Introduction: Describe factors associated with parametrial involvement, and how these factors modify the prognosis of patients with endometrial carcinoma treated with radical hysterectomy. Methods: Observational study in which categorized patients according to those with and without parametrial involvement. A descriptive analysis and comparative analysis were performed for associations between parametrial spread and clinical, surgical, and pathology variables. Results: We analyzed 85 patients, which 18 (21%) had parametrial involvement. Pathology factors associated with parametrial involvement were the endometrioid subtype, grade 3, and variants of poor prognosis (odds ratio (OR) 3.41, 95% CI 1.09-10.64; P = 0.035), myometrial invasion of over 50% (OR 7.76, 95% CI 1.65-36.44; P = 0.009), serosal involvement (OR 17.07, 95% CI 3.87-75.35; P < 0.001), ovarian metastasis (OR 5.15, 95% CI 1.36-19.46; P = 0.016), positive peritoneal cytology (OR 3.9, 95% CI 1.04-14.77; P = 0.044), and lymph node metastasis (OR 3.4; 95% CI 1.16-9.97; P = 0.026). Five-year disease-free survival was 74% (95% CI 57.4-85.4) for the group without parametrial spread and 50.8% (95% CI 22.7-73.4) for the group with parametrial spread (P = 0.001). Similarly, 5-year overall survival was 85.2% (95% CI 67.9-93.6) for the group without parametrial spread and 47.5% (95% CI 8.1-80.2) for the group with parametrial spread (P = 0.002). Conclusion: Factors associated with parametrial involvement were histologies of poor prognosis, tumors affecting uterine serosa, cervix, or spread beyond the uterus. Additionally, parametrial involvement directly affects prognosis by reducing overall survival, disease-free survival and increasing odds for recurrence. [ABSTRACT FROM AUTHOR] |
