Non-invasive blood tests for earlier diagnosis and treatment of endometriosis

Abstract

Endometriosis is a chronic condition characterized by the presence of endometrial-like tissue outside the uterus, leading to symptoms such as dysmenorrhea and chronic pain. It affects approximately 2–10 % of women of reproductive age and up to 50 % of those experiencing infertility, significantly impacting the healthcare system. Despite its prevalence, endometriosis presents in a variety of forms and phenotypes, partly due to the absence of a non-invasive biomarker for diagnosis. Early detection of endometriosis is crucial for effective management; however, the most dependable diagnostic method currently available is laparoscopy. Many women are reluctant to undergo this surgical procedure, resulting in a substantial number remaining unaware of their condition. This review aims to explore the potential of non-invasive blood tests in developing reliable biomarkers or a combination of biomarkers for the early detection and diagnosis of endometriosis. Innovative therapies such as immunomodulation, stem cell therapy, biosensors, and nanotheranostics present promising avenues for personalized diagnosis and treatment, focusing on genetic, epigenetic, and immunological aspects. The review emphasizes the importance of various biomarkers and the necessity for further research to enhance diagnosis and improve the quality of life for women affected by endometriosis.
