Determination of the Feasibility of Tumoural Somatic Mutations Detection in Blood of Patients With Ovarian Cancer

BOVARY-Pilot is a monocentric prospective transversal pilot study with a total duration of 6 months. The purpose of this study is to determine the feasibility of detecting somatic tumor mutations in the blood of patients with ovarian cancer in order to determine whether a blood test can replace a tissue biopsy to prescribe a personalized treatment. The method will consist of a single blood sample during the patient's visit and prior to the establishment of any newly diagnosed cancer treatment. The concordance of somatic mutations (SNV) found in tissue and in cell-free DNA (cfDNA) extracted from blood will then be compared
