Examining the efficacy of treatments for arm lymphedema in breast cancer survivors: an overview of systematic reviews with meta-analyses.

Background: Lymphedema affects one in six breast cancer survivors making it a global healthcare challenge. There is considerable debate about the efficacy of different treatments for lymphedema. We aimed to summarize the current evidence for treatments for lymphedema in breast cancer survivors. Methods: In this overview of systematic reviews with meta-analyses (SRMAs), five databases were searched for SRMAs of randomised controlled trials (RCTs) reporting effects of medications, surgery, exercise, laser therapy, acupuncture, kinesio taping, or complex decongestive physiotherapy (CDP) for breast cancer-related lymphedema published from database inception up to March 7, 2023. Data extraction was performed for the SRMAs and RCTs, and SRMAs were appraised with AMSTAR2. Random effects meta-analyses of the RCTs provided estimates of the pooled effects sizes (Hedges' g) for each treatment modality. This study is registered with PROSPERO, CRD42020184813. Findings: 1569 studies were identified by the search and eighteen SRMAs with 51 RCTs were included, investigating manual lymphatic drainage (MLD), compression pump, exercise, kinesio taping, laser, and acupuncture. Overall, the methodological quality of the SRMAs was low. SRMAs reached different conclusions for all treatment modalities, except for kinesio taping where the two SRMAs found no effect. The analysis of 40 RCTs with 1970 participants revealed a small effect across all interventions compared to any control (g = 0.20, p = 0.047, I2 = 0.79), corresponding to volume reductions of 119.7 ml (95% CI 135-104) and 88.0 ml (95% CI 99-77) in the intervention and control groups, respectively, and a small effect of exercise (g = 0.26, p = 0.022, I2 = 0.44). The between-group differences in volume reduction were small and did not reach statistical significance for any one treatment modality. Interpretation: Based on the available data, there is no evidence of superiority of any one treatment on volume reduction nor any solid research refuting these treatments. Thus, definitive conclusions to inform clinical practice about the efficacy of these treatments cannot be drawn. Due to poor-quality evidence, more research is needed to untangle the efficacy of each treatment component for different stages of lymphedema. Funding: Danish Cancer Society.

Nighttime compression supports improved self-management of breast cancer-related lymphedema: A multicenter randomized controlled trial.

BACKGROUND: Lymphedema is a prevalent long-term effect of breast cancer treatment associated with reduced quality of life. This study examined the efficacy of nighttime compression as a self-management strategy for women with chronic breast cancer-related lymphedema. METHODS: Th authors conducted a parallel 3-arm, multicenter, randomized trial. Women were recruited from 3 centers in Canada and randomized to group 1 (daytime compression garment alone [standard care]), group 2 (daytime compression garment plus nighttime compression bandaging), or group 3 (daytime compression garment plus the use of a nighttime compression system garment). The primary outcome was the change in excess arm volume from the baseline to 12 weeks. Participants from all groups used a nighttime compression system garment from weeks 13 to 24. RESULTS: One hundred twenty women were enrolled, 118 completed the randomized trial, and 114 completed the 24-week follow-up. The rates of adherence to nighttime compression were 95% ± 15% and 96% ± 11% in the compression bandaging and nighttime compression system groups, respectively. After the intervention, the addition of nighttime compression was found to be superior to standard care for both absolute milliliter reductions (P = .006) and percentage reductions (P = .002) in excess arm lymphedema volume. Significant within-group changes were seen for quality of life across all groups; however, no between-group differences were found (P > .05). CONCLUSIONS: The trial demonstrated a significant improvement in arm lymphedema volume from the addition of nighttime compression whether through the application of compression bandaging or through the use of a nighttime compression system garment. LAY SUMMARY: Lymphedema is swelling that occurs in the arm on the side of the surgery for breast cancer. Lymphedema occurs in approximately 21% of women. Lymphedema tends to worsen over time and can result in recurrent infections in the arm, functional impairment, and pain. Currently, treatment consists of intensive treatments to reduce the swelling followed by regular use of a compression sleeve during the day. This study examined and found a benefit from the addition of nighttime compression (whether through self-applied compression bandaging or through the use of a nighttime compression system garment) to the use of a daytime compression sleeve.

Development of Sarcopenia in Patients With Bladder Cancer: A Systematic Review.

OBJECTIVE: Sarcopenia is known to influence cancer-related complications and overall survival. However, the effect of cancer treatment on the development or progression of sarcopenia is relatively unknown. The primary aim of this systematic review was to determine the prevalence and development of sarcopenia among people with bladder cancer. DATA SOURCES: A systematic search was performed in PubMed, Web of Science, and EMBASE. Studies with ≥2 assessments of sarcopenia were eligible for inclusion. Five retrospective cohorts were included with a total of 438 participants. The baseline prevalence of sarcopenia across studies varied from 25% to 69% and post-treatment prevalence from 50% to 81%. The average loss of muscle mass was 2.2% to 10% during a time course of 3 to 12 months. CONCLUSION: The prevalence of sarcopenia markedly increased during cancer treatment in patients with bladder cancer. Further research into the effect of different treatment regimens on the development of sarcopenia, and how these changes might affect functional capacity and survival is needed. IMPLICATIONS FOR NURSING PRACTICE: The development of sarcopenia is important to understand because of its negative affect on quality of life, complications, and mortality. Further, understanding how sarcopenia develops during treatment could potentially strengthen nurses' future care plans for patients with bladder cancer.

Shared concern with current breast cancer rehabilitation services: a focus group study of survivors' and professionals' experiences and preferences for rehabilitation care delivery.

OBJECTIVES: Breast cancer survivors experience a wide spectrum of physical sequelae from cancer treatment. National and international guidelines recommend that rehabilitation is offered from the point of diagnosis. However, there is a lack of data on the translation of these recommendations into clinical care. The objective of this study was to explore the experiences of breast cancer survivors, rehabilitation professionals and breast surgeons on current rehabilitation services including preferences for care delivery, specific ways to promote early detection and timely management of upper body issues and attitudes towards self-managed surveillance and rehabilitation. DESIGN: Qualitative focus groups. Breast cancer survivors completed a questionnaire about rehabilitation services received and experience of upper body issues. These quantitative data were collected to provide context for the qualitative data and increase transferability. Transcripts were analysed using content analysis. SETTING: Five geographically distinct health authorities in British Columbia, Canada. PARTICIPANTS: Eleven focus groups were conducted with 35 breast cancer survivors, 29 rehabilitation professionals and 5 breast surgeons. RESULTS: Three categories captured participants' concern and wish for improved care: (1) cut the cancer out and goodbye; (2) you have to look out for yourself and (3) in a perfect world. All breast cancer survivors reported chronic upper body issues (mean 4.5 unique issues). Breast cancer survivors expressed worry and uncertainty in their solo management of the rehabilitation. The current services were reported to not enable early detection and timely management. Suggestions included reorganising the timing of patient education and improving the quality of and access to rehabilitation services by elevating the knowledge among healthcare professionals and providing multimodal self-management resources. CONCLUSIONS: The results revealed a gap between oncology guidelines and the current clinical reality. The rehabilitation services were reported in need of revamping to increase equity of care. Multiple upper body issues were reported by many breast cancer survivors.
