The N-LVA Study: effectiveness and cost-effectiveness of lymphaticovenous anastomosis (LVA) for patients with cancer who suffer from chronic peripheral lymphoedema - study protocol of a multicentre, randomised sham-controlled trial.

INTRODUCTION: Cancer-related lymphoedema is one of the most debilitating side-effects of cancer treatment with an overall incidence of 15.5%. Patients may suffer from a variety of symptoms, possibly resulting in a diminished health-related quality of life (HRQoL). A microsurgical technique known as lymphaticovenous anastomosis (LVA) might be a promising treatment option. The objective of this study is to evaluate whether LVA is effective and cost-effective compared with sham surgery in improving the HRQoL. METHODS AND ANALYSIS: A multicentre, double-blind, randomised sham-controlled trial conducted in three university hospitals in the Netherlands. The study population comprises 110 patients over the age of 18 years with unilateral, peripheral cancer-related lymphoedema, including 70 patients with upper limb lymphoedema and 40 patients with lower limb lymphoedema. A total of 55 patients will undergo the LVA operation, while the remaining 55 will undergo sham surgery. The follow-up will be at least 24 months. Patients are encouraged to complete the follow-up by explaining the importance of the study. Furthermore, patients may benefit from regular monitoring moments for their lymphoedema. The primary outcome is the HRQoL. The secondary outcomes are the limb circumference, excess limb volume, changes in conservative therapy, postoperative complications, patency of the LVA and incremental cost-effectiveness. ETHICS AND DISSEMINATION: The study was approved by the Medical Ethical Committee of Maastricht University Medical Center on 20 September 2023 (NL84169.068.23). The results will be presented at scientific conferences and published in peer-reviewed medical journals. TRIAL REGISTRATION NUMBER: NCT06082349.

Development of a head and neck lymphoedema specific quality of life tool: The Comprehensive Assessment of Lymphoedema Impact in the Head and Neck.

PURPOSE: To develop a head and neck lymphoedema (HNL) specific quality of life (QoL) instrument to assess physical, functional, and social/emotional impacts of HNL. METHODS: Instrument candidate items were reviewed by patients with HNL and clinicians and rated for importance, clarity, and invasiveness. The Content Validity Ratio was applied for item reduction. Three-step cognitive interviews were conducted with HNL patients to validate the items, survey format, and instructions. RESULTS: Initially, 130 candidate questions were developed. Following item reduction, 52 items progressed to three-step cognitive interviews. Following cognitive interviews, the Comprehensive Assessment of Lymphoedema Impact in Head and Neck (CALI-HaN) included 33 items; 1 global, 10 physical, 7 functional, and 15 emotional. CONCLUSIONS: Physical, functional, and socioemotional effects need to be considered when measuring QoL in patients with HNL. This study describes initial development of the CALI-HaN, an instrument that shows promise for clinical and research applications following future validation.

Lymphedema self-assessment among endometrial cancer survivors.

PURPOSE: Lower extremity lymphedema (LEL), which causes ankle, leg, and feet swelling, poses a significant challenge for endometrial cancer survivors, impacting physical functioning and psychological well-being. Inconsistent LEL diagnostic methods result in wide-ranging LEL incidence estimates. METHODS: We calculated the cumulative incidence of LEL based on survivor-reported Gynecologic Cancer Lymphedema Questionnaire (GCLQ) responses in addition to survivor- and nurse-reported leg circumference measurements among a pilot sample of 50 endometrial cancer survivors (27 White, 23 Black) enrolled in the ongoing population-based Carolina Endometrial Cancer Study. RESULTS: Self-leg circumference measurements were perceived to be difficult and were completed by only 17 survivors. Diagnostic accuracy testing measures (sensitivity, specificity, positive and negative predictive value) compared the standard nurse-measured ≥ 10% difference in leg circumference measurements to GCLQ responses. At a mean of ~11 months post-diagnosis, 54% of survivors met established criteria for LEL based on ≥ 4 GCLQ cutpoint while 24% had LEL based on nurse-measurement. Percent agreement, sensitivity, and specificity approximated 60% at a threshold of ≥ 5 GCLQ symptoms. However, Cohen's kappa, a measure of reliability that corrects for agreement by chance, was highest at ≥ 4 GCLQ symptoms (κ = 0.27). CONCLUSION: Our findings emphasize the need for high quality measurements of LEL that are feasible for epidemiologic study designs among endometrial cancer survivors. Future studies should use patient-reported survey measures to assess lymphedema burden and quality of life outcomes among endometrial cancer survivors.

Surgical lymphedema models in the mice hindlimb-A systematic review and quality assessment.

BACKGROUND: Lymphedema constitutes a major unsolved problem in plastic surgery. To identify novel lymphedema treatments, preclinical studies are vital. The surgical mouse lymphedema model is popular and cost-effective; nonetheless, a synthesis and overview of the literature with evidence-based guidelines is needed. The aim of this review was to perform a systematic review to establish best practice and support future high-quality animal studies exploring lymphedema treatments. METHODS: We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, searching four databases (PubMed, Embase, Web of Science, and Scopus) from inception-September 2022. The Animals in Research Reporting In Vivo Experiments 2.0 (ARRIVE 2.0) guidelines were used to evaluate reporting quality. Studies claiming to surgically induce lymphedema in the hindlimb of mice were included. RESULTS: Thirty-seven studies were included. Four main models were used. (1) Irradiation+surgery. (2) A variation of the surgery used by (1) + irradiation. (3) Surgery only (SPDF-model). (4) Surgery only (PLND-model). Remaining studies used other techniques. The most common measurement modality was the caliper. Mean quality coefficient was 0.57. Eighteen studies (49%) successfully induced sustained lymphedema. Combination of methods seemed to yield the best results, with an overrepresentation of irradiation, the removal of two lymph nodes, and the disruption of both the deep and superficial lymph vessels in the 18 studies. CONCLUSION: Surgical mouse hindlimb lymphedema models are challenged by two related problems: (1) retaining lymphedema for an extended period, that is, establishing a (chronic) lymphedema model (2) distinguishing lymphedema from post-operative edema. Most studies failed to induce lymphedema and used error-prone measurements. We provide an overview of studies claiming to induce lymphedema and advocate improved research via five evidence-based recommendations to use: (1) a proven lymphedema model; (2) sufficient follow-up time, (3) validated measurement methods; (4) ARRIVE-guidelines; (5) contralateral hindlimb as control.

The added value of SPECT/CT lymphoscintigraphy in the initial assessment of secondary extremity lymphedema patients.

An added value of SPECT/CT over planar lymphoscintigraphy for initial staging in patients with secondary extremity lymphedema was investigated. Furthermore, we developed a hybrid SPECT/CT classification combining dermal backflow (DBF) of SPECT and honeycomb pattern (HP) of CT, correlated it with lymphoscintigraphic staging and clinical severity. Forty-one patients with secondary extremity lymphedema who underwent lymphoscintigraphy with SPECT/CT were included retrospectively. The severity of extremity lymphedema was assessed using CT volumetry. Lymphoscintigraphic findings were evaluated using the Taiwan Lymphoscintigraphy Staging (TLS), and CT-based and SPECT-based quantitative analysis were performed. TLS was performed by planar scintigraphy only and with SPECT/CT, respectively. The SPECT/CT findings were classified into DBF-/HP-, DBF+/HP-, DBF+/HP+, and DBF-/HP+. Based on these findings, patients were categorized into five classes: Class 1 = DBF-HP- entire limb, Class 2 = DBF+/HP- proximal/distal limb without DBF+/HP+ or DBF-/HP+, Class 3 = DBF+/HP+ proximal/distal limb without DBF-/HP+, Class 4 = Mixed DBF+/HP+ and DBF-/HP+ in proximal/distal limb, Class 5 = DBF-/HP+ entire limb. Adding SPECT/CT to planar scintigraphy showed a 15.4% modification rate in lymphoscintigraphic staging. HP volume ratio significantly increased as clinical severity and lymphoscintigraphic staging increased, while DBF volume ratio increased with severity and followed expected patterns according to lymphoscintigraphic staging. Hybrid SPECT/CT lymphoscintigraphic classification showed strong positive correlation with clinical severity and TLS. Our results demonstrated substantial modification of lymphoscintigraphic staging by adding SPECT/CT to a conventional planar scintigraphy. In addition, a hybrid SPECT/CT is expected to provide new indicators reflecting lymphoscintigraphic staging and clinical severity by providing both of functional DBF and anatomical HP information.

Assessment of proprioception, muscle strength and endurance during dynamic isokinetic test in patients with breast cancer-related lymphedema.

BACKGROUND: Breast cancer-related lymphedema is a common complication after breast cancer treatment.This study examined isokinetic proprioception, muscular strength, and endurance by comparing extremity with lymphedema and the extremity without lymphedema in women with breast cancer-related lymphedema. METHODS: A total of 15 individuals aged between 35 and 70 years participated in this study. Cybex Humac NORM Isokinetic dynamometer (CSMi, Stoughton, MA) were used to assess upper extremity passive proprioception, active proprioception, kinesthesia, muscle strength, and muscle endurance. The upper extremity lymphedema was measured with the water displacement arm volumetry test using a volumeter. FINDINGS: All isokinetic measurements demonstrated a statistically significant difference between the extremity with lymphedema and the extremity without lymphedema, suggesting lower scores in the extremity with lymphedema (p < .05). There was a positive correlation between passive internal rotation in the extremity with lymphedema and the time after mastectomy (r= 0.628, p = .012) and a moderate positive relationship was found between the time after lymphedema and passive internal rotation (r = 0.577; p = .024), and active external rotation position sense (r = 0.540; p = .038) in the extremity with lymphedema. Also, a unidirectional positive moderate (r = 0.594; p = .020) relationship was found between the lymphedema stage and passive external rotation in the extremity with lymphedema. INTERPRETATION: The difference in proprioception, muscle strength, and endurance between the extremity with lymphedema and the extremity without lymphedema in women with breast cancer-related lymphedema will provide valuable information in terms of prioritizing these parameters in treatment.

Assessment and management of upper limb lymphoedema in advanced disease: a case study.

Lymphoedema is thought to affect around 200 000 people in the UK (NHS England, 2023). Secondary lymphoedema is a relatively common complication of cancer and cancer treatment, and in advanced disease it may present a challenging issue for community nursing staff caring for patients approaching the end of their lives. In this article, a case study considers the assessment and treatment of upper limb lymphoedema in a patient with advanced metastatic breast cancer. Management of this complex and distressing condition requires holistic assessment and collaborative care planning with the patient and their wider care team, including onward referral to specialist lymphoedema and palliative care services. The case study considers the typical presentation of lymphoedema in an upper limb, exclusion of reversible causes for oedema, awareness of palliative care emergencies such as superior vena cava obstruction, and the provision of supportive therapeutic interventions in context of the patient's expressed wishes for her ongoing care.

Managing the Morbidity: Individualizing Risk Assessment, Diagnosis, and Treatment Options for Upper Extremity Lymphedema.

In the setting where breast cancer-related lymphedema (BCRL) remains a feared and common complication of breast cancer, here we review important factors for the development, diagnosis, prevention, and treatment of BCRL. We find that race/ethnicity affect BCRL development risk, that future studies should focus on understanding the biological reasons behind the increased susceptibility of certain racial minorities to BCRL, that surveillance, early detection, exercise programs, and arm compression can reduce the risk of BCRL, and that surgical techniques to preserve and restore lymphatic drainage being evaluated in randomized trials may become transformative in reducing BCRL risk for high-risk patients.

Effect of illness perception on predicting breast cancer-related lymphedema risk management behaviours among breast cancer patients: A comparison between dimensions and profiles.

AIM: This study aimed to explore the utility of latent profile analysis of illness perception, in comparison to treating illness perception as several dimensions, to predict breast cancer-related lymphedema risk management behaviours among Chinese breast cancer patients. METHODS: This is a 3-month longitudinal study. From August 2019 to January 2021, patients who recently underwent breast cancer surgery including axillary lymphadenectomy were recruited. Illness perception and risk management behaviours were measured by breast cancer-related lymphedema specific questionnaires before discharge following surgery (n = 268) and at 3 months postsurgery (n = 213), respectively. RESULTS: Treating illness perception as several dimensions, 'illness coherence' and 'timeline (cyclical)' dimensions were found to be significantly associated with breast cancer-related lymphedema risk management behaviours. Using the latent profile analysis, two illness perception profiles were identified and significant differences were revealed in breast cancer-related lymphedema risk management behaviours between them. Overall, illness perception profiles explained smaller amounts of variability in breast cancer-related lymphedema risk management behaviours than illness perception dimensions. CONCLUSION: Future studies could combine these two different perspectives of illness perception regarding breast cancer-related lymphedema into the design of interventions to improve breast cancer-related lymphedema risk management behaviours.

Risk-of-bias assessment of the randomized clinical trials and systematic reviews on surgical treatments for breast cancer-related lymphedema: A mapping review.

BACKGROUND: Breast cancer treatment is the principal cause of lymphedema in the upper extremities. Breast cancer-related lymphedema (BCRL) treatments were previously based on conservative therapy; surgical treatments are alternative options that could be highly beneficial, especially for patients who are not responsive to conservative therapy. The main aim of this study was to describe and critically assess the risk of bias of randomized clinical trials (RCTs) and systematic reviews (SRs) on surgical treatment for BCRL. METHODS: We conducted an evidence mapping review according to the methodology proposed by Global Evidence Mapping (GEM). An update was done for our previous systematic search in MEDLINE, EMBASE, CENTRAL (Cochrane), and Epistemonikos from the year 2000 onward. We assessed the risk of bias for the RCTs and SRs using the RoB-2 and ROBIS tools, respectively. RESULTS: Two surgical RCTs and eight SRs were found among the 47 surgical studies that met the eligibility criteria. The overall risk-of-bias assessments of these studies were rated as some concerns (six outcomes) and high risk (three outcomes) for the measured outcomes among the RCTs and as a high risk of bias (five studies) and low risk (three studies) for the included SRs. CONCLUSIONS: The overall evidence in the literature on surgical treatment for BCRL is low, as there are few published RCTs and SRs, and the risk-of-bias assessment for the majority was rated as high risk of bias or with some concerns. High-quality studies are needed to improve evidence-based decision-making by surgeons and patients.

Financial toxicity experienced by patients with breast cancer-related lymphedema: a systematic review.

PURPOSE: To perform a systematic review on financial toxicity of breast cancer-related lymphedema. METHODS: Seven databases were searched on September 11, 2022. Eligible studies were identified, analyzed, and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Empirical studies were appraised by the Joanna Briggs Institute (JBI) tools. The Mixed Methods Appraisal Tool version 2018 was used to assess the mixed method studies. RESULTS: A total of 963 articles were identified, but only 7 articles reporting on 6 studies met the eligibility criteria. A 2-year treatment for lymphedema was approximately USD$14,877 to USD$23,167 in America. In Australia, the average out-of-pocket costs ranged from A$207 to A$1400 (USD$156.26 to USD$1056.83) per year. Outpatient visits, compressed clothing, and hospital admissions were the dominant costs. The financial toxicity was associated with the severity of lymphedema, and patients with heavy financial burden had to reduce other expenses or even forgo the treatment. CONCLUSION: Breast cancer-related lymphedema aggravated the economic burden of patients. The included studies showed great variation in the methods used and therefore differences in cost results. The national government should further improve the healthcare system and increase the insurance coverage of lymphedema treatment to alleviate this burden. More research is needed to focus on financial toxicity experience of breast cancer patients with lymphedema. IMPLICATIONS FOR CANCER SURVIVORS: The cost of the ongoing treatment of breast cancer-related lymphedema influences patients' economic situation and quality of life. Survivors need to be informed early about the potential financial burden associated with lymphedema treatment.

Prospective, early longitudinal assessment of lymphedema-related quality of life among patients with locally advanced breast cancer: The foundation for building a patient-centered screening program.

BACKGROUND: We examined how breast cancer-related lymphedema (BCRL) affects health-related quality of life (HRQOL), productivity, and compliance with therapeutic interventions to guide structuring BCRL screening programs. METHODS: We prospectively followed consecutive breast cancer patients who underwent axillary lymph node dissection (ALND) with arm volume screening and measures assessing patient-reported health-related quality of life (HRQOL) and perceptions of BCRL care. Comparisons by BCRL status were made with Mann-Whitney U, Chi-square, Fisher's exact, or t tests. Trends over time from ALND were assessed with linear mixed-effects models. RESULTS: With a median follow-up of 8 months in 247 patients, 46% self-reported ever having BCRL, a proportion that increased over time. About 73% reported fear of BCRL, which was stable over time. Further in time from ALND, patients were more likely to report that BCRL screening reduced fear. Patient-reported BCRL was associated with higher soft tissue sensation intensity, biobehavioral, and resource concerns, absenteeism, and work/activity impairment. Objectively measured BCRL had fewer associations with outcomes. Most patients reported performing prevention exercises, but compliance decreased over time; patient-reported BCRL was not associated with exercise frequency. Fear of BCRL was positively associated with performing prevention exercises and using compressive garments. CONCLUSIONS: Both incidence and fear of BCRL were high after ALND for breast cancer. Fear was associated with improved therapeutic compliance, but compliance decreased over time. Patient-reported BCRL was more strongly associated with worse HRQOL and productivity than was objective BCRL. Screening programs must support patients' psychological needs and aim to sustain long-term compliance with recommended interventions.

The effect of combined risk factors on breast cancer-related lymphedema: a study using decision trees.

BACKGROUND: The effect of combined risk factors on breast cancer-related lymphedema (BCRL) development has not yet been investigated. This study aimed to determine the combination of risk factors associated with BCRL development in patients who underwent breast cancer resection, including axillary lymph node dissection (ALND). METHODS: The participants included 129 women who were diagnosed with early-stage breast cancer and underwent breast cancer resection in this retrospective observational study. We performed a decision tree analysis to detect the combination of risk factors associated with BCRL development using age, body mass index (BMI), surgical side, mastectomy, the extent of ALND, and adjuvant therapy (chemotherapy, hormone therapy, and radiation therapy). RESULTS: Of the 129 participants, 11 (8.5%) developed BCRL. Postoperative chemotherapy was the optimal variable selected to classify patients who developed BCRL and those who did not. In participants with postoperative chemotherapy, the extent of ALND was selected as the second layer of the decision tree. When ALND was at level 3, BMI was selected as the third layer. We found that BCRL incidence was 44.4% in individuals with a BMI of 23.0 or higher. CONCLUSIONS: The combination of postoperative chemotherapy, level 3 ALND, and BMI of 23.0 or higher may further increase the risk of developing BCRL. The decision tree model will enable the identification of patients with a high risk of developing BCRL, and thus, preventive intervention, careful monitoring, and early treatment will be possible.

Under recognition and treatment of lymphedema in head and neck cancer survivors - a database study.

PURPOSE: Head and neck cancer (HNC) will be diagnosed in approximately 54,000 Americans in 2022 with more than 11,000 dying as a result. The treatment of HNC often involves aggressive multimodal therapy including surgery, radiotherapy, and systemic therapy. HNC and its treatments are associated with multiple painful and function-limiting neuromusculoskeletal and visceral long-term and late effects. Among these is head and neck lymphedema (HNL), the abnormal accumulation of protein rich fluid, in as many as 90% of survivors. Though HNL is common and potentially contributory to other function-limiting issues in this population, it is notoriously understudied, underrecognized, underdiagnosed, and undertreated. This study seeks to determine the incidence of HNC-related lymphedema diagnosis and treatment in a large US healthcare claims repository database. METHODS: A retrospective observational cohort design and data from an integrated US healthcare claims repository-the IBM MarketScan Commercial Claims and Encounters (CCAE) and Medicare Supplemental and Coordination of Benefits (MDCR) Databases spanning the period April 1, 2012 through March 31, 2020. RESULTS: Of the 16,654 HNC patients eligible for evaluation, 1,082 (6.5%) with a diagnosis of lymphedema were identified based on eligibility criteria. Of the 521 HNC patients evaluated for lymphedema treatment, 417 (80.0%) patients received 1.5 courses of MLD, 71 (13.6%) patients were prescribed compression garments, and 45 (8.6%) patients received an advanced pneumatic compression device. CONCLUSION: HNL in this population of HNC survivors was underdiagnosed and treated compared with contemporary assessments HNL incidence.

Bioimpedance spectroscopy for breast cancer-related lymphedema assessment: clinical practice guidelines.

PURPOSE: Breast cancer-related lymphedema (BCRL) represents a significant concern for patients following breast cancer treatment, and assessment for BCRL represents a key component of survivorship efforts. Growing data has demonstrated the benefits of early detection and treatment of BCRL. Traditional diagnostic modalities are less able to detect reversible subclinical BCRL while newer techniques such as bioimpedance spectroscopy (BIS) have shown the ability to detect subclinical BCRL, allowing for early intervention and low rates of chronic BCRL with level I evidence. We present updated clinical practice guidelines for BIS utilization to assess for BCRL. METHODS AND RESULTS: Review of the literature identified a randomized controlled trial and other published data which form the basis for the recommendations made. The final results of the PREVENT trial, with 3-year follow-up, demonstrated an absolute reduction of 11.3% and relative reduction of 59% in chronic BCRL (through utilization of compression garment therapy) with BIS as compared to tape measurement. This is in keeping with real-world data demonstrating the effectiveness of BIS in a prospective surveillance model. For optimal outcomes patients should receive an initial pre-treatment measurement and subsequently be followed at a minimum quarterly for first 3 years then biannually for years 4-5, then annually as appropriate, consistent with previous guidelines; the target for intervention has been changed from a change in L-Dex of 10 to 6.5. The lack of pre-operative measure does not preclude inclusion in the prospective surveillance model of care. CONCLUSION: The updated clinical practice guidelines present a standardized approach for a prospective model of care using BIS for BCRL assessment and supported by evidence from a randomized controlled trial as well as real-world data.

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.

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.

Systematic review of head and neck lymphedema assessment.

Head and neck lymphedema (HNL) is an increasingly recognized complication of head and neck cancer and its treatment. However, no consensus exists on the "gold-standard" assessment tool for the purposes of diagnosis, classification, or monitoring of HNL. We conducted a systematic review of the literature regarding HNL assessment to determine the optimal method/s of assessment for patients with HNL. A review of publications between January 2000 and September 2021 was undertaken on four electronic databases. Studies were excluded if no clear assessment method of HNL was documented. Sixty-seven articles were included in the study. A wide range of assessment methods for HNL have been reported in the literature. For the purposes of diagnosis and classification of physical findings, computed tomography (CT) appears the most promising tool available for both external and internal HNL. In terms of monitoring, ultrasound appears optimal for external HNL, while a clinician-reported rating scale on laryngoscopy is the gold standard for internal HNL. Patient-reported assessment must be considered alongside objective methods to classify symptom burden and monitor improvement with treatment.

Prevalence and management of filarial lymphoedema and its associated factors in Lindi district, Tanzania: A community-based cross-sectional study.

OBJECTIVE: To determine the burden and management of filarial lymphoedema and its associated factors in Lindi district, Tanzania. METHODS: Cross-sectional study involving 954 community members who were screened for filarial lymphoedema by using a checklist. Moreover, lymphoedema patients were examined for the presence of entry lesions, staging of disease, and interviewed on acute dermatolymphangioadenitis (ADLA) attacks, and their current practices on lymphoedema management. Descriptive statistics and logistic regression analyses were performed. A p < 0.05 was considered statistically significant. RESULTS: The prevalence of filarial lymphoedema was 7.8%, with the majority in the early stage of lymphoedema (78.4%). The large majority (98.6%) of the patients had lower limb lymphoedema and 46% of lymphoedema patients had entry lesions. More than a half (60.8%) of those lymphoedema patients had experienced ADLA attacks; close to two-thirds (64.8%) had one or two attacks in the past 6 months. Generally, patients had inappropriate hygiene care practices for filarial lymphoedema management. Inappropriate hygiene care practice for lymphoedema management was associated with an increased risk for the development of advance stage of lymphoedema (adjusted odds ratio = 7.379, 95%, confidence interval: 3.535-16.018, p = 0.04). CONCLUSION: Though lymphatic filariasis transmission has drastically declined, chronic manifestations of lymphoedema persist in Lindi district. The recommended disease management practices are deficient, which calls for a programmatic approach for mapping the burden of lymphoedema and implementing its management.

Impact of lymphadenectomy and lymphoedema on health-related quality of life 1 year after surgery for endometrial cancer. A prospective longitudinal multicentre study.

OBJECTIVE: To assess the impact of lymphadenectomy and lymphoedema of the lower limbs (LLL) on health-related quality of life (HRQoL) 1 year after surgery for endometrial cancer (EC). DESIGN: Prospective longitudinal cohort multicentre study. SETTING: Departments of obstetrics and gynaecology at four university hospitals, six central hospitals and four county hospitals in Sweden. POPULATION: Two-hundred-and-thirty-five women with early stage EC were included; 116 with high-risk EC underwent surgery including lymphadenectomy (+LA), and 119 with low-risk EC had surgery without lymphadenectomy (-LA). METHODS: The generic SF-36 and EQ-5D-3L and the lymphoedema-specific LYMQOL questionnaire were used to assess HRQoL. LLL was assessed by systematic circumferential measurements of the legs enabling volume estimation, clinical evaluation and patient-reported perception of leg swelling. All assessments were carried out on four occasions; preoperatively, and 4-6 weeks, 6 months and 1 year postoperatively. MAIN OUTCOME MEASURE: HRQoL scores. RESULTS: No significant differences were seen in HRQoL between the +LA and -LA groups 1 year postoperatively. Irrespective of method of determining LLL, women with LLL were significantly more affected in the LYMQOL domains Function, Appearance/body image and Physical symptoms, but not in the domain Emotion/mood, than women without LLL. No such differences were seen in the generic HRQoL or in the LYMQOL global score between the groups with and without LLL. CONCLUSIONS: Lymphadenectomy did not seem to affect generic HRQoL adversely. Irrespective of the method of measuring, LLL affected the lymphoedema-specific HRQoL negatively, mainly in physical domains, but had no impact on the generic HRQoL. TWEETABLE ABSTRACT: Lymphoedema has impact on lymphoedema-specific, but not on generic, HRQoL, 1 year after surgery for EC.
