CLINICAL-EPIDEMIOLOGICAL AND MORTALITY PROFILES BY GASTRIC CANCER IN BRAZIL: COMPARATIVE ANALYSIS BETWEEN STATES

Introduction: In Brazil, gastric cancer is the third most frequent neoplasm among men and the fifth among women. Adenocarcinoma is about 95% of the cases. Excess weight, alcohol consumption, smoking and pre-existing illnesses are important risk factors. Objective: Draw clinicalepidemiological and mortality profiles of gastric cancer cases in Brazil in the period between 2014 and 2018. Methods: Descriptive and cross-sectional study using the Registro de Cancer de Base Populacional (RCBP), with variables related to gastric cancer, in the period 2014-2018, throughout the country. The incidence coefficient (IC) per 100,000 inhabitants was calculated according to the latest census by the Brazilian Institute of Geography and Statistics. Furthermore, the Atlas of Cancer Mortality from the DATASUS database was used, selecting the crude mortality rates for gastric cancer, per 100,000 men and women, in the same period. Results: In the period 7,788 cases of gastric cancer were registered in Brazil. However, 15 states didn’t have data analyzed due to lack of registration on the platform. Among the registered, São Paulo had the highest incidence, with 2,963 cases and IC 7.18, followed by Pará, with 1334 cases and IC 17.59. Males were prevalent over females. About age, 7 states plus the Federal District (FD) showed a predominance in the age group of 6069 years, which represents 22.68% of the total number of cases in the country. Mato Grosso and Pernambuco had a prevalence of 70-79 years old, and Santa Catarina and Sergipe were between 50-59 years old. Furthermore, only 4 states had any record under 20 years. Regarding the clinical stage of the disease, except for cases without recorded information, 9 states had higher records of metastatic disease. Finally, regarding mortality, the states that stood out were Ceará (5.6), Amapá (4.9), Rio Grande do Sul (4.9), Santa Catarina (5.8) and Paraná (5.9), among which, the first 3 do not present data in the RCBP. Conclusion: From the data obtained, it was observed that only 11 of the Brazilian states plus the FD added records of new cases of gastric cancer in the RCBP within the study period. Ceará, Amapá and Rio Grande do Sul are among the states with the highest mortality rates, however, none of the three have data in the RCBP, which makes it impossible to understand the reasons that cause this high coefficient.
