ABSTRACT: BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is a deadly disease. Neoadjuvant therapy (NA) with chemotherapy (NAC) and radiotherapy (RT) prior to surgery provides promise. In the absence of prospective data, well annotated clinical data from high-volume units may provide pilot data for randomised trials. METHODS: Medical records from a tertiary hospital in Sydney, Australia, were analysed to identify all patients with resectable or borderline resectable PDAC. Data regarding treatment, toxicity and survival were collected. RESULTS: Between January 1 2010 and April 1 2016, 220 sequential patients were treated: 87 with NA and 133 with upfront operation (UO). Forty-three NA patients (52%) and 5 UO patients (4%) were borderline resectable at diagnosis. Twenty-four borderline patients received NA RT, 22 sequential to NAC. The median overall survival (OS) in the NA group was 25.9 months (mo); 95% CI (21.1-43.0 mo) compared to 26.9 mo (19.7, 32.7) in the UO; HR 0.89; log-ranked p-value = 0.58. Sixty-nine NA patients (79%) were resected, mOS was 29.2 mo (22.27, not reached (NR)). Twenty-two NA (31%) versus 22 UO (17%) were node negative at operation (N0). In those managed with NAC/RT the mOS was 29.0 mo (17.3, NR). There were no post-operative deaths with NA within 90-days and three in the UO arm. DISCUSSION: This is a hypothesis generating retrospective review of a selected real-world population in a high-throughput unit. Treatment with NA was well tolerated. The long observed survival in this group may be explained by lymph node sterilisation by NA, and the achievement of R0 resection in a greater proportion of patients.

ABSTRACT: BACKGROUND: Resection of the involved mesenteric-portal vein (MPV) is increasingly performed in pancreatoduodenectomy. The primary aim of this study is to assess the rate of R0 resection in transverse closure (TC) versus segmental resection with end-to-end (EE) closure and the secondary aims are to assess the short-term morbidity and long-term survival of TC versus EE. METHODS: Patients undergoing pancreatoduodenectomy with MPV resection were identified from a prospectively database. The reconstruction technique were examined and categorized. Clinical, pathological, short-term and long-term survival outcomes were compared between groups. RESULTS: 110 patients underwent PD with MPV resection of which reconstruction was performed with an end-to-end technique in 92 patients (84%) and transverse closure technique in 18 patients (16%). Patients undergoing transverse closure tended to have had a shorter segment of vein resected (≤2 cm) compared to the end-to-end (83% vs. 43%; P = 0.004) with no difference in R0 rate. Short-term morbidity was similar. The median and 5-year survival was 30.0 months and 18% respectively for patients undergoing transverse closure and 28.6 months and 7% respectively for patients undergoing end-to-end reconstruction (P = 0.766). CONCLUSION: Without compromising the R0 rate, transverse closure to reconstruct the mesenteric-portal vein is shown to be feasible and safe in the setting when a short segment of vein resection is required during pancreatoduodenectomy. Synopsis - We describe a vein closure technique, transverse closure, which avoids the need for a graft, or re-implantation of the splenic vein when resection of the mesenteric-portal vein confluence is required during pancreatoduodenectomy.
