The multicentre south European study'Helios'I : Skin characteristics and sunburns in basal cell and squamous cell carcinomas of the skin.
The aim of this study was to investigate constitutional and environmental determinants of non-melanocytic skin cancer among different populations from south Europe.
Between 1989 and 1993 we interviewed incident cases and a random population sample of controls from five centres where a cancer registry was operating, whereas we selected a sample of hospital-based cases and controls from three other centres.
Controls were stratified according to the age and sex distribution of cases.
In all, 1549 cases of basal cell carcinoma (BCC), 228 of squamous cell carcinoma (SCC) and 1795 controls were interviewed.
Both cancers affected primarily sun-exposed sites such as face, head and neck, but the prevalence of BCC on the trunk was higher than for SCC.
Pigmentary traits such as hair and eye colour as well as tendency to sunburn were strong and independent indicators of risk for both BCC and SCC.
In SCC, adjusted odds ratios (ORs) ranged from 1.6 for fair hair colour to 12.5 for red hair.
Light-blonde hair entailed a risk of about 2 for BCC.
Pale eye colour was associated with a risk of 1.8 for SCC and 1.4 for BCC.
Subjects who always burn and never tan showed an adjusted OR of 2.7 for BCC and 2.0 for SCC.
A history of sunburns and a young age at first sunburn were associated with an increased risk for BCC only (OR 1.7).
Pigmentary traits and sun sensitivity of the skin confirmed their role as risk indicators. (...)
