This project proposes a structuring of supportive oncology care for the recovery phase after gynecological cancer (ovarian/trope/peritoneum or endometrium). Patients will be divided into three groups based on the identification of oncological support care needs. Patients with supportive oncology care needs will be randomized into two groups: the experimental group, receiving a personalized post-cancer plan with a multidisciplinary assessment of supportive oncology care needs in a day hospital and coordinated follow-up by the referring study nurse, and the control group, receiving a personalized post-cancer plan without a day hospital. Randomization will be stratified according to tumor location (ovary vs. endometrium), use of supportive oncology care during treatment, and treatment center. Patients with no need for supportive oncology care will be followed in an observational cohort. The main objective is to identify and manage the supportive oncology care needs of patients in remission from endometrial or ovarian cancer to improve their quality of life and post-treatment follow-up. A medico-economic analysis will be performed.
