title: [Treatment strategy for marginally resectable gastric cancer].
abstract: It has been postulated that preoperative chemotherapy might promote tumor regression, eradicate nodal metastases, and improve resectability in patients with marginally resectable gastric cancer.For a marginally resectable tumor of gastric cancer, we selected the advanced gastric cancer patients with metastases and recurrences to the abdominal para-aortic lymph node (PAN), liver and invasion to the pancreas head and/or the duodenum.Patients with positive peritoneal cytology(P0, CY1)or localized peritoneal metastasis(P1), and Stage IV gastric cancer patients, were also considered candidates in this category. The strategy and results of surgical treatment for marginally resectable gastric cancer were explained as the dissection of PAN, hepatic resection, pancreaticoduodenectomy, perioperative chemotherapy for P0CY1 or P1, and neoadjuvant chemotherapy for Stage IV gastric cancer, which was still considered an experimental approach, although its use may be justified in unresectable or marginally resectable GC.The result of the resection of a marginally resectable gastric cancer is poor, but when there are no other non-curative factors, extended surgical resection should be performed because complete response is difficult at present with chemotherapy alone.In conclusion, there was no evidence suggesting that extended surgical procedures are effective, but a strategy of multidisciplinary treatment including extended surgical approach should be verified based on randomized controlled trials.
