Immunohistochemical Analysis of Somatostatin Receptors in Endometriosis Tissue Samples: A Retrospective Study

Three types of endometriosis are described: superficial peritoneal endometriosis (SPE), ovarian endometrioma (OMA), and deep infiltrating endometriosis (DIE). The expression of somatostatin receptors (SSTR1, 2, and 5) in human endometrial tissue and its ectopic form has been previously studied and may be different in each type of endometriosis. The aim of this study was to assess the immunohistochemical expression of SSTR1, 2, and 5 in tissue samples of SPE, OMA, and DIE. We performed a retrospective analysis in the pathology department database. Patients aged 50% of the cells showed immunostaining. Seventy-six patients were included in the analysis. SSTR1 and 5 were expressed in 95.4% and 77.2% of SPE, respectively, in 95.8% and 83.3% of OMA, respectively, and in 100% and 80% of DIE, respectively. There was no significant difference between SPE, OMA, and DIE with regard to the SSTR1 (P=0.5) and SSTR5 (P=0.9) expression. We observed a significant difference between SPE (9.0%), OMA (16.6%), and DIE (63.3%) with regard to SSTR2 expression (P
