OBJECTIVE: To investigate the clinical phenotypes of @entity14 ( @entity14 ) in Chinese population. METHODS: Data of 34 @entity14 families diagnosed according to Armsterdam II Criteria and Japan Criteria, including age of diagnosis, site of @entity5 , history of synchronous and/or metachronous @entity14 , histopathology of @entity5 , clinical manifestations, and genealogy were collected and analyzed. RESULTS: Out of the 612 members aged over 18 of these 34 families 140 @entity1 were diagnosed as @entity14 @entity1 with 154 @entity5 foci, 93 males and 47 females. The median age of confirmed diagnosis of @entity14 was 45.3 years. 62.1% of them developed the @entity5 before the age of 50 and 87.1% of them developed the @entity5 before the age of 60. Out of the 154 primary @entity5 foci, 31 were extracolonic (20.1%), including @entity5 , with @entity356 accounting for 41.9% (13/31), and 123 were @entity694 (79.9%). Out of the 116 cases of @entity14 , there were 77 cases of proximal @entity694 (66.4%) and 39 cases of distal @entity694 (33.7%). There were 11 cases of @entity5 (7.86%). The main clinical manifestations included @entity360 , @entity417 , abdominal mass, and @entity490 . CONCLUSION: In comparison with the facts among Westerners, @entity14 occurred earlier; the proportions of proximal @entity694 , @entity5 , and @entity5 are larger; and @entity356 accounts for a greater percentage among Chinese.
