Duodenal stenting followed by systemic chemotherapy for patients with pancreatic cancer and gastric outlet obstruction



Duodenal stenting followed by systemic chemotherapy for patients with pancreatic cancer and gastric outlet obstruction



Pancreatology 16(6): 1085-1091



Endoscopic duodenal stenting has recently been proposed as a substitute for surgical gastrojejunostomy for the treatment of gastric outlet obstruction. We aimed to evaluate the efficacy and safety of duodenal stenting followed by systemic chemotherapy for patients with advanced pancreatic cancer with gastric outlet obstruction. This was a single-center, retrospective cohort study, conducted at an academic medical center, of 71 patients with advanced pancreatic cancer and gastric outlet obstruction (mean age: 67.6 years; range: 31-92 years) who underwent duodenal stenting with or without subsequent chemotherapy. Overall survival, duration of oral intake of foods, the rate of introduction of chemotherapy, progression-free survival, and adverse events were evaluated. Stent placement was technically successful in 69 (97%) patients. Thirty-six (51%) patients were treated with chemotherapy: 17 with gemcitabine alone, 15 with S-1 alone, 3 with FOLFIRINOX, and 1 with paclitaxel. Median progression-free survival and overall survival after chemotherapy were 2.6 months (95% confidence interval: 1.3-3.9 months) and 4.7 months (95% confidence interval: 2.6-6.8 months), respectively. Cases of grade 3 anemia were frequently observed during chemotherapies following duodenal stenting (32%). Tumor stage, performance status, neutrophil-to-lymphocyte ratio, and introduction of chemotherapy were independent prognostic factors for survival (hazard ratios of 3.73, 2.21, 2.69, and 1.85 with p-values of <0.001, 0.010, <0.001, and 0.045, respectively). The findings of this study suggest that endoscopic duodenal stenting is an advantageous treatment in advanced pancreatic cancer patients with gastric outlet obstruction regarding its safety and smooth conduction of subsequent chemotherapies.
