BUSTAMANTE-TEIXEIRA, Maria Teresa et al. Survival in gastric cancer patients in Campinas, São Paulo, Brazil. Cad. Saúde Pública [online]. 2006, vol.22, n.8, pp.1611-1618. ISSN 0102-311X.

This study analyzes the survival of gastric cancer patients in the city of Campinas, São Paulo State, Brazil. Data from the Campinas Population-Based Cancer Registry (RCBP) related to gastric cancer cases diagnosed from 1991 to 1994 were analyzed. Observed and relative survival rates were calculated, and to compare rates between different groups and international populations, the relative mortality risk was used. One-year relative survival rate for patients with gastric cancer was 33%, and five-year relative survival was 9%, confirming the poor prognosis of gastric cancer. Gender had no influence on survival, while the prognosis was better for young people. There was a gradient of severity from the localized to the metastatic state, not statistically significant. The group with undifferentiated adenocarcinomas had longer survival, with 47% of patients alive after the first year, whereas only 7% of those without a histological classification survived the first year after diagnosis. Compared with international results like the pool of European registries, the risk was greater, especially considering the five-year survival rates.
