Abstract Introduction COVID-19 infection is associated with an increased risk of complications, prolonged hospitalization, and mortality despite vaccination in patients with cancer. Evusheld (tixagevimab-cilgavimab) was granted emergency use approval in December 2021 for pre-exposure prophylaxis based on preliminary results from the PROVENT trial. However, studies evaluating the impact of Evusheld in cancer patients in the real-world are limited. In this study, we assessed the impact of Evusheld on the incidence and severity of COVID-19 infection in cancer patients at our institution. Methods and Materials We conducted a retrospective descriptive study at our institution on patients with current and prior history of cancer diagnosis regardless of treatment history who received Evusheld between December 2021 and March 2022. The primary outcome was incidence of COVID-19 during a 6 month follow up period. Secondary outcomes included rate of hospitalization related to COVID-19 and associated mortality. Results A total of 228 patients were included, 43% of which received 2 doses of Evusheld during the study period. Twenty-nine patients (12.7%, 95% CI 9.4% – 18.7%) developed COVID-19, with an average time to diagnosis of 2.5 months (SD 1.6) from receiving Evusheld. Most had hematologic malignancies (68.4%) and were receiving active chemotherapy (71.5%) at the time of diagnosis. Five (17.2%) patients were hospitalized for COVID-19, of whom 4 had hematological malignancy. One patient with hematological malignancy required mechanical ventilation and died. Conclusion Overall, the incidence of COVID-19 following Evusheld was higher than in the PROVENT trial. Infections appeared to be more common and severe in patients with hematologic malignancies.

ImportanceLip, oral, and pharyngeal cancers are important contributors to cancer burden worldwide, and a comprehensive evaluation of their burden globally, regionally, and nationally is crucial for effective policy planning.ObjectiveTo analyze the total and risk-attributable burden of lip and oral cavity cancer (LOC) and other pharyngeal cancer (OPC) for 204 countries and territories and by Socio-demographic Index (SDI) using 2019 Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study estimates.Evidence ReviewThe incidence, mortality, and disability-adjusted life years (DALYs) due to LOC and OPC from 1990 to 2019 were estimated using GBD 2019 methods. The GBD 2019 comparative risk assessment framework was used to estimate the proportion of deaths and DALYs for LOC and OPC attributable to smoking, tobacco, and alcohol consumption in 2019.FindingsIn 2019, 370 000 (95% uncertainty interval [UI], 338 000-401 000) cases and 199 000 (95% UI, 181 000-217 000) deaths for LOC and 167 000 (95% UI, 153 000-180 000) cases and 114 000 (95% UI, 103 000-126 000) deaths for OPC were estimated to occur globally, contributing 5.5 million (95% UI, 5.0-6.0 million) and 3.2 million (95% UI, 2.9-3.6 million) DALYs, respectively. From 1990 to 2019, low-middle and low SDI regions consistently showed the highest age-standardized mortality rates due to LOC and OPC, while the high SDI strata exhibited age-standardized incidence rates decreasing for LOC and increasing for OPC. Globally in 2019, smoking had the greatest contribution to risk-attributable OPC deaths for both sexes (55.8% [95% UI, 49.2%-62.0%] of all OPC deaths in male individuals and 17.4% [95% UI, 13.8%-21.2%] of all OPC deaths in female individuals). Smoking and alcohol both contributed to substantial LOC deaths globally among male individuals (42.3% [95% UI, 35.2%-48.6%] and 40.2% [95% UI, 33.3%-46.8%] of all risk-attributable cancer deaths, respectively), while chewing tobacco contributed to the greatest attributable LOC deaths among female individuals (27.6% [95% UI, 21.5%-33.8%]), driven by high risk-attributable burden in South and Southeast Asia.Conclusions and RelevanceIn this systematic analysis, disparities in LOC and OPC burden existed across the SDI spectrum, and a considerable percentage of burden was attributable to tobacco and alcohol use. These estimates can contribute to an understanding of the distribution and disparities in LOC and OPC burden globally and support cancer control planning efforts.

Background There are limited data on the outcomes of acute myocardial infarction–cardiogenic shock (AMI-CS) in patients with concomitant cancer. Methods A retrospective cohort of adult AMI-CS admissions was identified from the National Inpatient Sample (2000–2017) and stratified by active cancer, historical cancer, and no cancer. Outcomes of interest included in-hospital mortality, use of coronary angiography, use of percutaneous coronary intervention, do-not-resuscitate status, palliative care use, hospitalization costs, and hospital length of stay. Results Of the 557,974 AMI-CS admissions during this 18-year period, active and historical cancers were noted in 14,826 (2.6%) and 27,073 (4.8%), respectively. From 2000 to 2017, there was a decline in active cancers (adjusted odds ratio, 0.70 [95% CI, 0.63–0.79]; P < .001) and an increase in historical cancer (adjusted odds ratio, 2.06 [95% CI, 1.89–2.25]; P < .001). Compared with patients with no cancer, patients with active and historical cancer received less-frequent coronary angiography (57%, 67%, and 70%, respectively) and percutaneous coronary intervention (40%, 47%, and 49%%, respectively) and had higher do-not-resuscitate status (13%, 15%, 7%%, respectively) and palliative care use (12%, 10%, 6%%, respectively) (P < .001). Compared with those without cancer, higher in-hospital mortality was found in admissions with active cancer (45.9% vs 37.0%; adjusted odds ratio, 1.29 [95% CI, 1.24–1.34]; P < .001) but not historical cancer (40.1% vs 37.0%; adjusted odds ratio, 1.01 [95% CI, 0.98–1.04]; P = .39). AMI-CS admissions with cancer had a shorter hospitalization duration and lower costs (all P < .001). Conclusion Concomitant cancer was associated with less use of guideline-directed procedures. Active, but not historical, cancer was associated with higher mortality in patients with AMI-CS.
