[Fluorescence imaging technique: diagnostic and therapeutic interest in gynecology].
Fluorescence techniques are presently used by several medical and surgical disciplines (dermatology, pneumology, urology, gastrointestinal surgery) for the diagnosis of pre-cancerous and cancerous lesions. The technique is based on the application of 5-aminolevulinic acid (5-ALA) which induces the production of an endogen photosensitizer: protoporphyrin IX (PpIX). Fluorescence detection of the infraclinical dysplasia lesion is based on the contrast between fluorescent pathological tissue and non-fluorescent healthy tissue. Moreover, there is a correlation between the degree of tissue dysplasia and fluorescence intensity. Fluorescence imaging could allow easier detection of infraclinical lesions enabling more well-targeted treatment. In gynecology, many experimental and clinical studies have been conducted on the detection and treatment of cervical dysplasia and the diagnosis and treatment of vaginal and vulvar diseases as well as the diagnosis of peritoneal micrometastasis from ovarian cancer, the diagnosis and treatment of endometrial alterations, and the treatment of locoregional recurrent skin breast cancer. The aim of this work is to present the fundamental principles of fluorescence imaging technical and to expose the diagnostic and therapeutic prospects in gynecology.
