GENE EXPRESSION PROFILE AND MOLECULAR-GENETIC ANALYSIS OF SYNOVIAL SARCOMA AND EWING’ SARCOMA/PNET
Abstract
The relationship between histological and immunohistochemical parameters of synovial sarcoma and Ewing’s sarcoma/PNET and the number of cells carrying the t(X;18)(p11.2;q11.2) translocation. Histological examination was carried out to study the cytotypical characteristics, types of structures of tumor growth, tumor spread and secondary dystrophic changes in the tumor. The tumor mitotic activity was assessed by determining the mitotic index. The presence of markers such as vimentine, desmin, SMA, Myf-4, MyoD1, S-100, CD57, bcl-2, CD99, cytokeratine AE1/AE3, cytokeratine 7, EMA, Synaptophysin, chromogranin and Ki67 was determined by immunohistochemical assay. Detection of translocations characteristic of synovial sarcoma and Ewing’s sarcoma/PNET was performed using chromogenic in situ hybridization. The study results showed the relationship between the histological and immunohistochemical parameters of synovial sarcoma and Ewing’s sarcoma/PNET and the percentage of tumor cells having specific t(X;18)(p11.2;q11.2) translocation.
