KCNQ1OT1, A NEW BIOMARKER IN PERIPHERAL BLOOD FOR NON-INVASIVE DETECTION OF GASTRIC CANCER (GC)

摘要

The invention relates to a non-invasive method for detecting gastric cancer based on the detection of a new molecular marker in blood. In particular, via the detection of the long non-coding RNA (LncRNA) KCNQ1OT1 in peripheral blood, wherein an increase in the expression of this LncRNA correlates with gastric cancer or the precursor lesions thereof (OLGA stage III and IV).
