Causes of cancer recurrence and new trends in cancer treatment! We know that there are two major problems in the treatment of cancer, one is the metastasis of cancer, and the other is the recurrence of cancer. In the past many of these two major therapeutic problems have been key factors restricting the cure of cancer. With the deepening of human understanding of molecular cells and the immune system, human beings have a better understanding of cancer diseases.

Overview

Comprehensive observation from various aspects such as etiology, pathology, genetics, development, cellular properties, and response to treatment. Cancer phenomenon is different from any human disease currently existing. It is difficult to imagine that cancer can achieve satisfactory results. Research and practice over the years have fully proved this. Traditionally known cancers are abnormal growths with clear pathophysiological boundaries: cancer cells are a group of cells that lose growth control and have abnormal biological behaviors; cancers are not regulated by the body's normal growth regulation mechanism, and grow out of control and destroy normal tissue And organs; heterogeneity, invasion, and metastasis are its basic characteristics; the causes of cancer are complex and diverse, including human genetic factors, local microenvironmental factors and immunological factors, as well as external biological, physical and chemical induction and Mutagenic factors.

Due to the genetic factors inherent in the occurrence of cancer in the human body and the molecular genetic basis of gene mutations, it is easy to blame the root cause of cancer on the existence of oncogenes and gene mutations. This traditional understanding more reflects people's appearance of cancer. The strategies that people rely on to overcome cancer also pay more attention to the control of the cause of cancer and the killing of cancer. The results are often idealized and superficial. , One-sided characteristics. Cancer research and clinical treatment for more than a century have been based on such a theory. It is conceivable that it is impossible to achieve a real breakthrough in cancer treatment. The understanding of the origin of cancer stem cells makes the cancer phenomenon with more complex biological properties, indicating that the cancer phenomenon is different from any other human diseases that have existed to date. To some extent, the cancer phenomenon has certain functions with the normal human hematopoietic function. In a similar way, this new understanding of the cancer phenomenon not only challenges traditional cancer awareness, but will also require a review of traditional cancer treatment concepts.

The understanding of the cancer tradition has led people to treat cancer as a "bad person" with clear boundaries in the process of cancer treatment, trying to completely eliminate it through traditional treatment methods. This traditional treatment philosophy reflects the lack of understanding of the nature of cancer, often resulting in irrational treatment or even overtreatment, which not only does not solve the cancer problem, but also artificially exacerbates cancer progression. Cancer treatment still needs to follow the principle of "comprehensive treatment, individualized plan", but currently still attaches importance to surgery, radiotherapy and chemotherapy, bio-targeted therapy, etc., and ignores the power of cancer patients to resist cancer through biological immunotherapy and other adjuvant treatment Construction and maintenance, did not achieve true comprehensive treatment and individualized treatment. It can be said that cancer

(1) Cancer is an immunological disease

The presence of oncogenes and gene mutations are the prerequisites and foundations for cancer to occur, and the "weakness" of the immune system's surveillance function may be the direct cause of cancer--is cancer an immunological disease? In the human immune system, cellular immunity is the main component of cancer immunity. Cellular immunity consists of innate immunity and acquired immunity. The traditional concept of innate immunity is gradually established and passed on to the offspring by the body in the long-term germline development and evolution process. This kind of immunity is characterized by a wide range of effects, can fight a variety of microorganisms, has no specificity or specificity, so it is also called non-specific immunity. For example, phagocytes have the ability to phagocytose and clear various microorganisms. Another characteristic of innate immunity is that it is controlled by genetic genes, so it is also called species immunity. This immune effect comes quickly and is relatively stable. If the number of invading microorganisms is large or the toxicity is high, it may not be able to resist it.

The immune surveillance function that causes cancerous cells to "escape" may be caused by two reasons: On the one hand, the cause is derived from cancer cells. The other cause is the immune system. Due to genetic factors, the cellular immune surveillance function is weak. This weakness of immune surveillance capability is not a typical pathological phenomenon, but just a difference in capabilities under normal circumstances. Once the cancerous cells "escape" the immune surveillance and clearance in the first time, their inherent immune "escape" ability and the ability to actively induce and suppress the immune system will enable the progress of cancer. Various indications indicate that during the long process of cancer development, innate immunity and acquired immunity always have the opportunity to recognize the presence of cancer and produce a corresponding response, but all aspects of this response are affected to varying degrees Or inhibition, and inhibition at the effect stage is the most deadly.

(2) Natural suppression of cancer cells

The continued existence of cancer immunity effectively blocks the widespread dispersion of cancer cells, and the immunosuppressive induction ability of cancer cells will continue to erode the immune system until it finally breaks through the immune barrier and erupts. The natural immunosuppressive ability of cancer cells effectively prevents themselves from being killed by the immune system; the existence of cancer immunity also puts cancer cells under an immune pressure and cannot "spread" at will; The ability of active inhibitory induction can gradually erode the immune system, making the balance between cancer and immunity gradually biased towards cancer, and eventually making the immune system "incompetent". Moreover, the erosion of cancer immunity by cancer cells is gradual, step by step, solid and effective, and it is almost impossible to reverse it. In addition, cancer cells can be enriched in cancer patients' peripheral blood, but human cancer metastasis has organ-selective characteristics, instead of being scattered or completely distributed with blood flow, and the incidence of metastasis is also much lower than predicted.

(3) The dialectical relationship between cancer and immunity

Based on years of basic research and clinical observations, the following three relationships between cancer and immunity are summarized: (A) The "flood and dam" relationship between cancer and immunity: It is mainly the blocking effect of innate immunity, just like the dam The blocking effect on the flood and the basic immunity formed by innate immunity can effectively prevent the growth of cancer and the extensive metastasis of cancer in various organs in the body. Therefore, the level of this basic immunity and the ability to maintain it may determine the speed of cancer growth and metastasis And breadth. (B) The relationship between "enemy and foe in war" between cancer and immunity: the effective suppression and killing effect mainly achieved by acquired immunity, and the effective "defense" force formed by acquired immunity can effectively kill cancer cells and reduce Cancer load plays an effective role in treating cancer and preventing cancer progression. (C) The relationship between "bad guys and policemen bribed by bad guys" in the relationship between cancer and immune reality in cancer patients: cancer cells reduce the expression of recognition signal molecules, local release of immunosuppressive factors such as TGF-, IL-10, etc. throughout the body Actively induces immune suppression, subverts the balance between normal immune activation and immune tolerance, etc., causing the body's immune system to gradually lose the immune function of cancer, and even to become the "accomplice" of cancer progression, enabling cancer to gradually evolve from "escape" immunity A major outbreak of advanced cancer that completely breaks through the immune barrier.

The new strategy for cancer treatment and cancer immunotherapy is "comprehensive cancer treatment combining cellular immune function remodeling and long-term maintenance." The nature of cancer, the genetic and cytological characteristics of cancer cells, and the characteristics of various cancer treatments determine that cancer treatment requires a new conceptual guidance and the use of new strategies. In cancer treatment, "do something and do nothing". on the one hand,

Most of the existing cancer biotherapies in China are based on DC-NK. Only a few cancer hospitals use DC, NK, T, and CIK multiple immune cell therapy biotherapies, so they can What we have learned is that there is still a certain gap between China's cancer biotherapy and foreign cancer biotechnology.
