Do Compression Sleeves Reduce the Incidence of Arm Lymphedema and Improve Quality of Life? Two-Year Results from a Prospective Randomized Trial in Breast Cancer Survivors

Behavior change theory and behavior change technique use in cancer rehabilitation interventions: a secondary analysis

BACKGROUND

There is limited evidence depicting ways that behavioral theory and techniques have been incorporated into cancer rehabilitation interventions. Examining their use within cancer rehabilitation interventions may provide insight into the active ingredients that can maximize patient engagement and intervention effectiveness.

AIM

This secondary analysis aimed to describe the use of behavior change theory and behavior change techniques (BCTs) in two previously conducted systematic reviews of cancer rehabilitation interventions.

DESIGN

Secondary analysis of randomized controlled trials (RCTs) drawn from two systematic reviews examining the effect of cancer rehabilitation interventions on function and disability.

SETTING

In-person and remotely delivered rehabilitation interventions.

POPULATION

Adult cancer survivors.

METHODS

Data extraction included: behavior change theory use, functional outcome data, and BCTs using the Behavior Change Technique Taxonomy (BCTTv1). Based on their effects on function, interventions were categorized as "very", "quite" or "non-promising". To assess the relative effectiveness of coded BCTs, a BCT promise ratio was calculated (the ratio of promising to non-promising interventions that included the BCT).

RESULTS

Of 180 eligible RCTs, 25 (14%) reported using a behavior change theory. Fifty-four (58%) of the 93 BCTs were used in least one intervention (range 0-29). Interventions reporting theory use utilized more BCTs (median=7) compared to those with no theory (median=3.5; U=2827.00, P=0.001). The number of BCTs did not differ between the very, quite, and non-promising intervention groups (H(2)=0.24, P=0.85). 20 BCTs were considered promising (promise ratio >2) with goal setting, graded tasks, and social support (unspecified) having the highest promise ratios.

CONCLUSIONS

While there was a wide range of BCTs utilized, they were rarely based on theoretically-proposed pathways and the number of BCTs reported was not related to intervention effectiveness.

CLINICAL REHABILITATION IMPACT

Clinicians should consider basing new interventions upon a relevant behavior change theory. Intentionally incorporating the BCTs of goal setting, graded tasks, and social support may improve intervention efficacy.

Efficacy, safety of and adherence to adjustable compression wraps in the control phase of breast cancer-related lymphedema: A randomized controlled trial

OBJECTIVE

To evaluate efficacy, safety, and adherence to using adjustable compression wraps (ACWs) for upper limb volume control in women with breast cancer-related lymphedema.

DESIGN AND SETTING

Randomized controlled trial at a reference hospital for breast cancer treatment in Brazil.

PARTICIPANTS

Women in control phase of the breast cancer-related lymphedema.

INTERVENTIONS

Compared use of ACWs versus compressive mesh.

MAIN MEASURES

Evaluated before treatment, at 30 days, and 6 months after initiating therapy. The primary outcome was the change in excess limb volume. Secondary outcomes included adherence, incidence of adverse events, functionality, quality of life, and hand grip. Statistical analysis involved calculating the effect size (ES) with a 95% confidence interval.

RESULTS

Were included 71 women with mean excess limb volume of 321.79 mL (±194.98). In the 30-day analysis (Time 1), a reduction of 37.6 mL in volume was observed only in the ACW group (p = .041, ES 0.20), with improved functionality (p = .013, ES 0.22). In the six months analysis (Time 2), the compressive mesh group increased by 2.48% in volume (p = .023, ES 0.26) and demonstrated improvement functionality (p = .036, ES 0.27). Mild adverse events and satisfactory adherence were observed. However, in the intergroup comparison, no statistically significant difference was observed for any evaluated outcome-excess volume, incidence of adverse events, adherence, hand grip, quality of life, and functionality between the groups (p > .05) at both times.

CONCLUSIONS

Both compression therapies achieved satisfactory adherence, were safe, effective and equivalent for controlling limb volume in breast cancer-related lymphedema.

The effect of compression therapies and therapeutic modalities on lymphedema secondary to cancer: a rapid review and evidence map

The identification of effective therapeutic modalities to manage lymphedema secondary to cancer is a high priority among patients and clinicians. Complex decongestive therapy (CDT) remains a fundamental intervention for individuals with lymphedema; however, interventions involving modalities such as low level laser therapy, specially designed compression systems, and compression pumps may be helpful to improve outcomes and reduce costs of care. We conducted a rapid review of the literature examining compression therapies and therapeutic modalities in the treatment of lymphedema secondary to cancer. A search of the electronic databases from June 2018 to October 2023 was performed including MEDLINE, EMBASE, and CINAHL. The electronic search yielded 438 potentially relevant citations with 40 randomized controlled trials included in the review, and 30 in the mapping process. Ninety-three percent (n = 37) of the trials included participants with a diagnosis of breast cancer. Across all categories and domains, all but two trials were rated as having 'some concerns' or a 'high risk of bias'. Intervention effects ranged from clinically insignificant to large effects on lymphedema volume. Evidence mapping suggests potential for benefit from (1) compression garments for the prevention of lymphedema, (2) interventions added to CDT in the intensive reduction phase, and (3) nighttime compression and compression pump treatments in the maintenance phase. A multi-centre collaborative research approach is needed to support the conduct of high-quality large-scale trials to inform the optimal type, timing, and combination of compression therapies and therapeutic modalities in the treatment of lymphedema secondary to cancer.

New insights in breast cancer-related lymphedema

Upper limb lymphedema after breast cancer treatment including axillary dissection occurs in almost 20% of women. Its treatment consists of complete decongestive physiotherapy based on low-stretch bandage to reduce volume, followed by elastic compression to maintain it. In this article, we will detail recent data on lymphedema risk factors with possible genetic predisposition, prevention (surgical, compression), manual lymphatic drainage, physical activity, weight, advice, and treatments including gene therapy.

Beyond cancer treatment: dermo-aesthetic and other wellness recommendations for breast cancer patients

Breast cancer, a prevalent malignancy among women, has various physical and psychological impacts. This comprehensive review offers an in-depth look at multidisciplinary dermo-aesthetic intervention approaches, emphasizing the balance between oncological therapies and the management of these effects. The information presented spans specialties such as aesthetic medicine, plastic surgery, dermatology, physiotherapy, nutrition, odontology, and gynecology. This review, which serves as a clinical guide, aims to establish a safe protocol for non-medical interventions involving oncologists, physicians, and specialists from various areas in patients with breast cancer focused on improving their quality of life. This work offers personalized and integrative care strategies for the eradication of cancer. However, it is still necessary for patients to consult with their oncologist before undergoing any dermo aesthetic treatment. However, it is still necessary for patients to consult with their oncologist before undergoing any dermo aesthetic treatment.

Recent Advances in Therapeutic Modalities Against Breast Cancer-Related Lymphedema: Future Epigenetic Landscape

Background: Lymphedema is a significant postsurgical complication observed in the majority of breast cancer patients. These multifactorial etiopathogenesis have a significant role in the development of novel diagnostic/prognostic biomarkers and the development of novel therapies. This review aims to ascertain the epigenetic alterations that lead to breast cancer-related lymphedema (BCRL), multiple pathobiological events, and the underlying genetic predisposing factors, signaling cascades pertinent to the lapses in effective prognosis/diagnosis, and finally to develop a suitable therapeutic regimen. Methods and Results: We have performed a literature search in public databases such as PubMed, Medline, Google Scholar, National Library of Medicine and screened several published reports. Search words such as epigenetics to induce BCRL, prognosis/diagnosis, primary lymphedema, secondary lymphedema, genetic predisposing factors for BRCL, conventional therapies, and surgery were used in these databases. This review described several epigenetic-based predisposing factors and the pathophysiological consequences of BCRL, which affect the overall quality of life, and the interplay of these events could foster the progression of lymphedema in breast cancer survivors. Prognosis/diagnostic and therapy lapses for treating BCRL are highly challenging due to genetic and anatomical variations, alteration in the lymphatic vessel contractions, and variable expression of several factors such as vascular endothelial growth factor (VEGF)-E and vascular endothelial growth factor receptor (VEGFR) in breast cancer survivors. Conclusion: We compared the efficacy of various conventional therapies for treating BCRL as a multidisciplinary approach. Further substantial research is required to decipher underlying signaling epigenetic pathways to develop chromatin-modifying therapies pertinent to the multiple etiopathogenesis to explore the correlation between the disease pathophysiology and novel therapeutic modalities to treat BCRL.

The Effect of Manual Lymph Drainage and Compression Bandaging for Stage 2 Breast Cancer-Related Lymphedema: A Randomized Controlled Trial

Aim: To explore the effect of manual lymph drainage (MLD), compression bandaging (CB), or combined decongestive therapy (CDT), including MLD and CB, on stage 2 breast cancer-related lymphedema (BCRL). Methods: Sixty women with stage 2 BCRL were enrolled. They were randomly divided into the MLD group, the CB group or the CDT group. Each group, respectively, received MLD alone, CB alone, or CDT composed of MLD and CB, for 2 weeks. The volume and the local tissue water (LTW) of affected arms were measured before and after treatment. Arm circumferences were measured at 4 cm interval starting from the wrist to the shoulder with a tape measure. LTW was detected using the (tissue dielectric constant, TDC) method and was expressed as TDC value in two sites on the ventral midpoint of upper arm and forearm. Results: The volume of affected arms in each group after 2-weeks' treatment was lower than their baseline and the difference was statistically significant (p < 0.05). But there was no significant difference in volume change among three groups. The TDC value of the upper arm and forearm in the group CB and the group CDT decreased distinctly compared with baseline (p < 0.05). But the TDC value of the upper arm and forearm after MLD did not change (p > 0.05). Compared with the group MLD and the group CDT, the reduction of the TDC value in the group CB was more significant (p < 0.05). Conclusions: MLD or CB alone could effectively reduce the volume of affected arms for patients with stage 2 BCRL, and CB also could reduce the LTW more significantly. CDT did not seem to show an extra advantage. Therefore, CB may be the first choice for stage 2 BCRL. But for patients who are unwilling or intolerant to CB, MLD can be selected.

Complex physical therapy employing self-adjusting garment (ReadyWrap®) in breast cancer-related lymphedema cases in Brazilian women: a protocol for a randomized controlled trial

BACKGROUND

Lymphedema is a common complication following breast cancer treatment. The aim of this study is to evaluate the effectiveness of a self-adjusting compression garment (ReadyWrap®) in reducing (phase 1) and maintaining (phase 2) upper limb volume in women presenting breast cancer-related lymphedema.

METHODS

This study will comprise a randomized, controlled, single-blind clinical trial concerning women with breast cancer-related lymphedema undergoing treatment at a public cancer treatment reference hospital in the city of Rio de Janeiro, Brazil. The intervention will be carried out by adapting self-dressing versus the standard treatment of compressive bandaging (phase 1) and compressive mesh (phase 2). Both groups will be assessed at the beginning and end of intensive treatment and followed up for up to 12 months to evaluate immediate and late outcomes. Assessments will be carried out by physical upper limb examination (inspection, palpation, volume, dynamometry, and thermography) and questionnaires application to assess patient's quality of life pertaining to the health, functionality, and symptoms of the affected upper limb, as well adverse effects and adherence to treatment. Data will be analyzed descriptively and analytically through univariate and multiple linear regressions. P values < 0.05 will be considered statistically significant.

DISCUSSION

This study will evaluate the effectiveness of a self-adjustable garment (ReadyWrap®) in the treatment of lymphedema secondary to breast cancer in Brazilian women compared to the gold standard treatment for limb volume reduction (phase 1) and maintenance (phase 2) phases comprising, respectively, a compressive bandaging and a compressive mesh. The outcome results will provide data based on both quantitative responses and self-reported participant outcomes. The study will also assess the cost-effectiveness of the ReadyWrap® treatment versus standard care. Finally, we expect to reaffirm one more product/therapy as a treatment for this extremely complex and impactful condition following the data analysis.

Prevention of lymphoedema after axillary clearance by external compression sleeves PLACE randomised trial results. Effects of high BMI

Around 25% of women undergoing Axillary Clearance (ANC) develop lymphedema (LE). Intervention with a compression garment is recommended to prevent LE but no randomised evidence exists to support this strategy.

METHODS

A randomised trial tested standard management versus application of graduated compression garments (20-24 mmHg) to affected arm, for 1 year. Women with node positive breast cancer (n = 1300) undergoing ANC consented to arm volume measurements and those developing a 4-9% relative arm volume increase (RAVI) (subclinical LE) within 9 months post-surgery were randomised. Primary outcome was proportion of patients developing LE (RAVI > 10%) by 24-months in each group. Secondary endpoints included Quality of life in each group.

RESULTS

In total 143 patients were randomised (74 no sleeve: 69 compression sleeve) between October 2010 and November 2015. The lymphoedema rate at 24 months in the 'no sleeve' group was at 41%, similar to the 'sleeve' group (30%: p = 0.32). Thirtytwo patients randomised to the 'no sleeve' group had a sleeve applied within 24 months. Body Mass Index (BMI) at randomisation predicted LE at any time point HR 1.04 (CI 1.01-1.08; p = 0.01). Patients with obesity (BMI > 30) had higher rates of LE in both groups (46%) compared to those with BMI < 30 (24%). No difference between patients was found in either group in changes in QoL. Compression sleeves applied after development of LE improved QoL scores (FACT-B p = 0.007:TOI p = 0.042).

CONCLUSION

Early intervention with External Compression garments does not prevent clinical LE, particularly in women with a high BMI > 30. The use of prophylactic garments in subclinical LE (RAVI < 9%) is unwarranted.

Early Detection of Breast Cancer-Related Lymphedema in COVID-19 Pandemic

Background: This study aimed at presenting a prospective surveillance model of care delivered at home for women qualified for surgery due to breast cancer under the epidemic-related restrictions. Methods and Results: Women (age ≥18 years, diagnosed with breast cancer, no clinical features of upper limbs lymphedema, and a volume difference between the limbs <5%, not using any prophylactic compression products) will be provided with comprehensive education in the field of self-measurements and lymphedema prevention. The outcome measures include limb volume (circumferential measurements with a tape at 4 cm intervals), simplified protocol of three measurement points combined with the symptoms monitoring (according to the physical section of Lymphedema Quality of Life Inventory [LyQLI]). We propose a new calculation method as the RACI (relative arm circumference increase) in accordance with previous research-RAVI (relative arm volume increase) and the new proposal-the RACD (relative arm circumference difference). According to cylinder formula it can be calculated that 5% increase in limb volume results in ∼2% change in RACI. Regular appointments will be planned at 3, 6, 9, and 12 months after the enrollment. Additional urgent appointments will be arranged after the home or phone "red flags" (an increase circumference by ≥2%, positive pitting test, and any new symptoms) detection. We hypothesize that performing only three measurements combined with the typical symptoms monitoring would be accurate for lymphedema diagnosis based on the RAVI of ≥5%. Moreover, RACI/RACD increments combined with positive symptoms would correlate with RAVI. Conclusions: The new proposal of protocol can be the optimal solution in COVID-19 pandemic.

Systematic Review of Functional Outcomes in Cancer Rehabilitation

OBJECTIVE

To systematically review the evidence regarding rehabilitation interventions targeting optimal physical or cognitive function in adults with a history of cancer and describe the breadth of evidence as well as strengths and limitations across a range of functional domains.

DATA SOURCES

PubMed, Cumulative Index to Nursing and Allied Health Plus, Scopus, Web of Science, and Embase. The time scope was January 2008 to April 2019.

STUDY SELECTION

Prospective, controlled trials including single- and multiarm cohorts investigating rehabilitative interventions for cancer survivors at any point in the continuum of care were included, if studies included a primary functional outcome measure. Secondary data analyses and pilot/feasibility studies were excluded. Full-text review identified 362 studies for inclusion.

DATA EXTRACTION

Extraction was performed by coauthor teams and quality and bias assessed using the American Academy of Neurology (AAN) Classification of Evidence Scheme (class I-IV).

DATA SYNTHESIS

Studies for which the functional primary endpoint achieved significance were categorized into 9 functional areas foundational to cancer rehabilitation: (1) quality of life (109 studies), (2) activities of daily living (61 studies), (3) fatigue (59 studies), (4) functional mobility (55 studies), (5) exercise behavior (37 studies), (6) cognition (20 studies), (7) communication (10 studies), (8) sexual function (6 studies), and (9) return to work (5 studies). Most studies were categorized as class III in quality/bias. Averaging results found within each of the functional domains, 71% of studies reported statistically significant results after cancer rehabilitation intervention(s) for at least 1 functional outcome.

CONCLUSIONS

These findings provide evidence supporting the efficacy of rehabilitative interventions for individuals with a cancer history. The findings should be balanced with the understanding that many studies had moderate risk of bias and/or limitations in study quality by AAN criteria. These results may provide a foundation for future work to establish clinical practice guidelines for rehabilitative interventions across cancer disease types.

Prophylactic Use of Compression Sleeves Reduces the Incidence of Arm Swelling in Women at High Risk of Breast Cancer-Related Lymphedema: A Randomized Controlled Trial

PURPOSE

To determine whether prophylactic use of compression sleeves prevents arm swelling in women who had undergone axillary lymph node dissection for breast cancer surgery.

METHODS

Women (n = 307) were randomly assigned to either a compression or control group. In addition to usual postoperative care, the compression group received two compression sleeves to wear postoperatively until 3 months after completing adjuvant treatments. Arm swelling was determined using bioimpedance spectroscopy (BIS) thresholds and relative arm volume increase (RAVI). Incidence and time free from arm swelling were compared using Kaplan-Meier analyses. Hazard ratios (HRs) were estimated from Cox regression models for BIS and RAVI thresholds independently. In addition, time to documentation of the first minimally important difference (MID) in four scales of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and the breast cancer-specific (BR23) questionnaire was analyzed.

RESULTS

The HR for developing arm swelling in the compression group relative to the control group was 0.61 (95% CI, 0.43 to 0.85; P = .004) on the basis of BIS and 0.56 (95% CI, 0.33 to 0.96; P = .034) on the basis of RAVI. The estimated cumulative incidence of arm swelling at 1 year was lower in the compression group than the control group on the basis of BIS (42% v 52%) and RAVI (14% v 25%). HRs for time from baseline to the first change of the minimally important difference were not statistically significant for any of the four scales of EORTC QLQ-30 and BR23 questionnaires.

CONCLUSION

Prophylactic use of compression sleeves compared with the control group reduced and delayed the occurrence of arm swelling in women at high risk for lymphedema in the first year after surgery for breast cancer.

A 24-hour interval compression plan for managing chronic oedema: part 1-the science and theory behind the concept

Compression, skin care, manual lymph drainage and exercise form the mainstays of treatment of chronic limb oedema. The compression aspect of the regimen is often prescribed and used without conscious concern for the patient's ability for self-adjustment and skin hygiene. This article will focus on the action of compression therapy using a new concept of encouraging patients to apply and reapply an adjustable compression garment or multiple garment types during a 24-hour interval. The benefits of this focus on interval compression therapy on all aspects of care will be explained and case studies presented.

Design of an Auxiliary Artificial Lymphatic Vessel in Treatment of Secondary Lymphedema Due to Breast Cancer

Breast cancer is the most common malignant tumor that affects women in the United States, Europe, and Mexico. As an adverse effect when performing treatments for this condition, secondary lymphedema associated with breast cancer occurs in some cases. This complication occurs due to the interruption of lymphatic flow in the upper extremities in conjunction with other factors such as radiation, sedentary lifestyle, removal of lymph nodes, damage to lymphatic vessels, and others. This article reviews breast cancer incidence, mortality, and survival patterns, confirming that, specifically, lymphedema has high health, social, and economic impacts. Research demonstrates that it fundamentally affects women at an early age. In approximately a third of the cases, it becomes a chronic disease. Therefore, physical therapy is essential for a better quality of life in patients who survive this disease. Surgeries and manual and pharmacological treatments are the current procedures done to reduce to reduce the alterations suffered by patients with lymphedema; however, the success of the treatments depends on each patient’s characteristics. To face this problem, the design of a lymphatic vessel has been proposed to assist the mechanical failure of the damaged lymphatic system. In this work, the design methodology used for the blueprint of the lymphatic vessel is presented, as well as the computer analysis of fluid simulation and the selection of the proposed material, resulting in the production of a micrometric design. In the future, it is expected that a surgeon will be able to implant the design of the vessel to restore lymph flow through the lymphatic system, thus helping to combat lymphedema.

Compression Therapy for the Patients With Breast Cancer: A Meta-analysis of Randomized Controlled Trials

BACKGROUND

Compression therapy is a common method for treating breast cancer-related lymphedema. However, no specific evidence exists to guide practitioners on the morbidity of lymphedema, limb volume, and range of motion.

OBJECTIVE

The aims of this study were to compare the effects of compression therapy and routine nursing during the treatment of breast cancer-related lymphedema and to provide a basis for better clinical decision-making.

METHODS

The PubMed, Cochrane Library, EMBASE, Web of Science, CBM, CNKI, Wanfang, and VIP databases were searched through January 21, 2021. Meta-analysis and description of the outcomes were performed by using the RevMan 5.3 software.

RESULTS

A total of 17 studies were included. A meta-analysis of 13 studies was conducted. The experimental group had a lower morbidity of lymphedema, the difference was significant, and there was no heterogeneity (P < .05; odds ratio, 0.35, I2 = 31%). There was no significant difference between the experimental group and control group in limb volume, and there was significant heterogeneity (P = .44, mean difference = 4.51, I2 = 85%). Regarding range of motion, the standardized mean difference of shoulder adduction, shoulder lift, shoulder abduction, and shoulder extension were 1.37, 0.69, 0.56, and 0.87, respectively, and the differences were significant; there was heterogeneity (P < .05, I2 = 92%).

CONCLUSIONS

Compression therapy can reduce the morbidity of lymphedema and improve limb movement, but the effect on limb volume needs to be further explored.

IMPLICATION FOR PRACTICE

In terms of therapeutic effectiveness and limb function, the results provide evidence that physicians can reduce the morbidity of lymphedema, reduce the degree of limb, and increase limb mobility by applying compression therapy.

The impact of lymphedema on health-related quality of life up to 10 years after breast cancer treatment

The impact of breast cancer-related lymphedema (BCRL) on long-term quality of life is unknown. The aim of this study was to investigate the impact of BCRL on health-related quality of life (HRQoL) up to 10 years after breast cancer treatment. This regional population-based study enrolled patients treated for breast cancer with axillary lymph node dissection between January 1st 2007 and December 31th 2017. Follow up and assessments of the included patients were conducted between January 2019 and May 2020. The study outcome was HRQoL, evaluated with the Lymphedema Functioning, Disability and Health Questionnaire, the Disabilities of the Arm, Shoulder and Hand Questionnaire and the Short Form (36) Health Survey Questionnaire. Multivariate linear logistic regression models adjusted for confounders provided mean score differences (MDs) with 95% confidence intervals in each HRQoL scale and item. This study enrolled 244 patients with BCRL and 823 patients without BCRL. Patients with BCRL had significantly poorer HRQoL than patients without BCRL in 16 out of 18 HRQoL subscales, for example, in physical function (MDs 27, 95%CI: 24; 30), mental health (MDs 24, 95%CI: 21; 27) and social role functioning (MDs 20, 95%CI: 17; 23). Age, BMI, BCRL severity, hand and dominant arm affection had only minor impact on HRQoL (MDs < 5), suggesting a high degree of inter-individual variation in coping with lymphedema. This study showed that BCRL is associated with long-term impairments in HRQoL, especially affecting the physical and psychosocial domains. Surprisingly, BCRL diagnosis rather than clinical severity drove the largest impairments in HRQoL.

Breast Cancer-Related Lymphedema: Recent Updates on Diagnosis, Severity and Available Treatments

Breast cancer-related lymphedema (BCRL) represents a global healthcare issue affecting the emotional and life quality of breast cancer survivors significantly. The clinical presentation is characterized by swelling of the affected upper limb, that may be accompanied by atrophic skin findings, pain and recurrent cellulitis. Cardinal principles of lymphedema management are the use of complex decongestive therapy and patient education. Recently, new microsurgery procedures have been reported with interesting results, bringing in a new opportunity to care postmastectomy lymphedema. However, many aspects of the disease are still debated in the medical community, including clinical examination, imaging techniques, patient selection and proper treatment. Here we will review these aspects and the current literature.

Managing Lymphedema, Increasing Range of Motion, and Quality of Life through Yoga Therapy among Breast Cancer Survivors: A Systematic Review

Lymphedema is a common complication of breast cancer treatment. Yoga is a nonconventional and noninvasive intervention that is reported to show beneficial effects in patients with breast cancer-related lymphedema (BCRL). This study attempted to systematically review the effect of yoga therapy on managing lymphedema, increasing the range of motion (ROM), and quality of life (QOL) among breast cancer survivors. The review search included studies from electronic bibliographic databases, namely Medline (PubMed), Embase, and Google Scholar till June 2019. Studies which assessed the outcome variables such as QOL and management of lymphedema or related physical symptoms as effect of yoga intervention were considered for review. Two authors individually reviewed, selected according to Cochrane guidelines, and extracted the articles using Covidence software. Screening process of this review resulted in a total of seven studies. The different styles of yoga employed in the studies were Iyengar yoga (n = 2), Satyananda yoga (n = 2), Hatha yoga (n = 2), and Ashtanga yoga (n = 1). The length of intervention and post intervention analysis ranged from 8 weeks to 12 months. Four studies included home practice sessions. QOL, ROM, and musculoskeletal symptoms showed improvement in all the studies. Yoga could be a safe and feasible exercise intervention for BCRL patients. Evidence generated from these studies was of moderate strength. Further long-term clinical trials with large sample size are essential for the development and standardization of yoga intervention guidelines for BCRL patients.

A randomized study to prevent lymphedema in women treated for breast cancer: CALGB 70305 (Alliance)

BACKGROUND

Lymphedema affects many women who are treated for breast cancer. We examined the effectiveness of an education-only (EO) versus education plus sleeve compression/exercise intervention (lymphedema education and prevention [LEAP]) on lymphedema incidence and range of motion (ROM) in a group-randomized trial across 38 cooperative group sites.

METHODS

The treating institution was randomly assigned to either EO or LEAP by a study statistician. All patients at a treating institution participated in the same intervention (EO or LEAP) to minimize contamination bias. Participants completed surveys, arm volume measurements, and self-reported ROM assessments before surgery and at 12 and 18 months after surgery. Lymphedema was defined as a ≥10% difference in limb volume at any time post-surgery up to 18 months after surgery or diagnosis by a health provider. Cochran-Mantel-Haenszel tests were used to compare lymphedema-free rates between groups, stratified by lymph node surgery type. Self-reported ROM differences were compared between groups.

RESULTS

A total of 554 participants (56% LEAP) were included in the analyses. At 18 months, lymphedema-free rates were 58% (EO) versus 55% (LEAP) (P = .37). ROM for both arms was greater in LEAP versus EO at 12 months; by 18 months, most women reported full ROM, regardless of group. In LEAP, only one-third wore a sleeve ≥75% of the time; 50% performed lymphedema exercises at least weekly.

CONCLUSION

Lymphedema incidence did not differ by intervention group at 18 months. Poor adherence in the LEAP group may have contributed. However, physical therapy may speed recovery of ROM. Further research is needed to effectively reduce the incidence and severity of lymphedema in patients who have breast cancer.

Psychosocial Issues Associated with Breast Cancer-Related Lymphedema: a Literature Review

PURPOSE OF REVIEW

Breast cancer-related lymphedema (BCRL) is a chronic disease affecting breast cancer survivors. The purpose of this article is to update the scientific literature regarding psychosocial issues associated with BCRL.

RECENT FINDINGS

Reports describe economic burdens, social support, sexuality, BCRL patient-education needs, and interventions to reduce BCRL symptoms and improve QOL among women with breast cancer. The psychosocial impact of BCRL may differ between younger and older women which has implications for age-related interventions to reduce the adverse psychosocial experiences of women with BCRL. We did not locate studies reporting the psychosocial impact of BCRL on male breast cancer survivors.

SUMMARY

More psychosocial-based interventions are needed that target the concerns of those with BCRL, including age-related needs, sexual concerns, body image, and social support. Future research is indicated to study the psychosocial impact of BCRL among men. Researchers may consider how pandemic-driven health care policies affect the psychosocial needs of those with BCRL.

Lymphedema in survivors of breast cancer

The tremendous improvement of survival in patients with breast cancer can be attributed to several treatment strategies, but these strategies also lead to the occurrence of breast cancer-related lymphedema (BCRL). BRCL is regularly associated with factors such as axillary lymph node dissection and local lymph node radiotherapy and manifests as an increase of >10% in the volume of affected limbs. Being overweight or having obesity (body mass index ≥25 kg/m2), an excessive number of positive lymph nodes (>8) and capsular invasion by a tumor are additional risk factors for lymphedema. It is worth assessing the risk before surgery as this can prevent the occurrence of BCRL at the initial stage of breast cancer management. The clinical utility of many diagnostic tools and lymphedema surveillance allows early stage and even subclinical BCRL to be diagnosed, and allows real-time monitoring of the disease. The early diagnosis of BRCL allows treatment at an early stage, which is beneficial to the reduction of excess limb volume and the improvement of quality of life. At present, the major therapeutic methods of BCRL include complex decongestive therapy, pneumatic compression devices, participating in exercise, microsurgery and liposuction, each of which alleviates lymphedema effectively. No medications for treatment of BRCL have yet been developed. However, the recent findings on the success of molecular therapy in animal models may remedy this deficiency. Furthermore, the volume reduction of swollen limbs without swelling rebound by transplanting autologous stem cells has been successfully reported in some pilot studies, which may provide a new technique for treating BCRL. This review aimed to discuss the pathogenesis, clinical manifestation, risk factors, advantages and disadvantages of diagnostic tools, lymphedema surveillance and the characteristics of traditional and newly emerging BCRL treatments.
