Development and Feasibility of a Community-Based,Culturally Flexible Colorectal Cancer Prevention Program

Comprehensive cancer centers are an important community resource for cancer prevention education in their catchment areas. Colorectal cancer remains one of the most commonly diagnosed cancers in the United States, making prevention a priority. Colorectal cancer prevention targets include lifestyle modifications that are influenced by cultural norms, such as diet change, physical activity and screening behavior. Cancer centers must tailor prevention efforts to multiethnic catchment areas. This paper describes the development and feasibility of a comprehensive cancer center’s approach to community-based colorectal cancer prevention in Houston, Texas, specifically targeting Hispanic and Asian populations. Sites were recruited through a city-wide network of partnerships between the community relations department in the hospital and community organizations. The program consisted of three workshop-style classes per community site. Each class had a similar overall structure, but cultural and site-specific adaptations were made for each group. A total of 33 classes were taught at nine distinct community sites to 1054 participants over 9 months. This program structure may be adapted for the future dissemination of other cancer prevention tools to communities in the area.
