    a "sky-high" vaccine to prevent 12 types of cancer, which is said to be quietly spreading among wealthy people.
    media recently reported that the
    MDX Medical Group released the "DCV Cancer Vaccine", 98,000 yuan injection, can prevent more than 12 types of cancer, including prostate cancer, breast cancer, lung cancer.
    there's such a good thing? Science and Technology Daily reporter immediately connected with the China Anti-Cancer Association science and technology propaganda minister, the capital medical university Xuanwu Hospital professor, to listen to what he said."What cancer can be cured?" From this advertising term, it can basically be judged to be pseudoscience. "To say nothing else, in terms of lung cancer alone, there is small cell lung cancer and non-small cell lung cancer, non-small cell lung cancer also includes squamous, adenocarcinoma, squamous cancer and large cell carcinoma; Preventing lung cancer alone is unlikely, let alone preventing 12 types of cancer together.
    characteristics of malignant tumors are academically known as "heterogeneity" and can be roughly understood as being completely different even if they are classified as the same tumor. Academic papers have shown that heterogeneity is divided into two types: one is at different times when the tumor occurs, the same patient's tumor cells have different genetic mutations, and the other is that different patients have the same tumor, but that "same" may not be the same, only the same esoteric, does not represent the same genotype.
    ,
    ,000-year-old Chinese president, previously used a very graphic example to explain "heterogeneity" at an academic seminar. He said: The human genome is like taking a disk, falling underground, throwing a million times without two fragments is the same, no two tumor patients mutation is the same. The human body has 3 billion base pairs, changing tens of millions of may not cause tumors. The main question in treating tumors is to find out which one is driving the mutation before it is possible to target treatment. Scientists are now using big data to find the most critical drivers of mutations, which can be understood as core components, and thousands of tumor-driven genes are being found based on clinical data and proportions.
    it is now impossible to control the broad-spectrum WT1 gene (assuming that the substance injected can regulate the gene) as mentioned in the "DCV Cancer Vaccine" product description alone, and the so-called "one-of-a-world gene" is simply a nihility.
    therefore, "all-encompassing, all-encompassing disease" is the first side of the "mirror", especially for the occurrence of complex malignant tumors, it is not possible to "one enemy ten".
    " also has a characteristic, there is no specific research institutions and research events. If it's true, there should be specific scientific research projects and data on scientific research, and results should be presented at international or national cancer conferences. "If it is clear that the work of a research institute or team of scientific research at a university in the United States has been carried out, and a series of experimental studies have been conducted, then other teams of scientists should be able to validate the study or present their findings and data at the Global Oncology Congress ASCO or the CSCO Conference of the National Oncology Conference."
    and
    MDX Medical Group released the DCV Cancer Vaccine without disclosing any clinical trial data, how the relevant clinical validation is advanced, how effective the Phase III clinical study is, whether there are relevant papers published in academic journals, and which scientists and research teams are involved in the research. To be clear, this result is like being produced out of no space and cannot be traced back.
    "out of the sky, can not be traced back" is the second side of the "mirror", "commercial manipulation, speculation" is the third side of the "mirror mirror."
    " the production of a fake news, although empty, but there must be a huge economic interest driven. "The research and innovation of new anti-tumor drugs requires a lot of money, especially in the clinical validation phase, which will require hundreds of millions of dollars, " he said.
    At this time, the concept of speculation, raising the stock price, capital and other methods have become a lot of capital players, and fake news has become one of the springboards for them to "play around" the capital market. Sales performance and followers, as long as the head, this wave of operations may attract investment, business manipulation of the so-called "model." As the media have analyzed, its commercial essence is to cut vegetables.this is a lie about the tumor vaccine, but the "tumor vaccine" is a true new biotechnology in recent years.
    are familiar to people include: cervical cancer vaccine, hepatitis B vaccine and so on.
    principle, the principle of preventive tumor vaccine is to prevent microbial infection induced tumors. For example, cervical cancer vaccine is to prevent polybromavirus, hepatitis B vaccine is to prevent liver cancer, prevention of EB virus, prevention of nasopharyngeal cancer, prevention of Helicobacter pylhoid, prevention of stomach cancer. Li Zhongming, editor-in-chief of Contemporary New Vaccines (first edition), who has worked on the FDA's review, explained to Science and Technology Daily that the current vaccine against cancer must be related to microorganisms, and only therapeutic vaccines are targeted at tumors.
    the point! The tumor vaccine is divided into preventive and therapeutic, injected into healthy people and tumor patients respectively.
    vaccine only targets tumors caused by microorganisms such as viruses, and because it can clarify the mechanism of tumor formation, it can be prevented, and a variety of vaccines are already available.
    therapeutic tumor vaccine, a cancer vaccine for prostate cancer is now available in the United States, and several therapeutic products are in clinical trials.
    the therapeutic tumor vaccine, since it is aimed at tumor patients, is therapeutic, why is it also called a vaccine?
    , founder and CEO of S Microbiology, a leading cancer vaccine company in China, explained to Science and Technology Daily, "The tumor vaccine is actually a kind of immunotherapy." For example, we use mRNA to express tumor antigens, which act like a marker (wearing a red hat) that alerts and mobilizes the police (immune system) to catch a thief, and the person wearing a red hat is a thief. The immune system can then locate the thief in a red hat and attack the tumor. This
    immunotherapy is also known as the "tumor vaccine" because "portraits" make the immune system aware that tumors work in the same way as vaccines.
    " this is different from chemical drugs, antibody drugs to introduce foreign aid to combat the force of the method. Tumor vaccines rely entirely on the body's own immune response to eliminate tumors. Li said that once the immunotherapy is effective, generally will not produce resistance, the immune system will "intelligently follow up" until the tumor hit the "lost armor." In addition, immunotherapy produces immune memory, and when the body again encounters the same pathogen attack, it quickly produces an immune response to eliminate the pathogen. And with traditional methods, it is easy to produce drug resistance, tumors will "run away", if relapsed, may be more dangerous.
