A systematic review of worldwide incidence of nonmelanoma skin cancer

Abstract

SummaryBackground Nonmelanoma skin cancer (NMSC) is the most common cancer affecting white-skinned individuals and the incidence is increasing worldwide. Objectives This systematic review brings together 75 studies conducted over the past half century to look at geographical variations and trends worldwide in NMSC, and specifically incidence data are compared with recent U.K. cancer registry data. Methods Following the development of a comprehensive search strategy, an assessment tool was adapted to look at the methodological quality of the eligible studies.Results Most of the studies focused on white populations in Europe, the U.S.A. and Australia; however, limited data were available for other skin types in regions such as Africa. Worldwide the incidence for NMSC varies widely with the highest rates in Australia [> 1000 ⁄100 000 person-years for basal cell carcinoma (BCC)] and the lowest rates in parts of Africa (< 1 ⁄100 000 person-years for BCC). The average incidence rates in England were 76AE21 ⁄100 000 personyears and 22AE65 ⁄100 000 person-years for BCC and squamous cell carcinoma (SCC), respectively, with highest rates in the South-West of England (121AE29 ⁄100 000 person-years for BCC and 33AE02 ⁄100 000 person-years for SCC) and lowest rates by far in London (0AE24 ⁄100 000 person-years for BCC and 14AE98 ⁄100 000 person-years for SCC). The incidence rates in the U.K. appear to be increasing at a greater rate when compared with the rest of Europe. Conclusions NMSC is an increasing problem for health care services worldwide. This review highlights a requirement for prevention studies in this area and the issues surrounding incomplete NMSC registration. Registration standards of NMSC should be improved to the level of other invasive disease.

Preventing Skin Cancer Through Reduction of Indoor Tanning

“…1,3,12,13 There are an estimated 3.5 million cases of basal and squamous cell carcinomas in the U.S. annually, and the incidence is increasing worldwide. 14,15 Two recent studies provide estimates of the number of skin cancers that may be caused by indoor tanning each year; more than 170,000 cases of squamous and basal cell carcinomas of the skin may be due to indoor tanning in the U.S. annually, and more than 3400 cases of melanoma may be due to indoor tanning in Europe. 16,17 Melanoma causes more deaths than any other skin cancer, and its incidence is increasing, particularly among non-Hispanic whites and women; increases have also been noted among all tumor thicknesses.…”

Nuevos modelos experimentales para el estudio de la homeostasis y la enfermedad cutánea

“…El más común de todos es el BCC, que da cuenta del ~75% de todos los cánceres de piel no melanoma 52 . La incidencia de cáncer cutáneo va aumentando progresivamente; ello es debido al deterioro de la capa de ozono y a los hábitos vacacionales de exposición solar de la piel, que se han extendido a una gran parte de la población.…”

“…An estimated 3.5 million new cases are diagnosed every year in the United States alone and about 580,000 in England, Europe, and Australia 1 , 2 . NMSCs occur most commonly in the middle‐aged and older populations.…”
