Background: This study provides descriptive epidemiological data of invasive colon and rectum cancer cases diagnosed from 1999 to 2014 in the United States of America.
Methods: This is a retrospective descriptive epidemiological analysis of invasive colon and rectum cancer cases recorded in the Centres for Disease Control and Prevention from 1999 to 2014. The statistical analyses were performed using descriptive statistics to calculate the overall age-adjusted incidence rate stratified by state, race, and gender.
Results: The state of New Jersey, Pennsylvania, Illinois, Iowa, Nebraska, West Virginia and Kentucky had the highest overall age-adjusted incidence rate of invasive colon and rectum cancer among male and female White and Black American, from 1999 to 2014. The state of Connecticut, Detroit, and Hawaii had the highest overall age-adjusted incidence rate of invasive colon and rectum cancer among male and female Hispanic, from 1999 to 2014.
Conclusion: This study revealed that the best geographic areas in the United States of America for studying the most important risk factors for invasive colon and rectum cancer among male and female White and Black American are the state New Jersey, Pennsylvania, Illinois, Iowa, Nebraska, West Virginia and Kentucky, while the best geographic areas for studying the most important risk factors for invasive colon and rectum cancer among male and female Hispanic are the state of Connecticut, Detroit, and Hawaii. Therefore, multiple case-control studies adjusted by race and gender should be conducted in the mentioned states to identify the major risk factors that can be controlled.
