Long-term clinical practice has led us to the important experience that patients should make good use of traditional Chinese medicine to zero-toxicity chemotherapy in the intervals between radiotherapy and chemotherapy, and seize the three major links of tumor inhibition, enhancement of immunity and elimination of clinical symptoms caused by radiotherapy. This will not only ensure the smooth progress of radiotherapy, but also greatly reduce the possibility of metastatic recurrence. At present, radiotherapy and chemotherapy are still the main methods of cancer treatment. However, radiotherapy and chemotherapy can kill normal cells while killing cancer cells, and also lead to gastrointestinal dysfunction, bone marrow suppression and other toxic side effects; in particular, it destroys the immune system of the human body, which can lead to concurrent infections and failure of human body functions in serious cases. Therefore, if immune repair is not carried out in time after radiotherapy, metastatic recurrence of cancer can be aggravated. Reasonable application of traditional Chinese medicine can help eliminate the toxic side effects of radiotherapy and avoid the metastatic recurrence of cancer. Generally, radiotherapy will affect the digestive function, and even anorexia, nausea and vomiting will affect eating. However, the regenerative ability of gastrointestinal function is very strong, especially in middle-aged and strong-aged people, and it usually recovers naturally. In my experience, there are two general principles during chemotherapy: 1. Let nature take its course. Some family members, in order to promote early recovery, force patients to eat more and eat good (highly nutritious) food. But this is often counterproductive, due to the damage of gastrointestinal function, not only can not be absorbed, but also add discomfort. At this time, the diet should be light, or change to easily absorbed and digested semi-liquid, such as porridge and soup. If the vomiting is severe, stop eating one or two meals is not a bad idea. After the recovery of gastrointestinal function can be appropriate to increase nutrition, including some high-protein, high-nutritional food, but there must be a “degree”. Radiotherapy patients can be appropriate to add some silver ear, lily and other nourishing Yin products, because radiotherapy is very easy to damage the body fluid. 2, radiotherapy during the Chinese medicine must also be adjusted. Radiotherapy to clear heat and nourish yin to be, but not too nourishing; chemotherapy to protect the stomach, and the stomach first, such as the patient’s reaction is more dramatic, may wish to stop the soup for two or three days, conducive to the gastrointestinal “recuperation”. In radiotherapy, the decline of white blood cells is inevitable, patients do not need to panic, should actively cooperate with various methods to raise white blood cells. If it is in the intermittent period of chemotherapy, from the next chemotherapy time is shorter, and the white blood cell decline is very obvious, the application of leukocyte may not be, but this kind of treatment there is always the suspicion of gouging out the flesh to make up for the sores. In fact, certain components in Chinese medicine can not only inhibit and kill cancer cells, but also protect the immune function. I once met a patient with advanced ovarian cancer, who had severe bone marrow suppression after chemotherapy, with white blood cells dropping to 1100 and whole blood lowering.
