Int J Gynaecol Obstet. 2013 Apr;121(1):35-40. doi: 10.1016/j.ijgo.2012.10.025. van den Berg, Liseth L| Crane, Lucia M A| van Oosten, Marleen| van Dam, Gooitzen M| Simons, Arnold H M| Hofker, H Sijbrand| Bart, Joost Department of Pathology and Medical Biology, University of Groningen, University Medical Center Groningen, Groningen, the Netherlands. OBJECTIVE: To evaluate the expression of biomarkers in endometriotic tissue in order to determine the most promising molecules for targeted intraoperative imaging. METHODS: Tissue samples were obtained from 18 patients with endometriosis. The intensity and pattern of expression of the following biomarkers were assessed by immunohistochemistry: C-X-C chemokine receptor type 4 (CXCR4), epithelial cell adhesion molecule (EpCAM), estrogen receptor (ER), folate receptor alpha (FR-alpha), hypoxia-inducible factor 1-alpha (HIF-1alpha), progesterone receptor (PR), and vascular endothelial growth factor A (VEGF-A). The Target Selection Criteria scoring system was used to select the most promising biomarkers for intraoperative imaging. RESULTS: Expression of CXCR4, EpCAM, ER, PR, and VEGF-A was scored as strong in endometriotic epithelium. Expression of FR-alpha was detected in 94.4% of samples, whereas HIF-1alpha was expressed in just 5.6% of samples. Of note, CXCR4, ER, and VEGF-A were also expressed in surrounding healthy tissue, thus reducing the target-to-background ratio. CONCLUSION: Of the 7 biomarkers assessed in the present study, EpCAM, FR-alpha, and VEGF-A seem the most promising for targeted intraoperative imaging of endometriosis.
