Abnormal lymphocyte response to ultraviolet radiation in multiple skin cancer
- Finseninstitutet, Copenhagen (Denmark)
The lymphocyte response to ultraviolet radiation (254 nm) was investigated by two different methods in 29 unselected patients with multiple epidermal cancer. The ultraviolet-induced DNA synthesis was determined as the increase in incorporation of (/sup 3/H)thymidine in irradiated cells compared with non-irradiated cells after incubation for 2 h. The ultraviolet tolerance was measured as the ultraviolet dose necessary for 50% reduction in phytohemagglutinin-stimulated lymphocyte proliferation. Patients with both squamous cell differentiated tumours and basal cell carcinomas had very high ultraviolet-induced DNA synthesis values. The ultraviolet tolerance in patient lymphocytes was considerably lower than in control lymphocytes with the lowest values occurring in patients with clinical sun intolerance. These investigations may be of predictive value in skin carcinogenesis.
