Sleep disorders and prostate cancer prognosis: biology, epidemiology, and association with cancer development risk

Visual analysis of the research frontiers, hotspots and trends of exercise therapy intervention in tumor-related sleep-wake disorders

Objective

To systematically understand the research frontiers, hotspots and development trends of exercise therapy in the intervention of tumor-related sleep-wake disorders, and to provide scientific basis for follow-up research.

Methods

Downloaded the original research papers on February 26, 2024, from the Web of Science core collection database, on tumor-associated sleep-wake disorders. The data that met the inclusion criteria were imported into the Bibliometric Analysis Platform (http://biblimetric.com), CiteSpace 6.3.R1 and VOSviwer1.6.20 software for visual analysis, and imported into Excel2021. Scientometric analysis was performed with Oringin2021 and PyCharm Community Edition 2022.1.3.

Results

A total of 512 original research papers on tumor-related sleep-wake disorders were obtained. The most influential countries in the subject area are the United States, Spain and German, the institutions are the University of California System, Sun Yat Sen University and Northwestern University, et al., the authors are Berger AM, Aaronson NK, Bower JE, et al., and the journals are Cancer, Brit J Cancer and Cancer Nurs. The co-cited references suggest that the current research frontier in the field mainly involves the level, place and program of exercise therapy, including the relationship between physical activity, sedentary behavior and cancer prevention and control. The results of co-occurrence keyword network analysis showed that quality of life, physical activity, breast cancer, exercise, fatigue, and survivors may be the research hotspots in this field, with breast cancer, health, aerobic exercise, adults, and chemotherapy being the most popular.

Conclusions

The number of papers published and the research enthusiasm in this field show a steady upward trend. However, there is a lack of influential institutions and scholars, and there is relatively little research collaboration across countries/regions/institutions. The scientific research influence of institutions and scholars in most European and American countries/regions is significantly ahead of that of institutions and scholars in Asian and African countries/regions. But Sun Yat Sen University in China is a relatively active and influential scientific research institution in recent years, which is worthy of attention. In addition, the research frontier of this discipline is the level, place and program of exercise therapy auxiliary intervention, and the research hotspots involve breast cancer, health, aerobic exercise, adults, chemotherapy, et al. Their clinical efficacy needs to be further demonstrated in multi-center, large-sample and high-quality prospective studies.

Insights into Aptamer-Drug Delivery Systems against Prostate Cancer

Prostate cancer is a common cancer in elderly males. Significant progress has been made in the drug therapies for prostate cancer in recent years. However, side effects are still problems that have not been overcome by the currently used anti-prostate cancer drugs. Novel technologies can be applied to reduce or even eliminate the side effects of drugs. An aptamer may be a sequence of nucleic acids or peptides that can specifically recognize proteins or cells. Taking advantage of this feature, scientists have designed aptamer-drug delivery systems for the development of anti-prostate cancer agents. Theoretically, these aptamer-drug delivery systems can specifically recognize prostate cancer cells and then induce cell death without attacking normal cells. We collected the relevant literature in this field and found that at least nine compounds have been prepared as aptamer-drug delivery systems to evaluate their precise anti-prostate cancer effects. However, the currently studied aptamer-drug delivery systems have not yet entered the market due to defects. Here, we analyze the published data, summarize the characteristics of these delivery systems, and propose ways to promote their application, thus promoting the development of the aptamer-drug delivery systems against prostate cancer.
