OBJECTIVE: To appraise the histological characteristics and clinical features of @entity356 ( @entity356 ) and their relevance with prognosis. METHODS: From January 2001 to December 2003, six @entity1 were diagnosed and confirmed pathologically in Ruijin Hospital as having a gastric @entity189 . All these six @entity1 , together with 30 randomly selected @entity1 with gastric poorly differentiated @entity420 (GPDA) and 30 with a primary @entity157 ( @entity157 ) who served as controls, were studied and analyzed clinically, histologically and immunohistologically. RESULTS: The average age of the six @entity1 with @entity356 was 66.8 years, and their serum @entity160 ( @entity160 ) level was 84-2230 ng/mL. Of these six @entity1 , two had a recurrence of @entity5 and two had liver @entity3 . Their average survival period was 17 months. Morphologically, the histological appearance was similar to that of @entity157 , with glycogen granules and hyaline globules arranged in a solid or trabecular pattern and an abundance of blood vessels and sinusoids, while blood vessel or lymphatic invasion were more often seen. Immunohistological staining showed that the @entity5 cells were positive for @entity160 and negative for Hepatocyte paraffin 1 (HepPar1), and the @entity5 cells were separated by @entity2280 -positive blood vessels into a small trabecular pattern. The GPDA had a solid nest or diffuse distribution pattern and was negative for both @entity160 and HepPar1. In the @entity157 , the histological feature was manifested as solid, small and large trabecular patterns with abundance of blood vessels and sinusoids; immunohistochemical staining showed the @entity5 cells were positive for HepPar1. CONCLUSION: Serum @entity160 -positive @entity356 occurred more frequently in older @entity1 with higher rates of recurrence and liver @entity3 and a poor prognosis. Histologically, @entity356 was similar to @entity157 . The @entity5 cells that were positive for @entity160 but negative for HerPar1 could be used to differentiate with GPDA (both @entity160 and HerPar1 negative) and primary @entity157 (most @entity160 and HerPar1 positive).
