Cancers disproportionately affecting the New York state transgender population, 1979-2016

Objectives. To summarize what is known about cancer among the transgender population in New York State. Methods. We identified transgender patients diagnosed between 1979 and 2016 in the New York State Cancer Registry using reported sex, text search of the case abstract, and linkage to statewide hospitalization records. Results. We identified 230 transgender patients, including 125 natal males, 48 natal females, and 57 with unknown natal sex. Median age at diagnosis was 47.4 years, compared with 66.0 years for all patients.Transgender patients were more than 2.5 times more likely to use cigarettes than were other cancer patients. Kaposi sarcoma had the highest proportional incidence ratio (71.7). Conclusions. In New York State, HIV-and human papillomavirus-related cancers disproportionately affect the transgender population. Public Health Implications. To our knowledge, this is the first report of cancer among the transgender population that incorporates more detailed codes that took effect in 2015. Awareness of the differences in transgender cancer incidence from the general population is vital to ensure that necessary preventive care and screenings are accessible and offered appropriately to this population.
