ABSTRACT
Este estudo objetivou analisar, por meio de uma revisão sistemática da literatura, a influência da reconstrução imediata na prevalência de linfedema após mastectomia em pacientes portadoras de câncer de mama. Foram analisados os mais relevantes estudos publicados originalmente em qualquer idioma até agosto de 2018, indexados às bases de dados US National Library of Medicine, Cochrane Central Register of Controlled Trials, Web of Science e Scientific Electronic Library Online. A amostra foi composta por 10 publicações que se adequaram aos critérios de inclusão e exclusão estabelecidos, incluindo 2.425 pacientes submetidas a apenas mastectomia e 2.772 pacientes submetidas à mastectomia associada à reconstrução imediata da mama. A prevalência de linfedema foi 20,95% nas pacientes submetidas a apenas mastectomia (n = 508) e de 5,23% nas pacientes submetidas à mastectomia associada à reconstrução imediata (n = 145), havendo diferença estatisticamente significativa (p < 0,001). Concluiu-se que a mastectomia associada à reconstrução imediata influencia positivamente o prognóstico das pacientes portadoras de câncer de mama, proporcionando um índice significativamente menor de linfedema, quando comparada à realização de apenas mastectomia.
This study aimed to analyze, through systematic review of literature, the influence of immediate reconstruction on the prevalence of lymphedema after mastectomy, in women living with breast cancer. The analysis considered the most relevant studies originally published, in any language, up to August 2018, indexed on the databases of the US National Library of Medicine, Cochrane Central Register of Controlled Trials, Web of Science, and Scientific Electronic Library Online. The sample comprised 10 publications that met the established criteria for inclusion and exclusion, including 2,425 patients who were subjected to mastectomy alone, and 2,772 patients who were subjected to mastectomy associated with immediate reconstruction of the breast. The prevalence of lymphedema was 20.95% in patients who had been subjected to mastectomy alone (n = 508), and 5.23% among those patients who were subjected to mastectomy associated with immediate reconstruction of the breast (n = 145), the difference being statistically significant (p < 0.001). We concluded that mastectomy, when associated with immediate breast reconstruction, has a positive influence on the prognosis of patients living with breast cancer, thereby providing a much lower rate of lymphedema when compared with mastectomy alone.

Resumen El linfedema asociado al cáncer de mama es una de las complicaciones más subestimadas y debilitantes del tratamiento de esta entidad. Ocurre como resultado de la interrupción del flujo linfático en asociación a otros factores. La incidencia varía dependiendo del tipo tratamiento recibido, existiendo mayor riesgo en los casos en los que se realiza mastectomía total, disección axilar, radioterapia, y en los pacientes en los cuales los ganglios están positivos para cáncer, hubo una mayor cantidad de linfonodos resecados, se utilizaron taxanos o padecen de obesidad. El diagnóstico clínico y a través de técnicas de imágenes es fundamental para evaluar el estado funcional del sistema linfático. Los objetivos principales en el manejo del linfedema son limitar la morbilidad del paciente, mejorar la funcionalidad y la calidad de vida. Existen procedimientos que buscan prevenir el desarrollo del linfedema asociado al cáncer de mama. Una vez establecido, el tratamiento puede ser conservador y quirúrgico. El tratamiento quirúrgico incluye procedimientos fisiológicos (reconstructivos) y resectivos. El éxito depende de una buena selección de los pacientes y la realización de un tratamiento individualizado. A continuación, se presenta una revisión en cuanto a la incidencia, factores de riesgo, estrategias diagnósticas y técnicas quirúrgicas con énfasis en el tratamiento microquirúrgico.
Breast cancer related lymphedema is one of the most underestimated and debilitating complications of the treatment of this entity. Occurs as result of the interruption of the lymphatic flow in association with other factors. The incidence varies depending on the type of treatment received; being a higher risk in cases in which total mastectomy, axillary dissection, radiotherapy are performed; and in patients in whom the lymph nodes are positive for cancer, there was a greater number of harvested lymph nodes, taxanes were used or in obese patients. Clinical diagnosis and imaging techniques are essential to assess the functional status of the lymphatic system. The main objectives in the management of lymphedema are to limit patient morbidity, improve functionality and quality of life. There are procedures that seek to prevent the development of breast cancer related lymphedema. Once established, the treatment can be conservative and surgical. Surgical treatment includes physiological (reconstructive) and excisional procedures. Success depends on a good selection of patients and the performance of an individualized treatment. The following is a review regarding the incidence, risk factors, diagnostic strategies and surgical techniques with emphasis on microsurgical treatment.

RESUMO Objetivo: analisar a experiência terapêutica inicial do transplante de linfonodos vascularizados em pacientes portadoras de linfedema de membros superiores secundário ao tratamento do câncer de mama e verificar se o posicionamento do transplante influencia o resultado cirúrgico. Métodos: ensaio prospectivo, comparativo, de duas modalidades terapêuticas em 24 pacientes portadoras de linfedema de membro superior após tratamento de câncer mamário, classificados como graus 2 e 3, segundo a Sociedade Internacional de Linfedema. Os dois tipos de procedimentos realizados foram: 1) reconstrução total da mama com retalho de perfurante da artéria epigástrica inferior (DIEP- deep inferior epigastric perforator flap) associado ao retalho linfonodal, em pacientes sem reconstrução mamária prévia ou com histórico de perda da reconstrução (posicionamento axilar); 2) retalho linfonodal inguinal isolado foi realizado em pacientes com reconstrução mamária finalizada ou sem o desejo de realizar a reconstrução da mama (posicionamento no punho). Resultados: a porcentagem de redução do volume do membro afetado foi de 20,1% (p=0,0370). O número de episódios infecciosos (celulites) também sofreu redução significativa, de 41% no período pré-operatório para 12,5% no pós-operatório (p=0,004). Não foram observadas diferenças entre os grupos proximal e distal. Conclusão: o transplante de linfonodos afetou positivamente a evolução pós-operatória de pacientes portadoras de linfedema secundário ao câncer de mama. Não foram observadas diferenças em relação ao posicionamento do retalho.
ABSTRACT Objective: to evaluate the initial therapeutic experience of transplantation of vascularized lymph nodes in patients with lymphedema of the upper limbs secondary to the treatment of breast cancer, and to verify if the positioning of the transplant influences the surgical result. Methods: we conducted a prospective, comparative test of two therapeutic modalities, with 24 patients with lymphedema of the upper limb after breast cancer treatment, classified as grades 2 and 3, according to the International Lymphedema Society. The two types of procedures performed were: 1) total breast reconstruction with - deep inferior epigastric perforator (DIEP) flap associated with lymph node flap, in patients with no previous breast reconstruction or loss of previous reconstruction (axillary positioning); 2) isolated inguinal lymph node flap performed in patients with completed breast reconstruction or without the desire to perform the breast reconstruction (wrist positioning). Results: the reduction percentage of the affected limb volume was 20.1% (p=0.0370). The number of infectious episodes (cellulites) also decreased significantly, from 41% in the preoperative period to 12.5% in the postoperative one (p=0.004). There were no differences between the proximal and distal groups. Conclusion: the transplantation of lymph nodes positively affected the postoperative evolution of patients with lymphedema secondary to breast cancer. We observed no differences in relation to flap positioning.
