Additional options for patients with difficult to
reach cancers or for patients who are not surgical
candidates utilize interventional radiologists who
specialize in less-invasive procedures including:
Chemoembolization
In chemoembolization, microscopic glass beads
coated in chemotherapy are injected into the
blood vessel that supplies the cancer. This delivers
a local dose of chemotherapy to the tumor
without the side effects associated with traditional
chemotherapy. The beads keep the chemotherapy
trapped in the cancer instead of circulating in the
blood system, and this starves the tumor of its blood
supply. Side effects may include nausea, pain and
fatigue. Patients generally go home the same day or
the next morning after receiving chemoembolization treatment.
Y90/yttrium-90/directed radiation bead therapy
Patients with large tumors, multiple tumors in the
same region of the liver, and/or tumor within the
portal vein (a large vein of the liver) can potentially
receive radiation bead therapy. These beads are
coated with radiation instead of chemotherapy.
This procedure is used after a detailed mapping
that determines how much radiation will go through
the liver and on to other areas of the body. If the
amount of radiation going to the lungs or other
areas is too much, radiation bead therapy is not safe
to use. If the mapping determines a safe path for the
radiation, radiation beads are injected into the blood
vessel of the tumor. These radiation coated beads
implant into the tumor and work to destroy the
cancer cells.
