Abstract

Background

The prognostic impact of pancreatic ductal adenocarcinoma (PDAC) invasion to the splenic vessel is controversial.

Objective

The aim of this study was to assess the clinical value of pathological and radiological splenic vessel invasion in PDACs of the body and tail.

Methods

Medical records of patients with resectable PDAC of the body and tail who underwent distal pancreatectomy between 2003 and 2016 at the Kobe University Hospital were retrospectively analyzed.

Results

Overall, 68 patients (29 female and 39 male patients) were enrolled. Pathologically determined splenic vein invasion (p-SV) and splenic artery invasion (p-SA) were identified in 21 (30.9%) and 5 (7.4%) patients, respectively. The p-SV (but not p-SA) was an independent prognostic factor in multivariate analysis (p = 0.009). On analysis of recurrence patterns, patients with PDAC positive for p-SV were at a higher risk for liver metastasis (p = 0.022); however, the associations were not significant for other recurrence patterns. Liver metastasis occurred earlier in patients who were positive for p-SV (p = 0.015). Preoperative computed tomography effectively diagnosed pathological vessel invasion (SV: sensitivity, 95.2%, specificity, 72.3%; SA: sensitivity, 100%, specificity, 84.1%). Radiological SV invasion remained significant in multivariate analysis regarding postoperative survival (p = 0.007), and was also associated with early liver metastases (p = 0.008).

Conclusions

Pathological/radiological SV invasion were independent adverse prognostic factors associated with early liver metastasis in patients with PDAC of the body/tail. Assessment of these findings may be useful in determining optimal therapeutic options in these patients.
