The evolution of national skin cancer registration: Improving our understanding of skin cancers through use of national registry data

This thesis uses national registry data from UK and the Netherlands to report the incidence, demographics, survival and trends of skin cancers. We develop and validate a technique to improve basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) reporting. We then report the incidence of BCC and cSCC for the first time in the UK. We developed and validated a method to identify metastatic cSCC using national registry data and report the first national incidence of metastatic cSCC. A similar technique is then used to report the incidence of metastatic cSCC in the Netherlands. Finally we use these datasets to analyse current staging methods for cSCC and their predictive ability.
