Desmoid tumors: need for an individualized approach

Area of Science:

• Oncology
• Surgical Pathology
• Radiation Oncology

Background:

• Desmoid tumors (aggressive fibromatosis) are rare, locally invasive fibroblastic proliferations.
• Despite being histologically benign, they have high local recurrence rates and heterogeneous behavior.
• Optimal treatment strategies remain controversial, necessitating individualized patient care.

Purpose of the Study:

• To review current treatment modalities for desmoid tumors.
• To discuss the role of surgery, radiotherapy, and systemic therapies.
• To highlight factors influencing treatment decisions and outcomes.

Main Methods:

• Review of existing literature on desmoid tumor management.
• Analysis of treatment outcomes based on surgical margins, radiotherapy, and systemic agents.
• Identification of risk factors for local tumor control failure.

Main Results:

• Wide surgical excision is often the primary treatment, but morbidity must be considered.
• Postoperative radiotherapy reduces recurrence, especially with involved margins.
• Radiotherapy for gross disease is effective but carries dose-dependent complications.
• Systemic therapies and watchful waiting are emerging options for specific cases.

Conclusions:

• Individualized treatment is crucial for desmoid tumors, balancing efficacy and quality of life.
• Surgery and radiotherapy play key roles, with specific indications and limitations.
• Watchful waiting and systemic therapies offer alternatives when standard treatments are too morbid or contraindicated.
