ABSTRACT
BACKGROUND/

AIM:

The anticipation of radiotherapy can cause distress and sleep disorders, which may be aggravated by the COVID-19 pandemic. This study investigated sleep disorders in a large cohort of patients with breast cancer before and during the pandemic. PATIENTS AND

METHODS:

Twenty-three characteristics were retrospectively analyzed for associations with pre-radiotherapy sleep disorders in 338 patients. Moreover, 163 patients presenting before and 175 patients presenting during the COVID-19 pandemic were compared for sleep disorders.

RESULTS:

Sleep disorders were significantly associated with age ≤60 years (p=0.006); high distress score (p<0.0001); more emotional (p<0.0001), physical (p<0.0001) or practical (p<0.0001) problems; psycho-oncological need (p<0.0001); invasive cancer (p=0.003); chemotherapy (p<0.001); and hormonal therapy (p=0.006). Sleep disorders were similarly common in both groups (prior to vs. during the pandemic 40% vs. 45%, p=0.38).

CONCLUSION:

Although additional significant risk factors for sleep disorders were identified, the COVID-19 pandemic appeared to have no significant impact on sleep disorders in patients scheduled for irradiation of breast cancer.
