SAN DIEGO – A new study finds that the risk of skin cancers in organ transplant recipients may vary widely by ethnicity.
“The most important findings from our study are the high rates of keratinocyte neoplasms observed in our white Northern European patients, but also in those of Far East Asian descent. Dermatologists should also appreciate the high risk of Kaposi’s sarcoma (KS) in patients originating from Sub-Saharan Africa,” Jonathan Kentley, MBBS, of Royal London Hospital, said in an interview. He presented the study findings at the annual meeting of the American Academy of Dermatology.
For the study, Dr. Kentley and colleagues sought to better understand.
They analyzed an organ transplant center database for the years 1989-2016, and tracked 1,304 consecutive patients – which included 1,125 with skin problems. The overall population was 64% male with a median age in the early 40s, and almost all (1,276) had undergone renal transplants. A relative handful underwent liver, lung, heart, and pancreas transplants.
The majority of patients (885) were white Northern Europeans, but there were also significant numbers of people with South Asian (202), black African/Caribbean (131) and white/Mediterranean (52) heritage. A small number were Far East Asian (26) and Middle Eastern (8). The median follow-up time for the ethnic groups varied from about 5 years to about 12 years.
The researchers found that basal cell carcinoma was most common in white Northern European patients, at nearly 25%, with other groups under 10%. SCC was common in white Northern European patients and Far East Asians, both at nearly 25%.
