When There is No Cancer Cure, There Can be ‘Cancer Control’
Chief, Interventional Radiology, Northern Westchester Hospital
Some radical cancer therapies are being replaced in favor of treatments that honor a person’s wish for quality of life over prolongation of poor life.
One example is an interventional radiology treatment at Northern Westchester Hospital using trans arterial radioembolization, or TARE. TARE shows promise in prolonging quality of life for many patients battling liver cancer and metastatic colorectal cancer in the liver.
This unique interventional treatment delivers Yttrium-90, a radioactive isotope, directly to a tumor through the vascular system. It is a scientifically sophisticated technique for giving NWH patients a cancer treatment that doesn’t harm the healthy cells.
First, What is Interventional Radiology?
A subspecialty of Diagnostic Radiology, Interventional Radiology uses image guidance to perform minimally invasive procedures to treat a wide range of diseases.
Better Outcome for Our Patients
More than three-fourths of liver cancer patients can’t have surgery; TARE with Yttrium-90 gives patients more time. And as an interventional radiology procedure, it offers the benefits of a minimally invasive treatment:
- Reduced infection rates, risk, pain and recovery time
- Shorter hospital stays
- Uses under local anesthesia instead of general anesthesia
TARE with Yttrium-90 is an advanced treatment that is invaluable for patients with primary and secondary malignancies of the liver who have previously exhausted or who do not have other options in combating their liver cancer.
How TARE with Yttrium-90 Works
Tumors need a blood supply, which they actively generate, to feed themselves and grow. Interventional radiologists are uniquely skilled in using the vascular system to deliver targeted treatments via catheter throughout the body. In treating cancer patients, Interventional Radiologists can attack the tumor from inside the body without medicating or affecting other parts of the body.
Combining the radioactive isotope Yttrium-90 (also known as Y-90) into microspheres to deliver radiation directly to a tumor allows for a higher, local dose of radiation to be used-without subjecting healthy tissue in the body to the radiation.
Each microsphere is about the size of five red blood cells in width. These beads are injected through a catheter from the groin into the liver artery supplying the tumor. The beads become lodged within the tumor vessels where they exert their local radiation that kills the cancer cells. Y-90 radiates from within and is administered via the hepatic artery. Y-90 treatment is approved by the Food and Drug Administration for the treatment of inoperable liver cancer and metastatic colorectal cancer in the liver.
While this advanced treatment doesn’t cure liver cancer, the lives of patients at NWH are being extended and their quality of life is improved with Yttrium-90 microsphere treatment.
The Team Approach at NWH
Paramount to the application of this leading-edge treatment is the multidisciplinary collaboration at Northern Westchester Hospital between the Interventional Radiology Department and the Radiation Oncology Department, led by Dr. Alfred Tinger, Chief of Radiation Oncology in The Cancer Treatment and Wellness Center.
There are other interventional radiology treatments available at Northern Westchester Hospital that are used to treat primary liver cancer, as well as other cancers that have metastasized in the liver, such as colorectal cancer, breast cancer, gynecologic cancers, melanoma, and others. These nonsurgical interventional radiology treatments are:
- Trans arterial embolization (TAE)
- Trans arterial chemoembolization (TACE), which delivers chemotherapy directly to the liver
- Radiofrequency ablation (RFA), which kills the tumor with heat to treat the cancer locally.

NWH is one of only 5 Hospitals in New York State to offer Yttrium-90 therapy for the treatment of liver cancer. (The other hospitals are: Memorial Sloane-Kettering, NYU, Mt. Sinai and NY Presbyterian.)
