Chemotherapy is indispensable to the treatment of most cancers, so is breast cancer, but what is the chemotherapy regimen for breast cancer? Many people are not very clear about breast cancer chemotherapy regimen, so in order to let you understand more clearly, we have introduced the breast cancer chemotherapy regimen today. Chemotherapy is the most advanced treatment method in cancer treatment in recent years. However, chemotherapy drugs are often “unclear” and “indistinguishable”, killing tumor cells as well as normal cells in the body. Therefore, the following toxic effects and adverse reactions may occur in chemotherapy, so it is important to develop a chemotherapy regimen for breast cancer: 1. When intravenous chemotherapy drugs are injected, inadvertent leakage of the drug may cause local tissue necrosis and embolic phlebitis. Therefore, health care workers must be very careful to prevent them; 2. Inhibit the bone marrow hematopoietic system, mainly the decline of white blood cells and platelets. Before each chemotherapy, should do a blood test, if the number of white blood cells below (2.5 ~ 3) × 109 / liter, platelets (50 ~ 80) × 109 / liter, should temporarily stop chemotherapy, follow the doctor’s orders to use drugs to raise blood cells. In addition to the existing treatment with shark liver alcohol, blood lysine, nucleotides and vitamin B6, as well as Chinese herbal medicine to benefit the blood, some colony-stimulating factors produced by recombinant genetic engineering in recent years have obvious functions to promote blood cell proliferation. 3.Irrational chemotherapy regimen for breast cancer can damage liver cells to varying degrees, resulting in increased glutamate transaminase, rising bilirubin, hepatomegaly, pain in liver area, jaundice, etc., which can cause liver cirrhosis and impaired coagulation mechanism in serious cases, so liver function should be checked before and during the course of chemotherapy to detect and solve problems in time. 4, some chemotherapy drugs have toxic effects on the cardiovascular system, serious heart failure can occur. Therefore, the electrocardiogram should be checked before and during the use of drugs, and abnormalities should be stopped immediately and treated in a timely manner. For patients with heart disease, avoid using chemotherapy drugs that have toxic effects on the heart. 5, toxic effects on the respiratory system and adverse effects of chemotherapy drugs can cause acute chemical pneumonia and chronic pulmonary fibrosis, and even respiratory failure. Therefore, with pulmonary toxic drugs (i.e. chemotherapeutic drugs with toxic effects on the respiratory system), such as contracycline, the lungs should be checked regularly during the use of the drug, and follow-up visits should be paid attention to after discontinuation of the drug. If pulmonary toxicity is detected, the chemotherapy regimen for breast cancer should be stopped immediately and treated with hormones; 6. Toxic effects and adverse reactions in the urinary system include proteinuria, oliguria or anuria, and in some cases, hematuria. In order to have a clear understanding of kidney function, it is important to have regular check-ups before and during the course of medication to detect problems and treat them in time. In the treatment, we should drink more green tea and take diuretic and laxative herbs so that the daily urine volume is 2000-3000ml. Experience shows that this can reduce the toxic effects and adverse reactions of the urinary system; 7, improper use of drugs in the chemotherapy regimen for breast cancer can affect fertility and lead to malformations. During chemotherapy, male patients should be sterilized and female patients should discontinue or avoid chemotherapy if they have pregnancy. 9, among the systemic reactions of chemotherapy, the toxic effects and adverse reactions of the digestive system are the most troublesome for patients, such as nausea, vomiting, loss of appetite, abdominal pain, diarrhea, as well as oral mucosal ulcers, pharyngitis, etc.
