BACKGROUND: To compare the success rate of DNA flow cytometry in determining the DNA ploidy status in ectopic pregnancy and first trimester spontaneous abortion.
METHODS: Thirteen women with ectopic pregnancy (Group I) and 17 women with first trimester spontaneous abortion (Group II) were included into this study. DNA flow cytometric analysis was performed on all specimens. Aneuploidy was classified according to DNA index. The first trimester spontaneous abortions were also karyotyped after long-term culture of chronic villi. Student-t test and Fisher's exact test were used in statistical comparisons.
RESULTS: DNA aneuploidy was found in five women with ectopic pregnancy (38.5%) versus in 12 women with first trimester spontaneous abortion (70.6%), and it was comparable. A triploidy and a tetraploidy were detected in group I. Six tubal ectopic pregnancies were unruptured at laparatomy and four of them had aneuploid DNA content.
CONCLUSIONS: We believed that DNA flow cytometry was successful in determining the ploidy status of ectopic pregnancy and first trimester spontaneous abortion. In addition, it was interesting that ectopic pregnancies with aneuploid DNA content tended to be unruptured. However, this suggestion needs to be confirmed by further studies with larger numbers of cases.
