Prognostic significance of cell DNA content in early-stage ovarian cancer (FIGO stages I and II/A) by means of automatic image cytometry.
Paraffin-embedded material from 69 patients with epithelial ovarian cancer FIGO stages I and II/A (including 21 patients with borderline carcinoma) was studied with automatic DNA image cytometry. Univariate analysis indicated a significant difference in survival based on the presence of nuclei with high DNA content (higher than 5 C). A group of patients with less than 0.2% cells with high DNA content had a 6-year survival of 87%, whereas in a group of patients with more than 0.2% of such cells, 6-year survival was 49%. This parameter remained significant when used in a group of stage I/a and I/b patients. Statistical analysis of diploid vs. non-diploid tumors also showed significant difference in survival. Separate analysis of 48 invasive ovarian cancers indicated that ploidy, the percentage of cells with high DNA content and tumor stage (stage I/a + b vs. stages I/c + II/a) reached significance for survival, whereas grading did not. In addition, comparison of clinical stage, grading, ploidy and the percentage of cells exceeding 5 C with a threshold at 0.2% by means of a multivariate analysis (Cox regression model) showed that only the percentage of cells exceeding 5 C remained statistically significant.
