Background Single-frequency bioelectrical impedance has been used in clinical and research settings to measure extracellular fluid in arms. Its ease of use and low risk of user error suggests this measurement method may have advantages for use in nonlaboratory (community-based) environments when compared to other measurement methods. The purpose of this study was to evaluate the feasibility of using single-frequency bioelectrical impedance to detect upper limb lymphedema in nonlaboratory settings. Methods and Results Using a standardized protocol, impedance ratios among healthy normal women, breast cancer survivors with lymphedema, and breast cancer survivors without lymphedema were compared with participants seated in an upright position conducive for use outside laboratory settings (community-based environments). Ratios of healthy normal controls and breast cancer survivor groups without lymphedema were very similar, with almost complete overlap in confidence intervals. However, those values were markedly different from the values assessed in the survivor group with lymphedema (p < 0.001). Conclusions These findings suggest impedance ratios determined by single-frequency bioelectrical impedance can be used as markers for lymphedema in nonlaboratory settings when a standardized protocol is used.

Background Breast cancer survivors with lymphedema face a lifetime of stressful physical and emotional symptoms and challenging self-care demands. An in-depth understanding of the perceptions and feelings surrounding life with lymphedema is critical to developing effective supportive care approaches. Objective To explore perceptions and feelings related to lymphedema in breast cancer survivors. Method The expressive writings of 39 individuals were evaluated for this descriptive qualitative study. Data were analyzed using conventional content analysis. Results Qualitative analyses produced four major themes: (1) marginalization and minimization; (2) multiplying losses; (3) yearning to return to normal; (4) uplifting resources. Sub-themes for each major theme were also identified. Conclusion The lymphedema experiences of breast cancer survivors reveal perceptions of marginalization from healthcare providers who are not well informed about lymphedema management and minimize its impact. Multiple distressing losses confront these patients on a daily basis, including body image disturbances, loss of functionality and control over time, permanent uncertainty, and adverse effects on relationships. The daily challenges of lymphedema often result in cumulative frustration and resentment that contribute to failure to perform self-care. Normalcy has been lost, never to return. These women find solace, encouragement and hope to meet the challenges of lymphedema through support from others and their spiritual beliefs. Implication for Practice Healthcare providers need greater awareness of the physical and psychosocial effects of lymphedema in breast cancer survivors. Nurses have unique opportunities to serve as advocates for reducing perceived marginalization and promoting effective self-care and other activities that promote psychological well-being and reduce physical deterioration.

Breast cancer survivors with lymphedema experience physical, psychosocial, and quality-of-life difficulties. Cancer treatment-related lymphedema often is viewed as a disabling condition, and that assumption has fostered an environment in which oncology nurses are not actively involved in the care of patients with lymphedema. Little is known about how breast cancer survivors with lymphedema structure their daily lives. This article describes an effort to determine whether lymphedema truly is a disabling condition by collecting symptom data and self-generated narratives from breast cancer survivors with lymphedema regarding their eating habits, daily activities, substance use, and future plans. Although the sample experienced multiple symptoms, lymphedema duration and degree of extracellular arm fluid did not appear to influence those symptoms. In addition, participants led full, rich, busy lives. The findings do not support the notion that patients with lymphedema live as disabled people. A disability model may not be optimal to guide research design or patient care; rather, a symptom management model better explains the findings and implies that active involvement by nurses in lymphedema patient care and education is indicated.

Background: A significant percentage of breast cancer survivors are at risk for lymphedema for which lifelong self-care is required. Previous studies suggest that less than 50% of breast cancer survivors with lymphedema (BCS-LE) perform prescribed self-care tasks and that even wearing a compression sleeve, the most commonly reported self-care activity, is done irregularly. Reasons for poor self-care adherence include perceived lack of results from self-care (no available arm volume data) and perceived inability to manage the condition. Methods and Results: A two-part pilot study was conducted to: 1) develop and determine the feasibility of a selfmeasurement protocol using a single frequency bioelectrical impedance device; and 2) examine daily variation in extracellular volume in healthy and lymphedematous limbs. Healthy and BCS-LE volunteers were recruited to refine and test a self-measurement protocol. Volunteers were trained in the use of the device and measured for 5 consecutive days in a laboratory setting. They were then given the device to use at home for an additional 5 consecutive days of self-measurement. All volunteers completed each scheduled home measurement. Daily variability in both groups was noted. Conclusions: Home self-measurement using bioelectrical impedance is feasible, acceptable, and captures change. This has implications for both self-care support and for the possibility of incorporating self-measurement using bioelectrical impedance in future clinical trials examining effectiveness of lymphedema treatment.
