A person's risk factor for melanoma can be used to tailor self-examinations and surveillance programs, says a new study. The incidence of melanoma that occurs on the skin is increasing in predominantly European populations, and Australia's incidence is among the highest in the world.
Caroline G. Watts, M.P.H., of the University of Sydney, Australia, and coauthors examined clinical features associated with melanomas according to patient risk factors (many moles, history of previous melanoma and family history of melanoma) to improve the identification and treatment of those at higher risk.
The study included 2,727 patients with melanoma, of whom 1,052 (39 percent) were defined as higher risk because of family history, multiple primary melanomas or many moles. The most common risk factor in this group had many moles, followed by a personal history and a family history.
Also, higher-risk patients with many moles were more likely to have melanoma on the trunk, those with a family history were more likely to have melanomas on the limbs, and those with a personal history were more likely to have melanoma on the head and neck.
Limitations of the study include risk factors based on physician recall and patient medical records. The authors also did not assess the reliability or validity of the risk factor data.
"The results of our study suggest that a person's risk factor status might be used to tailor their surveillance program in terms of starting age and education about skin self-examination or more intensive surveillance," the study concludes.
The study is published in JAMA Dermatology.
