Clinical significance of NGS second-generation sequencing

NGS second-generation sequencing, namely high-throughput sequencing or Next Generation Sequencing, has far-reaching significance in clinical practice, especially in the fields of genetic disease screening, prenatal diagnosis, tumor diagnosis and treatment. The following are the specific significance of NGS second-generation sequencing in clinical practice:

NGS second-generation sequencing

1. Screening and Diagnosis of Genetic Diseases Through NGS testing, doctors can detect mutations in specific gene regions, which helps to accurately diagnose a variety of hereditary diseases. This technology not only improves the accuracy and efficiency of diagnosis, but also provides strong support for the prevention and treatment of genetic diseases. For example, for some single-gene genetic diseases, NGS testing can provide fast and accurate diagnosis, winning valuable time for patients to obtain effective treatment in a timely manner.

2. Prenatal testing and diagnosisPregnant women can undergo DNA blood tests through NGS testing to screen for genetic diseases, avoiding the limitations and risks of invasive examinations through amniotic fluid extraction through amniocentesis. This non-invasive prenatal testing technology not only improves the accuracy of the test, but also greatly reduces the risks of pregnant women and fetus, providing strong guarantees for eugenics and eugenics.

3. Clinical diagnosis and treatment of tumorsNGS detection plays a crucial role in the clinical diagnosis of tumors. It can detect genetic mutations in tumor cells and provide an important basis for the diagnosis and treatment of tumors. Specifically, the significance of NGS detection includes the following aspects: 1. Clarify tumor gene mutations: NGS detection can detect more, wider and more complete gene loci at one time, identify various tumor-related gene mutation types, and help doctors more accurately understand the patient's tumor gene status. 2. Guide the selection of therapeutic drugs: Through NGS testing, doctors can understand the patient's metabolism and response to drugs, thereby formulating individualized drug use plans for patients. For example, for certain specific gene mutations, doctors can choose corresponding targeted drugs for treatment, which improves the therapeutic effect and reduces side effects. 3. Predict treatment effect and survival time: NGS testing can also guide cancer chemotherapy plans, predict patients' treatment effect and survival time, and provide a basis for doctors to formulate more reasonable treatment plans. 4. Explore new treatment opportunities: In some patients with advanced cancer, when the recommended drugs in the guidelines are ineffective, NGS testing can explore the possibilities of other targeted drugs, and strive for new treatments and better prognosis for patients.

4. Promote the development of precision medicineNGS testing is an important part of precision medicine. Through NGS testing, doctors can understand the patient's genetic mutation status and thus develop more accurate treatment plans for patients. This individualized treatment method based on genetic mutation can not only improve the treatment effect, but also reduce medical costs and bring greater benefits to patients.

NGS second-generation sequencing has extensive application and far-reaching significance in clinical practice. It not only improves the accuracy of genetic diseases and prenatal diagnosis, but also provides strong support for the clinical diagnosis and treatment of tumors and promotes the development of precision medicine. With the continuous advancement of technology and the expansion of application scope, NGS testing will play a more important role in future clinical practice.
