Age differences in the breast cancer management of rural women.
This article describes the effect of age on the pattern of access to breast cancer care among rural women diagnosed in 1986-1989. Cases were identified by the Illinois State Cancer Registry and information on breast cancer management was obtained through review of hospital records and physician survey. Case follow-back was more than 99% complete. State-of-the-art breast cancer management was defined by the Physician Data Query (PDQ) and included diagnostic evaluation, prognostic evaluation, and stage-specific definitive treatment. The data did not indicate age differences in bilateral diagnostic mammography, performance of hormone receptor assays, radiation therapy, and stage-appropriate treatment. Tumor staging and axillary node dissection did differ by age with significant negative trends in the multivariate model. Also, women younger than 55 years were the most likely to receive separate diagnostic biopsy, limited surgery, and chemotherapy, whereas women 55 to 74 years were most likely to receive hormone therapy. Although rural populations may experience barriers to some aspects of state-of-the-art breast cancer management, age does not always exacerbate them.
