Feasibility of pre-operative chemoradiotherapy with gemcitabine to treat pancreatic cancer in patients with impaired renal function

Abstract

Objective: Although pre-operative chemoradiotherapy appears to be a promising treatment for patients with pancreatic ductal adenocarcinoma, there have been no reports of the feasibility of preoperative chemoradiotherapy in pancreatic ductal adenocarcinoma patients with renal impairment. The aim of this study was to evaluate retrospectively the feasibility of pre-operative chemoradiotherapy in pancreatic ductal adenocarcinoma patients with renal impairment. Methods: Twelve patients with resectable pancreatic ductal adenocarcinoma and a creatinine clearance of <60 ml/min were enrolled in this study. Gemcitabine-based pre-operative chemoradiotherapy was performed, followed by surgery. The feasibility of the treatment was evaluated in terms of clinical outcome and adverse events in the patients. Results: All 12 patients completed gemcitabine-based pre-operative chemoradiotherapy without worsening of renal function. Restaging after the therapy revealed radiologically unresectable disease in two patients. Among the remaining 10 patients who underwent laparotomy, curative resection was performed in eight patients. After curative resection, five patients out of the eight completed post-operative adjuvant therapy. The 1-and 3-year survival rates after the start of chemoradiotherapy in the 12 patients were 80.8 and 36.9%, respectively. Conclusions: Our findings suggest that gemcitabine-based pre-operative chemoradiotherapy may be a safe and effective treatment for pancreatic ductal adenocarcinoma in patients with renal impairment.
