O estudo histopatologico dos linfonodos axilares continua sendo o melhor parâmetro para a avaliacao do prognostico do câncer de mama. No entanto, como em cerca de 80% das pacientes com tumores de ate 2 cm os linfonodos nao apresentam comprometimento neoplasico, foi proposta, ha alguns anos, a disseccao do linfonodo sentinela, reduzindo a morbidade cirurgica nas pacientes com resultado negativo. Recentemente, esta tecnica cirurgica disseminou-se no Brasil, mas existem duas questoes importantes: qual a probabilidade de resultado falso-negativo, ou seja, deixar de identificar um linfonodo comprometido pelo câncer, e se o subestadiamento pelo resultado falso-negativo exporia a paciente ao risco de recidiva axilar ou mesmo metastase a distância, pela utilizacao de terapia cirurgica e adjuvante menos agressiva. A revisao da literatura mostra que a taxa de falsos-negativos varia de 5 a 10%, sendo o principal fator associado a falta de experiencia do cirurgiao. Embora as recidivas axilares sejam raras, nao e ainda possivel avaliar o efeito a longo prazo de deixar de retirar linfonodos comprometidos, devido ao curto periodo de seguimento. Portanto, a recomendacao e que o linfonodo sentinela so seja realizado por cirurgioes com experiencia comprovada pela pequena taxa de resultados falso-negativos.read more

Sentinel lymph node biopsy in early breast cancer surgery – Working with the risks of vital blue dye to reap the benefits
TL;DR: A retrospective review was undertaken of the different levels of anaphylaxis associated with vital dyes as well as their benefits in SLNB to ensure that SLNB remains a highly sensitive procedure.

TL;DR: Assessment of the sentinel lymph node biopsy accuracy in female dogs suffering from mammary carcinoma revealed that the SLNB technique offers high sensitivity in the early detection of metastases, allowing higher precision in the staging of oncological patients and, therefore, offering higher chances of survival.

TL;DR: An optimal orthotopic cancer model for breast cancer in the immunocompetent Swiss mouse is established, describing the detailed microanatomy of the mammary glands, the sentinel lymph node and lymphatic mapping, evaluating histopathological changes and characterizing the tumor by computed microtomography and interleukins expression.

TL;DR: In this paper, the authors evaluated body image and sexual function on women after surgery treatment of breast neoplasm that developed to lymphedema, and found that women's sexual function was related to body image.

TL;DR: Sentinel lymph node biopsy is associated with reduced arm morbidity and better quality of life than standard axillary treatment and should be the treatment of choice for patients who have early-stage breast cancer with clinically negative nodes.

TL;DR: Results are comparable to those obtained from multicenter studies evaluating SNB before systemic therapy and suggest that the sentinel node concept is applicable following neoadjuvant chemotherapy.

TL;DR: Axillary LR after SLNBiopsy, with or without ALND, is a rare event, and this low relapse rate supports wider use of SLN biopsy for breast cancer staging, and there is a low-risk subset ofSLN-positive patients in whom completion ALND may not be required.
