BACKGROUND: PC cell-derived growth factor (PCDGF) is an autocrine growth factor originally purified from the highly tumorigenic teratoma PC cell line. It participates in tumorigenesis and tumour progression through upregulation of cyclin D1. To date, there has been no report on the role of PCDGF in skin cancer, to our knowledge.
AIM: To investigate the expression of PCDGF and cyclin D1 in basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and seborrhoeic keratosis (SK), and their relationship with the clinicopathological parameters of SCC.
METHODS: Immunohistochemical expression of PCDGF and cyclin D1 was examined in 42 SCC, 30 BCC and 20 SK tissues.
RESULTS: PCDGF and cyclin D1 were overexpressed in SCC or BCC tissues compared with normal skin or SK, and their expressions were significantly higher in SCC than in BCC. Moreover, positive expression of PCDGF and cyclin D1 was significantly correlated with depth of invasion and metastasis of SCC. There was significant correlation between PCDGF and cyclin D1 expression in SCC.
CONCLUSIONS: Expression of PCDGF and cyclin D1 plays an important role in the tumorigenesis of BCC and SCC. Abnormal expression of PCDGF and Cyclin D1 may be related to invasion and metastasis of SCC.
