Types of Interventional Radiology Oncology Procedures

Interventional radiology oncology encompasses a variety of procedures, each designed to target cancer in a unique way. These techniques can be broadly categorized into ablation, embolization, and brachytherapy, each offering distinct advantages depending on the type and location of the tumor.

Ablation techniques involve using heat or cold to destroy cancer cells. Radiofrequency ablation (RFA) uses high-frequency electrical currents to heat and destroy tumors. Microwave ablation (MWA) uses microwaves to generate heat and ablate cancerous tissue. Cryoablation uses extreme cold to freeze and destroy tumors. These techniques are commonly used to treat liver, kidney, and lung tumors. Embolization techniques involve blocking the blood supply to the tumor, depriving it of oxygen and nutrients. Transarterial chemoembolization (TACE) delivers chemotherapy drugs directly to the tumor while blocking its blood supply. Transarterial radioembolization (TARE), also known as Y-90 radioembolization, uses radioactive microspheres to deliver radiation directly to the tumor. These techniques are commonly used to treat liver cancer. Brachytherapy involves placing radioactive seeds directly into or near the tumor. This allows for a high dose of radiation to be delivered to the tumor while minimizing exposure to surrounding healthy tissue. Brachytherapy is commonly used to treat prostate cancer, breast cancer, and cervical cancer. Each of these procedures offers unique benefits and is tailored to the specific needs of the patient.

The choice of procedure depends on several factors, including the type and size of the tumor, its location, and the overall health of the patient. Interventional radiologists work closely with oncologists and other specialists to determine the most appropriate treatment plan for each individual. Image guidance, such as CT scans, MRI, and ultrasound, is used to precisely guide the instruments and deliver the treatment to the targeted area. This ensures that the tumor is effectively treated while minimizing damage to surrounding healthy tissue. In addition to these primary techniques, interventional radiology oncology also includes procedures such as venous access for chemotherapy, paracentesis and thoracentesis for fluid drainage, and pain management interventions. These procedures play an important role in managing the symptoms and improving the quality of life for cancer patients.
