    Abstract:
    BACKGROUND: The survival benefit associated with distal pancreatectomy with en bloc celiac axis resection (DP-CAR) for patients with borderline resectable or locally advanced pancreatic body carcinoma is controversial. The aim of this study was to evaluate the impact of DP-CAR following neoadjuvant chemotherapy on survival in patients with borderline resectable or locally advanced pancreatic body carcinoma. METHODS: Medical records of patients with pancreatic ductal adenocarcinoma who underwent distal pancreatectomy (DP, n = 102) and DP-CAR following neoadjuvant chemotherapy (n = 32) between 2008 and 2019 were analyzed retrospectively. Short- and long-term outcomes were compared between the two groups. RESULTS: All patients who underwent DP-CAR had tumor contact with the celiac axis. Of these, 30 patients underwent preoperative embolization of the common hepatic artery. The pretreatment tumor size of patients who underwent DP-CAR was larger (P < 0.001), and rates of blood transfusion (P = 0.003) and postoperative complications (P = 0.016) were higher in patients who underwent DP-CAR compared with patients who underwent DP. The 5-year survival rate of patients who underwent DP and DP-CAR were 50.6% and 41.1%, respectively (median survival time, 65.9 vs 37.0 months). For all 134 patients, pretreatment serum CA19-9 levels (P < 0.001), adjuvant chemotherapy (P < 0.001), and lymph node status (P = 0.035) were independent prognostic factors of overall survival by multivariate analysis. CONCLUSIONS: DP-CAR following neoadjuvant chemotherapy for patients with borderline resectable or locally advanced pancreatic body carcinoma may bring the same survival impact as DP, despite increased morbidity.
