Tenosynovial Giant Cell Tumor and Pigmented Villonodular Synovitis

Area of Science:

• Orthopaedic Surgery
• Oncology
• Pathology

Background:

• Tenosynovial giant cell tumors (TGCTs) are a spectrum of benign growths.
• They can present in intra-articular or extra-articular locations with varying patterns of synovial infiltration.
• Surgical resection is the primary treatment, but high recurrence rates persist.

Purpose of the Study:

• To review the etiology, clinical presentation, diagnosis, and treatment of TGCTs.
• To highlight advancements in understanding TGCT pathogenesis.
• To discuss modern treatment options beyond traditional surgery.

Main Methods:

• Literature review of TGCTs.
• Analysis of genetic and environmental factors.
• Examination of novel therapeutic targets and adjuvant medications.

Main Results:

• TGCTs can be locally aggressive with significant recurrence rates post-surgery.
• Tumor cell expression of colony-stimulating-factor-1 drives proliferation and inflammation.
• Adjuvant medications targeting these pathways show promise in improving outcomes.

Conclusions:

• A comprehensive understanding of TGCTs is essential for effective management.
• Multidisciplinary collaboration is key for optimizing patient care.
• Targeted therapies represent a significant advancement in managing recurrent or aggressive TGCTs.
