Review Meta Analysis Comparative Study
Systematic review and meta-analysis of the effectiveness and safety of extended lymphadenectomy in patients with resectable gastric cancer.
The extent of lymphadenectomy in the treatment of gastric cancer has been debated for more than two decades. This meta-analysis sought to evaluate the effectiveness and safety of extended lymphadenectomy in patients with gastric cancer. ⋯ D2 dissection was associated with a significantly higher postoperative risk. A trend towards lower gastric cancer-related mortality was found following D2 dissection that did not include resection of the spleen or pancreas, but further long-term survival data are needed to determine whether there is a specific survival benefit after D2 dissection.
