The prognosis for liver cancer, like most other cancers, depends strongly on how advanced the disease is when it is first diagnosed. We know about getting mammograms, Pap smears, and colonoscopies. But how many of us are familiar with early detection of liver cancer?
Most liver cancers are predictable. They start with cirrhosis, which is a scarring disorder caused by alcohol abuse, hepatitis, or other less common conditions. This is a serious condition that can cause liver failure by itself, but it can be successfully treated for many patients. References 1 – 3 recommend surveillance for liver cancer in these individuals. Ultrasound imaging and blood tests for alpha fetoprotein performed every six months can flag tumors at an early stage, when the patient has more treatment options. In a study of 1,436 patients with newly diagnosed hepatocellular carcinoma, those who had received these exams had significantly better rates of 3-year survival: 59.1 (surveillance group) versus 29.3 percent (cancer detected incidentally group).
Unfortunately, rates of liver cancer surveillance are low in the United States. A study from the Houston VA Medical Center and Baylor College of Medicine found that less than 20 percent of cirrhosis patients who developed liver cancer had received regular surveillance. Patients with higher income and those who live in urban areas are more likely to receive appropriate exams. Physicians most likely to perform surveillance are gastroenterologists, hepatologists, and those with an academic affiliation.
Cirrhosis itself may have no symptoms in the early stages. Risk factors include excessive alcohol consumption, sexual contact with someone who has hepatitis B or C infection, and contact with blood infected with one of these viruses. Less common causes of cirrhosis are autoimmune hepatitis, hemochromatosis, Wilson's disease, non-alcoholic fatty liver disease, and some medications. Liver function tests should be a part of the annual checkup for most adults, and those with known risks should be especially sure to get their checkups.
