Answer the first question: What is the current status of colorectal cancer treatment?
According to the current international best level, stage I, II and III colorectal cancer must first receive surgical treatment before it can be cured. The recurrence and metastasis rate after radical surgery is 50%, and stage I surgery does not require chemotherapy or radiotherapy, and the recurrence and metastasis rate is less than 10%; Whether to accept chemotherapy or radiotherapy after stage II surgery is controversial, and the recurrence and metastasis rate is below 30%; The recurrence and metastasis rate of high-risk stage II and stage III patients is as high as 50% or more. If they receive chemotherapy or radiotherapy after surgery, the recurrence and metastasis rate can be reduced to about 30%. The recurrence and metastasis time mostly occurs within three years. Regular review (once every three months within two years after surgery, and once every six months in the next three years) can find the condition in time, which is crucial for the next step of treatment. The work of the Oncology Department of Xiyuan Hospital in recent ten years has confirmed that the recurrence and metastasis rate of patients with stage II and III colorectal cancer can be reduced to 14% by adding traditional Chinese medicine treatment (TCM syndrome differentiation and treatment decoction+oral Chinese patent medicine) on the basis of conventional western medicine treatment. If it is a stage IV patient, it is impossible to cure. Without treatment, the survival period should be about half a year to one year. With the best chemotherapy drugs, the median survival period has exceeded 17 months. With targeted treatment drugs, the median survival period can be as high as 24 months. This effect is much better than that of lung cancer or gastric cancer.

Answer the second question: How should I find a doctor when I get colorectal cancer?  
After the diagnosis, we should find Western doctors (surgery, internal medicine, radiotherapy department) and Chinese doctors at the same time, because in the whole process of cancer, we need comprehensive treatment first, and there is no radical cure without surgery; Without postoperative adjuvant chemotherapy and radiotherapy, the recurrence and metastasis rate is high; Therefore, patients will benefit only if they listen to the opinions of doctors in surgery, internal medicine and radiotherapy and work out long-term treatment plans. Especially in the early stage of the disease, do not rush to operate before the condition is known. If it is stage IV, chemotherapy should be the first choice, and blind surgery will not benefit the patient.
In all stages of colorectal cancer, traditional Chinese medicine is suitable for application. Before early surgery, the application of traditional Chinese medicine can improve the patient's physique and improve the tolerance to surgery; After surgery, traditional Chinese medicine can promote the recovery of the body and help eliminate residual tumor lesions; The combination of traditional Chinese medicine and radiotherapy and chemotherapy can not only improve the efficacy of radiotherapy and chemotherapy, but also reduce the side effects of radiotherapy and chemotherapy. After postoperative chemotherapy and radiotherapy, long-term use of traditional Chinese medicine can also prevent the recurrence and metastasis of tumors; In the late stage of cancer, the application of traditional Chinese medicine can improve the survival time and quality of life of patients, or make patients live with tumors for a long time. Therefore, TCM should be seen in the whole process at an early stage.

Answer the third question: What kind of Chinese medicine students should we look for?  
Modern Chinese medicine should be sought for treatment. Modern Chinese medicine refers to the clinician in the oncology department of the TCM general hospital or the TCM department of the Western medicine oncology hospital. They have received formal training in both traditional and western medical systems. Their fundamental difference from the old Chinese medicine lies in their understanding of modern medicine and their ability to use modern medical diagnosis and treatment methods for diagnosis and treatment; The fundamental difference between western medicine and traditional Chinese medicine is that they have two sets of treatment methods, which can learn from each other. Modern society needs modern Chinese medicine. Because of the particularity of tumor specialty and the increasingly detailed division of medical work, tumor patients should also be specialized in seeking TCM treatment, that is, seeking TCM oncology treatment, in order to receive the best effect. TCM treatment of tumor also emphasizes comprehensive treatment. In a broad sense, TCM treatment is part of comprehensive treatment of tumor; In a narrow sense, TCM comprehensive treatment of tumor is based on the different stages of the tumor, making rational use of all existing TCM treatment methods; Oral, intravenous, enema, external application, acupuncture, Qigong, sound therapy, dietotherapy, intervention, etc. are organically combined with the comprehensive treatment of Western medicine to achieve the best therapeutic effect. At different stages of the development of tumor lesions, the status and role of traditional Chinese medicine treatment are different: 1. In the prevention of high-risk groups of tumors, traditional Chinese medicine treatment plays a leading role in preventing canceration, and can take the decoction of syndrome differentiation and treatment for a long time; 2. After surgical resection of stage I tumor, most patients do not need adjuvant radiotherapy and chemotherapy. Traditional Chinese medicine treatment plays a leading role in preventing cancer metastasis and recurrence. They should take traditional Chinese medicine for 3-5 years and take regular reexamination. 3. After surgical resection of stage II and III tumors, most patients need postoperative adjuvant radiotherapy and chemotherapy to prevent metastasis and recurrence. This period of traditional Chinese medicine treatment is to increase the sensitivity of radiotherapy and chemotherapy and reduce the side effects of radiotherapy and chemotherapy. After the end of radiotherapy and chemotherapy, it is still necessary to take traditional Chinese medicine for a long time to prevent metastasis and recurrence. At least 3 years of traditional Chinese medicine decoction treatment based on syndrome differentiation and regular review. 4. In Phase IV, there are two cases. For some radiochemotherapy sensitive tumors, such as lymphoma and small cell cancer, if the patient's physical condition is good, they should be treated with integrated traditional Chinese and western medicine, and radiochemotherapy plus Chinese medicine sensitization and toxicity reduction should be used to fight tumors; When the tumor is not sensitive to radiotherapy and chemotherapy, or the patient's physical condition is poor, comprehensive treatment of traditional Chinese medicine should be given priority to strengthening the body and eliminating pathogens, improving the quality of life and prolonging the survival period. In a word, TCM treatment can run through the whole process of tumor treatment.
To treat tumors, we must find a specialist in a regular hospital. Traditional Chinese medicine treatment can run through the whole process of tumor treatment, but in many cases, simple Chinese medicine treatment will also delay the patient's condition, especially for folk visiting doctors who cannot find Western medicine. On the one hand, we should count the efficacy of western medicine such as chemotherapy and radiotherapy on our own (the efficacy of radiotherapy can last for half a year), On the one hand, because the side effects of chemotherapy can not be liberated, the abuse of traditional Chinese medicine to dispel pathogens leads to fatal toxicity, on the other hand, it can also make patients spend more money.
At present, there is no specific Chinese medicine for the treatment of tumors. There are many kinds of anti-cancer drugs in the public medical catalogue, including intravenous drip and oral administration, which have been strictly reviewed and approved by the national drug administration department. They are safe and effective enough for clinical use. There is no need to pursue various anti-tumor drugs and supplements at your own expense. The syndrome differentiation and treatment decoction is the most individualized treatment plan, which should be applied from beginning to end. The best sign of effectiveness is: comfortable after taking the medicine, no adverse reactions, followed by reducing symptoms.
At present, various treatment methods commonly used in traditional Chinese medicine:
1. Traditional oral Chinese medicine decoction: It needs to be prepared by TCM doctors based on syndrome differentiation and treatment after four diagnosis and reference. As the best individualized treatment method, it should be used continuously throughout the tumor treatment to receive the best effect.
2. Traditional Chinese patent medicine oral preparation: suitable for patients with malignant tumors at all stages. Generally, the medicine of decoction, which is mainly used to expel evil spirits and mainly used to strengthen the body, can make up for the disadvantage that some toxic and evil spirits dispelling medicines are not easy to be used in decoction preparations. The commonly used Chinese patent medicines for dispelling pathogens include cinobufacin tablets, Pingxiao capsules, Xihuang pills, compound cantharides capsules, etc. The Fuzheng Chinese patent medicines include Zhenqi Fuzheng capsules, Bazhen granules, Shengmai oral liquid, etc.
　　3.  External preparation of traditional Chinese medicine: It is applicable to the pain relief treatment of skin metastasis or liver metastasis of colorectal cancer.
　　4.  External plaster of traditional Chinese medicine: It is suitable for the treatment of hydrothorax and ascites, pain relief and superficial metastasis.
　　5.  Anal suppository of traditional Chinese medicine: analgesic, anti-inflammatory, intestinal metastasis tumor treatment.
　　6.  Traditional Chinese medicine intravenous preparations: suitable for patients with colorectal cancer at all stages and stages, there are two kinds of preparations, namely, righting and expelling pathogenic factors. The righting ones include Shengmai injection, Shenfu injection, etc., and the expelling ones include Kushen injection, cinobufagin injection, elemene emulsion injection, etc.
　　7.  Other TCM auxiliary treatment (Qigong, acupuncture, dietotherapy, sound therapy, medicine bath, psychology): suitable for patients with colorectal cancer at all stages.
Timing of medication and treatment mode
　　1.  Patients after radical surgery before stage III:
During the period of radiotherapy and chemotherapy - TCM comprehensive treatment assists radiotherapy and chemotherapy, improves the tolerance and sensitivity of radiotherapy and chemotherapy, and focuses on strengthening the body, and does not advocate dispelling pathogenic factors. Chinese medicine decoction, Chinese patent medicine, auxiliary Chinese medicine treatment can be used, and intravenous drip preparation can be used if conditions permit.
After radiotherapy and chemotherapy - anti metastasis, anti recurrence, strengthening the healthy and expelling the evil at the same time, long-term use of traditional Chinese medicine for 3-5 years, to restore human immune function. Traditional Chinese medicine decoction and Chinese patent medicine can be used, and intravenous drip preparation is not recommended.
　　2.  Phase IV patients: patients with cancer that has recurred and metastasized. Although the current treatment level cannot be cured, the combination of traditional Chinese and western medicine can extend the median survival period to more than 24 months, which is significantly better than the 12 months and 10 months of non-small cell lung cancer and gastric cancer. Especially, the efficacy of colorectal cancer is getting better and better with the continuous emergence of western medicine chemotherapy and new targeted treatment drugs, We have seen the dawn of healing. Patients with advanced colorectal cancer have two options:
1) Good physical condition (ECOG0-1, or Karnaugh score>60, and weight loss<5%), positive excess of pathogenic factors, combination of traditional Chinese and western medicine treatment, radiotherapy or chemotherapy or targeted treatment drugs to eliminate pathogenic factors to the maximum extent, comprehensive treatment of traditional Chinese medicine to improve the tolerance and sensitivity of radiotherapy and chemotherapy, focusing on strengthening the body, without eliminating pathogenic herbs. Chinese medicine decoction, Chinese patent medicine, auxiliary Chinese medicine treatment can be used, and intravenous drip preparation can be used if conditions permit.
2) The physical condition is poor (ECOG>2, or Karnaugh score<60, and weight loss>5%), and the patients can not accept radiotherapy or chemotherapy. TCM comprehensive treatment is mainly used to improve the patients' immune function, improve their quality of life, extend their survival period, strive for survival with tumors, and promote both the healthy and the evil. All TCM comprehensive treatment methods can be used.
3) The patient has stomach qi to eat, and the healthy qi is not failing. The main content of the comprehensive treatment of traditional Chinese medicine is: Chinese medicine decoction plus Chinese medicine anti-tumor preparation plus Chinese medicine intravenous preparation.
4) The patient can't eat without stomach qi, and the healthy qi has declined. The main content of comprehensive treatment of traditional Chinese medicine: Chinese medicine decoction plus Chinese medicine intravenous preparation plus intravenous nutrition support.
