A dose-response curve for sun exposure and basal cell carcinoma.

摘要: A population-based case-control study of sun exposure and basal cell carcinoma (BCC) was conducted in Western Australia 1988. Its aim to examine the relationship between risk BCC amount pattern exposure. This report deals with The odds ratios (ORs) for on head neck limbs decreased increasing total exposure, whereas opposite observed less heavily exposed trunk, highest OR those greatest In an analysis all body sites together which hours specific site treated as a continuous variable, initial rise seen peak 1.4 at about 35,000 hr followed by fall. contrast these site-specific patterns, lifetime accumulated whole showed no appreciable association either or working days only. Risk positively associated non-working days, however, higher than baseline categories around 1.7. There significant interaction ability tan occupational increased who tanned well but not poorly. is consistent other observations indicate that beyond certain level does increase further.
