title: [Fluorescence cytophotometric DNA studies of Ewing and osteosarcomas].
abstract: The single-cell fluorescence cytometric data presented in this study basing on measurements on 6 osseous Ewing's-Sarcoma and 17 classical osteosarcoma are showing a mirrorlike behaviour to cytological and histological appearance. The cellular monotony in Ewing's-Sarcoma and the polymorphic appearance of osteosarcoma are represented by typical aneuploid DNA-histograms. Ewing's-Sarcoma histogram's show a large peak between the diploid and tetraploid region and little deviation to the octoploid value. The conventional osteosarcomas are characterised by a very polyploid and changeable DNA-histogram with variable blocks and peaks and deviation up to 34c. Special trends in the subtypes are remarkable, but depend on further investigations. DNA-measurements support objectivization of histological appearance on the one hand and the controlling of therapeutical responses on the other hand.
