RESUMO
Gastric cancer is a common and deadly cancer. Several factors are associated with its prognosis; however, controversy exists about the role of microsatellite instability (MSI). We aimed to determine the 5-year overall survival (OS) of MSI in gastric adenocarcinoma. A cross-sectional study was carried out on gastric adenocarcinoma in clinical stages I to III treated with D2 gastrectomy between 2010-2013. MSI was demonstrated by immunohistochemistry. We performed a survival analysis comparing cases with and without MSI. From 102 cases, 9.8% showed MSI. The median age was 63 years (range 33-91 years), and 57.8% were men. The more prevalent site of occurrence was the antrum (46.1%), 78.5% of the cases presented in stage III, 47.1% were of the diffuse type, 45.1% were of an intestinal type, and 7.8% were mixed. MSI cases were associated with lower clinical stages (stages I-II) and with better 5-year OS (100 vs. 47 months, p = 0.017). In a multivariate analysis, MSI was independently associated with better survival (HR = 0.209, 95% CI: 0.046-0.945, p = 0.042). MSI gastric cancers presented in early clinical stages and had favourable prognosis compared with non-MSI cancers.
RESUMO
El Síndrome de Apert llamado también acrocefalosin-dactilia tipo I, está caracterizado por craneosinostosis, sindactilia simétrica en las cuatro extremidades, retardo mental, alteraciones cutáneas y maxilofaciales; está ocasionado por una mutación en el gen receptor 2 del factor de crecimiento fibroblástico FGFR2 expresándo-se en forma autosómico dominante (AD).Caso Clínico: Se presenta caso de recién nacido masculino, Capurro de 38 semanas aproximadamente, con las características fenotípicas clásicas de este síndro-me: como es la acrocefalia y la sindactilia en manos y pies.
Apert syndrome also called acrocephalosyndactyly Type I is characterized by craniosynostosis , symmetric syndactyly in all four limbs , mental retardation , skin and maxillofacial disorders ; It is caused by a mutation in the gene receptor 2 fibrobroblástico growth factor expres-sing FGFR2 autosomal dominant (AD ) .Case report: as is the acrocephaly and syndactyly in the hands and feet of newborn male case, Capurro of 38 weeks approximately, with classical phenotypic characteristics of this syndrome is presented as is the acro-cephaly and syndactyly in hands and feet.
