Abstract: | Microspectrophotometric measurement of the cellular DNA content of 73 cervical carcinoma specimens was carried out. The tumor was diploid in 7 cases, tetraploid in 2 and aneuploid in 64. The cases could be divided into hyperploid and hypoploid groups using the DNA index of 1.5 as demarcation. The DNA content was found to be closely related to the histologic types and mitotic figures of the tumors. Hyperploidy was more frequently seen in large-cell carcinoma and hypoploidy in small-cell varieties. |
