The incidence of cutaneous malignant melanoma has steadily increased over the past 50 years in predominately fair‐skinned populations. This increase is reported to have leveled off recently in several Northern and Western European countries, Australia, New Zealand and in North America. We studied the global patterns and time trends in incidence of melanoma by country and sex, with a focus on and age‐ and cohort‐specific variations. We analyzed the incidence data from 39 population‐based cancer registries, examining all‐ages and age‐truncated standardized incidence rates of melanoma, estimating the annual percentage change and incidence rate ratios from age‐period‐cohort models. Incidence rates of melanoma continue to rise in most European countries (primarily Southern and Eastern Europe), whereas in Australia, New Zealand, the U.S., Canada, Israel and Norway, rates have become rather stable in recent years. Indications of a stabilization or decreasing trend were observed mainly in the youngest age group (25–44 years). Rates have been rising steadily in generations born up to the end of the 1940s, followed by a stabilization or decline in rates for more recently born cohorts in Australia, New Zealand, the U.S., Canada and Norway. In addition to the birth cohort effect, there was a suggestion of a period‐related influence on melanoma trends in certain populations. Although our findings provide support that primary and secondary prevention can halt and reverse the observed increasing burden of melanoma, they also indicate that those prevention measures require further endorsement in many countries.

Non-melanoma skin cancer (NMSC) is the most common malignancy, whose public health significance is often unrecognized. This analysis has two objectives: first, to provide up-to-date incidence estimates by sex, age group, histological type, and body site; and second, to study the impact of skin cancer screening. The impact of screening on NMSC incidence in Schleswig-Holstein, Germany, is analyzed by comparing four time periods of different screening settings (no screening (1998-2000), pilot project (Skin Cancer Research to Provide Evidence for Effectiveness of Screening in Northern Germany, SCREEN, 2003-2004), after SCREEN (2004-2008), and nation-wide skin cancer screening (2008-2010)) to a reference region (Saarland, Germany). Age-standardized (Europe) NMSC incidence was 119/100,000 for women and 145/100,000 for men in the most recent screening period in Schleswig-Holstein (2008-2010). During implementation of SCREEN (2003-2004), incidence increased from 81.5/100,000 to 111.5/100,000 (1998-2000) by 47% for women and 34% for men. All age groups in women were affected by the increase, but increases for men were mostly limited to the older age groups. Incidence in Saarland first increased slowly, but increased steeply with the introduction of the nation-wide skin cancer screening in 2008 (+47% for women and +40% for men, reference 2004-2008). Observed changes are most likely attributed to screening activities.

Summary Actinic keratoses (AK) are common lesions in light‐skinned individuals that can potentially progress to cutaneous squamous cell carcinoma (cSCC). Both conditions may be associated with significant morbidity and constitute a major disease burden, especially among the elderly. To establish an evidence‐based framework for clinical decision making, the guideline “actinic keratosis and cutaneous squamous cell carcinoma” was developed using the highest level of methodology (S3) according to regulations issued by the Association of Scientific Medical Societies in Germany (AWMF). The guideline is aimed at dermatologists, general practitioners, ENT specialists, surgeons, oncologists, radiologists and radiation oncologists in hospitals and office‐based settings as well as other medical specialties involved in the diagnosis and treatment of patients with AK and cSCC. The guideline is also aimed at affected patients, their relatives, policy makers and insurance funds. In the first part, we will address aspects relating to diagnosis, interventions for AK, care structures and quality‐of‐care indicators.

a population-based skin cancer screening project was conducted in SchleswigHolstein, Germany. In total, 360,288 individuals aged !20 years were screened by means of a whole-body examination. In this report, the authors compare trends in melanoma mortality in Schleswig-Holstein with those in all adjacent regions, none of which had population-based skin cancer screening. METHODS: Trends in melanoma mortality rates for Schleswig-Holstein and the adjacent regions (Denmark and the German federal states of Mecklenburg-Vorpommern, Hamburg, and Lower Saxony) and in Germany excluding Schleswig-Holstein were compared. Log-linear regression was used to assess mortality trends. RESULTS: In Schleswig-Holstein during the pre skin cancer screening period (1998)(1999), the age-standardized melanoma mortality rate (World standard population) was 1.9 per 100,000 for men and 1.4 per 100,000 for women. Melanoma mortality declined by 47% to 1.0 per 100,000 men and by 49% to 0.7 per 100,000 women by 2008/2009. The annual percentage change in the most recent 10-year period (2000-2009) was À7.5% (95% confidence interval, À14.0, À0.5) for men and À7.1% (95% confidence interval, À10.5, À2.9) for women. In each of the 4 adjacent regions and in the rest of Germany, mortality rates were stable, and the decline in Schleswig-Holstein was significantly different from the changes observed in all of the other areas studied. CONCLUSIONS: The current data represent strong evidence, but not absolute proof, that the skin cancer screening program produced a reduction in melanoma mortality in Schleswig-Holstein.
