Global research on cancer and sleep: A bibliometric and visual analysis of the last two decades.

This study systematically analyzed the hotspots and frontiers in the field of cancer and sleep and called for strengthening cooperation among countries, institutions, and authors. In addition, intervention measures for the cancer symptom cluster, the bioavailability of exogenous melatonin, the causal relationship between OSA and cancer, the mechanism of tumor-induced sleep disruption, the dose-response relationship between sleep duration and cancer risk, and the path relationship between sleep quality influencing factors may be the focus of future research.
