[Topoisomerase IIa expression in correlation with clinical and morphological parameters and proliferation (based on argyrophilic proteins of nucleolar organizer regions and Ki-67 antigen) in lung adenocarcinoma].

Investigated topoisomerase IIalpha (TopoII alpha), argyrophilic proteins associated with nucleolar organizer regions (Ag-NOR) and antigen Ki-67 in lung adenocarcinoma. Defined tumor with low and high TopoII alpha, Ag-NOR and Ki-67. TopoII alpha had a relationship with clinical and morphological parameters (greatest dimension, tumor differentiation) and proliferation markers (Ag-NOR, Ki-67) . Survival of patients with lung adenocarcinoma with low content of TopoII alpha is better as compared with high content of TopoII alpha. Survival of patients with lung adenocarcinoma depends on the mutual content of TopoII alpha and clinical and morphological parameters (value T, greatest dimension, value N, stage, tumor differentiation), proliferation markers (Ag-NOR). TopoII alpha content in lung adenocarcinoma is an independent prognostic factor. Mutual research of TopoII alpha with clinical and morphological parameters and Ag-NOR has prognostic value in lung adenocarcinoma.
