Abstract

OBJECTIVES:

To determine the influence of neoadjuvant chemoradiation and standardized dissection of the superior mesenteric artery upon the oncologic outcome of patients with localized pancreatic adenocarcinoma.

METHODS:

One hundred ninety-four patients with pancreatic adenocarcinoma who underwent pancreaticoduodenectomy between 2004 and 2008 were evaluated. The retroperitoneal dissection was performed directly along the superior mesenteric artery in all cases. A standard histopathologic protocol that measured the "superior mesenteric artery (SMA) margin distance" between cancer cells and the superior mesenteric artery was employed.

RESULTS:

Seventy-six percent of patients received neoadjuvant chemoradiation. The SMA margin was positive in 4% of patients but an additional 22% of patients with a negative margin had a SMA margin distance of ≤1 mm. Preoperative CT images overestimated the SMA margin distance in 73% of cases. Patients who received chemoradiation had longer SMA margin distances than those who did not. Patients who received chemoradiation and had a SMA margin of >1 mm had the lowest recurrence rates. Administration of neoadjuvant chemoradiation and lower estimated blood loss were independently associated with longer progression-free survival on multivariate analysis.

CONCLUSIONS:

Preoperative chemoradiation and meticulous dissection of the superior mesenteric artery maximize the distance between cancer cells and the SMA margin and may influence locoregional control.
