What exactly is cancer immunotherapy? Does it really help in the diagnosis and treatment of cancer?

Each patient's actual situation is different, and each hospital's and each doctor's medication experience may also be different. If you don't have enough expertise, follow the advice of a doctor at a regular hospital. Don't just look at the Internet and other people's information, and don't question the decisions of clinical hospitals and doctors with the information introduced in the text and for popular science purposes.

Immunity**. At present, it is the fifth largest cancer after surgery, chemotherapy, radiotherapy, and targeting.

There are more than 10 kinds of immune checkpoint inhibitor related drugs on the market in China, covering common carcinogens such as melanoma, lung cancer, breast cancer, esophageal cancer, etc., and more and more people in some cancer patients know how to immune**, and it has also become a common clinical choice in some types of tumors**. However, this new approach confuses a lot of people, and tumor immunity is a newer approach to cancer.

It mainly selects immune cells provided by the patient or his relatives to mobilize the body's immune function, kill cancer cells, restore the body's normal immune system, and balance the growth of cancer cells. Combination is recommended for cancer patients**. The immune system can not only resist the invasion of microorganisms, but also remove the host component of intramuscular changes, and the body has an anti-tumor immune mechanism.

When the immune monitoring function is impaired by the immune system itself or by tumor cells, providing favorable conditions for the occurrence of tumors, biological** or chemotherapy alone may not be effective, but in order to improve the survival rate of patients, the method must be adjusted in time according to the patient's condition**. The target of immunity is normal immune cells, and the goal is to activate the body's own immune system** cancer.

The effect of some cancer immunity is better than that of traditional cancer, and it has certain advantages, and promoting the deep docking of tumor immunity and precision medicine is an important measure to improve China's tumor technology and promote the realization of national health, and it may take about 2-3 years before and after high-risk lymphoma, the first 6 courses of chemotherapy, and then 6 courses of treatment, which will take about 1 year, and then transplantation, which may also take 2 years after transplantation.

This ** method is actually true, and it is also helpful for the diagnosis and treatment of cancer, because it can prevent the spread of cancer cells and increase immune cells, but if the cancer is advanced, it basically can't**.

I think cancer immunity is a very important approach that has been widely used at present; It is helpful in the diagnosis and treatment of cancer, and it can destroy cancer cells, but it does not damage the body.

Cancer is currently one of the leading causes of human death. According to the Global Cancer Report 2014, new cancer cases and deaths continue to rise globally, with nearly half of the new cases occurring in Asia, most of them in China.

The main forms of cancer are surgery, radiotherapy and chemotherapy, but with the progress of medical science, immunology, targeting, intervention, radiofrequency and other methods continue to emerge, providing new ways for cancer patients. As an innovative approach, tumor immunity has become a hot topic in the field of tumor research.

The design idea of "cancer immunity**" is to remove tumor cells from the body by strengthening the body's own immune system. At present, cancer immunity** is divided into four main categories: adoptive cells**, immune checkpoint blockers, non-specific immune activators, and cancer vaccines.

This year's award is for immune checkpoint blockade**. What is the "working process" of immunity**? New forms of immunity** are brought about by immune checkpoint inhibitors and recombinant CAR-T cells**.

Immune checkpoint inhibitors do not directly target cancer cells, but allow the body's immune system to kill cancer cells by removing the immune system's restrictions (PD-1 inhibitors) or by removing the cancer cells' defense system (PD-L1 inhibitors). Immune cells (T cells) act like patrols, looking for bad actors in the body to eliminate them. But in order to prevent them from abusing the police, the body will also put some restrictions on immune cells.

When the T cells screen the cells, they use a cell surface protein called PD-1 to test like a baton. If the other party is a good citizen with thick eyebrows and big eyes, they will respond by handing over their ID card, that is, PD-L1, a transmembrane protein on the cell surface; As soon as the two proteins shake hands, the T cells will say, "It's okay to go you." But if the other party doesn't have PD-L1 and just says "please don't fight", the T cells will be beaten to the point that they are completely skinned.

This is one of the mechanisms by which T cells identify invaders and bad actors.

The problem is that many cancer cells can express PD-L1 and get away with it when T cells are examined. The T cells saw that although the cancer cells were roe deer, the documents were complete and abundant (who would show the police 30 ID cards at the same time), and they had to let them go in confusion.

Antibody drugs such as PD-1 inhibitors use antibodies that can bind to PD-1 and add a cover to the baton in advance, so that T cells are no longer confused by the 30 copies of PD-L1 of cancer cells, so as to let go of their hands and kill cancer cells. These immune checkpoint inhibitor drugs no longer need to first identify the driver gene of the cancer cells (it is sometimes difficult to determine the underlying driver gene), as long as they express PD-L1, then they have the potential to activate the immune system to kill them.

Immunity** is mainly the use of the body's own immune system to attack tumors.

Immuno**can** advanced cancer that has metastasized extensively. Patients with advanced cancer who failed all the criteria** still achieved good results after using immunization**.

It is a class of methods that use the body's own immune system** for disease. Tumor immunity is naturally a type of tumor immunity.

Huang Po sells melons and boasts of herself. It's all fake, and when you encounter it, it's recommended to call the police directly or complain to the local medical department.

1. If it is true, can such a major human invention not be on TV? News? How many days can a radio station not follow up on the story?

2. At present, human science and technology are still being studied, and it is still a topic that scientists have not yet decided. It is not even known whether "cancer cells" exist or not. What do you mean by "cancer cell immunity"?

3. Regarding "cancer immunity", at present, human science and technology only discovers more than 240 viruses that are easy to cause human cancer, and only 2-24 of them are researched and immunologically studied. There are thousands of viruses that are not meant to cause (but can cause) cancer in humans, and there is no research yet! Now the lie here is indeed "boundless", and he actually "became a god" overnight, what poison can be dealt with!

Immunity** is the use of immune mechanisms in the body to fight tumor cells.

Although the situation in the advanced stage is not optimistic, it is relatively stable and safe for radical methods such as surgery, chemotherapy and radiotherapy.

It is important to know that all cancer cells in the normal human body, the reason why they do not spread and do not deteriorate and do not have adverse effects on the human body is that normal people's immunity and self-regulation ability are normal, so immunity ** improves the overall immunity, relatively speaking, the deterioration and spread of cancer cells are curbed to a certain extent, prolonging life and improving the overall ability indicators of the body.

In terms of effect, it depends on what method of immunity you use, and it must be obvious if you use it correctly.

Epidemics are the use of immune mechanisms in the body to fight tumor cells.

If it is an advanced stage of stomach cancer, then consider it. There are many symptoms. This may cause loss of appetite, nausea, vomiting today.

In advanced stages, cancer cells may spread. This can lead to widespread body aches. Then there are more clinical symptoms.

It is recommended that you have NK immune cells**.

1. The use of PD-1 inhibitors or PD-L1 inhibitors is a precise category**, so the medication is very targeted.

There are two main PD-1 inhibitors on the market: Keytruda and Opdivo. Mainly non-small cell tumors, such as kidney cancer, melanoma, non-small cell lung cancer, etc. (the specific needs to be determined by the ** plan after the doctor's diagnosis).

There is another PD-1 inhibitor which is Tekentriq, which has a significant effect on bladder cancer.

2. Immunity** mainly uses the body's own immune system to attack tumors. Scientists have found that although most tumors can trigger a response from the immune system, some tumors can evade detection by the immune system and spread in patients with normal immune function. The key to this is the PD-L1 protein on cancer cells, which binds to the PD-1 receptor of immune cells, so that immune cells cannot function normally.

3. If you can prevent cancer cells from shaking hands with immune cells, then you can restart the immune cells and let the immune cells work normally. Immunity** is the use of PD-1 inhibitors to unravel the camouflage of tumor cells, allowing their own immune cells to kill cancer cells.
