OBJECTIVE: To evaluate the detection rates of @entity14 in the elderly and characterize the pathological features of the @entity14 in DongLi District in Tianjin. METHOD: Totally, 46 743 subjects aged 60-74 were recruited from the national @entity14 screening program, including subjects registered from November 2012 to April 2013 in DongLi District in Tianjin. Each subject completed a questionnaire and a fecal occult blood test. Colonoscopies were conducted in 434 subjects with high risk for @entity14 . RESULTS: Among all the subjects, 2 880 were at high risk for @entity14 which accounts for 6.16% (2 880/46 743) of the total subjects. Among the subjects who underwent the colonoscopy, 165 ( @entity1 : 105, @entity1 : 60) were @entity1127 for 5.73% (165/2 880) in the total risk, with 51 subjects (1.77%) advanced @entity5 and 4 subjects (0.14%) @entity5 . The detection rates of @entity1127 is 0.35% (165/46 743), and @entity14 is 8.6/10(5) (4/46 743). More @entity1127 were found on the left colon compared with the right. More tubular adenoma was found compared with the other pathological types. Most of the @entity1127 were smaller than 0.5 cm. @entity1127 were more frequent in @entity1 than @entity1 [45.45% (105/231) vs 29.56% (60/203), 16.02% (37/231) vs 6.90% (14/203), all P < 0.01]. @entity1127 (P < 0.05) and @entity1127 with diameter larger than 1.0 cm (P < 0.01) were more often in @entity1 than in @entity1 . @entity1 tended to have more @entity1586 and higher detection rate for moderate or sever atypical @entity1373 than @entity1 (all P < 0.05). CONCLUSION: There is a higher incidence of @entity1127 in the elderly. It is important to establish the national sequential @entity14 screening program for the early diagnoses of @entity14 in the elderly.
