As shown in Table 3, mortality related to COVID-19 was significantly associated to older age (P < .001 for patients between 60 to 74 years and P = .002 for patients aged 75 years or older), metastatic cancer (P < .001), two or more sites of metastases (P < .001), the presence of lung (P < .001) or bone metastases (P = .001), non-curative treatment or best supportive care intent (P < .001), higher C-reactive protein levels (P = .002), admission due to COVID-19 (P = .009), and antibiotics use (P = .02). The gene discussed is CRP; the disease is metastatic malignant neoplasm.
