If you or a loved one have recently been diagnosed with colorectal cancer that has metastasized to the liver, it is important to understand the options for treatment.
The hard truth is that nearly 140,000 Americans are diagnosed with colorectal cancer every year. More than half of these patients will see their cancer spread to the liver and many will die of this disease. 1, 2
Clinical studies have confirmed that patients with metastatic colorectal cancer treated with SIR-Spheres® Y-90 resin microspheres have a response rate higher than with other forms of treatment, resulting in increased life expectancy, greater periods without tumor activity and improved quality of life. SIR-Spheres also known as Selective Internal Radiation Therapy (SIRT) has been found to shrink liver tumors more than chemotherapy alone. 3-5
SIR-Spheres Y-90 resin microspheres are administered through a small catheter and inserted into the femoral artery.
SIR-Spheres Y-90 resin microspheres are an FDA approved medical device intended for the treatment of colorectal cancer that has spread to the liver and cannot be surgically removed. These microscopic polymer beads travel easily through the bloodstream directly to the liver where they become lodged in the tumor and kill the cancer cells.
This form of therapy delivers a dose of internal radiation up to 40 times higher than conventional external therapy, while sparing healthy tissues.6
The SIR-Spheres Y-90 resin microspheres procedure typically lasts 60 to 90 minutes and is performed as an outpatient procedure by an interventional radiologist. This minimizes the time spent at the hospital and allows for more time living a normal life. Patients will be sleepy during the procedure but able to communicate with the doctor.
While the SIR-Spheres treatment is well-tolerated by patients and typically has little to no side effects, every patient reacts differently to treatments and some patients may experience unwanted side effects. Side effects of SIRT are generally mild, including tiredness, loss of appetite, mild fever, stomach pain, sickness, injection site soreness and diarrhea. There is no hair loss with this treatment. If symptoms do arise they normally subside within a week and medications can be prescribed to control these symptoms.
SIR-Spheres therapy is an option for patients who have shown a limited response or are no longer responding to other treatments. This therapy is a way for people with cancer to live a comfortable life and spend time with loved ones while maintaining a good quality of life. 5
It is normal to be scared and confused when it comes to treatment options. It is important to be informed and talk to your physician if you have any questions or concerns.
