Mr. Zhang, 63 years old, often felt that he had double vision in the last six months and also had a headache on his right side. He always thought that there was something wrong with his eyes until he later woke up every morning with some blood in the nasal snot sucked back from his nasal cavity. After the doctor’s examination, it was confirmed that Mr. Zhang was suffering from nasopharyngeal cancer. The treatment of nasopharyngeal cancer is based on radiotherapy, together with chemotherapy, and more than 80% of patients can be cured. After communicating with the doctor for many times, Mr. Zhang put down his psychological burden and went to the oncology department to receive radiotherapy and chemotherapy. In the process of chemotherapy, Mr. Zhang experienced nausea, vomiting, poor appetite, general weakness, hair loss, leukocyte and platelet reduction and other side effects. At this time, Mr. Zhang found a specialist in TCM department and hoped that instead of radiotherapy, he would only use Chinese medicine for conservative treatment. The expert told him that nasopharyngeal cancer can only be cured by radiotherapy, and it is normal to have certain side effects during the treatment process, and at this time, if he applies TCM evidence-based treatment, the side effects can be significantly reduced, and prescribed a Chinese medicine prescription for Mr. Zhang. Starting from the second cycle of chemotherapy, Mr. Zhang also cooperated with traditional Chinese medicine treatment, and the various symptoms appeared in front of him were significantly reduced, his appetite was also improved, and abdominal distension, nausea and vomiting basically disappeared. In fact, during chemotherapy for tumor patients, if the medicine can be used with evidence, it can significantly reduce various toxicity of chemotherapy. This actually reflects the role of chemotherapy to dispel evil and Chinese medicine to support righteousness. Immediately after the completion of two cycles of chemotherapy, Mr. Zhang’s second test came, when he started radiation therapy. If chemotherapy is compared to poison, which kills tumor cells, radiotherapy is like fire, which burns tumor cells. Therefore, in the course of radiotherapy for nasopharyngeal cancer, ulcers in the mucous membrane of the mouth and pharynx, painful swallowing, dry mouth and taste disorder will inevitably occur, and in severe cases, patients cannot eat at all. As the number of treatments increased, Mr. Zhang slowly developed the above symptoms. However, this time, with the previous experience, Mr. Zhang started to take oral medication together with Chinese herbal medicine at the beginning of radiotherapy, and at the same time, he applied topical medication to the skin of the radiotherapy site. Compared with other radiotherapy patients in the ward, during the whole course of radiotherapy, Mr. Zhang only had mild pain in his throat and eating was basically close to normal, which became a role model for radiotherapy patients. After completing all radiotherapy treatments, Mr. Zhang was relieved, but not long after, he developed symptoms such as dry mouth, poor appetite and general weakness. Worried about the recurrence and metastasis of his disease, Mr. Zhang found a TCM specialist again. After looking and listening to him, the specialist told him that this is a deficiency of both qi and yin, which is a common manifestation of patients receiving radiotherapy, and suggested him to take further TCM treatment after the treatment was finished, which would not only improve various symptoms significantly, but also reduce the recurrence and metastasis of tumor. After Mr. Zhang continued to take oral Chinese medicine, his dry mouth was gone and his appetite was better. When he met old acquaintances, people did not believe that Mr. Zhang was once a cancer patient who had gone through radiotherapy and chemotherapy. One of them is the multidisciplinary integrated treatment. Tumor treatment has left the era when surgical resection sang a one-man show. In fact, in this case of Mr. Zhang, we can see several important roles of Chinese medicine in tumor treatment. First, for tumor patients, many times radiotherapy is an essential means to cure the disease, but due to the toxic side effects of radiotherapy, many patients interrupt the treatment and lose the chance of cure, which is a great pity. Secondly, after surgery, radiotherapy and chemotherapy, tumor patients are often physically weak and also suffer from a variety of long-term adverse effects, such as poor appetite, poor spirit and weakness; Thirdly, after radiotherapy, the risk of recurrence and metastasis always exists, which brings a great psychological burden to patients, while the late treatment with TCM can effectively reduce the recurrence and metastasis rates; fourthly, for some advanced patients or diseases with poor effect after radiotherapy, such as liver cancer and pancreatic cancer, TCM becomes the only means of treatment for patients at this time. As a kind of palliative treatment, TCM can improve patients’ quality of life and prolong their survival time.
