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.
Morphology and deoxyribonucleic acid (DNA) content of endometrial cancer nuclei under progestogen treatment are reported. 12 endometrial cancers were observed before and during treatment. 8 were well-differentiated and displayed on objective response. The response was characterized by a volumetric reduction of the nucleus and the disappearance of tetraploid nuclei. DNA content remained diploid or near-diploid. Reduction of nuclear non-DNA proteins in endometrial cancers under progestogen treatment is suggested.
