Abstract

Purpose: Preoperative chemoradiotherapy (CRT) can be a promising treatment for pancreatic ductal adenocarcinoma (PDAC). However, its administration for patients with impaired renal function has not been well investigated, let alone its clinical effect. We previously reported preliminary feasibility of CRT in PDAC patients with renal impairment. Herein, we aimed to investigate the clinical effects of preoperative CRT including safety and long-term prognosis in more PDAC patients with renal impairment as an extension to our previous work. Methods: This study enrolled twenty patients harboring resectable PDAC with creatinine clearance level less than 60 ml/min. Patients underwent preoperative CRT with gemcitabine, followed by surgery. The clinical effects of the therapy were evaluated in terms of safety and long-term prognosis. Results: Preoperative CRT was completed in all 20 patients. Grade 4 leukopenia/neutropenia was identified as an observed toxicity in four cases (20.0%). Renal function was not worsened after CRT. After CRT, 17 cases were judged resectable and underwent laparotomy. Pancreatic resection was performed in 15 of the 17 patients; it was not performed in two patients because of peritoneal dissemination. The 1-/3-/5-year cumulative survival rate from the initiation of CRT for the 20 patients was 88.8%/45.5%/22.8%. In the 15 patients, renal function was not worsened after surgery. Conclusion: Our findings suggest that the clinical effects of preoperative CRT would be favorable in PDAC patients with renal impairment.
