A Statistical Study of Cutaneous Basal Cell Carcinoma and Squamous Cell Carcinoma in Gwangju City and Chonnam Province (2006~2010) / 대한피부과학회지

ABSTRACT

BACKGROUND: The incidence of cutaneous malignant tumors has been continuously increasing worldwide. OBJECTIVE: The purpose of this study was to analyze recent trends in the incidence of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) in patients from Gwangju City and Chonnam Province. METHODS: We reviewed clinical data and histopathological reports of 82 cases of BCC and 60 cases of SCC in outpatients who had visited the department of dermatology at Chosun University Hospital between 2006 and 2010. RESULTS: The male-female ratio was 0.611 in patients with BCC and 0.871 in patients with SCC. The most frequent age group was the eighth decade (42% BCC and 67% SCC). Mean patient ages were 65.1 years and 67.8 years, respectively. The most common involved site was the face (90.2% BCC and 78.3% SCC), particularly the cheek. More skin cancers were found on the left than the right side of head and neck area in male automobile drivers only. The most frequent histological BCC subtype was the nodulocystic type (59.7%), followed by the pigmented (12.1%), and adenoid type (9.7%). The most frequent histological pattern of SCC was the well-differentiated type (66.6%). Development of BCC (61.3%) was more frequent than that of SCC in sun-exposed areas. CONCLUSION: Our data were similar to those previously reported. In our study, no difference in demographic variables such as age, gender or residence were found between patients with BCC and SCC. Additionally, no differences were observed in the incidence of BCC or SCC among the other variables. Further cohort studies that include cumulative lifetime sun exposure and a large sample size are needed.
