ABSTRACT Introduction: Gastric cancer is still the third cause of death worldwide due to malignant neoplasms. Its prognostic indices have not yet been well defined for surgical intervention in terms of stratifying the intensity of chronic inflammation. The Glasgow Prognostic Score (GPS) and O-POSSUM and P-POSSUM Indices may constitute these standardizations and were tested to assess the association between them and the prognosis after curative gastrectomy. Method: Retrospective observational study, analysing medical records of patients with gastric adenocarcinoma who underwent gastrectomy, from 2015 to 2021, in two hospitals in Rio de Janeiro. Surgical extension, pre, peri and postoperative clinical and laboratory data were observed, up to 30 days after surgery. Patients were layered by GPS and compared according to the Clavien-Dindo (CD) classification. Logistic regression was performed to test the association between the outcome and independent variables. Results: Of the 48 patients, 56.25% were female. There was difference between the groups regarding surgical extension and GPS (both with p<0.001), while O-POSSUM, P-POSSUM and age showed no difference. Factors associated with CD ≥ III-a complication in the univariate analysis were GPS (OR: 85,261; CI: 24,909- 291,831) and P-POSSUM (OR: 1,211; CI:1,044-1,404). In the multivariate analysis, the independent factors associated with CD ≥ III-a were GPS (OR:114,865; CI: 15,430-855,086), P-POSSUM (OR: 1,133; CI: 1,086-1,181) and O-POSSUM (OR: 2,238; CI: 1,790-2,797). Conclusion: In this model, GPS, P-POSSUM and O-POSSUM predicted serious surgical complications. There is a need for further studies to establish strategies to minimize the inflammatory response in the preoperative period.
