What tests can detect liver cancer?

Liver cancer is a relatively serious disease, and friends are no stranger to it. The examination for this disease is relatively complicated and thorough. It is almost a systemic examination. Understanding these is actually very helpful for the treatment of the disease. Below we will introduce to you in detail some common examination items for liver cancer.

1. The most commonly used examination is liver ultrasound. Ultrasound examination is a non-invasive examination and has no adverse effects on human tissues. It is simple to operate, intuitive and accurate, low-cost, convenient and non-invasive, and widely popular. It can be used for the screening of liver cancer and follow-up after treatment.

2. CT has become an important routine means of diagnosing liver cancer. Abdominal enhanced CT scans can clearly show the size, number, shape, location, boundary, tumor blood supply, and relationship with the intrahepatic ducts of liver cancer, which is important for further clarifying the diagnosis and distinguishing it from other benign liver lesions. At the same time, it is also important to clarify the staging and grading of liver cancer, which is important for guiding treatment and judging prognosis. Image analysis software can also be used to reconstruct the various ducts in the liver, accurately track the course of blood vessels in each liver segment, the relationship between tumors and blood vessels, simulate the surgical resection plane, and calculate the volume of the pre-resected tumor and the remaining liver volume, greatly improving the safety of the operation.

3. Liver-specific MRI can improve the detection rate of small liver cancer. It is also helpful for differentiating liver cancer from focal hyperplastic nodules and hepatic adenomas, and can serve as an important supplement to CT examinations.

4. pET (positron emission tomography)-CT whole-body scan can understand the overall condition and evaluate tumor metastasis, and can more comprehensively determine the tumor stage and prognosis, but it is relatively expensive and is generally not used as the first choice.

5. Selective hepatic artery angiography is an invasive examination. Since liver cancer is rich in blood supply, mainly supplied by the hepatic artery, hepatic artery angiography can clearly show the blood supply of small liver lesions and tumors. After a clear diagnosis, iodized oil can be injected to block the tumor supply vessels to achieve the purpose of treatment. It is suitable for patients who have not been diagnosed after other examinations. Patients with hepatitis B and C should have regular checkups, and if possible, they should have annual physical examinations. Liver B-ultrasound is the most basic examination.

How to check for liver cancer

At present, the number of patients in my country accounts for more than half of the world's cases, and 55% of the world's liver cancer patients. It has become a major killer that seriously threatens the health and life of the Chinese people. Its danger should not be underestimated. Therefore, people with a high risk of liver cancer need to be vigilant to avoid developing liver cancer unknowingly. For example, patients with hepatitis B, big three Yang patients, cirrhosis patients or people with liver diseases are all high-risk groups for liver cancer. How to check whether they have liver cancer?

1. Liver function test: Liver function test can detect whether liver function is damaged and monitor changes in liver disease.

2. Ultrasound examination. Ultrasound examination is the most popular examination in my country and is a non-invasive examination. It can show the size, shape, location of the tumor, and whether there is a tumor thrombus in the hepatic vein or portal vein. The accuracy rate of diagnosing liver cancer can reach 85%, and it can detect space-occupying lesions with a diameter of 2 cm.

3. AFp test. AFp test is a liver cancer tumor marker test. When AFp>400μg/L, pregnancy, active liver disease and gonadal embryonic tumors are excluded, and the possibility of liver cancer should be considered. If other tests such as B-ultrasound and CT still fail to find abnormalities, dynamic monitoring is required.
