BACKGROUND: Basal cell carcinoma (BCC) has a rising incidence worldwide. The aim was to evaluate incidence trend, demographic features and risk factors for BCC in the area of Bologna in northern-central Italy.
METHODS: All the consecutive histopathologically diagnosed BCCs at the Dermatology of the Bologna University from 1990 to 2014 were retrospectively reviewed. We evaluated the absolute number of BCCs, the demographic features of patients and the characteristics of BCCs with statistically significant correlations.
RESULTS: During the investigated 25 years, 8,557 BCCs were collected in 7,297 patients. We observed that the incidence of this cancer, after stabilizing around a plateau of 400 cases/year in 2005, progressively increased onwards reaching a maximum of cases (821) in 2014 (+105.25%), with a 8.32% mean increase per year in those last 9 years. Moreover, we found a significant correlation (p<0.01%) between gender and the onset of BCC, between the anatomic location and the occurrence of the tumor, between the onset of recurrent or new BCCs and sun exposure.
CONCLUSIONS: The present study collects the largest series in the Italian literature focused on demographic features and characteristics of BCC, highlights its higher increasing incidence in Bologna and the need to improve preventive strategies to stem the epidemic diagnosis of BCC.
