title: Preoperative treatment and surgery in gastric cancer: friends or foes?
abstract: Until 2006, most reports of preoperative (neoadjuvant) treatments for gastric carcinoma were inconclusive and produced confusing results due to inhomogeneous treatment regimens, selection of patients, and response assessment. Since publication of the results from the MAGIC trial, substantial scientific evidence has suggested the benefits of perioperative (preoperative and postoperative) chemotherapy to locally advanced gastric cancer. To date, this phase III trial, coupled with preliminary data from other published reports on neoadjuvant chemotherapy and radiotherapy, supports the theoretical advantages of preoperative treatment for gastric carcinoma, thus introducing the concept of delayed surgery. Neoadjuvant treatment of resectable, locally advanced tumours might improve patients' outcomes and postpone the need for curative resection, but it also exposes patients to the risk of tumour progression.
