Summary Gastric cancer is one of the leading causes of cancer-related death worldwide. Many patients have inoperable disease at diagnosis or have recurrent disease after resection with curative ...intent. Gastric cancer is separated anatomically into true gastric adenocarcinomas and gastro-oesophageal-junction adenocarcinomas, and histologically into diffuse and intestinal types. Gastric cancer should be treated by teams of experts from different disciplines. Surgery is the only curative treatment. For locally advanced disease, adjuvant or neoadjuvant therapy is usually implemented in combination with surgery. In metastatic disease, outcomes are poor, with median survival being around 1 year. Targeted therapies, such as trastuzumab, an antibody against HER2 (also known as ERBB2), and the VEGFR-2 antibody ramucirumab, have been introduced. In this Seminar, we present an update of the causes, classification, diagnosis, and treatment of gastric cancer.
Summary Background Postoperative pancreatic fistula is the leading cause of death and morbidity after pancreaticoduodenectomy. However, the best reconstruction method to reduce occurrence of fistula ...is debated. We did a multicentre, randomised superiority trial to compare the outcomes of different reconstructive techniques in patients undergoing pancreaticoduodenectomy for pancreatic or periampullary tumours. Methods Patients aged 18–85 years with confirmed or suspected neoplasms of the pancreas, distal bile duct, ampulla vateri, duodenum, or periampullary tumours were eligible for inclusion. An internet-based platform was used to randomly assign patients to either pancreaticojejunostomy or pancreaticogastrostomy as reconstruction after pancreaticoduodenectomy, using permuted blocks with six patients per block. Within each centre the randomisation was stratified on the pancreatic duct diameter (≤3 mm vs >3 mm) measured at the time of surgery. The primary endpoint was the occurrence of clinical postoperative pancreatic fistula (grade B or C) as defined by the International Study Group on Pancreatic Fistula. The study was not masked and analyses were done by intention to treat. Patient follow-up was closed 2 months after discharge from the hospital. This study is registered with ClinicalTrials.gov , number NCT00830778. Findings Between June, 2009, and August, 2012, we randomly allocated 167 patients to receive pancreaticojejunostomy and 162 to receive pancreaticogastrostomy. 33 (19·8%) patients in the pancreaticojejunostomy group and 13 (8·0%) in the pancreaticogastrostomy group had clinical postoperative pancreatic fistula (OR 2·86, 95% CI 1·38–6·17; p=0·002). The overall incidence of postoperative complications did not differ significantly between the groups (99 in the pancreaticojejunostomy group vs 100 in the pancreaticogastrostomy group), although more events in the pancreaticojejunostomy group were of grade ≥3a than in the pancreaticogastrostomy group (39 vs 35). Interpretation In patients undergoing pancreaticoduodenectomy for pancreatic head or periampullary tumours, pancreaticogastrostomy is more efficient than pancreaticojejunostomy in reducing the incidence of postoperative pancreatic fistula.
