Summary
Parametrial involvement in endometrial cancer, identified by poor prognostic factors, significantly worsens patient outcomes. This spread reduces disease-free and overall survival rates, highlighting its critical impact on prognosis after radical hysterectomy.
Area of Science:
- Gynecologic Oncology
- Surgical Pathology
Background:
- Parametrial involvement is a critical prognostic factor in endometrial carcinoma.
- Understanding factors associated with parametrial spread is essential for refining treatment strategies and predicting patient outcomes.
Purpose of the Study:
- To identify clinicopathological factors associated with parametrial involvement in endometrial carcinoma patients.
- To evaluate the impact of parametrial involvement on the prognosis of patients undergoing radical hysterectomy.
Main Methods:
- An observational study categorizing 85 endometrial carcinoma patients based on the presence or absence of parametrial involvement.
- Descriptive and comparative analyses were conducted to determine associations between parametrial spread and various clinical, surgical, and pathological variables.
Main Results:
- Parametrial involvement was observed in 21% of patients (18/85).
- Significant associations with parametrial involvement included endometrioid subtype, grade 3, poor prognostic variants, deep myometrial invasion (>50%), serosal involvement, ovarian metastasis, positive peritoneal cytology, and lymph node metastasis.
- Patients with parametrial spread had significantly lower 5-year disease-free survival (50.8% vs. 74%) and overall survival (47.5% vs. 85.2%) compared to those without.
Conclusions:
- Histological factors of poor prognosis, such as tumors involving the uterine serosa, cervix, or spreading beyond the uterus, are associated with parametrial involvement.
- Parametrial involvement is an independent adverse prognostic factor, significantly reducing disease-free and overall survival and increasing recurrence risk in endometrial carcinoma patients treated with radical hysterectomy.
