1. The effect of positron emission tomography/computed tomography in axillary surgery approach after neoadjuvant treatment in breast cancer
SUMMARY OBJECTIVE: The aim of this study was to determine the role of positron emission tomography/computed tomography in the decision to perform axillary surgery by comparing positron emission tomography/computed tomography findings with pathology consistency after neoadjuvant chemotherapy. METHODS: Patients who were diagnosed for T1-4, cN1/2 breast cance

2. Predictive factors of melanoma thickness
Abstract Background: Melanoma thickness is a relevant prognostic marker that is crucial for staging and its calculation relies on the histopathological examination. There is a risk of thickness underestimation with an incisional biopsy if the latter is not performed on a tumor area where the thickness is maximal. This occurrence may have an impact on a ther

3. Revisiting surgical management of breast cancer in a geriatric population
Abstract OBJECTIVE: Breast cancer is a leading cause of death not only in the young population but also in the elderly. There are no consensus treatment guidelines for elderly breast cancer patients. We purposed to discuss surgical treatment options for breast cancer cases over 80 years concerning morbidity and mortality. METHODS: This retrospective study

4. How does the mitotic index impact patients with T1 melanoma? Comparison between the 7th and 8th edition of the American Joint Committee on Cancer melanoma staging system,
Abstract Background: The mitotic index is no longer used to classify T1 melanoma patients into T1a and T1b, so it should not be used to indicate sentinel node biopsy in these patients. Objectives: To evaluate patients with T1 melanoma who underwent sentinel lymph node biopsy and to compare those who were classified as T1a with those classified T1b, accordi

8. Association between tumor-infiltrating lymphocytes and sentinel lymph node positivity in thin melanoma
Abstract: Background: Sentinel lymph node biopsy in thin invasive primary cutaneous melanoma (up to 1mm thick) is a controversial subject. The presence of tumor-infiltrating lymphocytes could be a factor to be considered in the decision to perform this procedure. Objective: To evaluate the association between the presence of tumor-infiltrating lymphocytes

9. Comparison between hemosiderin and Technetium-99 in sentinel lymph node biopsy in human breast cancer
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 lymp

10. Sentinel lymph node biopsy in rats. Comparison between paraffin and frozen section analysis
PURPOSE: To simulate a lymph node metastasis in an animal model using activated carbon, assess their identification in frozen section analysis and compare with histopathological examination in paraffin. METHODS: Thirty two adult female rats were used. They received the carbon injection on its hind legs. Half of the rats was sacrificed on day one, and the ot

11. Padronização da pesquisa de linfonodos sentinelas em estômago por métodos combinados : estudo experimental em coelhos = Standardization of sentinel lymph node navigation in stomach by combined methods: experimental study in rabbits / Standardization of sentinel lymph node navigation in stomach by combined methods : experimental study in rabbits
Introdução - Com os estudos de Gould et al. (1960), Cabanas (1977) e Morton et al. (1992), estabeleceu-se o conceito da pesquisa do linfonodo sentinela. Esse se baseia na teoria de que ao identificar a presença ou ausência de metástase no primeiro linfonodo que recebe a drenagem linfática a partir do tumor (sentinela), poderia representar o estado de a

12. The impact of previous para-areolar incision in the upper outer quadrant of the breast on the localization of the sentinel lymph node in a canine model
OBJECTIVES: This paper discusses the influence of a para-areolar incision in the upper outer quadrant of the breast on the location of the sentinel lymph node in a canine model. METHODS: The sentinel lymph node was marked with technetium-99, which was injected into the subareolar skin of the cranial breast. After the marker had migrated to the axilla, an arc
