Stomach cancer patterns in European immigrants to Connecticut, United States.
Age-adjusted annual incidence rates of stomach cancer (ICD-9 code #151) were examined for the period 1973-88 among Connecticut residents who were born in the United States or who emigrated from one of five European nations (Italy, Poland, the United Kingdom, Germany, Portugal). Risk of stomach cancer among each of the five immigrant groups was elevated significantly above that of US-born residents. The magnitude of difference ranged from a 1.62-fold excess among persons born in Italy to a 4.27-fold increase in risk among persons born in Portugal. Cancer risk to foreign-born residents was less than that observed in their native countries, with decreases of 25-64 percent found here. Several differences in patient and disease characteristics were observed according to country of birth. Compared with US-born residents, there was a lesser predominance of males among patients born in Italy, Poland, and the UK. Among all foreign-born groups, the gastric cardia was involved less frequently, and the pyloric region more frequently, than in US-born patients. Adenocarcinomas were significantly less common among Polish-born cases. The findings suggest different etiologies in foreign and US-born patients.
