[Incidence of cancers and socio-professional status: data from the Bas-Rhin tumor Registry from 1975 to 1979]. / Incidence des cancers et statut socio-professionnel: données du Registre des tumeurs du Bas-Rhin de 1975 à 1979.

ABSTRACT

Data recorded in the Bas-Rhin cancer registry from 1975 to 1979 were used for studying the relationship between the incidence of some categories of cancer and social class. The relative risks associated with specific standardized incidence ratio (SIOR) of each cancer and social class were measured. Most of the results do not differ from other studies in developed countries. This study shows a positive gradient for colorectal cancers (SIOR = 58.4 in the lower class, 144.5 (non significant) in the upper class) and a negative gradient for cancers of the upper respiratory tract (SIOR = 51.5 in the upper class, 140.9 in the lower class). Urinary cancers (kidney, bladder) are not distributed as usual (SIOR = 201.5 in the upper class, 63.6 in the lower class). The validity of the measurement indices (SIR, SIOR, SPIR) is discussed.
