Bavarian Liver Cancer: Unique Factors And Famous Cases

Bavarian Leberkäse, or liver cheese in German, is a speciality food from southern Germany, Austria, and parts of Switzerland. Despite its name, the Bavarian variety does not contain any liver or cheese, unlike other Leberkäse varieties which must contain at least 4% liver and sometimes include cheese. Bavarian Leberkäse is made from beef, pork, and bacon, though other variations may use different types of meat or include additional ingredients such as cheese or chillies. It is typically baked in a loaf tin until a crunchy brown crust forms and is often served in a bread roll with mustard or pickles.

Hepatocellular carcinoma (HCC) is the most common form of liver cancer

Liver cancer is a life-threatening illness and one of the fastest-growing types of cancer in the United States. It is caused by cells in the liver growing out of control. The liver is an essential organ with many functions, including removing waste products and filtering chemicals in food, alcohol, medications, and blood.

HCC typically presents with symptoms such as an abdominal mass, abdominal pain, vomiting, anaemia, back pain, jaundice, itching, weight loss, and fever. Diagnosis is made through blood tests, medical imaging, and tissue biopsy. Treatment options include surgery, targeted therapy, and radiation therapy.

While HCC is the most frequent form of liver cancer, it is important to note that other types of primary liver cancer exist, such as intrahepatic cholangiocarcinoma (bile duct cancer) and angiosarcoma. These cancers have different risk factors, treatments, and prognoses.

Intrahepatic cholangiocarcinoma (bile duct cancer) accounts for 10-20% of liver cancers

Liver cancer, or hepatic cancer, is a life-threatening illness and one of the fastest-growing cancer types in the US. It is caused by something affecting the healthy liver cells' DNA, which carries the genes that tell cells how to function. There are two types of liver cancer: primary liver cancer, which starts in the liver, and secondary liver cancer, which spreads to the liver from another part of the body.

Primary liver cancer can be further divided into three types: hepatocellular carcinoma (HCC), intrahepatic cancer (IHC), and angiosarcoma. IHC, or cholangiocarcinoma, is cancer in the liver's bile ducts and accounts for about 10-20% of all primary liver cancer cases. Bile duct cancer, or cholangiocarcinoma, is a rare, aggressive form of cancer that often affects adults in their 60s or 70s. It is typically diagnosed after it has spread beyond the bile ducts, at which point it is difficult to treat and has a poor prognosis.

Cholangiocarcinoma can form in the bile ducts inside the liver (intrahepatic), just outside the liver (perihilar), or further away from the liver (distal). It is typically asymptomatic until the disease has progressed. Symptoms include abdominal pain, night sweats, weight loss, and fatigue. Risk factors for cholangiocarcinoma include long-term inflammation in the bile ducts, primary sclerosing cholangitis, ulcerative colitis, cirrhosis, hepatitis B and C, infection with certain liver flukes, and some congenital liver malformations. However, most people have no identifiable risk factors.

Treatment for cholangiocarcinoma usually involves a combination of surgery, chemotherapy, and radiation therapy. Surgery can be used to treat bile duct cancers that haven't spread, but most have already spread by the time they are diagnosed. Liver transplantation may be used as a potential cure for early-stage perihilar cholangiocarcinoma. Other treatments include radiation therapy, chemotherapy, targeted therapy, and immunotherapy. Clinical trials to improve the outcomes of cholangiocarcinoma are ongoing.

Angiosarcoma and hemangiosarcoma are rare and aggressive liver cancers

Angiosarcoma and hemangiosarcoma are rare and aggressive forms of liver cancer. They are the third most common primary liver cancer, making up 0.1-2.0% of primary liver cancer cases. These cancers arise from the endothelial layer of blood vessels in the liver. They are challenging to diagnose due to non-specific symptoms and the difficulty of differentiating them from other hepatic tumours on radiological imaging. Symptoms can include abdominal pain, weight loss, distension, jaundice, and fatigue. However, they can also be asymptomatic and discovered incidentally on imaging scans.

The prognosis for angiosarcoma and hemangiosarcoma of the liver is poor, with most individuals not surviving longer than six months after diagnosis. Even with treatment, only about 3% of patients live beyond two years. The tumours grow rapidly and metastasise easily, contributing to the poor outcomes. They are often detected on CT or MRI scans, which show focal lesions with varying signal intensities due to bleeding or tissue necrosis. A biopsy with histopathological evaluation is required for a definitive diagnosis.

While the cause of these cancers is often unknown (75% are idiopathic), they have been associated with exposure to certain substances, such as vinyl chloride, arsenic, and thorotrast (a radiocontrast agent no longer in use). Radiation exposure is also a risk factor. In adults, these tumours are more common in males, while in children, they are more prevalent in females.

Treatment options for angiosarcoma and hemangiosarcoma of the liver are limited. Surgery is the most effective approach, but it is not always feasible due to the aggressive nature of the disease. Liver transplantation is not recommended due to the high recurrence rate and rapid progression. Chemotherapy and radiation therapy have not proven effective against these cancers.

Angiosarcoma and hemangiosarcoma of the liver are rare and aggressive forms of primary liver cancer with challenging diagnostic and treatment landscapes. Early diagnosis and surgical intervention are crucial for optimising patient outcomes. However, the poor prognosis and limited treatment options underscore the need for further research and therapeutic advancements.

Liver cancer is caused by changes to DNA and is often linked to cirrhosis

Liver cancer, also known as hepatic cancer, is a life-threatening illness and one of the fastest-growing types of cancer globally, with instances of the disease increasing worldwide. It is caused by changes or mutations to DNA, which carries the genes that instruct cells on how to function. Oncogenes, for example, help cells grow and divide, while tumour suppressor genes monitor cell activity and keep cells from multiplying uncontrollably, ensuring they die when they are supposed to. When DNA mutates, cells receive new instructions, which can cause healthy liver cells to become cancerous.

The most common form of liver cancer is hepatocellular carcinoma (HCC), which accounts for approximately 75% of all primary liver cancers. HCC is caused by changes to DNA, often due to cirrhosis related to hepatitis B virus (HBV) and hepatitis C virus (HCV) infections. These viruses infect and change the DNA of liver cells, turning them cancerous. Over half of all HCC cases are caused by these viruses.

Cirrhosis, a late-stage liver disease, is the result of persistent liver damage over many years, causing healthy liver tissue to be gradually replaced by scar tissue. This scarring interferes with the liver's functioning, blocking the flow of blood and oxygen through the liver tissues. Alcohol, drugs, viruses, and metabolic factors are the most common causes of cirrhosis. It is also associated with non-alcoholic fatty liver disease, which is the result of excess fat storage in the liver due to metabolic factors such as high blood lipids, blood sugar, and blood pressure.

In addition to HBV and HCV infections, other causes of cirrhosis can lead to HCC. Alcohol intake is a significant risk factor, with individuals with alcohol-induced cirrhosis having a greater risk of developing HCC. Hereditary hemochromatosis, a condition where the body takes up and stores more iron than it needs, and primary biliary cirrhosis are also associated with HCC.

While liver cancer is a serious and life-threatening disease, healthcare providers can do more to treat it if it is caught in its early stages. Regular health check-ups and liver cancer screenings can help identify the disease early, allowing for more effective treatment options and a better prognosis.

Liver cancer is one of the fastest-growing cancer types with a poor prognosis

Liver cancer is a life-threatening illness and one of the fastest-growing cancer types, with a poor prognosis. It is the sixth-most frequent cancer globally and the fourth-leading cause of cancer-related deaths. In 2018, liver cancer was responsible for 782,000 deaths worldwide.

Liver cancer is divided into two main types: primary and secondary. Primary liver cancer originates in the liver, while secondary liver cancer occurs when cancer spreads to the liver from another part of the body. Primary liver cancer is further classified into three types: Hepatocellular Carcinoma (HCC), Intrahepatic Cancer (IHC), and Angiosarcoma. HCC is the most prevalent form, accounting for almost all liver cancer cases. IHC, a type of cholangiocarcinoma affecting the bile ducts, accounts for 10-20% of cases. Angiosarcoma is rare, comprising about 1% of primary liver cancer cases.

The prognosis for liver cancer depends on various factors, including the type, stage, and characteristics of the cancer, as well as the patient's liver function, overall health, and response to treatment. People with poor liver function due to the tumour, cirrhosis, or hepatitis often have a poor prognosis. The stage of the cancer is a critical factor, with those in the early stages having a more favourable prognosis. For instance, people with BCLC stage 0 or A liver cancer have a better prognosis than those with stage B, C, or D.

The five-year survival rates for liver cancer vary depending on the stage and treatment. For early-stage hepatocellular carcinoma (HCC), the five-year survival rate is 35%. This rate decreases to 12% for HCC that has spread to nearby tissues, organs, or lymph nodes, and only 3% for HCC that has metastasized further. For intrahepatic bile duct cancer (IHC), the five-year survival rates are 24% for cancer confined to the bile duct, 9% for cancer that has spread to nearby lymph nodes, and 2% for more advanced stages.

Successful liver transplants can cure liver cancer, but not all patients are suitable candidates for transplantation. Surgery to remove part of the liver can also improve survival rates, and patients who undergo surgery tend to live longer than those who cannot have surgery due to health reasons. Additionally, treatments such as chemotherapy, radiation therapy, immunotherapy, and targeted therapy can help manage the disease and improve prognosis.
