What is the best treatment for liver cancer? The most effective methods for treating lung cancer

The best treatment for liver cancer: liver transplantation

Relevant experts pointed out that liver cancer is the result of the synergistic effect of multiple factors, mainly related to hepatitis B virus, hepatitis C virus, aflatoxin, drinking water pollution, lack of certain trace elements, genetic factors, alcoholism and other factors.

According to experts, liver cancer is a highly malignant tumor. my country is a high-incidence area for liver cancer, and the incidence rate has been slowly increasing in recent years, and the mortality rate has also increased accordingly. Every year, about 200,000 patients die from advanced liver cancer.

The best treatment for liver cancer is liver transplantation

According to experts, the best way to treat liver cancer is to perform a liver transplant. Liver cancer is characterized by multiple lesions. If only local resection is performed, the recurrence rate is very high and may recur quickly. Especially for liver cancer caused by hepatitis, if liver inflammation still exists, the chance of liver cancer reappearing is still very high. Removing the patient's liver and transplanting it into a healthy liver can not only effectively cure liver cancer, but also completely cure the patient's cirrhosis and hepatitis, removing the cause and "soil" of liver cancer, which is unattainable by other treatments. Therefore, liver transplantation should be the first choice for the treatment of early liver cancer.

Experts also pointed out that the timing of surgical treatment for liver cancer patients is very important and is directly related to the long-term survival rate of patients after transplantation. Since liver transplantation is a major operation and has certain risks, many patients are unwilling to undergo liver transplantation even if liver cancer is discovered in the early stages. They would rather use other methods until there is no other way, and then they are forced to choose liver transplantation. However, at this time, the best time for liver transplantation has often been missed, and the probability of complete cure is greatly reduced. Liu Zhenwen said that in fact, the recurrence rate of advanced liver cancer after surgery is relatively high, which is not very meaningful, and liver transplantation is generally not recommended.

Liver cancer can be prevented, treated and diagnosed early

Early diagnosis of liver cancer is most important

The fear of cancer reflects people's fear of cancer. Liver cancer was once called the king of cancers. Can liver cancer be prevented? In response to the reporter's question, Professor Zheng Jiasheng clearly pointed out that liver cancer is preventable and curable. "Early diagnosis is especially important for liver cancer." Professor Zheng Jiasheng explained: Medical research shows that liver cancer is preventable.

Clinical practice has proven that hepatocellular carcinoma accounts for more than 90% of primary liver cancer in my country. Hepatocellular carcinoma is significantly different from other types of liver cancer, such as intrahepatic cholangiocarcinoma, in terms of pathogenesis, biological behavior, histological morphology, clinical manifestations, treatment methods, and prognosis. "The liver cancer we refer to in daily life mainly refers to hepatocellular carcinoma." Professor Zheng Jiasheng said that the risk factors for hepatocellular carcinoma are relatively clear in clinical practice, mainly including chronic hepatitis B virus infection, chronic hepatitis C virus infection, consumption of aflatoxin-contaminated food, drinking water contaminated by cyanobacteria toxins, and long-term alcoholism.

Clinical statistics show that more than 80% of liver cancer patients are related to hepatitis B. Blocking hepatitis B can effectively prevent liver cancer. Professor Zheng Jiasheng said that in my country, mother-to-child transmission of hepatitis B virus is an important way of hepatitis B transmission, and mother-to-child transmission blocking is an important measure to prevent newborns from developing hepatitis B. When mothers with chronic hepatitis B give birth to children, they should be vaccinated with high-titer immunoglobulin and hepatitis B vaccine in time to prevent the transmission of hepatitis B virus to their babies. my country has implemented the hepatitis B vaccination strategy since 1992, and the hepatitis B virus carrier rate has dropped from 9.09% in 2002 to 7.18% in 2007.

"At present, my country has provided free hepatitis B vaccination to children under 15 years old, and children who have not received hepatitis B vaccination should also receive a booster shot." Professor Zheng Jiasheng said that adults who have close contact with chronic hepatitis B patients may also be infected with hepatitis B, and hepatitis B vaccination is also an effective means for adults to prevent hepatitis B. Medical personnel, people who frequently come into contact with blood, staff of childcare institutions, organ transplant patients, people who frequently receive blood transfusions or blood products, people with low immune function, and people who are prone to trauma should also be vaccinated with hepatitis B vaccine to prevent hepatitis B infection. Hepatitis C mostly occurs during blood transfusion, and safe blood transfusion can effectively prevent the occurrence of hepatitis C.

Professor Zheng Jiasheng emphasized that we should remind the public: To avoid the occurrence of liver cancer, we must stop eating all kinds of moldy foods, not drink polluted water, quit smoking and limit alcohol, and maintain a healthy lifestyle, which can block other factors that induce liver cancer. We also need to remind all hepatitis patients to refrain from drinking all kinds of alcoholic beverages. All patients with chronic persistent hepatitis (chronic hepatitis B, chronic hepatitis C) should actively take antiviral treatment under the guidance of a doctor to inhibit the replication of the virus in liver cells, control the hepatitis virus at a low level, reduce liver cell damage, and thus prevent the occurrence of liver cancer. "Blocking various risk factors for liver cancer can effectively prevent liver cancer." Professor Zheng Jiasheng said.

Liver cancer can be detected early

It is now known to the public that the treatment effects of liver cancer are very different when it is detected early or late. When some patients are diagnosed with liver cancer clinically, most of them have been diagnosed in the middle or late stages. Can liver cancer be detected very early?

Professor Zheng Jiasheng clearly stated that liver cancer can be detected early. However, he wanted to point out that most of the liver cancer patients currently found in clinical practice are indeed in the middle and late stages.

"The liver is the largest organ in the human body and is also a substantial organ." Professor Zheng Jiasheng said that because there is no nerve distribution in the liver and lacks sensory function, the tumor is small in the early stage of liver cancer, and patients usually do not feel any discomfort. It is not until the tumor gradually grows and pulls on the liver capsule or even erodes the surrounding tissues that patients feel pain, accompanied by vomiting, abdominal distension, weight loss, fatigue, jaundice and other symptoms before seeking medical treatment. At this time, liver cancer has reached the middle and late stages. Clinically, it has been found that most patients still have no typical symptoms when the liver tumor reaches 3-5 cm. The clinical symptoms of liver cancer are non-specific and may be caused by a variety of diseases. It is not easy to associate liver cancer with symptoms alone. Inexperienced doctors are very likely to misdiagnose or miss the diagnosis.

Professor Zheng Jiasheng believes that the early detection of liver cancer cannot rely solely on the examination of patients during outpatient medical treatment. Popularizing liver cancer screening for high-risk groups can detect early liver cancer. "Most liver cancers occur in patients with hepatitis B and hepatitis C. We call them the high-risk group for liver cancer." Professor Zheng Jiasheng pointed out that serum alpha-fetoprotein testing and liver ultrasound examination are important means to detect early liver cancer. Alpha-fetoprotein is an important marker for liver cancer. An increase in its index indicates that the patient may have liver cancer. CT and ultrasound examinations can detect tumors with a diameter of more than 0.5 cm.

Professor Zheng Jiasheng reminded that patients with chronic hepatitis B and C should undergo alpha-fetoprotein screening and ultrasound examination every six months. The screening interval for patients with liver cirrhosis should be shortened to once every three months.

Regular screening is the guarantee for early detection of liver cancer

People often say that having liver cancer is equivalent to being sentenced to death. Does the medical community currently have any effective treatments for liver cancer?

In this regard, Professor Zheng Jiasheng emphasized that with the development of science and technology, liver cancer is no longer an incurable disease. There are currently many methods for the clinical treatment of liver cancer. Surgical resection and liver transplantation of early liver cancer are the most effective traditional clinical treatment methods. For patients with liver cancer with a diameter less than 2 cm, the 5-year survival rate after tumor surgical resection is 90%; for patients with a diameter less than 3 cm and less than 3 tumors, the 5-year survival rate after tumor surgical resection is also 40-70%. Professor Zheng Jiasheng particularly pointed out that minimally invasive ablation treatment technology has become an important means of treating liver cancer.

"In the past decade, various minimally invasive ablation technologies for liver cancer treatment have made significant progress in my country." Professor Zheng Jiasheng said proudly that clinicians use imaging equipment to guide minimally invasive surgical instruments, and can directly reach the tumor lesions through percutaneous puncture or perforation. Under real-time image monitoring, radiofrequency ablation, microwave ablation, laser ablation, cryoablation and other minimally invasive surgeries are performed on the tumor to remove the tumor at a specific point, changing the traditional open abdominal surgery model. Minimally invasive surgery for cancer treatment applies tumor inspection, treatment, monitoring, and evaluation to the surgical process. Surgery is performed under imaging monitoring, and the tumor treatment situation can be immediately evaluated during the operation. Minimally invasive surgery for liver cancer treatment has accurate positioning, small trauma, few complications, and a wide range of applications. It has a slight impact on the patient's body, can protect the function of human organs to the greatest extent, and the patient recovers quickly after surgery.

Professor Zheng Jiasheng revealed that clinical treatment results show that early-stage liver cancer patients who are not suitable for or unwilling to undergo traditional surgical resection and more than 60% of patients with advanced liver cancer can undergo minimally invasive ablation to remove liver tumors, achieve tumor-free survival, and improve their quality of life. my country's minimally invasive ablation treatment for liver cancer has reached the international leading level.
