  1. Percentages should be interpreted as the proportion of the super column and row that receive the indicated treatment. For example, among concordant cases, 68.0% receive chemo- or radiotherapy. Among concordant cases, 87.0% of women receive surgery. Among newly-captured cases, 75.5% of patients with colon cancer receive chemo- or radiotherapy. Some patients receive both surgery and chemo- or radiotherapy, so the 4 right-most columns do not sum to the total. *The proportion of total cases with unknown site is 0.22%
