Objectives: Current coronavirus disease 2019 (COVID-19) guidelines recommend delaying clinical care for all affected cancer patients, including incidentally diagnosed asymptomatic infections. This retrospective study conducted in a safety-net hospital in Houston examines the care delivery of asymptomatic COVID-19 cancer patients and how their diagnosis affected their care.
Methods: A retrospective chart review was conducted on cancer patients with a documented positive SARS-CoV-2 laboratory result in the Harris Health System in Houston, Texas. Patient demographics, treatment delays, and patient outcomes were analyzed.
Results: Thirteen percent (n=24) of all patients with cancer and COVID-19 diagnosis (n=181) were asymptomatic and 96% had a solid organ malignancy. Among asymptomatic patients, 44% (n=11) of them experienced a median treatment delay of 33 days and 21% (n=5) transitioned to hospice. No patients had progression of disease at first evaluation after recovering from COVID-19 diagnosis. Asymptomatic patients were more likely to have a worse ECOG performance status, metastatic disease, and charity insurance as compared with symptomatic patients.
Conclusions: This study supports the safety of our current isolation guidelines for all COVID-19 asymptomatic cancer patients. While treatment delays occurred, they did not appear to significantly impact overall care. Differences in care delivery and health care usage patterns between symptomatic and asymptomatic patients demonstrate the need for continued studies in vulnerable populations.
