Characteristics and outcomes of cancer patients with covid-19 at a safety-net hospital

Patients with cancer are a vulnerable population during the COVID-19 pandemic due to underlying immunosuppression, pre-existing comorbidities, and poor nutrition. There is a lack of data describing the disease course of cancer patients with COVID-19 disease. Therefore, we analyzed data from cancer patients with COVID-19 who were admitted to our hospital. Cancer patients were categorized into two groups as survivors and non-survivors of COVID-19. Among 68 cancer patients with COVID-19, 27% of patients were admitted to ICU, and 37% of the patients died. The median age was 72, and non-survivors were older than survivors (p = 0.001). Non-survivors had higher comorbidity scores, late-stage cancer, and worse ECOG performance status than survivors (all p values<0.005). Non-survivors also had significantly lower lymphocyte count and albumin level but higher lactate dehydrogenase, C-reactive protein, fibrinogen, troponin, and ferritin levels than survivors. On multivariable analysis, increased age and mechanical ventilation were associated with increased odds of death. We report no association between anti-cancer treatments and mortality from COVID-19 disease. In summary, cancer patients have higher mortality of COVID-19 infection than the general population. In addition to generally known risk factors, the high mortality rate in cancer patients with COVID-19 is associated with several cancer-specific factors.
