Important features that guide treatment include:

size
spread (stage)
involvement of liver vessels
presence of a tumor capsule
presence of extrahepatic metastases
presence of daughter nodules
vascularity of the tumorMRI is the best imaging method to detect the presence of a tumor capsule. The most common sites of metastasis are the lung, abdominal lymph nodes, and bone. Prevention
Since hepatitis B and C are some of the main causes of hepatocellular carcinoma, prevention of infection is key to then prevent HCC. Thus, childhood vaccination against hepatitis B may reduce the risk of liver cancer in the future. In the case of patients with cirrhosis, alcohol consumption is to be avoided. Also, screening for hemochromatosis may be beneficial for some patients. Whether screening those with chronic liver disease for HCC improves outcomes is unclear. Treatment
Treatment of hepatocellular carcinoma varies by the stage of disease, a persons likelihood to tolerate surgery, and availability of liver transplant:

Curative intention: for limited disease, when the cancer is limited to one or more areas of within the liver, surgically removing the malignant cells may be curative. This may be accomplished by resection the affected portion of the liver (partial hepatectomy) or in some cases by orthotopic liver transplantation of the entire organ. "Bridging" intention: for limited disease which qualifies for potential liver transplantation, the person may undergo targeted treatment of some or all of the known tumor while waiting for a donor organ to become available. "Downstaging" intention: for moderately advanced disease which has not spread beyond the liver, but is too advanced to qualify for curative treatment.
Heart failure is often a concern because the inferior vena cava is disrupted due to the inappropriate morphology of the left ventricle to support the vena cava. Conductive nodes and tissues
Abnormal development of the heart results in impaired doubles of conductive nodes, as well as faulty electrical fibers throughout the ventricles. Individuals with right atrial isomerism develop two sinoatrial nodes, as they have 2 mirrored right atria, whereas those with left atrial isomerism fail to develop a sinus node at all. Thus, patients with left atrial isomerism are more likely to experience atrial fibrillation, or irregular rapid heart beat, and abnormal heart rhythm, known as atrial flutter. Development of the atrioventricular node and bundle of His largely depends on physiological looping of the ventricles. Abnormal looping of the ventricles contributes to arrhythmia and heart block in fetuses. Bronchial tree and lungs
Isomerism of the bronchial tree is not typically damaging and presents no significant clinical complications. Pulmonary valve stenosis results in issues of blood flow to the lungs. Abdominal organs
Abdominal organs, including the liver, stomach, intestinal tract, and spleen may be randomly arranged throughout the left-right axis of the body. Distribution of these organs largely dictates treatment, clinical outcomes, and further evaluation. The liver is typically symmetrical across the left-right axis in patients with situs ambiguus, which is abnormal. A majority of left atrial isomeric patients have defects throughout the biliary tree, which is responsible for bile production, even when the gall bladder is functional and morphologically normal.
