The incidence of non-melanoma skin cancer (NMSC) is much higher for Caucasians than Hispanics or Asians, but Hispanic patients are significantly younger than Caucasian or Asian patients, according to research presented at the annual meeting of the American Academy of Dermatology, held in San Francisco.

Tiffany Loh, from the University of California, San Diego, School of Medicine, and colleagues compared the incidence of NMSC among Hispanic, Asian, and Caucasian patients in a five-year retrospective chart review. Data were included for 4,029 cases of NMSCs.

The researchers found that 96.3 percent of patients were Caucasian, 2.9 percent Hispanic, and 0.8 percent Asian. Hispanic patients were significantly younger (average age, 62.1 years) than Caucasians (average age, 66.6 years; P = 0.003) and Asians (average age, 70.3 years; P = 0.023).

Among Caucasians, most NMSCs occurred in men (64 percent), while for Hispanics and Asians, more cases occurred in females (66.1 and 60.6 percent, respectively).

“The rise of NMSCs in Hispanics and Asians, especially among women, is concerning given that they are the fastest growing ethnic populations in the United States. Proper photoprotection counseling should be stressed to minorities to prevent further increase of NMSC,” the authors write.

“Future large multi-center studies focusing on NMSC features (not only those indicated for Mohs micrographic surgery) and risk factors among minorities are necessary to further elucidate our findings.”
