Prognostic significance of argyrophilic nucleolar organizer region (AgNOR) in resected non-small cell lung cancer (NSCLC).
The expression of the nucleolar organizer regions (NORs) was quantified in paraffin sections of tumors and lymph node metastasis, by means of digital image analysis, in 75 patients with resected non-small cell lung cancer (NSCLC). Patients were divided in two groups: early stage (stages I and II) and advanced stage (stages IIIa, IIIb and IV). The prognostic significance of AgNOR expression was ...
متن کاملPrognostic significance of DNA ploidy pattern and nucleolar organizer regions (AgNOR) in colorectal carcinoma.
AIM To investigate the prognostic significance of DNA ploidy and silver stained nucleolar organizer regions (AgNOR), as well as their relation to the histological grade and Dukes' stages of colorectal carcinomas, and the relation of tumor cells proportion in the S-phase and Dukes' stage, histologic grade, DNA ploidy, or AgNOR count. METHODS DNA flow cytometric analysis and AgNOR were performe...
متن کامل[Clinical significance of proliferating cell nuclear antigen (PCNA) and argyrophilic nucleolar organizer region (AgNOR) in testicular tumors].
BACKGROUND Proliferative potential of testicular tumor was assessed by immunohistochemistry using anti-proliferating cell nuclear antigen (PCNA) monoclonal antibody and silver staining of argyrophilic nucleolar organizer region (AgNOR), and the results were compared with clinical course. METHODS Fourty-five patients with testicular tumor and 10 normal testicles were investigated. All specimen...
متن کاملThe role of argyrophilic nucleolar organizer region (AgNoR) study in cytological evalution of fluids, especially for detection of malignancy.
BACKGROUND Serous effusion smears reported as (suspicious for malignancy) pose problems in clinical management. Silver staining for argyrophilic nucleolar organizer regions (AgNOR) has proved useful in making a cytopathologic differential diagnosis between benign and malignant cells. Nucleolar organizer regions(NORs) are loops of DNA located in acrocentric chromosomes. These NORs are visualized...
متن کاملPrognostic significance of argyrophilic nucleolar organizer regions in esophageal carcinoma.
The argyrophilic nucleolar organizer region (AgNOR) of 100 cancer cells from biopsy specimens of esophageal squamous cell carcinomas in 98 surgically treated cases was examined, using a silver colloid staining technique on biopsy specimens. The number of AgNOR per nucleus (AgNOR number) was higher in the more advanced groups with regard to the length of the tumor (P less than 0.01), the depth o...
