Influence of perioperative intraarterial selective chemotherapy on terms of recurrent ductal adenocarcinoma of the pancreatic head after pancreaticoduodenectomy

Abstract

Aim. To analyze influence of perioperative intra-arterial selective chemotherapy on terms of recurrent ductal adenocarcinoma of pancreatic head after pancreaticoduodenectomy.Material and methods. 111 patients underwent combined treatment. Surgical stage included conventional pylorussparing pancreaticoduodenectomy in all groups. The main group consisted of 52 patients who received combined treatment: neoadjuvant chemoembolization with gemcitabine (400 mg/m2) and oxaliplatin (50 mg/m2), surgical treatment and 6 courses of regional chemotherapy – infusion of gemcitabine (800 mg/m2) and oxaliplatin (45 mg/m2) into celiac trunk in adjuvant mode. The control group was presented by 59 patients who underwent perioperative regional chemotherapy (neoadjuvant chemoembolization and adjuvant infusion of gemcitabine (800 mg/m2). Progression-free survival (PFS) and terms of recurrence were analyzed in all groups. In case of progression and recurrence we applied regional chemotherapy alone. Systemic chemotherapy was not used in the study.Results. Annual PFS in the main and the control groups was 80%. Three-year PFS in the main group was 37%, in the control group – 14% (p < 0.01). Five-year PFS was 11% in the main group and absent in the control group. Median survival was 26 months in the main group and 22.6 months in the control group. Overall annual, 2-year and 5-year survival in main group was 80%, 57% and 15%, respectively.Conclusion. Regional intra-arterial chemotherapy decreases incidence of recurrences and improves PFS after surgical treatment of pancreatic head adenocarcinoma.Further multi-center studies are necessary to assess the effectiveness of regional chemotherapy.
