liver cancer

Liver cancer may start out as a small lump, called a tumour, and can grow larger or develop in more than one site in the liver over time. It starts slowly in a liver that has been exposed to certain risk factors for liver cancer.

what is liver cancer?

Liver cancer begins with the formation of a malignant tumour and can, over time, grow larger and spread from more than one site in the liver. The most common form of primary liver cancer is hepatocellular carcinoma (cancer of the liver cells). Another type of primary liver cancer is called cholangiocarcinoma, which originates in small bile ducts (bile ducts carry bile from the liver to gallbladder).

In many cases, when cancer occurs in the liver, it was spread from a cancer that began at another site (known as secondary liver cancers or cancer metastasis). Cancer cells can spread, settle, and grow in the liver due to the liver filtering blood from around the body. When liver cells are injured, they can be regenerated, and this process can lead to mutations that are linked to cancer development.

who is at risk?

fast facts

  • It is projected that in 2024, there will be an estimated 4700 new cases of liver and intrahepatic bile duct cancer in Canada.
  • Around 75% of primary liver cancer is hepatocellular carcinoma.
  • Liver cancer is the 4th leading cause of cancer death worldwide.

symptoms

  • pain in upper right side of abdomen or in the back and shoulder
  • fluid buildup in abdomen (ascites)
  • fatigue and weakness
  • mental confusion or disorientation
  • itchiness
  • edema,
  • loss of appetite
  • nausea
  • dark urine
  • jaundice

what can I do?

diagnosis

Liver cancer can be diagnosed through a blood test, ultrasound, computer tomography scan (CT), magnetic resonance imaging (MRI), or liver biopsy.

prevention

  • Vaccinate against Hepatitis B
  • Test for Hepatitis C if you are at risk and for all adults born between 1945 and 1975
  • Consume a healthy, balanced diet and introduce physical activity to your daily routine to prevent MAFLD
  • Individuals at risk of liver cancer should be monitored regularly by their doctor to increase chance of early detection

management

Symptom management is an important aspect of coping with liver cancer. When symptoms are addressed and managed, it can significantly strengthen the capability and overall quality of life.

treatment

Different treatment options of hepatocellular carcinoma depends on the stage of the cancer (size and growth of tumours):

  • Surgery (partial hepatectomy) is used for individuals with good liver function or for those with small tumours. However, if the cancer is large or found in many different parts of the liver, or in many people with cirrhosis, there is not enough healthy liver left to allow for removal of a portion of the liver.
  • Tumour ablation refers to various methods used to destroy the tumour without removing it and includes radiofrequency ablation, microwave therapy, and cryoablation.
  • Embolization refers to blocking or reducing blood flow in the hepatic artery (feeds the liver with blood), which stops tumour growth. Chemoembolization combines embolization with anti-cancer drugs (chemotherapy) while radioembolization delivers beads with radiation.
  • Radiation therapy and chemotherapy are other methods used to kill cancer cells.
  • Targeted drug therapy are medications that target specific abnormalities within the cancer cells (e.g their genes, protein, tissue) without harming normal cells. They are considered first line therapy and their use is limited to those who remain active and well, and do not have liver failure.
  • Immunotherapies act on specific parts of the immune system to better fight cancer cells and is often used if other treatments are ineffective.

Most cancers of the liver begin elsewhere in the body and are spread to the liver. These cancers are not curable through liver transplantation. Tumours that start in the liver are usually detected in an advanced stage. They are also rarely cured by a liver transplant. If the primary liver cancer is small and confined to the liver, a liver transplant may be considered.

  • What stage of liver cancer do I have?
  • How wide spread is my stage of liver cancer?
  • Can I receive a liver transplant?
  • What lifestyle modifications should I make?
  • What treatments/medications are available?
