Unresectable Primary Tracheal Synovial Sarcoma.

Area of Science:

• Oncology
• Rare Cancers
• Head and Neck Neoplasms

Background:

• Synovial sarcoma (SS) is a rare malignancy, accounting for less than 1% of head and neck cancers.
• Primary tracheal SS in adults is exceptionally rare, with fewer than five cases previously reported.
• Understanding the clinical course of such rare tumors is crucial for effective management.

Purpose of the Study:

• To report the first case of adult primary tracheal synovial sarcoma treated with curative-intent radiation and pazopanib.
• To contribute to the limited understanding of the presentation, diagnosis, and natural history of primary tracheal SS.
• To document treatment outcomes for this rare oncological entity.

Main Methods:

• Retrospective chart review of a single patient case.
• Data collection on patient demographics, clinical presentation, diagnostic findings, and treatment course.
• Analysis of treatment response and disease progression.

Main Results:

• A woman in her forties presented with shortness of breath due to an unresectable primary tracheal SS.
• Initial treatment with curative-intent radiation therapy was administered.
• Subsequent metastatic disease was managed with systemic chemotherapy using pazopanib.

Conclusions:

• This case represents the first reported instance of adult primary tracheal SS.
• The findings enhance the understanding of primary tracheal SS presentation, diagnosis, and natural history.
• This case provides valuable insights into treatment strategies and outcomes for this rare tumor.
