Sexual health is an important determinant of the overall health of a population, as addressed in the French National Strategy 2017-2030. For a long time neglected in oncology, sexual health is now part of clinical assessments in cancer support care and is fully integrated into practice recommendations. However, existing evidences, though limited, are still suggesting unmet needs during the palliative phase of the disease. Current literature focuses on the assessment and management of potential issues related to genital cancers - primarily gynecological, breast, and prostate cancers - but also on post-cancer experiences. The sexual health needs of patients in palliative care are understudied, except one study that reports how patients are considering sexuality as an important aspect of their lives, even during the last weeks to days of life. In the aim of developing an efficient complex intervention for the population of patients with cancer in palliative situations, it is necessary to identify the needs, facilitators, and modalities required for promoting sexual health in this population (beyond the extensively studied cases of genital cancers). A solely patient-centred approach would be limiting, and this objective requires an approach dedicated to the life partners as well. To assess satisfaction related to sexual health and gain insights regarding the expectations of patients and their partners towards the healthcare system, the study INTIMI-K will utilize a mixed methodology involving the use of a questionnaire, including validated scales, and semi-structured interviews. Patients aged 18 and older, diagnosed with advanced solid or hematological cancers, along with their life partner will be included.
