Markers, primers, probes and kit for early screening and diagnosis of endometrial cancer

Abstract

The present invention discloses markers, primers, probes and a kit for early screening and diagnosis of endometrial cancer. The markers are partial methylated regions in the four genes of CDO1, CELF4, HAND2 and HS3ST2. Detection primers and probes are designed for these methylated regions and to have clasp structures. The kit includes the aforementioned primers and probes. The present invention screens and combines multiple methylated regions to determine the most suitable methylated position for combined diagnosis, which can significantly improve the sensitivity and specificity of the detection for early endometrial cancer. The kit is especially suitable for early screening and diagnosis of endometrial cancer with cervical exfoliated cells as a sample. Even if the DNA template concentration is low, endometrial cancer can be detected. The kit has the advantages of non-invasive sampling, fast detection speed, higher sensitivity and specificity, etc., and can ensure the accuracy of the results to help achieve the purpose of early detection, early diagnosis, and early treatment of endometrial cancer.
