A Five-Year Retrospective Analysis of Basal Cell Carcinoma: A Monocentric Study.

Abstract

ObjectiveOur aim in this study is to define the histopathological subtypes, body site distribution, and incidence rates of single or multiple of BCCs. The study is conducted on patients from a single institution in Istanbul which has a migrant-receiving population reflecting that of the country overall.MethodWe retrospectively analyzed data concerning 896 cases of BCC seen between 2014 and 2018. Data about patient demographics (age and sex), tumor diameter,its anatomic localization, histological type, presence of ulceration, lymphovascular/perineural invasion, and single or multiple tumor formations were retrieved from both the hospital’s automated system and archived records of the pathology clinic.ResultsOur univariate analysis showed that the patients’ age, tumor size, and tumor multicentricity were all significantly related to their gender (p=0.011, p=0.001, and p=0.021, respectively). Further, age, male gender, and tumor size were all significantly related to tumor multicentricity (p=0.003, p=0.021, and p=0.001, respectively). BCC was most commonly found in male, and the diameters of the BCC tumors were also larger in male patients. Multiple BCC was more frequently seen in older and male patients, and the tumors had larger diameters in these groups. The nodular type of BCC was the most frequently seen type in all age groups.ConclusionAs our study is the first BCC study that has the greatest number of cases in Turkey and as Istanbul reflects the population of Turkey, it is important for the data of BCC cases in Turkey.
