5. Conclusion
In summary, we found that age, histological type, FIGO stage, number of examined lymph nodes, and number of positive lymph nodes were independent prognostic factors of CSS in EOC patients with PE treatment. We successfully developed a predictive nomogram of 3-year and 5-year CSS which has been demonstrated to present less bias, superior accuracy, and great clinical value. This high-quality nomogram could provide an important reference for individualized therapeutic suggestions and follow-up strategies.
