Abstract

Nuclear pseudoinclusions (NPIs) are classically found in papillary thyroid carcinoma and meningioma. Although NPIs have been described in melanocytic lesions, there is no systematic analysis of potential relationship between NPIs and other clinicopathological characteristics of melanoma. We examined the presence of NPIs in H&E-stained tissue sections form 96 melanomas and analyzed statistical associations with important clinicopathological parameters and tissue immunoreactivity for selected proteins involved in epithelial-mesenchymal transition (SPARC, N-cadherin), cell adhesion and mobility (ALCAM, ADAM-10), regulation of mitosis (PLK1), cell survival (FOXP1) and functioning of Golgi apparatus (GOLPH3, GP73). NPIs were observed in 20% of melanomas and their presence correlated with high mitotic rate and ulceration of the tumor, but not with Breslow thickness, histologic type, or presence of metastases. We observed a significant correlation with shorter cancer-specific survival, but not disease-free survival. Presence of NPIs was related to high expression of GOLPH3 in melanoma cells, whereas their absence was linked to enhanced immunoreactivity of GOLPH3 in tumor-associated macrophages. NPIs are not an uncommon finding in skin melanoma and their diagnostic and prognostic utility could be helpful in the daily routine histopathological practice. The possible explanation of NPI generation is associated with enhanced activity of Golgi apparatus in melanoma cells.

Abstract in PolishGłównym wynikiem pracy jest weryfikacja biomarkera GOLPH3 pod kątem skuteczności w przewidywaniu przeżycia całkowitego i okresu wolnego od choroby nowotworowej. Wykorzystano modele analizy przeżycia do budowy modelu Coxa. Trzeba przyznać że sam GOLPH3 nie jest zbyt silnym markerem prognostycznym. Ale ponieważ jest to nowy marker to i takie (pół negatywne) wyniki są interesujące.
