ABSTRACT
Background and Aims: Cancers are known to worsen the clinical course of SARS-CoV-2 infection. We aimed to assess health outcome effectors in Coronavirus 19 (COVID-19) cancer patients from different centers in the US. Methods: We retrospectively evaluated medical records of 364 COVID-19 cancer patients from 3 centers in the US (New York, Michigan, and DC) admitted to the hospital between Dec. 2019 to Oct. 2021. Outcomes, symptoms, labs, and comorbidities of cancer patients with COVID 19 (Cases), were analyzed and compared with non-cancer COVID-19 patients (Controls). Results: Among 1934 hospitalized COVID-19 patients, 18.7% (n=364) have an active or previous history of cancer. Cancer patients were older when compared with non-cancer controls (69.7 vs 61.3 years). Among these 364 cancer patients, 222 were African Americans (61.7%) and 121 were Caucasians (33.2%). Cancer patients had an increased length of hospitalization compared to controls (8.24 vs. 6.7 days). The most common types of cancer in cases are prostate cancer (41.5%) and hematological malignancies (10.1%) among males, and breast cancer (41.5%), and head and neck cancers (11.4%) in females. In both genders, lung cancer is associated with high mortality. Patients with a previous history of cancer were more prone to death (p=0.04) than active cancer patients. Cough (23.1%) and fever (19.5%) are the most common symptoms among the cases. In univariate and multivariate analyses, predictors of death among cancer patients were male sex, older age, African American ethnicity/race, asthma, presence or absence of fever, elevated troponin, mechanical ventilation, and previous history of cancer. There is no significant difference in mortality in cancer patients when compared to controls. Abdominal pain (2.2%), diarrhea (3.8%), and vomiting (2%) occurred both in cases and controls but did not associate with death. Albumin is also significantly associated with mortality in cases (p=0.042). AST (54.6%), ALT (12.5%), and Bilirubin (16%) were elevated in the majority of cases. Both AST and ALT alterations have an effect on mortality. Univariate analysis shows that AST is strongly and significantly associated with mortality in cases (p=0.001) but not in controls. ALT is also associated with mortality in cases at the 10% level (p=0.057). Diarrhea is strongly associated with mortality in control (p <0.001) but not in cases. Conclusion: In this retrospective cohort study, we found male sex, and African American race is associated with high mortality. Elevated troponin levels and LFT’s during the hospital stay were significantly associated with poor outcomes. Patients with a previous history of cancer were more prone to death when compared to active cancer COVID-19 patients. Early recognition of cancer COVID-19 patients can help determine appropriate treatment and management plans for better prognosis and outcome.
ABSTRACT
Background and Aims: Initial reports on US COVID-19 showed different outcomes in different races. In this study, we use a diverse large cohort of hospitalized COVID-19 patients to determine predictors of mortality. Methods: We analyzed data from hospitalized COVID- 19 patients (n=5,852) from 8 hospitals. Demographics, comorbidities, symptoms and laboratory data were collected. Results: The cohort contained 3,662 (61.7%) African Americans (AA), 286 (5%) American Latinx (LAT), 1,407 (23.9%), European Americans (EA), and 93 (1.5%) American Asians (AS). Survivors and dead patients' mean ages were 58 and 68 for AA, 58 and 77 for EA, 44 and 61 for LAT, and 51 and 63 for AS. Mortality rates for AA, LAT, and EA were 14.8%, 7.3%, and 16.3%. Mortality increased among patients with the following characteristics: age, male gender, New York region, cardiac disease, COPD, diabetes mellitus, hypertension, history of cancer, immunosuppression, elevated lymphocytes, CRP, ferritin, D-Dimer, creatinine, troponin, and procalcitonin. Use of mechanical ventilation, respiratory failure, shortness of breath (SOB) (p<0.01), fatigue (p=0.04), diarrhea (p=0.02), and increased AST (p<0.01), significantly correlated with death in multivariate analysis. Male sex and EA and AA race/ethnicity had a higher frequency of death. Diarrhea was among the most common GI symptom amongst AAs (6.8%). When adjusting for comorbidities, significant variables were age (over 45 years old), male sex, EA, patients hospitalized in Indiana, Michigan, Georgia, and District of Columbia. When adjusting for disease severity, significant variables were age over 65 years old, male sex, EA as well as having SOB, elevated CRP, and D-dimer. Glucocorticoid usage was associated with an increased risk of COVID- 19 death in our cohort. Conclusion: Among this large cohort of hospitalized COVID-19 patients enriched for African Americans, predictors of mortality include male gender, diarrhea, elevated AST, comorbidities, respiratory symptoms and failure, and elevation of inflammatory- related biomarkers. These findings may reflect the extent of systemic organ involvement by SARS-CoV-2 and subsequent progression to multi-system organ failure. High mortality in AA in comparison with LAT is likely related to a high frequency of comorbidities and older age among AA.
