abstract
PURPOSE: Follow-up care of early breast cancer (EBC) patients usually includes routinely scheduled physical examinations. While ASCO guidelines recommend a physical exam every three to six months for the first three years, little evidence supports this schedule. We evaluated recurrence detection of patients transferred into a single centre survivorship program that follows ASCO recommendations. METHODS: Patients with EBC referred to the Wellness Beyond Cancer Program (WBCP) who had breast cancer recurrence between February 1, 2013, and January 1, 2019 were reviewed. Descriptive analyses were used to present patient and disease characteristics stratified by type of recurrence and mode of cancer detection. RESULTS: Of 206 recurrences, 135 were distant recurrences (65.5%), 41 were ipsilateral breast recurrences (19.9%), and 30 were contralateral breast primaries (14.6%). Distant recurrences were primarily detected via patient-reported symptoms (125/135, 92.6%). 53.7% (22/41) of ipsilateral breast recurrences were detected by patients and 41.5% (17/41) by routine imaging. Contralateral breast primaries were primarily detected by imaging 83.3% (25/30) and patient-reported symptoms 16.7% (5/30). Only 2/206 (1.14%) recurrences/new primaries were detected by healthcare providers at routinely scheduled follow-up visits. CONCLUSIONS: Despite following ASCO guidelines, healthcare providers rarely detect recurrences at routinely scheduled follow-up appointments. Our data suggests that approximately 35, 000 follow-up visits were required for healthcare providers to detect these 2 recurrences. While reduced in-person visits may affect other aspects of follow-up care (e.g. toxicity management), it appears unlikely, provided patients attend regular screening tests, that less frequent in-person follow-up is associated with worse breast cancer-related outcomes.
