Impact of COVID-19 pandemic on breast surgery and breast reconstruction in a Japanese university hospital setting.
Abstract The new coronavirus disease (COVID-19) is spreading worldwide. In Japan, the number of people infected has been increasing since March 2020. The COVID-19 pandemic has had a significant impact on hospitals, although Tokyo, Japan did not experience a collapse of the medical system. Patients were triaged and prioritized due to surgical limitations during the pandemic period. The purpose of this study was to determine how patients with breast cancer or breast reconstruction were affected by the COVID-19 pandemic at a university hospital in Tokyo. In this retrospective chart review we investigated how patients were treated, including surgical postponements during three periods: April to July 2020, August to November 2019 (after the Allergan recall), and April to July 2019. More than half of breast surgeries and breast reconstructions had to be postponed during the COVID-19 pandemic, and the number of candidates for surgery was also lower compared to the pre-pandemic periods. Triage of patients with breast cancer did not result in any adverse oncological outcomes for these patients. COVID-19 has had a major impact on breast cancer surgery and breast reconstruction, and there was substantial postponement of surgery. Due to triage and prioritization, no patients experienced disease progression in the short-term period, demonstrating that our strategy was appropriate.
