Do you feel intimidated when you are told that you need a gastroscopy? Inevitably, to this day, gastroscopy is still the best criterion for diagnosing gastric cancer. Although it may cause some discomfort, its importance for early detection and stomach cancer cannot be overlooked.
Health knowledge sharing: the importance of early screening of gastric cancer and common early screening methods.
Gastric cancer is one of the most common malignant tumors of the digestive tract in daily life, which mostly originates from gastric mucosal cells. Most gastric cancer patients have no obvious symptoms in the early stage, but gradually develop symptoms of indigestion, fullness and discomfort as the disease progresses, but because these symptoms are mild, they are often easily ignored by patients, and most of the symptoms have progressed to the middle and advanced stages when the symptoms are severe, and the risk of death will be increased once distant metastasis occurs.
Surgery is the main means of gastric cancer, and the 5-year survival rate of patients with early gastric cancer can reach about 90% after surgical resection of tumor tissue, while the prognostic survival rate of advanced gastric cancer is still low, even after comprehensive means, the 5-year survival rate is still low, so it is particularly important to make a clear diagnosis as soon as possible and target it. Although gastroscopy can diagnose diseases, it is invasive, and many people miss early screening and diagnosis and treatment because they resist gastroscopy, so the medical community has been actively looking for a simpler and safer screening method.
Popular Science Time: Liquid Biopsy Monitoring Methods and Advantages.
In recent years, liquid biopsy technology has become a new trend in early cancer screening. Liquid biopsy is to monitor the cells, circulating DNA, RNA and circulating exosomes of primary tumors or metastatic tumors in urine, cerebrospinal fluid and blood samples to achieve early, dynamic and low-invasive monitoring of tumors. Traditional tissue biopsy cannot dynamically monitor the development process of tumors, it is difficult to capture small lesions, and it is an invasive test, and patient compliance is not high. Liquid biopsy is a non-invasive test, simple to operate, reproducible, and can be repeated at different stages of the disease, which can detect the genetic information related to the primary tumor at different stages of tumor progression, so as to achieve early diagnosis, dynamic monitoring and prognosis ......It can be said that liquid biopsy is a very promising form of detection.
New Hope for the Industry: Clinical Application of Liquid Biopsy Technology and Product Implementation.
Based on multiple advantages, liquid biopsy technology has been widely used in the diagnosis and development of a variety of solid tumors in recent years, and related technical products have been implemented and put into clinical use. The GastroClear[GF]2122[GF](MF2122[GF]) developed by Mirxes, a liquid RNA biopsy company, is the world's first molecular diagnostic kit for serum gastric cancer. With only a small amount of blood drawn, the reagent can be tested within a few hours, and the detection sensitivity for stage I gastric cancer is as high as 875%。Gastroclear[GF]2122[GF](Seeking Xiaowei [GF]2122[GF]) is used for testing, and if the score exceeds the cut-off line, the subject is recommended to undergo further gastroscopy, otherwise the test is repeated every 2-3 years. With convenient sampling, fast results and high detection sensitivity, GastroClear[GF]2122[GF](Mixiaowei [GF]2122[GF]) is definitely an effective auxiliary screening method for gastric cancer, which is of great significance for the popularization of screening and risk stratification of high-risk groups of gastric cancer and the improvement of early diagnosis rate.
In fact, most primary cancer cells can be effectively controlled. For example, because early-stage cancer has not spread and metastasized, it is mostly possible to use a combination of local means such as surgery or radiotherapy. However, metastasis of cancer cells is the real risk. It is estimated that more than 90% of cancer deaths are caused by metastases. However, until now, the mechanism of cancer cell spread and metastasis is largely unknown, and it will take time for humans to overcome the problem of cancer.
This year's work report will open a new track of life sciences as a key task, indicating the support and attention to this field, and promoting the research and development and innovation of related technologies and products, which means that more policy and financial support will be provided in the field of early cancer screening in the future, so as to enhance the public's trust in early cancer screening technology, so as to promote its wider application. It is believed that in the future, the field of early cancer screening in China will be further developed, and at the same time, the supervision and standardization of medical technologies such as early cancer screening will be strengthened, so as to provide safer and more effective early screening tests for the general public.
