PURPOSE: To assess the safety and potential equivalence of the use of hemosiderin compared to the Technetium-99 in sentinel lymph node biopsy in human breast cancer. METHODS: Non-random sample of 14 volunteer women diagnosed with breast cancer with primary tumors (T1/T2) and clinically tumor-free axilla were submitted to the identification of sentinel lymph node using hemosiderin obtained from autologous blood ...
PURPOSE: To compare two rat ovary cryopreservation techniques (vitrification vs. slow freezing) and two postmenopausal stages (early vs. late) with regard to graft take.METHODS:Thirty-three Wistar rats were submitted to bilateral oophorectomy. One ovary was submitted to histological analysis while the other was cryopreserved by slow freezing or vitrification. The cryopreserved ovary was thawed and reimplanted i...
OBJETIVO: Comparar o consumo alimentar de dois grupos de mulheres portadoras de câncer de mama atendidas em dois períodos distintos: 1999-2004 e 2005-2009. MÉTODOS: Estudo documental, com abordagem descritiva e comparativa. Foram coletados dados de identificação e de ingestão alimentar nas fichas de 154 pacientes portadoras de câncer de mama atendidas em serviços de referência de Fortaleza (CE): 66 no período d...
PURPOSE: To check the rate of sentinel lymph node (SLN) identification in patients with locally advanced breast cancer who underwent neoadjuvant chemotherapy comparing intraoperative contact cytology (imprint) and embedded in paraffin and validation of methods. METHODS: A cross-sectional validation of diagnostic test involving 34 patients from the outpatient clinic of the Maternity School Assis Chateaubriand. T...
PURPOSE: This paper aims to study and define the experimental model of sentinel lymph node biopsy of the vulva in bitches. METHODS: 0.2 ml of 99mTc phytate was injected intradermally, using a fine gauge insulin needle in the anterior commissure of the vulva. Thirty minutes after 99mTc injection, the inguinal mapping was performed using a gamma probe. After this, 0.5 ml of blue dye (bleu patenté V Guerbet 2.5%) ...
INTRODUÇÃO: Cada vez mais são realizadas reconstruções imediatas da mama pós-tratamento do câncer. Para as mastectomias radicais, há várias técnicas consagradas. Na quadrantectomia, as opções de reparação do defeito vão do fechamento primário à utilização de técnicas de cirurgia oncoplástica. Para os tumores dos quadrantes externos, a opção de rotação de todo o músculo latíssimo do dorso é desnecessária, uma ve...
INTRODUÇÃO: A única perspectiva de cura do câncer gástrico ainda é o tratamento cirúrgico - gastrectomia associada com linfadenectomia ampliada -, embora tal procedimento possa levar a alto índice de morbidade ou mortalidade. Atualmente, a pesquisa do linfonodo sentinela para o câncer gástrico inicial (EC T1/T2) apresenta argumentos que podem está modificando esta conduta. OBJETIVO: Realizar revisão bibliográfi...
PURPOSE: To evaluate and present our initial results of a new marker (hemosiderin) for mammary sentinel lymph node identification in an experimental model. METHODS: Skins mapped like a lymphatic duct draining to the axilla in patients submitted to breast biopsy, in our mastology service, stimulated us to try it in an animal model (female dogs). Our theory was that some blood derivate (hemosiderin) was captured ...
PURPOSE: To identify the lymph nodes positioned along the internal mammary vessels in isolated sternum of human cadaver and to standardize the surgical approach to those nodes, in order to establish anatomical landmarks to be used with the current techniques of mammary gland sentinel lymph node detection. METHODS: Ten sternum plates removed from unclaimed cadavers were used in this study. Sternal plates were re...
Pesquisa do Linfonodo Sentinela (LS) tem se mostrado efetiva na avaliação axilar nas portadoras de neoplasia mamária. O LS negativo torna desnecessário o esvaziamento axilar. OBJETIVO: Identificar o LS da região subareolar da mama em cadelas utilizando corante azul patente (AP), Tecnécio Tc99m ou a associação de ambas as técnicas e compará-las quanto à sensibilidade na detecção do linfonodo sentinela. MÉTODOS: ...
