Risk of subsequent primary cancers in patients with carcinoma of the Ampulla of Vater

Data were collected on subsequent primary cancers occurring in 194 individuals diagnosed with ampullary carcinoma during 1979-92 in the north western region of England, UK. Four cancers were identified compared with 6.62 expected (relative risk 0.60), suggesting that individuals with ampullary carcinoma are not at increased risk of developing subsequent primary cancers.
