Summary
Accurate staging of endometrial cancer is crucial. Postoperative examination revealed extrauterine lesions in 35% of clinical stage II cases, necessitating surgical adjustments for optimal treatment.
Area of Science:
- Gynecologic Oncology
- Surgical Pathology
Background:
- Accurate staging of endometrial carcinoma is critical for effective treatment planning.
- Staging errors can lead to treatment failure in patients with malignant diseases.
Purpose of the Study:
- To investigate the actual postoperative progression of endometrial carcinoma in patients initially classified as clinical stage II.
- To determine the incidence and sites of extrauterine lesions in these patients.
Main Methods:
- Retrospective analysis of twenty patients with clinical stage II endometrial carcinoma.
- Postoperative examination including surgical exploration to identify extrauterine lesions.
Main Results:
- Extrauterine lesions were identified in 7 out of 20 patients (35%).
- These included high-grade endometrioid cancers and uterine papillary serous carcinomas (UPSC) with spread to parametria, pelvic lymph nodes, periaortic lymph nodes, and omentum.
- Patterns of spread in high-malignancy histology endometrial cancer resemble those of ovarian cancer.
Conclusions:
- Endometrial cancer with malignant histology or deep myometrial invasion may exhibit patterns of spread similar to ovarian cancer.
- Recommendations include radical hysterectomy with periaortic lymph node dissection, omentectomy, and peritoneal washing cytology for accurate staging and maximal curative potential.
