Of the 52 patients admitted to the hospital with COVID-19, no differences in leukocyte count (p = 1.000), absolute neutrophil count (p = 0.665), monocyte count (p = 0.704), lymphocyte count (p = 0.118), platelet count (p = 0.992), albumin (p = 0.347), total bilirubin (p = 0.358), creatinine (p = 0.795), blood urea nitrogen (p = 0.261), creatine kinase (p = 0.336), lactate dehydrogenase (p = 0.894), D-dimer (p = 0.812), prothrombin time (p = 0.177), CRP (p = 0.722), IL-6 (p = 0.186), or IL-2R (p = 0.862) were noted between cancer patient group and the noncancer patient group (Table 3). Here, IL2RA is linked to COVID-19.
