PERFIL EPIDEMIOLÓGICO DOS ADENOCARCINOMAS GÁSTRICOS OPERADOS EM UM CENTRO DE REFERÊNCIA ESTADUAL PARAIBANO

Abstract

Gastric adenocarcinoma is a malignant tumor that originates from the cells of the glandular epithelial tissue of the stomach and accounts for 95% of malignant stomach neoplasms. It is more common in elderly individuals, but with associated factors that are still poorly understood. The objective of this monographic work was to evaluate the epidemiological profile of gastric adenocarcinomas treated at the Napoleão Laureano Hospital, located in the city of João Pessoa, PB. A retrospective and descriptive-analytical study was conducted at a tertiary referral hospital for Oncologic Surgery from July 2016 to June 2021, including all patients with resectable gastric adenocarcinoma and excluding those with advanced-stage gastric adenocarcinoma without surgical indication. The study was conducted by reviewing medical records, from which data with the following variables were extracted: age, sex, histological and morphological classification, tumor staging and stage, type of surgery, and postoperative deaths. The data underwent statistical analysis. After matching, a higher prevalence was observed in males, with a histological profile of low cellular differentiation and "signet ring" cell morphology. Furthermore, the most commonly observed staging during this period was Stage III, and the most performed surgical approach was subtotal gastrectomy. Therefore, it was concluded that between 2016 and 2021, there was a predominance of gastric adenocarcinomas, especially in patients over 50 years of age, amenable to resection surgery, mainly subtotal gastrectomy, with relatively few progressing to death.
