Our study supports reported differences between privately insured, Medicaid/welfare, and uninsured persons for colorectal and breast cancers in 2 other states in the United States.10,14,15,38 Ayanian et al,10 who studied New Jersey women aged 35 to 64 years with breast cancer, reported that the adjusted (for age, race, marital status, household income, coexisting diagnoses, and disease stage) risk of death was 49% higher for uninsured patients and 40% higher for Medicaid patients than for privately insured patients during the 54 to 89 months after diagnosis. Roetzheim and colleagues,14,15 who studied Florida residents with colorectal and breast cancers, found that those who were uninsured or insured by Medicaid (colorectal and breast) or commercial health maintenance organizations (breast) had higher mortality rates (adjusted for age, sex, stage at diagnosis, treatment, comorbidity, marital status, smoking status, and community measures of socioeconomic status) than patients with commercial fee-for-service insurance. Bradley et al38 also found that people 65 years and younger who were receiving Medicaid had a higher risk of death from the disease (breast, cervix, lung, prostate, or colon carcinoma) than did patients older than 65 years and receiving Medicaid or Medicare. None of the 4 studies reported relative survival or used life tables in the estimation of risks, as we did, which would have corrected for the competing causes of mortality. Finally, the overall 3-year survival proportion estimates in our study are lower than those reported from the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) program for roughly the same period for all 4 sites.56 The fact that Kentucky is a relatively poor state,57 might have affected the comparatively lower survival proportions reported here.
