Gastric juice microRNAs as potential biomarkers for screening gastric cancer: a systematic review
BACKGROUND/AIM:
To date, the combination of gastroscopy with biopsy remains the only test validated for screening gastric cancer (GC). Currently, analysis of circulating microRNAs (miRNAs or miRs) is providing interesting information on GC prognosis, but since these molecules are shared by several types of cancer, its clinical use could be questionable and difficult. MicroRNAs in gastric juice (GJ) could represent a cogent alternative to screening GC by biopsy.
