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 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...
متن کاملApplication of AgNOR (Argyrophilic Nucleolar Organizer Regions) Staining in Distinction of Non Neoplastic and Neoplastic Endometrial Lesions
Study of AgNOR has been identified as a reliable indicator of cell proliferation and in turn, allows a clear distinction between benign, premalignant, and malignant epithelial changes. The aim of this study was to analyze and evaluate the application of AgNOR method as diagnostic tool in non-neoplastic and neoplastic lesions of endometrium. The study included evaluation of AgNOR staining on a t...
متن کاملChanges in histologic grade and argyrophilic nucleolar organizer regions during progression of prostate cancer.
To determine the changes in histologic features during the course of prostate cancer under long-term endocrine therapy, histologic grade and argyrophilic nucleolar organizer regions (AgNORs) were examined in specimens before treatment, at relapse, and at cancer death. A total of 29 patients who had received therapy and died of prostate cancer were evaluated. Among the 29 cases, biopsy tissues b...
