What are the targeted drugs for the c797s mutation?
If the C797S mutation appeared only after osimertinib treatment, it could be treated again with first-generation or second-generation targeted drugs such as gefitini. Amivantamab has a certain effect on osimertinib-resistant mutants caused by various EGFR mutations, including the C797S mutation. In addition, the fourth-generation egfr-targeted drug targeting the C797S mutation was still in the clinical research stage. Read more exciting novels for free
What are the targeted drugs for genetic mutation?
There were many types of targeted drugs that were made based on the genetic mutation characteristics of cancer cells. For example, targeted drugs for Kras gene mutation (commonly seen in patients with Colon cancer) include gefitini, regerafenib, sorafenib, bevacizumi, etc.; targeted drugs for the treatment of ERBB2 (also known as HEL2) mutation include trastubiza, pertubiza, lapatini, etc.; For the mutation of Braf15, it is suitable to use a combination of drafenib and trametini. In addition, targeted drugs such as gefitini, icotini, osimetini, bugatini, and other drugs with clear targets (e.g., ADC, ALK, etc.) were also made based on the principle of genetic mutation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Take the third generation of targeted drugs after the first generation of targeted drugs are resistant
After the first-generation targeted drug became resistant, the third-generation targeted drug could be considered. According to the data in document [2], after the first-generation targeted drug became resistant, only about 25% of patients had the opportunity to use osimertinib for second-line treatment. According to the study mentioned in document [4], the first-line use of osimertinib for the treatment of egfr-positive lung cancer, followed by comprehensive treatment methods such as chemotherapy and chemotherapy after drug resistance, the patient's overall survival time was 41.4 months, which was twice as long as the first-generation targeted drug. In addition, the document [5] mentioned the dual-target combination therapy plan, specifically the first-line treatment of the third-generation TKi osimertinib combined with the first-generation TKi gefitini, with a disease control rate of 100%. Therefore, for patients who were resistant to first-generation targeted drugs, third-generation targeted drugs might be an effective treatment option.
What are the targeted drugs for serous adenomas?
For high-grade serous adenomas, targeted therapy includes anti-neoplastic targeted drugs such as bevacizumi; for relapsed low-grade serous adenomas, Novartis targeted anti-cancer drug Mekinist (Trametini) has the potential to become a treatment option. In addition, in the treatment of malignant tumors, nirapalide tosylate capsules can be used as a targeted drug for maintenance therapy. For patients who overexpress HEL2/ neu, adding trastubiza (Herceptin) to standard chemotherapy can provide a new solution to improve the prognosis. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the targeted drugs that need to be tested?
In cancer treatment, genetic testing was usually needed to find suitable targets to determine whether targeted drugs could be used. For example, targeted drugs corresponding to mutations in genes such as EGFR, ALK, ROS - 1, BRAF, etc. in lung cancer needed genetic testing to determine the existence of the target before use. In addition, genetic testing was also needed to determine whether cetuxed could be used in the treatment of patients with benign or malignant tumors. However, targeted drugs such as domestic anlotinib, lenvatini, regorafenib, sorafenib, apitini, sunitini, cabotini, cediranil, bevacizumi, and olakumab, as well as bevacizumi in head and neck tumors (such as throat cancer, oral cancer, gum cancer, and other pathological squamous-cell cancer), did not require genetic testing. However, in general, it was more complicated to perform target testing for different tumor diseases and targeted drugs before use. It needed to be analyzed according to the specific situation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the types of targeted drugs in Henan?
It was known that 17 targeted drugs, including osimertinib, crizotinib, anlotinib, and afartinib, had entered the scope of reimbursement for Henan medical insurance, but it was impossible to determine all types of targeted drugs in Henan based on the available information. However, the common targeted drugs were the first-generation gefitini and erlotini, the second-generation aflatini and dacomitini, and the third-generation osimertinib. Monocentric antibody-type molecular targeted drugs such as trastuzumb (Herceptin), Rituexiu (Mebthera), EMC-C225 (cetoxieb, Erbitux), and Bevacizu (Avastin). Small molecular compounds were commonly used, such as Glivec (ST51, Imatini), Iressa (ZD1839, Gefitini), and OSI774 (Erlotini, Tarcava). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There are several types of breast cancer targeted drugs
There were mainly the following types of breast cancer targeted drugs: 1. Anti-neoplastic targeted drugs: There are intravenous preparations and oral drugs, but the effect in the treatment of breast cancer is not ideal. For example, bevacidol (Avastin) will be considered in some cases. 2. Anti-Her- 2 targeted drugs: targeted at HER - 2 positive patients, it is the most important targeted drug for breast cancer, mainly including trastuzumab (Herceptin), pertubizab, dm- 1, lapatini, etc. The prerequisite for use was that the patient was positive for HER - 2 (+++ in the immune tissue test). If the immune tissue test was ++, the patient would need to undergo a further FISH test. The patient could only be used if the FISH test was positive. If the immune tissue test was + or-, the patient could not be used. 3. A targeted drug for patients with fetal mutations in the Brca lineage: The main drug is olaparib, which is used to treat patients with metastasizing breast cancer who have harmful or suspected harmful mutations in the Brca lineage and who are negative for the human embryonic growth factor receptor 2 (HEL2). 4. Immune therapy (in a sense, it was also a targeted drug): Anti-PD- 1/PD-L1 Monoclone Antibodies, which essentially relieved immune suppression and activated immune cells to kill cancer cells. 5. mTO inhibition drugs, such as everolimus and sirolimus, can inhibit the activation of the mTO signaling pathway, thereby suppressing the growth and metabolism of tumor cells. 6. Other targeted therapy drugs, such as Parp inhibition drugs, CD 4/6 inhibition drugs, etc. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is it always effective to take targeted drugs for lung cancer?
The effect of targeted drugs on lung cancer patients was not very good. Target drugs could not cure lung cancer. Although they could prolong survival time, they could not always be effective. There were very few driver mutations in lung cancer, so there were relatively few targeted drugs that could be used. When using targeted drugs, it was necessary to find the target of lung cancer and could not be used blindly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What targeted drugs can be taken for oral cancer?
The targeted drugs for oral squamous-cell cancer included pabolizumab injection, trastubizab for injection, erlotinib, gefitinib, cetuxed, nivaliumab, etc. Pabolizub injection can be used to treat advanced non-small cell lung cancer, advanced gastric cancer, oral Squamoma, etc.; Trastuzu for injection can be used to treat metastasized breast cancer, metastasized gastric cancer, oral Squamoma, etc.; Erlotinib is suitable for patients with advanced non-small cell lung cancer who have a mutation in Exon 19 or L858 of the Epidermal growth factor receptor Tyrosin Kinase gene. It can block the egf-signaling pathway to inhibit the growth of tumor cells; Gefitini can be used for the treatment of patients with locally advanced or metastasized non-small cell lung cancer who have failed at least one previous chemotherapy program. It can selectively inhibit the activity of EGFR protein protein. Cetuxed is suitable for the auxiliary treatment of RAS gene wild-type Colon Cancer, Rectal Cancer, and Stomach Cancer. It can be used in combination with radiation to improve the efficacy. Nivaliumab is suitable for the treatment of patients with advanced liver cancer who have failed previous systematic treatment. It activates T cells, allowing them to recognize and attack tumor cells that express the PD - 1 receptor. When using these drugs, you must follow the doctor's advice and pay attention to their respective conditions and precautions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the side effects of general targeted therapy drugs?
The side effects of targeted therapy mainly included the following aspects: 1. Digestive tract reactions: The targeted drug may stimulate the digestive tract, causing nausea, vomiting, diarrhea, abdominal distension, and other symptoms. This is a relatively common side effect. In addition, the combination of targeted drugs and chemotherapy may also cause a digestive reaction. 2. Liver and kidney toxicity: The drug may be digested in the liver or kidneys after blood circulation, which may increase the burden on the liver and kidney. When used in large doses, it may cause liver and kidney incompetence. 3. Fetal toxicity: Some special targeted drugs have fetal toxicity, such as trastuzumi, which easily passes through the placental barrier and may cause fetal abnormality. Pregnant women should avoid using such targeted drugs with strong fetal toxicity. 4. Others: Fever, chills, bone marrow suppression, allergy (very few patients are allergic to the targeted drug components), and other conditions may occur. In patients treated with Herceptin, symptoms and signs of decreased cardiac function may occur. During the period of taking the medicine, there may be adverse reactions such as peeling, pain, inflammation, etc. In addition, a sudden increase in dosage would cause fluctuations in blood concentration, affect the efficacy, accelerate drug resistance, and even cause serious adverse reactions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
