*Death due to the cancer or other causes was decided by the SEER (NCI) classification algorithm using the TCOD and TCR from 2004 until Dec. 31, 2016; survival information of patients not included in the TCOD were obtained from the beneficiary registry of NHIRD at Dec. 31, 2015; the latter were all considered alive.
**The percentage is calculated by deleting the cells whose case number < 5. The 11 most common comorbidities for these 5 cancers in the order of their numbers are: HT UC (98,458), DM W/O CC (50,617), HT C (43,723), COPD (40,508), Ulcer (39,312), Mild LD (34,000), CVD (29,634), DM W CC (17,034), CRF (12,569), CHF (12,116) and Dementia (7526).
