Cognitive complaints in patients after cancer treatment: understanding oncologists' representations and management...

Cognitive disorders related to cancer treatment, although common, remain under-recognized in clinical practice. Their assessment is hampered by a lack of standardized protocols, solid evidence and adapted resources. This study aims to explore the knowledge, perceptions and practices of oncologists concerning these disorders, from a patient quality of life perspective. A qualitative community-based research study was carried out with 20 oncologists practicing in France, recruited electronically. Semi-structured interviews explored four dimensions: caregiver-patient communication, information transmission, perceptions of cognitive impairment, and management strategies. A reflective thematic analysis was carried out, with the participation of patient-researchers. Oncologists recognize the existence of cognitive disorders as a possible side effect of treatment, but perceive them as multifactorial and often trivialized. These disorders are rarely discussed spontaneously, in the absence of an explicit complaint from the patient. Reported obstacles include a lack of training, a heavy workload, a shortage of specialized resources and diagnostic uncertainties. Interdisciplinary coordination remains limited. Post-treatment cognitive disorders represent a grey area in oncology practice. Their recognition and management require better training for professionals, systematic integration into quality-of-life assessments, and the development of structured care networks. It is recommended to create simple clinical tools, improve access to specialists, and raise awareness within healthcare teams. A patient-centered, multidisciplinary approach is essential to meet these challenges, which have yet to be fully addressed.
