Table 2 shows a comparison of the G0/G1, S phase, G2/M stage, aneuploidy cell ratio (sample flow cytometric analysis results for aneuploidy cell ratio in cases of serous cystadenoma (Figure 1) and serous cystadenocarcinoma (Figure 2)), S phase, proliferative index, and annexin V apoptotic index-positive cell ratio (Figure 3, sample flow cytometric analysis result for annexin V apoptotic index in cases of serous cystadenoma (a) and serous cystadenocarcinoma (b)) in the serous cystadenoma and serous ovarian cystadenocarcinoma groups detected by flow cytometry. This evidence concerns the gene ANXA5 and serous cystadenocarcinoma.
