Lu-177 and Y-90 are becoming the main RNT agents. Iodine-131, samarium-153, and phosphorus-32 are also used for therapy.
Does radioactive treatment for liver cancer extend life?
Compared with the standard treatment, this new method also appears to be safer—but it doesn’t offer a longer life. An experimental liver cancer treatment of radioactive beads did not lead to a greater survival benefit compared with the standard treatment, but it was superior in measures of safety and quality of life, MedPage Today reports.
Can radioactive beads help liver cancer patients?
Treating Liver Cancer With Radioactive Beads Improves Quality of Life. The researchers randomly assigned the participants to receive 800 mg of sorafenib daily or SIRT, in which tiny radioactive beads were injected into carefully chosen liver arteries that would deliver the beads into or near the tumors.

What kind of radiation is used to treat liver cancer?
Newer radiation techniques, such as stereotactic body radiation therapy (SBRT), help doctors target liver tumors while reducing the radiation to nearby healthy tissues. This makes it more effective and reduces side effects. SBRT allows treatment to be completed in a short-time compared to EBRT.

What is targeted radiation to the liver called?
Also called radioembolisation, SIRT is a treatment that precisely targets cancers in the liver with high doses of radiation while causing little damage to normal liver tissue. It uses tiny radioactive beads known by the brand name SIR-Spheres.
What is radioisotope therapy?
Radioisotope therapy is a procedure in which a liquid form of radiation is administered internally through infusion or injection. RIT's ultimate purpose is to treat cancerous cells with minimal damage to the normal surrounding tissue. These therapies are not normally the first approach used to fight a patient's cancer.

The most common side effect from radioisotope therapy is a feeling of tiredness for a few weeks. Radioisotope therapy can treat a wide variety of cancers, including bone metastases, brain cancer, thyroid cancer, bile duct cancer, liver cancer, and neuroblastoma.
How long does radiation last after a radiotherapy injection?
These injections or infusions can often be followed by a short period of radiation application, normally around one week. While the amount of radiation in a patient's body following radioisotope therapy will be higher than normal, those levels will recede with time, usually no more than a few days.
Can radioisotopes be used after other therapies?
Instead, they are more likely to be used after other therapies . Initial radioisotope therapy is relatively brief, as many forms of the therapy are administered via a series of injections or single infusions.
Is radioisotope therapy a cancer treatment?
Radioisotope therapy can also be useful as an adjuvant, or assisting, therapy when combined with other forms of cancer therapy.
Why are liver tumors inoperable?
Liver tumors are often inoperable because the tumors may be too large or numerous or have grown into major blood vessels or other vital structures. Historically, chemotherapy drugs become less effective as the disease progresses," he added.
Why did the Nuclear Regulatory Commission change its guidelines?
The Nuclear Regulatory Commission recently changed its guidelines in order to create a specific pathway for interventional radiologists to become authorized users. Last month in Arizona, 106 participants attended the SIR's Y-90 course, developed to ensure that SIR members not only meet but exceed these requirements.
Is Y-90 safe for liver cancer?
