Effectiveness of internet-based support interventions on patients with breast cancer: a systematic review and narrative synthesis

Abstract

ObjectiveTo identify the elements of internet-based support interventions and assess their effectiveness at reducing psychological distress, anxiety and/or depression, physical variables (prevalence, severity and distress from physical symptoms) and improving quality of life, social support and self-efficacy among patients with breast cancer.DesignSystematic review and narrative synthesis.Data sourcesWeb of Science, Cochrane Library, PubMed, MEDLINE, PsycINFO, CINAHL, CNKI, Wanfang and VIP from over the past 5 years of each database to June 2021.Eligibility criteria for study selectionIncluded were randomised controlled trials (RCTs) or quasi-experimental (QE) studies focusing on internet-based support interventions in patients with breast cancer.Data extraction and synthesisReviewers independently screened, extracted data and assessed risk of bias (Cochrane Collaboration’ risk of bias tool, Joanna Briggs Institute reviewer’s manual). Narrative synthesis included the effect and elements of internet-based support interventions for women with breast cancer.ResultsOut of 2842 articles, 136 qualified articles were preliminarily identified. After further reading the full text, 35 references were included, including 30 RCTs and five QE studies. Internet-based support interventions have demonstrated positive effects on women’s quality of life and physical variables, but inconsistent effectiveness has been found on psychological distress, symptoms of anxiety and/or depression, social support and self-efficacy.ConclusionsInternet-based support interventions are increasingly being used as clinically promising interventions to promote the health outcomes of patients with breast cancer. Future research needs to implement more rigorous experimental design and include sufficient sample size to clarify the effectiveness of this internet-based intervention.PROSPERO registration numberCRD42021271380.

The efficacy of mindfulness-based stress reduction vs. standard or usual care in patients with breast cancer: a systematic review and meta-analysis of randomized controlled trials

“…Breast cancer is the most common malignant tumor with the highest incidence in women ( 1 , 2 ), and both the incidence and mortality of breast cancer have shown a gradual upward trend. Due to the disease itself or the adverse effects of cancer treatment, breast cancer patients are prone to negative emotions such as anxiety, depression, and stress, which seriously affect their quality of life (QOL), even lead to further deterioration and recurrence of the disease, increase the mortality of breast cancer, and seriously affect the prognosis ( 3 , 4 ). Therefore, improving the mental health of breast cancer patients is essential for improving the survival rate and QOL of patients ( 5 ).…”

Managing chronic pain after breast cancer treatments: are web-based interventions the future?

“…This current and previous reviews [35,37] suggest that digital interventions promoting symptom monitoring and support patients to self-manage symptoms have been shown to improve outcomes in cancer patients. Additionally, these interventions can facilitate early detection and intervention by promoting regular monitoring via self-assessment tools and symptom tracking.…”

“…There is a plethora of studies exploring options for managing chronic symptoms and follow-up in breast cancer, some which are generic and others aimed specifically at established pain. The majority of studies included in a recent review [37] targeted quality of life, anxiety and depression, psychological distress, physical variables, social support or self-efficacy. None had the specific aim of supporting pain as a primary outcome.…”

The Role of Social Media in Breast Cancer Care and Survivorship: A Narrative Review

“…In recent years, the utilisation of the Internet and social media in the healthcare industry has seen significant growth, and it has the potential to be an invaluable resource in the context of BC care and survivorship [14–17]. The Internet provides a means of addressing some of the difficulties faced by individuals living with and after BC, by facilitating access to health information and by connecting them to support resources and interventions [18–20]. At the same time, this enables them to become part of an ever-growing community beyond geographical borders and access restrictions.…”
