The impact of the COVID-19 pandemic on quality of life, physical and psychosocial wellbeing in breast cancer patients and survivors - A prospective, multicenter cohort study

ABSTRACT

PurposeThe COVID-19 pandemic and the resulting social distancing and lockdown measures are having a substantial impact on daily life and medical management of people with breast cancer. We evaluated to what extent these changes have affected quality of life and physical, and psychosocial wellbeing of people (being) treated for breast cancer. MethodsThis study was conducted within the prospective Utrecht cohort for Multiple BREast cancer intervention studies and Long-term evaluation (UMBRELLA). Shortly after the implementation of COVID-19 measures, extra questionnaires were sent to 1595 cohort participants, including standard UMBRELLA quality of life (EORTC) questionnaires. Patient-reported outcomes (PROs) were compared to the most recent PROs collected within UMBRELLA before COVID-19. The impact of COVID-19 on PROs was evaluated using mixed models analysis. ResultsIn total, 1051 patients (66%) completed the questionnaires. One third (n = 327, 31%) reported a higher threshold to contact their general practitioner due to COVID-19. A significant deterioration in emotional functioning was observed (82{middle dot}6 to 77{middle dot}9, p < 0.001) and 505 (48%, 95% CI 45-51) patients reported moderate to severe loneliness. Small significant improvements were observed in QoL, physical-, social- and role functioning scores. In the subgroup of 51 patients under active treatment, there was a strong deterioration in social functioning (69{middle dot}8 to 5{middle dot}0, p = 0{middle dot}03). ConclusionDue to COVID-19, patients (being) treated for breast cancer are less likely to contact physicians, and experience a deterioration in emotional functioning. Patients undergoing active treatment report a strong drop in social functioning. One in two patients reports (severe) loneliness. Online applications facilitating peer contact and e-mental health interventions could support mental health and social interaction times of total lockdown or social distancing.
