Local Ablative Therapies to Metastatic Soft Tissue Sarcoma

Area of Science:

• Oncology
• Interventional Radiology
• Surgical Oncology

Background:

• Metastatic soft tissue sarcoma (STS) treatment is complex, influenced by disease extent, histology, and patient factors.
• Systemic chemotherapy for metastatic STS has suboptimal efficacy, necessitating exploration of local therapies.
• Historically, surgery was primary for isolated metastases; radiation focused on palliation.

Purpose of the Study:

• To review current and emerging local ablative and catheter-directed therapies for metastatic STS.
• To discuss the integration of surgery, radiation, and interventional radiology in a multidisciplinary approach.
• To emphasize the importance of personalized treatment strategies for metastatic STS.

Main Methods:

• Review of surgical approaches for lung and liver metastases.
• Discussion of radiation therapy advancements and current applications.
• Overview of interventional radiology techniques including radiofrequency ablation, cryoablation, and hepatic artery embolization.

Main Results:

• Surgery is a primary option for isolated metastases, though evidence for liver metastases is limited.
• Interventional radiology offers durable tumor eradication (radiofrequency ablation, cryoablation) and management of unresectable liver metastases (hepatic artery embolization).
• Radiation therapy's role may expand with advanced techniques, beyond palliation.

Conclusions:

• A multidisciplinary approach integrating surgery, radiation, and interventional radiology is crucial for metastatic STS.
• Personalizing treatment based on individual patient and disease characteristics is key.
• Understanding the optimal timing and role of each modality can improve patient outcomes.
