Radioembolization of liver tumors
Radio Chemoembolization
Radioembolization of the hepatic artery is an innovative method that combines chemotherapy and radiotherapy simultaneously. This approach not only facilitates chemotherapy for liver tumors but also administers radiotherapy to the tumors. The concurrent application of these two methods provides a more effective therapeutic outcome for the patient.
Radiopharmaceutical
Radiopharmaceuticals are radioactive particles capable of emitting beta radiation, which can irradiate an area within an 80 to 100-millimeter radius around them, effectively destroying tumor cells through radiation. By injecting the radiopharmaceutical directly into the liver, liver tumors can be targeted for localized radiotherapy, allowing for precise radiation treatment at close range.
Advantages of Radioembolization
Simultaneous administration of chemotherapy and radiotherapy for liver lesions
A more favorable therapeutic outcome is achieved through the combined application of chemotherapy and radiotherapy.
The persistence of radiopharmaceutical properties in the liver for a duration of two weeks.
Accelerating the treatment of metastases, leading to a reduction in tumor size.
Necessary Preparations for Radioembolization Procedure
Fasting for approximately 6 hours prior to the procedure.
Removing unwanted hair from the groin area
Carrying medical documents related to the illness.
Perform a blood coagulation test prior to surgery.

Necessary Preoperative Examinations
It is necessary for your liver function to be evaluated by a specialist at the center. If you have a history of heart disease or diabetes, be sure to inform your doctor so that appropriate measures can be taken. Additionally, if you are taking medications such as warfarin, aspirin, or Plavix, make sure to notify your physician.
Method of Performing Radio Chemoembolization Procedure
This procedure is performed under the guidance of imaging equipment and with local anesthesia. Initially, a specialized catheter is inserted into the hepatic artery through the right femoral artery. After performing angiography of the hepatic artery and identifying the tumor’s feeding vessels, the catheter is directed into the tumor’s blood-supplying vessels. Subsequently, chemotherapy drugs and radiopharmaceuticals, along with embolizing agents, are injected into the tumor’s blood-supplying vessels.
Postoperative Symptoms
Feeling pain after undergoing this procedure is common and will typically respond to painkillers, depending on the location and extent of the lesion, and will subside over time.
Mild fever may persist for up to a week after the injection. Medications will also be administered during and after the procedure to manage nausea and vomiting, which is completely normal (due to the simultaneous use of chemotherapy drugs and radiopharmaceuticals). It should be noted that the presence of these symptoms following the radiochemoembolization procedure is expected. However, in the event of sudden changes, high fever, chills, or uncontrollable pain, be sure to inform your treating physician immediately.
This procedure is typically performed on an outpatient basis, and the patient is discharged 3 to 4 hours afterward. However, depending on the patient’s condition, hospitalization for up to 24 hours after the procedure may be necessary.
Post-Procedure Follow-Up Measures After Radioembolization
The patient will be able to resume normal activities after one week. To evaluate the success of the treatment, a CT scan or MRI will be performed at the center one month after the radio-chemoembolization procedure. Subsequent sessions of radio-chemoembolization will be scheduled based on the response to the treatment.
Attention:
The injected radioactive substance emits low-range beta radiation, posing no risk to those around the patient. It is not excreted through urine or feces. Therefore, no special precautions are necessary, and the radioactive material will naturally decay over time.
Upon discharge, you will also be provided with pain relievers, antipyretics, anti-nausea medications, and antibiotics.
Frequently Asked Questions
What is radioembolization and how does it work?
In this method, the chemotherapy drug, along with embolizing agents, is directly injected into the lesion through the artery supplying the tumor. This simultaneously blocks the tumor’s blood supply and delivers a localized effect of the anticancer drug.
Who is this method suitable for?
Radioembolization is typically used for patients with inoperable liver tumors or those who are not suitable candidates for surgery. It can be effective in controlling tumor growth.
Is hospitalization required after undergoing this procedure?
This procedure is typically performed with a short hospital stay, and depending on the patient’s condition, discharge usually occurs within 1 to 2 days.
