Mediastinal Metastasis Isolated in Ovarian Cancer: A Systematic Review.

Area of Science:

• Oncology
• Gynecologic Oncology

Background:

• Isolated mediastinal metastases from ovarian carcinoma are exceptionally rare.
• These metastases typically indicate advanced disease, with systemic therapy as the standard approach.
• Surgical excision has been reported as a feasible management option in select cases.

Purpose of the Study:

• To review and present cases of isolated mediastinal metastases from ovarian cancer.
• To analyze the management strategies and outcomes for these rare occurrences.
• To highlight the potential role of surgical intervention.

Main Methods:

• A comprehensive review of the English-language literature was conducted.
• Cases of isolated mediastinal ovarian cancer metastases were identified.
• Management approaches and patient outcomes were documented and analyzed.

Main Results:

• Fifteen cases were reported between 1998 and 2022, including 4 primary presentations and 11 recurrences.
• All reported tumors exhibited serous histology.
• Management varied, with 11 patients undergoing surgical resection, 2 receiving systemic therapy, and others treated with combined modalities.

Conclusions:

• Solitary mediastinal metastasis from ovarian cancer is a rare clinical finding.
• Physicians should maintain vigilance for these metastases during thoracic imaging evaluation of ovarian cancer patients.
• Individualized management, including surgical resection, should be considered, though definitive conclusions await larger studies.
