Introduction

Being told that you have liver cancer is naturally distressing, but being given a cancer diagnosis with a specific stage (i.e. stage 1, 2, 3, or 4) creates a new level of worry. Does a higher stage indicate a poorer prognosis?

Not always.

Liver cancer staging provides the medical community with the size of the cancer, if it has invaded blood vessels and lymph nodes, and if it has spread to other organs. Most importantly, staging outlines the possibilities for treatment.

Cancer staging is comparable to a road map. It indicates the location of the disease to the medical team and aids in the decision of the best route to take toward treatment.

Learn what Stage 1 to Stage 4 liver cancer means, including treatment, survival factors, transplantation, and how to choose the best liver transplant surgeon in India.

This article focuses on hepatocellular carcinoma (HCC), the most common type of primary liver cancer in adults. Your treatment plan will be individualized based on things such as your liver function, your overall health, the location of the tumour, and other factors.

1. What Does Liver Cancer Staging Mean?

When talking about liver cancer, staging refers to how advanced or widespread the cancer is.

For hepatocellular carcinoma, the TNM staging system considers the size of the tumor (T), if the cancer has spread to lymph nodes (N), and if it has spread to other organs (M).

A cancer diagnosis using the TNM system can be assigned one of several stages, based on the combination of the findings.

In the case of liver cancer, it is also important to consider how well the liver is functioning. A person can have a small tumor, but if a large portion of the liver tissue is damaged, the cancer treatment options are still quite limited.

Because of this, on top of the TNM system, doctors also use the Barcelona Clinic Liver Cancer (BCLC) classification and the Child-Pugh score.

2. How Doctors Determine the Stage

Before deciding on treatment, doctors may request a battery of tests.

These can include ultrasounds, CT scans, MRIs, blood tests, and assessments of liver function. In some cases, a biopsy may be needed.

Doctors consider many factors when attempting to understand a tumor. These can include whether the tumor has invaded blood vessels, how many tumors there are, and whether cancer has spread beyond the liver.

Of course, the health of the patient is also important. Someone with good health may be able to tolerate major surgery better than someone with cirrhosis and other health problems.

Because of all this, two patients with similar tumors may be given very different treatment options.

3. Stage 1 Liver Cancer

Generally speaking, Stage 1 liver cancer refers to cancer that is still confined to the liver.

According to the AJCC, Stage IA consists of a single liver tumor that is 2 cm or less and has not invaded blood vessels. For Stage IB, a tumor that is larger than 2 cm and has not invaded blood vessels is considered.

This is considered a better situation since cancer has not spread to lymph nodes or other organs.

Treatment for Stage 1

Tumor location and liver function will determine the options available to a patient. These may include:

• Surgical removal of the tumor (or part of the liver)
• Liver transplant
• Ablation of the tumor, using radiofrequency or microwave energy

For a patient with good liver function and a tumor that can be safely removed, surgical resection may be the best option.

In cases of significant cirrhosis or other scenarios where the partial removal of liver tissue is not an option, liver transplantation may be the only curative option.

Early diagnosis can significantly impact the patient’s treatment options because there may be several available options.

4. Stage 2 Liver Cancer

Stage 2 liver cancer describes a cancer that has grown beyond the first tumor and may have invaded blood vessels and/or involve multiple tumors in the liver.

Examples of Stage II liver cancer include a single tumor that is larger than 2 centimeters and has invaded blood vessels, or multiple liver tumors with the largest being less than 5 centimeters.

The tumor burden and the functional capacity of the remaining liver will dictate the available treatment options.

Possible Treatments

Given the situation, the following treatments may be considered:

• Surgical resection
• Liver transplantation in properly selected patients
• Ablation
• Transarterial treatments
• Radiation-based treatments
• Other liver-directed therapies

Not all Stage 2 cancers are resectable. It depends on the number of tumors, their location, involvement of blood vessels, and the liver’s functional capacity.

5. Stage 3 Liver Cancer

Stage 3 describes more locally advanced disease.

The AJCC classification breaks it down into Stage IIIA and Stage IIIB.

Stage IIIA describes multiple liver tumors with at least one measuring more than 5 centimeters. Stage IIIB describes tumor invasion into a major branch of the portal or hepatic vein, or direct invasion into nearby structures.

At this stage, the treatment options become more complex.

Can Stage 3 Liver Cancer Be Treated?

Yes, in certain situations.

Being at Stage 3 does not preclude treatment options. There are strategies to control or reduce the cancer and, in specific cases, make a patient a candidate for a more definitive treatment.

Examples of strategies include:

• Embolization
• Ablation
• Radiation therapy
• Systemic medication
• Immunotherapy
• Targeted therapy
• Selective surgical interventions

In some patients, cancer can be “downstaged.” This means that the cancer is treated to a degree that allows it to meet the criteria for a more definitive treatment, such as transplantation.

However, determining eligibility for a transplant is individualized, taking into account other criteria, tumor biology, liver function, and the patient’s overall health.

6. Liver Cancer, Stage 4

Stage 4 liver cancer indicates an advanced stage of the disease.

This stage is further classified into Stages IVA and IVB.

In Stage IVA, cancer is found to have spread to nearby lymph nodes, but not to other distant organs.

In Stage IVB, cancer has spread to other distant organs and tissues.

Cancer can spread to the lungs and bones, for example.

Treatment Options for Stage 4 Liver Cancer

In a situation where liver cancer has spread to other organs, the main treatment approach would not generally be to remove the liver cancer tumors surgically.

In such a situation, the treatment team may consider systemic treatments to control the cancer. The cancer may be treated with immunotherapy or targeted medications, for example.

Radiation therapy may be used to treat cancer in a specific area or to control cancer symptoms.

The goal of treatment is to slow the growth of cancer, lessen symptoms, improve quality of life, and potentially extend survival.

7. Liver Cancer Treatment by Stage

No treatment is the same for every person with liver cancer.

A simplified version of the different treatment options is as follows:

• Stage 1: Treatments that may cure liver cancer include resection, ablation, or liver transplantation.
• Stage 2: Treatments may include liver transplantation, ablation, embolization, or other liver-directed treatments.
• Stage 3: Treatments may include liver-directed procedures, systemic therapy, radiation, and surgery.
• Stage 4: Systemic therapy is the main treatment focus, and other therapies may be used to control symptoms and localized disease.

The treatment plan should be created by a multidisciplinary team, not based solely on the cancer stage.

8. When Is Liver Transplantation Considered?

Liver transplantation is a treatment option for people with liver cancer who also have significant disease of the liver.

A transplant removes the cancerous liver and replaces it with a healthy donor liver. This can also treat the underlying disease of the liver.

The Milan criteria is a framework that is often discussed for selecting transplant patients. This framework includes a single liver cancer tumor that is no larger than 5 centimeters, or up to a maximum of three liver cancer tumors with the largest tumor no bigger than 3 centimeters, with no cancer spread.

Transplant programs may also consider patients outside of this framework, particularly patients who have undergone treatment and responded well to downstaging.

When thinking about transplantation, it is important to consider the experience of the transplant center and the specialist.

When considering the best liver transplant surgeon in India, there are many factors to consider beyond what is presented in marketing material. These include the transplant center’s infrastructure, multidisciplinary support, experience, outcomes, and whether the team regularly manages complex liver cancer cases.

9. What Influences Liver Cancer Survival?

Cancer stage is important, but there are other factors that influence cancer survival.

These factors may include, but are not limited to:

• Tumor size and number
• Blood vessel invasion
• Cancer metastasis
• Liver function
• Cirrhosis
• General health
• Response to treatment
• Ability to receive potentially curative treatment
• Recurrence after treatment

Using the example provided, two patients with the same cancer stage may have different survival outcomes. One patient may have well-preserved liver function, while the other patient may have severely cirrhotic liver function.

Therefore, online survival statistics should be viewed as generalized information, not individualized prediction tools.

10. Liver Cancer Survival Rates: What Do the Numbers Mean?

Survival statistics are broadly developed and may provide limited information, but these statistics can still be useful.

The American Cancer Society, using SEER data from 2014 to 2020, reports a 5-year relative survival rate of 37% for localized liver cancer, 13% for regional cancer, and 3% for distant cancer.

Survival rates for SEER groups may differ from AJCC stage groupings because SEER cancers are grouped by localized, regional, and distant spread.

Most importantly, available treatments are improving. Survival rates are based on patient groups from previously studied time periods and cannot be used to predict the survival of an individual.

For certain patients who undergo liver transplantation for early liver cancer, 5-year survival rates may be higher than general population statistics for liver cancer.

11. The Location of the Cancer Is Important, but So Is Liver Function

The liver is the site of the cancer, but the liver also needs to remain functional during treatment.

Many patients with liver cancer also have cirrhosis or chronic liver disease.

There are multiple ways to evaluate liver function, including but not limited to:

• Bilirubin levels
• Albumin levels
• Clotting function
• Ascites
• Overall liver reserve

This can impact the safety of a surgical procedure and the tolerance of other treatments.

If the liver is compared to a house and the cancer is the visible problem, such as a tumor on the roof, the liver may also have a damaged foundation. Removing the tumor does not solve the problem if too much of the liver is removed.

This is one of many reasons the entire liver needs to be taken into account when planning treatment, not just the tumor.

12. Finding the Right Liver Cancer and Transplant Team

When you or a family member is diagnosed with liver cancer, selecting the appropriate medical team may feel like one of the most important decisions you will ever make.

Here are some questions to ask:

• How much liver transplant experience does the surgeon have?
• Does the hospital have a liver transplant program?
• Does the team treat liver cancer as well as cirrhosis and other liver conditions?
• Are hepatologists, oncologists, radiologists, interventional radiologists, and transplant specialists part of the team?
• Will the team consider other treatments and counsel you on your options?

When looking for a liver transplant surgeon in India, it is wise to consider the center and the team’s experience with your specific condition beyond advertisements and online rankings.

A second opinion from a transplant or liver cancer center is warranted when major surgery or a transplant is being considered.

13. Is There Hope for Someone With Late-Stage Liver Cancer?

Just because someone has late-stage liver cancer does not mean there is no option for treatment.

The goal of treatment for someone with late-stage liver cancer is often to control the cancer and improve the person’s quality of life.

There are newer treatments for liver cancers that include systemic therapies such as immunotherapy and targeted therapies.

Treatment for liver cancer is individualized based on the person’s liver function, other medical conditions, tumor characteristics, and overall health and wellness.

It may also be possible for a person to gain access to newer treatments through clinical trials.

14. What to Expect After Treatment

Even though a person may have received treatment for liver cancer, it does not necessarily mean the person is cancer-free.

Liver cancer has a risk of recurrence, so regular follow-up is important.

To monitor for a return of the cancer, the person may need to undergo follow-up testing, which may include imaging and blood tests to assess liver function and identify possible complications of chronic liver disease.

The management of cirrhosis must continue for patients with cirrhosis.

Alcohol use, medications, nutrition, viral hepatitis, lifestyle, and other medical issues should be discussed with the healthcare team.

15. Conclusion

The degree of cancer spread from Stage 1 to Stage 4 liver cancer does not necessarily determine an individual’s outlook.

Early-stage cancer may be treated with surgery, ablation, or liver transplantation. More advanced cancer may be treated with a variety of options, including liver-directed therapy, systemic therapy, immunotherapy, and palliative care.

A multidisciplinary liver cancer and transplant team may evaluate whether a liver transplant is appropriate. However, do not assume that a “stage number” alone determines whether a liver transplant is possible or is the only option.

Tumor burden and characteristics, an individual’s overall health and liver function, response to treatment, and other available treatment options should also be considered.

Frequently Asked Questions

1. Is Stage 1 Liver Cancer Curable?

Possibly. Stage 1 liver cancer may be cured with surgery, ablation, or a liver transplant if the tumor is amenable to those treatments and liver function is adequate.

2. Is Stage 4 Liver Cancer Always Terminal?

No. Although liver cancer is at an advanced stage, there may be treatments to control the cancer, improve symptoms, and potentially improve overall survival.

3. Can a Patient With Stage 3 Liver Cancer Get a Liver Transplant?

Carefully selected patients can potentially be considered for transplantation if there is a strong possibility that the cancer can be reduced to acceptable limits with available treatment.

The decision will be based on the extent of the tumor, the patient’s response to treatment, liver function, overall health, and the transplant center’s evaluation.

4. Is the Stage of Liver Cancer Related to Survival?

Yes, but it is not the only factor that matters. Liver function, cirrhosis, tumor biology, general health, treatment response, and access to quality cancer care can all influence survival.

5. How Can I Identify the Best Liver Transplant Surgeon in India?

Find a surgeon with substantial experience in both liver transplantation and liver cancer surgery who works within a multidisciplinary transplant team.

The center should have appropriate transplant experience, infrastructure, transplant services, and postoperative care. You should also consider how well the team handles your specific medical condition, rather than relying only on rankings or promotional claims.
