Sažetak
The incidence and prevalence of premalignant and malignant skin lesions including squamous cell carcinoma (SCC) of the skin are increasing worldwide. The aim of the study was to determine TP53, Bcl-2 and growth hormone receptor (GHR) expression in SCC and to investigate relative importance of these proto-oncogenes in its biological behavior. Expression of TP53, Bcl-2 and GHR was determined by immunohistochemistry in 27 SCC specimens and adjacent perilesional skin. The relative proportion of immunoreactive cells was counted with semiquantitative method. TP53 positivity was detected in 24 (89%), Bcl-2 in 18 (67%) and GHR in 25 (93%) of 27 SCC specimens investigated. In comparison with perilesional skin, TP53 and GHR positivity was significantly increased, and Bcl-2 positivity significantly decreased in SCC. Increased TP53 expression in SCC lesions implies that Tp53 mutation is an early and crucial event in its development. Increased GHR expression suggests a role of growth hormone in the development of SCC.
