Desmoid tumours (extra-abdominal), a surgeon's nightmare

Area of Science:

• Oncology
• Surgical Pathology

Background:

• Desmoid tumors are rare fibroblastic neoplasms of monoclonal origin.
• They exhibit locally aggressive behavior without metastatic potential, presenting a heterogeneous clinical course.
• Commonly arising in deep soft tissues, particularly the limbs, they can cause significant disability and pain.

Purpose of the Study:

• To review the complex management of desmoid tumors.
• To discuss the shift from primary surgical resection to conservative strategies.
• To highlight emerging treatments and areas of ongoing controversy.

Main Methods:

• Literature review of desmoid tumor management.
• Analysis of historical and current treatment trends.
• Discussion of surgical and non-surgical therapeutic options.

Main Results:

• Surgical resection, once the primary approach, is increasingly supplemented by a 'wait and see' policy.
• Various medical and regional treatments are available, with new promising options emerging.
• Significant challenges remain due to the tumor's unpredictable behavior and limited evidence.

Conclusions:

• Desmoid tumor management requires a nuanced approach due to their complex nature.
• Further research and global collaboration are essential for developing standardized, evidence-based treatment guidelines.
• Prospective, randomized data are needed to establish a shared, stepwise management strategy.
