Question 2: Can chemotherapy definitely cure cancer? 1. referred to as chemotherapy: drug treatment of diseases caused by pathogenic microorganisms, parasites and malignant tumors. Chemotherapy is not just for tumors. For example, drug treatment of tuberculosis is also called chemotherapy, which is the most commonly used treatment for tuberculosis. No matter what kind of cancer, it is possible to recover in early or late stage. Of course, its therapeutic effect is related to the severity of the disease and the patient's condition (including physical and psychological conditions). Therefore, it is necessary to cooperate with doctors to achieve the best treatment effect.
Question 3: Do you know what chemotherapy is for lung cancer? 1. What is chemotherapy for lung cancer?
Chemotherapy for lung cancer is the abbreviation of chemical drugs to treat lung cancer. It is a treatment method that uses chemical drugs to prevent the proliferation, infiltration and metastasis of lung cancer cells until the cancer cells are finally killed. It is a systemic treatment, and it is called the three major treatments of cancer together with surgery and radiotherapy.
Second, under what circumstances does lung cancer need chemotherapy?
1, stage I ~ Ⅲ A non-small cell lung cancer (NSCLC) is mainly treated by surgery, and chemotherapy is generally used as postoperative adjuvant therapy, and it can also be used as preoperative neoadjuvant chemotherapy for stage Ⅲ A patients.
2. Stage ⅴ patients are mainly treated with chemotherapy and can receive local palliative radiotherapy. Although there are many effective chemotherapy schemes for non-small cell lung cancer (NSCLC), the overall efficacy is not as good as that of small cell lung cancer (SCLC). The effective rate is generally 20% ~ 40%. It has been reported that increasing the dose can increase the strength of DN to about 50%, but most of them need hematopoietic factor treatment.
3. Patients with non-small cell lung cancer (NSCLC) rarely achieve complete remission through chemotherapy, so most patients can't get radical cure through chemotherapy. Need to cooperate with surgery or radiotherapy and other treatments.
4. The survival time of small cell lung cancer can be improved by radiotherapy, chemotherapy and surgery in the limited stage, but chemotherapy is the main method in the extensive stage, and the prognosis is poor.
Three, lung cancer chemotherapy matters needing attention
Due to the toxic effect of existing drugs, the interval of treatment can often last for several weeks after drug withdrawal, and should be carried out at intervals of 4 ~ 6 weeks from the date of starting chemotherapy every week, but the next course of treatment must be carried out after the toxic reaction of drugs disappears. During chemotherapy, special attention should be paid to drug withdrawal or dressing change.
At present, chemotherapy for lung cancer can not achieve a radical cure. Therefore, in a certain stage of chemotherapy, surgery or radiotherapy should be combined if possible to strengthen local or regional control of tumors. At the same time, a higher dose should be given according to the patient's tolerance. For lung cancer chemotherapy, a certain degree of digestive tract reaction and bone marrow suppression is inevitable, and the number of courses should be appropriately increased according to the patient's reaction and curative effect, so as to achieve complete remission as far as possible.
Chemotherapy for small cell lung cancer and non-small cell lung cancer.
1, common schemes for small cell lung cancer
The first-line schemes are EP and CE, EP is Vp 16 (etoposide) +PDD (cisplatin), or CBP (carboplatin) +Vp 16 (etoposide); The second-line scheme is Topotecan (Maxim) or Irinotecan (Caputo).
2. Common treatment schemes for non-small cell lung cancer
There are generally three first-line standard schemes: vinorelbine+cisplatin or carboplatin, paclitaxel+cisplatin or carboplatin, and gemcitabine+cisplatin or carboplatin. There is no obvious difference in curative effect, but there are differences in toxic and side effects.
At present, there are two second-line standard schemes commonly used in clinic: Docetaxel and Libitai. From the clinical trial and application, it has been used for many years and the curative effect is positive. It is a classic standard second-line scheme, but its side effects are too great. Libitai has just been listed for more than two years, and its clinical effect is very good. After pretreatment, the side effects are small and the patients are well tolerated.
3. Other programmes
Other regimens for non-small cell lung cancer include irinotecan (captopril), epirubicin, mitomycin, etc.
4. Chemotherapy has strong toxic and side effects, and it is easy to cause various uncomfortable symptoms during chemotherapy. Therefore, in the process of lung cancer chemotherapy, traditional Chinese medicine can also be used to enhance the curative effect, reduce the side effects of chemotherapy, inhibit and eliminate tumors, so as to achieve better therapeutic effects. Such as ganoderma lucidum (high concentration ganoderma lucidum preparation, medical grade ganoderma lucidum spore powder, etc. ) has excellent anti-chemotherapy effect, and its characteristics of strengthening body resistance and enhancing immunity can be used in any stage of tumor treatment.

Question 4: What are the symptoms of cancer patients after chemotherapy? The side effects of chemotherapy can be divided into short-term toxicity and long-term toxicity: short-term toxicity can be divided into local reactions (such as local tissue necrosis and thrombophlebitis) and systemic reactions (including digestive tract, hematopoietic system, heart reaction, pulmonary toxicity and renal insufficiency).
The long-term toxic reactions are mainly reproductive dysfunction, carcinogenesis and teratogenesis.
In addition, because of its toxic side effects, chemotherapy sometimes has complications, such as infection, bleeding, perforation, uric acid crystallization and so on.
Common side effects are as follows:
1, local reaction: phlebitis, local tissue necrosis.
2. Bone marrow suppression: Most chemotherapy drugs have different degrees of bone marrow suppression. Bone marrow suppression can be manifested as leukopenia, especially granulocytopenia. In severe cases, platelets, red blood cells and hemoglobin can all be reduced. At the same time, patients can also have symptoms such as fatigue, decreased resistance, easy infection, fever and bleeding.
3, gastrointestinal toxicity: most chemotherapy drugs can cause gastrointestinal reactions, manifested as dry mouth, loss of appetite, nausea, vomiting, and sometimes oral mucositis or ulcers. Constipation, paralytic intestinal obstruction, diarrhea, gastrointestinal bleeding and abdominal pain can also be seen.
4. Immunosuppression: Chemotherapy drugs are generally immunosuppressive drugs, which have different degrees of inhibition on the immune function of the body. When the immune function is low, the tumor is not easy to control, but it accelerates the process of recurrence or metastasis.
5. Nephrotoxicity: Some chemotherapy drugs can cause renal damage, mainly manifested as acute necrosis and degeneration of renal tubular epithelial cells, interstitial edema, renal tubular dilatation and severe renal failure. Patients may have low back pain, hematuria, edema and abnormal urine test.
6. Liver injury: The liver reaction caused by chemotherapy drugs can be acute and transient liver injury, including necrosis and inflammation, or chronic liver injury caused by long-term medication, such as fibrosis, steatosis, granuloma formation and eosinophil infiltration. Clinically, it can be manifested as abnormal liver function, pain in liver area, hepatomegaly and jaundice.
7. Cardiotoxicity: Clinically, it can be manifested as arrhythmia, heart failure, cardiomyopathy syndrome (patients are manifested as weakness, active dyspnea, paroxysmal dyspnea at night, and heart failure can cause rapid pulse, shortness of breath, hepatomegaly, cardiac enlargement, pulmonary edema, edema and pleural effusion. ), and the electrocardiogram is abnormal.
8. Pulmonary toxicity: A small amount of chemotherapy can cause pulmonary toxicity, manifested as interstitial inflammation and pulmonary fibrosis. Clinically, it can be manifested as fever, dry cough and shortness of breath. Most patients have acute onset and granulocyte increase.
9. Neurotoxicity: Some chemotherapy drugs can cause peripheral neuritis, which is characterized by numbness of fingers (toes), disappearance of tendon reflex, abnormal sensation, and sometimes constipation or paralytic intestinal obstruction. Some drugs can produce central nervous toxicity, mainly manifested as paresthesia, weakened vibration, numbness, tingling, gait disorder, ataxia, lethargy, mental abnormality and so on.
10, alopecia: some chemotherapy drugs damage hair follicles, and the degree of alopecia is usually related to the drug concentration and dose.
1 1, others: hearing loss, rash, flushing on face or skin, nail deformation, osteoporosis, bladder and urinary tract diseases, infertility, amenorrhea, sexual dysfunction, male mammary gland enlargement, etc. It may also be caused by some chemotherapy drugs.
