【 摘 要 】

Background:Stomach cancer is among the most frequent, is a leading cause of mortality in low- andmiddle-income countries. Assessing its survival is important to guide evidence-basedhealth policies.Aims:To estimate stomach cancer survival in Colombia (2014-2019) with data from theNational Cancer Information System (NCIS) and in Cali with data from the CaliPopulation Cancer Registry (RPCC) (1998-2017).Methods:NCIS estimated the overall 3-year net survival for 8,549 people, while RPCC estimated5-year net survival for 6,776 people.Results:The 3-year net survival was 36.8% (95% CI: 35.5-38.1). Net survival was higher in peoplewith special insurance (61.7%; 95% CI: 44.8-74.8) or third payer (40.5%; 95% CI: 38.7-42.3) than state insurance (30.7%; 95% CI: 28.7-32.8). It was also higher in women andpeople diagnosed at early stages. Multivariable analysis showed consistency with survivalestimations with a higher risk of death in men, people with state insurance, and diagnosedat advanced stages. In Cali, the 5-year net survival remained stable in men during the last20 years. In women the 5-year net survival in women increased 8.60 percentage points,equivalent to a 50% increase compared to the 1998-2002 period. For 2013-17, it was19.1% (95%CI: 16.2-22.2) in men, and 24.8% (95% CI: 20.4-29.3) in women.Conclusions:Population survival estimates from the RPCC were lower than those observed in theNCIS. The differences in their methods and scope can explain variability. Nevertheless,our findings could be complementary to improve cancer control planning in the country.
