The results of 3000 Fit: A prospective study led at Saint Joseph University of Beirut.
e15141 Background: In terms of frequency, colorectal cancer (CRC) is the 3rd cancer in Lebanon with 1093 incidences registered in 2015. To this date not a single screening campaign has been organized in the country. Fecal immunochemical test (FIT) is an advised screening technique. We found it useful to organize a screening campaign using FIT to determine the prevalence of CRC in a population of 3000 healthy Lebanese allowing the extraction of useful data. Methods: 3000 tubes were distributed to Lebanese adults (45-80 years old) at average risk of developing CRC, followed by explanations. FIT analysis was done at the medical genetics unit (UGM) of Saint-Joseph University and patients with positive FIT were asked to undergo further investigations. Results: Out of the 3000 distributed tests, 705 were returned (23.5%) with 459 fully analyzable. The age median was 56 (45-80). Sex ratio F/M 2.3. Out of the 459 patients, 278 (60.5%) showed 0ng/ml, 137 (29.8%) showed 1-79ng/ml, 3 (0.6%) showed 80-99ng/ml (intermediate risk values), 33 (7.1%) showed 100-800ng/ml considered as a positive value and finally 8 (1.7%) showed over range values. Among the 44 positive patients we contacted 41. Out of the 8 (18%) colonoscopies results received: 5 showed hemorrhoids leading to false positive, 1 ulcerative ileitis, 1 tubular adenomas and 1 carcinoma. Conclusions: While it was hard for us to quantify people for whom a free FIT was proposed, the low restitution rate among those who took the test shows the necessity of national screening and sensitization campaigns.
