Physical Exercise and Quality of Life of Patients Diagnosed with Colorectal Cancer: Systematic Literature Review

Global status of research on gastrointestinal cancer patients' quality of life: A bibliometric and visual analysis from 2003 to 2023

Objective

To analyze the current research status, hotspots, and frontiers in the field of Gastrointestinal (GI) cancer and quality of life (QoL) through the bibliometrics method, and to provide references and guidance for future research.

Methods

Literature related to GI cancer and QoL from April 1, 2003 to March 31, 2023 was retrieved from the Web of Science Core Collection database. CiteSpace 6.2.R1 was performed for collaboration analysis, keyword co-occurrence analysis, and document co-citation analysis.

Results

A total of 1224 publications were included in this study. There has been a significant increase in the number of publications in this field over the past two decades. The United States, the Karolinska Institute and the University of Amsterdam, and Pernilla Lagergren are the most prolific country, institution, and author, respectively. The links between most of the research constituents were relatively thin (centrality <0.1). The keyword analysis indicates that the benefits of physical activity on QoL, the levels of psychological distress and its relationship with QoL, as well as the development and validation of QoL measurement tools have been the research hotspots. Open-label/double-blind trials exploring therapeutic interventions and more targeted new drugs or more effective drug combinations, and longitudinal studies determining the direction of the association between psychological distress and QoL at different time points, may be emerging trends in this field.

Conclusion

The cooperation among countries, institutions, and authors in this field should be strengthened. In addition, the health benefits of light physical activity, interventions for QoL, trajectory and direction of the relationship between psychological distress and QoL may be the focus of future research.

Remote and Unsupervised Exercise Strategies for Improving the Physical Activity of Colorectal Cancer Patients: A Meta-Analysis

Colorectal cancer (CRC) burden across the world is expected to increase by ~2.2 million new cases and ~1.1 million deaths by 2030. Regular physical exercise is recommended to prevent CRC, but the myriad of protocols preclude further discussion on how to manage its variables for this population. Home-based exercise guided by remote monitoring provides an alternative to surpass the barriers of supervised exercise. However, no meta-analysis was conducted to verify the effectiveness of this intervention for improving physical activity (PA). We performed a systematic review of remote and unsupervised strategies imposed on CRC patients for improving PA and compared, via a meta-analysis, their effectiveness against CRC patients submitted to usual care or no intervention. The databases PubMed, Scopus, and Web of Science were searched on 20 September 2022. Eleven studies attained the criteria for eligibility in the qualitative approach, and seven were included in the meta-analysis. No significant effect (p = 0.06) of remote and unsupervised exercise intervention was observed. However, a sensitivity analysis including three studies that only considered CRC patients was performed, demonstrating a significant effect in favor of exercise (p = 0.008). Based on our sensitivity analysis, remote and unsupervised exercise strategies were effective to improve the PA of CRC patients.
