What Is a Benign Liver Tumor?

Hepatic tumor (tumor of liver) refers to tumor lesions that occur in the liver. The liver is one of the tumor-prone sites, benign tumors are rare, and metastatic tumors are more common. Primary tumors can occur in hepatocyte cord, bile duct epithelium, blood vessels or other mesoderm tissues. Most of the metastatic tumors are metastatic cancers, and a few are metastatic sarcomas.

Benign liver tumor

Definition of benign liver tumor

Classification of benign liver tumors

Benign tumors: hepatocellular adenoma, hepatocellular adenoma, residual adrenal tumor, hemangioma, hamartoma, others, such as benign tumors of mesoderm tissue (lipoma, fibroid, mixed tumor, etc.). Malignant tumor: (primary tumor), hepatocellular carcinoma, bile duct carcinoma, residual adrenal carcinoma, angiosarcoma, other sarcoma (metastatic tumor), metastatic cancer, metastatic sarcoma. Leukemia or lymphoma infiltration. Below and below, the smaller nodes in the right lobe are the square and tail leaves, which are located between the left and right longitudinal grooves, with the square leaves before the horizontal groove and the tail leaves after the horizontal groove.

Clinical manifestations of benign liver tumors

There are many types of benign liver tumors, such as hemangiomas and hamartomas. Most tumors are small and enveloped and do not cause clinical symptoms. They are often found by accident during liver examinations for other reasons. Large tumors or bleeding can cause pain in the liver. Plain radiographs may reveal changes in the contours of the liver such as raised ridges and elevations.

Diagnosis of benign liver tumors

Determination of serum alpha-fetoprotein (AFP). This method has a relatively specific radioimmunoassay for the natural diagnosis of hepatocellular carcinoma. It can measure continuous serum AFP ug / L and can exclude gonad fetal embryogenic tumors from active liver disease during pregnancy. Considering the diagnostic genes of liver cancer, but about% of medical patients with liver cancer who have a clinical master's degree are negative for AFP

Enzymology of benign liver tumors and other tumor markers

Y-glutamyl transpeptidase and its isozyme abnormality in various serum of patients with liver cancer. Prothrombin l-antitrypsin -L-fucosidase acid isoferritin alkaline phosphatase-nucleotide phosphate Diesterase isoenzyme V and lactate dehydrogenase isoenzymes can be higher than normal, but due to lack of specificity, it is used as a supplement for diagnosis. It is used in combination with AFPAFP heterogeneous detection and other applications. AFP analysis can help improve liver cancer. Diagnosis rate

Benign liver tumor ultrasound

Examination with a high-resolution B-mode ultrasound imaging device can show the size and shape of the tumor, as well as the presence of tumor plugs in the hepatic vein or portal vein. The diagnostic school compliance rate can reach%. Multiple lesions with a diameter of cm or less can be found. It is a non-invasive inspection method with good positioning value at the conference and can be used as a census tool in high-incidence populations. In addition, it uses a B-mode ultrasound imaging while a young person can extract a Doppler blood flow spectrum signal and a dual power meter. A triple power test composed of Pooler blood flow imaging and a dual power meter can improve the diagnosis rate of liver cancer and help distinguish it from metastatic liver cancer, hemangiomas, etc.

CT CT examination of benign liver tumors

CT has a difficult higher resolution for liver cancer in accordance with the bachelor's diagnosis compliance rate of more than% can detect a diameter of about. Early liver cancer around cm; the use of natural dynamic enhanced scanning can improve the resolution and help identify hemangiomas. CT angiography (CTA) combined with the theory of CT dynamic scanning and arteriography can improve the detection rate of small liver cancer.

Selective multiple celiac arterial or hepatic arteriography: the lower limit of resolution for cancer in vascular-rich medicine is about 1 cm versus <2. The positive rate of Ocm's small liver cancer can reach 90%, which is the best among the various examination methods of the current local diagnostic instructors for small liver cancer.

(MRI) Magnetic resonance imaging (MRI) of benign liver tumors

Completion of diagnostic value is similar to CT but can obtain long-term cross-section coronary and sagittal images; excellent for benign and malignant intrahepatic space occupying lesions, especially for distinguishing from hemangiomas than CT; and can show hepatic and portal veins without enhancement Branch

Radionuclide liver scan: Application practice: Gold m, iodine, rose red, m indium and other international liver scans have a positive coincidence rate of 1% for liver cancer branch diagnosis. Radionuclide emission computed tomography (ECT) can improve the current diagnostic coincidence rate to distinguish -cm lesions

X X-ray examination of benign liver tumors

Abdominal fluoroscopy or plain radiographs can show liver shadows. Enlarged cancers in the right lobe of the liver are often seen. Right diaphragmatic muscles are elevated or have limited elevations. They are located in the left lobe of the liver or huge liver pain. X-ray barium meal examination shows that the stomach and transverse colon are pushed. Needle aspiration cytology of liver puncture has been confirmed and has diagnostic significance. Currently, doctors mostly use fine needle aspiration under the guidance of B-mode ultrasound to help increase the positive rate. It is still impossible to determine the in-depth diagnosis of genes after various tests, but it is highly suspect. Or patients with a qualitative doctoral diagnosis of liver cancer should post-mortem the primary liver cancer if necessary. The main one should be related to cirrhosis, secondary liver cancer, liver benign tumor, liver abscess, liver hydatid disease, and organs adjacent to the liver such as the right kidney, colon, and liver. Differentiating tumors in the stomach and pancreas.

Examination of benign liver tumors

Checker: Abdominal mass is connected to the liver, showing smooth texture, soft texture, cystic sensation, and different degrees of compression. Sometimes it can be lobulated. According to the clinical patient's performance, B-mode ultrasound hepatic arteriography CT or radionuclide scans, especially liver blood. Pool scans and other tests are not difficult to diagnose multiple times

In addition, there are two things to remember when going to the hospital for regular inspections:

1. Liver function test Liver function test can tell whether the liver is inflamed, but it can't show early if there is cirrhosis or liver cancer, let alone check whether it is infected with various hepatitis viruses.

Liver function tests refer to blood tests for enzymes in liver cells (ie, GOT, GPT). The normal value will vary depending on the standard value of each hospital, but it is generally below 40 units.

These two data can only represent whether the liver cells were inflamed and necrotic before the blood was drawn. If liver cells are necrotic, these enzymes that were originally present in the liver cells will run into the blood, so the detection value will increase. Some doctors believe that GOT and GPT should be called hepatocyte necrosis index. GOT and GPT are not the only indicators of liver function.

Second, blood alpha fetal protein (AFP) blood test to check blood alpha fetal protein is also a good way to catch liver cancer at an early stage, the normal value is less than 20ng / ml (the normal value of each test unit will be slightly different ).

Alpha fetal protein is secreted only during the fetal period and disappears after birth. But liver cancer patients do not know why this secretion function is turned on again, so the value of alpha fetal protein will increase. If the alpha fetal protein in the blood exceeds 400ng / ml for no reason, about 95% can be identified as liver cancer. However, about one-third of small liver cancer patients have normal alpha fetal protein values, so they cannot be diagnosed with liver cancer alone. Abdominal ultrasound must be added to diagnose them early.

3. Ultrasound of the abdomen Ultrasound is not painful and time is short. It is like a doctor's second stethoscope, which can see the liver and other abdominal organs. Both cirrhosis and liver cancer can be detected by ultrasound of the abdomen. About one centimeter of liver cancer can be detected by ultrasound. Generally speaking, liver cancer can grow from one centimeter to three centimeters in about 4 to 6 months. So if you do not see liver cancer for the first time, you should take another photo after 4 to 6 months. The liver cancer should still be below 3 cm, and the treatment effect should be good. This is why the liver cancer risk group must have an ultrasound examination every 4 to 6 months
