Correlation of Molecular-Genetic and Morphological Markers of Rare Salivary Gland Tumors
Šteiner, Petr ; Skálová, Alena (advisor) ; Laco, Jan (referee) ; Šíma, Radek (referee)
Thesis deals with relationship between histomorphological and molecular-genetic findings of selected salivary gland tumors. Author, as a molecular-cytogeneticist mainly focused on detection of tumor-specific translocations of the salivary gland tumors which can serve as differential diagnostic markers. The thesis is composed as a commented files of authors own publications, and it is divided into four parts. First part deepens the knowledge of salivary adenoid cystic carcinoma. It was proved, that t(6;9)(q22-23;p23-24) resulting in fusion of transcription factors MYB-NFIB, or more rarely t(8;9) resulting in MYBL1-NFIB fusion represent robust differential diagnostic marker of adenoid cystic carcinoma. Further it was proved, that the 1p36 deletion can serve as an unfavorable prognostic indicator of adenoid cystic carcinoma, as the patients with 1p36 deletion had significantly lower survival. Second part summarizes new developments about mammary analogue secretory carcinoma (MASC), which was described by our group as a new salivary tumor entity characterized by translocation t(12;15)(p13;q25) resulting in ETV6-NTRK3 fusion. Another novel observation is a discovery of ETV6-RET fusion in a subset of MASC cases. Further, the first two MASCs of nasal mucosa origin have been described. Third part consists...
