The Challenge of COVID-19: The Biological Characteristics and Outcomes in a Series of 130 Breast Cancer Patients Operated on During the Pandemic.

The worldwide outbreak of the 2019 novel coronavirus disease (COVID-19) emerged in Wuhan, China close to the end of 2019. We analyse the clinical characteristics and management outcomes of a small group of patients who have been treated in the early stage of the COVID-19 disease, and discuss the impact of the pandemic on the service delivered to breast cancer patients. Material We analysed a cohort of 130 breast cancer patients who underwent elective surgical procedures during the early period of COVID-19. The patients were operated on in the period from March 16th, 2020 to May 18th, 2020. All the patients were female, with an age range of 33-88 years, with a median age of 57.6 years. Most of the cases were admitted as a day case surgery after passing through a preoperative screening pathway, which was developed gradually. Patients were contacted by phone after their surgery to ensure that they have had no symptoms and were reviewed in person two weeks after the procedure with histology results. Only one patient developed COVID-19 symptoms after surgery and recovered. Early and careful implementation of modified practice policies during emerging situation of viral pandemics will reduce the risk of perioperative complications, reduce the risk of patient to staff to patient transmission and minimize the negative impact of COVID-19 on breast cancer management.
