Papel de KLF6, Como Factor de Predicción Precoz en Cáncer Colorrectal Humano
Provedor de dados: 77

El cáncer colorrectal (CCR) constituye el segundo tipo de cáncer más frecuente en la población europea. Actualmente no existe biomarcadores moleculares que se pueden utilizar para la detección temprana del cáncer de CCR. KLF6 es un supresor tumoral relacionado con varios tipos de cánceres. Nuestra hipótesis plantea que KLF6 puede ser un excelente marcador en el diagnóstico precoz de CCR. Para estudiar la implicancia de KLF6 en el CCR, se seleccionaron 15 biopsias de cada estadio (T1,T2 y T3) de los archivos del Servicio de Anatomía Patológica del Hospital Central de la Defensa Gómez-Ulla, las cuales presentaban áreas de tejido afectado (tumor) y áreas sin afectación (no tumorales). Para ello se realizó un estudio histológico, inmunohistoquímico y RT-PCR,...

Pure Micropapillary Rectal Carcinoma with CK7 and CK20 Coexpression and Loss of CDX2 Reactivity
Provedor de dados: 77
Autores: Lino-Silva,Leonardo Saúl.
The micropapillary carcinoma is regarded as an aggressive variant of adenocarcinoma in any location. Histologically is characterized by papillary cell clusters surrounded by clear spaces. The reported proportion of micropapillary carcinoma component to the entire tumor ranged from 5 to 80% and no pure cases has been reported. There are near of 130 cases reported to date in colorectum. We experienced a patient with a pure micropapillary carcinoma showing coexpression of CK7, CK20, and absence of CDX2, which had an aggressive neoplasm with extense perineural, vascular and lymphatic invasion also extensive nodal metastasis. The presence of a micropapillary carcinoma in the colorectum seemed to be closely related with nodal metastasis, similar to the case for...

Adenocarcinoma papilar em cão: relato de caso
Provedor de dados: 195
Autores: dos Santos, Andreza Heloísa; Ximenes, Raquel Guedes; Cardoso, Maria Carolina Silveira; de Andrade, Rachel Livingstone Felizola Soares; Morschel, Fernando.
É relatado o diagnóstico de adenocarcinoma papilar em cão. Uma cadela de dez anos e raça indeterminada foi atendida no setor de emergência do Hospital Veterinário da Faculdade Pio Décimo, Aracaju-SE, com histórico de dispneia há três dias. Ao exame clínico, foi detectada ortopneia, cianose, TR 39,2°C, FC 150/bpm com hipofonese cardíaca, SPO250%, PAS 10mmHg. Foi realizada oxigenioterapia, fluidoterapia e toraconcentese com retirada de líquido avermelhado. O animal permaneceu estável com TR 38,2°C, FC 155/ bpm, SPO298% e PAS 12mmHg. Exames efetuados demonstraram anemia normocítica normocrômica, neutrofilia com desvio à esquerda, monocitopenia, e eosinopenia. Radiografia torácica em projeções latero-lateral e ventro-dorsal evidenciou uma massa em região de...

Concomitant prostatic schistosomiasis and sdenocarcinoma: case report and review
Provedor de dados: 55
Autores: Basílio-de-Oliveira,Carlos Alberto; Aquino,Armando; Simon,Eliane Francine; Eyer-Silva,Walter A.
The term schistosomiasis encompasses a group of infectious disorders caused by five species of the genus Schistosoma, a blood trematode of outstanding importance in tropical areas. Some of these disorders have long been associated with malignant neoplasia, the most striking association being between disease caused by Schistosoma haematobium, the predominant etiological agent of urinary schistosomiasis, and squamous cell carcinoma of the bladder, a relatively uncommon vesical cancer in non-endemic areas. Four cases of simultaneous adenocarcinoma and schistosomiasis of the prostate have been previously reported (S. haematobium in three and S. mansoni in one). We report a fifth case of concomitant adenocarcinoma and schistosomiasis of the prostate in a...

Comparison of histological and molecular diagnosis of Helicobacter pylori in benign lesions and gastric adenocarcinoma
Provedor de dados: 58
Autores: César,Ana Cristina Gobbo; Cury,Patrícia Maluf; Payão,Spencer Luiz Marques; Liberatore,Paula Rahal; Silva,Ana Elizabete.
Helicobacter pylori colonization is associated with chronic gastritis, peptic ulcers, intestinal metaplasia, adenocarcinoma and lymphoma of the stomach. The objective of this study was to compare the results of the routinely used histology with molecular diagnosis for the detection of H. pylori. Eighty samples from gastric lesions (chronic gastritis, atrophic gastritis, gastric ulcer, and intestinal metaplasia), 18 gastric adenocarcinoma and 10 normal mucosa H. pylori-negative (control) samples were obtained. All samples were examined histologically (hematoxylin-eosin and Giemsa staining), and PCR amplifications of the species-specific antigen gene (H3H4) and urease A gene segment (H5H6) of H. pylori were made, using the human gene CYP1A1 for DNA quality...
