Answer

The rates of gastric cancer are higher in Asian and South American countries than in the United States; in Japan, for example, stomach cancer is the most common cancer site in males. [5]  Japan, Chile, and Venezuela have developed a very rigorous early screening program that detects patients with early-stage disease (ie, low tumor burden). These patients appear to do quite well. In fact, in many Asian studies, patients with resected stage II and III disease tend to have better outcomes than similarly staged patients treated in Western countries. Some researchers suggest that this reflects a fundamental biologic difference in the disease as it manifests in Western countries.

In the United States, the incidence of stomach cancer in males is highest in blacks, followed by Asians and Pacific Islanders, Hispanics, and American Indian/Alaska natives. In females, rates are highest in Asians and Pacific Islanders, followed by blacks and Hispanics and American Indian/Alaska natives. In both males and females, rates are lowest in whites. [2]
