Effects of mindfulness-based interventions on quality of life of women with breast cancer: a systematic review

Effectiveness of eHealth mindfulness-based interventions on cancer-related symptoms among cancer patients and survivors: A systematic review and meta-analysis

OBJECTIVES

This review aimed to synthesize the best available evidence concerning the effectiveness of electronic health, mindfulness-based interventions (eHealth-MBIs) on anxiety, depression, mindfulness and quality of life (QoL) among cancer patients/survivors.

METHODS

Published and unpublished studies were retrieved from 10 electronic databases. Two independent authors screened and selected articles, extracted data using a standardized form and appraised the studies with the Cochrane risk of bias assessment tool. Meta-analyses were performed using a random-effect model with Review Manager (REVMAN). Standardized mean differences (SMDs) were used to determine intervention effects. Narrative syntheses were conducted for studies not suitable for meta-analyses. Heterogeneity was identified through I2 and chi-square statistics. Subgroup analyses were performed based on types of controls, age groups and gender. The Grading of Recommendations Assessment, Development and Evaluation approach was used to assess overall quality.

RESULTS

In total, 18 studies were included. The eHealth-MBIs improved primary outcomes of anxiety (SMD = -0.28) and depression (SMD = -0.24), among cancer patients/survivors with small effect sizes. Effects for the secondary outcomes of QoL (SMD = 0.25) and mindfulness (SMD = 0.29) were observed at short-term follow-up assessments but not at post-intervention. Overall quality was rated as low for the primary and very low for the secondary outcomes.

CONCLUSION

The eHealth-MBIs can be offered as a cost-effective and accessible alternative for cancer patients and survivors in healthcare settings. Future research may further explore the effectiveness of eHealth-MBIs based on different types of MBIs, cancer types, modes of delivery and other outcomes such as stress and post-traumatic growth.

Breast Cancer: A Lifestyle Medicine Approach

Breast cancer is the most common female cancer diagnosis in the United States (excluding skin cancers), and the second leading cause of female cancer death. This article highlights the role that lifestyle plays in primary breast cancer prevention, breast cancer treatment, and tertiary breast cancer prevention. Current data regarding the benefits of a predominantly plant-based diet in combination with physical activity and maintenance of a healthy body weight will be reviewed. The evidenced-based patient-focused recommendations developed by the World Cancer Research Fund/American Institute for Cancer Research will be discussed in the context of an overall lifestyle strategy. It is our hope that this publication empowers clinicians to provide patients with personalized cancer-protective lifestyle prescriptions.

Do Cochrane reviews reflect the latest evidence on meditation and mindfulness-based interventions? A snapshot of the current evidence

Growing evidence emphasizes the importance of meditation and mindfulness-based interventions (MBIs) in clinical settings. Here, we attempted to determine the clinical issues targeted by Cochrane reviews of meditation and MBIs and whether the judgements about quality/certainty as expressed by the Cochrane authors differed from that of non-Cochrane reviews and guidelines. The search database was the Cochrane Database of Systematic Reviews and the search date was December 31, 2019. Screening and selection of reviews was carried out by two independent authors. Overall, 20 reviews and four protocols were selected for this study. The effects of meditation and/or MBIs on various conditions described in the Cochrane reviews seemed ambiguous, with the exception of mindfulness-based stress reduction in breast cancer patients. However, we found some international clinical practice guidelines and latest non-Cochrane reviews describing meditation and MBIs to be more comprehensive and favorable. This gap is likely due to the priority-setting issues, which resulted in a lack of latest up-to-date evidence, as well as gaps in interventions of interest between Cochrane and non-Cochrane reviews.
