The relationship among cytological features, DNA content, and degree of histological differentiation of cervical adenocarcinoma was investigated in an attempt to discover a more accurate means of screening for this cancer. In highly differentiated adenocarcinoma (so-called adenoma malignum), the nuclei were only somewhat more irregular in size and shape than those of normal columnar epithelial cells. The cells were arranged in slightly multilayered clusters. The cells of well-differentiated adenocarcinoma were usually columnar in shape, and they exfoliated side by side in clusters. In moderately differentiated adenocarcinoma, solitary cells with markedly atypical nuclei were combined with multilayered cell clusters. The cells from poorly differentiated adenocarcinoma were roundish, occurred as solitary cells or irregularly overlapping cell clusters, and showed markedly atypical nuclei. As the degree of histological differentiation decreased, as determined by measurement of the DNA content of the cells, the DNA distribution covered a wider range in terms of ploidy, and the number of cells exceeding tetraploid DNA content increased.

SummaryObjective. This study analyzes whether concomitant raloxifene (RLX) or bisphosphonates (BP) plus eldecalcitol (ELD) has excessive suppressive effects on a bone resorption marker during the first 6 months of treatment in postmenopausal women in real-world setting. Methods. 285 postmenopausal osteoporotic patients who had been treated with RLX or BP plus ELD were evaluated the bone resorption marker, serum tartrate resistant acid phosphatase-5b (TRACP-5b), during the first 6 months of treatment. Results. In drug-naïve group (not received osteoporosis medications before the administration, n=70), the concomitant RLX or BP with ELD significantly decreased levels of TRACP-5b without severe suppression. In vitamin D switch group [RLX or BP plus alfacalcidol (ALF) and then switched to RLX or BP plus ELD, n=215], the replacing ALF with ELD further and significantly decreased TRACP-5b and tertile analyses based on baseline values were significantly decreased far more in the highest, compared with the lowest tertile in the ELD+RLX and ELD+BP groups. Conclusion. ELD combined with RLX or BP administered for 6 months to postmenopausal women with osteoporosis who were drug-naïve or who had switched medications significantly reduced and maintained TRACP-5b values within the reference range.
