Our highly trained specialists are available 24/7 via phone and on weekdays can assist through online chat. We connect patients, caregivers, and family members with essential services and resources at every step of their cancer journey. Ask us how you can get involved and support the fight against cancer. Some of the topics we can assist with include:
For medical questions, we encourage you to review our information with your doctor.
Surgery, either with surgical resection (removal of the tumor) or a liver transplant, offers the best option to cure liver cancer, if it can be done. Surgery may not be possible if the tumor is large and takes up too much of the liver, the liver is too damaged, the cancer has spread outside of the liver, or if you have other serious illnesses.
Partial hepatectomy is surgery to remove part of the liver. To have this surgery, people generally need to have a good liver function, good overall health, and have a single tumor that has not grown into blood vessels.
Imaging tests such as CT or MRI are done first to see if the cancer is resectable – that is, if it can be removed completely. Still, sometimes during surgery the cancer is found to be too large or has spread too far to be removed, and the surgery that was planned cannot be done.
For some people who have unresectable liver cancer, using other treatments first might shrink the tumor enough so that surgery could then be an option.
In the United States, most people with liver cancer also have cirrhosis. For someone with severe cirrhosis, removing even a small amount of normal liver tissue at the edges of a cancer might not leave enough healthy liver behind to perform important functions.
People with cirrhosis might still be eligible for surgery if there is only one tumor (that has not grown into blood vessels) and they will still have a reasonable amount of liver function left once the tumor is removed. Doctors often assess this function by assigning a Child-Pugh score (see Liver Cancer Stages), which is a measure of cirrhosis based on certain lab tests and symptoms.
People in Child-Pugh class A are most likely to have enough liver function to have surgery. People in class B are less likely to be able to have surgery. Surgery is not typically an option for people in class C.
After surgery, the remaining section of liver takes over the functions of the entire liver. A healthy liver may grow back to its normal size over time.
Liver resection is a major, serious operation that should only be done by skilled and experienced surgeons. People with liver cancer usually have other liver problems besides the cancer. In this case, surgeons have to remove enough of the liver to get all of the cancer, but also leave enough behind for the liver to function.
When it is available, a liver transplant may be the best option for some people with liver cancer.
Liver transplants can be an option for those with tumors that cannot be removed with surgery, either because of the location of the tumor(s) or because the liver has too much disease for the person to tolerate removing it all.
In general, a transplant might be an option to treat people with small tumors that have not grown into nearby blood vessels.
Rarely, a transplant can also be an option for people with cancers that can be removed completely. Possible advantages of a transplant in this setting are that the risk of getting a new liver cancer is much lower, and the new liver will function normally. But this has to be weighed against the complexity and possible long-term side effects of a liver transplant.
Unfortunately, there are only a limited number of donor livers available for transplant each year, and most of these are used for people with diseases other than liver cancer. Increasing awareness about the importance of organ donation is an essential public health goal that could make this treatment available to more people with liver cancer and other serious liver diseases.
Most livers used for transplants come from people who have just died. But some people can get part of a liver from a living donor (usually a close relative) for a transplant. The liver can regenerate some of its lost function over time if part of it is removed. Still, the surgery does carry some risks for the donor.
People needing a transplant must wait until a liver becomes available, which often can take too long for some people with liver cancer. In many cases a person may get other treatments, such as embolization or ablation, while waiting for a liver transplant. Or doctors may suggest surgery or other treatments first and then a transplant if the cancer comes back.
Like partial hepatectomy, a liver transplant is a major operation with serious risks and should only be done by skilled and experienced surgeons. Possible risks include:
