Hand Edema in Patients at Risk of Breast Cancer-Related Lymphedema: Health Professionals Should Take Notice

Role of Posttreatment Nursing Based on Functional Magnetic Resonance Imaging in Breast Cancer Patients with Lymphedema

Breast cancer is the tumor disease with the highest incidence in women, especially lymphedema after treatment, which seriously affects the quality of life of women. In order to improve the nursing quality of breast cancer patients, medical staff uses functional magnetic resonance imaging (fMRI) to intervene in breast cancer patients, which greatly improves the recovery speed of patients. In this paper, functional magnetic resonance imaging based on the image registration method is proposed and applied to the follow-up of patients with breast cancer lymphedema after treatment. The powerful imaging effect allows doctors to timely and accurately judge the condition of the patient’s lesions after treatment, which is conducive to nursing care. The experimental results of this paper show that the total number of serious patients in group A before the experiment is 25, accounting for 83.3%. After the experiment, the total number of severe cases was 24, accounting for 80%, indicating that the nursing measures of group A did not have a great effect. The total number of severe cases in group B before the experiment was 27, accounting for 90%. The total number of severe cases after the experiment was 10, accounting for 33.3%. The effect after the experiment was significantly higher than that before the experiment, indicating that the nursing program of group B played a great role.

Safety and Feasibility of a Kinesiotape Application for Secondary Hand Lymphedema: A Case Series

Background: The safety and feasibility of using kinesiotape as a short-term alternative treatment to compression garments or gloves for hand lymphedema have not been examined. The aim of this study was to examine if kinesiotape could maintain size and extracellular fluid (ECF) volume of the hand and forearm, as well as upper limb function and quality of life for women with secondary hand lymphedema. Methods and Results: Six women with secondary hand lymphedema underwent pretreatment measurements, including hand and digit size using a tape measure; ECF volume using bioimpedance spectroscopy; and patient-reported outcome measurements of upper limb function and quality of life. Kinesiotape was then applied to the dorsum of the hand and left for 48 h, during which participants were asked not to wear compression garments. Posttreatment measurements were completed after kinesiotape removal. Changes in measurements were compared to the smallest detectable change (SDC). Hand size did not change more than the SDC; however, a single affected digit increased in circumference by more than the SDC. Changes of the whole arm ECF volume were less than the SDC. The ECF volume of the dorsum of the hand increased in one and decreased in another participant. The forearm ECF volume decreased in two participants. Upper limb function and quality of life did not change. No adverse event was reported. Conclusion: Short-term kinesiotape use appears to be safe in maintaining the physical presentation of hand lymphedema. However, these results should be examined in a larger sample. The feasibility of using kinesiotape as an alternative treatment to compression requires further investigation.

Lymphedema Signs, Symptoms, and Diagnosis in Women Who Are in Minority and Low-Income Groups and Have Survived Breast Cancer

BACKGROUND

Breast cancer-related lymphedema (BCRL) is a well-known side effect of cancer and its treatment with wide-ranging prevalence estimates.

OBJECTIVE

This study describes associations between breast cancer-related lymphedema (BCRL) signs, symptoms, and diagnosis for women who were African American, white, or had a low income and survived breast cancer.

DESIGN

This is a cross-sectional, observational study that used a computer-assisted telephone interview.

METHODS

Women who had survived breast cancer were queried on the presence of 5 lymphedema signs and symptoms (edema in the breast, axilla, arm, and/or hand; tissue fibrosis; pitting; hemosiderin staining; heaviness) and whether they had a diagnosis of BCRL. Relationships between signs/symptoms and diagnosis for each group were evaluated with kappa and chi-square statistics.

RESULTS

The study sample included 528 women who had survived breast cancer (266 white and 262 African American), with 514 reporting complete data on household income; 45% of the latter reported an annual household income of ≤$20,000. Women who were African American or had a low income were nearly twice as likely as women who were white to have any of 8 signs/symptoms of BCRL. Regardless of race and income, >50% of women with all BCRL signs and symptoms reported that they were not diagnosed with BCRL.

LIMITATIONS

The main limitations of our study are the lack of medical chart data and longitudinal design.

CONCLUSIONS

Women who were African American or had a low income and had survived breast cancer had a greater burden of BCRL signs and symptoms than women who were white. The lack of a strong association between BCRL signs, symptoms, and diagnosis suggests that BCRL may be underdiagnosed. These findings suggest that more rigorous screening and detection of BCRL-especially for women who are African American or have a low income-may be warranted. Cancer rehabilitation programs may be able to fill this gap.

A personalized computational model of edema formation in myocarditis based on long-axis biventricular MRI images

Background

Myocarditis is defined as the inflammation of the myocardium, i.e. the cardiac muscle. Among the reasons that lead to this disease, we may include infections caused by a virus, bacteria, protozoa, fungus, and others. One of the signs of the inflammation is the formation of edema, which may be a consequence of the interaction between interstitial fluid dynamics and immune response. This complex physiological process was mathematically modeled using a nonlinear system of partial differential equations (PDE) based on porous media approach. By combing a model based on Biot’s poroelasticity theory with a model for the immune response we developed a new hydro-mechanical model for inflammatory edema. To verify this new computational model, T2 parametric mapping obtained by Magnetic Resonance (MR) imaging was used to identify the region of edema in a patient diagnosed with unspecific myocarditis.

Results

A patient-specific geometrical model was created using MRI images from the patient with myocarditis. With this model, edema formation was simulated using the proposed hydro-mechanical mathematical model in a two-dimensional domain. The computer simulations allowed us to correlate spatiotemporal dynamics of representative cells of the immune systems, such as leucocytes and the pathogen, with fluid accumulation and cardiac tissue deformation.

Conclusions

This study demonstrates that the proposed mathematical model is a very promising tool to better understand edema formation in myocarditis. Simulations obtained from a patient-specific model reproduced important aspects related to the formation of cardiac edema, its area, position, and shape, and how these features are related to immune response.

Perometry versus simulated circumferential tape measurement for the detection of breast cancer-related lymphedema

PURPOSE

Despite increasing emphasis on screening and early intervention for breast cancer-related lymphedema (BCRL), there is marked heterogeneity in diagnostic methodology, including for volumetric measures. This retrospective study compared two volumetric modalities, perometry and simulated circumferential tape measurement (anatomic- and interval-based), for BCRL detection.

METHODS

Between 2005 and 2017, 287 female patients with unilateral breast cancer were prospectively screened for BCRL by perometry and the relative volume change (RVC) formula. Circumferential measurement was performed by sampling at five anatomic landmark-based points or 4-cm intervals from pairs of perometer arm diameter measurements. Volumetric conversion was by a frustum model. The Bland-Altman method was used to compare segmental volume differences. Confusion matrix analysis was performed for each circumferential measurement technique against perometry.

RESULTS

Median follow-up was 34.7 months over 4 postoperative visits. There was no difference in total arm volume comparing any of the circumferential measurement techniques to perometry. Landmark-based methods significantly underestimated upper arm volume (mean difference - 207 mL [- 336, - 78 mL]) and overestimated forearm volume (mean difference + 170 mL [+ 105, + 237 mL]). Landmark-based methods had greater sensitivity and specificity compared to 4-cm interval methods for detection of both RVC ≥ 10 and 5-10%. Landmark-based methods were comparable to perometry for detection of RVC ≥ 10%, but sensitivity was only 63.2-66.7% for RVC 5-10%.

CONCLUSIONS

This hypothesis-generating study suggested the superiority of anatomic landmark-based circumferential tape measurement compared to interval-based methods, while generating questions about the underestimation of upper arm volume and overestimation of forearm volume of circumferential tape measurement compared to perometry.
