Risk factors for keratinocyte carcinoma skin cancer in nonwhite individuals: A retrospective analysis

Abstract

population will consist of nonwhite individuals by the year 2043, it is essential that both physicians and patients are educated about skin cancer in nonwhite persons. Objective: To update the epidemiology, investigate specific risk factors, and facilitate earlier diagnosis and intervention of keratinocyte carcinoma in nonwhite individuals.

Methods: Institutional review board–approved retrospective chart review of all nonwhite patients who had received a biopsy-proven diagnosis of skin cancer at Drexel Dermatology during June 2008-June 2015.

Results: Squamous cell carcinoma (SCC) was the most commonly diagnosed skin cancer in black and Asian populations, and basal cell carcinoma was the most common skin cancer in Hispanics. Black persons exhibited the majority of their SCC lesions in sun-protected areas, particularly the anogenital area. On average, current smokers received skin cancer diagnoses 12.27 years earlier than former smokers and 9.36 years earlier than nonsmokers.

Limitations: Single-center design and interpractitioner variability of skin examination.

Conclusion: The importance of lesions in photoprotected areas in nonwhite individuals should not go overlooked. However, emphasis should also be placed on active examination of sun-protected areas in nonwhite persons and recognition of the relationship between human papillomavirus and genital SCC lesions. Smoking cessation should be integrated in dermatologic counseling of all patients. Interventions tailored to each of these ethnic groups are needed.
