino-axillary) is a compensatory lymphatic drainage pathway regularly utilized by lymphedema therapists when applying manual lymphatic drainage (MLD) for upper and lower extremity lymphedema. However, there is limited evidence of the frequency of this pathway and the characteristics of patients with lymphedema in which this pathway is present. Indocyanine green (ICG) lymphography is an imaging technique that has the capability to identify lymphatic drainage pathways in lymphedema when combined with MLD. In this study, we used ICG lymphography in patients with upper and lower extremity lymphedema to investigate the presence of this pathway and its clinical characteristics. Methods and Results: A retrospective cohort audit of 563 patients with lymphedema (285 with upper extremity and 278 with lower extremity) who underwent ICG lymphography was conducted in combination with MLD. Compensatory lymphatic drainage was investigated. Patients demonstrating the axillo-inguinal pathway were identified, and their clinical characteristics were recorded. The axillo-inguinal pathway was not demonstrated in any patient with upper extremity and only five patients with lower extremity lymphedema. Of these five patients, all were female with a history of secondary cancer-related lymphedema following gynecological cancer. The majority (four) had bilateral lymphedema extending to the lower abdomen and presented with a greater severity of lymphedema. Conclusions: These findings suggest that the axillo-inguinal pathway is an infrequent compensatory drainage pathway in lower extremity lymphedema and rare in upper extremity lymphedema. Our findings have clinical implications for lymphedema management, in particular, the sequence in which MLD is applied.

Etiology and treatment of cancer-related secondary lymphedema

Lymphedema and specifically cancer-related lymphedema is not the main focus for both patients and physicians dealing with cancer. Its etiology is an unfortunate complication of cancer treatment. Although lymphedema treatments have gained an appreciable consensus, many practitioners have developed and prefer their own specific protocols and this is especially true for conventional (manual) versus surgical treatments. This collection of presentations explores the incidence and genetics of cancer-related lymphedema, early detection and monitoring techniques, both conventional and operative treatment options, and the importance and role of exercise for patients with cancer-related lymphedema. These assembled presentations provide valuable insights into the challenges and opportunities presented by cancer-related lymphedema including the latest research, treatments, and exercises available to improve patient outcomes and quality of life.

Early Detection of Breast Cancer-Related Lymphedema: Accuracy of Indocyanine Green Lymphography Compared with Bioimpedance Spectroscopy and Subclinical Lymphedema Symptoms

Introduction: The reported incidences of breast cancer-related lymphedema (LE) affecting the arms vary greatly. Reason for this variability includes different diagnostic techniques used across studies. In the current study, we compared the accuracy of indocyanine green lymphography (ICG_L) and bioimpedance spectroscopy (BIS) in detecting LE before presentation of clinical signs. Methods and Results: Patients with no initial detectable signs of clinical LE of their arms after axillary lymph node dissection or removal of >5 lymph nodes on sentinel lymph node biopsy were included. Subclinical LE was defined as BIS values outside the normal range [(≥7 units (or >10 units)] or a 7-unit (or 10 unit) change between two measurements. We tracked ICG_L and BIS measurements for 133 potentially affected arms (n = 123). ICG_L detected signs of lymphatic flow disruption in 63 arms (47%). Based on the BIS value of 7 units, 60 arms (45%) had values outside the normal range. When using ICG_L-identified LE cases as true positives, BIS had a 54% accuracy (area under the curve [AUC] = 0.54) in detecting LE. Accuracy was 61% for subclinical LE symptoms when compared with ICG_L (AUC = 0.62). Both BIS and subclinical LE symptoms had <0.70 AUC-receiver characteristic operator curve, suggesting that BIS and development of subclinical LE symptoms are not adequate for identifying patients with subclinical LE. Conclusion: ICG_L is a reliable diagnostic tool for detecting early signs of lymphatic flow disruption in subclinical LE. Utilizing ICG_L to diagnose subclinical LE followed by a personalized treatment plan may provide patients the best chance of preventing disease progression.

Advances in the prevention and treatment of breast cancer-related lymphedema

PURPOSE

Breast cancer-related lymphedema (BCRL) represents a lifelong risk for breast cancer survivors and once acquired becomes a lifelong burden. This review summarizes current BCRL prevention and treatment strategies.

FINDINGS

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

CONCLUSION

Progress in prevention and treatment of BCRL continues, requiring advances in early diagnosis, patient education, expert consensus and novel treatments designed for lymphatic rehabilitation following insults.

Differentiation of lipoedema from bilateral lower limb lymphoedema by imaging assessment of indocyanine green lymphography

Lipoedema is characterized by disproportionate painful fat accumulation mostly in the lower limbs. The presence of lymphoedema in lipoedema remains controversial. This study aimed to assess the presence or absence of lymphoedema in the lower limbs of women with lipoedema using indocyanine green (ICG) lymphography. A cross-sectional retrospective study was undertaken in women with a clinical diagnosis of lipoedema whose lower limbs were examined with ICG lymphography. MD Anderson Cancer Center (MDACC) ICG staging was used to determine lymphoedema presence and severity. Patient characteristics, ICG lymphography findings, Stemmer sign, body mass index, waist-to-hip ratio, limb volume and bioimpedance spectroscopy measures were recorded. Forty women with lipoedema underwent ICG lymphography for the lower limbs from January 2018 to July 2022. Thirty-four women (85.0%) were determined by ICG lymphography as MDACC ICG Stage 0 representing normal lymphatics. Of the six women who demonstrated dermal backflow on ICG lymphography, all were determined as ICG Stage 1, four had localized traumatic dermal backflow area at their ankles, one had previously diagnosed with primary lymphoedema and one was classified as lipoedema stage 4. ICG lymphography findings suggested the absence of lymphoedema in a clear majority of women with lower limb lipoedema.

Gluteal lymphoedema associated with lower extremity lymphoedema: A preliminary study with indocyanine green lymphography and magnetic resonance imaging

INTRODUCTION

Indocyanine green (ICG) lymphography studies have identified that one in three to five patients with cancer-related lower extremity lymphoedema (LEL) demonstrated dermal backflow extending to the gluteal region. This study aimed to further characterize gluteal lymphoedema using contemporaneous magnetic resonance imaging (MRI).

PATIENTS AND METHODS

Twenty-eight patients with unilateral advanced LEL who underwent both ICG lymphography and MRI prior to any surgical procedure were included in this study. The patients were divided into two groups with/without gluteal lymphoedema by the presence of dermal backflow on ICG lymphography. MRI was used to evaluate tissue changes.

RESULTS

Ten patients demonstrated gluteal lymphoedema on ICG lymphography and had a higher incidence of skin hypertrophy in the gluteal region. However, no difference in excess leg volume was found between the two groups. A trend of increasing gluteal subcutaneous tissue in the affected side was identified in patients with gluteal lymphoedema with a median increase of 20% compared with an 11% increase in the non-gluteal lymphoedema group. The excess gluteal subcutaneous tissue was positively correlated to ipsilateral excess leg volume.

CONCLUSION

The gluteal lymphoedema group on ICG lymphography had skin thickening in the gluteal region and was likely identified in the secondary cancer-related group. Surgical and conservative management options for gluteal lymphoedema need to be considered in advanced LEL.

What do we know about treating breast-cancer-related lymphedema? Review of the current knowledge about therapeutic options

Breast-cancer-related lymphedema (BCRL) is a common consequence of oncological treatment. Its management is a complicated, chronic, and arduous process. Therapeutic options can be divided on non-surgical and surgical methods, although there is still no clear consensus about their effectiveness in preventing or stopping the disease. That brings problems in everyday practice, as there are no guidelines about proper time for starting therapy and no agreement about which management will be beneficial for each patient. The aim of this review is to summarize current knowledge about possible treatment choices, non-surgical so as surgical, indicate knowledge gaps, and try to direct pathways for future studies.

Navigating the application of new innovations: Establishing an indocyanine green lymphography clinic in Australia

Translation of evidence into practice in healthcare is challenging, particularly with new innovations. Indocyanine Green (ICG) lymphography is a novel innovation where the superficial lymphatics are imaged to provide information about lymphoedema diagnosis and to guide individualised therapy for a person's long-term chronic management of lymphoedema, supporting care across the continuum to the community setting. Despite the unique information ICG lymphography provides, the technology itself is complex and highly specialised and currently has limited adoption in clinical practice. This paper sought to determine the barriers and enablers to establishing an ICG lymphography clinic within an outpatient lymphoedema service by exploring staff perceptions and experiences. An interpretive descriptive design was used with semi-structured interviews of key staff participants from a quaternary public hospital six months after ICG lymphography clinic establishment. An interview guide was developed, underpinned by the Consolidated Framework for Implementation Research (CFIR), to guide the inquiry. Interview data were transcribed, inductively coded and analysed to identify themes. All eligible management, clinical and ancillary staff were included (N = 8). Four key themes were identified from the data as essential to implementation success. These were support is critical for implementation; beliefs about the technology; practicalities are achievable; and sustainability for ongoing success. Themes were found to be interrelated and centred around support from staff and the organisation as a critical process facilitator. The study demonstrated an ICG lymphography clinic can be successfully established as part of an outpatient lymphoedema service. Key enablers related to positive staff attitudes and beliefs about ICG lymphography and its application. Future implementation sites may consider that although the complexity of this innovation creates process challenges, the use of an implementation framework can assist in identifying determinants of success for effective implementation to practice.

A new indocyanine green fluorescence lymphography protocol for diagnostic assessment of lower limb lymphoedema

INTRODUCTION

The lower limbs are a common body site affected by chronic edema. Imaging examination of the lymphatic system is useful to diagnose lymphoedema, identify structural changes in individuals, and guide interventional strategies. In this study, we used a protocol combining indocyanine green (ICG) lymphography and ICG-guided manual lymphatic drainage (MLD) for the diagnostic assessment of lower limb lymphoedema.

MATERIALS AND METHODS

Patients with lower limb lymphoedema were divided into three groups by their medical history: primary, secondary cancer-related, or secondary non-cancer-related. ICG lymphography was conducted in three phases: initial observation, MLD to accelerate ICG dye transit and reduce imaging time, and imaging data collection. Lymphatic drainage regions were recorded, and the MD Anderson Cancer Center ICG staging was applied. We collected routine lymphoedema assessment data, including limb volume and bioimpedance spectroscopy measurements.

RESULTS

Three hundred and twenty-six lower limbs that underwent ICG lymphography were analyzed. Eight drainage regions were identified. The ipsilateral inguinal and popliteal were recognized as the original regions, and the remaining six regions were considered compensatory regions that occur only in lymphoedema. More than half of the secondary cancer-related lower limb lymphoedema (57.6%) continued to drain to the ipsilateral inguinal region. The incidence of drainage to the ipsilateral inguinal region was even higher for the primary (82.8%) and secondary non-cancer-related (87.1%) groups. Significant associations were observed between cancer-related lymphoedema and the presence of compensatory drainage regions.

CONCLUSIONS

We proposed a prospective ICG lymphography protocol for the diagnostic assessment of lower limb lymphoedema in combination with MLD. Eight drainage regions were identified, including two original and six compensatory regions.

Retrograde Lymph Flow in the Lymphatic Vessels in Limb Lymphedema

OBJECTIVE

Retrograde movement of lymph due to damaged and/or incompetent valves in the lymphatic vessels has been considered a pathological feature of lymphedema. This study aimed to determine the prevalence of retrograde lymph flow and the characteristics of patients with this condition using indocyanine green (ICG) lymphography.

METHODS

An audit of 679 patients with upper or lower limb swelling who underwent ICG lymphography was undertaken over a 4-year period. Harvey's technique was applied to identify retrograde flow in the lymph collecting vessel during ICG lymphography. The characteristics of patients with retrograde lymph flow were recorded.

RESULTS

Twenty-one patients (3.7%, lower limb: n=19, upper limb: n=2) were identified as having retrograde flow in lymph collecting vessels out of 566 confirmed lymphedema patients (lower limb: n=275, upper limb: n=291). Of the two patients with upper limb lymphedema, one had a short segment of retrograde lymph flow in the forearm. The other patient with upper limb lymphedema and one patient with lower limb lymphedema were previously diagnosed with Lymphedema-Distichiasis Syndrome. Of the remaining 18 patients with lower limb lymphedema and retrograde lymph flow, nine had initiating insect bites with lymphangitis and three had palpable benign enlarged inguinal lymph nodes evident prior to lower limb swelling onset. None had cancer-related lower limb lymphedema.

CONCLUSIONS

Retrograde lymph flow with valve incompetence in the lymph collecting vessels was a rare finding in upper limb lymphedema and a relatively uncommon in lower limb lymphedema, contradicting conventional understanding of pathological changes in lymphedema. ICG lymphography identified anticipated retrograde lymph flow in two patients with Lymphedema-Distichiasis. In the remaining patients, retrograde lymph flow may have resulted from toxic or asymptomatic lymphangitis but no association with secondary cancer-related lymphedema. These findings have implication for conservative management as well as lymphovenous anastomosis surgery where both ends of a transected lymph collecting vessel would be potential targets for anastomoses.

Indocyanine Green Lymphography for Evaluation of Breast Lymphedema Secondary to Breast Cancer Treatments

BACKGROUND

 Although breast lymphedema (BL) significantly deteriorates quality of life (QOL) of breast cancer survivors, little is known and pathophysiological severity staging system is yet reported. This study aimed to evaluate usefulness of a novel BL severity staging system based on indocyanine green (ICG) lymphography findings.

METHODS

 Breast cancer survivors with breast symptoms who underwent breast ICG lymphography were included. Breast ICG lymphography stage was determined based on visibility of linear pattern and extension of dermal backflow patterns. Prevalence of breast symptoms and lymphedema QOL score (LeQOLiS) was compared according to the stage.

RESULTS

 Thirty-seven patients were included. Breast ICG lymphography stage included stage 0 in 11 (29.7%) cases, stage I in 3 (8.1%) cases, stage II in 11 (29.7%) cases, stage III in 6 (16.2%) cases, stage IV in 4 (10.8%) cases, and stage V in 2 (5.4%) cases. Higher ICG stages were associated with more frequent prevalence of breast swelling (p = 0.020), breast pain (p = 0.238), and breast cellulitis (p = 0.024), and with higher LeQOLiS (p < 0.001).

CONCLUSION

 ICG lymphography allows clear visualization of superficial lymph circulation in the breast. Higher breast ICG lymphography stages are associated with more frequent prevalence of BL-related symptoms and worse QOL.

Lymphatic Microsurgical Preventive Healing Approach (LYMPHA) for Lymphedema Prevention after Axillary Lymph Node Dissection—A Single Institution Experience and Feasibility of Technique

While surgical options exist to treat lymphedema after axillary lymph node dissection (ALND), the lymphatic microsurgical preventive healing approach (LYMPHA) has been introduced as a preventive measure performed during the primary surgery, thus avoiding the morbidity associated with lymphedema. Here, we highlight details of our operative technique and review postoperative outcomes. For our patients, limb measurements and body composition analyses were performed pre- and postoperatively. Intraoperatively, axillary reverse lymphatic mapping was performed with indocyanine green (ICG) and lymphazurin. SPY-PHI imaging was used to visualize the ICG uptake into axillary lymphatics. Cut lymphatics from excised nodes were preserved for lymphaticovenous anastomosis (LVA). At the completion of the microanastomosis, ICG was visualized draining from the lymphatic through the recipient vein. A retrospective review identified nineteen patients who underwent complete or partial mastectomy with ALND and subsequent LYMPHA over 19 months. The number of LVAs performed per patient ranged between 1–4 per axilla. The operating time ranged from 32–95 min. There were no surgical complications, and thus far one patient developed mild lymphedema with an average follow up of 10 months. At the clinic follow up, ICG and SPY angiography were used to confirm intact lymphatic conduits with an uptake of ICG across the axilla. This study supports LYMPHA as a feasible and effective method for lymphedema prevention.

Indocyanine green lymphography as novel tool to assess lymphatics in patients with lipedema

OBJECTIVE

Lipedema is a chronic and progressive disease associated with lymphatic impairment at later stages. The aim of our study was to describe the functional status and anatomy of lower limb superficial lymphatic system using indocyanine green (ICG) lymphography in patients with lipedema.

METHODS

Following ICG injection at the dorsum of the foot, distance (cm) covered by the dye at 10 (T10') and 25 min (T25') was measured and normalized for limb length. If the dye did not reach the groin within 25 min, patients were classified as "drainage-needing" group (DNG). Values of fat and lean distribution assessed by dual-energy X-ray absorptiometry were extracted, and correlation analysis was performed. Furthermore, anatomical patterns of superficial lymphatics were assessed.

RESULTS

Overall, 45 women were included, 25 (56%) of whom were classified as DNG. Symptoms duration was significantly associated with DNG status at multivariate analysis (odds ratio 1.07; 95% CI 1.01-1.14; p = 0.047). Moreover, Spearman's analysis showed a negative correlation between symptoms duration and T25' dye migration (r = -0.469; p = 0.037). Overall, no major anatomical lymphatic changes were found.

CONCLUSIONS

Present study suggests that lymphatic functioning in patients with lipedema correlates with symptoms duration. Further research on larger cohorts should verify our findings and clarify their potential therapeutic implications. Overall, ICG lymphography may be promising technique to assess both lymphatic anatomy and functioning in patients with lipedema.

Indocyanine green lymphangiography is superior to clinical staging in breast cancer-related lymphedema

Precise staging of breast cancer-related lymphedema (BCRL) is important to guide treatment-decision making. Recent studies have suggested staging of BCRL using indocyanine green lymphangiography (ICG-L) based on the extent of lymphatic injury and dermal backflow patterns. Currently, the benefits of ICG-L compared to conventional clinical staging are unknown. For this study, we included 200 patients with unilateral BCRL. All BCRL patients were staged using ICG-L and clinical exam. The amounts of excess arm volume, fat mass and lean mass were compared between stages using Dual Energy X-Ray Absorptiometry. Multivariate regression models were used to adjust for confounders. For each increase in the patient's ICG-L stage, the excess arm volume, fat mass and lean mass was increased by 8, 12 and 6.5 percentage points respectively (P < 0.001). For each increase in the patient's clinical ISL stage, the volume was increased by 3.5 percentage points (P < 0.05), however no statistically significant difference in the lean and fat mass content of the arm was observed for ascending stages. However, the residual plots showed a high degree of variance for both ICG-L and clinical staging. This study found that ICG-L staging of BCRL was superior to clinical staging in forecasting BCRL excess arm volume, fat mass, and lean mass. However, there was a high degree of variance in excess arm volume, fat mass, and lean mass within each staging system, and neither the ICG-L nor clinical staging forecasted perfectly.

Physical therapies in the decongestive treatment of lymphedema: A randomized, non-inferiority controlled study

OBJECTIVE

To assess whether the treatment with intermittent pneumatic compression plus multilayer bandages is not inferior to classical trimodal therapy with manual lymphatic drainage in the decongestive lymphedema treatment.

STUDY DESIGN

Randomized, non-inferiority, controlled study to compare the efficacy of three physical therapies' regimens in the Decongestive Lymphatic Therapy.

PARTICIPANTS

194 lymphedema patients, stage II-III with excess volume > 10% were stratified within upper and lower limb and then randomized to one of the three treatment groups. Baseline characteristics were comparable between the groups.

INTERVENTION

all patients were prescribed 20 sessions of the following regimens: Group A (control group): manual lymphatic drainage + Intermittent Pneumatic Compression + Bandages; Group B: pneumatic lymphatic drainage + Intermittent Pneumatic Compression + Bandages; and Group C: only Intermittent Pneumatic Compression + Bandages.

END-POINT

Percentage reduction in excess volume (PREV).

RESULTS

All patients improved after treatment. Global mean of PREV was 63.9%, without significant differences between the groups. The lower confidence interval of the mean difference in PREV between group B and group A, and between group C and group A were below 15%, thus meeting the non-inferiority criterion. Most frequent adverse events were discomfort and lymphangitis, without differences between groups. A greater baseline edema, an upper-limb lymphedema and a history of dermatolymphangitis were independent predictive factors of worse response in the multivariate analysis.

CONCLUSIONS

Decongestive lymphatic therapy performed only with intermittent pneumatic compression plus bandages is not inferior to the traditional trimodal therapy with manual lymphatic drainage. This approach did not increase adverse events.

Advances in Lymphedema

Lymphedema is a common, complex, and inexplicably underappreciated human disease. Despite a history of relative neglect by health care providers and by governmental health care agencies, the last decade has seen an explosive growth of insights into, and approaches to, the problem of human lymphedema. The current review highlights the significant advances that have occurred in the investigative and clinical approaches to lymphedema, particularly over the last decade. This review summarizes the progress that has been attained in the realms of genetics, lymphatic imaging, and lymphatic surgery. Newer molecular insights are explored, along with their relationship to future molecular therapeutics. Growing insights into the relationships among lymphedema, obesity, and other comorbidities are important to consider in current and future responses to patients with lymphedema.

Prospective surveillance model in the home for breast cancer-related lymphoedema: a feasibility study

PURPOSE

The aim of this study was to assess the feasibility of delivering a prospective surveillance model in the home over 6 months for women at high risk of developing lymphoedema.

METHODS

A single-group, intervention study recruited 20 women who had surgical and medical treatment for confirmed node-positive invasive breast cancer and therefore at high risk of developing arm lymphoedema. Participants received a package including Bioimpedance Spectroscopy (BIS) monitoring, lymphoedema education and support to promote self-management and physical activity.

RESULTS

Participants adhered to BIS monitoring 74% of the time, and felt extremely confident in using the device. By 6 months, mean BIS L-Dex scores had increased from 3.5 (SD 5.6) to 8.4 (SD 11.1); five women (25%) who experienced >  + 6.5 increase in L-Dex score were fitted with a compression garment. Self-reported symptoms and distress decreased by 0.4 out of 10 (95% CI 0.1 to 0.7); number of self-management strategies used increased by 0.6 (95% CI 0.1 to 1.2); and planned exercise increased by 2.8 h/week (95% CI 0.4 to 5.2).

CONCLUSIONS

These findings indicate a prospective surveillance model of care in the home with BIS is feasible and associated with increased self-management. A Phase II randomised trial is warranted as well as research exploring the costs associated with implementing this model of care for high-risk individuals.
