Diagnosis
If a patient has symptoms that suggest liver cancer, the doctor performs one or more of the following procedures:
Physical exam -- The doctor feels the abdomen to check the liver, spleen, and nearby organs for any lumps or changes in their shape or size. The doctor also checks for ascites, an abnormal buildup of fluid in the abdomen. The doctor may examine the skin and eyes for signs of jaundice.
Blood tests -- Many blood tests may be used to check for liver problems. One blood test detects alpha-fetoprotein (AFP). High AFP levels could be a sign of liver cancer. Other blood tests can show how well the liver is working.
CT scan -- An x-ray machine linked to a computer takes a series of detailed pictures of the liver and other organs and blood vessels in the abdomen. The patient may receive an injection of a special dye so the liver shows up clearly in the pictures. From the CT scan, the doctor may see tumors in the liver or elsewhere in the abdomen.
Ultrasound test -- The ultrasound device uses sound waves that cannot be heard by humans. The sound waves produce a pattern of echoes as they bounce off internal organs. The echoes create a picture (sonogram) of the liver and other organs in the abdomen. Tumors may produce echoes that are different from the echoes made by healthy tissues.
MRI -- A powerful magnet linked to a computer is used to make detailed pictures of areas inside the body. These pictures are viewed on a monitor and can also be printed.
Angiogram -- For an angiogram, the patient may be in the hospital and may have anesthesia. The doctor injects dye into an artery so that the blood vessels in the liver show up on an x-ray. The angiogram can reveal a tumor in the liver.
Biopsy -- In some cases, the doctor may remove a sample of tissue. A pathologist uses a microscope to look for cancer cells in the tissue. The doctor may obtain tissue in several ways. One way is by inserting a thin needle into the liver to remove a small amount of tissue. This is called fine-needle aspiration. The doctor may use CT or ultrasound to guide the needle. Sometimes the doctor obtains a sample of tissue with a thick needle (core biopsy) or by inserting a thin, lighted tube (laparoscope) into a small incision in the abdomen. Another way is to remove tissue during an operation.
A patient who needs to have a biopsy may want to ask the doctor some of the following questions: Why do I need a biopsy? How will the biopsy affect my treatment plan? What kind of biopsy will I have? How long will it take? Will I be awake? Will it hurt? Is there a risk that the biopsy procedure will cause the cancer to spread? What are the chances of infection or bleeding after the biopsy? Are there any other risks? How soon will I know the results? If I do have cancer, who will talk with me about treatment? When?

Staging If liver cancer is diagnosed, the doctor needs to know the stage, or extent, of the disease to plan the best treatment. Staging is an attempt to find out the size of the tumor, whether the disease has spread, and if so, to what parts of the body. Careful staging shows whether the tumor can be removed with surgery. This is very important because most liver cancers cannot be removed with surgery.
The doctor may determine the stage of liver cancer at the time of diagnosis, or the patient may need more tests. These tests may include imaging tests, such as a CT scan, MRI, angiogram, or ultrasound. Imaging tests can help the doctor find out whether the liver cancer has spread. The doctor also may use a laparoscope to look directly at the liver and nearby organs.
Staging of HCC is based on four criteria: tumor size, presence of ascites, and bilirubin and albumin levels. The Okuda staging symptom is:
| Grade | Criteria | Natural History Without Treatment | | I | no positive criteria | 8 months | | II | 1 or 2 positive | 2 months | | III | 3 or 4 positive | Less than 1 month |
