title: Morphology and DNA content of endometrial cancer nuclei under progestogen treatment.
abstract: Twelve endometrial cancers have been observed before and during progestogen treatment. Eight were well-differentiated and displayed an objective response. It was essentially characterized by a volumetric reduction of the nucleus and the disappearance of tetraploid nuclei. The DNA content remained diploid or near-diploid. Reduction of nuclear non DNA proteins under hormonal treatment is suggested.
