BACKGROUND: The aim of this study was to retrospectively analyze all the cases of BCC histologically diagnosed in the Cutaneous Tumor Center of Dermatology of Bologna University, in a period between 1990 and 2014.
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 basal cell carcinoma (BCCs), the demographic features of patients and the characteristics of BCCs with statistically significant correlations.
RESULTS: During the investigated 25 years, 8557 BCCs were collected in 7297 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 an 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.
