For a long time, the conventional treatment of malignant tumors cannot be separated from surgery, chemotherapy and radiotherapy. All these methods are hoped to eliminate the lesions completely, but to a certain extent, they inevitably damage the normal structure and function of the body. Therefore, for those patients who are advanced and old and weak, not only are they poorly tolerated, but also the efficacy of treatment is not good. The “green treatment” mode of malignant tumor is aimed at the old and frail patients who have failed radiotherapy; it is mainly based on local minimally invasive surgery + natural traditional Chinese medicine or (and) biological targeted therapy; it is aimed at prolonging the survival period and improving the quality of survival; it is characterized by low damage and repeatable treatment; and the local minimally invasive means are diverse. The “green treatment” advocated by our hospital is gradually forming a new system of tumor treatment. Malignant tumor in Chinese medicine is a kind of evil that combines yin and yang. In Chinese medicine, there is a theory that “the solitary yang cannot be born and the solitary yin cannot grow”. Applying the method of “microscopic identification” and with the help of modern diagnostic techniques, we can clearly see the obvious occupancy of the tumor in the body, and its body has shape and signs, which is “yin”, that is, the tumor “body is yin”. “The tumor has a tendency to grow and develop, and the local temperature increases, which has the function of “Yang moving”, i.e. “use as Yang”. Therefore, according to Chinese medicine, malignant tumor is a kind of evil that combines yin and yang and has the property of life. The tumor is parasitic in the body, connected with the blood vessels of the five viscera and six bowels, similar to a pathological organ, forming the four main characteristics of Yin in the body and Yang in the body, easy to move around the body and take away the qi and blood. With the continuous progress of modern technology, especially the use of advanced PET/CT, it can clearly show that between tumor tissues and normal tissues, there are some tissues with relatively strong metabolism. Combined with the concept of TCM surgery, we believe that this is the extension of the so-called “protective field” in TCM. In the “Golden Guide to Medicine”, it is written that the “protective field” is a furuncle surrounded by redness and swelling that does not dissipate. The existence of “protective field” means that the positive qi can still restrain the evil qi, and it can also be said that “protective field” has the ability to limit the metastasis of tumors. In long-term clinical practice, it was found that after minimally invasive treatment with argon helium knife for lung cancer patients, under the dual monitoring of PET/CT structure and function, it was found that the remaining paracancerous tissues, i.e. “protective field”, restrained the development of tumor foci, and patients could achieve better long-term results. The relationship between tumor and its surrounding tissues in terms of “protective field” explains the pathogenesis of tumor metastasis from a new perspective, which provides an entry point for Chinese medicine research on the prevention and treatment of tumor metastasis and spread. The treatment does not need to pursue the “elimination of evil”, as it is said in “Nei Jing”, the treatment of big toxins is to remove six of ten; the treatment of regular toxins is to remove seven of ten; the treatment of small toxins is to remove eight of ten; the treatment of no toxins is to remove nine of ten; the treatment of grain, meat, fruit and vegetables is to be exhausted by food and nourishment, not to make it too much, which hurts its righteousness. Not exhausted, the line again as the law. The sage is hanging, this strict precautions, is the blessing of all generations. Su Wen? It can be seen that Chinese medicine treatment, not to the doctor completely, completely wipe out the evil, more important is to always pay attention to protect the patient’s “righteousness”. The “righteousness” is the core means to resist the “evil”, and the doctor’s task is to break the negative situation of the righteousness in the fight between the good and the evil. This is to follow the two major principles of external treatment in Chinese medicine, one is to fight against the evil qi and at the same time to protect the positive qi, so the pursuit of technology is minimally invasive or even non-invasive; secondly, when we encounter patients who have metastasized, that is, “the disease of great evil”, we can attack the main tumor lesions, break the balance between positive and evil, and achieve the result of suppressing the evil qi and supporting the positive qi. Research has found that there is a significant imbalance between the effects of malignant tumors on the whole body and the local area. Patients with malignant tumor usually have different manifestations of overall deficiency and cold and local reality and heat. As the tumor grows and multiplies, it will consume a lot of yang and yin blood; qi deficiency will not be able to rate the blood flow, the pulse channels will not be filled enough, and the limbs and muscles will not be nourished, making the circumference tired and weak; qi imbalance, the clear yang will not rise, and the clear orifices will not be nourished, resulting in mental sleepiness and depression or even confusion; qi and blood imbalance affects water and fluid metabolism, causing water-dampness not to transform, resulting in edema or cavity effusion, etc. Therefore, it is necessary to separate the local from the whole body “deal with”. Internal disease external treatment” is one of the characteristics of TCM “Internal disease external treatment” is one of the characteristics of TCM treatment, including the external application of Chinese medicine, acupuncture, massage, channeling and other methods, with direct action, convenient operation, less toxic side effects, etc., in the clinic has also been It has been widely used in clinical practice. The external application of Chinese medicine is to absorb the medicine directly into the skin or mucous membrane, thus exerting therapeutic effects. When discussing the effect of ointment, “The Encyclopedia of the Rational Boiling” points out that one is to pluck and the other is to cut, where the disease has been agglomerated, plucking will make the disease come out without the risk of deep internal trapping, and where the disease passes through, cutting will break the evil without the risk of delusional transmission. In the treatment, because the tumor is connected with the blood vessels of the body, it is easy to make the treatment fall into a difficult situation because of the loss and glory of the tumor. Therefore, the treatment of tumor should be preceded by external treatment technique, firstly using “cutting method” to cut off the blood connection between tumor and body, and then using “extraction method” to destroy its root. After the destruction of the tumor, the internal medicine will be used to regulate the tumor, not only to supplement the deficiency of the body, but also to remove the remaining evil, so as to prevent the resurgence of the tumor. “Green treatment” advocates the maximum protection of the body’s positive energy. Unlike the conventional treatment mode, “green treatment” for malignant tumors has the primary goal of maintaining the patient’s survival quality. Under the guidance of traditional Chinese medicine theory, this treatment incorporates modern minimally invasive technology into the Chinese medicine surgical system, modernizes Chinese medicine surgical technology, realizes the combination of internal and external treatment, and advocates the pursuit of therapeutic effect under the premise of maximizing the protection of the body’s vital energy, which is sustainable, repeatable, low-injury and easily tolerated. The concept is not only of special significance to patients with advanced tumors, elderly tumors and those who have failed conventional treatment, but also a useful attempt to modernize TCM treatment techniques. The three-stage therapy of “interception and extraction, attack and supplementation, and reconciliation”. Combined with long-term clinical experience, we have formed a three-stage “green treatment” model of “intercepting, extracting, tapping and tonifying”. Phase I: Local treatment The treatment should first identify the tumor locally, and then use modern minimally invasive technology to directly solve the main contradiction. Usually, the main focus is on “elimination”, which is to quickly ablate local lesions, remove local evil energy, reduce tumor load, and stimulate systemic immune response at the same time. Among them, modern minimally invasive techniques mainly use argon helium knife local cryoablation, microwave ablation, radiofrequency ablation, ultrasound focusing, photodynamic technology, DSA vascular intervention, vertebroplasty, thermal perfusion and so on. After that, appropriate TCM methods and drugs are selected, such as external application of TCM, external washing, enema, fumigation, local tumor injection, TCM infusion, as well as embolization and peri-medication, etc., which can act on tumor locally with clear target, direct effect and low systemic toxic side effects, and easily and effectively relieve local problems such as cancer pain, ulcer, intestinal obstruction and fluid accumulation caused by tumor. Stage 2: Systemic conditioning According to the systemic diagnosis, the main method is to strengthen the spleen and remove the turbidity, and the purpose is to restore the function of spleen and stomach to separate and secrete the turbidity, and the treatment rules are mainly based on “tonification”. Among them, the main application of Chinese medicine is to expel the evil, mainly using small poisonous drugs and insects, such as raw half summer, whole scorpion, toad skin, centipede, white flower snake, etc.; the main application of corrective drugs such as Fu Ling, Atractylodes macrocephala, Radix Codonopsis pilosulae, Radix Rehmanniae, etc., so that “if the righteousness exists within, the evil cannot dry up”. To expel the evil without harming the positive, improve the internal environment of the organism, make the internal organs balanced and well-developed, and enhance the ability of the organism to resist the evil. The third stage: adjusting the physical constitution Chinese medicine treatment is mainly used to harmonize the qi, blood, yin and yang of the organism, and to adjust the physical constitution mainly by the method of “harmony”. The formula is based on Jing Yue Quan Shu Wu Fu Drink (Ginseng, Radix Angelicae Sinensis, Atractylodes Macrocephala, Radix Rehmanniae Sinensis, Glycyrrhiza Glabra) and Si Wei San, etc. By analyzing the patient’s physical condition and identifying the evidence, we can change the internal environment to make it unfavorable for cancer survival and prevent recurrence.
