DNA Ploidy Study in Esophageal Cancers

The values of DNA content in 47 patients with esophageal cancers were evaluated in comparison with clinic o-pathological factors and their prognoses. DNA ploidy profiles were analyzed from paraffin-embedded preparates. The diploid tumors accounted for 41.1% in this series. Aggressive cancer extension was not necessarily seen in the aneuploid tumors as compared with the diploid tumors. One must be aware that some of the diploid tumors indicate worse prognosis.
