Expression of antiapoptotic protein survivin in malignant melanoma

Abstract: We examined the expression of potential tumor marker survivin by immunohistochemical staining using antisurvivin antibody (DAKO, Clone 12C4) in a panel of 25 malignant melanomas. In each section, we assessed the percentage of positively stained tumor cells, the intensity of staining and its subcellular localization. Survivin was present in 23 out of 25 cases (92%). Nuclear staining was found in 2 of these 23 cases (8.7%) only, while cytoplasmic staining only was seen in 3 of them (13%). The combined nuclear as well as cytoplasmic localization of survivin was demonstrated in 18 out of 23 cases (78.3%). In 2 cases revealing nuclear staining only, the worse histological features were more pronounced than in 3 cases with cytoplasmic staining only. Our results suggest that nuclear positivity of survivin may correlate with the degree of malignancy. In addition, we conclude that overexpression of survivin involved in the pathogenesis of melanoma represents an important diagnostic marker.
