Clinical pathway for the management of resectable gastric cancer with peritoneal seeding: best palliation with a ray of hope for cure.

Author information

Washington Cancer Institute, Washington, DC 20010, USA.


Peritoneal seeding from primary gastric cancer occurs in 10-20% of patients. The diagnosis of this advanced disease is usually not provided by clinical studies prior to abdominal exploration. From the data available in the literature, the surgeon is forced to make an intraoperative judgement concerning the risks and benefits of an aggressive management plan versus supportive care. A strategy has evolved that utilizes peritonectomy and extended gastrectomy to maximally cytoreduce tumor combined with perioperative intraperitoneal chemotherapy. In the current state of the art, the perioperative intraperitoneal chemotherapy is heated and manually distributed to provide uniform treatment to all peritoneal surfaces and the resection site. The pharmacologic parameters have been established and the results of phase II studies are reported. Five-year survival of patients in whom a complete cytoreduction was possible is approximately 10% with a median survival of 12 months. Gastrectomy with peritonectomy to eliminate all visible implants combined with perioperative intraperitoneal chemotherapy should be used in selected patients with primary gastric cancer and carcinomatosis.
