Resumo

Background: Population-based cancer registry (PBCR) data provide crucial information for evaluating the effectiveness of cancer services and reflect prospects for cure by estimating population-based cancer survival. This study provides long-term trends in survival among patients diagnosed with cancer in the Barretos region (Sa similar to o Paulo State, Brazil).Methods: In this population-based study, we estimated the one-and five-year age-standardized net survival rates of 13,246 patients diagnosed with 24 different cancer types in Barretos region between 2000 and 2018. The results were presented by sex, time since diagnosis, disease stage, and period of diagnosis.Results: Marked differences in the one-and five-year age-standardized net survival rates were observed across the cancer sites. Pancreatic cancer had the lowest 5-year net survival (5.5 %, 95 %CI: 2.9-9.4) followed by oeso-phageal cancer (5.6 %, 95 %CI: 3.0-9.4), while prostate cancer ranked the best (92.1 %, 95 %CI: 87.8-94.9), followed by thyroid cancer (87.4 %, 95 %CI: 69.9-95.1) and female breast cancer (78.3 %, 95 %CI: 74.5-81.6). The survival rates differed substantially according to sex and clinical stage. Comparing the first (2000-2005) and last (2012-2018) periods, cancer survival improved, especially for thyroid, leukemia, and pharyngeal cancers, with differences of 34.4 %, 29.0 %, and 28.7 %, respectively.Conclusion: To our knowledge, this is the first study to evaluate long-term cancer survival in the Barretos region, showing an overall improvement over the last two decades. Survival varied by site, indicating the need for multiple cancer control actions in the future with a lower burden of cancer. (AU)
