The incidence and body site of skin cancers in the population groups of Astana, Kazakhstan.

Background And Aims: Data on cutaneous malignant melanoma (CMM), squamous cell carcinoma of the skin (SCC), and basal cell carcinoma (BCC) in populations consisting of multi-racial groups in the Commonwealth of Independent States are limited. Here, the main aim was to analyse the incidence and body site of these cancers in the population groups of Astana, Kazakhstan (2007-2016).

Methods: Annual age standardised incidences and body sites of BCC, SCC, and CMM in Astana's population, divided into "Kazakhs and other Turkic/Asian" and "Russian and other European/Caucasian" groups, were calculated from histologically confirmed cases reported to Astana Oncology Centre.

Non-Melanoma Skin Cancers at Sites of Previous Frostbite: Case Report and Review.

The association between ultraviolet radiation exposure and skin cancer is well established. Limited studies have reported an association between frostbite and the development of non-melanoma skin cancer but evidence for a proven link is insufficient and possible carcinogenic mechanisms have not been fully explored. In this report, 3 cases of non-melanoma skin cancer (1 case of basal cell carcinoma and 2 cases of squamous cell carcinoma of the skin) which developed at a site of previous frostbite caused by exposure to extremely cold temperatures in Astana, the capital city of Kazakhstan, are described.
