Hypothesis
The level of unstaged cancer incidence depends on the type of reporting source and demographic variables.
Conclusion
The level of unstaged cancer is negatively associated with cancer lethality and varies by reporting source.
Supporting Evidence
- Approximately 9.4% of males and 7.2% of females had unstaged cancer.
- The adjusted rate of unstaged cancer was 60% higher in males than females.
- Unstaged cancer rates increased with age and decreased with household income.
- Blacks had an 11% higher rate of unstaged cancer compared to Whites.
- Hispanics had an 11% higher rate of unstaged cancer compared to non-Hispanics.
- There was a significant negative association between unstaged cancer and 5-year relative survival rates.
Takeaway
Some cancers don't have a stage when diagnosed, and this study looks at how often that happens based on where the information comes from and who the patients are.
Methodology
Data was collected from 22 cancer registries and analyzed using Poisson regression.
Participant Demographics
Participants included 2,719,800 males and 2,727,223 females diagnosed with malignant cancer from 2015 to 2021.
