Pancreaticoduodenectomy for gastric cancer

Abstract

Pancreaticoduodenectomy (PD) is performed to achieve an R0 resection for gastric cancer with pancreatic and/or duodenal invasion. Several retrospective case series have been published, but the sample cohorts in each study were heterogeneous and small. Moreover, the absence of prospective studies results in a lack of solid evidence that will help determine who can benefit from this procedure. Although the morbidity and mortality of PD have been reported by most studies to be acceptable and that the procedure is feasible, these remained to be much higher than those of standard gastrectomy. Therefore, careful selection of patients should be considered. Based on a review of previous case series and our own experience, PD appears to be beneficial to patients with gastric cancer with pancreatic invasion when R0 resection is possible. In addition, multidisciplinary treatment such as neoadjuvant chemotherapy, is anticipated to improve survival. Nevertheless, considering that prospective randomized studies are difficult to perform, a large-scale multicenter retrospective cohort study is required to evaluate this highly invasive procedure.
