title: [Synchronous cancer duplicities of pancreas and stomach/kidney and their surgical treatment].
abstract: BACKGROUND
  The occurence of synchronous pancreatic cancer and other primary cancer is not frequent and reaches about 5.6% as reported in autoptic studies. Double resections of the pancreas with another organ due to synchronous malignancies have been published only in quite sporadic sets of cases or individual case reports. The authors present three cases of synchronous pancreatic malignancies and stomach or renal cancers treated with surgery, including results and survival.
  
  
  METHODS
  Three patients with synchronous double cancer were identified in a series of 400 pancreatic resections (20062014). Two patients presented with symptoms of pancreatic periampullary tumors (bile duct obstruction, weight loss and abdominal pain). The second malignancies were identified as incidental during diagnostic work-up (asymptomatic cancer of the stomach, kidney). Pancreatoduodenectomies (PDE) with lymphadenectomies were performed due to ductal adenocarcinomas (pT2N1M0 G3 and pT3N1M0 G2). The second procedures included subtotal gastrectomy with lymphadenectomy (gastric adenocarcinoma pT1N1M0, G2) and nephrectomy (renal papillary carcinoma pT1bN0M0, G3). Postoperative adjuvant chemotherapy with gemcitabine was given in both patients. Survival rates were 12 and 19 months, respectively. The third patient suffered from abdominal pain and weight loss. Diagnostic work-up revealed stomach carcinoma and early pancreatic adenocarcinoma. Double resection - subtotal gastrectomy with lymphadenectomy and pancreatoduodenectomy with lymphadenectomy - was performed. Gastric adenocarcinoma pT2N2M0, G3 and pancreatic ductal papillary-mucinous adenocarcinoma pT2N0M0, G1 were found in the specimens. Adjuvant radiochemotherapy with 5-fluorouracil and leukovorine was given postoperatively. This patient is still alive nearly 5 years after the surgery, without any reccurence.
  
  
  CONCLUSIONS
  The survival of patients with double synchronous pancreatic malignancies and other primary tumors in our set seems to be influenced by the stage and biology of pancreatic cancer. The survival was worse when the duplicity was presented with symptoms of pancreatic cancer. Pancreatic cancer found incidentally when another malignancy is presented has more favourable results.
