Abstract
INTRODUCTION: The benefit of pancreaticoduodenectomy (PD) with superior mesenteric-portal vein resection (PVR) for pancreatic adenocarcinoma (PA) is still controversial in terms of morbidity, mortality and survival. We conducted a retrospective study to analyze outcomes of PD with PVR in a Spanish tertiary centre. METHODS: Between 2002 and 2012, 10 patients underwent PVR (PVR+ group) and 68 standard PD (PVR- group). Morbidity, mortality, overall survival (OS) and disease-free survival (DFS) were compared between PVR+ and PVR- group. Prognostic factors were identified by a Cox regression model. RESULTS: Postoperative mortality was 5% (4/78), all patients in PVR- group. Morbidity was higher in the PVR- group compared to PVR+ (63 vs. 30%, P=.004). OS at 3 and 5 years was 43 and 43% in PVR+ group, 35 and 29% in PVR- group (P=.07). DFS at 3 and 5 years DFS were 28 and 15% in PVR+ group, 25 and 20% in PVR- group (P=.84). Median survival was 23.1 months in PVR- group, and 22.8 months in PVR+ group (P=.73). Factors related with OS were absence of adjuvant treatment (OR 2.9, 95%IC: 1.39-6.14, P=.003), R1 resection (OR 2.3, 95%IC: 1.2-4.43, P=.006), preoperative CA 19.9 level ≥ 170 UI/mL (OR 2.3, 95%IC: 1.22-4.32, P=.01). DFS risk factors were R1 resection (OR 2.6, 95%IC: 1.41-4.95, P=.002); moderate or poor tumor differentiation grade (OR 2.7, 95%IC: 1.23-6.17, P=.01); N1 lymph node status (OR 1.8, 95%IC: 1.02-3.19, P=.04); CA 19.9 level ≥ 170 UI/mL (OR 2.4, 95%IC: 1.30-4.54, P=.005). CONCLUSIONS: PVR for PA can be performed safely. Patients with PVR have a comparable survival to patients undergoing standard PD if disease-free margins can be obtained.
