Abstract
A microspectrophotometric study of the DNA content was undertaken in seven cases of gastric carcinoma in comparison with the normal stomach epithelial tissue. The results are summarized in Fig. 1 and Table I. The cells of the normal epithelial tissue showed the DNA content in basic value-2n with a limited degree of variation from cell to cell. Carcinoma cells showed a much larger scatter in distribution of DNA values from cell to cell than the normal cells and four out of seven cases showed DNA values lying around a triploid range. Generally, the DNA content of gastric carcinomas here considered tends to correspond to the stem-line chromosome number of these tumors.
