Abstract:

Objective To conduct a scoping review of studies on the use of virtual reality（VR） in cancer-related cognitive impairment（CRCI），and to generalize and summarize the current state of the art of VR use in CRCI. Methods The computerized retrieval of PubMed，Embase，Web of Science，the Cochrane Library，WanFang Data，CNKI and VIP databases was carried out. Studies were collected from the database establishment to July 2023. 3 researchers independently screened the literature，extracted data，and evaluated the risk of bias in the included studies. Results A total of 9 studies were included. VR was used for CRCI assessment and intervention. The assessment included visual and auditory memory，executive function and verbal fluency. The intervention content involved common cognitive impairment dimensions of CRCI，including memory，executive ability，attention，information processing speed and language fluency. The intervention frequency ranged from 3 to 5 times/week，15 to 60 min/time，and the duration was 2 to 8 weeks. The intervention frequency and intensity were dynamically adjusted based on the patient performance，game type and complexity. VR has shown good validity and benefits in CRCI assessments and interventions，while improving patients’ sleep quality and ability to perform daily living，with higher patient acceptance and no VR related adverse events being reported，but its role in improving mental health remains controversial. Conclusion VR shows good validity and benefits in CRCI assessment and intervention，and has good safety and high acceptance. In the future，it is still necessary to conduct large-sample，randomized controlled studies，attach importance to the role of patient needs in the formulation of VR cognitive intervention programs，and increase CRCI-related objective indicators to further verify the effect of VR intervention on CRCI. At the same time，longitudinal evaluation and follow-up programs may be considered to determine progressive changes in CRCI from VR interventions
