Use of a prospective surveillance model to prevent breast cancer treatment-related lymphedema: a single-center experience

Association Between Symptom Burden and Early Lymphatic Abnormalities After Regional Nodal Irradiation for Breast Cancer

PURPOSE

Dermal backflow visualized on near-infrared fluorescence lymphatic imaging (NIRF-LI) signals preclinical lymphedema that precedes the development of volumetrically defined lymphedema. We sought to evaluate whether dermal backflow correlates with patient-reported lymphedema outcomes (PRLO) surveys in breast cancer patients treated with regional nodal irradiation (RNI).

METHODS AND MATERIALS

Patients with breast cancer planned for axillary dissection and RNI prospectively underwent perometry, NIRF-LI, and PRLOs (the Lymphedema Symptom Intensity and Distress Survey [LSIDS] and QuickDASH) at baseline, after surgery, and at 6, 12, and 18 months after radiation. Clinical lymphedema was defined as an arm volume increase ≥5% over baseline. Trends over time were assessed using analysis of variance testing. The association between survey responses and both dermal backflow and lymphedema was assessed using a linear mixed-effects model.

RESULTS

Sixty participants completed at least 2 sets of measurements and surveys and were eligible for analysis. Fifty-four percent of patients had cT3-T4 disease, 53% cN3 disease, and 75% had a body mass index >25. Dermal backflow and clinical lymphedema increased from 10% to 85% and from 0% to 40%, respectively, from baseline to 18 months. In the adjusted model, soft tissue sensation, neurologic sensation, and functional LSIDS subscale scores were associated with presence of dermal backflow (all P < .05). Both dermal backflow and lymphedema were associated with QuickDASH score (P < .05).

CONCLUSIONS

In this high-risk cohort, we found highly prevalent early signs of lymphedema, with increased symptom burden from baseline. Presence of dermal backflow correlated with PRLO measures, highlighting a potential NIRF-LI use to identify patients for early intervention trials after RNI.

Reducing rates of chronic breast cancer-related lymphedema with screening and early intervention: an update of recent data

PURPOSE

Breast cancer-related lymphedema (BCRL) represents a dreaded complication of breast cancer treatment that can lead to morbidity, diminished quality of life, and psychosocial harm and is associated with increased costs of care. Increasingly, data has supported the concept of prospective BCRL surveillance coupled with early intervention to mitigate these effects.

METHODS

We performed a systematic review of the literature searching for published randomized and prospective data evaluating prospective BCRL surveillance with early intervention.

RESULTS

We identified 12 studies (2907 patients) including 4 randomized trials (1203 patients) and 8 prospective studies (1704 patients). Randomized data consistently demonstrate that early intervention reduces rates of progression to chronic BCRL with multiple paradigms and diagnostic modalities utilized; the strongest data comes from the randomized PREVENT trial, which demonstrated early detection with bioimpedance spectroscopy (BIS), coupled with early intervention with a compression garment applied for 12 h a day over 4 weeks, significantly reduced the rate of chronic BCRL compared to tape measurement coupled with early intervention.

CONCLUSIONS

Current data support the role of prospective BCRL surveillance with early detection and intervention to reduce rates of chronic BCRL. Breast cancer patients at risk for BCRL should undergo prospective surveillance as part of survivorship. Because level 1 data demonstrate that BIS is superior to conventional tape measure, it should be included as the standard BCRL diagnostic modality unless an equally effective modality is employed.

IMPLICATIONS FOR CANCER SURVIVORS

Breast cancer survivor should undergo prospective BCRL screening with BIS.

Bibliometric analysis of breast cancer-related lymphedema research trends over the last 2 decades

Objective

This study aims to conduct a comprehensive bibliometric analysis of Breast Cancer-Related Lymphedema (BCRL) research from 2003 to 2022, identifying trends and providing global research insights for future studies.

Method

The literature for this analysis was extracted from the Web of Science (WoS) Core Collection, encompassing 1199 publications, including 702 articles and 101 reviews, totaling 803. Using advanced bibliometric tools such as VOSviewer and CiteSpace, quantitative and visual analyses were performed to map collaboration networks, research clusters, and emerging trends. The search strategy included specific terms related to lymphedema, breast cancer, and BCRL, ensuring a comprehensive representation of the research landscape.

Results

The bibliometric analysis revealed a steady increase in BCRL publications over the studied period, reaching a peak in 2018. The United States emerged as the leading contributor to BCRL literature, with China also demonstrating a significant presence. Collaboration networks were visualized, showcasing the interconnectedness of institutions and researchers globally. Key research hotspots identified include preventive strategies, complex decongestive therapy, and reconstructive interventions.

Conclusion

In conclusion, this pioneering bibliometric analysis provides a comprehensive overview of BCRL research trends and collaborations globally. The findings contribute valuable insights into the evolution of the field, highlighting areas of focus and emerging research themes. This study serves as a foundational resource for researchers, clinicians, and policymakers, fostering evidence-based practices and interventions for BCRL in the future.

Breast Cancer-Related Lymphedema (BCRL) and Bioimpedance Spectroscopy: Long-Term Follow-Up, Surveillance Recommendations, and Multidisciplinary Risk Factors

BACKGROUND

Early detection and intervention for breast cancer-related lymphedema (BCRL) significantly decreases progression to persistent BCRL (pBCRL). We aimed to provide long-term follow-up on our early detection with bioimpedance spectroscopy (BIS) and early home intervention demonstrating reduced pBCRL to guide surveillance recommendations.

PATIENTS AND METHODS

In total, 148 female patients with breast cancer who had axillary lymph node dissection (ALND) from November 2014 to December 2017 were analyzed. Baseline BIS measurements and postoperative follow-up occurred every 3 months for 1 year, biannual for 1 year, and then annually. An elevated BIS triggered evaluation and initiation of at-home interventions with reassessment for resolution versus persistent BCRL (pBCRL). High-risk factors and timing were analyzed.

RESULTS

Mean follow-up was 55 months, and 65 (44%) patients had an abnormal BIS. Of these, 54 (82%) resolved with home intervention. The overall pBCRL rate was 8%. Average time to first abnormal BIS was 11.7 months. None of the stage 0 patients (0/34) and only 5/25 (20%) of stage 1 patients had pBCRL. All of stage 2 and stage 3 patients (7/7) had pBCRL. pBCRL correlated with number of positive nodes, percentage of positive nodes, stage of lymphedema at diagnosis, and recurring abnormal BIS measurements (p < 0.05).

CONCLUSIONS

We have shown that patients undergoing ALND with early BCRL identified by BIS who performed home interventions had an 8% pBCRL rate. Patients at high risk for pBCRL should have routine surveillance starting at 9 months postoperatively to identify an opportunity for early intervention.

Implementing and sustaining a breast cancer prospective surveillance rehabilitation program: an institutional perspective

BACKGROUND

The prospective surveillance model (PSM) is an evidence-based rehabilitation care delivery model that facilitates functional screening and intervention for individuals undergoing cancer treatment. While PSM is empirically validated and feasible in practice, implementation into cancer care delivery has languished. The purpose of this manuscript is to characterize the barriers and facilitators to implementing PSM in a breast cancer center and to share policy and process outcomes that have sustained the model in practice.

METHODS

The PSM implementation was undertaken as a quality improvement initiative of our cancer center. We retrospectively assessed barriers to implementation and define those according to the Consolidated Framework for Implementation Research (CFIR). Implementation strategies are defined based on the Expert Recommendations for Implementation Change (ERIC) taxonomy. Breast center policy changes and stakeholder-reported process improvement outcomes at the clinic and system level are described.

RESULTS

PSM implementation facilitation was driven primarily by adapting the model to align with the cancer center workflow, engaging interdisciplinary stakeholders as program champions, enhancing knowledge and awareness among cancer care providers, and changing infrastructure to support the model. System and clinic-level policy and process changes included the development of clinical pathways, EHR order sets and automated referrals, new staffing models, and adapted clinical workflows.

CONCLUSION

Our report provides insight on implementing the PSM at a single institution in a cancer care delivery setting. Successful implementation strategies addressed individual, clinic, and system-level barriers and facilitated process and policy changes that have enabled PSM sustainment. Improving integration of rehabilitation services into oncology care has significant implications for survivorship care by enhancing proactive management of functional morbidity.

IMPLICATIONS FOR CANCER SURVIVORS

Improving integration of rehabilitation services into oncology care has significant implications for survivorship care by enhancing proactive management of functional morbidity.

Current Diagnostic Tools for Breast Cancer-Related Lymphedema

PURPOSE OF REVIEW

Breast cancer-related lymphedema (BCRL) can have a significant impact on breast cancer survivors quality of life. The purpose of this review is to evaluate diagnostic tools for the assessment of BCRL.

RECENT FINDINGS

Multiple BCRL diagnostic tools are available, though older diagnostic tools have low sensitivity, limiting the ability for sub-clinical BCRL diagnosis while BIS and perometry have increased sensitivity and the ability to diagnose BCRL sub-clinically. Prospective studies have demonstrated such an approach coupled to early intervention is associated with low rates of chronic BCRL while a recently published randomized trial demonstrated that prospective surveillance with BIS coupled with early intervention reduced rates of chronic BCRL as compared to circumference measurements with compression garments. Prospective and randomized data support the use of prospective surveillance for BCRL. The strongest data available comes from the PREVENT trial and supports prospective BCRL surveillance with bioimpedance spectroscopy coupled to early intervention with a compression sleeve.

Validation of a Lymphedema Index Score Based on Noncontrast Magnetic Resonance Lymphangiography: Correlation with Clinical Staging and Indocyanine Green Lymphangiography

Background: A standardized lymphedema grading system is a prerequisite for accurately and objectively evaluating its severity, both preoperatively and postoperatively. The purpose of this study was to establish a clinically feasible noncontrast magnetic resonance lymphangiography (NMRL) protocol and a standardized scoring system for the evaluation of lymphedema. Methods and Results: From January 2020 to February 2021, 39 patients who had been clinically diagnosed with lymphedema and had undergone NMRL were included. The severity and circumferential extent of lymphedema were assessed using magnetic resonance imaging, and a combined index was devised as the sum of the product of the severity and extent scores determined at four different levels. A magnetic resonance imaging (MRI) stage was allocated based on the combined index score, its correlation with clinical indices was analyzed. The MR and clinical staging showed a percentage agreement of 85.9% and a kappa coefficient of 0.641, indicating moderate agreement (p < 0.001). Both the interlimb volume and interlimb impedance ratios differed significantly between groups (p < 0.001 for both). The correlation analysis revealed a significant correlation between the combined index score and the inter-limb volume ratio (r = 0.70, p < 0.001) and inter-limb impedance ratio at both 1 kHz (r = 0.71, p < 0.001) and 5 kHz (r = 0.71, p < 0.001). The interobserver agreement was moderate for the severity score, extent score, and combined score. Conclusion: The proposed standardized scoring system for evaluating lymphedema based on NMRL can reproducibly determine the severity and extent of lymphedema in both the upper and lower extremities, and correlates strongly with established clinical measures.

Rehabilitation interventions for the management of breast cancer-related lymphedema: developing a patient-centered, evidence-based plan of care throughout survivorship

PURPOSE

A work group from the American Physical Therapy Association Academy of Oncologic Physical Therapy developed and published a clinical practice guideline (CPG) to aid clinicians in identifying interventions for individuals with breast cancer-related lymphedema (BCRL). This guideline reviewed the evidence for risk mitigation and volume reduction beginning at cancer diagnosis and continuing through survivorship. Application of CPGs can be challenging due to the variability of clinical settings, heterogeneous patient populations, and range of rehabilitation clinician expertise. The purpose of this paper is to assist these clinicians in implementing the recommendations from the CPG to develop a patient-centered, evidence-based plan of care.

METHODS/RESULTS

This publication presents important considerations for the implementation of recommended rehabilitation interventions across the trajectory of BCRL.

CONCLUSION

Current evidence supports specific interventions to treat or mitigate the risk for the various stages of BCRL. As clinicians implement these recommendations into practice, they also need to address other impairments that may exist in every individual. Continued collaboration between clinicians and researchers is necessary to further develop optimal treatment modalities and parameters.

IMPLICATIONS FOR CANCER SURVIVORS

By implementing evidence-based interventions as outlined in the CPG, clinicians can improve the quality of care for survivors of breast cancer.

Cancer Rehabilitation Fact Sheet in Korea

Cancer rehabilitation aims to enable patients to maximize their physical, social, psychological, and vocational functions within the limits that arise during the course of the disease and its treatment. According to recent domestic studies, most patients report one or more physical problems during or after cancer treatment. This review presents the latest updates on cancer-related rehabilitation issues. Cancer rehabilitation in Korea still faces various barriers, including a lack of awareness, problems with the healthcare delivery system, and high costs, and recognizing the need for rehabilitation during cancer treatment varies among patients and even physicians. Hence, an appropriate cooperative referral system for cancer rehabilitation requires improvement. We herein review the current status of and barriers to cancer rehabilitation in South Korea to resolve the issues of domestic cancer rehabilitation.

Early intervention with compression garments prevents progression in mild breast cancer-related arm lymphedema: a randomized controlled trial

BACKGROUND

Early diagnosis and compression treatment are important to prevent progression in breast cancer-related arm lymphedema (BCRAL). However, some mild BCRAL can be reversible, and therefore, compression treatment may not be needed. The aim of this study was to investigate the proportion of women with mild BCRAL showing progression/no progression of lymphedema after treatment with or without compression garments, differences in changes of lymphedema relative volume (LRV), local tissue water and subjective symptoms during 6 months. Also, adherence to self-care was examined.

MATERIAL AND METHODS

Seventy-five women diagnosed with mild BCRAL were randomized to a compression group (CG) or noncompression group (NCG). Both groups received self-care instructions, and the CG were treated with a standard compression garment (ccl 1). Women in the NCG who progressed in LRV ≥2%, or exceeded 10% dropped out, and received appropriate treatment. The proportion showing progression/no progression of LRV, and changes in LRV was measured by Water Displacement Method. Changes in local tissue water were measured by Tissue Dielectric Constant (TDC), subjective symptoms by Visual Analogue Scale, and self-care by a questionnaire.

RESULTS

A smaller proportion of LRV progression was found in the CG compared to the NCG at 1, 2 and 6 months follow-up (p ≤ 0.013). At 6 months, 16% had progression of LRV in the CG, compared to 57% in the NCG, (p = 0.001). Thus, 43% in the NCG showed no progression and could manage without compression. Also, CG had a larger reduction in LRV, at all time-points (p ≤ 0.005), and in the highest TDC ratio, when same site followed, at 6 months (p = 0.025). Subjective symptoms did not differ between the groups, except at 1 month, where the CG experienced more reduced tension (p = 0.008). There were no differences in adherence to self-care.

CONCLUSION

Early treatment with compression garment can prevent progression in mild BCRAL. Trial registration: ISRCT nr ISRCTN51918431.

Prospective Surveillance for Breast Cancer-Related Arm Lymphedema: A Systematic Review and Meta-Analysis

PURPOSE

The call to integrate prospective surveillance for lymphedema into cancer care pathways is building momentum to enable early intervention and prevent the progression of the condition. We offer a critical evaluation of the literature on prospective surveillance and early management for cancer-related lymphedema and evaluate the effect of such programs in preventing chronic lymphedema (CRD42019137965).

METHODS

Five databases and two registries were searched for randomized controlled trials or observational studies that assessed the incidence or prevalence of lymphedema associated with participation in a prospective surveillance program, published until February 26, 2021. Numbers triggered for early lymphedema management, resolved, and chronic lymphedema were extracted. Pooled relative risk (trials) and pooled rate (cumulative incidence; observational studies) of chronic lymphedema was calculated. Subgroup analyses assessed the effect of study design, length of follow-up, and extent of axillary surgery.

RESULTS

Twenty-three studies were included, of which 21 studies evaluated breast cancer-related arm lymphedema (BCRaL). Participation in prospective surveillance with early management reduced the risk of chronic BCRaL versus usual care (relative risk 0.31; 95% CI, 0.10 to 0.95; two randomized controlled trials; N = 106). The pooled rate of chronic BCRaL was 4% (95% CI, 3 to 6; 15 observational studies; N = 3,545), and 6% (95% CI, 4 to 9) when restricted to participants with axillary lymph node dissection (12 studies; N = 1,527).

CONCLUSION

The findings suggest that participation in prospective surveillance with early management reduces the risk of chronic BCRaL. Only a minority of patients at high risk of lymphedema because of axillary surgery developed chronic lymphedema. More robust research is needed to determine whether prospective surveillance with early management can reduce the risk of chronic lymphedema, particularly among cancer survivors other than breast cancer.

Study protocol for a 10-year prospective observational study, examining lymphoedema and patient-reported outcome after breast reconstruction

INTRODUCTION

Over the last decades, treatment of breast cancer has become increasingly more effective. Consequently, an increasing number of women are living with late effects of breast cancer treatment, including disfiguring scars, deformity or asymmetry of the breast, secondary lymphoedema and other physical and psychosocial late effects. Data from this study will provide knowledge on how to guide breast reconstruction in the future towards outcomes with fewer complications, higher long-term quality of life (QoL) and satisfaction with the aesthetic outcome. The development of secondary lymphoedema, for which the effect of breast reconstruction has yet to be established, will be thoroughly examined.

METHODS AND ANALYSIS

Women receiving breast reconstruction (autologous and implant based) at the Department of Plastic Surgery and Burns Treatment, Rigshospitalet, will be invited to participate. The patients will be followed for 10 years postoperatively. Demographic, health-related, oncological characteristics and treatment data will be registered. Validated assessment tools, such as the BREAST-Q and Beck Depression Inventory, will be used to measure an extensive range of clinical outcomes, including QoL, life and aesthetic satisfaction and depression. Arm range of motion will be measured with a goniometer and lymphoedema by bioimpedance spectroscopy, compared with circular arm measurements.

ETHICS AND DISSEMINATION

This study will be conducted according to the 5th version of the Helsinki Declaration. The regional ethical committee for Capital Region Denmark did not find the study notifiable, according to the law of the committee § 1, part 4. All data will be anonymised before its publication. This study will be conducted according to the Danish data protection regulation and is catalogued and approved by the Capital Region Head of Knowledge Centre. According to the Danish health law § 46, part 2, this study does not need the Danish Patient Safety Authority's approval. The findings of this study will be submitted to international peer-reviewed journals.

ONS Guidelines™ for Cancer Treatment-Related Lymphedema

PURPOSE

Lymphedema is a chronic condition that may result from cancer-related surgery. The incidence of lymphedema varies greatly; however, patients remain at risk for life and may experience decreased quality of life and functional capacity. Providing recommendations for an evidence-based guideline for care of cancer treatment-related lymphedema will help to improve outcomes for patients with this chronic condition.

METHODOLOGIC APPROACH

A panel of healthcare professionals with patient representation convened to develop a national clinical practice guideline on prospective surveillance, risk reduction, and conservative treatment of lymphedema. Systematic reviews of the literature were conducted and the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) methodology approach was used to assess the evidence.

FINDINGS

The panel made multiple recommendations for patients who are at risk for or experiencing lymphedema.

IMPLICATIONS FOR NURSING

Early diagnosis and treatment of lymphedema may mitigate symptoms. This evidence-based guideline supports patients, clinicians, and other healthcare professionals in clinical decision making.

Limitations of Current Rehabilitation Practices in Pediatric Oncology: Implications for Improving Comprehensive Clinical Care

OBJECTIVE

To identify the proportion of hospitals/clinics in the United States (US) that have a comprehensive pediatric oncology rehabilitation program and characterize current practices.

DESIGN

Cross-sectional survey of rehabilitation providers in the US and internationally.

SETTING

Electronic or telephone survey.

PARTICIPANTS

Rehabilitation or supportive care practitioners employed at a hospital, outpatient clinic, or medical university.

INTERVENTIONS

Electronic and telephone survey. The full electronic survey contained 39 questions, provided opportunities for open-ended responses, and covered 3 main categories specific to pediatric cancer rehabilitation: service delivery, rehabilitation program practices, and education/training. The short telephone survey included 4 questions from the full survey and was designed to answer the primary study objective.

MAIN OUTCOME MEASURES

Proportion of hospitals/clinics with a comprehensive pediatric oncology rehabilitation program.

RESULTS

This cohort (N=241) includes rehabilitation providers from 191 hospitals/clinics, 49 states within the US, and 5 countries outside of the US. Of hospitals/clinics represented from the full and short survey, 145 (76%) do not have an established pediatric oncology rehabilitation program. Nearly half of full survey respondents reported no knowledge of the prospective surveillance model (PSM) and 65% reported no education was provided to them regarding pediatric cancer rehabilitation. Qualitative survey responses fell into three major themes: variability in approach to rehabilitation service delivery, program gaps, and the need for additional educational opportunities.

CONCLUSIONS

There is evidence of limited comprehensive rehabilitation programming for children with cancer as demonstrated by the lack of programs with coordinated interdisciplinary care, variability in long-term follow-up, and the absence of education and training. Research is needed to support the development and implementation of comprehensive pediatric oncology rehabilitation programs.

Microsurgical techniques in the treatment of breast cancer-related lymphedema: a systematic review of efficacy and patient outcomes

INTRODUCTION

Secondary lymphedema is the abnormal collection of lymphatic fluid within subcutaneous structures. Patients with lymphedema suffer a low quality of life. In our study, we aim to provide a systematic review of the current data on patient outcomes regarding breast cancer-related lymphedema (BCRL), and the most prevalent reconstructive techniques.

METHODS

A PubMed (MEDLINE) and Scopus literature search was performed in September 2020. Studies were screened based on inclusion/exclusion criteria. The protocol was registered at the International Prospective Register of Systematic Reviews (PROSPERO), and it was reported in line with the PRISMA statement (Preferred Reporting Items for Systematic Reviews and Meta-Analyses).

RESULTS

The search yielded 254 papers from 2010 to 2020. 67 were included in our study. Lymphaticovenous anastomosis (LVA)-a minimally invasive procedure diverting the lymph into the dermal venous drainage system-combined with postoperative bandaging and compression garments yields superior results with minimal donor site lymphedema morbidity. Vascularized lymph node transfer (VLNT)-another microsurgical technique, often combined with autologous free flap breast reconstruction-improves lymphedema and brachial plexus neuropathies, and reduces the risk of cellulitis. The combination of LVA and VLNT or with other methods maximizes their effectiveness. Vascularized lymph vessel transfer (VLVT) consists of harvesting certain lymph vessels, sparing the donor site's lymph nodes.

CONCLUSION

Together with integrated lymphedema therapy, proper staging, and appropriate selection of procedure, safe and efficient surgical techniques can be beneficial to many patients with BCRL.

Prospective Surveillance and Risk Reduction of Cancer Treatment-Related Lymphedema: Systematic Review and Meta-Analysis

PROBLEM IDENTIFICATION

Secondary lymphedema is a chronic condition that may result from cancer-related treatments. Evidence is emerging on prospective surveillance and risk reduction.

LITERATURE SEARCH

Databases were systematically searched through April 1, 2019, for comparative studies evaluating interventions aiming to prevent lymphedema in patients with cancer.

DATA EVALUATION

A random-effects model was used to perform meta-analysis, when appropriate.

SYNTHESIS

A total of 26 studies (4,095 patients) were included, with 23 providing data sufficient for meta-analysis. Surveillance programs increased the likelihood of detecting lymphedema. Physiotherapy, exercise programs, and delayed exercise reduced the incidence of lymphedema.

IMPLICATIONS FOR RESEARCH

Future research should standardize (a) evidence-based interventions to reduce the development of lymphedema and increase the likelihood of early detection and (b) outcome measures to build a body of evidence that leads to practice change.

Interventions for Breast Cancer-Related Lymphedema: Clinical Practice Guideline From the Academy of Oncologic Physical Therapy of APTA

A work group from the American Physical Therapy Association (APTA) Academy of Oncologic Physical Therapy developed a clinical practice guideline to aid clinicians in identifying interventions for people with breast cancer-related lymphedema, targeting volume reduction, beginning at breast cancer diagnosis and continuing through cancer treatments and survivorship. Following a systematic review of published studies and a structured appraisal process, recommendations were developed to guide physical therapists and other health care clinicians in their intervention selection. Overall, clinical practice recommendations were formulated based on the evidence for each intervention and were assigned a grade based on the strength of the evidence. The evidence for each specific intervention was synthesized and appraised by lymphedema stage, when the information was available. In an effort to make recommendations clinically applicable, they were presented by modality throughout the care trajectory. Methodology and research populations varied significantly across studies, and it will be important for future research to use standardized definitions for participant characteristics, diagnostic criteria, and interventions.

Self-Managed Surveillance for Breast Cancer-Related Upper Body Issues: A Feasibility and Reliability Study

BACKGROUND

Early identification of breast cancer-related upper body issues is important to enable timely physical therapist treatment.

OBJECTIVE

This study evaluated the feasibility and reliability of women performing self-managed prospective surveillance for upper body issues in the early postoperative phase as part of a hospital-based physical therapy program.

DESIGN

This was a prospective, single-site, single-group feasibility and reliability study.

METHODS

Presurgery arm circumference measurements were completed at home and at the hospital by participants and by a physical therapist. Instruction in self-measurement was provided using a video guide. After surgery, all circumference measurements were repeated along with self-assessment and therapist assessment for shoulder flexion and abduction active range of motion. Feasibility was determined by recruitment/retention rates and participant-reported ease of performing self-measurements (1 [very difficult] to 10 [very easy]). Reliability was determined as intrarater reliability, interrater reliability, and agreement.

RESULTS

Thirty-three women who were 53.4 (SD = 11.4) years old participated, with recruitment and retention rates of 79% and 94%, respectively. Participant-reported ease of measurement was 8.2 (SD = 2.2) before surgery and 8.0 (SD = 1.9) after surgery. The intrarater reliability and interrater reliability were excellent before surgery (intraclass correlation coefficient [ICC] ≥ 0.94; 95% confidence interval = 0.87-0.97) and after surgery (ICC ≥ 0.91; 95% confidence interval = 0.76-0.96). Agreement between self-assessed and therapist-assessed active shoulder flexion (κ = 0.79) and abduction (κ = 0.71) was good.

LIMITATIONS

Further testing is needed using a prospective design with a longer follow-up to determine whether self-managed prospective surveillance and timely treatment can hinder the development of chronic breast cancer-related upper body issues.

CONCLUSIONS

Self-measured arm circumference and shoulder range of motion are reliable, and their inclusion in a hospital-based program of prospective surveillance for upper body issues seems feasible. This approach may improve early detection and treatment.

The Who, What, Why, When, Where, and How of Team-Based Interdisciplinary Cancer Rehabilitation

OBJECTIVE

To review the key components necessary for successful application of rehabilitation principles to oncology survivors.

DATA SOURCES

Validated databases, including PubMed, MEDLINE, and Scopus.

CONCLUSION

Rehabilitation is an essential component of cancer care that addresses functional needs for oncology survivors and is best accomplished via an interdisciplinary team. Interdisciplinary care, provided by nursing, physiatry, rehabilitation therapy, and exercise physiology, are critical components for comprehensive intervention. Challenges exist in implementing services, but opportunity also exists within the post-acute care sector.

IMPLICATIONS FOR NURSING PRACTICE

Nurses play an important role in the screening, assessment, and treatment of cancer-related functional impairments.

Self-Measured Arm Circumference in Women With Breast Cancer Is Reliable and Valid

BACKGROUND

Prospective surveillance by physical therapists enables early detection and treatment of breast cancer-related lymphedema (BCRL). Strategies to increase access to prospective surveillance could reduce the burden of BCRL on patients and the health system. One potential solution is self-managed surveillance that does not require in-person assessment by a specialized physical therapist.

OBJECTIVE

The objective was to develop and test the reliability and validity of a written and video-supported protocol for women with breast cancer to self-measure arm circumference.

DESIGN

This was a cross-sectional reliability and validity study.

RESULTS

The intrarater reliability between CIRself_home and CIRself_lab and the interrater reliability between CIRself_lab and CIRther was high to excellent for both arms in both groups (intraclass correlation coefficient ≥0.86). VOLself_lab correlated strongly with VOLper (r ≥ 0.95), demonstrating excellent validity. Participants reported strong intention, self-efficacy, and positive attitude toward the performance of self-managed surveillance for BCRL, which was not perceived to increase worry about having or getting BCRL.

METHODS

Participants with (n = 20) and without (n = 21) BCRL completed self-measurement of arm circumference on both arms at home (CIRself_home) and at the lab (CIRself_lab) (intrarater reliability). The CIRself_lab was subsequently compared to measures performed by a specialized physical therapist (CIRther) (interrater reliability). To test validity, arm volume calculated from the self-measurements (VOLself_lab) was compared to perometry measurements (VOLper). Participants completed a questionnaire to assess attitudes for performing self-managed surveillance for BCRL.

LIMITATIONS

These findings need to be replicated in a clinical setting to confirm the reliability and acceptability of self-managed surveillance for BCRL among women newly diagnosed with breast cancer.

CONCLUSIONS

Self-measured arm circumference is reliable and valid among women with and without BCRL. Self-managed surveillance for BCRL can support self-efficacy without increasing anxiety.

Early surveillance is associated with less incidence and severity of breast cancer-related lymphedema compared with a traditional referral model of care

Background

Bioimpedance spectroscopy (BIS) has enabled the early identification of breast cancer‐related lymphedema. In this study, differences in health service metrics and in the incidence of breast cancer‐related lymphedema are evaluated in an early surveillance model of care compared with a traditional referral model of care.

Methods

In a retrospective analysis of data from 753 women who underwent BIS measures between January 1, 2007 and December 31, 2016, 188 women were assigned to the “early surveillance” group if they began lymphedema monitoring presurgery (n = 121) or within 90 days postsurgery (n = 67), and 285 women were assigned to the “traditional referral” group if they began monitoring after 90 days postsurgery. Health service metrics were calculated as the time to the first BIS measure after 90 days postsurgery, the median follow‐up, and the number of health care visits. Lymphedema was diagnosed based on BIS measures.

Results

Women in the early surveillance group received lymphedema care significantly earlier than those in the traditional referral group. However, there was no difference in the number of visits per year to the clinic between groups. Significantly more women in the traditional referral group were diagnosed with clinical lymphedema (stage I‐III, 39 % vs 14%; P < .001) and with greater severity (stage II‐III, 24%) compared with those in the early surveillance group (4%).

Conclusions

The current findings support the adoption of an early prospective surveillance model of care using BIS for the early detection and management of breast cancer–related lymphedema.

The differences in health service metrics and in the incidence of breast cancer–related lymphedema are evaluated in an early surveillance model of care compared with a traditional referral model of care. The findings support the adoption of an early prospective surveillance model of care using bioimpedance spectroscopy for the early detection and management of breast cancer–related lymphedema.

Prospective surveillance and targeted physiotherapy for arm morbidity after breast cancer surgery: a pilot randomized controlled trial

OBJECTIVE

To evaluate prospective surveillance and targeted physiotherapy (PSTP) compared to education (EDU) on the prevalence of arm morbidity and describe the associated program cost.

DESIGN

Pilot randomized single-blinded controlled trial.

SETTING

Urban with assessments and treatment delivered in hospitals.

PARTICIPANTS

Women scheduled for breast cancer surgery.

INTERVENTIONS

Participants were randomly assigned (1:1) to PSTP ( n = 21) or EDU ( n = 20) and assessed presurgery and 12 months postsurgery. All participants received usual care, namely, preoperative education and provision of an education booklet with postsurgical exercises. The PSTP group was monitored for arm morbidity every three months and referred for physiotherapy if arm morbidity was identified. The EDU group received three education sessions on nutrition, stress and fatigue management.

MAIN OUTCOME MEASURES

Arm morbidity was based on changes in the surgical arm(s) from presurgery in four domains: (1) shoulder range of motion, (2) strength, (3) volume, and (4) upper body function. Complex arm morbidity indicated ≥2 domains impaired. Second, the cost of the PSTP program was described.

RESULTS

At 12 months, 18 (49%) participants (10 PSTP and 8 EDU) had arm morbidity, with EDU participants presenting more complex arm morbidity compared to PSTP participants. PSTP participants attended 4.4 of 5 assessments with 90% retention. The PSTP program cost was $150 covered by the Health Care Provider and the Patient Out-of-Pocket Travel cost was CAN$40.

CONCLUSION

Our results suggest that PSTP is feasible among women with breast cancer for early identification of arm morbidity. A larger study is needed to determine the cost and effectiveness benefits.

Changes in volume and incidence of lymphedema during and after treatment with docetaxel, doxorubicin, and cyclophosphamide (TAC) in patients with breast cancer

Purposes

The purposes of this study were to investigate the incidence of lymphedema in patients with breast cancer during and after adjuvant treatment with docetaxel, doxorubicin, and cyclophosphamide (TAC), to identify predictors for development of lymphedema, and to describe consequences in daily life in relation to lymphedema.

Methods

This is a prospective study with measurements before chemotherapy (T0), during chemotherapy before cycle 2 (T1), cycle 4 (T2), and 1 month after completion of treatment (T3). Volume change was monitored using tape measurements. Lymphedema was defined as ≥ 10% volume difference. Linear mixed-effect models were estimated to analyze differences in arm volume and consequences in daily life (total score and domain scores of the Lymph-International Classification of Functioning (ICF) questionnaire) over time and to identify treatment and patient characteristics as predictors for changes in volume.

Results

Forty-eight patients completed all measurements. Volume did not change during TAC treatment. One month after treatment, volume was significantly increased compared to T0-T2, and 12 patients (25%) had developed lymphedema. Axillary lymph node dissection was associated with lymphedema (ES 2.9, 95% CI 0.02–5.7; p < 0.05). In patients with and without lymphedema, 1 month after completion (T3), the Lymph-ICF questionnaire showed significant limitations in physical function compared to T0-T2. In patients with lymphedema at T3, a significant association between volume and total score on the Lymph-ICF questionnaire on physical function and mobility activities was observed.

Conclusions

One month after treatment in 12 patients (25%), volume difference increased over 10%. Axillary lymph node dissection was predictive for development of lymphedema. All patients, but more patients with lymphedema, perceived difficulties in activities in daily life after treatment.
