The stereological estimate of mean nuclear volume is an objective and reproducible method of measurement of nuclear size in terms of absolute volume. We have used this method to study carcinomas of the ampulla of Vater. Our study includes 21 cases--five papillary and 16 intestinal--all treated by the same surgical procedure. The volume-weighted mean nuclear volume (nuclear nu v) and the mean nuclear area were calculated. The mean volumes of nuclear nu v were significantly different (P less than 0.01) between the papillary and intestinal carcinomas, but no differences were found between normal mucosa and papillary carcinoma. The variance was significantly larger in the intestinal group than the papillary and normal groups. The nuclear nu v showed a significant association with survival, larger nuclear nu v (greater than 150 microns 3) being associated with a lower survival rate.

D002467 Cell Nucleus Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed) Cell Nuclei,Nuclei, Cell,Nucleus, Cell
