Abstract

PURPOSE:

Surgery followed by chemotherapy and radiation (CRT) offers patients with pancreatic adenocarcinoma a chance for extended survival. In some patients, however, resection is difficult because of vascular involvement by the carcinoma, necessitating resection and grafting of the mesenterico-portal vessels. The purpose of this study was to compare outcomes between pancreaticoduodenectomy (PD) with and without mesenterico-portal vein resection (VR) in patients receiving adjuvant CRT for pancreatic adenocarcinoma.

METHODS AND MATERIALS:

Between 1993 and 2005, 160 patients underwent PD with 5-FU-based adjuvant CRT followed by maintenance chemotherapy at the Johns Hopkins Hospital; 20 (12.5%) of the 160 underwent VR. Clinical outcomes, including median survival, overall survival, and complication rates were assessed for both groups.

RESULTS:

Patients who underwent VR had significantly longer operative times (p = 0.009), greater intraoperative blood loss (p = 0.01), and longer postoperative lengths of stay (p = 0.03). However, postoperative morbidity, median survival, and overall survival rates were similar between the two groups. Most patients (70%) from both groups were able to complete CRT, and a subgroup analysis demonstrated no appreciable differences in terms of complications. None of the VR patients who received adjuvant CRT developed veno-oclusive disease or graft failure/leakage.

CONCLUSION:

In a cohort of patients treated with adjuvant 5-FU-based CRT at the Johns Hopkins Hospital, having a VR at the time of PD resulted in similar complication rates and survival. These data support the feasibility and safety of adjuvant CRT in patients undergoing VR at the time of PD.
