Introduction

Liver cancer is a challenging diagnosis, but surgery offers a critical path to treatment, with options ranging from partial hepatectomy (procedure to remove part or all of the liver) to liver transplantation, ablation (removal of a part of biological tissue), and embolization therapies. Each approach has specific indications and benefits, making it essential for patients to understand their choices. This article provides an overview of these surgical options and the necessary pre- and post-surgical care to support informed decision-making.

Understanding liver cancer

Liver cancer is categorised into primary (originating in the liver, e.g., Hepatocellular Carcinoma) and secondary (cancer spread to the liver from other body parts). Primary liver cancer is often linked to chronic liver conditions like hepatitis or cirrhosis, while secondary liver cancer is more common.^1,2

• Key risk factors: Chronic viral hepatitis (B or C), cirrhosis, heavy alcohol use, obesity, and aflatoxin exposure are major risk factors that influence liver cancer development^1,2
• Symptoms and diagnosis: Common symptoms include unexplained weight loss, abdominal pain, jaundice, and fatigue. Diagnosis typically involves imaging tests (like ultrasound or CT scans), blood tests for alpha-fetoprotein (AFP) levels, and sometimes a biopsy to confirm the cancer type and guide treatment decisions, including surgery^1,2

When is surgery recommended?

Surgery is most effective when the cancer is detected at an early stage, is localised within the liver, and the liver is healthy enough to tolerate the procedure. Overall patient health, including heart and lung function, is also assessed. Staging helps determine the feasibility of surgery, with early-stage cancers being the most suitable for resection or transplantation.^1,2

Types of liver cancer surgeries

Liver cancer surgeries are critical treatment options that can potentially cure or significantly control the disease, depending on the cancer stage, location, and overall liver function. Here’s an in-depth look at the primary surgical options available:

1. Partial hepatectomy (liver resection)

This procedure involves the surgical removal of the liver section containing the tumour. The extent of resection can vary, from removing a small wedge of tissue to an entire lobe (lobectomy) of the liver, depending on the tumour's size, number, and location.^3,4,5,6

• Suitability:
  This surgery is ideal for patients with localised tumours confined to a specific part of the liver and whose liver function is otherwise good. It is often considered when there is a single tumour without invasion into major blood vessels. However, it is less suitable for patients with severe cirrhosis or multiple tumours spread across the liver, as these conditions can increase the risks associated with surgery^3,4,5,6
• Potential risks and benefits:
  • Benefits: Offers the potential for a cure if the cancer is fully removed and the remaining liver can regenerate, restoring liver function^3,4,5,6
  • Risks: Include significant bleeding due to the liver's rich blood supply, infection, liver failure, and potential complications from general anaesthesia^3,4,5,6

2. Liver transplantation

For patients where resection is not viable, a more extensive approach may be considered. This procedure replaces the entire diseased liver with a healthy liver from a donor. This option is particularly considered for patients who have small tumours that cannot be removed by resection due to location or underlying liver damage.^3,4,5,6

• Suitability:
  Ideal for patients with early-stage liver cancer that meets specific criteria, such as the Milan Criteria (one tumour ≤ 5 cm or up to three tumours all ≤ 3 cm), and who do not have cancer that has spread beyond the liver. Liver transplantation is also suitable for patients with severely compromised liver function due to cirrhosis, addressing both the cancer and the underlying liver condition^3,4,5,6
• Challenges:
  The primary challenge is the availability of donor organs, which can lead to long waiting times. Patients must also be in good enough health to undergo the transplant surgery and manage lifelong immunosuppressive medications to prevent organ rejection^3,4,5,6
• Risks and benefits:
  • Benefits: Provides a potential cure by treating both the liver cancer and the associated underlying liver disease^3,4,5,6
  • Risks: Include rejection of the new liver, infections, complications from surgery, and the need for long-term immunosuppressive therapy^3,4,5,6

3. Ablation techniques

When traditional surgery is not suitable, less invasive alternatives like ablation can provide effective options. These are minimally invasive procedures that destroy cancer cells directly within the liver without removing them surgically. Common methods include radiofrequency ablation (RFA), microwave ablation, and ethanol (alcohol) ablation.^3,4,5,6

• Suitability:
  These techniques are ideal for patients with small tumours (usually less than 3 cm) who are not candidates for surgery due to poor liver function or other health issues. Ablation can also serve as a bridging therapy while waiting for a liver transplant^3,4,5,6
• Benefits and limitations:
  • Benefits: These procedures are less invasive than surgery, have shorter recovery times, and can be repeated if necessary^3,4,5,6
  • Limitations: Ablation is generally less effective for larger tumours or those near major blood vessels due to the heat-sink effect, where blood flow can cool the area and reduce the effectiveness of the ablation^3,4,5,6

4. Embolization therapies types

Another alternative for inoperable liver cancer involves cutting off the tumour's blood supply through embolization. These therapies work by obstructing the tumour's blood supply, effectively starving the cancer cells of oxygen and nutrients while delivering chemotherapy or radiation directly to the tumour site.^3,4,5,6

Transarterial Chemoembolization (TACE): Combines the delivery of chemotherapy directly to the liver tumour through the hepatic artery with embolization, blocking the artery to reduce blood flow to the tumour and enhance the chemotherapy's effect.^5,6,7,8

Radioembolization (Y-90): Uses tiny beads loaded with radioactive material (Yttrium-90) to deliver targeted radiation therapy directly to the tumour.^5,6,7,8

• Suitability and effectiveness: Suitable for patients with larger tumours, multiple tumours, or when surgery is not feasible. Embolization can effectively control symptoms and reduce tumour size in preparation for other treatments, such as surgery or transplantation^5,6,7,8
• Benefits and limitations:
  • Benefits: Can shrink tumours, reduce symptoms, and improve quality of life. These therapies are often used as palliative care or as a bridge to surgery or transplant^5,6,7,8
  • Limitations: May not be curative on their own, especially for more advanced cancers, and can have side effects such as post-embolization syndrome, which includes pain, fever, and nausea^5,6,7,8

5. Emerging surgical techniques

In recent years, technological advancements have led to emerging surgical techniques that further improve patient outcomes.

Robotic-assisted surgery: Uses robotic systems to perform liver resections with precision, potentially reducing recovery time and surgical risks.^4,7,8

Laparoscopic surgery: A minimally invasive approach that uses small incisions and a camera to guide the removal of liver tumours, offering benefits like shorter hospital stays and quicker recovery compared to open surgery.^4,7,8

Preparing for surgery

Pre-surgical evaluations

Before liver cancer surgery, a series of evaluations is conducted to ensure patients are suitable candidates:^5,9,10

• Imaging and tests: CT scans, MRIs, and ultrasounds are used to determine the tumour’s size, location, and extent. Blood tests, including liver function tests, help assess the liver’s ability to withstand surgery^5,9,10
• Overall health assessment: A comprehensive evaluation of the patient’s overall health, including heart and lung function, identifies potential risks and confirms surgical fitness^5,9,10

Importance of multidisciplinary care

Utilising a multidisciplinary team (MDT) approach is essential for achieving the best possible surgical outcomes:

• Team composition: The MDT typically includes liver surgeons, oncologists, hepatologists, radiologists, dietitians, and specialist nurses. Each member plays a role in developing a personalised care plan that meets the patient’s specific needs^5,9,10
• Coordinated planning: The team collaborates to plan the surgery, manage existing health conditions, and anticipate potential complications, ensuring a comprehensive and coordinated approach to care^5,9,10

Patient education and expectations

Proper education and setting realistic expectations are essential parts of surgical preparation:

• Pre-surgery counselling: Patients receive detailed information about what to expect before, during, and after surgery, including potential risks, benefits, and the objectives of the procedure^5,9,10
• Lifestyle adjustments: Patients may be advised to quit smoking, improve their diet, and increase physical activity to boost surgical readiness and support recovery^5,9,10
• Psychological support: Access to counselling or support groups can help patients manage anxiety and stress associated with surgery^5,9,10

Post-surgery considerations

Recovery process 

The recovery phase is crucial for successful healing and involves several key components:

• Hospital stay and initial recovery: Recovery duration varies by surgery type. Patients undergoing partial hepatectomy typically stay in the hospital for 5 to 10 days, while liver transplant patients may require longer stays. Minimally invasive procedures, like ablation or embolization, usually involve shorter hospital stays^5,9,10
• Home recovery: Home recovery can take weeks to months and focuses on pain management, wound care, and gradually increasing physical activity to regain strength and mobility^5,9,10

Potential complications

Understanding potential complications is important for patients and caregivers:^5,9,10

• Infection: A common post-surgery risk; symptoms like fever, redness, or swelling at the incision site need quick treatment
• Bleeding: Due to the liver’s extensive blood supply, bleeding is a significant risk, especially following resections or transplants
• Liver failure: If the remaining liver cannot function adequately, there is a risk of liver failure, particularly in patients with pre-existing liver conditions
• Organ rejection: Specific to liver transplants, where the immune system may attack the new liver, necessitating close monitoring and lifelong immunosuppressive medication

Follow-up care and monitoring

Continued care and monitoring are essential to ensure a successful recovery and early detection of any issues:^5,9,10

• Regular appointments: Follow-up care involves routine visits for scans and blood tests to monitor liver function and watch for cancer returning
• Lifestyle maintenance: Patients are encouraged to maintain a healthy lifestyle, including avoiding alcohol, eating a balanced diet, and managing other health conditions to support liver health
• Long-term monitoring: For transplant patients, ongoing assessments of liver function and medication adjustments are necessary to prevent organ rejection and maintain overall health

FAQs

What are the latest advancements in liver cancer surgery?

Recent advancements in liver cancer surgery include the adoption of robotic-assisted and laparoscopic techniques. Robotic-assisted surgery offers enhanced precision, smaller incisions, and faster recovery times, making procedures less invasive. Laparoscopic surgery utilises small incisions and a camera to guide the removal of tumours, reducing trauma compared to traditional open surgery. Additionally, advanced imaging technologies, such as 3D imaging and intraoperative ultrasound, provide surgeons with detailed views of the liver and tumours, improving the accuracy of resections. These innovations are improving surgical outcomes and expanding treatment options for patients with liver cancer.^2,3,4,6

How does liver function affect surgical options for liver cancer?

Liver function is a crucial factor in determining surgical options for liver cancer. Surgeries like partial hepatectomy require good liver function as the remaining liver must regenerate and continue to perform essential functions after resection. Patients with compromised liver function, such as those with severe cirrhosis, may face higher risks of liver failure from major surgeries. In these cases, less invasive options like ablation or embolization, which impose less stress on the liver, may be preferable. For patients with significantly impaired liver function but localised cancer, a liver transplant may be the best option.^4,8

What are the chances of liver cancer recurrence after surgery?

The likelihood of liver cancer recurrence after surgery depends on factors like cancer stage, type, extent of resection, and liver health. Recurrence is more probable if the cancer is not entirely removed or if the patient has underlying conditions like cirrhosis that continue to damage the liver. Consistent follow-up with imaging and blood tests is essential for early detection of recurrence. If the cancer returns, additional treatments such as ablation, chemotherapy, or further surgery may be necessary to manage the disease.^4,8

Can lifestyle changes impact the success of liver cancer surgery?

Yes, lifestyle changes can significantly improve the success of liver cancer surgery. Quitting smoking, reducing alcohol intake, maintaining a healthy weight, and following a nutritious diet can enhance liver health and support recovery. Managing other conditions, like diabetes or hypertension, also reduces surgical risks. Patients who adopt positive lifestyle changes often experience better outcomes, faster recoveries, and a reduced risk of cancer recurrence.^2,3,5

What happens if a liver transplant patient experiences organ rejection?

Organ rejection occurs when the patient’s immune system attacks the transplanted liver, mistaking it for a foreign threat. To prevent rejection, patients are prescribed lifelong immunosuppressive medications to dampen the immune response. Signs of rejection include abnormal liver function tests, fever, jaundice, and pain near the liver. Regular monitoring and prompt adjustment of immunosuppressive therapy can manage rejection. In severe cases, additional treatments such as high-dose steroids or other immunosuppressive drugs may be required to control the immune response.^6,9
