Pancreaticoduodenectomy for locally advanced gastric cancer: Results from a pooled analysis.
Little is known about the clinical outcome of pancreaticoduodenectomy (PD) for locally advanced gastric cancer invading the duodenum and/or pancreas. The aim of this study was to define the clinical outcome and prognostic determinants of PD for locally advanced gastric cancer through a systematic review and pooled analysis of relevant data in the literature. A total of 13 articles involving 69 patients were eligible for inclusion. Postoperative morbidity and mortality were 59.4% and 1.4%, respectively. Overall 5-year survival and median survival were 39.3% and 26 months, respectively. Positive peritoneal lavage cytology represented the only independent prognostic factor for the poor outcome at multivariate analysis (hazard ratio 3.470, 95% confidence interval 1.011-11.909; P = 0.048). In summary, PD is a feasible option for locally advanced gastric cancer invading the duodenum and/or pancreas with an acceptable operative risk and offers survival benefits in selected patients.
