International collaboration between Japan and Chile to improve detection rates in XXXX screening.

BACKGROUND: In Chile, mortality from @entity14 ( @entity14 ) has increased rapidly. To help address this issue, the Prevention Project for @entity5 of the Colon and Rectum (PRENEC) program was initiated in 2012 with intensive support from @entity910 ( @entity910 ) in Tokyo, Japan, as part of an international collaboration. METHODS: From June 2012 to July 2014, a total of 10,575 asymptomatic @entity1 were enrolled in PRENEC. @entity1 with positive immunochemical fecal occult blood test (iFOBT) results or a family history of @entity14 underwent colonoscopy. The colonoscopy results from a similar, previous project in Chile (PREVICOLON) were compared with those from PRENEC. Furthermore, the initial colonoscopies of 1562 @entity1 in PRENEC were analyzed according to whether the colonoscopists were from @entity910 or Chile. RESULTS: The complete colonoscopy, @entity652 , and @entity5 detection rates were 88.0%, 26.7%, and 1.1%, respectively, in PREVICOLON, while the corresponding values were 94.4%, 41.8%, and 6.0%, respectively, in PRENEC. In PRENEC, 107 cases of @entity14 were detected, amounting for 1.0% of all @entity1 . Considering initial colonoscopies in PRENEC, the complete colonoscopy, @entity652 , and @entity5 detection rates were 97.4%, 45.3%, and 9.3%, respectively, for physicians at @entity910 and 93.3%, 41.5%, and 5.1%, respectively for Chilean physicians. The detection rates of @entity5 were 7.3% and 3.7%, respectively, for @entity910 and Chilean physicians. CONCLUSIONS: Quality indicators of colonoscopy substantially improved from PREVICOLON to PRENEC. The assessments made by Chilean physicians alone were improved in PRENEC, but remained better in the @entity910 group. Moreover, physicians from @entity910 detected more CRCs than Chilean physicians, especially at earlier stages. @entity5 2015.    2015 American @entity5 Society.
