Abstract

Backgrounds: Distal pancreatectomy with en bloc celiac axis resection (DP-CAR) is an extended surgical procedure for patients with locally advanced cancer of the pancreatic body and tail. Recently, the usability of neoadjuvant chemotherapy (NAC) in pancreatic cancer was reported. The purpose of this study was to clarify the impact of NAC on surgical outcomes and prognosis in DP-CAR patients. Methods: This study retrospectively reviewed 20 consecutive patients who underwent DP-CAR at a single institution. Results: Eleven of 20 patients (55.0%) received NAC. Their first regimens were gemcitabine (GEM) plus nab-PTX (n = 7, 63.6%), GEM plus S-1 (n = 3, 27.3%), and GEM (n = 1, 9.1%). Although two patients converted to a second regimen, none abandoned NAC due to adverse effects or could not undergo a planned procedure for disease progression. There were no significant differences in intraoperative variables, morbidity, including pancreatic fistula and delayed gastric emptying, and mortality between patients with and without NAC; however, patients with NAC had a significantly lower proportion of arterial invasion (p = 0.025), lymphatic invasion (p < 0.0001), and vascular invasion (p = 0.035). There were no significant differences in the induction rate of adjuvant chemotherapy (p = 0.201). The recurrence-free survival and overall survival rates in patients with NAC were significantly higher than in patients without NAC (p = 0.041 and p = 0.018, respectively). Conclusion: DP-CAR following NAC was associated with a preferable prognosis and had no negative effect on surgical outcomes. Therefore, NAC in DP-CAR patients might be a beneficial and safe therapeutic strategy.
