Kaplan‐Meier analysis of mortality in primary tumor subtype among Cancer COIVD‐19 Cohort. (a) Kaplan‐Meier analysis of primary tumor subtype among Cancer COIVD‐19 Cohort. Compared with the COVID‐19 Cohort, COVID‐19 patients with hematologic, brain, nasopharyngeal, digestive system, and lung malignancies showed a significantly high risk of 1‐year all‐cause post‐admission mortality, defined as the high‐risk group; while patients with breast and endocrine, genitourinary, and female genital tumors showed a moderate risk of 1‐year post‐admission mortality with no statistical difference from the COVID‐19 Cohort, defined as the moderate‐risk group. (b) Kaplan–Meier analysis of high and moderate risk stratification of primary tumor subtype among cancer COIVD‐19 Cohort in 1‐year all‐cause post‐admission mortality; (c) Kaplan‐Meier analysis of high and moderate risk stratification of primary tumor subtype among cancer COIVD‐19 Cohort in 12‐month all‐cause post‐discharge mortality
