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