Melanomas of the conjunctiva (CM) are very deadly. Knowledge regarding the social factors, especially insurance status such as Medicaid enrollment, that can affect CM mortality is limited. We will be using a national database, called SEER-Medicaid, to investigate whether being enrolled in Medicaid affects survival rates. We will be analyzing all patients diagnosed with CM between the years 1999-2008 and categorizing them as Medicaid or not in Medicaid. We will only analyze adults between the age of 18 and 65, as children may have different Medicaid benefits and elderly individuals may also be enrolled in Medicare. We will used advanced statistics to construct five-year survival curves of CM patients and to evaluate the following variables and how they can affect risk of death: age, race, sex, marital status, duration of Medicaid enrollment, therapy, poverty level, region of the United States, tumor location, rural/urban, tumor size, county English proficiency, county education level, county % minority population, reasons for surgery or no surgery, and other non-standard therapy. Because Medicaid patients have historically been observed to have worse health-care access and survival across many cancer types, we expect that CM patients on Medicaid to also have worse outcomes and survival.
