Abstract

OBJECTIVES:

To evaluate the geographic variation of prostate cancer incidence in Connecticut during a 15-year period: before the introduction of prostate-specific antigen (PSA) testing (1984 to 1988), during its introduction (1989 to 1993), and after its widespread adoption (1994 to 1998).

METHODS:

A spatial scan statistic was used to detect and test the significance of the geographic rate variation among 29,944 incident cases.

RESULTS:

During 1984 to 1988, eight locations had incidence rates that differed significantly from the statewide level; for 1989 to 1993, only two locations were identified. By 1994 to 1998, a significant rate variation was noted for 10 locations around Connecticut.

CONCLUSIONS:

The observed geographic variation of incidence rates may reflect differing opportunities to uncover latent cases at given locales.
