Gastric Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - General Information About Gastric Cancer
Prognosis and Survival
The prognosis of patients with gastric cancer is related to tumor extent and includes both nodal involvement and direct tumor extension beyond the gastric wall.[8,9] Tumor grade may also provide some prognostic information.
In localized distal gastric cancer, more than 50% of patients can be cured. However, early-stage disease accounts for only 10% to 20% of all cases diagnosed in the United States. The remaining patients present with metastatic disease in either regional or distant sites. The overall survival rate in these patients at 5 years ranges from almost no survival for patients with disseminated disease to almost 50% survival for patients with localized distal gastric cancers confined to resectable regional disease. Even with apparent localized disease, the 5-year survival rate of patients with proximal gastric cancer is only 10% to 15%. Although the treatment of patients with disseminated gastric cancer may result in palliation of symptoms and some prolongation of survival, long remissions are uncommon.
Gastrointestinal stromal tumors occur most commonly in the stomach. (Refer to the PDQ summary on Gastrointestinal Stromal Tumors Treatment for more information.)
