New Blood Test Revolutionizes Early Detection of Stomach Cancer: JAMA Surgery Study Confirms Efficacy of DEX-G2
A groundbreaking multicenter study, published on July 30, 2025, in JAMA Surgery, confirms the outstanding diagnostic performance of the Destinex assay, the basis for Cizzle Bio's DEX-G2 blood test for the early detection of stomach cancer – one of the deadliest cancers worldwide. The study shows that the minimally invasive DEX-G2 test detects stomach cancer in early, treatable stages with high accuracy, significantly improving chances of cure. The DESTINEX study, conducted at leading cancer centers in Japan and South Korea, examined 809 serum samples from 480 participants, including stomach cancer patients and control groups. Using machine learning, the test demonstrated exceptional precision in detecting early-stage stomach cancer (pT1) with a sensitivity of 95.0% and an area under the curve (AUC) of 96.8%. The test is based on a specific combination of microRNAs from exosomes and cell-free serum, underscoring its high specificity and tumor reliability. A significant decrease in biomarkers…
