Malignant gestational trophoblastic disease: CT findings
AJR. American Journal of Roentgenology
|January 1, 1987
Summary
Computed tomography (CT) of the pelvis in patients with malignant gestational trophoblastic disease revealed distinct uterine appearances. These CT findings correlate with distant metastases and the need for hysterectomy, aiding in treatment decisions.
Area of Science:
- Radiology
- Oncology
- Gynecology
Background:
- Malignant gestational trophoblastic disease (GTD) requires accurate staging for effective treatment.
- Pelvic CT is utilized for staging GTD prior to chemotherapy.
Purpose of the Study:
- To analyze the CT appearance of the uterus in patients with malignant GTD.
- To correlate CT findings with prognostic factors and treatment outcomes.
Main Methods:
- CT scans of the pelvis were performed on eight patients with malignant GTD before chemotherapy.
- Uterine CT appearances were categorized into three types.
- Correlation with surgical specimens was performed where available.
Main Results:
- Three distinct CT patterns of uterine involvement were identified.
- Patients with uniform or focal uterine enlargement on CT had higher rates of distant metastases and hysterectomy.
- CT accurately depicted myometrial and parametrial tumor nodules in correlation with surgical findings.
Conclusions:
- CT imaging of the uterus in malignant GTD has prognostic value.
- CT findings can predict the likelihood of distant metastases and the need for hysterectomy.
- CT is valuable for assessing the extent of GTD, guiding therapeutic strategies.
