Purpose: The COVID-19 pandemic has substantially changed social practices, economic stability, and access to medical care that may significantly affect cancer patients, especially those undergoing active treatment. We characterized the pandemic's influence on healthcare delivery, behavioral health, and financial stress in cancer patients. Methods: We included data from N = 1,253 adult cancer patients, who visited HCI in the last 4 years, consented to the Total Cancer Care study, and completed a COVID-19 survey as part of the COPES consortium. The survey was administered between Aug and Sept 2020 and included questions on change/cancellation of medical visits, change in exercise and alcohol consumption, daily life, social interactions, and financial stress since March 2020. Results: The cohort's mean age was 60.4 (19–92) years, with 54% female, 68% non-Hispanic White, 41% retired, 43% employed full or part-time, and 24% living in rural counties. Among the 27% of patients who reported receiving current treatment at HCI, 30% had to change or cancel a medical visit due to the pandemic, with 2% reported a change/cancellation in a biopsy, surgery, radiotherapy, and chemotherapy; 5% reported a change/cancellation in imaging; and 3% and 23% reported a change/cancellation in cancer screening and doctor's visit, respectively. 18% rescheduled an appointment to a telehealth visit. Changes in exercise habits due to the pandemic were common (47%), with 10% no longer exercising regularly, 21% exercising less, and 11% exercising more than before. 5% reported increased alcohol consumption, while 6% reported a decrease. Most patients (84%) experienced a change in their daily lives (ranging from somewhat to a lot of change). 69% had fewer social interactions, and 49% reported financial stress due to the pandemic, with 11% reporting being quite a bit/very much financially stressed. Conclusions: These findings suggest that within approximately the first 6 months, the COVID-19 pandemic had a substantial impact on cancer patients' lives, with adverse effects on health behaviors and financial stress. Healthcare delivery continued for essential cancer care but was disrupted for other services, such as cancer screening. Further analyses are underway. Funding: U01CA206110 and R01CA211705.
