ABSTRACT
Background: Patients with cancer have worse outcomes from COVID-19 infection. However, the specific impact of COVID-19 on patients with (HNC) is largely unknown. The COVID-19 and Cancer Consortium (CCC19) maintains an international registry (NCT04354701) aimed to investigate the clinical course and complications of COVID-19 in patients with cancer. Here, we report severity of COVID-19 and its complications among HNC patients. Methods: The CCC19 registry was queried for patients with HNC and laboratory confirmed SARS-CoV-2 infection. The co-primary outcomes were severity of COVID-19 illness on an ordinal scale (0: no complications;1: hospitalized, no oxygen (O2);2: hospitalized, required O2;3: ICU admission;4: mechanical ventilation (MV);5: death), and severity of complications (mild, moderate, serious). The outcomes were further stratified by demographics, recent treatment (systemic vs local;surgery, radiation (RT) vs systemic), treatment intent (palliative vs curative), and cancer status (remission, responding, stable, progressing). Results: From March 2020 to December 2021, 356 HNC patients were identified. Median age was 65 (interquartile range 58-74), 29% were female, 56% were white, 67% were former or current smokers, 20% had a BMI >30, 15% had an ECOG performance status >2, and 57% had >2 comorbidities. 154 (43%) had no complications, 61 (17%) were hospitalized without O2, 135 (38%) were hospitalized with O2, 50 (14%) required ICU, 32 (9%) required MV, and 74 (21%) died. 88 (25%) had mild, 59 (17%) had moderate, and 132 (37%) had serious complications. 33% of patients who received systemic therapy and 30% who received RT within 3 mo prior to COVID-19 diagnosis died. Mortality was higher in patients receiving palliative when compared to curative intent treatment (44% vs 16%). In addition, 50% of patients with actively progressing cancer, and 45% who had serious complications died. Importantly, 37 (n=12 palliative systemic therapy and n=25 local therapy) patients had a treatment delay due to COVID-19 diagnosis. Conclusions: Our study is the largest cohort to date describing COVID-19 outcomes in HNC patients and suggest a high rate of mortality even in those receiving local and curative intent treatment. Variables stratified by COVID-19 severity. Note: Ordinal levels 3 and 4 not shown due to small case numbers.
ABSTRACT
Background: Racial/ethnic minorities have disproportionately increased risk of contracting COVID-19 and experiencing severe illness;they also have worse breast cancer (BC) outcomes. COVID-19 outcomes among racial/ethnic minorities with BC are currently unknown. We sought to compare clinicopathologic characteristics and COVID-19 outcomes stratified by race/ethnicity. Methods: The COVID-19 and Cancer Consortium registry (NCT04354701) was used to identify patients with invasive BC and laboratory-confirmed SARS-CoV-2 diagnosed in the U.S. between 2020-03-06 and 2021-02-04. The primary analysis was restricted to women who selfidentified as non-Hispanic White (NHW), nonHispanic Black (NHB), or Hispanic (H). Demographic, cancer characteristics, and COVID-19 outcomes were evaluated. COVID-19 outcomes included: hospital admission, intensive care unit (ICU) admission, mechanical ventilation, death within 30 days of COVID-19 diagnosis and death from any cause during follow-up. Descriptive statistics were used to compare clinicopathologic characteristics and Fisher exact tests were used to compare COVID19 outcomes across the 3 racial/ethnic groups. Results: A total of 1133 patients were identified of which 1111 (98%) were women;of which 575 (52%) NHW, 243 (22%) NHB, 183 (16%) H, and 110 (10%) other/unknown. Baseline characteristics differed among racial/ethnic groups. H were younger (median age: NHW 63y;NHB 62y;H 54y) and more likely to be never smokers (NHW 62%;NHB 62%;H 78%). NHB had higher rates of obesity (NHW 40%;NHB 54%;H 46%), diabetes (NHW 16 %;NHB 32%;H 20%) and combined moderate and severe baseline COVID-19 at presentation (NHW 28%;NHB 42%;H 28%). Cancer characteristics are as shown (Table). Significant differences were observed in outcomes across racial/ethnic groups including higher rates of hospital admission (NHW 34%;NHB 49%;H 34%;P <0.001), mechanical ventilation (NHW 3%;NHB 9%;H 5%;P=0.002), 30-day mortality (NHW 6%;NHB 9%;H 4%;P=0.043) and total mortality (NHW 8%;NHB 12%;H 5%;P=0.05) among NHB compared to NHW and H. Conclusions: This is the largest study to show significant differences in COVID-19 outcomes by racial/ethnic groups of women with BC. The adverse outcomes in NHB could be due to higher moderate to severe COVID-19 at presentation and preexisting comorbidities. H did not have worse outcomes despite having more active disease and recent anti-cancer therapy, including with cytotoxic chemotherapy - potentially due to younger age and nonsmoking status.
