Brief summary

Colorectal cancer (CRC) is the second leading cause of cancer death in the United States and affects men and women almost equally. The United States Preventative Services Task Force (USPSTF) currently recommends screening with any of three options, which include fecal testing, flexible sigmoidoscopy, or colonoscopy. Screening for CRC with fecal occult blood testing (using a guaiac-based test) done annually or biennially has been shown to decrease mortality 15-33% primarily through detection of early stage cancer. Guaiac fecal occult blood testing (gFOBT) has a known positive balance of benefit and risk in screening populations, is the least expensive, and is the preferred method of screening in 30-55% of patients. The fecal immunochemical test (FIT) offers significant improvements over the gFOBT, most notably that it is easier to use (requires fewer samples and no dietary or medication restrictions) and is more sensitive than the gFOBT with respect to detecting both CRC and precancerous adenomas. As a result of improved test performance and usability, in 2008 multiple professional societies endorsed the use of four types of FITs for colorectal cancer screening. Kaiser Permanente currently uses the OC-Micro FIT as the fecal screening test in all regions. In recent years, intensive efforts have been undertaken to identify blood-based markers that may provide a promising alternative or supplement to fecal testing for non-invasive CRC screening. One method under development is to identify aberrantly methylated genes in cancer tissue through a blood test. Prior studies have explored those specific colorectal cancer genes that show the highest differences in methylation between the cancer and background genetic expression. Of these, methylation of the Septin 9 gene through a qPCR assay is relatively well studied. The proposed study aims to evaluate whether the Septin 9 biomarker may be used to supplement the OC-Micro FIT for colorectal cancer screening in such a way as to safely reduce unneeded colonoscopies. The population of interest for this study-those with a positive screening OC-Micro fecal immunochemical test-has a CRC prevalence of approximately 5%. Knowing how well Septin 9 can identify those without cancer prior to colonoscopy is important largely because colonoscopy, even when done diagnostically (e.g., after a positive FIT result), can cause serious complications.
