Effect of health check-up on early detection of colorectal or breast cancer

Abstract

Objective To explore the effect of health check-up on screening and early detection of colorectal or breast cancer. Methods A total of 4 179 health check-up receivers were enrolled in this investigation. Basic health information was linked to the Shanghai Cancer Registry System and confirmed cancer diagnosis through Access 2007. Excel 2013 was used to analyze cancer detection rate, ranking, age and sex distribution and early stage proportion. Results During 2011 and 2012, 81 cancer cases were identified, with a detection rate of 47.47/100 000. The highest detection rate was found in 60-69 years old group (105.36/100 000), and male:female ratio was 1.25∶1. One colorectal cancer was diagnosed, resulting in a detection rate of 0.79/100 000. Eleven breast cancers were diagnosed, with a detection rate of 17.22/100 000. Early stage breast cancer accounted for 71%, which was higher than average level between 2005-2009 (33%). Conclusion Detection rate of colorectal cancer among health check-up receivers was very low, which is inconsistent with the high incidence of colorectal cancer in Shanghai. Fecal occult-blood test should be performed during health check-up, which may increase colorectal cancer detection. Moreover, health check-up may contribute to early detection of breast cancer.
