Abstract:BackgroundIn several countries, such as Brazil, the oncological diagnosis usually occurs at an advanced stage of the disease. Thus, the aim of this study was to investigate temporal trends and factors associated with the cancer diagnosed at stage IV in Brazil in two decades.MethodsSecondary-based study, with time series analysis for trend assessment and cross-sectional of factors associated with diagnosis of female breast, prostate, cervix uteri, colorectal, lung, stomach, lip and oral cavity, thyroid, esophagus or corpus uteri at stage IV.Results1,218,322 cases were evaluated. The types of cancer with the highest proportion of stage IV at diagnosis in men and women, respectively, were: lung (53.7% and 57.4%), stomach (48.4% and 45.0%) and lip/oral cavity (53.5% and 43.4%). Most showed an increasing trend of annual percent change of cancer diagnosed at stage IV, being more pronounced in corpus uteri cancer (2013–2019: +7.4%, p < 0.001). The odds of cancer diagnosed at stage IV were associated with different factors, according to primary tumor site, but marked by the inverse association with female sex odds ratio (OR) ranging from 0.42 to 0.91, p < 0.001] and direct association in cases with < 7 years of study (OR ranging from 1.08 to 1.81, p < 0.001), living without a partner (OR ranging from 1.06, p < 0.050 to1.27, p < 0.001), living in the South and Southeast regions (OR ranging from 1.04 to 1.13, p < 0.001), with more than one tumor (OR ranging from 1.19, p < 0.050 to 1.54, p < 0.001) and treated in Centers of High Complexity in Oncology (OR ranging from 1.03, p < 0.050 to1.24, p < 0.001).ConclusionThere was a high frequency of cancer diagnosed at stage IV and an increasing trend in different cancer types, which were associated with distinct sociodemographic, lifestyle, and clinical factors.
