In a 2013 study published in this Journal, Dacosta Byfield et al. used MediCare data to extract reliable estimations of the incidence (I = 6.16) and prevalence (P = 10.31) rates of advanced keratinocyte skin cancer (aKSC) per 100,000 US population. These data unmask a considerable disease burden of aKSC (tumor stages ≥ 3) compared to the corresponding projected SEER predictions in 2019 of all invasive cases (tumor stages ≥ 1). According to its incidence, aKSC ranks 19th out of 29 major SEER

registered neoplasms and has an average disease duration of 1.67 years, which is the second shortest disease duration next only to pancreatic carcinoma. Furthermore, in support of the high disease aggressiveness of aKSC and using a calibration approach, we calculated a mortality estimate of 4.64 per 100,000 and a 5-year survival rate of 21.8% for this tumor, which corresponds to positions of 13th and 5th out of 29 cancers among the SEER tracked malignancies, respectively. Taken together, these data indicate a considerable disease burden and biologic aggressiveness of aKSC.
