Surveillance and beliefs about follow-up care among long-term breast cancer survivors: a comparison of primary care and oncology providers

Delivery of follow-up care to breast cancer survivors is an important public health issue due to their increasing number and the anticipated shortage of oncology providers. this study evaluated adherence to american society of clinical oncology (asco)-recommended surveillance tests in a bi-ethnic cohort of long-term breast cancer survivors. women (n = 298) in arizona and colorado who had previously participated in a population-based study of breast cancer were enrolled into a follow-up survey approximately 6 years post-diagnosis. asco-recommended surveillance (mammogram, clinical breast, and physical exam), other non-recommended tests (e.g. tumor markers, imaging scans), and patients’ beliefs were compared by provider type using multivariate logistic regression. no significant differences in patient self-report of physical exam or mammography prevalence by provider type was observed after adjustment for covariates. receipt of surveillance tests not recommended by asco was higher among survivors who saw an oncologist (tumor marker tests: or = 3.0, 95 % ci 1.5–5.8; and other blood tests: or = 2.0, 95 % ci 1.1–3.5) as compared to those who routinely see a primary care physician. these observed differences persisted after adjustment for age, stage, lapse in insurance, education, or ethnicity. although overutilization of non-recommended tests was observed among women who saw an oncologist, the majority of breast cancer survivors received asco-recommended surveillance regardless of provider type. most breast cancer survivors receive recommended surveillance tests, whether their care is managed by a primary care physician or an oncologist, but some women receive unnecessary testing. women should talk with their providers about tests recommended based on their past breast cancer diagnosis.
