MedicalResearch.com: What is the background for this study?
Response: Briefly, anal cancer makes up around 1% of gastrointestinal cancers and more than 90% of all anal cancers are caused by chronic human papillomavirus or HPV infections.
In previous research, it has been noted that women over the age of 65 have rates that were increasing more than other groups and myself along with my colleagues and the principal investigator of this project, Dr. Eli Ehrenpreis, wanted to further characterize these findings, looking into more specific details of these previously noted trends. Using data from a public database ran by the National Cancer Institute called the Surveillance, Epidemiology and End Results program, also known as SEER, and their statistical analysis software, SEER*Stat, we analyzed anal cancer incidence trends, looking at differences between sex, age, and ethnicity in order to further identify specific groups that have more rapidly increasing rates than others.

MedicalResearch.com: What is the background for this study?
Response: Kaiser Permanente Northern California (KPNC) is an integrated health care system that designs and implements population-based programs that support cancer prevention and early detection. In 2006, KPNC began to implement a comprehensive colorectal cancer screening program with the goal of increasing member screening rates, preventing colorectal cancer through polyp removal, and reducing cancer mortality. The initiative identifies whether screening-eligible KPNC members are up to date with their colorectal cancer screening test by either a colonoscopy or by stool-based tests, such as a fecal immunochemical testing (FIT) kit. If they are not up to date with screening, it mails them a FIT kit for at-home testing. Members can also choose other options for colorectal cancer screening, such as a colonoscopy, through their physician.

MedicalResearch.com: What is the background for this study?
Response: Colorectal cancer rates in young people under age 50 are skyrocketing and have been for the last 3-4 decades. We really don’t understand why because most cases (probably around 70%) are not genetic or hereditary, just random, unfortunate events. We suspect that it is some exposure(s) like excess consumption of red meat, processed foods, sugar-sweetened beverages, excess antibiotic use altering the microbiome, rising incidence of obesity or some other factors. We really don’t know why yet.
Our study used a technology called metabolomics, the study of breakdown products and production building blocks for our bodies, to look for differences in colorectal cancer in young people versus people that are older that developed colorectal cancer. Because metabolomics measures how each individual interacts with the exposures in our environment like diet, air quality, etc., it is a way to bridge the gap between our nature (determined by genetics) and nurture (determined by our exposures).

MedicalResearch.com: What is the background for this study?
Response: Early-onset colorectal cancer (EO-CRC, age <50 years at diagnosis) is rapidly rising in the US since the mid-1980s, with an unclear understanding of its etiology and contributors to the rise. Sugar-sweetened beverages (SSBs) exert adverse metabolic repercussions throughout the life course, including insulin resistance and inflammation. Higher SSB intake can induce obesity, which has been linked to risk of EO-CRC. A recent experimental study also suggests that high fructose corn syrup, a primary sweetener in SSBs, may promote colon tumor growth, independent of metabolic dysregulation. In the US, SSB consumption has dramatically increased during the 2nd half of the 20th century, and adolescents and young adults have been the heaviest SSB drinkers across all age groups. Thus, we expect SSBs may be an emerging risk factor for EO-CRC and likely contribute to the rising incidence of EO-CRC.
