Double iFOB Test and Single iFOB Test Positive for Colorectal Cancer Screening:An Experience in Songkhla Province, Thailand
Keywords:
Colorectal cancer screening, immunochemical fecal occult blood, fecal immunochemical test, reducing burden of colonoscopyAbstract
Objective: This study was aimed to determine single and double immunochemical fecal occult blood test (iFOB) positive rate, prevalence of colorectal cancer (CRC) in average risk individuals (ARIs), burden colonoscopy, and identifying constraints for implementing CRC screening.
Methods: This study was a cross-sectional design. The targeted population was ARI aged between 50-70 years old. Two areas, in Songkhla province, were randomly selected. Fecal immunochemical test (FIT) and colonoscopy were used as screence and diagnostic tests. In Hat Yai, participant received one iFOB test and colonoscopy was indicated for those with a positive FIT. In Na Mom, 1-3 iFOB were provided to each individual and colonoscopy was indicated for the participant with double FIT positive. The study proposal was approved by the Hatyai Hospital Ethical Committee (ID 11 (25/03/2015)) and proper treatments were provided to all CRC suspected case.
Results: In Hat Yai, 883 participants were recruited and FIT positive was 274 (31.03%) whereas 94 (34.31%) received colonoscopy. We found that 8 (9.06%), 1(1.13%), and 2 (2.27%) were small adenoma, advanced adenoma, and colon cancer. In Na Mom, 930 participants were enrolled. Only 13 (1.40%) participants were double FIT positive and 10 (76.92%) received colonoscopy. The results showed that 3 (30.00%), 2 (20.00%), and 2 (20.00%) were small adenoma, advanced adenoma, and colon cancer. CRC detection rate was 2.20/1,000 ARIs.
Conclusion: This study demonstrated superior colonoscopy participation rate for double FIT positive compared to single FIT positive. Double FIT positive screening strongly preferred over single FIT positive. It abruptly reduced colonoscopy invitee and similar CRC detection rate is reported.
