P104 COVID-19 mortality in cancer patients on systemic anti-cancer treatments during the second UK SARS-CoV-2 wave

Abstract

P104 Table 1Mortality rate after presentation of COVID-19 by: tumour type, time from cancer diagnosis, cancer stage, progression of disease, and systemic anti-cancer treatment (SACT).

There was no evidence cancer patients on systemic anti-cancer treatments possessed higher mortality from COVID-19 disease, which correlates with findings from COVID-19 and cancer registries1. Patients that did not receive SACT within 3 months before COVID-19 and therefore more likely to have palliative treatment did demonstrate high mortality. Larger studies are needed to confirm the risk of mortality and timing of SACT before COVID-19 disease.ReferenceLee AJ, et al. British Journal of Cancer 2021;124:1777–1784.
