Desmoid Tumors-Biology-Driven Management and Treatment Selection

Area of Science:

• Oncology
• Molecular Biology
• Neoplasms

Background:

• Desmoid tumors (DTs) are rare, locally aggressive fibroblastic neoplasms.
• Driven by Wnt signaling pathway alterations (CTNNB1 mutations or APC loss).
• Historically managed similarly to soft tissue sarcomas, often with aggressive surgery or chemotherapy.

Purpose of the Study:

• To review current management strategies for desmoid tumors.
• Highlight the shift towards active surveillance and molecularly targeted therapies.
• Discuss multidisciplinary approaches for optimizing patient outcomes.

Main Methods:

• Review of current literature on desmoid tumor biology and treatment.
• Analysis of historical and contemporary management paradigms.
• Evaluation of emerging therapeutic options.

Main Results:

• Active surveillance is suitable for many DTs due to potential for stability or regression.
• Molecularly targeted therapies (e.g., gamma secretase inhibitors) show promise.
• Novel local treatments like cryoablation and focused ultrasound are emerging.
• Surgery and traditional chemotherapy remain options for select cases.

Conclusions:

• Modern desmoid tumor management emphasizes individualized, multidisciplinary care.
• Active surveillance is a key initial strategy.
• Targeted therapies and novel local treatments offer new hope for aggressive or symptomatic DTs.
• Optimizing treatment minimizes morbidity and improves quality of life.
