What Is Liver Cancer?
Liver cancer, also known as hepatocellular carcinoma (HCC), is a severe condition that develops when abnormal cells in the liver grow uncontrollably and compromise the immune system. These tumors can disrupt normal liver function and can be life-threatening if left untreated.
The liver is a vital organ responsible for various functions, including:
-
Filtering toxins from the blood;
-
Producing proteins;
-
Storing nutrients.
Liver cancer has two main types based on a malignancy location:
-
🔺Primary liver cancer derives from liver cells;
-
🔻Secondary liver cancer is a metastasis of a tumor from a different location.
Primary liver cancer accounts for about 2% of all cancers in the U.S. and affects twice as many men as women, with an average age of diagnosis at 67. It has two main subtypes:
-
🔬 Hepatocellular carcinoma (HCC) is the most common type, accounting for about 90% of all liver cancers. It originates in the primary type of liver cells called hepatocytes.
-
🔬 Intrahepatic cholangiocarcinoma (ICC) is a less common type that starts in the bile ducts responsible for transporting bile, a digestive fluid. The doctors call this type "bile duct cancer".
Liver cancer can affect people of all ages, but it's more common in individuals with certain risk factors.
What Are the Risk Factors for Liver Cancer?
The main risk factors of primary liver cancer include having hepatitis B or hepatitis C. These diseases are destroying liver cells, increasing their chances for mutation. Several other factors can increase a person's risk of developing liver cancer.
These include:
Cirrhosis
Cirrhosis, the scarring of liver tissue due to long-term damage, significantly increases the risk of liver cancer. When the liver attempts to repair itself repeatedly, scar tissue formation impairs its function and elevates the likelihood of emerging tumor cells.
Patients with cirrhosis, regardless of the underlying cause, are typically under surveillance for liver cancer, as they are at a higher risk of developing HCC.
Lifestyle Factors
Liver cancer specialists claim that heavy alcohol consumption over time can cause liver inflammation and damage, leading to cirrhosis and an increased likelihood of cancer development.
Obesity is another critical risk factor, as it is associated with nonalcoholic fatty liver disease (NAFLD), which can progress to cirrhosis and liver cancer. Additionally, smoking has been linked to a higher risk of liver cancer, as the harmful chemicals in tobacco can contribute to liver damage over time.
Genetic Factors
Hemochromatosis, a disorder where the body absorbs too much iron, can lead to iron buildup in the liver, causing cirrhosis and increasing cancer risk. Another genetic disorder, alpha-1 antitrypsin deficiency, can result in liver disease, particularly in children and young adults, by causing abnormal protein accumulation in the liver cells, leading to cirrhosis.
Exposure to Toxins
Chronic exposure to certain toxins significantly heightens the risk of liver cancer. Aflatoxins, produced by a specific mold that grows on improperly stored grains and nuts, are a well-known carcinogen, particularly in developing countries with poor food safety practices.
Plus, industrial chemicals like vinyl chloride, used in plastics manufacturing, have been linked to liver tumors. Individuals working in industries with chemical exposure or those living in areas with poor food safety measures are at a heightened risk for developing liver tumors.
What Are the Symptoms of Primary Liver Cancer?
Early-stage tumor often presents with no noticeable symptoms. However, as the cancer progresses, some potential signs and symptoms include:
-
Unexplained weight loss;
-
Loss of appetite;
-
Fatigue;
-
Nausea and vomiting;
-
Abdominal pain or swelling in the upper right abdomen;
-
Jaundice (yellowing of the skin and eyes);
-
Enlarged liver (hepatomegaly);
-
Dark-colored urine.
*Please note that the symptoms mentioned above could indicate other conditions. Contact a Bookimed coordinator to consult with a liver cancer oncologist. Our medical advisors are available to assist you, either online or offline, based on your preference.
How Is Liver Cancer Staged?
The Barcelona Clinic Liver Cancer (BCLC) system is a widely used method. It categorizes liver tumors based on several factors, such as:
-
Tumor size and number of tumors;
-
Preserved liver function;
-
Presence of vascular invasion (whether cancer has spread to blood vessels).
The BCLC staging system has five stages:
-
🟡 stage 0: very early;
-
🟡 stage A: early;
-
🟡 stage B: intermediate;
-
🟡 stage C: advanced;
-
🟡 stage D: end-stage.
What Are the Treatment Approaches?
Every patient needs a personalized treatment plan according to the cancer's stage, severity of symptoms, etc. The National Cancer Institute recommends the following treatment options:
|
Therapy |
Options |
Benefits |
Risks/side effects |
|
Complete removal of tumor (hepatectomy), a portion of the liver (resection), or performing a liver transplant in suitable cases. |
Removing the tumor in the early stages. |
Bleeding, infection, and damage to surrounding organs. |
|
|
Liver ablation |
A minimally invasive technique that destroys cancer cells using heat, radiofrequency, or freezing.
|
Allows for faster recovery and fewer complications compared to open surgery. It can be effective for small, localized tumors. |
Pain, bleeding, and infection. |
|
This is for patients without metastases unsuitable for surgery or ablation. The doctor inserts a catheter into the hepatic artery to stop the blood supply of hepatocellular carcinoma. |
Reduces blood flow to the tumor, potentially slowing its growth and minimizing symptoms. |
Indirect damage of healthy tissues due to intended blockage of blood vessels. |
|
|
Drugs such as Gemzar or Eloxatin can be used to treat liver cancer. Although most chemo medicines do not have a significant effect on liver tumors, doctors use them in combination with other treatments. |
Clears out mutated cells, controlling cancer spread. |
Nausea, vomiting, hair loss, and fatigue. |
|
|
Radiation therapy |
The external device sends high-energy X-rays toward the damaged area.
|
Quickly destroying the malignant area, reducing the potential of cancer spread. |
Fatigue, skin irritation, and digestive problems. |
|
Drugs like bevacizumab, cabozantinib, and lenvatinib attack specific tumor cells. They block critical proteins for cell growth inducing remission. |
Selectively targets cancer cells, minimizing damage to healthy tissues. |
High blood pressure, fatigue, and skin problems. |
How to Choose Treatment Based on Cancer's Stage?
Here's a breakdown of hepatocellular carcinoma stages alongside the suitable plans:
|
Stage |
Definition |
BCLC group |
Treatment Method |
|
Localized |
The cancer is confined to the liver. |
0, A, and B. |
|
|
Locally advanced |
The cancer has not spread to distant organs but cannot be safely removed by surgery. |
C |
Chemotherapy, proton therapy, and targeted therapies. |
|
Metastatic |
The cancer has spread to distant parts of the body. |
D |
Palliative treatment strategy. |
|
Recurrent |
The cancer has returned after initial treatment. |
- |
Combination of therapies, depending on the severity of symptoms and test results. |
Some patients opt to participate in clinical trials. They can benefit from testing a new drug for free or try out new experimental treatments.
