Dermatofibrosarcoma Protuberans, Version 1.2025, NCCN Clinical Practice Guidelines In Oncology

Area of Science:

• Oncology
• Dermatology
• Surgical Pathology

Background:

• Dermatofibrosarcoma protuberans (DFSP) is a rare malignant neoplasm of the skin.
• DFSP is characterized by extensive local infiltration and a high rate of recurrence.
• Metastasis is uncommon, but the fibrosarcomatous variant presents an increased risk.

Purpose of the Study:

• To summarize the key aspects of Dermatofibrosarcoma protuberans (DFSP).
• To highlight the importance of surgical margins in DFSP treatment.
• To outline alternative treatment modalities for unresectable or recurrent DFSP.

Main Methods:

• Review of existing literature on Dermatofibrosarcoma protuberans.
• Analysis of treatment strategies including surgical excision, radiation therapy, and systemic treatments.
• Reference to the NCCN Clinical Practice Guidelines for Oncology.

Main Results:

• Surgical excision with negative margins is the primary treatment for DFSP.
• Achieving negative margins is crucial for minimizing local recurrence.
• Radiation therapy and systemic treatments are viable options when complete resection is not feasible.

Conclusions:

• Dermatofibrosarcoma protuberans requires careful surgical management to prevent recurrence.
• Aggressive variants like fibrosarcomatous DFSP necessitate prompt and potentially multimodal treatment.
• Adherence to established guidelines, such as the NCCN Guidelines, ensures optimal patient care.
