Abstract

The objective of this paper is to answer the clinical question whether the location of the lesion in an individual patient with actinic keratosis (AK) influences the absolute risk of the development of skin cancer. Between 0.025% and 16% of AK lesions advance towards squamous cell carcinoma per year. It is not well known whether this risk differs between locations on the body. A systematic search of available literature resulted in seven articles of which the two highest scoring on relevance and validity were selected. These two studies indicate that the absolute risk on the development of skin cancer in patients with AK differs between locations of the lesion and that time to progression from AK to squamous cell carcinoma is not different among the locations of the lesions. However, both studies have very limited sample sizes.
