A recently published cohort study of 483 individuals with Li-Fraumeni Syndrome (LFS) identified 113 skin cancers. The cumulative incidence of a diagnosis of any skin cancer was 36.3% by the age of 70. Specifically for melanoma, the median age at diagnosis was 42 with a 7-fold increased incidence (SIR 7.28, 95% CI 4.50-11.13) compared with the general population and a risk to age 70 of almost 15% (Figure 1). The incidence of other types of skin cancer (i.e., squamous cell and basal cell carcinoma) were similar to those in the general population.

Currently, there is an international study being conducted to learn more about LFS, called the LiftUp Study – to learn more or participate in these efforts directly, visit https://liftupstudy.org.
