Obsolete Adult Primary Liver Cancer

Obsolete adult primary liver cancer refers to an outdated term for a type of liver cancer that was once considered resectable (removable) in adults. This term is no longer commonly used in modern medical practice.

Characteristics

• Localized: The cancer was confined to the liver, with no evidence of spread to other parts of the body.
• Resectable: The tumor could be surgically removed, potentially offering a cure or significant improvement in prognosis.
• Adult primary liver carcinoma: This term is often used interchangeably with obsolete adult primary liver cancer.

Current Understanding

The current understanding of liver cancer has evolved significantly since the term "obsolete adult primary liver cancer" was used. Modern medical practice focuses on more accurate and descriptive terms, such as hepatocellular carcinoma (HCC) or liver adenocarcinoma.

Early Signs and Symptoms

In the early stages, primary liver cancer often does not cause any noticeable symptoms. However, as the tumor grows, it may start to produce some warning signs. According to various medical sources [1][2][3], these can include:

• Unintended weight loss
• Loss of appetite
• Upper abdominal pain or discomfort
• Nausea and vomiting
• General weakness and fatigue

Later Signs and Symptoms

As the disease progresses, more pronounced symptoms may appear. These can include:

• Abdominal swelling or bloating
• Jaundice (yellowing of the skin and eyes)
• White, chalky stools
• Pain in the right side of the upper abdomen or around the right shoulder blade

Importance of Early Detection

It's essential to note that these symptoms often do not appear until the later stages of primary liver cancer. However, if you experience any unusual symptoms, it's crucial to consult a doctor promptly [4]. Early detection and treatment can significantly improve the chances of successful treatment.

Diagnostic Tests for Obsolete Adult Primary Liver Cancer

The diagnostic tests for obsolete adult primary liver cancer have evolved over time, and some methods are no longer used today. However, understanding the historical context can provide valuable insights into the development of modern diagnostic techniques.

• Blood tests: Blood tests were once a common method to diagnose liver cancer, particularly in the past (1). These tests could reveal abnormalities in liver function, such as elevated levels of liver enzymes and proteins (5).
• Imaging scans: Imaging scans, including ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI), have been used for decades to diagnose liver cancer (7, 8, 11). These scans can create detailed pictures of the liver, helping doctors identify tumors.
• Liver biopsy: A liver biopsy was once considered a definitive diagnostic test for liver cancer (9). However, with advancements in imaging technology and blood tests, this invasive procedure is now used less frequently.

Current Diagnostic Tests

While these obsolete methods are no longer widely used, they have contributed to the development of modern diagnostic techniques. Today, the following tests are commonly used to diagnose adult primary liver cancer:

• CT scans: CT scans remain a primary test for diagnosing liver cancer (11).
• MRI scans: MRI scans are also used to diagnose and stage liver cancer (8).
• Blood tests: Blood tests continue to play a role in diagnosing liver cancer, particularly in monitoring disease progression (5).

Treatment Options for Obsolete Adult Primary Liver Cancer

While modern treatments like targeted therapy and immunotherapy have become more prevalent, there are still some older drug treatment options that were used to treat adult primary liver cancer in the past. These include:

• Sorafenib (Nexavar): This was one of the first drugs approved for the treatment of advanced liver cancer [5]. Although it's not as commonly used today, sorafenib can still be effective in slowing down tumor growth and improving survival rates.
• Lenvatinib (Lenvima): Another older drug that was approved for the treatment of advanced liver cancer is lenvatinib. It works by targeting specific proteins on cancer cells to slow down their growth [5].
• Aflibercept: This is a protein-based therapy that was used in combination with other treatments to target cancer cells and slow down tumor growth.
• Bevacizumab: This is a monoclonal antibody that targets vascular endothelial growth factor (VEGF), which can help to slow down tumor growth.

Important Considerations

It's essential to note that these older drug treatment options may not be as effective or widely available as modern treatments like targeted therapy and immunotherapy. Additionally, the side effects of these older drugs can be more severe than those associated with newer treatments.

• [5] Sorafenib (Nexavar) and lenvatinib (Lenvima)​​ One of these drugs can be used as the first treatment for liver cancer if it cannot be treated by surgery or other means.
• [6] It is typically used to treat inoperable primary liver cancer. Sorafenib does not make many liver cancers shrink, but it slows the growth of tumors and has been shown to improve survival rates.
• [8] Treatment options might include ablation, embolization, or both for the liver tumor(s). Other options may include targeted therapy, immunotherapy, chemotherapy, and older drug treatments like sorafenib and lenvatinib.

The differential diagnosis of primary liver cancer in adults has evolved over time, and certain types of liver cancer that were once common are now considered rare or obsolete. Here are some examples:

• Hepatoblastoma: This is a rare malignant tumor of the liver that primarily affects children, but it can also occur in adults. However, it is extremely uncommon in adults and is usually associated with a poor prognosis [1].
• Fibrolamellar hepatocellular carcinoma (FL-HCC): This is a rare subtype of hepatocellular carcinoma (HCC) that typically affects young adults without underlying liver disease. FL-HCC has a distinct histological appearance and tends to have a better prognosis than conventional HCC [2].
• Undifferentiated embryonal sarcoma (UES): This is a rare and aggressive tumor of the liver that primarily affects children, but it can also occur in adults. UES is characterized by its undifferentiated morphology and rapid growth rate, making it challenging to diagnose and treat [3].

It's essential to note that these types of liver cancer are now considered rare or obsolete due to advances in diagnostic techniques and a better understanding of the underlying causes of primary liver cancer.

In recent years, the incidence of certain types of liver cancer has decreased, while others have increased. For example:

• Hepatocellular carcinoma (HCC): This is still the most common type of primary liver cancer in adults, particularly those with underlying liver disease such as cirrhosis or chronic hepatitis [4].
• Cholangiocarcinoma (CCA): This is a rare but aggressive tumor of the bile ducts that can occur in any part of the biliary tree. CCA has a poor prognosis and is often diagnosed at an advanced stage [5].

In summary, while certain types of liver cancer are now considered obsolete or rare, others continue to pose significant diagnostic challenges due to their rarity and aggressive nature.
