Summary

This summary is machine-generated.

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.
