Argyrophilic Nucleolar Organizer Regions (AgNORs) and Degree of Malignancy in Adenocarcinomas of The Lung Less than 2.0cm in Size
Argyrophilic stain for nucleolar organizer regions (AgNORs) to assess proliferative activity and malignant intensity was used in 21 cases with resected adenocarcinomas of the lung less than 2.0cm in size. The mean number of AgNOR dots per nucleus (AgNOR count) of tumor cells was 5.60, of infiltratin...
