Abstract: Background: The incidence rates of skin cancers in Caucasian populations are increasing. There is little information on skin cancer trends in Asians, who have distinctly different skin types. Objective: We sought to study skin cancer incidence rates and time trends among the 3 Asian ethnic groups in Singapore. Methods: We analyzed skin cancer data from the Singapore Cancer Registry from 1968 to 2006 using the Poisson regression model. Results: There were 4044 reported cases of basal cell carcinoma, 2064 of squamous cell carcinoma, and 415 of melanoma. Overall skin cancer incidence rates increased from 2.9/100,000 in 1968 to 1972 to 8.4/100,000 in 1998 to 2002, declining to 7.4/100,000 in 2003 to 2006. Among older persons (≥60 years), basal cell carcinoma rates increased the most, by 18.9/100,000 in Chinese, 6.0/100,000 in Malays, and 4.1/100,000 in Indians from 1968 to 1972 to 2003 to 2006. Squamous cell carcinoma rates among those aged 60 years and older increased by 2.3/100,000 in Chinese and by 1/100,000 in Malays and Indians. Melanoma rates were constant for all 3 races. Skin cancer rates among the fairer-skinned Chinese were approximately 3 times higher than in Malays and Indians, who generally have darker complexions. Limitations: Although appropriate population denominators were used, lack of data from 2007 could have affected the results for the last time period, which comprised 4 instead of 5 years. Conclusion: Incidence rates of skin cancer in Singapore increased from 1968 to 2006, especially among older Chinese. © 2009 American Academy of Dermatology, Inc.
