MICROWAVE ABLATION FOR non-resectable LIVER TUMOURS
Microwave ablation is a minimally invasive procedure in which the doctor uses targeted heat to destroy a non-resectable tumour. Ablation can be performed in an outpatient setting and may be used alone or in combination with chemotherapy, radiation, or other therapies.1 Studies show that ablation is a good alternative when a liver tumor cannot be removed surgically.2-4
Microwave ablation procedures are not recommended for patients with cardiac pacemaker or other implanted electronic devices. Potential risks have not been evaluated.
Microwave ablation procedures are not recommended for pregnant patients. Potential risks to the patient and/or fetus have not been established.
OTHER INTERVENTIONS FOR LIVER TUMOURS
SURGICAL REMOVAL
In a procedure called a partial hepatectomy, the surgeon removes the part of the liver containing the tumour. However, surgical removal is only feasible in approximately 10–20% of cases.5
TRANSPLANT
Your doctor may consider a liver transplant if the tumour(s) cannot be removed with surgery.
RADIATION
Targeted doses of radiation can destroy or shrink liver tumuors.
CHEMOTHERAPY
Chemotherapy involves delivering drugs throughout the body to destroy as much of the tumour(s) as possible.
EMBOLISATION
This minimally invasive technique destroys the tumour by placing substances inside the tumour to cut off blood supply to the tumour cells. The substances may include chemotherapy drugs or radiation therapy agents.
WATCHFUL WAITING
Your doctor may choose to monitor the tumour carefully over time to see if it is growing or causing liver damage.
THE RIGHT
OPTION FOR YOU
DEPENDS ON
MANY FACTORS
Your doctor will consider many factors in determining the right intervention for your liver tumour(s), including:
- Number, size, and location of tumour(s) in your liver
- Health and functioning of your liver
- Your overall health
- Whether you have primary or secondary (metastatic) liver tumour(s)
- Whether your tumours have spread outside the liver
