Gastric cancer is a leading cause of cancer-related mortality, and the presence of lymph node metastasis an important prognostic factor. Downregulation of RKIP has been associated with tumor progression and metastasis in several types of neoplasms, being currently categorized as a metastasis suppressor gene. Our aim was to determine the expression levels of RKIP in gastric tissues and to evaluate its impact in ...
INTRODUÇÃO: A realização de suturas e nós é das mais difíceis manobras cirúrgicas em videolaparoscopia. A habilidade de realizá-las durante os procedimentos videolaparoscópicos determinou grande expansão nas indicações laparoscópicas, bem como permitiu aos cirurgiões realizarem procedimentos de maior complexidade com mais segurança. O treinamento deve seguir as mesmas orientações do ensino de procedimentos bási...
RACIONAL: As alterações na digestão e perdas de nutrientes são aspectos relevantes na redução do peso e na manutenção do estado nutricional do paciente submetido à gastroplastia, mas poucos estudos estão disponíveis na literatura. OBJETIVO: Estudar as alterações sistêmicas decorrentes da redução de peso ao longo do tempo, após o tratamento cirúrgico. MÉTODO: Estudo tipo coorte prospectivo com amostra de 44 indi...
BACKGROUND: Advanced gastric cancer carries a poor-prognosis. The best extent of the node dissection and the value of postoperative adjuvant treatments remain open questions. AIM: To study the efficacy of adjuvant chemoradiation and the prognostic value of some clinico-pathological variables in gastric cancer previously submitted to surgery. METHODS: Retrospective single institution study of 69 patients with hi...
BACKGROUND: Gastric cancer (GC) is a predominately male disease. Usually for every female that suffers from this condition there are two males and occurred an increase in the number of females in last decades. Brazil is poor in data about this issue. AIM: To verify if in Brazil it happened: a) a change in the gender ratio and on the average age of the patients; b) an increase in the number of patients with 70 y...
BACKGROUND: Gastric volvulus is frequently an asymptomatic disease, and it is usually diagnosed during radiographic examination of the superior digestive tract. The acute form, however, can spawn serious and lethal clinical consequences. This disease is defined by the anomalous rotation of the stomach over itself, and it can be classified according to type, extension, direction, etiology, and clinical presentat...
Recently, the presence of microsatellite instability (MSI) has been reported in gastric cancer and associated with older age of presentation, distal tumor location, early disease staging, and better overall prognosis. Different characteristics in presentation and in tumor behavior may be explained by different genetic alterations during carcinogenesis of gastric cancer. Identification of specific genetic pathwa...
