Description
Summary:Objective. The aim of this study was to analyze the prognostic significance of DNA ploidy in patients with endometrial cancer. Methods. Between October 1988 and January 1997, DNA ploidy was determined prospectively in 208 women who were staged surgically by a standard protocol that included pelvic and para-aortic lymphadenectomy. Median follow-up was 48 months. Results. Diploid tumors were identified in 154 (74%) patients and aneuploid tumors in 54 (26%). Patients with aneuploid tumors had a significantly higher prevalence of metastases to the cervix, adnexa, and omentum, malignant pelvic cytology, and advanced surgical stage. Patients with aneuploid tumors had a 4.5 times higher prevalence of pelvic lymph node metastases and a 5.8 times higher prevalence of para-aortic lymph node metastases. A significantly higher proportion of patients with aneuploid tumors was diagnosed with recurrent or progressive endometrial cancer (22.2 versus 6.5%, P = 0.002). Patients with aneuploid tumors had a significantly lower rate of survival from cancer death (P = 0.038) with 83% versus 94% surviving 5 years. Conclusion. Patients with aneuploid tumors are at high risk for lymph node metastases and should be surgically staged, including pelvic and para-aortic lymphadenectomy. Aneuploidy confers a risk for endometrial cancer death and these patients should be candidates for clinical trials evaluating treatment following surgery.
