Comparison between hemosiderin and Technetium-99 in sentinel lymph node biopsy ...
Vasques,Paulo Henrique Diógenes; Alves,Mayara Maia; Aquino,Ranniere Gurgel Furtado de; Torres,Roberto Vitor Almeida; Bezerra,José Lucas MartinsPURPOSE: 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 ...
Experimental canine model for sentinel lymph node biopsy in the vulva using tec...
Aquino,José Ulcijara; Pinheiro,Luiz Gonzaga Porto; Vasques,Paulo Henrique Diógenes; Rocha,João Ivo Xavier; Cruz,Diego Alves; Beserra,Hugo Enrique OrsiniPURPOSE: 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%) ...
Hemosiderin: a new marker for sentinel lymph node identification
Pinheiro,Luiz Gonzaga Porto; Oliveira Filho,Renato Santos de; Vasques,Paulo Henrique Diógenes; Filgueira,Pedro Henrique de OliveiraPURPOSE: 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 ...
