RESUMO

BACKGROUND: Poor access to lymphoedema specialists and communication between them and patients prevents appropriate lymphoedema management. Therefore, development and dissemination of remote systems is necessary to improve care in rural areas with limited medical personnel or access to medical coordination. AIMS: The authors evaluated the elements required for providing patient education on conservative therapy for lymphoedema, to determine the feasibility of remote management. METHODS: The study involved connecting a health professional in a local clinic (point A) treating a patient with lymphoedema, who was present alongside the clinician, with a specialist certified lymphoedema therapist (CLT) located remotely in a university (point B). FINDINGS: The CLT was able to greet, interview and provide guidance to the patient on conservative therapy. Direct contact with the patient was not possible, which limited visualisation, palpation, leg circumference measurement, and lymphatic drainage management. CONCLUSION: The findings suggest that remote a lymphoedema management approach involving conservative therapy benefits both patients and health professionals, particularly in rural regions. Future studies are needed to confirm the effectiveness of this approach to confirm adequate treatment.

RESUMO

Lymphedema is known to affect as many as 140 to 250 million people worldwide. Approximately 99% of lymphedemas are secondary cases after lymphadenectomy, radiation, or parasite infection. There has been no accurate estimate of the lymphedema population size in South Korea. This study aimed to quantify the epidemiology of lymphedema in South Korea and analyze the clinical characteristics of patients with lymphedema using a nationwide database. This large-scale cross-sectional study included patients who received one of the following three diagnostic codes - Q82.0 (hereditary lymphedema), I97.2 (breast cancer-related lymphedema), and I89.0 (unclassified lymphedema) from the Korean Health Insurance Review and Assessment service between January 2019 and July 2022 at tertiary hospitals, general hospitals, or other hospitals. The demographics of the lymphedema population, medication use, and medical characteristics were identified. Over the last 4 years, the annual incidence of lymphedema has steadily increased and peaked in 2021 with the number 1.85 out of 1000. Of all patients, 81% were located in the upper extremity, and 10.6% had previous cancer. Most patients were diagnosed in general hospitals (53.2%), at orthopedic surgery department (41.9%). On average, lymphedema patients spent 70.17 US dollar for medication and hospitalized for 16.9 days annually after diagnosis. Commonly prescribed medications were Entelon® (Vitis vinifera seed extract) (66.9%), steroids (40.5%), non-steroidal anti-inflammatory drugs (26.5%) and diuretics (21.8%). Only 5.7% of patients received surgery and 19.2% received herbal medicine. This is the first study in South Korea to quantify demographic and medical characteristics of lymphedema patients. These results will contribute to a comprehensive understanding of lymphedema diagnosis and treatment in our nation.

RESUMO

OBJECTIVES: To evaluate the efficacy of acupuncture in treating breast cancer-related lymphedema (BCRL) by using systematic review and Meta analysis method. METHODS: Searching CNKI, Wanfang Data Knowledge Service Platform, VIP Chinese Journal Service Platform, Chinese Biomedical Literature Database, PubMed, Cochrane Library, Embase and Web of Science, the randomized controlled trials (RCTs) literature of acupuncture for BCRL was collected from the establishment of the databases to October 1st, 2023. After data extraction and risk of bias evaluation of the included literature, Meta-analysis was performed using RevMan5.4 software. RESULTS: A total of 14 RCTs with 952 patients were included. The Meta-analysis results showed that compared with comprehensive decongestive therapy (CDT), CDT-associated methods and other interventions of the contro group, acupuncture was able to decrease the circumference of the proximal 10 cm to elbow crease (MD=-1.95, P=0.000 5), reduce the difference in arm circumference (MD=-1.30, P<0.000 01), and increase the effective index (MD=27.47, P<0.000 01;RR=1.23, P=0.000 5);acupuncture improves the range of motion(ROM) scores of shoulder joint in four areas:anteflexion(SMD=0.47, P=0.04), posterior extension (SMD=0.87, P<0.000 01), abduction (SMD=0.48, P=0.03), and adduction (SMD=0.72, P=0.000 5);acupuncture also could alleviate pain and improve visual analog scale (VAS) scores (MD=-1.15, P<0.000 01). No serious adverse reactions were reported in the literatures. CONCLUSIONS: Acupuncture can effectively improve the degree of limb edema and subjective symptoms in BCRL patients.

RESUMO

PURPOSE: Breast cancer-related lymphedema (BCRL) impairs upper limb function and cognitive performance. This study aimed to evaluate the effects of fifteen sessions of complex decongestive therapy (CDT) on fine motor performance and information processing speed in women with BCRL. METHODS: Thirty-eight women with BCRL (54.97 ± 10.78 years) were recruited in the study. Participants either received five times weekly CDT consisting of manual lymphatic drainage, skin care, compression bandaging, and remedial exercises (n = 19) or served as a wait-list control group (n = 19). We used the Finger Tapping Task to assess fine motor performance and the Digit Symbol Substitution Test to assess information processing speed. ANCOVA was performed to analyze the effect of CDT on the dependent variables, adjusting for covariates and baseline values. RESULTS: CDT significantly improved finger tapping score (p < 0.001) compared to the wait-list to the control group, whereas information processing speed did not significantly change (p = 0.673). CONCLUSION: The findings suggest that CDT is an effective conservative therapeutic approach to improve upper extremity fine motor function in women with BCRL. Future studies are needed to investigate the effect of CDT on different cognitive domains.

RESUMO

PURPOSE: This study investigated the accuracy of activity trackers in chronic lower limb lymphoedema (LLL) patients and in comparison to matched controls. MATERIALS AND METHODS: Seventeen LLL patients and 35 healthy subjects wore an activity tracker at the hip (Fitbit Zip/Inspire; hip-AT) and one at the wrist (Fitbit Alta/Inspire; wrist-AT) combined with a reference activity monitor (Dynaport Movemonitor; DAM), for 14 consecutive days. To analyze accuracy and agreement, mean daily step count from both AT's were compared to DAM. To evaluate the accuracy as coaching tool, day-by-day differences were calculated. The Kendall correlation coefficient was used to test consistency of ranking daily steps between the AT's and the DAM. RESULTS: The wrist-AT significantly overestimated daily step count compared to DAM in the LLL group (+1221 ± 1754 steps per day, p = 0.011) while the hip-AT underestimated the step count, although not significantly. Similar results were found in the healthy control group. As a coaching tool, both wrist-AT and hip-AT showed a moderate correlation with the DAM (r = 0.507 and 0.622, respectively) in the LLL group regarding consistency of ranking from most to least active days. CONCLUSION: Wrist-AT's significantly overestimate daily step count in a LLL population. As a coaching tool, both trackers show moderate validity, indicating applicability to improve physical activity.

RESUMO

Lower extremity lymphedema (LEL) is a common complication following surgical staging of endometrial cancer. LEL is a chronic condition associated with significant impact on patient morbidity and quality of life (QoL). This review aimed to report the current evidence in the literature on secondary LEL after surgical staging for endometrial cancer, focusing on the incidence based on different approaches to lymph node staging, diagnosis, risk factors, and the impact on QoL. Due to the absence of a standardized agreement regarding the methodology for evaluating LEL, the documented frequency of occurrence fluctuates across different studies, ranging from 0% to 50%. Systematic pelvic lymphadenectomy appears to be the primary determinant associated with the emergence of LEL, whereas the implementation of sentinel lymph node biopsy has notably diminished the occurrence of this lymphatic complication after endometrial cancer staging. LEL is strongly associated with decreased QoL, lower limb function, and negative body image, and has a detrimental impact on cancer-related distress reported by survivors. Standardization of lymphedema assessment is needed, along with cross-cultural adaptation of subjective outcome measures for self-reported LEL. The advent of sentinel lymph node mapping represents the ideal approach for accurate nodal assessment with less short- and long-term morbidity. Further research is needed to definitively assess the prevalence and risk factors of LEL and to identify strategies to improve limb function and QoL in cancer survivors with this chronic condition.

RESUMO

AIM: This study aimed to investigate the effect of the presence of metabolic syndrome (MetS) on the limb volume and quality of life (QoL) of patients who underwent complex decongestive therapy (CDT) due to unilateral breast cancer-related lymphedema (BCRL). METHODS: Forty female patients with unilateral BCRL, of whom 20 had MetS (MetS group) and 20 did not have MetS (control group), were included in the study. The participants received CDT 5 days a week for 3 weeks. The participants' limb volume (percentage of excess volume (PEV) and percentage reduction of excess volume (PREV) was determined using a tape measure, and their QoL was assessed using the Lymphedema Quality of Life questionnaire (LYMQoL) before and after treatment. RESULTS: After the treatment, the PEV and PREV values and LYMQoL-symptoms scores of the patients improved (p < 0.05); however, the LYMQoL-function, appearance/body image, mood/emotions, and overall QoL scores did not change in the MetS group (p > 0.05). In the control group, the PEV and PREV values and the LYMQoL-appearance/body image, mood/emotions, and overall QoL scores improved (p < 0.05), but the LYMQoL-symptoms and LYMQoL-function scores did not change (p > 0.05). There was a greater increase in the post-treatment PEV and PREV values of the control group compared to the MetS group (p < 0.001). CONCLUSION: The study yielded that CDT was an effective treatment in BCRL with and without MetS; however, the improvement was greater in BCRL cases without MetS than in those with MetS. Therefore, the presence of MetS should be taken into account in the treatment of lymphedema in patients who develop BCRL. TRIAL REGISTRATION: ClinicalTrials.gov, identifier: NCT05426993.

RESUMO

OBJECTIVE: To evaluate the foot-health-related quality of life in individuals with versus without lower-limb lymphedema. METHODS: A case-control study was carried out in an academic clinic in Lisbon, Portugal. Eighty participants (40 controls and 40 with lymphedema) were included in the study. The researchers examined sociodemographic and clinical data and foot-health-related quality of life in both groups. In the group with lymphedema, lower-limb lymphedema was also characterized. RESULTS: Individuals with lower-limb lymphedema had significantly lower scores on all dimensions of the Foot Health Status Questionnaire in comparison with the control group. CONCLUSIONS: Individuals with lower-limb lymphedema appear to have a poorer foot-health-related quality of life than the general population.

RESUMO

OBJECTIVE: The aim of this study is to cross-culturally adapt the Lymphoedema Functioning, Disability and Health Questionnaire Lymphoedema (LYMPH-ICF) instrument into Brazilian Portuguese and conduct a pilot application (n = 10), without psychometric pretensions. METHOD: Methodological research was conducted, following the steps of translation, synthesis, back-translation, and evaluation by the expert committee. Two translators, two back-translators, and twelve professionals participated in the expert committee. A pretest was carried out with 10 patients with secondary lymphedema due to breast cancer. The degree of agreement was determined by the content validity coefficient. RESULTS: It was necessary to modify 8 out of the 29 questions comprising the questionnaire, which exhibited idiomatic disagreement. However, despite these changes, there were no indications of impairments, as content reliability was achieved through a validity coefficient of 0.90. FINAL CONSIDERATIONS: The instrument was successfully translated and cross-culturally adapted for Brazil with a high level of agreement.

RESUMO

OBJECTIVE: This study aimed to investigate the effects of complex decongestive therapy (CDT) applied to the lower extremities of patients with lymphedema of different causes on the extremity volume, quality of life (QoL), and functionality. MATERIALS AND METHOD: The study included 90 patients, of whom 28 had primary lymphedema, 30 had secondary lymphedema, 18 had phlebolymphedema, and 14 had lipolymphedema. A total of 137 extremities were treated with CDT. The patients who received CDT for 5 days a week for 3 weeks (15 sessions in total) were included in the sample. Extremity volume was measured using a tape measure. The lymphedema QoL-Leg Questionnaire was used to evaluate QoL, and the lower extremity functional scale (LEFS) was administered to assess lower extremity functionality. RESULTS: The changes in QoL before and after treatment significantly differed in the primary lymphedema, phlebolymphedema, and lipolymphedema groups (p < 0.05). The post-treatment LEFS scores indicated a significant decrease in the phlebolymphedema and lipolymphedema groups compared to the pre-treatment scores (p < 0.05). CONCLUSIONS: The difference in appearance, which is one of the sub-parameters of QoL, significantly decreased in the comparisons performed between the groups, whereas the changes in the remaining parameters were not significant.

RESUMO

BACKGROUND: Breast cancer-related lymphedema (BRCL) is a potential sequela of high-risk breast cancer treatment. Preventive treatment with immediate lymphatic reconstruction (ILR) at the time of axillary lymph node dissection (ALND) has emerged as the standard of care; however, there is relatively little known about factors that may contribute to procedural failure. METHODS: A retrospectively maintained, institutional review board-approved study followed patients who underwent ILR at the time of ALND at our tertiary care center between May 2018 and May 2023. Patients who presented for at least one follow-up visit in our multidisciplinary lymphedema clinic met the criteria for inclusion. Patients who developed lymphedema despite ILR and potential contributing factors were further explored. RESULTS: 349 patients underwent ILR at our institution between May 2018 and May 2023. 341 of these patients have presented for follow-up in our multidisciplinary lymphedema clinic. 32 (9.4%) patients developed lymphedema despite ILR. This cohort was significantly more likely to be obese (56% vs 35%, P = 0.04). Multivariate logistic regression demonstrates increased odds of procedural failure in patients with a body mass index (BMI) ≥30 kg/m2 (odds ratio 2.6 [1.2-5.5], P = 0.01). CONCLUSION: These data comment upon our institutions outcomes following ILR. Patients who develop lymphedema despite ILR tend to have a higher BMI, with a significantly increased risk in patients with a BMI of 30 or greater. Consideration of these data is critical for preprocedural counseling and may support a BMI cutoff when considering candidacy for ILR going forward, as well as when optimizing failures for secondary lymphedema procedures.

RESUMO

Lymphatic disorders presenting in the first year of life are difficult to identify and manage given the broad range of underlying etiologies. Neonatal lymphatic disease arising from congenital or acquired conditions results in the abnormal accumulation of lymph fluid in the pleura (chylothorax), peritoneum (chylous ascites) and skin (edema/anasarca). There is also increasing recognition of lymphatic losses through the intestine resulting in protein-losing enteropathy (PLE). While the incidence of lymphatic disorders in neonates is unclear, advances in genetic testing and lymphatic imaging are improving our understanding of the underlying pathophysiology. Despite these advancements, medical management of neonatal lymphatic disorders remains challenging and variable among clinicians.

RESUMO

Secondary lymphedema is a chronic and incurable disease lacking satisfactory therapeutic drugs. It primarily results from lymphatic vessel dysfunction resulting from factors such as tumor-related surgery, injury, or infection. Promoting lymphangiogenesis and lymphatic vessel remodeling is crucial for restoring tissue fluid drainage and treating secondary lymphedema. In this study, we discovered that the oral administration of a type-II arabinogalactan (CAPW-1, molecular weight: 64 kDa) significantly promoted lymphangiogenesis and alleviated edema in mice with secondary lymphedema. Notably, the tail diameter of the CAPW-1200 group considerably decreased in comparison to that of the lymphedema group, with an average diameter difference reaching 0.98 mm on day 14. CAPW-1 treatment also reduced the average thickness of the subcutaneous area in the CAPW-1200 group to 0.37 mm (compared with 0.73 mm in the lymphedema group). It also facilitated the return of injected indocyanine green (ICG) from the tail tip to the sciatic lymph nodes, indicating that CAPW-1 promoted lymphatic vessel remodeling at the injury site. In addition, CAPW-1 enhanced the proliferation and migration of lymphatic endothelial cells. This phenomenon was associated with the activation of the toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) signaling pathway, thereby promoting the expression of vascular endothelial growth factor-C (VEGF-C), which can be abolished using a TLR4 antagonist. Despite these findings, CAPW-1 did not alleviate the symptoms of lymphedema or restore lymphatic drainage in VEGFR3flox/flox/Prox1-CreERT2 mice. In summary, CAPW-1 alleviates secondary lymphedema by promoting lymphangiogenesis and lymphatic vessel remodeling through the activation of the TLR4/NF-κB/VEGF-C signaling pathway, indicating its potential as a therapeutic lymphangiogenesis agent for patients with secondary lymphedema.

RESUMO

Lipedema and lymphedema are physically similar yet distinct diseases that are commonly misdiagnosed. We previously reported that lipedema and lymphedema are associated with increased risk for venous thromboembolism (VTE). The underlying etiology of the prothrombotic profile observed in lipedema and lymphedema is unclear, but may be related to alterations in platelets. Our objective was to analyze the platelet transcriptome to identify biological pathways that may provide insight into platelet activation and thrombosis. The platelet transcriptome was evaluated in patients with lymphedema and lipedema, then compared to control subjects with obesity. Patients with lipedema were found to have a divergent transcriptome from patients with lymphedema. The platelet transcriptome and impacted biological pathways in lipedema were surprisingly similar to weight-matched comparators, yet different when compared to overweight individuals with a lower body mass index (BMI). Differences in the platelet transcriptome for patients with lipedema and lymphedema were found in biological pathways required for protein synthesis and degradation, as well as metabolism. Key differences in the platelet transcriptome for patients with lipedema compared to BMI-matched subjects involved metabolism and glycosaminoglycan processing. These inherent differences in the platelet transcriptome warrant further investigation, and may contribute to the increased risk of thrombosis in patients with lipedema and lymphedema.

RESUMO

The aim of this study was to describe the clinical and molecular genetic findings in seven individuals from three unrelated families with Blau syndrome. A complex ophthalmic and general health examination including diagnostic imaging was performed. The NOD2 mutational hot spot located in exon 4 was Sanger sequenced in all three probands. Two individuals also underwent autoinflammatory disorder gene panel screening, and in one subject, exome sequencing was performed. Blau syndrome presenting as uveitis, skin rush or arthritis was diagnosed in four cases from three families. In two individuals from one family, only camptodactyly was noted, while another member had camptodactyly in combination with non-active uveitis and angioid streaks. One proband developed two attacks of meningoencephalitis attributed to presumed neurosarcoidosis, which is a rare finding in Blau syndrome. The probands from families 1 and 2 carried pathogenic variants in NOD2 (NM_022162.3): c.1001G>A p.(Arg334Gln) and c.1000C>T p.(Arg334Trp), respectively. In family 3, two variants of unknown significance in a heterozygous state were found: c.1412G>T p.(Arg471Leu) in NOD2 and c.928C>T p.(Arg310*) in NLRC4 (NM_001199139.1). In conclusion, Blau syndrome is a phenotypically highly variable, and there is a need to raise awareness about all clinical manifestations, including neurosarcoidosis. Variants of unknown significance pose a significant challenge regarding their contribution to etiopathogenesis of autoinflammatory diseases.

RESUMO

Lymphedema is an intractable disease with few effective therapeutic options. Autologous mesenchymal stem cell (MSC) transplantation is a promising therapy for this disease. However, its use is limited by the cost and time for preparation. Recently, xenotransplantation of porcine MSCs has emerged as an alternative to autologous MSC transplantation. In this study, we aimed to clarify the usefulness of neonatal porcine bone marrow-derived MSC (NpBM-MSC) xenotransplantation for the treatment of lymphedema. One million NpBM-MSCs were xenotransplanted into the hind limbs of mice with severe lymphedema (MSC transplantation group). The therapeutic effects were assessed by measuring the femoral circumference, the volume of the hind limb, the number and diameter of lymphatic vessels in the hind limb, and lymphatic flow using a near-infrared fluorescence (NIRF) imaging system. We compared the effects using mice with lymphedema that did not undergo NpBM-MSC transplantation (negative control group). The condition of the transplanted NpBM-MSCs was also evaluated histologically. The femoral circumference and volume of the hind limb had been normalized by postoperative day (POD) 14 in the MSC transplantation group, but not in the negative control group (P = 0.041). NIRF imaging revealed that lymphatic flow had recovered in the MSC transplantation group by POD 14, as shown by an increase in luminance in the hind limb. Histological assessment also showed that the xenotransplantation of NpBM-MSC increased the proliferation of lymphatic vessels, but they had been rejected by POD 14. The xenotransplantation of NpBM-MSCs is an effective treatment for lymphedema, and this is mediated through the promotion of lymphangiogenesis.

RESUMO

Introduction: We presented the key findings from Singapore's Changi General Hospital Breast Centre's lymphedema surveillance strategy that used patients' reported symptoms, standard arm circumference measurements and clinical assessment in the diagnosis of breast cancer-related lymphedema (BCRL). Our secondary aim was to highlight and discuss important elements of a surveillance strategy that can be implemented to track this outcome measure of breast cancer treatment for future research. Method: We conducted a cross-sectional study of 511 breast cancer patients to assess the prevalence of BCRL and its associated risk factors. We defined BCRL prevalence rates based on patients' self-reporting, objective arm circumference measure-ments and clinical diagnosis based on International Society of Lymphology (ISL) staging. Results: The median follow-up of patients was 88.8 months. The cumulative prevalence rate in the cohort was 30.9%. The cohort of BCRL patients were older (58.4 versus [vs] 54.9 years), had higher mean Body Mass Index (27.7 vs 25.2), higher proportion of mastectomy (77% vs 64.3%), axillary clearance, less likely breast reconstruction, higher-grade tumour, more lymph nodes excised, more advanced nodal disease, and had undergone adjuvant chemotherapy. However, clinically apparent BCRL was only 6.5% (33 out of 511 patients). The proportion of clinically significant BCRL in patients undergoing sentinel lymph node biopsy (SLNB) or axillary sampling was 1.7% compared to 9.9% in patients who had undergone axillary clearance. Majority of the BCRL were subclinical or mild in severity. Conclusion: Our study showed that our rates of BCRL were comparable to international rates and highlighted similar patient profiles who were at risk of developing the disease. Having a comprehensive lymphedema surveillance strategy is paramount in paving the way for future studies.
