Linfonodo sentinela após mamoplastia de aumento pela via transaxilar: estudo prospectivo controlado por meio de linfocintilografia em 43 pacientes

Abstract: OBJETIVO: Verificar se a mamoplastia de aumento pela via transaxilar apresenta potencial de prejudicar a identificação futura do linfonodo sentinela. MATERIAIS E MÉTODOS: Estudo prospectivo controlado em que foram selecionadas 22 pacientes divididas em grupo pós-mamoplastia e grupo controle, totalizando 43 mamas (22 no grupo pós-mamoplastia e 21 no grupo controle) avaliadas por meio de linfocintilografia imediatamente após injeções periareolares de fitato-99mTc. Os testes estatísticos consideraram como diferen… Show more

“…This facilitates the monitoring of the proliferative profi le and represents a gain in relation to the surgical orthotopic transplantation, besides allowing clinical and image evaluations, also collaborating in the detection of primary mammary tumor, lymph node staging, evaluation of treatment response, and detection of recurrent and metastatic disease. Moreover, the present protocol facilitates the transplantation procedures, avoiding occurrence of metastasis by the passage of needles with bevel or transfi xation to unwanted adjacent anatomic sites, such as muscle, fatty tissue and viscera from the abdominal cavity, reducing discomfort to the animals.Additionally, SLN is defi ned as the fi rst LN to receive lymphatic drainage from breast cancer, due to the ordered progression of cells through the lymphatic system[66][67][68][69][70]. In view of this, we selected the 5 th mammary gland due to the proximity of the right subiliac node[36].…”
