- W3199520418 abstract "Abstract Background Patients with cancer are at risk for poor COVID-19 outcomes. We aimed to identify cancer-related risk factors for poor COVID-19 outcomes. Patients and Methods We conducted a retrospective cohort study using the University of California Health COVID Research Data Set. This database includes prospectively-collected, electronic health data of patients who underwent testing for SARS-CoV-2 at seventeen California medical centers. We identified adult patients tested for SARS-CoV-2 between February 1, 2020 and December 31, 2020, and selected a cohort of patients with cancer using diagnostic codes. We obtained demographic, comorbidity, laboratory, cancer type, and antineoplastic therapy data. The primary outcome was hospitalization within 30 days after first positive SARS-CoV-2 test. Secondary outcomes were SARS-CoV-2 positivity and composite endpoint for severe COVID-19 (intensive care, mechanical ventilation, or death within 30 days after first positive test). We used multivariable logistic regression to identify cancer-related factors associated with outcomes. Results We identified 409,462 patients undergoing SARS-CoV-2 testing. Of 49,918 patients with cancer, 1,781 (3.6%) tested positive. Patients with cancer were less likely to test positive (OR 0.69, 95%CI 0.66-0.73, P<0.001). BCR-ABL-negative myeloproliferative neoplasms (polycythemia vera, essential thrombocythemia, and primary myelofibrosis) (OR 2.51, 95%CI 1.29-4.89, P =0.007); venetoclax (OR 3.63, 95%CI 1.02-12.92, P =0.046); methotrexate (OR 3.65, 95%CI 1.17-11.37, P =0.026); Asian race (OR 1.92, 95%CI 1.23-2.98, P =0.004); and Hispanic/Latino ethnicity (OR 1.96, 95%CI 1.41-2.73, P <0.001) were associated with increased hospitalization risk. Among 388 hospitalized patients with cancer and COVID-19, cancer type and therapy type were not associated with severe COVID-19. Conclusions In this large, diverse cohort of Californians, cancer was not a risk factor for SARS-CoV-2 positivity. Patients with BCR/ABL-negative myeloproliferative neoplasm and patients receiving methotrexate or venetoclax may be at an increased risk of hospitalization following SARS-CoV-2 infection. Further mechanistic and comparative studies are needed to explain and confirm our findings." @default.
