One in four colorectal cancer cases, detected through a guiac fecal occult blood testing program, are diagnosed within two years of a negative screening result, according to a study in the UEG Journal.
Here are five insights:
1. Around 772,790 people participated in the observational study.
2. The study subjects were asked to participate in guiac fecal occult blood testing screening over two years.
3. Of the 1,979 individuals who were diagnosed with CRC during the study period, 25 percent of the cases detected were within two years of a negative screening result.
4. The study suggests that guiac fecal occult blood testing should be replaced by more sensitive screening methods to improve detection rates.
5. The study suggests fecal immunochemical testing, which has been shown to help increase CRC detection.
