Oral cancer after surgery for peptic ulcer

Abstract

Oral cancer was studied in a population of 3435 which constituted all persons who were operated upon because of peptic ulcer in Gothenburg 1952-61. This population formed a data base which was coordinated with the National Cancer Register and the Register of Causes of Deaths in Sweden. The expected number of oral cancers was 7.7 and the observed number was 17 (P < 0.01). In gerontologic population studies of the elderly in Gothenburg it was shown that 70-yr-old men with a history of peptic ulcer surgery more often were tobacco smokers, edentulous and more often had sideropenic and megaloblastic anemia and also had a lower bone mineral content.
