Lanzhou researchers develop gene chip for early diagnosis of colorectal cancer

, a scientific research unit of Lanzhou University National Science and Technology Park successfully developed a gene chip for early diagnosis of colorectal cancer, and carried out preliminary testing of 50 cases of fecal samples of those who were at risk, with a specificity, sensitivity and clinical accuracy rate of 95%Colorectal cancer is one of theof common malignanttumors, which has shown three new characteristics in recent years: "the incidence rate is rising, the age of onset is advanced, and the misdiagnosis rate is high"According to the research and development personnel, the chip through multi-gene composite detection method, can be minimally invasive painless, fast and easy detection of colorectal cancer genetic markers changes, not only to make up for the current immunological diagnostic products and PCR product detection sensitivity and specificity can not take into account the shortcomings, but also conducive to a wide range of screening, screening, so as to early detection of patientsAt present, the number of patients with colorectal cancer in the middle and late stagein in China is more than 90%It is reported that medical,disease
diagnosis gene chip as an advanced, large-scale, high-throughput detection technology, applied to the diagnosis ofdisease, with a high degree of sensitivity and accuracy, fast and simple, can detect a variety ofdiseasesand other advantagesAnd the small flux chip has the advantage of low cost, overcomes the current high cost of gene chip, is suitable for large-scale promotion and useAccording to the identification of the relevant expert group in Gansu Province, the result has a high novel, innovative and practical type, has a wide range of research prospects and good social and economic benefits, has reached the leading level of similar research in ChinaThe project is being undertaken by Lanzhou Baiyuan Gene Technology Co., Ltd., whose technical director, Che Lisaid, said the study is intended to be based on the development of early diagnosis of colorectal cancer gene chip and clinical sample small trials, next year to carry out a further 3000 clinical samples of large-scale clinical trials(Reporter Yin Chunyong)
