What does interventional treatment for liver cancer specifically refer to? 7 types of liver cancer patients are suitable for interventional treatment

Interventional treatment of liver cancer is a method of diagnosis and treatment that involves inserting a special puncture needle or catheter into the tumor area of ​​the liver under the guidance of X-ray television, CT, or B-ultrasound. With much clinical experience, it has developed rapidly and has become an effective means of treating liver cancer.

The following liver cancer patients can undergo liver cancer interventional treatment:

(1) Primary or metastatic liver cancer that is considered unresectable for various reasons, or small liver cancer that the patient is unwilling to undergo surgery for.

(2) As a preparation before surgery, interventional therapy can shrink liver cancer and make it easier to remove. In addition, intervention can reduce the spread and recurrence of the tumor.

(3) Patients with incomplete liver cancer resection, postoperative recurrence, or failure of other treatment methods.

(4) Liver cancer lesions do not rupture and bleed

(5) No serious damage to liver and kidney function.

(6) Patients without severe jaundice and ascites.

(7) The patient is in good general condition and has no serious hemorrhagic diseases.

Due to the advancement of science and technology, the catheters, guidewires, and puncture needles used for intervention have been greatly improved. In addition, people have more research and knowledge about liver cancer, so there are more treatment methods, such as hepatic artery catheter chemotherapy, thermal chemotherapy, hepatic artery catheter embolization, thermal embolism, percutaneous puncture anhydrous alcohol injection, percutaneous puncture iodized oil plus chemotherapy drug injection, and liver cancer isotope-guided therapy.

The effectiveness of interventional therapy is determined by the blood supply characteristics of liver cancer. Under normal circumstances, the liver is supplied by the hepatic artery and portal vein, of which the portal vein accounts for 75% to 80% and the hepatic artery accounts for 20% to 25%. The blood supply of liver cancer is just the opposite. More than 90% to 95% of liver cancer is supplied by the hepatic artery, and the portal vein supplies very little. This makes treatment convenient. Through the hepatic artery catheterization, drugs can directly enter the liver cancer tissue, increase the local drug concentration, and kill cancer cells. In addition, some embolic substances such as iodized oil and gelatin sponge are used to block the blood supply artery of liver cancer, cut off its nutrition, and the tumor tissue will necrotize, thereby achieving the purpose of treatment.

Observation and care of patients after interventional surgery is an important link. After surgery, the patient's lower limb on the punctured side should be immobilized for 24 hours, and food and drink can be prohibited for 6 to 12 hours for easy observation; closely observe changes in the patient's breathing, blood pressure, pulse, etc.; whether there is bleeding from the incision; pay attention to the amount and color of urine; postoperative fluid replacement and antibiotics to prevent infection for 3 to 5 days. Due to chemotherapy embolization, patients may experience nausea, vomiting, abdominal pain, fever, etc., which should be treated symptomatically in time, and they will improve after 1 week. After surgery, patients should review liver function, kidney function, blood routine, etc., and pay attention to changes in various indicators, and actively deal with problems when they are found.

Although liver cancer is currently treated mainly by surgery and intervention, comprehensive treatment is more important. For example, interventional chemotherapy after liver cancer surgery can not only detect residual lesions, but also prevent postoperative recurrence and metastasis. Liver cancer can shrink tumors through interventional treatment to obtain the opportunity for resection. In addition, interventional treatment combined with radiotherapy, X-knife, gamma knife, HIFU knife, computer-guided multi-electrode radiofrequency, etc. also plays a huge role in the treatment of liver cancer. Interventional treatment of liver cancer with thermal therapy, electrochemical therapy, and isotope-guided therapy are also under research. The efficacy of interventional treatment of liver cancer plus immunotherapy and traditional Chinese medicine treatment has also been confirmed. In short, liver cancer is a comprehensive treatment mainly based on surgery and intervention. Therefore, patients with liver cancer should have confidence. If conditions permit, it is best to go to a cancer hospital or a comprehensive hospital oncology department for examination, diagnosis and treatment to achieve the best treatment effect.
