What is one application of interventional radiology in oncology?

• A. Blood transfusion
• B. Transarterial chemoembolization (TACE) for liver tumors
• C. Surgical resection of tumors
• D. Radiation therapy

Answer: (B)

Transarterial chemoembolization (TACE) is a specialized interventional radiology technique used primarily for treating liver tumors, especially when they are not amenable to surgical resection. TACE involves the selective delivery of chemotherapy directly into the blood supply of the tumor, combined with the embolization of blood vessels to restrict blood flow to the tumor. This dual approach effectively reduces the tumor size and limits its growth by directly targeting the cancer cells while simultaneously depriving them of essential nutrients and oxygen.

This method is particularly beneficial for patients with hepatocellular carcinoma (HCC) or metastatic liver cancer, as it can significantly improve outcomes when surgery isn't a viable option. The application of TACE illustrates the critical role interventional radiology plays in oncology, providing minimally invasive alternatives to more invasive surgical interventions and potentially enhancing quality of life for cancer patients. Other options, while relevant in broader medical contexts, do not represent the unique contributions of interventional radiology in oncology.
