[Correlation of histological classifications of XXXX with location and prognosis].

@entity1 @entity5 @entity189 @entity3 @entity356
AIM: To evaluate the prognostic impact of different histological classifications of @entity356 . METHODS: Between 1993-2000, 94 @entity1 with @entity356 were studied. @entity5 were classified according to TNM staging, WHO, Lauren and Goseki classifications. Twenty five @entity1 (27%) had a proximal @entity5 and 69 (73%) a @entity5 . Intestinal type according to Lauren were more often observed among the proximal @entity189 (19/25) than in distal ones (32/69) (P=0.01). According to Goseki, lymph node @entity3 were less frequently found in group III (5/13) than in other groups (64/81) (P=0.033). The mean follow-up was 23 months. Survical was not influenced by WHO, Lauren, and Goseki classifications. Survival significantly varied according to the different groups of the TNM classification. The proximal location of the @entity5 was associated with poorer prognosis than distal location (P=0.0373). Number of metastatic lymph nodes, invasion of perineurium, and vascular invasion had significant prognostic @entity189 . CONCLUSION: The results of this study suggest that @entity356 should be divided into proximal and @entity5 using the Goseki classification in addition to the Lauren classification because the Goseki classification recognizes @entity5 groups with different dissemination routes.
