Purpose
Gastric cancer after pancreaticoduodenectomy was firstly reported in 1995, and the number of reports about this topic has increased in the past years. This review aimed to elucidate the clinicopathological features of this disease.
Methods
Data for 32 cases were obtained using literature search, and three cases in our institution were added.
Results
Twenty cases were reported from Japan, and fifteen cases were from the Western countries (Germany: 1 case, France: 2 cases, USA: 12 cases). In Japanese and the Western cases, the most dominant indication for pancreaticoduodenectomy was distal bile duct cancer and pancreatic ductal adenocarcinoma, respectively. The most frequently applied procedure of pancreaticoduodenectomy was pylorus-preserving pancreatoduodenectomy with pancreaticogastrostomy and pancreaticoduodenectomy with pancreaticojejunostomy, respectively. The median length of time interval from pancreaticoduodenectomy to GC detection tended to be shorter in the Japanese cases (61.5 months vs. 115 months). Of all cases, thirteen (37.1%) patients with gastric cancer showed no abdominal symptoms, and eight were diagnosed at regular gastroscopy. Surgical gastrectomy was performed in 30 patients, and among them, concomitant pancreatectomy was performed in six patients. Four patients received reanastomosis of remnant pancreas using pancreaticojejunostomy. Twenty-two (73.3%) patients had undifferentiated carcinomas, and stage 1, 2, 3, and 4 cancer was identified in 14, six, six, and four patients, respectively. All eight patients who had received routine gastroscopy were T1N0M0 stage 1.
Conclusion
Gastric cancers after pancreaticoduodenectomy including newly reported Japanese cases and our institutional cases were reviewed to make Japanese studies available to a broader scientific audience. Further investigation is necessary to elucidate the most important carcinogens among the various potential local and systemic factors.
