Outcomes and bioethical implications of lymphadenectomy in mastectomized patients: Importance and indication of ultrasound-guided fine-needle aspiration biopsy / Resultados e implicaciones bioéticas de la linfadenectomía en pacientes mastectomizadas: Importancia y recomendación de biopsia por aspiración con aguja fina guiada por ecografía / Resultados e implicações bioéticas da linfadenectomia em pacientes mastectomizadas: Importância e recomendação da biópsia aspirativa com agulha fina guiada por ultrassom

Introduction: Lymph node involvement is the main prognostic factor in breast cancer. Mastectomized patients usually undergo lymphadenectomy (LA) of micrometastatic sentinel lymph nodes (SLNs) despite the evidence of AMAROS trial to replace this therapy with radiotherapy in select cases. Objective: Demonstrate the ability of ultrasonography to detect non-metastatic or micrometastatic SLNs. Materials and methods: 132 patients who underwent mastectomy were evaluated. Ultrasound-guided fine-needle aspiration biopsy (FNAB) was indicated for suspicious lymph nodes. LA and SNL biopsy (SLNB) were performed in patients with positive and negative FNAB, respectively. LA was performed in FNAB positive or SLNB positive cases, except in the presence of isolated tumor cells and micrometastatic SLNs. The tumor burden after LA in patients with negative FNAB and positive SLNB was measured; the presence of two or fewer positive SLNs was considered a low burden. Results: Sensitivity of FNAB for detecting positive lymph nodes in patients with a high tumor burden was 93% and specificity was 84%. Positive (PPV) and negative predictive value (NPV) were 60% and 79%, respectively. Conclusions: LA could have been avoided in 90% of mastectomized patients with negative FNAB and a low tumor burden who met the AMAROS criteria with a high NPV (79%).

Introducción: La afectación ganglionar es el principal factor pronóstico en cáncer de seno. Generalmente, pacientes mastectomizadas se somenten a linfadenectomia (LA) de ganglios linfáticos centinela micrometastásicos (GLCs), a pesar de la evidencia del ensayo AMAROS en ciertos casos para reemplazarla con radioterapia. Objetivo: Demostrar la importancia de la ecografía para detectar GLCs no metastásicos o micrometastásicos. Materiales y métodos: Se evaluaron132 pacientes sometidas a mastectomía. Se recomendó biopsia aspirativa con aguja fina (BAAF) por ultrasonido para ganglios linfáticos sospechosos. Se realizó Biopsia LA y biopsia de GLCs (BGLC) en pacientes con BAAF positiva y negativa, respectivamente. En casos positivos de BAAF o BGLC se ejecutó LA, excepto en presencia de células tumorales aisladas y GLCs. Se evaluó la carga tumoral posterior a LA en pacientes con BAAF negativa y BGLC positiva. La presencia de dos o menos GLC positivos se consideró carga baja. Resultados: La sensibilidad de BAAF para detectar nódulos linfáticos positivos en pacientes con alta carga tumoral fue del 93%; la especificidad fue del 79%. Valores predictivos positivo (60%) y negativo (79%). Conclusiones: Se podría haber evitado LA en 90% de pacientes mastectomizadas con BAAF negativa y baja carga tumoral que cumplían criterios AMAROS con alto VPN (79%).

Introdução: O comprometimento dos gânglios é o principal fator prognóstico no câncer de mama. Geralmente, pacientes mastectomizadas são submetidas a linfadenectomia (LA) de gânglios linfáticos sentinelas de micrometástases (GLSs), apesar da evidência do estudo AMAROS em certos casos para substituí-la por radioterapia. Objetivo: Demonstrar a importância da ultrassonografia na detecção de GLSs não metastáticos ou micrometástase. Materiais e métodos: Foram avaliadas 132 pacientes submetidas à mastectomia. A biópsia aspirativa com agulha fina (BAAF) ultrassônica foi recomendada para gânglios linfáticos suspeitos. A biópsia LA e a biópsia do GLSs (BGLS) foram realizadas em pacientes com BAAF positivo e negativo, respectivamente. Nos casos positivos de BAAF ou BGLS, a LA foi realizada, exceto na presença de células tumorais isoladas e GLSs. A carga tumoral após a LA foi avaliada em pacientes com BAAF negativa e BGLS positiva. A presença de dois ou menos GLS positivos foi considerada carga baixa. Resultados: A sensibilidade do BAAF para detectar linfonodos positivos em pacientes com alta carga tumoral foi de 93%; a especificidade foi de 79%. Valores preditivos positivos (60%) e negativos (79%). Conclusões: a LA poderia ter sido evitada em 90% das pacientes mastectomizadas com BAAF negativa e baixa carga tumoral que preencheram os critérios AMAROS com alto VPN (79%).

Transcutaneous Electrical Acupoint Stimulation Combined with Warm Acupuncture for Breast Cancer Related Upper Limb Lymphedema: A Retrospective Cohort Study / 中国结合医学杂志

OBJECTIVE@#To observe the clinical efficacy of transcutaneous electrical acupoint stimulation (TEAS) combined with warm acupuncture in treating breast cancer associated with upper limb lymphedema (BCRL).@*METHODS@#This was a retrospective cohort study using a paired control design. Fifty-two BCRL patients were assigned to the control group (27 cases) and the treatment group (25 cases). The patients in the control group were treated with lymphedema comprehensive detumescence treatment (CDT) for 4 weeks, including systematic therapy composed of manual lymphatic drainage, compression bandage, skincare, and functional exercise. The patients in the treatment group were treated with TEAS combined with warm acupuncture based on the control group methods. Each treatment lasted for 30 min and was applied twice a week for 4 weeks. The arm circumference (AC) of different positions of the affected limb and the degree of swelling of the affected limb were evaluated before the first treatment and after the last treatment. The clinical efficacy was evaluated according to the degree of edema before and after treatment. All adverse events during treatment were recorded.@*RESULTS@#The patients' AC and the swelling feeling of the affected limb in the treatment group and the control group were both reduced compared with those before treatment. Compared with the control group, AC of the wrist joint transverse stria, the midpoint between the wrist joint transverse stria and the elbow joint transverse stria in the treatment group were significantly reduced (P<0.05). The decrease in AC diameter at the midpoint between the elbow joint transverse stria and the axillary transverse stria was the most significant (P<0.01). The swelling degree of the affected limbs in the treatment group was significantly lower than before treatment, and was significantly lower compared with the control group after treatment (P<0.01). The total effective rate was 72% in the treatment group, significantly higher than that in the control group (55.56%, P<0.05). No serious adverse events occured in either group.@*CONCLUSIONS@#TEAS combined with warm acupuncture can effectively reduce AC and swelling feeling of the affected limb in patients with BCRL. The effect is better than that of CDT therapy alone. (Registration No. ChiCTR2200062075).

Advances in treatment of lymphedema with supraclavicular vascularized lymph node transfer / 中国修复重建外科杂志

OBJECTIVE@#To review the research progress of supraclavicular vascularized lymph node transfer (VLNT).@*METHODS@#The research literature related to supraclavicular VLNT at home and abroad in recent years was extensively reviewed, and the anatomy of supraclavicular lymph nodes, clinical applications, and complications of supraclavicular VLNT were summarized.@*RESULTS@#The supraclavicular lymph nodes are anatomically constant, located in the posterior cervical triangle zone, and the blood supply comes mainly from the transverse cervical artery. There are individual differences in the number of supraclavicular lymph nodes, and preoperative ultrasonography is helpful to clarify the number of lymph nodes. Clinical studies have shown that supraclavicular VLNT can relieve limb swelling, reduce the incidence of infection, and improve quality of life in patients with lymphedema. And the effectiveness of supraclavicular VLNT can be improved by combined with lymphovenous anastomosis, resection procedures, and liposuction.@*CONCLUSION@#There are a large number of supraclavicular lymph nodes, with abundant blood supply. It has been proven to be effective for any period of lymphedema, and the combined treatment is more effective. The more clinical studies are needed to clarify the effectiveness of supraclavicular VLNT alone or in combination, as well as the surgical approach and timing of the combined treatment.

Immobilization, Lymphedema, and Obesity are Predictive Factors in the Development of Adhesive Capsulitis in Breast Cancer Patients / Imobilização, linfedema e obesidade são fatores preditivos no desenvolvimento de capsulite adesiva em pacientes com câncer de mama

Abstract Objective Adhesive capsulitis is a condition characterized by shoulder pain and stiffness. Breast cancer treatment has been linked to the development of this condition, but its mechanisms are still little known. This study's objective was to identify predictors factors associated with the development of adhesive capsulitis in breast cancer patients. Methods A case control study was performed with women undergoing treatment for breast cancer in a single center. The sampling was nonprobabilistic and consecutive. Adhesive capsulitis was defined as constant pain associated with decreased active and passive shoulder movement in anterior elevation, external rotation at 0°/90° abduction, and internal rotation at 90° abduction. The study group consisted of patients with shoulder pain and range of motion limitations, while the control group consisted of women without any shoulder abnormalities. Sociodemographic and clinical variables were collected. A univariate logistic regression was used to assess the influence of variables on the studied outcome. For p< 0.20, a multivariate logistic regression was used. The probability of null hypothesis rejection was 5%. Results A total of 145 women were assessed, with 39 (26.9%) on the study group and 106 (73.1%) on the control group. The majority was under 60 years old. In the multivariate analysis, variables correlated to the outcome under study were shoulder immobilization (OR = 3.09; 95% CI: 1.33-7.18; p= 0.009), lymphedema (OR = 5.09; 95% CI: 1.81-14.35; p= 0.002), and obesity (OR = 3.91; 95% CI: 1.27-12.01; p= 0.017). Conclusion Lymphedema, postsurgery immobilization, and obesity are predictive factors for the development of adhesive capsulitis in breast cancer patients.

Resumo Objetivo Capsulite adesiva é uma afecção caracterizada por dor e limitação dos movimentos do ombro. O tratamento do câncer de mama está relacionado ao desenvolvimento dessa doença por meio de mecanismos ainda pouco conhecidos. O objetivo do estudo foi identificar os fatores associados ao desenvolvimento de capsulite adesiva em pacientes com câncer de mama. Métodos Um estudo caso-controle foi realizado com mulheres em tratamento para câncer de mama em um centro único. A amostra foi consecutiva e não-probabilística. A capsulite adesiva foi pré-definida como dor constante e diminuição da amplitude de movimentos em elevação anterior, rotação externa em 0°/90° abdução e rotação interna em 90° abdução. O grupo caso foi constituído por pacientes com dor e limitação de todos os movimentos do ombro, enquanto o controle por pacientes sem qualquer alteração nesta articulação. Variáveis sociodemográficas e clínicas foram coletadas. Foi realizada uma análise de regressão logística univariada para avaliar a influência das variáveis em relação ao desfecho estudado. Para valores de p< 0,20, realizou-se a análise de regressão logística multivariada. A probabilidade de se rejeitar a hipótese nula foi de 5%. Resultados Foram avaliadas 145 mulheres, sendo 39 casos (26,9%) casos e 106 controles (73,1%). Na análise multivariada, as variáveis associadas ao desfecho estudado foram imobilização do ombro (OR = 3,09; 95% IC: 1,33-7,18; p= 0,009), linfedema (OR = 5,09; 95% IC: 1,81-14,35; p= 0,002) e obesidade (OR = 3,91; 95% IC: 1,27-12,01; p= 0,017). Conclusão Linfedema, imobilização pós-cirúrgica e obesidade são fatores preditores associados ao desenvolvimento de capsulite adesiva em pacientes com câncer de mama.

Terapia descongestiva como complemento a la cirugía de anastomosis linfáticovenosas y transferencia de linfonodos vascularizados: Una revisión de la literatura / Decongestive therapy as an adjunct to lymphatic-venous anastomosis surgery and vascularized lymph node transfer: A review of the literature

Resumen Introducción: El linfedema es una enfermedad inflamatoria crónica que afecta cerca de 250 millones de personas en el mundo. El tratamiento tradicional es la terapia descongestiva. Últimamente, existe la opción de complementar el tratamiento tradicional con procedimientos quirúrgicos fisiológicos como anastomosis linfáticovenosas y transferencia de linfonodos vascularizados. Sin embargo, la evidencia del uso de la terapia descongestiva en los cuidados pre y posoperatorios en estas cirugías es limitada. Objetivo: Evaluar el uso de terapia descongestiva como complemento a la cirugía de linfedema mediante anastomosis linfáticovenosas y transferencia de linfonodos vascularizados. Materiales y Método: Se realizó una revisión de la literatura en las siguientes bases de datos: Cochrane, Pubmed y Google académico, utilizando los siguientes términos mesh: "anastomosis, surgical", "lymphedema", "perioperative care", "microsurgery", "rehabilitation", "therapy", "lymph nodes", "bypass", "lymphedema and microsurgery". Se incluyó aquellos artículos que describían el uso de la terapia descongestiva en los cuidados pre- y posoperatorios. Resultados: Se identificó un total de 201 artículos y 12 fueron incluidos en el análisis. La evidencia reporta que las terapias más usadas en el cuidado pre- y posoperatorio son compresión, drenaje linfático manual y tratamientos personalizados. Sin embargo, la mayoría de los autores hace una descripción vaga de las terapias mencionadas. Discusión y Conclusión: La evidencia respecto al uso de terapia descongestiva como tratamiento complementario es débil. Los expertos recomiendan su uso, sin embargo, se necesitan futuras investigaciones que describan el uso de cada uno de sus componentes como complemento de procedimientos quirúrgicos fisiológicos para el manejo del linfedema.

Background: Lymphedema is a disease that affects about 250 million people around the world. The traditional treatment is decongestive therapy. In the past years, there is the option to complementing the traditional treatment with physiological surgical procedures such as lymphatic-venous anastomosis (LVA) and vascularized lymph node transfer (VLNT). However, the evidence for the use of decongestive therapy in pre- and post-operative care in these surgeries is limited. Aim: To evaluate the use of decongestive therapy as a complement to lymphedema surgery such a lymphatic-venous anastomosis and transfer of vascularized lymph nodes. Materials and Method: A literature review was carried out in the following databases: Cochrane, Pubmed and Academic Google, using the following mesh terms: "anastomosis, surgical", "lymphedema", "perioperative care", "microsurgery", "rehabilitation", "therapy", "lymph nodes","bypass", "lymphedema and microsurgery". "Those articles that described the use of decongestive therapy in pre- and post-operative care were included. Results: 201 articles were identified and 12 were included in the analysis. The evidence reports that the most used therapies in pre- and post-operative care are compression, manual lymphatic drainage and personalized treatments. However, most of the authors give a vague description of the mentioned therapies. Discussion and Conclusion: The evidence regarding the use of decongestive therapy as a complementary treatment is weak. Experts recommend its use; however, future research is needed to describe the use of each of its components as a complement to physiological surgical procedures for the management of lymphedema.

Lymphocintilographic evaluation of lymphatic circulation in victims of circuferential degloving injuries of the lower limbs / Avaliação linfocintilográfica da circulação linfática em pacientes vítimas de desenluvamentos circunferenciais dos membros inferiores

ABSTRACT Introduction: secondary forms of lymphedema may occur as consequence of tumors, surgeries, radiotherapy, trauma and infections. Degloving injuries are severe and infrequent forms of trauma, with avulsion at the level of muscular fascia, and consequent injury of the lymphatic system. Objective: to evaluate the alterations in lymphatic circulation in patients being victims of circumferential degloving injuries in the lower limbs, using lymphoscintigraphic. Patients and Methods: retrospective analysis of the cases treated in the period from 2010 to 2016. Segmental, circumferential and unilateral injuries with involvement of the lower limbs were included. Lymphoscintigraphy was performed after a minimum interval of 12 months after the end of treatment. The non-injured lower limb was used as control. The Kleinhans Semiquantitative Index (KSI) was used for the semiquantitative evaluation of the lymphoscintigraphic findings. Results: eighteen patients were evaluated, six of whom were female and 12 were male. The mean age was 28.11 years. The average vertical extension of the circumferential traumatized segment was 29.33cm. The injured area presented variations of 5 to 15% of the body surface, with an average of 8.95%. Lymphoscintigraphy was performed after an average interval of 22.55 months. Alterations were observed on the traumatized limb (TL) in 13 patients. All control limbs (CL) were normal. The mean KSI observed in TL was 8.32, while in CL, the average value was 0.58 (p<0.001). Conclusion: patients with circumferential degloving injuries in the lower limbs present compromised lymphatic circulation and high probability to develop lymphedema.

RESUMO Introdução: as formas secundárias de linfedema podem ocorrer em consequência de tumores, cirurgias, radioterapia, traumas e infecções. Os desenluvamentos são formas graves e infrequentes de trauma, sendo observada avulsão no plano da fáscia muscular, com consequente lesão do sistema linfático. Objetivo: avaliar as alterações na circulação linfática nos pacientes vítimas de desenluvamentos circunferenciais nos membros inferiores, a partir da análise linfocintilográfica. Pacientes e Métodos: análise retrospectiva dos casos atendidos no período de 2010 a 2016. Foram incluídos os casos com acometimento segmentar, circunferencial e unilateral em membros inferiores. A linfocintilografia foi realizada após um intervalo mínimo de 12 meses do término do tratamento. O membro inferior não traumatizado foi utilizado como controle. Para a avaliação semiquantitativa dos achados linfocintilográficos, utilizou-se o Índice de Kleinhans (ISQTK). Resultados: foram avaliados 18 pacientes, sendo seis do gênero feminino e 12 do masculino. A média de idade foi de 28,11 anos. A extensão vertical do segmento traumatizado circunferencial foi em média de 29,33cm. O segmento traumatizado apresentou variações de 5 a 15% da superfície corporal, com média de 8,95%. A linfocintilografia foi realizada após intervalo médio de 22,55 meses. Foram observadas alterações no exame linfocintilográfico do membro traumatizado (MT) em 13 pacientes. Todos os exames dos membros controle (MC) foram normais. O ISQTK médio observado no MT foi 8,32 (0,3-20,75). No MC o valor médio foi de 0,58 (0,15-0,75). Conclusão: os pacientes com desenluvamentos circunferenciais nos membros inferiores apresentam circulação linfática comprometida e alta probabilidade para o desenvolvimento de linfedema.

Síndrome de Stewart-Treves no membro inferior com apresentação exuberante: relato de caso / Profuse Stewart-Treves syndrome in the right leg: a case report

A Síndrome de Stewart-Treves é uma rara condição onde um angiossarcoma se desenvolve sobre área de linfedema crônico. Afeta mais frequentemente os membros superiores e representa 5% dos casos de angiossarcoma. Apesar de ser mais comum em mulheres submetidas a mastectomia radical e esvaziamento axilar por neoplasia de mama, pode ocorrer a partir de linfedema de outras etiologias. Clinicamente as lesões são caracterizadas por nódulos únicos ou múltiplos de cor avermelhada ou azulada no estágio inicial e, em estágio avançado, podem evoluir para massas hemorrágicas e até gangrena. O prognóstico é ruim e a conduta cirúrgica com excisão ampla ou amputação oferecem uma maior chance de sobrevida. Relata-se um caso de Síndrome de Stewart-Treves na perna direita, apresentando-se de forma exuberante e com acometimento de linfonodos pélvicos e abdominais.

Stewart-Treves syndrome is a rare condition characterized by the development of an angiosarcoma at sites of chronic lymphedema. It most often affects the upper limbs and accounts for 5% of cases of angiosarcoma. Although the syndrome is more common in women undergoing radical mastectomy and axillary dissection for breast cancer, it may result from lymphedema of other etiologies. Clinically, the lesions are characterized by single or multiple bluish-red nodules in the early stage and may progress to hemorrhagic masses and even gangrene in advanced stages. The prognosis is poor, and surgical management with wide excision or amputation offers a greater chance of survival. We report a case of profuse Stewart-Treves syndrome in the right leg, with involvement of pelvic and abdominal lymph nodes.

Identification and preservation of arm lymphatics in axillary lymph node dissection to prevent arm lymphedema: a single center randomized controlled trial / 中华肿瘤杂志

Objective: To evaluate the feasibility of identification and preservation of arm lymphatics (DEPART) in axillary lymph node dissection (ALND) for breast cancer to prevent arm lymphedema. Methods: A randomized controlled study method was used. Two hundred and sixty-five patients who underwent breast cancer surgery at the Department of Thyroid and Breast Surgery, Zhongnan Hospital of Wuhan University from November 2017 to June 2018 were included, and the patients were randomly divided into ALND+ DEPART group (132 patients) and standard ALND group (133 patients) by random number table method. In the ALND+ DEPART group, indocyanine green and methylene blue were injected as tracers before surgery, and the arm sentinel nodes was visualized by staged tracing during intraoperative dissection of axillary lymph nodes. Partial frozen sections were made of arm lymph nodes >1 cm in length and hard and suspicious of metastasis, and arm lymph nodes and lymphatic vessels were selectively preserved. Patients in the standard ALND group underwent standard ALND. Objective and subjective indexes of arm lymphedema were evaluated by 5-point circumference measurement and Norman questionnaire. Results: Among 132 breast cancer patients in the ALND+ DEPART group, 121 (91.7%) completed DEPART. There were no statistically significant differences in age, body mass index, pathological type, dissection number of axillary lymph node, N stage, TNM stage, molecular typing, and regional radiotherapy between the ALND+ DEPART and standard ALND groups (P>0.05). At a median follow-up of 24 months, assessment by the 5-point circumference measurement showed that the incidence rates of lymphedema in the ALND+ DEPART and standard ALND groups were 5.0% (6/121) and 15.8% (21/133), respectively, with statistically significant differences (P=0.005). Assessment by the Norman questionnaire showed that the incidence rates of lymphedema in the ALND+ DEPART and standard ALND groups were 5.8% (7/121) and 21.8% (29/133), respectively, with a statistically significant difference (P<0.001). No local regional recurrence was observed in either group during the follow-up period. Conclusion: For breast cancer patients with positive axillary lymph nodes, the administration of DEPART during ALND can reduce or avoid the occurrence of arm lymphedema without compromising oncology safety.

Linfedema: de la fisiopatología al tratamiento actual / Lymphedema: from pathophysiology to current treatment

Resumen El linfedema es la acumulación de líquido rico en proteínas en el intersticio debido a una incompetencia de los canales linfáticos. Se clasifica en primario cuando es ocasionado por anormalidades estructurales congénitas en los canales linfáticos, mientras que el secundario está causado por disrupciones en la integridad anatómica, que pueden acontecer después de trauma, infecciones (filariasis linfática), posterior a vaciamientos ganglionares, o iatrogénica. Objetivo: Describir los aspectos más importantes del tratamiento del linfedema entendiéndose este desde la fisiopatología. Metodología: Se incluyeron artículos publicados en idiomas español e inglés, la mayoría entre 2011 y 2021 que tuvieran contenido relacionado con el objetivo del presente manuscrito. Conclusiones: El linfedema se ha convertido en un reto para los profesionales de la salud debido a su complejo tratamiento multidisciplinario, pero gracias al avance de la microcirugía, el manejo quirúrgico se convertido en una creciente alternativa efectiva, especialmente gracias a su enfoque fisiopatológico de la enfermedad. MÉD. UIS.2021;34(3): 61-70.

Abstract Lymphedema is the accumulation of protein-rich fluid in the interstitium due to an incompetence of the lymphatic channels. It is classified as primary when it occurs due to lymphatic channels abnormalities, and secondary lymphedema when it is caused by trauma, infection, venous thrombosis, oncological diseases and iatrogenia, especially after lymph node dissection. Objective: To describe the most important aspects in the treatment of lymphedema, understanding it from a pathophysiological perspective. Methodology: Articles published in Spanish and English were included, the majority between 2011 and 2021 that have content related to the objective of this manuscript. Conclusions: Lymphedema has become a challenge to physicians due to the complex and multidisciplinary treatment that it requires, but, owing to the advance from microsurgery, the surgical management has become an increasingly effective alternative, especially because of its disease pathophysiological approach.

Linfedema congénito primario bilateral. Reporte de caso / Bilateral primary congenital lymphedema. Case report

RESUMEN Fundamento: El linfedema congénito primario es una condición rara con un componente genético importante que se caracteriza por edema crónico de la zona afectada. Objetivo: Presentar un linfedema congénito primario bilateral y discutir su origen. Presentación de caso: Se presentó un caso de linfedema congénito primario bilateral en un niño de 2 años de edad, sin antecedentes patológicos familiares de la enfermedad. Se discutieron sus posibles causas genéticas ya que existen varias mutaciones que explican su origen. Aunque no se pudieron realizar estudios genéticos para conocer la etiología exacta, existen evidencias clínicas de que no se trata de una enfermedad de Milroy, a menos que se presente como una mutación de novo. Se le realizó al paciente un seguimiento desde su diagnóstico hasta la actualidad. Conclusiones: Existen múltiples mutaciones genéticas que explican el origen de un linfedema congénito primario, por lo que no necesariamente debe tratarse de enfermedad de Milroy cuando este se presente. Se destacó como elemento importante que en este caso no se evidenciaron antecedentes familiares. Se empleó el tratamiento conservador como conducta fundamental a seguir, se evidenció en el paciente una notable mejoría clínica.

ABSTRACT Background: Primary congenital lymphedema is a rare condition with an important genetic component characterized by chronic edema of the affected area. Objective: To present a bilateral primary congenital lymphedema and discuss its origin. Case report: A case of bilateral primary congenital lymphedema was presented in a 2-year-old boy with no any family background of the disease. Its possible genetic causes were discussed since there are several mutations that explain its origin. Although genetic studies could not be performed to know the exact etiology, there is clinical evidence that it is not a Milroy's disease, unless it presents as a de novo mutation. The patient was followed up from diagnosis to the present. Conclusions: There are multiple genetic mutations that explain the origin of a primary congenital lymphedema, so it should not necessarily be Milroy's disease when present. A highlighted and important element was that in this case no any family background was evidenced. Conservative treatment was used as the essential conduct to follow up, a remarkable clinical progress was evidenced in the patient.

Introduction: Lymphedema is a chronic disease with a negative impact on the health of patients with lymphedema. It is considered an underestimated and sub-recorded health problem, which requires greater research and health efforts. Objective: Identify the characteristics of some parameters of humoral and cellular immunity in patients with lymphedema from Cerro municipality. Methods: A descriptive study was carried out in 48 patients living in Cerro municipality, who were attended in the external consultation of the National Institute of Angiology and Vascular Surgery in the period 2011-2015. The group was divided into 24 patients with lymphedema and 24 patients without the disease. The concentrations of immunoglobulins (A, G and M) and C-reactive protein were quantified in all of them. The test of delayed hypersensitivity was also perfomed. Non-parametric chi-square was used to associate immune state with the presence of lymphedema, etiology and lymphedema stages. Reliability was of 95 percent (p<0.05). Results: Female patients predominated (58.3 percent) and those of 60 years and older (29.2 percent). There was a higher frequency of recurrent lymphangitis (70.8 percent), predominantly stage II b secondary lymphedema (45.8 percent); lower right limb involvement (45.8 percent), with a significant difference of immunoglobulins (IgA and IgG); and frequency of anergic patients (91.7 percent), with positive C-reactive protein (45.8 percent). Conclusions: Patients with lymphedema have their immune system affected, more frequently the anergic ones, a decrease of IgA and IgG immunoglobulins, and positivity of C-reactive protein(AU)

Lipedema: más que un problema de "piernas gordas": actualización en la fisiopatología, diagnóstico y tratamiento quirúrgico / Lipedema: more than a problem of "fat legs": update in the pathophysiology, diagnosis and surgical treatment

Resumen El lipedema es una enfermedad común, frecuentemente subdiagnosticada, crónica y progresiva, que genera un gran deterioro en la calidad de vida. Consiste en el depósito anormal de tejido adiposo subcutáneo principalmente en las extremidades inferiores, afectando casi exclusivamente a mujeres. Sus síntomas principales son el dolor, la sensibilidad y la facilidad para producir equimosis. Desde el punto de vista fisiopatológico, existiría una susceptibilidad poligénica combinada con trastornos hormonales, microvasculares y linfáticos que pueden ser en parte responsables del desarrollo del lipedema. Se clasifica, según la distribución de la grasa en cinco tipos y, según la gravedad de la enfermedad, en cuatro etapas. El diagnóstico es eminentemente clínico y se debe diferenciar de otras patologías que producen aumento de volumen de las extremidades, especialmente el linfedema y obesidad. Es importante realizar un estudio funcional del sistema linfático cuando el diagnóstico es dudoso o para la etapificación del lipedema, por lo que la correcta interpretación de estos resultados es fundamental. El tratamiento está enfocado en disminuir la discapacidad y evitar la progresión, con el fin de mejorar la calidad de vida. Actualmente, la liposucción es un tratamiento efectivo para el lipedema, sin embargo, las técnicas empleadas para la lipectomía en el lipedema son diferentes a las técnicas utilizadas para la liposucción con fines estéticos. Las técnicas selectivas que respetan los vasos linfáticos tienen mejor rendimiento para reducir el volumen de grasa, retrasar la progresión, reducir el dolor, reducir la alteración marcha y mejorar la calidad de vida en estos pacientes.

Lipedema is a common, frequently under-diagnosed, chronic and progressive disease that generates an important detriment in quality of life. It consists in an abnormal deposit of subcutaneous adipose tissue mainly in the lower extremities, almost exclusively affecting women. Its main symptoms are pain, sensitivity and the ease of causing bruising. From the pathophysiological point of view, there would be a polygenic susceptibility combined with hormonal, microvascular and lymphatic disorders that may be partly responsible for the development of lipedema. It is classified according to the distribution of fat into five types and, according to the severity of the disease, in four stages. The diagnosis is eminently clinical and must be differentiated from other diseases that cause an increase in the volume of the extremities, especially lymphedema and obesity. It is important to carry out a study of the lymphatic system functionality when the diagnosis is not clear or for lipedema staging, so the correct interpretation of these results is essential. Treatment is focused on reducing disability and preventing progression, in order to improve quality of life. Liposuction is currently an effective treatment for lipedema, however, the techniques used for lipectomy in lipedema are different from the techniques used for liposuction for cosmetic purposes. Selective techniques that spare the lymphatic vessels have better results reducing fat volume, delaying progression, reducing pain, reducing gait disturbance, and improving quality of life of these patients.

Terapia complexa descongestiva no tratamento de linfedema pós-mastectomia / Descongestive complex therapy in the treatment of lymphedema after mastectomy

Introdução: O linfedema é a complicação mais frequente no pós-operatório do câncer de mama. Objetivo: Identificar a efetividade do uso da Terapia Complexa Descongestiva (TCD) na redução do volume e no tratamento intensivo do linfedema em pacientes submetidas ao procedimento cirúrgico com esvaziamento axilar devido ao câncer de mama. Métodos: Trata-se de uma revisão sistemática, para o qual foram consultados os bancos de dados Bireme e Pubmed, utilizando artigos científicos em português e inglês de revistas indexadas nas bases de dados Medline, Scielo, Lilacs, Register of Controlled Trials (Cochrane Central) e Physiotherapy Evidence Database (PEDro), publicados entre os anos de 2004 e 2019. Para a construção do trabalho foram incluídos estudos que estivessem disponíveis na íntegra, que a população alvo fosse composta por mulheres submetidas ao procedimento cirúrgico devido ao câncer de mama, com esvaziamento axilar, que apresentassem linfedema e que incluíssem em seus tratamentos, um protocolo fisioterapêutico de TCD. Também de forma independente, foi avaliada a qualidade metodológica dos estudos selecionados com a Escala de Qualidade de JADAD. Resultados: Atualmente, o padrão-ouro dentre as principais técnicas fisioterapêuticas utilizadas para o tratamento do linfedema é a TCD, a qual é composta por drenagem linfática manual, cuidados com a pele e unhas, bandagem de compressão e exercícios terapêuticos. Conclusão: A TCD é considerada o método mais utilizado e eficiente na redução do volume e no tratamento intensivo do linfedema pósmastectomia. (AU)

Introduction: The lymphedema is the most common postoperative complication of breast cancer. Objective: The present study aims to identify the effectiveness of the use of Complex Decongestive Therapy (CDT) in reducing volume and intensive treatment of lymphedema in patients undergoing axillary emptying due to breast cancer. Methods: This was a systematic review, for which Bireme and Pubmed databases were consulted, using scientific articles in Portuguese and English from journals indexed in Medline, Scielo, Lilacs, Register of Controlled Trials (Cochrane Central) databases and Physiotherapy Evidence Database (PEDro), all of them published between the years 2004 to 2019. For the construction of this study, we included articles available in full, with a target population consisting of women undergoing the surgical procedure due to breast cancer, with axillary emptying, who presented lymphedema and who included in their treatments a physical therapy protocol of CDT. Also, independently, the methodological quality of the studies selected was evaluated using the JADAD Quality Scale. Results: Currently, the gold standard among the main physiotherapeutic techniques used for the treatment of lymphedema is CDT, which consists of manual lymphatic drainage, skin and nail care, compression bandaging and therapeutic exercises. Conclusion: The CDT is considered the most used and efficient method for volume reduction and intensive treatment of post-mastectomy lymphedema. (AU)

Relação do Índice de Massa Corporal e Linfedema Secundário a tratamento cirúrgico do Câncer de Mama: estudo retrospectivo / Relationship of Body Mass Index and Secondary Lymphedema to Surgical Treatment of Breast Cancer: a retrospective study

INTRODUÇÃO: O câncer de mama é a neoplasia mais incidente na população feminina brasileira, sendo o linfedema uma de suas principais complicações cirúrgicas. OBJETIVO: Verificar a relação do índice de massa corpóreo e o desenvolvimento do linfedema no pós-operatório de câncer de mama, sua relação com o tipo de tratamento e ao tempo pós-cirúrgico. MATERIAIS E MÉTODOS: Foram levantados prontuários de 59 mulheres no período de maio de 2008 a fevereiro de 2009 utilizando dados da anamnese; exame físico; perimetria, volume estimado; relatos, sintomas e dados em prontuário. A análise foi feita por meio de médias e desvios padrões para as variáveis quantitativas e qualitativas (absoluta e relativa) e para verificação dos fatores de risco foi utilizado o Teste t de Student e Teste Qui-quadrado de Pearson com nível de significância de 5%. RESULTADOS: A frequência de linfedema foi de 47,5%, sendo que 40,7% eram obesas. Observou-se diferença significativa entre os grupos de linfedema e IMC (p=0,002). Nota-se ainda diferença significativa entre linfedema no grupo sem radioterapia de axila (p=0,003) e associação entre o tempo pós-cirúrgico e linfedema (p=0,006), sendo maior após 6 meses de cirurgia. CONCLUSÃO: Existe correlação entre obesidade e desenvolvimento do linfedema. Os tipos de tratamento parecem não ter influenciado o seu desenvolvimento e quanto mais tempo decorrido pós- cirurgia, maior o risco do seu aparecimento.

INTRODUCTION: Breast cancer is the most common neoplasm in the Brazilian female population, with lymphedema being one of its main surgical complications. OBJECTIVE: To verify the relationship between the body mass index and the development of lymphedema in the postoperative period of breast cancer, its relationship with the type of treatment received and the time elapsed from the surgery. MATERIALS AND METHODS: Medical records of 59 women were collected from May 2008 to February 2009 using data from anamnesis, physical exam; perimetry, estimated volume; reports, symptoms, and notes in medical records. The analysis was performed using means and standard deviations for the quantitative and qualitative variables (absolute and relative) and to verify the risk factors used, the Student's t-test and Pearson's chi-square test with a 5% significance level (0.05). RESULTS: The frequency of lymphedema was 47.5%, with 40.7% being obese. There was a significant difference between the groups of lymphedema and BMI (p=0.002). There is also a significant difference between lymphedema in the group without axillary radiotherapy (p=0.003) and an association between post-surgical time and lymphedema (p=0.006), being greater after six months of surgery. CONCLUSION: There is a correlation between obesity and the development of lymphedema. The types of treatment do not seem to have influenced their development, and the longer the surgery has elapsed, the greater the risk of their appearance.

Tratamiento supermicroquirúrgico del linfocele inguinal con linfedema intercurrente: restauración de la fisiología linfática / Supermicrosurgical approach to inguinal lymphocele with lymphedema: restoring the lymphatic physiology

Resumen Introducción: El linfocele es una patología que puede ocurrir por la disrupción linfática durante una cirugía, siendo frecuente luego de una linfadenectomía inguinal. Existen diversos enfrentamientos para prevenirlo o minimizarlo, sin embargo, los resultados son inconsistentes. Caso clínico: Reportamos el caso de una mujer, con linfocele recurrente en zona inguinal derecha y linfedema distal de la extremidad secundario a una biopsia ganglionar, tratado exitosamente mediante supermicrocirugía para restaurar el drenaje linfático. La extremidad inferior tenía un exceso de volumen de 7,03%. Se realizaron estudios preoperatorios con linfografía por resonancia magnética y linfografía con verde de indocianina para identificar los vasos linfáticos y realizar anastomosis linfático-venosas (ALV). Se identificaron tres vasos linfáticos aferentes y se realizó una capsulectomía total. Se realizaron tres ALV término-terminales supermicroquirúrgicas en zona inguinal y una ALV distal en pierna. Durante seguimiento no hubo recidiva del linfocele, evidenciándose una reducción del exceso de volumen de la extremidad afectada de un 105,26%. El linfocele inguinal y linfedema pueden ser tratados exitosamente mediante supermicrocirugía, restaurando el flujo linfático de manera fisiológica, evitando la recurrencia de linfocele y mejorando los síntomas del linfedema.

Introduction: Lymphocele may occur after the disruption of lymphatic channels during a surgical procedure. After inguinal lymphadenectomy are very common, and many different approaches have been tried to prevent or minimize the formation of lymphoceles with inconsistent results. Clinical Case: We report a case of a female patient who presented with right recurrent inguinal lymphocele and lower limb lymphedema after lymph-node biopsy that was successfully treated with lymphatic supermicrosurgery restoring the lymph flow. Lower extremity had an excess volume of 7,03% compared to the healthy contralateral limb. Preoperative study with magnetic resonance lymphangiography and indocyanine green lymphography were done to identify intraoperatively lymphocele afferent and distal lymphatic vessels to perform lymphovenous anastomosis (LVA). Three different afferent lymphatics were identified and total capsulectomy was performed. Three end-to- end supermicrosurgical LVA in the groin and one distal LVA on the leg were performed. The surgery was uneventful, and there were no postoperative complications. In the follow-up, no lymphocele was noticed and lymphedema had visibly reduced with a reduction of excess volume of 105.26%. Inguinal lymphocele and lymphedema can be successfully treated with supermicrosurgery since it is a physiological approach to restore the lymphatic flow, in order to avoid lymphocele recurrence and to improve lymphedema symptoms.

Prevención del linfedema posquirúrgico en cáncer de mama mediante rehabilitación fisioterapéutica: estudio comparativo entre drenaje linfático manual y kinesiotape / Prevention of postsurgical lymphedema in breast cancer through physiotherapeutic reha- bilitation: a comparative study between manual lymphatic drainage and kinesiotape

Se realizó un estudio con diseño cuantitativo, de tipo observacional descriptivo; cuya población de estudio estuvo constituida por 142 pacientes de sexo femenino, diagnosticadas con cáncer de mama en la Unidad Oncológica Solca-Chimborazo, durante el período 2014-2019; con el objeti - vo de describir el tratamiento fisioterapéutico en ese contexto de investigación. Los datos fueron recolectados a partir de las respectivas historias clínicas. A partir de 2015, se observó un predo- minio de pacientes adultos con edades comprendidas entre 36 y 65 años. De las 142 pacientes que conformaron la población estudiada, solo 5 desarrollaron linfedema posquirúrgico. La mayoría de las pacientes incluidas en el estudio fueron intervenidas quirúrgicamente (65); 59 de las cuales recibieron tratamiento de drenaje linfático manual. Entre la población elegida en la Unidad Oncológica de Solca-Chimborazo se evidenció que la aplicación de terapia de rehabili - tación mediante drenaje linfático manual posquirúrgico reduce la posibilidad de aparición de linfedema a largo plazo.

This research aimed to describe the physiotherapeutic treatment in this research context. A study was carried out with a quantitative design, of a descriptive observational type. The study popula- tion consisted of 142 female patients, diagnosed with breast cancer at the Solca-Chimborazo Oncology Unit, during the period 2014-2019. The data were collected from the respective medi- cal records. Since 2015, a predominance of adult patients aged between 36 and 65 years was observed. From the 142 patients that made up the study population, only 5 developed postsurgi- cal lymphedema. Most of the patients included in the study underwent surgery (65); 59 received manual lymphatic drainage treatment. Among the population chosen in the Solca-Chimborazo Oncology Unit, it was evidenced that the application of rehabilitation therapy through postope- rative manual lymphatic drainage reduces the possibility of long-term lymphedema develop - ment.

Atuação da Fisioterapia no Linfedema Neoplásico em Paciente com Câncer de Mama Metastático: Relato de Caso / Performance of Physiotherapy in Neoplastic Lymphedema in a Patient with Metastatic Breast Cancer: Case Report / Rendimiento de la Fisioterapia en la Linfedema Neoplásico en una Paciente con Cáncer de Mama Metastásico: Relato de Caso

Introduction: Breast cancer is one of the most common neoplasms among women in the world, accounting for 29.7% (66,280) of new cases in Brazil, and also corresponding to the main cause of death in this group (16.1%, 16,724). Neoplastic lymphedema is a malignant process of breast carcinoma, not very common but related to the disease progression. The gold standard treatment for lymphedema is the complex decongestive therapy (CDT) in order to reduce and maintain limb volume and increase the patient's quality of life. However, treatment for neoplastic lymphedema is little explored in the literature. The objective of this study was to analyze and report the impact of CDT on the control of neoplastic lymphedema symptoms and volume. Case report: Patient with breast cancer in palliative treatment and neoplastic lymphedema in the homolateral upper limb. The proposed physiotherapeutic treatment for this patient was the adapted CDT, which was split in two phases. The first phase was to reduce the lymphedema volume with skin care orientations, passive exercises (because of monoplegia and joint restriction) and compressive bandaging. Even if the lymphatic drainage was not applied, the treatment brought significant improvement in reducing the left upper limb volume with loss of 1,045,58 mL between the beginning and end of the first phase. The second phase was targeted to maintenance, indicating the use of compressive clamp to control the volume. Conclusion: The adapted CDT may be an option to minimize the volume of neoplastic lymphedema

Introdução: O câncer de mama está entre as neoplasias mais comuns entre as mulheres no mundo, representando 29,7% (66.280) dos casos novos no Brasil. Também corresponde à principal causa de óbitos (16,1%, 16.724) nesse grupo. O linfedema neoplásico é um processo maligno do carcinoma de mama não muito comum, significando progressão da doença. O tratamento padrão-ouro para o linfedema é a terapia complexa descongestiva (TCD) com a finalidade de reduzir e manter o volume do membro, além de aumentar a qualidade de vida do paciente. Entretanto, o tratamento para o linfedema neoplásico é pouco explorado na literatura. O objetivo deste estudo foi analisar e relatar o impacto da TCD no controle da sintomatologia e volume do linfedema neoplásico. Relato do caso: Paciente com câncer de mama em tratamento paliativo com linfedema neoplásico no membro superior homolateral. O tratamento fisioterapêutico proposto para essa paciente foi a TCD adaptada, dividida em duas fases. A primeira consistiu em reduzir o volume do linfedema, por meio de orientações de cuidados com a pele, exercícios passivos (em razão da monoplegia e restrição articular) e enfaixamento compressivo. Apesar de não ter sido realizada drenagem linfática, o tratamento demonstrou melhora significativa na redução do volume no membro superior esquerdo com perda de 1.045,58 ml entre o início e o final da primeira fase. A segunda fase foi dirigida à manutenção, indicando o uso da braçadeira compressiva para controle do volume. Conclusão: A TCD adaptada pode ser uma opção para minimizar o volume do linfedema neoplásico

Introducción: El cáncer de mama se encuentra entre las neoplasias más comunes entre las mujeres en el mundo, representando 29,7% (66.280) de nuevos casos en Brasil y es la principal causa de muerte en este grupo (16,1%, 16.724). La linfedema neoplásica es un proceso maligno de carcinoma mamario que significa progresión de la enfermedad. El tratamiento estándar para la linfedema es la terapia compleja descongestiva (TCD) con el fin de reducir el volumen de las extremidades y aumentar la calidad de vida del paciente, pero es poco explorado en la literatura. El objetivo de este estudio fue evaluar si el rendimiento de la TCD influiría en el volumen de linfedema. Relato del caso: El estudio fue un informe de una paciente con cáncer de mama y linfedema neoplásico en la extremidad superior homolateral. El tratamiento fisioterapéutico propuesto para este paciente fue el TCD adaptado, que se dividió en dos fases. La primera consiste en reducir el volumen de la linfedema mediante pautas de cuidado de la piel, ejercicios pasivos porque el paciente ha presentado plejía, restricción articular del hombro del miembro superior izquierdo y vendaje compresivo. Aunque en el estudio no se realizó drenaje linfático, el tratamiento mostró una mejoría significativa en la reducción de volumen en el miembro superior izquierdo con una pérdida de 1.045,58 ml entre el inicio y el final de la primera fase. La segunda fase dirigida al mantenimiento, en la que se indicó el uso de la pinza compresiva para control de volumen. Conclusión: La TCD adaptada puede ser una opción para minimizar el volumen y las quejas de un paciente con linfedema neoplásico

Conservative treatment of lymphedema: the state of the art / Tratamento conservador do linfedema: estado da arte

Abstract This article aims to discuss the possibilities of conservative and non-pharmacological treatments for lymphedema. A non-systematic review of the literature was carried out, including studies involving human subjects with different types of lymphedema. Several approaches to lymphedema treatment have been reported and Complex Decongestive Therapy (CDT) has been considered the most effective treatment for limb lymphedema. Other conservative treatments have been proposed such as Taping, Extracorporeal Shock Wave Therapy, Acupuncture, Photobiomodulation Therapy, Endermologie, Intermittent Pneumatic Compression, and Low-frequency, Low-intensity Electrotherapy. The choice of the therapeutic approach to be employed should consider lymphedema characteristics, the therapist's experience, and the patient's wishes. In addition, since this is a chronic condition, the patient must adhere to the treatment. To this end, the therapeutic proposal may be the key to better control of limb volume.

Resumo Este artigo tem como objetivo discutir as possibilidades de tratamentos conservadores e não medicamentosos para o linfedema. Foi realizada uma revisão não sistemática da literatura, com a inclusão de estudos realizados em humanos com diferentes tipos de linfedema. Várias abordagens de tratamento foram relatadas, sendo a terapia descongestiva complexa considerada o tratamento mais eficaz para o linfedema de membros. Outros tratamentos conservadores foram propostos, como taping, terapia por ondas de choque extracorpórea, acupuntura, fotobiomodulação, endermologia, compressão pneumática intermitente e eletroterapia de baixa intensidade e baixa frequência. A escolha da abordagem terapêutica a ser empregada deve considerar as características do linfedema, a experiência do terapeuta e os desejos do paciente. Além disso, como é uma condição crônica, o paciente deve aderir ao tratamento. Para isso, a proposta terapêutica pode ser a chave para um melhor controle do volume do membro.
