One weekend in April this year, I was referred by a friend to consult a young patient in Changsha, Hunan Province. The patient is a girl, only 28 years old, with a young daughter. The patient was admitted to the emergency room of Xiangya Medical College Hospital. 2 months ago, she developed a headache, which she thought was a cold, but it was getting worse and worse, and when it was severe, the headache was splitting, and she went to the hospital and found multiple intracranial occupying lesions, which are usually considered metastases in this case. Because one of the intracranial masses was located in the brainstem, many hospitals were afraid to administer radiotherapy and had to give dehydration treatment several times a day. When I saw the patient, he was completely bedridden, and he would wake up with severe dizziness. He was dehydrated with mannitol six times a day, but with a slight delay, he developed headache and jet-like vomiting. I was sad to see this still childish face. The patient’s brother had already consulted with a specialist oncology hospital and Peking Union Medical College Hospital in Beijing and had done genetic testing, and there was no mutation in EGFR, which meant that the patient was not suitable for targeted therapy. After reading the patient’s CT film carefully, there were 6 intracranial occupancies, and the largest lesion was in the cerebellum, with a diameter of 2cm. With my years of experience, I thought that the patient’s time was short, and mobilized the patient again to go to Beijing for brain radiotherapy. But the operational difficulties were difficult to overcome, and the dehydration treatment alone six times a day made the journey exceptionally hopeless. So with the attitude of giving it a try, I carefully conducted a TCM dialectic and prescribed herbal medicine. The patient had dizziness and headache as the main symptoms, with occasional nausea and vomiting, dry mouth and bitterness, dry stool, which did not work for several days, red tongue without coating, and fine pulse. Although he had primary lung cancer, he had no lung symptoms, so he was suffering from actual symptoms and deficiency. The patient is young and usually irritable. Therefore, the patient was given Tian Ma and Hooked Vine Drink to calm the liver and calm the wind. (After taking the medicine, the patient’s headache was gradually reduced, but the number of dehydration was reduced. 1 month later, the patient returned to his place of origin and used dehydration medicine 3 times a day, the dizziness was significantly reduced and he could walk alone. 3 months later, the patient’s brain CT film was rechecked and the edema was significantly reduced, the intracranial tumor was stable, the patient’s physical strength was significantly improved and he could take care of himself. The patient’s family responded by phone that the patient’s symptoms were stable, and dehydration treatment was administered 1-2 times a day, and Chinese herbal medicine continued to be applied. Through this case, I was greatly shocked. Being an oncologist for 26 years, in my subconscious, I always thought that traditional Chinese medicine could only play an adjuvant role, and the anti-tumor still depended on chemotherapy and radiotherapy, so the conventional treatment always mobilized patients who had the opportunity to undergo radiotherapy and chemotherapy, and had no confidence in pure traditional Chinese medicine treatment. In fact, in this case, if radiotherapy was definitely done at that time, it was likely to cause brain herniation and death due to the initial edema of radiotherapy. Therefore, the radiotherapist was right to be cautious in not giving radiotherapy. The patient was found to have stage 4 lung cancer, which is highly malignant and in a period of rapid tumor progression. It was proved that traditional Chinese medicine can inhibit tumor development and survival with tumor is feasible.
