OBJECTIVES: A retrospective study was performed to determine the prognostic implications of invasion to the splenic vessels in pancreatic body and tail cancer. SUMMARY BACKGROUND DATA: Involvement of the splenic artery (SA) and vein (SV) is frequently observed in carcinoma of the body and tail of the pancreas, but its correlation with various other clinicopathologic factors and prognosis has not been explored in detail. METHODS: Fifty-one patients who had undergone distal pancreatectomy for invasive adenocarcinoma of the body and tail of the pancreas were discreetly selected from the prospective data base for analyses. Cases that required extended surgery due to invasion of the major vessels such as the portal vein, common hepatic artery, celiac artery, and superior mesenteric artery were excluded. Correlation between invasion of the splenic vessels and prognosis and other clinicopathologic factors were analyzed. RESULTS: Seventeen patients with invasion of the SA had a significantly inferior prognosis compared with those without the invasion (P = 0.0067), whereas invasion of the SV, observed in 24 patients, did not affect prognosis. Additionally, invasion of the SA significantly correlated with tumor size > or = 2 cm, anterior serosal infiltration, perineural invasion and SV invasion (P = 0.0440, P = 0.0406, P = 0.0460, and P = 0.0173, respectively). In univariate analysis, SA invasion, lymph node metastasis, and anterior serosal infiltration were identified as significant poor prognostic factors. In multivariable analysis, only SA invasion was an independent prognostic factor (odds ratio, 2.611, P = 0.0196). CONCLUSIONS: Our results indicated that the invasion of the SA, but not that of the SV, is a crucial prognostic factor in pancreatic body and tail cancer.
