Incidence of lymphedema related to various cancers.

Cancer-related lymphedema (CRL) lacks internationally accepted definition and diagnostic criteria. The accurate incidence of CRL is therefore a challenge and the condition is likely underreported. Patients treated for cancer can develop CRL as a result of surgery, chemotherapy, and/or radiotherapy, which can lead to considerable psychosocial and physical morbidity, and decreased quality of life. Determining CRL incidence is crucial to inform care access and resource allocation, to best support patients affected by this lifelong condition. This review aimed to provide the latest CRL incidence estimates. Using four core databases (MEDLINE, Embase, Web of Science Core Collection, Cochrane Library), a literature search was performed to capture publications dated between 2015 and 2023. A total of 48 articles (33 prospective studies, 15 systematic reviews) met inclusion criteria, providing a sample size of 234,079 cancer patients. Findings revealed CRL incidence across cancer types varied, reported 2-74% in breast, 8-45% in gynecological and urological, 71-90% in head and neck and 2-29% in melanoma cancers. CRL incidence varied between 3 and 21% in preventative lymphedema surgery patients. Projected increases in cancer incidence and improved survival rates are expected to further escalate CRL incidence. Healthcare systems and professionals alike must therefore prepare to meet the growing needs of CRL patients.

Segmentation of Arm Ultrasound Images in Breast Cancer-Related Lymphedema: A Database and Deep Learning Algorithm.

OBJECTIVE: Breast cancer treatment often causes the removal of or damage to lymph nodes of the patient's lymphatic drainage system. This side effect is the origin of Breast Cancer-Related Lymphedema (BCRL), referring to a noticeable increase in excess arm volume. Ultrasound imaging is a preferred modality for the diagnosis and progression monitoring of BCRL because of its low cost, safety, and portability. As the affected and unaffected arms look similar in B-mode ultrasound images, the thickness of the skin, subcutaneous fat, and muscle have been shown to be important biomarkers for this task. The segmentation masks are also helpful in monitoring the longitudinal changes in morphology and mechanical properties of tissue layers. METHODS: For the first time, a publicly available ultrasound dataset containing the Radio-Frequency (RF) data of 39 subjects and manual segmentation masks by two experts, are provided. Inter- and intra-observer reproducibility studies performed on the segmentation maps show a high Dice Score Coefficient (DSC) of 0.94±0.08 and 0.92±0.06, respectively. Gated Shape Convolutional Neural Network (GSCNN) is modified for precise automatic segmentation of tissue layers, and its generalization performance is improved by the CutMix augmentation strategy. RESULTS: We got an average DSC of 0.87±0.11 on the test set, which confirms the high performance of the method. CONCLUSION: Automatic segmentation can pave the way for convenient and accessible staging of BCRL, and our dataset can facilitate development and validation of those methods. SIGNIFICANCE: Timely diagnosis and treatment of BCRL have crucial importance in preventing irreversible damage.

Update to the Canadian clinical practice guideline for best-practice management of breast cancer-related lymphedema: study protocol.

BACKGROUND: One of the more frequent complications following treatment for breast cancer, lymphedema is a substantial swelling of the arm, breast and chest wall that occurs on the side where lymph nodes were removed. The aim of this work is to update recommendations on the prevention, diagnosis and management of lymphedema related to breast cancer. METHODS: We present the protocol for an update of the 2001 clinical practice guideline on lymphedema from the Steering Committee for Clinical Practice Guidelines for the Care and Treatment of Breast Cancer. We will use a patient-oriented research approach with a focus on self-management and the positive health model to inform the updated guideline development. The methods proposed will be undertaken with consideration of the standards outlined in the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. The literature will be appraised by evaluating existing guidelines from other countries, the evidence from systematic reviews and meta-analyses and direct evidence from clinical studies. We will manage competing interests according to Guidelines International Network principles. Recommendations will be presented using an actionable statement format and will be linked to the level of evidence along with any relevant considerations used in formulation. A draft of the guideline will be produced by the steering committee then sent out to international experts and stakeholder groups for feedback. INTERPRETATION: The primary benefit of this clinical guideline will be to improve the quality of care of women with breast cancer-related lymphedema. Findings will be disseminated at national and international conferences and through webinars and educational videos hosted on the websites of the supporting organizations.

Feasibility of a Pilot Randomized Controlled Trial Examining a Multidimensional Intervention in Women with Gynecological Cancer at Risk of Lymphedema.

There is limited knowledge on non-invasive lymphedema risk-reduction strategies for women with gynecological cancer. Understanding factors influencing the feasibility of randomized controlled trials (RCTs) can guide future research. Our objectives are to report on the design and feasibility of a pilot RCT examining a tailored multidimensional intervention in women treated for gynecological cancer at risk of lymphedema and to explore the preliminary effectiveness of the intervention on lymphedema incidence at 12 months. In this pilot single-blinded, parallel-group, multi-centre RCT, women with newly diagnosed gynecological cancer were randomized to receive post-operative compression stockings and individualized exercise education (intervention group: IG) or education on lymphedema risk-reduction alone (control group: CG). Rates of recruitment, retention and assessment completion were recorded. Intervention safety and feasibility were tracked by monitoring adverse events and adherence. Clinical outcomes were evaluated over 12 months: presence of lymphedema, circumferential and volume measures, body composition and quality of life. Fifty-one women were recruited and 36 received the assigned intervention. Rates of recruitment and 12-month retention were 47% and 78%, respectively. Two participants experienced post-operative cellulitis, prior to intervention delivery. At three and six months post-operatively, 67% and 63% of the IG used compression ≥42 h/week, while 56% engaged in ≥150 weekly minutes of moderate-vigorous exercise. The cumulative incidence of lymphedema at 12 months was 31% in the CG and 31.9% in the IG (p = 0.88). In affected participants, lymphedema developed after a median time of 3.2 months (range, 2.7-5.9) in the CG vs. 8.8 months (range, 2.9-11.8) in the IG. Conducting research trials exploring lymphedema risk-reduction strategies in gynecological cancer is feasible but challenging. A tailored intervention of compression and exercise is safe and feasible in this population and may delay the onset of lymphedema. Further research is warranted to establish the role of these strategies in reducing the risk of lymphedema for the gynecological cancer population.

Examining Obesity in Lymphedema: A Retrospective Study of 178 New Patients with Suspected Lymphedema at a Canadian Hospital-Based Clinic.

Purpose: Physiotherapists have an important role to play in the early detection and treatment of lymphedema, a chronic inflammatory condition characterized by excess interstitial protein-rich fluid, which is estimated to affect more than one million Canadians. Obesity has been identified both as an important cause of and as a risk factor for developing lymphedema of various aetiologies. Little is currently known about obesity in Canadians affected by lymphedema. The objective of this study was to report on the prevalence of overweight and obesity in a Canadian lymphedema clinic population and the relationships among BMI; demographic, medical, and lymphedema characteristics; and cellulitis history. Method: We conducted a retrospective electronic record review of the clinical data collected from new patients evaluated for suspected lymphedema at a specialized Canadian hospital-based clinic over a 2-year period. We used descriptive analyses to characterize the sample and one-way analysis of variance and χ2 tests for comparative analyses. Results: Of the 178 patients whose records were reviewed, 36.5% were classified as overweight and 39.3% as obese. Patients with non-cancer diagnoses had a higher mean BMI than those with cancer-related diagnoses (p < 0.001). A higher BMI was associated with a longer time since lymphedema onset (p < 0.001), bilateral lymphedema (p = 0.010), and history of cellulitis (p < 0.001). Conclusions: Obesity is prevalent in the Canadian population with lymphedema and is associated with delayed referral and increased cellulitis rates. Early detection and tailored management strategies are needed to address obesity in patients with lymphedema and the complexities associated with these two related conditions.

Objectif : les physiothérapeutes ont un rôle important à jouer pour favoriser le dépistage précoce et le traitement du lymphœdème, un trouble inflammatoire chronique caractérisé par un excès de liquide interstitiel riche en protéines qui toucherait plus d'un million de Canadiens. L'obésité est considérée à la fois comme une cause importante et un facteur de risque de lymphœdème de diverses étiologies. On ne sait pas grand-chose sur l'obésité des Canadiens atteints de lymphœdème. La présente étude visait à rendre compte de la prévalence de surpoids et d'obésité dans la population de la clinique canadienne de lymphœdème des chercheurs et des liens entre l'indice de masse corporelle (IMC), les données démographiques, les caractéristiques médicales et lymphœdémateuses et les antécédents de cellulite. Méthodologie : les chercheurs ont procédé à une analyse rétrospective des données cliniques tirées de dossiers électroniques de nouveaux patients évalués à cause d'une présomption de lymphœdème dans une clinique hospitalière canadienne spécialisée, et ce, sur une période de deux ans. Ils ont utilisé des analyses descriptives pour caractériser l'échantillon et procédé aux évaluations comparatives à l'aide des analyses de variance unidirectionnelle et des tests du chi carré. Résultats : des 178 patients dont le dossier a été examiné, 36,5 % étaient classés comme en surpoids et 39,3 % comme obèses. Les patients dont le diagnostic n'était pas lié au cancer présentaient un IMC moyen plus élevé que ceux dont le diagnostic était lié au cancer (p < 0,001). Un IMC plus élevé chez les patients s'associait à une période plus longue depuis l'apparition de lymphœdème (p < 0,001), à un lymphœdème bilatéral (p = 0,010) et à des antécédents de cellulite (p < 0,001). Conclusion : L'obésité est prévalente dans la population canadienne atteinte de lymphœdème et s'associe à un délai avant l'envoi en consultation et à une augmentation des cellulites. Un dépistage précoce et des stratégies de prise en charge adaptées s'imposent pour agir sur l'obésité chez les patients atteints de lymphœdème et sur les complexités liées à ces deux troubles connexes.

Cancer-associated secondary lymphoedema.

Lymphoedema is an oedematous condition with a specific and complex tissue biology. In the clinical context of cancer, the pathogenesis of lymphoedema ensues most typically from the modalities employed to stage and treat the cancer (in particular, surgery and radiotherapy). Despite advances in cancer treatment, lifelong lymphoedema (limb swelling and the accompanying chronic inflammatory processes) affects approximately one in seven individuals treated for cancer, although estimates of lymphoedema prevalence following cancer treatment vary widely depending upon the diagnostic criteria used and the duration of follow-up. The natural history of cancer-associated lymphoedema is defined by increasing limb girth, fibrosis, inflammation, abnormal fat deposition and eventual marked cutaneous pathology, which also increases the risk of recurrent skin infections. Lymphoedema can substantially affect the daily quality of life of patients, as, in addition to aesthetic concerns, it can cause discomfort and affect the ability to carry out daily tasks. Clinical diagnosis is dependent on comparison of the affected region with the equivalent region on the unaffected side and, if available, with pre-surgical measurements. Surveillance is indicated in this high-risk population to facilitate disease detection at the early stages, when therapeutic interventions are most effective. Treatment modalities include conservative physical strategies that feature complex decongestive therapy (including compression garments) and intermittent pneumatic compression, as well as an emerging spectrum of surgical interventions, including liposuction for late-stage disease. The future application of pharmacological and microsurgical therapeutics for cancer-associated lymphoedema holds great promise.

Of dilemmas and tensions: a qualitative study of palliative care physicians' positions regarding voluntary active euthanasia in Quebec, Canada.

OBJECTIVES: In 2015, the Province of Quebec, Canada passed a law that allowed voluntary active euthanasia (VAE). Palliative care stakeholders in Canada have been largely opposed to euthanasia, yet there is little research about their views. The research question guiding this study was the following: How do palliative care physicians in Quebec position themselves regarding the practice of VAE in the context of the new provincial legislation? METHODS: We used interpretive description, an inductive methodology to answer research questions about clinical practice. A total of 18 palliative care physicians participated in semistructured interviews at two university-affiliated hospitals in Quebec. RESULTS: Participants positioned themselves in opposition to euthanasia. Their justifications were framed within their professional commitment to not hasten death, which sat in tension with the value of patients' autonomy to choose how to die. Participants described VAE as unacceptable if it impeded opportunities to evaluate and alleviate suffering. Further, they contested government rhetoric that positioned VAE as a way to improve end-of-life care. Participants felt that VAE would diminish the potential of palliative care to relieve suffering. Dilemmas were apparent in their narratives, about reconciling respect for patient autonomy with broader palliative care values, and the value of accompanying and not abandoning patients who make requests for VAE while being committed to neither prolonging nor hastening death. CONCLUSIONS: This study provides insight into nuanced positions of experienced palliative care physicians in Quebec and confirms expected tensions between an important stakeholder and the practice of VAE as guided by the new legislation.

Assessment of Mechanical Properties of Tissue in Breast Cancer-Related Lymphedema Using Ultrasound Elastography.

Breast cancer-related lymphedema is a consequence of a malfunctioning lymphatic drainage system resulting from surgery or some other form of treatment. In the initial stages, minor and reversible increases in the fluid volume of the arm are evident. As the stages progress over time, the underlying pathophysiology dramatically changes with an irreversible increase in arm volume most likely due to a chronic local inflammation leading to adipose tissue hypertrophy and fibrosis. Clinicians have subjective ways to stage the degree and severity such as the pitting test which entails manually comparing the elasticity of the affected and unaffected arms. Several imaging modalities can be used but ultrasound appears to be the most preferred because it is affordable, safe, and portable. Unfortunately, ultrasonography is not typically used for staging lymphedema, because the appearance of the affected and unaffected arms is similar in B-mode ultrasound images. However, novel ultrasound techniques have emerged, such as elastography, which may be able to identify changes in mechanical properties of the tissue related to detection and staging of lymphedema. This paper presents a novel technique to compare the mechanical properties of the affected and unaffected arms using quasi-static ultrasound elastography to provide an objective alternative to the current subjective assessment. Elastography is based on time delay estimation (TDE) from ultrasound images to infer displacement and mechanical properties of the tissue. We further introduce a novel method for TDE by incorporating higher order derivatives of the ultrasound data into a cost function and propose a novel optimization approach to efficiently minimize the cost function. This method works reliably with our challenging patient data. We collected radio frequency ultrasound data from both arms of seven patients with stage 2 lymphedema, at six different locations in each arm. The ratio of strain in skin, subcutaneous fat, and skeletal muscle divided by strain in the standoff gel pad was calculated in the unaffected and affected arms. The p -values using a Wilcoxon sign-rank test for the skin, subcutaneous fat, and skeletal muscle were 1.24×10-5 , 1.77×10-8 , and 8.11×10-7 respectively, showing differences between the unaffected and affected arms with a very high level of significance.

Self-Management Strategies for Malignant Lymphedema: A Case Report with 1-Year and 4-Year Follow-Up Data.

Purpose: Malignant lymphedema is an accumulation of interstitial fluid caused by tumour infiltration or compression of lymphatic vessels. Our objective is to describe self-management strategies for malignant lymphedema using a case report. Client Description: A 50-year-old woman with advanced breast cancer was referred to our centre with a 3-month history of unexplained left-arm edema, subsequently diagnosed as malignant lymphedema caused by tumour compression of the axillary lymph nodes. Intervention: She undertook a physiotherapist-guided, modified lymphedema treatment programme, with self-management interventions including self-bandaging and exercise. Limb volumes and leisure exercise levels were measured over a 1-year period. Data were collected from her follow-up visit 4 years post-diagnosis of lymphedema. Measures and Outcome: Within the first month, the patient's excess limb volume reduced from 26.8% to 5.9% and, 1 year later, remained stable at 3%. Over time, her exercise levels increased (1-year follow-up: 33.5 MET-hours per week). At 4 years, her excess limb volume was 9.7%, and exercise levels were at 36 MET-hours per week. Implications: A woman with moderate malignant arm lymphedema caused by advanced breast cancer successfully adhered to a guided self-management programme and benefited from reduced swelling and improved self-reported physical function in the long term. This case provides oncology health professionals with knowledge about self-management options for malignant lymphedema.

Objectif : le lymphœdème malin désigne une accumulation de liquide interstitiel causé par l'infiltration d'une tumeur ou la compression des vaisseaux lymphatiques. Les auteurs utilisent un rapport de cas pour décrire des stratégies d'autogestion du lymphœdème malin. Description de la cliente : une femme de 50 ans atteinte d'un cancer du sein avancé a été dirigée vers le centre des auteurs parce qu'elle présentait un œdème inexpliqué du bras gauche depuis trois mois. Cet œdème a ensuite été diagnostiqué comme un lymphœdème causé par la compression d'une tumeur sur les ganglions axillaires. Intervention : la patiente a entrepris un traitement modifié du lymphœdème, orienté par des physiothérapeutes et comportant des interventions d'autogestion, y compris les changements de bandages et des exercices. Les auteurs ont mesuré le volume des membres et le taux d'exercices de loisir sur une période d'un an. Ils ont recueilli les données jusqu'au rendez-vous de suivi quatre ans après le diagnostic de lymphœdème. Mesures et résultats : au cours du premier mois, le volume excédentaire du membre de la patiente est passé de 26,8 % à 5,9 % et était demeuré stable un an plus tard, à 3 %. Au fil du temps le taux d'exercice de la patiente a augmenté (suivi d'un an : 33,5 équivalents métaboliques de l'effort [MET]-heures par semaine). Au bout de quatre ans, le volume excédentaire de son bras était de 9,7 %, et son taux d'exercice, de 36 MET-heures par semaine. Conséquences : une femme présentant un lymphœdème malin modéré du bras causé par un cancer du sein avancé a suivi un programme d'autogestion orienté et observé une diminution de son œdème et une amélioration autodéclarée de sa fonction physique à long terme. Ce cas fournit aux professionnels en oncologie de des connaissances sur les possibilités d'autogestion du lymphœdème malin.

Comparisons Between Cancer-Related and Noncancer-Related Lymphedema: An Overview of New Patients Referred to a Specialized Hospital-Based Center in Canada.

BACKGROUND: Lymphedema is an irreversible inflammatory condition caused by accumulated lymph fluid and is associated with chronic swelling and increased risk of cellulitis. Our objectives were to: (1) describe the patient population referred to a Canadian lymphedema center and (2) compare lymphedema characteristics between patients with cancer and patients with noncancer diagnoses. METHODS AND RESULTS: A retrospective cohort study was conducted of new patients referred for suspected lymphedema to a hospital-based center over a 2-year period. The mean age of the patients (n = 429) was 61.4 years; 85% were female and 81% had a history of cancer. Lymphedema characteristics were primary (7%) versus secondary (92%); upper body (51%) versus lower body (45%); unilateral (74%) versus bilateral (25%); and history of cellulitis (22%). Patients with noncancer diagnoses (n = 82) were more likely than patients with cancer diagnoses (n = 347) to have a history of cellulitis (44% vs. 17%), to have bilateral (61% vs. 16%) and lower limb (89% vs. 37%) lymphedema, and to experience a long delay between symptom onset and referral (14.0 vs. 3.5 years) (p < 0.001). CONCLUSION: Most patients referred to our lymphedema center were female with a history of cancer. However, patients with noncancer diagnoses were more likely to have bilateral lower body lymphedema with an important history of cellulitis; this subgroup is at great risk of missed and delayed diagnoses in the medical setting and of experiencing long-term issues with mobility, recurrent hospitalizations, and poor quality of life.

A longitudinal analysis of chronic arm morbidity following breast cancer surgery.

Arm morbidity (AM) arising from breast cancer (BC) treatment can detrimentally impact quality of life; often limiting a survivor's ability to participate in valued activities. The present study explored (a) the developmental time course of AM [restricted range of motion (ROM), pain, and arm volume changes], negative affect, and perceived disability in the immediate years post-surgery, and (b) the mediating role of perceived disability on the relationship between AM and negative affect over time. In this 5-year longitudinal study, BC survivors from four Canadian oncology clinics (n = 431) completed five annual clinical assessments, where differences in ROM (shoulder abduction, external rotation) and arm volume between the affected and non-affected arm were measured. The profile of mood states (POMS), disability of arm, shoulder, hand, and McGill Pain Questionnaire-Short form were completed. Results from general linear modeling showed that AM, negative affect, and perceived disability were greatest 1-year post-surgery, declined, and with the exception of arm volume changes, were significantly lower 5 years later. Negative affect was significantly associated with restrictions in shoulder abduction and external rotation (average r = -0.15; p < 0.05) and present arm pain (average r = 0.28, p < 0.01) at most assessments. The mediating role of perceived disability on the relationship between AM and negative affect was statistically significant in a majority of assessments. Perceived disability is the underlying factor driving the relationship between AM and mood disturbance over time. Rehabilitative therapy to improve survivors' functional well-being might mitigate the negative impacts of AM on emotional health.

Loss, adaptation and new directions: The impact of arm morbidity on leisure activities following breast cancer.

The impact of arm morbidity on leisure and quality of life is an understudied area in cancer survivorship. The purpose of this study was to qualitatively describe the impact of breast cancer-related arm morbidity on leisure participation in Canadian women. A grounded theory approach was used to generate thematic categories and a model. Drawing on participants from a larger cohort study (n = 740), 40 women with arm morbidity symptoms were purposively sampled and interviewed. Three themes emerged: a sense of loss, adapting participation, and new directions. Women with arm morbidity may experience an abrupt loss of previously enjoyed leisure activities and engage in a process of adapting to discover new meanings and directions. Comprehensive, person-centred cancer survivorship programs may assist with adaptation to arm morbidity.

Accuracy and usefulness of the Palliative Prognostic Index in a community setting.

PURPOSE: In a community setting characterised by scarce inpatient palliative care resources, a precise prognosis could help determine which patients should be prioritised for end-of-life admission. AIM: The aim of this study was to assess the validity of the Palliative Prognostic Index (PPI) and to determine whether it is a helpful tool for nurses to administer as part of the admission protocol in the palliative care service of a community hospital. RESULTS: The PPI was a moderately accurate prognostic tool when assessing the frequency of 14-day overstay; 81% of patients died within 14 days of their expected prognosis. Based on sensitivity and specificity, the accuracy of the prognoses was acceptable for the 6-week prognosis group (80%), and poor for the 3-week prognostic group (53%). The tool was easy to administer by the admission nurse receiving referrals. CONCLUSION: A nurse-administered and minimally-invasive prognostic tool was helpful in this context.

Breast cancer-related lymphedema: a randomized controlled pilot and feasibility study.

OBJECTIVE: Chronic lymphedema occurs frequently in breast cancer patients and is associated with significant morbidity and reduced quality-of-life. In this pilot study, the authors (1) addressed whether conducting a larger randomized controlled trial of aqua lymphatic therapy (ALT) would be feasible and (2) estimated the extent to which ALT combined with home-based exercise compared with home-based exercise alone would reduce arm disability in patients with breast cancer-related lymphedema. DESIGN: Twenty-five women with breast cancer-related lymphedema were randomized to either ALT in addition to a home land-based exercise program (ALT group; n = 13) or to a home land-based exercise program alone (control group; n = 12). The participants were evaluated before and after a 12-wk intervention period composed of weekly pool exercise sessions. Main outcome measures were arm volume, arm disability, pain, and quality-of-life. RESULTS: At follow-up, there was no statistical difference between the control and ALT groups in any of the outcomes, except for present pain intensity. At the end of the study period, there was no change in the lymphedematous limb volume in either group. Grip strength was improved in both groups. Only the ALT group showed a statistically significant difference with a reduction in pain intensity score and arm disability. Furthermore, quality-of-life significantly improved only in the ALT group. CONCLUSIONS: Conducting a larger randomized controlled trial would be feasible. In comparison with the beginning of the intervention, the participants in the ALT group showed significant beneficial changes after 12 wks of treatment, whereas the control group did not improve. ALT did not make the lymphedema volume worse and therefore may serve as a safe alternative to land-based treatments of breast cancer-related lymphedema.

A lymphedema self-management programme: report on 30 cases.

PURPOSE: Compression therapy is the most important element in the treatment and long-term management of moderate and severe lymphedema, but it is not universally accessible in Canada. For those unable to access private lymphedema treatment, physiotherapists at the McGill University Health Centre (MUHC) Lymphedema Clinic began teaching patients and caregivers how to use compression bandages safely and effectively. METHODS: A retrospective chart review was combined with structured telephone or in-person interviews with 30 people who had attended a self-bandaging clinic in the MUHC Lymphedema Clinic between 2011 and 2012. Patients were monitored weekly until limb volume plateaued, and a compression garment was then fitted for ongoing maintenance. Monthly or quarterly surveillance continued for 1 year. Follow-up interviews were conducted 3 to 18 months after patients had received their garments. RESULTS: The majority of participants had moderate to severe lymphedema; all achieved reduction of edema in the range of 48% to 92%. More than three-quarters of participants reported a global rate of change (GRC) of ≥80%. Themes derived from the interviews included the importance of bandaging, the feeling of being in control, and difficulties with compression garments. Participants spontaneously expressed satisfaction about having tools to manage their condition themselves. CONCLUSION: For selected patients with lymphedema, a self-bandaging programme can be a route to lymphedema reduction, independence, and self-efficacy.

Objectif : La compressothérapie est l'élément le plus important dans le traitement et la gestion à long terme du lymphœdème modéré à grave, mais elle n'est pas universellement accessible au Canada. Pour ceux qui n'ont pas accès à un traitement privé contre le lymphœdème, la Clinique de lymphœdème du Centre universitaire de santé McGill (CUSM) a commencé à enseigner aux patients et aux fournisseurs de soins la façon d'utiliser les bandages de compression de façon sûre et efficace. Méthodes : Un examen rétrospectif des dossiers a été combiné à des entrevues téléphoniques structurées auprès de 30 personnes qui avaient assisté, en 2011 et en 2012, à l'atelier sur l'exécution de bandages de la Clinique de traitement du lymphœdème du CUSM. Les patients ont fait l'objet d'un suivi hebdomadaire jusqu'à ce que le volume de leur membre atteigne un plateau; un vêtement de compression a ensuite été ajusté à leur membre pour l'entretien continu. La surveillance mensuelle ou trimestrielle s'est poursuivie pendant un an. De 3 à 18 mois après que les patients aient reçu leur vêtement de compression, on a mené des entrevues de suivi pour le présent rapport. Résultats : La majorité des participants souffraient de lymphœdème modéré à grave; ils ont tous réussi à réduire l'œdème dans une mesure de 48% à 92%. Plus des trois quarts des participants ont signalé un taux global de changement (TGC) ≥80%. Les thèmes tirés des entrevues étaient notamment l'importance du bandage, le sentiment de maîtrise, et les difficultés posées par les vêtements de compression. Les participants ont exprimé spontanément qu'ils étaient satisfaits de disposer d'outils pour gérer eux-mêmes leur état. Conclusion : Chez certains patients souffrant de lymphœdème, un programme leur permettant d'effectuer eux-mêmes leurs bandages peut favoriser la réduction du lymphœdème, l'autonomie et l'autoefficacité.

Determining the precision of dual energy x-ray absorptiometry and bioelectric impedance spectroscopy in the assessment of breast cancer-related lymphedema.

BACKGROUND: The composition of breast cancer-related lymphedema (BCRL) has been shown to evolve from the initial accumulation of fluid to the development of fibrotic lesions and abnormal fat deposition. Therefore, precise and reliable assessments of BCRL are required to develop accurate staging and management. Although dual energy x-ray absorptiometry (DXA) and bioelectric impedance spectroscopy (BIS) have been used to assess BCRL, no study has evaluated the precision of these two modalities in the same cohort. METHODS AND RESULTS: We determined the precision of DXA and BIS in lymphedematous (LE) and nonaffected (NA) arms of 24 women with Stage II unilateral BCRL. Precision was calculated from the results of paired bilateral arm measurements obtained from DXA scans measuring fat, lean, and bone mineral masses, BIS measuring extracellular fluid (ECF) and total fluid volume, and circumferential tape measurements (CM) of the arms to calculate the anatomic volume. Precision error was expressed as the root mean square (RMS) of the coefficients of variation (%CV) and standard deviations (SD). RESULTS: The precisions of DXA and BIS varied from 1.16% (DXA measurements of LE arm total volume) to 1.86% (BIS LE arm total fluid volume) and from 0.95% (DXA lean mass of NA arm) to 1.72% (DXA BMC of NA arm). Precision of CM measures of arm volume were 1.71% CV for LE arm and 2.51% CV for NA arm. The fat and lean masses of the LE arm exceeded the NA arm by about 15% (p<0.0001). ECF and total fluid volume of LE arm was 22.6% and 19% greater than the NA arm (p<0.0001), respectively. CONCLUSION: For BCRL, these findings suggest that DXA and BIS are two measurement instruments that provide acceptable levels of precision for the measurement of arm lean mass, fat mass and ECF volume, respectively.

Do breast cancer survivors' post-surgery difficulties with recreational activities persist over time?

INTRODUCTION: Most longitudinal breast cancer studies have found that treatment-related sequelae such as arm morbidity [lymphedema, pain, and range of motion (ROM) restrictions] can have a significant impact on quality of life. In a previous study, we found that at 6-12 months after breast cancer surgery, 49% of participants had difficulties engaging in recreational activities and that arm morbidity significantly predicted difficulties with participation in recreation. METHODS: A longitudinal national study employing clinical assessments and survey methods followed 178 women over 43 months (3.6 years) to assess issues related to arm morbidity post-breast cancer surgery. Hierarchical multiple regression analyses were conducted to identify which variables were predictive of recreational difficulties experienced by women 8 and 43 months post-surgery. RESULTS: Between 8 months (T1) and 43 months (T2) post-breast cancer surgery, women demonstrated slight increases in lymphedema. Conversely, a significant decrease was observed in the number of ROM restrictions and pain when using the arm. Despite the overall improvements in arm morbidity, some women continued to report moderate pain and ROM restrictions. The two arm morbidity factors were found to be statistically significant (p < 0.001) predictors of recreational difficulties at both 8 and 43 months post-surgery, with pain accounting for the greatest proportion of variance. DISCUSSION/CONCLUSION: Pain and ROM restrictions were the only significant predictors of recreational difficulties during the first 3.6 years after breast cancer surgery. Specifically, women who still experience pain years after breast cancer surgery report difficulties in their recreational pursuits. IMPLICATIONS FOR CANCER SURVIVORS: Pain and ROM restrictions may prohibit participation in recreational activity and targeted intervention should be sought.

Predictors of arm morbidity following breast cancer surgery.

OBJECTIVE: Arm morbidity post-breast cancer surgery is increasingly being recognized as a chronic problem for some women following breast cancer surgery. The purpose of this study was to examine demographic, disease, and treatment-related predictors of a comprehensive array of chronic arm morbidity (pain, lymphedema, functional disability, and range of motion) post-breast cancer surgery. METHODS: Women (n=316) with a non-metastatic primary diagnosis of breast cancer were accrued from cancer centers in four Canadian cities. Patients completed a clinical assessment and measures of arm morbidity at 6-12 months post-breast cancer surgery. The independent variables in the MANOVA to predict arm morbidity included: Lymph node management type, number of axillary nodes dissected, type of surgery, disease stage, presence of post-operative infection, radiation to the axilla, body mass index (BMI), assessment time post-surgery, education, and partner status. RESULTS: Pain was significantly predicted by axillary lymph node management, lack of a partner, and post-operative infection; lymphedema by axillary lymph node management, number of axillary nodes dissected, radiation to the axilla, and having a modified radical mastectomy; functional disability by post-operative infection and high BMI; and restricted external rotation by axillary lymph node management, low educational attainment, and advanced disease. CONCLUSION: Comprehensive behavioral management and rehabilitation programs are needed to treat arm morbidity following breast cancer surgery. These programs should address the full scope of symptoms and associated psychosocial and functional sequelae.

The impact of breast cancer among Canadian women: disability and productivity.

Each year over 20,000 Canadian women are diagnosed with breast cancer. Many breast cancer survivors anticipate a considerable number of years of potential participation in the paid labour market, therefore, the link between breast cancer survivorship and productivity deserves serious consideration. The hypothesis guiding this study is that arm morbidities such as lymphedema, pain, and range of motion limitations are important explanatory variables in survivors' loss of productivity. The study draws from a larger longitudinal research project involving over 600 breast cancer survivors in four geographical locations across Canada. The study's regression results indicate that, after adjusting for fatigue, breast cancer stage, and geographical location, survivors with range of motion limitations and arm pain are more than two and half times as likely to lose some productivity capacity as compared to counterparts with no arm morbidity. The findings make a compelling argument for the necessity of adequate rehabilitation programs delivered at crucial times in breast cancer survivors' recovery. The study's unexpected finding that geographical location is a highly significant predictor of changes in productivity among breast cancer survivors is interpreted as a factor of the regulatory framework governing employment relationships in the four different jurisdictions.

Predicting recreational difficulties and decreased leisure activities in women 6-12 months post breast cancer surgery.

INTRODUCTION: A Canadian research team is conducting a multi-centered, non-interventional national study with the objective of charting the course of arm morbidity after breast cancer surgery. This paper examined the relationship between arm morbidity and leisure and recreational activities of affected women. METHODS: Five hundred and forty seven women with stage I-III breast cancer were recruited in four centers across Canada: Surrey (BC); Winnipeg (MB), Montreal (QB) and Fredericton (NB). Participants were enrolled in the study 6-12 months post surgery. Physical examination was used to assess arm and shoulder functioning and questionnaires were used to assess disability, pain, and participation in recreational and leisure activities. RESULTS: At the first clinical assessment (T1), the mean number of months post breast cancer surgery was 8.4. At T1 49% of women reported difficulty with recreational activities that involved "some force or impact" and 29% experienced negative changes to their involvement in leisure activities. A hierarchical multiple regression analysis found that several arm morbidity variables were significant predictors of difficulty with participation in recreational activities. A second hierarchical regression found also that arm morbidity factors were significant predictors of negative changes in leisure activities. Follow-up analyses found that arm morbidity, was most closely related to difficulty with recreational activities requiring free movement of the arm and using force. CONCLUSION: Many women treated for breast cancer experience arm morbidity. Arm morbidity is related to difficulties with recreational activities and negative changes in leisure activity participation. IMPLICATIONS: Breast cancer survivors should engage in recreational and leisure activities that are compatible with reduced range of motion and pain, and avoid those that exacerbate their arm morbidity.
