Health Care Utilization and Follow-Up Care in Young Adult Breast Cancer Survivors

PURPOSE Given the extended survivorship of young adults with breast cancer, characterizing health care utilization and adherence to surveillance guidelines can inform gaps in care. PATIENTS AND METHODS Patients age 40 years and younger at diagnosis of stage 0-III breast cancer enrolled in a prospective cohort study completed a survey 7 years after diagnosis assessing receipt of care and surveillance. We evaluated factors associated with transition to a primary care provider (PCP) for cancer-related follow-up and adherence to mammography and bone density scans. RESULTS Among 660 women, 92% reported having a PCP, although for cancer-related follow-up, 57% saw only an oncology provider, 29% saw both a PCP and oncology provider. In the past 2 years, 68% reported getting a flu shot, 76% a pap test/pelvic examination, 56% cholesterol screening, and 42% (n = 232 endocrine therapy [ET] users) a bone density scan. Among women who had a unilateral mastectomy or lumpectomy (n = 356), 82% reported a mammogram in the past year. In multivariate analyses, those with stage 0 ( v I disease) were more likely to see a PCP for follow-up ( v PCP + oncology provider); ET users and those more concerned about recurrence were less likely. Patients with human epidermal growth factor receptor 2-positive (HER2) disease were more likely to adhere to mammography; those with a BRCA mutation and those with a unilateral mastectomy were less likely. Patients with a BRCA mutation and who had chemotherapy were more likely to report a bone density scan. CONCLUSION Although most have a PCP, over half of young survivors continue to see an oncology provider for follow-up in long-term survivorship. Mammography uptake was high; uptake of other health maintenance practices was lower. Identification of barriers/facilitators to receipt of guideline-concordant care may inform strategies to optimize survivorship.
