Impact of COVID-19 on the management of patients with thoracic cancers in a tertiary referral center

INTRODUCTION: Severe acute respiratory syndrome coronavirus (SARS-CoV)-2 has spread worldwide in 2020 leading the World Health Organization to declare a pandemic. Patients with thoracic cancers have been reported at higher risk to develop severe disease, and die from COVID-19. In this setting, clinical practice recommendations for the management of patients were published. We report here how these guidelines were implemented in a routine practice setting. METHODS: We retrospectively collected the characteristics, treatment regimen and modification, as well as COVID-19 status and death for all patients with thoracic malignancies scheduled for an appointment at Institute Curie from March 23(rd) to April 17(th) 2020. RESULTS: A total of 339 patients were included. Treatment strategy was modified for a total of 110 (32 %) patients because of COVID-19; these modifications were in accordance with guidelines for 92 % of patients. The majority of dose modifications were related to immune checkpoint inhibitors, for which switch to flat dosing every 4–6 weeks was made. A total of 5 (1.5 %) patients were diagnosed with COVID-19 disease, 1 of whom died from disease complication. CONCLUSION: Our study provides a unique insight in the decision making for patients with thoracic malignancies in the setting of COVID-19 outbreak, showing how guidelines were implemented in the clinic, and what may be optimized in the clinical practice of thoracic oncology in the future.
