Can immune therapy use immune cells to fight cancer cells?

Data show that 6 people are diagnosed with cancer every minute in the country, and in real life, many people feel that more and more people have cancer around them. Please pay attention-can cell immunotherapy overcome cancer?

At the beginning of 2013, the National Cancer Registration Center released the "2012 China Cancer Registration Annual Report", showing that there are about 3.12 million new cancer cases each year and 2.7 million deaths from cancer each year. Six people are diagnosed with cancer every minute across the country, and in real life, many people feel that more and more people are suffering from cancer around them, and news of cancer patients appears in the media and social networks from time to time.

The hidden period of cancer can last for decades

In general, the incidence of cancer increases with age. With the exception of a few hematological tumors (such as certain leukemias) and malignant sarcomas derived from mesenchymal tissue (such as osteosarcoma), young people rarely develop cancer. In people over 60 years old, the highest incidence of cancer can reach 2.5%. Smoking, infection with viruses, exposure to chemical carcinogens, or radiation can increase the risk of cancer; regional, ethnic, and family genetic differences are also related to cancer prevalence. Therefore, the factors that affect the incidence of cancer can be roughly summarized into two aspects: environment and genetics, and each type of cancer has its own focus.

Cancer cells develop from a "treason" cell. After a long period of development and growth, when the number of cancerous cells reaches 109, the weight of tumor tissue is only about 1 gram. It can be seen that the development of cancer is a long-term process. When cancer tissue is still in a single cell stage or is very small, medical methods cannot be found. Therefore, the development process of a cancerous lesion visible to the naked eye may have passed for years or even decades.

This is why many cancer patients have to assist with other treatments after surgical removal of the lesion: although the original lesion has been removed, it is difficult to rule out that cancer cells have spread through the blood or other routes before the surgery. The purpose of chemotherapy is to use drugs to kill certain hyperplastic cells throughout the body (active hyperplasia is often a characteristic of cancer cells) to achieve the purpose of treating cancer. Of course, this kind of killing will often damage normal cells in the body, so the drawbacks of traditional cancer treatment have prompted scientists to find a new treatment.

Cellular immunotherapy prevents relapse

Zhang Xinjiang, a 48-year-old Jiangxi, is a manager of a grassroots passenger transportation company. In 2008, he began to lose weight inexplicably, lost more than 20 pounds in more than ten days, and felt that his body was not as good as before. His family persuaded him to go to the hospital for a medical examination. Zhang Xinjiang believed that it was only caused by the busy work recently, and it would be fine after this busy time, not realizing the seriousness of the problem. But his friend's statement that something is wrong must wake up Zhang Xinjiang. He hurried to the hospital to do a detailed examination-a tumor was found in the left kidney. Double kidney enhanced CT showed a huge mass in the left kidney, which was normal The boundaries of renal tissue are unclear, consider left kidney cancer.

It turned out that Zhang Xinjiang's overthrow was that cancer cells were consuming a lot of nutrients in his body. Zhang Xinjiang learned from the news that the Chinese-American doctor successfully passed the immune cells in the cancer patient's body to fully restore the patient's health, and the disease did not recur within two years. He found 307 hospitals in China who are developing this technology.

The CTC Tumor Biotherapy Center of the 307 Hospital of the Chinese People's Liberation Army is affiliated to the Army's Hematopoietic Stem Cell Research Institute, and has accumulated rich clinical and basic research experience in the field of tumor biotherapy. Zhang Xinjiang told reporters that through the cell immunotherapy implemented by the 307 Hospital-using immune cells to fight cancer cells, a method of cancer treatment has been achieved. The cancer has not relapsed for two years, and life and work have returned to normal.

Cellular immunotherapy has exceeded expectations

In China, the CTC Cancer Biotherapy Center of the 307 Hospital of the People's Liberation Army took the lead in successfully applying cellular immunotherapy to clinical treatment. After several years of clinical research, it has been confirmed that the actual efficacy of cellular immunotherapy has exceeded the expectations of researchers. Compared with radiotherapy and chemotherapy, it has obvious advantages: first, it can effectively remove residual cancer cells and small lesions after surgery, radiotherapy and chemotherapy, effectively prevent tumor recurrence and metastasis; second, it can enhance the sensitivity of radiotherapy and reduce the side effects of radiotherapy, Enhance the sensitivity to chemical drugs and improve the efficacy of chemotherapy; Third, because tumor biotherapy has immunomodulatory and somatic repair effects, while treating tumors, it can alleviate the discomfort and mental state of most patients, especially after radiotherapy and chemotherapy There is also a significant recovery of physical strength, which greatly improves the quality of life of cancer patients; Fourth, for patients with advanced tumors who have lost the opportunity for surgery or cancer cells have recurred or metastasized, they can quickly relieve their clinical symptoms and relieve patients' pain; they are ineffective for radiotherapy and chemotherapy And patients who are resistant to chemotherapy drugs The same treatment can be used to extend the biological survival, improve quality of life.

Experts from the CTC Cancer Biotherapy Center of the 307 Hospital of the People's Liberation Army pointed out that the occurrence and development of cancer are closely related to the body's immune function. The reason why patients relapse repeatedly is because the cancer cells remaining in the body during treatment continue to do evil. The method removes most of the cancer mass, and the removal of these remaining tiny cancer cells is the root cause of tumor recurrence. At this time, it is the best time to select cellular immunotherapy and use immunocompetent cells to directly kill the cancer cells. It can also be said that Zhang Xinjiang is the beneficiary of individualized comprehensive treatment of cancer.

Individualized comprehensive treatment is based on the patient's body condition, tumor pathology type, clinical stage and development trend, etc., using scientific, reasonable and planned methods of existing surgery, radiotherapy, chemotherapy, biological treatment, etc., with a view to maximizing the increase in tumor patients Cure rate, prolong survival time and improve patient's quality of life.

At present, the center has confirmed through a large number of clinical cases that cell immunotherapy is effective for all solid tumors and malignant blood diseases, and the cancer disease control rate can reach 70%, and the effective rate for some cancers can reach more than 40%, especially for Kidney cancer, soft tissue sarcoma, melanoma, leukemia, prostate cancer, and lung cancer are effective. Individualized comprehensive treatment of tumors has gradually become a new option for the treatment of solid tumors and hematological tumors.
