BACKGROUND: The efficacy of portal vein resection for @entity788 is controversial. METHODS: Eighty-one consecutive @entity1 with @entity788 undergoing surgical resection were retrospectively analyzed. The clinicopathological findings and relationship between portal vein resection and survival were investigated. RESULTS: Thirty-three @entity1 with @entity788 underwent pancreatic resection with portal vein resection. Histological examination revealed that 17 @entity1 had definite invasion to the portal vein (group 1) and 16 @entity1 had no invasion (group 2). Forty-eight @entity1 with @entity788 underwent pancreatic resection without portal vein resection (group 3). There were no significant differences in survival rates (P = 0.437) between @entity1 with portal vein resection and @entity1 without portal vein resection. However, @entity1 in group 1 had a significantly (P = 0.021) worse prognosis as compared with those in group 2. Despite aggressive surgical resection, the surgical margin was positive in 35% of @entity1 in group 1 as compared with 13% of @entity1 in group 2 and 21% of @entity1 in group 3. CONCLUSIONS: @entity1 undergoing portal vein resection for @entity788 had a prognosis similar to @entity1 without portal vein resection. Negative microscopic invasion to the portal vein was significantly associated with improved survival.
