Introduction. Nonmelanoma skin cancers in the literature are mainly related
to basal cell and squamous cell skin carcinoma. Objective. The aim of the
study was to determine the trend in the incidence of histological types of
nonmelanoma skin cancers in the population of the city of Belgrade from 1999
to 2011. Methods. From the Serbian National Cancer Registry we extracted all
recorded cases of skin cancer in Belgrade from January 1st 1999 to December
31st 2011. Incidence rates were standardized by the method of direct
standardization with the world population as the standard population. Trends
and annual percentage change (APC) of incidence rate were calculated by
performing joinpoint regression analyses. Results. Incidence rate of
nonmelanoma skin cancer showed significantly increasing trend between 1999
and 2006 with APC of 8.6% (95% CI: 5.6-11.7), basal cell carcinoma increased
with APC of 8.4% (95% CI: 5.2-11.6) and squamous cell skin carcinoma with APC
of 9.33% (95% CI: 5.7-13.1). The incidence increased with age for both men
and women, especially after the age of 60. Conclusion. Our results showed a
continuously increasing incidence trend of both basal cell and squamous cell
skin carcinomas in the population of the city of Belgrade between 1999 and
2011. Adequate primary and secondary prevention would certainly be successful
in reducing this type of cancer in the future.
