Impact of COVID-19 Restrictions on Stage of Breast Cancer at Presentation and Time to Treatment at an Urban Safety-Net Hospital

BACKGROUND: COVID-19 disrupted health systems across the country. Pre-pandemic, patients accessing our urban safety-net hospital presented with three-fold higher rates of late-stage breast cancer than other Commission-on-Cancer sites. We sought to determine the effect of the COVID-19 pandemic on stage of breast cancer presentation and time to first treatment at our urban safety-net hospital. METHODS: An Institutional Review Board-approved cohort study of newly diagnosed breast cancer patients was conducted at our safety-net hospital comparing a COVID cohort (March 2020–February 2021, n = 82) with a pre-COVID cohort (March 2018–February 2019, n = 90). Demographic information, stage at presentation, and time to first treatment—subdivided into time from symptom to diagnosis and diagnosis to treatment—were collected and analyzed for effect of COVID pandemic. RESULTS: Cohorts were similar in age, race, and payor. More patients had late-stage disease during COVID (32%) than pre-COVID (19%, p = 0.05). There was a significantly longer time to first treatment during COVID (p = 0.0001) explained by a significantly longer time from symptom to diagnosis (p = 0.0001), with no difference in time from diagnosis to treatment. CONCLUSION: It was significantly more likely for patients to present to our safety-net hospital with late-stage breast cancer during COVID than pre-COVID. There was longer time to first treatment during COVID, driven by the increased time from symptom to diagnosis. Patients may have perceived that care was inaccessible during the pandemic or had competing priorities, driving delays. Efforts should be made to minimize disruption to safety-net hospitals during future shut-downs as these are among the most vulnerable patients.
