IntroductionGastric cancer is the fifth most common malignant neoplasm and the third leading cause of cancer‐related death worldwide. In Peru, its incidence is 15.8 per 100,000 population, and it is associated with high mortality rates, especially in areas with low socioeconomic status. The aim of this study was to compare preoperative, postoperative, and anatomopathological staging results and their relation to disease recurrence and survival.MethodsWe conducted a retrospective cohort study of patients undergoing surgery for gastric cancer with a definitive postoperative anatomopathological diagnosis from 2005 to 2014 at the Hospital Nacional Luis N. Sáenz. Statistical analyses included descriptive and correlation statistics using the κ index, determination of associations between preoperative and postoperative staging and surgical reintervention and recurrence using the χ2 test, as well as Kaplan Meier survival analysis.ResultsThere was little correlation between preoperative staging and final anatomopathological diagnosis, while there was a good correlation with postoperative staging. A significant association was found between preoperative staging and cancer recurrence. In the survival analysis, survival was lower among patients with underestimated staging.ConclusionsThe survival of patients with gastric cancer can be affected by an overestimation of preoperative staging, therefore improvements in preoperative staging could lengthen the survival of patients undergoing gastric cancer surgery.
Entre las causas de abdomen agudo de origen vascular, la isquemia mesentérica aguda (IMA) permanece como un desafío diagnóstico y terapéutico. La variable presentación de síntomas y signos no evidentes en la fase inicial, exámenes auxiliares que pueden desviar la atención a otras patologías y su baja frecuencia pueden ser algunos factores responsables de un retardo en el diagnóstico con consecuencias en el pronóstico de la enfermedad llegando a tener una mortalidad de 50 a 100%(1, 2). En países de primer mundo puede ser el hallazgo en 2.1% de exploraciones quirúrgicas por abdomen agudo o ser causa del 0.1% de hospitalizaciones(3). En todo caso aumenta con la edad(4) y en nuestro país la población adulta mayor de 60 años constituía el 5.7% en 1950 pero el 2019 representa el 12.4% de la población(5), tendencia que continuará progresando cada año, por lo que se espera aumente su frecuencia como causa de abdomen agudo quirúrgico en nuestro población.
