Evaluation of a histogenetic classification for XXXX .

@entity1 @entity704 @entity5 @entity1737 @entity6732
We reviewed 87 @entity5 from Chinese @entity1 and typed them according to the Marino and M  ller-Hermelink classification as updated by Kirschner and M  ller-Hermelink in 1989. Related categories were grouped for statistical analyses: group 1, @entity704 and @entity704 ; group 2, cortical predominant @entity704 ; group 3, @entity704 and @entity704 ; group 4, other @entity704 ; and group 5, unclassified. Group 3 @entity5 were more frequently associated with the @entity1737 compared with group 1 @entity5 (P = 0.001). They also presented at a more advanced stage. Groups 1 and 2 showed an excellent prognosis (100% survival at 10 years). The 10-year survival for groups 3 and 4 @entity1 was 40% and 30% respectively. Pure @entity704 made up a higher proportion of our cases (10.3%) than those of a similar Caucasian study (5.3%). The eight @entity704 (group 4) included two @entity6732 . We conclude that the histogenetic classification evaluated shows a clear correlation with prognosis and clinical features, even when tested on separate geographic groups, where pathogenetic factors may be different. A common approach to classification of @entity5 would greatly facilitate future studies on these possible differences.
