Embolization is an option for some patients with tumors that cannot be removed by surgery. It can be used for tumors that are too large to be destroyed with ablation – usually larger than 4 cm.
Embolization has been used by our experienced Interventional Radiologists since 2004 to treat inoperable liver tumors, typically from primary liver cancer as well as metastases from colorectal cancer, breast cancer, gynecologic cancer, melanoma and other cancers that spread to the liver. It was first used in Westchester by Dr. Carlos Forcade. Every member of our Interventional Radiology team at NWH is specially trained in embolization procedures.

Radiofrequency Ablation is a minimally invasive treatment for cancer. Imaging technology such as Ultrasound and Computed Tomography (CT Scan) are used to guide a needle electrode into a tumor. High-frequency electrical currents are passed through the electrode, creating heat that destroys or ablates the abnormal cells.
In Trans arterial embolization a catheter (a thin, flexible tube) is put into the common femoral artery through a small cut in the inner thigh and threaded into the hepatic artery in the liver, guided with IV contrast and Fluoroscopy. Once the catheter is in place, small particles are injected into the hepatic artery to induce ischemia, or restriction of blood supply to the tumor.
Trans arterial chemoembolization combines chemotherapy with embolization. Chemoembolization attacks the cancer in two ways: First, it delivers a very high concentration of chemotherapy, or anti-cancer drugs, directly into the tumor, without exposing the entire body to the effects of those drugs. Second, the procedure cuts off blood supply to the tumor, trapping the anti-cancer drugs at the site and depriving the tumor of the oxygen and nutrients it needs to grow. X-Ray images are taken to map the path of the blood vessels feeding the tumor and to pinpoint the site for the procedure.
Chemoembolization can help prevent the growth of the tumor and can be used in combination with other types of therapy, such as Tumor Ablation,Chemotherapy, or Radiation, to treat cancer metastases while potentially preserving liver function.
Trans arterial radioembolization uses embolization to deliver millions of tiny radioactive beads called SIR-Spheres® into the hepatic artery–precisely where liver tumors receive most of their blood supply. Once infused, the beads lodge in the blood vessels near the tumor, where they give off small amounts of yttrium-90 (Y-90) radiation to the tumor site for several days. The radiation travels a very short distance, so its effects are limited mainly to the tumor.
TARE has been used by the experienced Radiation Oncologists and Interventional Radiologists at NWH since 2010 to treat inoperable liver tumors, typically from primary liver cancer and colorectal metastasis that has spread to the liver.
Our Team Approach Paramount to the application of this advanced treatment at NWH is the multidisciplinary collaboration between Dr. Carlos Forcade, Director of Interventional Radiology, and Dr. Alfred Tinger, Chief of Radiation Oncologyin The Cancer Treatment and Wellness Center.
