Abstract
IMPORTANCE Whether the severity and mortality of COVID-19 in patients with cancer have improved in terms of disease management and capacity is yet to be defined. OBJECTIVE To test whether severity and mortality from COVID-19 among patients with cancer have improved during the course of the pandemic. DESIGN, SETTING, AND PARTICIPANTS OnCovid is a European registry that collects data on consecutive patients with solid or hematologic cancer and COVID-19. This multicenter case series study included real-world data from 35 institutions across 6 countries (UK, Italy, Spain, France, Belgium, and Germany). This update included patients diagnosed between February 27, 2020, and February, 14, 2021. Inclusion criteria were confirmed diagnosis of SARS-CoV-2 infection and a history of solid or hematologic cancer. EXPOSURES SARS-CoV-2 infection. MAIN OUTCOMES AND MEASURES Deaths were differentiated at 14 days and 3 months as the 2 landmark end points. Patient characteristics and outcomes were compared by stratifying patients across 5 phases (February to March 2020, April to June 2020, July to September 2020, October to December 2020, and January to February 2021) and across 2 major outbreaks (February to June 2020 and July 2020 to February 2021). RESULTS At data cutoff, 2795 consecutive patients were included, with 2634 patients eligible for analysis (median [IQR] age, 68 [18-77] years ;52.8% men). Eligible patients demonstrated significant time-dependent improvement in 14-day case-fatality rate (CFR) with estimates of 29.8% (95% CI, 0.26-0.33) for February to March 2020;20.3% (95% CI, 0.17-0.23) for April to June 2020;12.5% (95% Cl, 0.06-22.90) for July to September 2020;17.2% (95% CI, 0.15-0.21) for October to December 2020;and 14.5% (95% CI, 0.09-0.21) for January to February 2021(all P < .001) across the predefined phases. Compared with the second major outbreak, patients diagnosed in the first outbreak were more likely to be 65 years or older (974 of 1626 [60.3%] vs 564 of 1008 [56.1%];P = .03), have at least 2 comorbidities (793 of 1626 [48.8%) vs 427 of 1008 [42.4%);P = .001), and have advanced tumors (708 of 1626 [46.4%) vs 536 of 1008 [56.1%]: P < .001). Complications of COVID-19 were more likely to be seen (738 of 1626 [45.4%) vs 342 of 1008 [33.9%];P < .001) and require hospitalization (969 of 1626 [59.8%) vs 418 of 1008 [42.1%);P < .001) and anti-COVID-19 therapy (1004 of 1626 [61.7%) vs 501of 1008 [49.7%);P < .001) during the first major outbreak. The 14-day CFRs for the first and second major outbreaks were 25.6% (95% CI, 0.23-0.28) vs 16.2% (95% CI, 0.13-0.19;P < .001), respectively. After adjusting for country, sex, age, comorbidities, tumor stage and status, anti-COVID-19 and anticancer therapy, and COVID-19 complications, patients diagnosed in the first outbreak had an increased risk of death at 14 days (hazard ratio [HR], 1.85;95% CI, 1.47-2.32) and 3 months (HR, 1.28;95% CI, 1.08-1.51) compared with those diagnosed in the second outbreak. CONCLUSIONS AND RELEVANCE The findings of this registry-based study suggest that mortality in patients with cancer diagnosed with COVID-19 has improved in Europe;this improvement may be associated with earlier diagnosis, improved management, and dynamic changes in community transmission over time.
