The alteration of laboratory blood tests (leukocytes, neutrophils, lymphocytes, thrombocytes, prothrombin time, activated partial thromboplastin time, CRP, procalcitonin, bilirubin and troponin) were associated with outcome of cancer patients with COVID-19 (p=0.023, p=0.002, p=0.027, p=0.045, p<0.001, p<0.001, p<0.001, p=0.003, p=0.005, p<0.001; respectively). The gene discussed is CRP; the disease is cancer.
