2. HAVE ANY BIOMARKERS PROVED TO BE USEFUL DIAGNOSTIC TOOLS?
Any biomarker proven to reliably identify endometriosis would be a boon to medicine, as it would provide a noninvasive or minimally invasive alternative to diagnostic laparoscopy, the current gold standard. Regrettably, the search for such a biomarker has produced “disappointing results,” says Dr. Giudice.
“Recent systematic reviews of all proposed endometriosis-related biomarkers over the past 25 years in serum, plasma, urine, and endometrium could not identify an unequivocally clinically useful biomarker or panel of biomarkers,” she notes.7,8 “This is due mainly to low numbers of subjects, small populations for validations, cycle/hormonal- and disease stage–dependence, poorly defined controls, and low sensitivity and specificity.”
One hopeful development: “Whole genome transcriptomics of archived endometrial tissue and machine learning found several classifiers to diagnose and stage endometriosis with high accuracy that were validated on an independent sample set,” says Dr. Giudice.9 “However, these data now warrant a prospective, multisite study for further validation.”
