Liver cancer intervention combined with "cocktail therapy" can significantly prolong the survival time of advanced patients

Release time:Jun 25, 2024 14:12 PM

Liver cancer has an insidious onset, and only about 20% of patients can receive surgical resection when clinically discovered. Professor Xia Jinglin's team from the Department of Liver Oncology at Zhongshan Hospital Affiliated to Fudan University proposed a "cocktail therapy" for liver cancer, and recently published a research paper titled "Immunochemotherapy synergistically targeting the SAMD4B-APOA2-PD-L1 axis to enhance anti-tumor immunity in hepatocellular carcinoma" in the journal Cell Death and Disease on the effects of cocktail therapy against liver cancer and its mechanism of action.

It is reported that drug treatments for liver cancer include hepatic artery infusion chemotherapy, targeted therapy, immunotherapy, targeted combined immunotherapy, dual immunotherapy, etc. These methods can prolong the survival time of patients with advanced liver cancer to a certain extent, but the effects are not generally ideal, and there are many side effects, high costs, and inconvenient treatment. The clinical application effect of interventional combined targeted immunotherapy has not yet met expectations. For a long time, exploring safe, effective, economical, and convenient comprehensive treatment plans has been an urgent problem to be solved in the diagnosis and treatment of liver cancer.

The concept of cocktail therapy originated from AIDS treatment. Its principle is to combine drugs with different mechanisms of action to achieve the best therapeutic effect. The drugs in the cocktail therapy for liver cancer are all common drugs that are cheap, have few toxic side effects, and are easy to use.

Professor Xia Jinglin's team has found in more than a decade of clinical practice that intervention combined with cocktail drugs can significantly prolong the survival of advanced liver cancer compared with intervention alone. The one-, two-, and three-year survival rates of the combined cocktail drug group were significantly higher than those of the intervention alone group, at 88.1%, 61.6%, 41.0% and 53.5%, 26.8%, 23.9%, respectively. In addition, cocktail therapy has reduced the cost of treatment for patients to a certain extent, alleviating their financial pressure.

To further reveal the mechanism of action of cocktail therapy for liver cancer, the team conducted research in vivo and in vitro and at the molecular level and found that compared with a single drug or a combination of two drugs, the three-drug cocktail combination can relieve the immunosuppression caused by liver cancer by regulating the SAMD4B-APOA2-PD-L1 axis. In other words, the cocktail drug can reactivate the human immune system to eliminate liver cancer cells.

The review experts fully affirmed the team's research: this study discovered and proposed for the first time the synergistic effect of immunochemotherapy in liver cancer cocktails, which can bring new hope to patients with advanced liver cancer who have lost the opportunity for surgical resection, and has scientific and social value.

Xia Jinglin explained that the liver cancer cocktail therapy is also called the thalidomide-based liver cancer cocktail therapy, which mainly includes three common drugs: thalidomide, carmofur, and compound blister beetle.

Thalidomide was used to stop vomiting during pregnancy in the 1960s. The drug can cause fetuses to have short limbs and be called "seal babies" because it can inhibit fetal vascular development. Because thalidomide has anti-angiogenic effects, it can be used to inhibit tumor angiogenesis and treat tumors. Later studies also found that thalidomide has an immunomodulatory effect, which is equivalent to the dual effects of targeted and immunotherapy. Carmofur is often used for digestive tract tumors; compound blister beetles are Chinese patent medicines for liver cancer.

Experts say that the triple cocktail drugs have different mechanisms of action and can play the role of 111>3. In addition, the side effects of the drugs can offset each other, complement each other's strengths and improve safety. Only a small dose can play a "four ounces to move a thousand pounds" role, and the convenience of oral administration is also more conducive to improving patient compliance and achieving longer survival.

What changes will it bring? Analysis | The first "Regulations" integrating patriotic hygiene and health promotion are written into law

The "Shanghai Patriotic Hygiene and Health Promotion Regulations" were reviewed and approved by the Standing Committee of the Municipal People's Congress and will be officially implemented on November 1 this year. This is also the first regulation in my country that integrates patriotic hygiene and health promotion. The "Regulations" achieve the transformation of patriotic health from environmental health management to comprehensive social health management through three major highlights: "emphasis on social health co-governance, promoting urban health co-construction, and advocating health sharing for all". What does it mean for the "Regulations" to be enacted into law? What significance does the "Regulations" have for urban development and personal health? Jiefang Daily·Shangguan News reporter interviewed industry experts on this. Innovative integration of health care and health promotion to implement the "Regulations" is Shanghai's improvement of the "big health and big health" pattern and the promotion of patriotic health's transformation from environmental health management to comprehensive social health management.

Recently, the "Skin Health Innovation Class" jointly organized by the Shanghai Health Promotion Center and Shanghai Daily entered the private Zhengda Foreign Language School in Pudong New Area. According to the news, the incidence of atopic dermatitis has been continuously increasing in the past decade, with a prevalence rate of 12.94% in children aged 1-7 and 30.48% in infants under 1 year old. According to the 2022 Survey on Adolescent Skin Health, over half of teenagers have suffered from skin related diseases, and nearly 60% of patients are still unable to sleep due to itching, which has irreversible effects on their learning, life, physical and mental development, and healthy growth. Atopic dermatitis, also known as atopic dermatitis, is a chronic, recurrent, inflammatory, and itchy skin disease related to genetic hypersensitivity. Most patients develop from recurrent episodes of infantile eczema,

"Doctors sometimes act like detectives, uncovering the cocoons, dispelling the fog of illness, and identifying the root cause of patients. At this time, perceptible brain pacemakers are like smart assistants, playing a therapeutic role while also capturing specific EEG signals related to disease symptoms in the patient's brain. It should be noted that achieving this in a complex brain network is as difficult as hearing whispers under the roar of airplanes. The continuous progress of technology can provide patients with more accurate and personalized treatment, and we also look forward to the day when diseases can be overcome."

Due to the appearance of a huge coronary artery aneurysm and occlusion after suffering from Kawasaki disease, two children went to the National Children's Medical Center Fudan University Affiliated Pediatric Hospital for treatment. A multidisciplinary team developed an individualized coronary artery bypass surgery plan for them. In the end, the two children underwent surgery on the same day and were reborn. They recovered and were discharged smoothly recently. 9-year-old Heihei and 5-year-old Ana sought medical attention due to chest pain, palpitations, post activity fatigue, and decreased activity. They were diagnosed with Kawasaki disease, giant coronary artery aneurysm, coronary artery occlusion, and myocardial ischemia. They sought medical attention from multiple hospitals across the country but were unsuccessful. Parents came to Fudan University Affiliated Pediatric Hospital with their last hope for treatment. Professor Liu Fang, the director of the cardiology department, received the patient and carefully reviewed the relevant examination materials before telling the parents, "Please rest assured that we can treat it!"
