OBJECTIVE: To determine the incidence of @entity14 ( @entity14 ) in young Jordanians and to compare the clinical and pathological characteristics with those in older @entity1 and with those in high risk populations. METHODS: Clinical and pathological data of all the @entity1 with @entity14 managed at Princess Basma Teaching Hospital, Irbid, Jordan over a 10 year period (January 1990 through December 1999) were recorded. The @entity1 were divided according to age into group one (those <40 years) and group 2 (> 40 years). The 2 groups were compared regarding sex, predisposing conditions, @entity5 stage at presentation, @entity5 differentiation, @entity3558 secretion, @entity5 invasion, presentation with complications and @entity5 location. The data were compared with those of "high risk" Western populations and with the few reports coming from "low risk" populations, mainly from Kingdom of Saudi Arabia and Egypt. RESULTS: Out of 202 @entity1 evaluated, 4 were excluded. Group 1 constituted 20.2% of the @entity1 , 17.5% of them have predisposing conditions. Comparison between group 1 and 2 revealed the following: female sex (65% versus 50.6%, p=0.104), advanced stages at presentation (65% versus 41%, p=0.005), @entity5 (50% versus 39.2%) and right side @entity5 (15% versus 29.1%) (p=0.18). Mucinous and signet ring @entity5 (30% versus 15.8%, p=0.04), poor @entity5 differentiation (20% versus 18.3%, p=0.78) and presentation with complications (21% versus 22.2%, p=0.96). CONCLUSION: The incidence of @entity14 in young Jordanians was much higher than high risk populations. Half of the @entity5 were rectal. Young @entity1 have more advanced stage and more @entity3558 secreting @entity5 . The relative high frequency and frequency of predisposing conditions calls for family screening and surveillance in the presence of predisposing conditions.
