Two emergency declarations have been made previously and one is currently in effect. Based on our experience of a situation that could affect cancer treatment, this study retrospectively examined the correlation between perioperative anticancer therapy and COVID-19 incidence in patients with breast cancer. Patients and Methods: Patients who underwent perioperative anticancer therapy for breast cancer at our hospital from February 2020 to February 2021 were included in this study. The presence or absence of COVID-19, timing of anticancer drug initiation, and clinical data were collected. Results: No cases of COVID-19 were diagnosed in patients receiving perioperative anticancer therapy at our hospital. Conclusion: Regimen modification, active use of supportive care, and patient lifestyle were factors reducing the incidence of COVID-19. %U https://ar.iiarjournals.org/content/anticanres/41/4/2193.full.pdf
