@entity5 @entity14 @entity3 @entity2802
Hepatic @entity3 from @entity14 represent a serious complication, often at the origin of death. Very few studies allow to know their epidemiological characteristics. From available data the proportion of @entity14 with synchronous liver @entity3 is 15% and the 5 year cumulative risk of metachronous @entity3 is 16%. According to C  te-d'Or data, it was 4.6% for @entity2802 stage 1 @entity5 , 14.1% for stage 2 and 32.0% for stage 3. Taking into account incidence and prevalence of @entity14 it can be estimated that the number of synchronous hepatic @entity3 is 5,400 per year and the number of metachronous hepatic @entity3 9,000 per year. In the C  te-d'Or area 6.5% of synchronous hepatic @entity3 , were resected for cure and 21% of metachronous hepatic @entity3 . The survival rates for synchronous hepatic @entity3 were 31% at 1 year and 2% at 5 year. The corresponding rates for metachronous @entity3 were 31% and 4%. After surgery for cure the 5 year survival rate was 11% for synchronous @entity3 and 16% for metachronous @entity3 . Population based data indicates that liver @entity3 from @entity14 represent a frequent problem and are more frequent that suggested by hospital-based data.
