ABSTRACT

OBJECTIVES: Body image adjustment is a crucial issue for patients with facial cancer, but body image-specific interventions are scarce. We report results of a novel psychotherapeutic intervention to address body image concerns during acute postoperative recovery following facial reconstructive surgery. Our primary aims were to evaluate the intervention's feasibility, acceptability, and efficacy on body image concerns, psychological distress, and quality of life (QOL). METHODS: Adults with facial cancers who endorsed body image concerns were recruited to participate in a randomized controlled trial. The intervention group participated in 4 in-person counseling sessions. The control group received an educational booklet and a brief phone call. Participants completed measures of body image, distress, and QOL at baseline and at the 4-week follow-up to assess the impact of the intervention. Intervention outcomes were assessed with 2 sample t-tests or Mann-Whitney U tests as appropriate. RESULTS: Twenty-nine participants completed both the baseline and follow-up assessments. The intervention demonstrated good feasibility with a high retention rate (79%), visit completion rate (81%), and high satisfaction scores (75% reported mean satisfaction score of >3). Intervention did not result in an observed statistically significant difference in reduction in body image dissatisfaction and disturbance, psychological distress, or improvement in QOL compared with the control group. However, intervention resulted in statistically significant difference in perceived social impact (-1 vs. -8.3, p = 0.033) compared to control group. SIGNIFICANCE OF RESULTS: Our study highlights the potential clinical benefits of a novel psychotherapeutic intervention that targets body image concerns and suggests the need for further evaluation.

ABSTRACT

CONTEXT: Among adolescents and young adults (AYAs), cancer and its treatment can disturb body image in distinct ways compared to younger or older individuals. OBJECTIVE: Since AYA body image is not well understood, this study was designed to develop a conceptual framework for body image in AYAs with cancer. METHODS: Concept elicitation interviews were conducted with 36 AYA patients [10 adolescents (15-17 years), 12 emerging adults (18-25 years), 14 young adults (26-39 years)] and health care providers (n = 36). The constant comparative method was used to analyze for themes and properties, with themes considered saturated if they were present and salient across participant sets. RESULTS: Twenty themes emerged from participant data. Three themes illustrate a shared understanding of patients' experience of body image: (1) physical changes produce shifts in identity and experience of self; (2) precancer body image shapes how the AYA experiences cancer-related physical changes, and (3) changes to the body are upsetting. Nine themes were unique to patients while eight themes were unique to providers. Patient body image experiences were found to evolve over time, largely affected by concerns about how others view them. Providers appeared attuned to AYA patient body image but recognized that it is not systematically addressed with patients. CONCLUSION: More striking than differences between patient groups is the consistency of themes that emerged. The conceptual framework of body image developed from these data offers an important step toward addressing body image concerns for AYA patients.

ABSTRACT

PURPOSE: Weight gain is common among breast cancer patients and may contribute to poorer treatment outcomes. Most programs target breast cancer survivors after the completion of therapy and focus on weight reduction. This study examined the feasibility and preliminary efficacy of an intervention designed to prevent primary weight gain among women receiving neoadjuvant chemotherapy for breast cancer. METHODS: Thirty-eight newly diagnosed stage II or III breast cancer patients were randomized to the BALANCE intervention or usual care within 3 weeks of starting neoadjuvant chemotherapy. The intervention used a size acceptance-based approach and encouraged home-based resistance and moderate-intensity aerobic exercise as well as a low energy-dense diet to prevent weight gain. Assessments were conducted at baseline, mid-chemotherapy (3 months), and post-chemotherapy (6 months). Intervention feasibility, acceptability, and preliminary effects on anthropometric, quality of life, and circulating biomarker measures were evaluated. RESULTS: Intervention participant retention (100%) and in-person session attendance (80%) were high during the intervention period, although attendance dropped to 43% for telephone-delivered sessions. The majority of participants reported being satisfied with the intervention during chemotherapy (88%). Participants in the intervention group had greater reductions in waist circumference (p = .03) and greater improvements in self-reported vitality scores (p = .03) than the control group at the end of chemotherapy. Significant effects on biomarkers were not observed. CONCLUSIONS: A size acceptance weight management program is feasible during neoadjuvant chemotherapy among breast cancer patients and may have beneficial effects on waist circumference and patient vitality. TRIAL REGISTRATION: This study was registered as a clinical trial at www.clinicaltrials.gov (NCT00533338).

ABSTRACT

Characterization of material properties of human skin is required to develop a physics-based biomechanical model that can predict deformation of female breast after cosmetic and reconstructive surgery. In this paper, we have adopted an experimental approach to characterize the biaxial response of human skin using bulge tests. Skin specimens were harvested from breast and abdominal skin of female subjects who underwent mastectomy and/or reconstruction at The University of Texas MD Anderson Cancer Center and who provided informed consent. The specimens were tested within 2 h of harvest, and after freezing for different time periods but not exceeding 6 months. Our experimental results show that storage in a freezer at -20 °C for up to about 40 days does not lead to changes in the mechanical response of the skin beyond statistical variation. Moreover, displacement at the apex of the bulged specimen versus applied pressure varies significantly between different specimens from the same subject and from different subjects. The bulge test results were used in an inverse optimization procedure in order to calibrate two different constitutive material models - the angular integration model proposed by Lanir (1983) and the generalized structure tensor formulation of Gasser et al. (2006). The material parameters were estimated through a cost function that penalized deviations of the displacement and principal curvatures at the apex. Generally, acceptable fits were obtained with both models, although the angular integration model was able to fit the curvatures slightly better than the Gasser et al. model. The range of the model parameters has been extracted for use in physics-based biomechanical models of the breast.

ABSTRACT

Women report difficulty understanding and personalizing breast reconstruction information during the complex and time-limited period of cancer treatment planning. Patient decision aids can help patients become well informed, form realistic expectations, prepare to communicate with the surgical team, and be more satisfied with their decision-making process. METHODS: We engaged patients, providers, and stakeholders in a user-centered design process to develop an online patient decision aid video and interactive workbook for breast reconstruction after mastectomy. The video and workbook introduce breast reconstruction and compare the risks and benefits of 3 key decisions: reconstruction versus no reconstruction, immediate versus delayed, and tissue- versus implant based. Pilot testing using cognitive interviews and pre-/postdecision aid questionnaires assessed acceptability, knowledge, and decision-making values. RESULTS: After viewing the decision aid, patients (n = 20) scored 97.5% correct on a knowledge test; however, the factors driving their decisions were varied. All (n = 40) patients and providers/stakeholders provided over 80% positive acceptability ratings. 97.5% said they would recommend the video and workbook to other women with breast cancer. CONCLUSIONS: The Considering Breast Reconstruction after Mastectomy patient decision aid video and workbook show potential for improving informed decision-making. Delivery before the initial plastic surgery consultation was well supported as a way to give women time to process the information and prepare to talk with the surgical team about their options. The Personal Decision Worksheet shows potential for assessing patients' knowledge and the factors driving their personal decision-making process.

ABSTRACT

OBJECTIVE: Our long-term goal is to develop a normative feedback intervention to support head and neck cancer patients in forming realistic expectations about how other people in non-social group settings will respond to their appearance. This study aimed to evaluate the relationship between observer ratings of facial disfigurement and observer ratings of emotional response when viewing photographs of faces of head and neck cancer patients. METHODS: Seventy-five (75) observers rated their emotional response to each of 144 facial photographs of head and neck cancer patients using the Self-Assessment-Manikin and rated severity of facial disfigurement on a 9-point scale. Body image investment of the observers was measured using the Appearance Schemas Inventory-Revised. A standardized multiple regression model was used to assess the relationship between observer ratings of facial disfigurement and observer ratings of emotional response, taking into consideration the age and sex of the patient depicted in the stimulus photograph, as well as the age, sex, and body image investment of the observer. RESULTS: Observers who had a strong emotional response to a patient's facial photograph tended to rate the patient's facial disfigurement as more severe (standardized regression coefficient ß = 0.328, P < 0.001). Sex and age of the observer had more influence on the rating of facial disfigurement than did the patient's demographic characteristics. Observers more invested in their own body image tended to rate the facial disfigurement as more severe. CONCLUSIONS: This study lays the groundwork for a normative database of emotional response to facial disfigurement.

ABSTRACT

OBJECTIVE: Reconstruction as part of treatment for breast cancer is aimed at mitigating body image concerns after mastectomy. Although algorithms have been developed to objectively assess breast reconstruction outcomes, associations between objectively quantified breast aesthetic appearance and patient-reported body image outcomes have not been examined. Further, the role of appearance investment in explaining a patient's body image is not well understood. We investigated the extent to which objectively quantified breast symmetry and patient-reported appearance investment were associated with body image dissatisfaction in patients undergoing cancer-related breast reconstruction. METHODS: Breast cancer patients in different stages of reconstruction (n = 190) completed self-report measures of appearance investment and body image dissatisfaction. Vertical extent and horizontal extent symmetry values, which are indicators of breast symmetry, were calculated from clinical photographs. Associations among breast symmetry, appearance investment, body image dissatisfaction, and patient clinical factors were examined. Multi-variable regression was used to evaluate the extent to which symmetry and appearance investment were associated with body image dissatisfaction. RESULTS: Vertical extent symmetry, but not horizontal extent symmetry, was associated with body image dissatisfaction. Decreased vertical extent symmetry (ß = -.19, P < .05) and increased appearance investment (ß = .45, P < .001) were significantly associated with greater body image dissatisfaction while controlling for clinical factors. CONCLUSIONS: Breast symmetry and patient appearance investment both significantly contribute to an understanding of patient-reported body image satisfaction during breast reconstruction treatment.

ABSTRACT

Skin is a complex material covering the entire surface of the human body. Studying the mechanical properties of skin to calibrate a constitutive model is of great importance to many applications such as plastic or cosmetic surgery and treatment of skin-based diseases like decubitus ulcers. The main objective of the present study was to identify and calibrate an appropriate material constitutive model for skin and establish certain universal properties that are independent of patient-specific variability. We performed uniaxial tests performed on breast skin specimens freshly harvested during mastectomy. Two different constitutive models - one phenomenological and another microstructurally inspired - were used to interpret the mechanical responses observed in the experiments. Remarkably, we found that the model parameters that characterize dependence on previous maximum stretch (or preconditioning) exhibited specimen-independent universal behavior.

ABSTRACT

PURPOSE: To measure, by quantitative analysis of digital photographs, breast cosmetic outcome within the setting of a randomized trial of conventionally fractionated (CF) and hypofractionated (HF) whole-breast irradiation (WBI), to identify how quantitative cosmesis metrics were associated with patient- and physician-reported cosmesis and whether they differed by treatment arm. METHODS AND MATERIALS: From 2011 to 2014, 287 women aged ≥40 with ductal carcinoma in situ or early invasive breast cancer were randomized to HF-WBI (42.56 Gy/16 fractions [fx] + 10-12.5 Gy/4-5 fx boost) or CF-WBI (50 Gy/25 fx + 10-14 Gy/5-7 fx). At 1 year after treatment we collected digital photographs, patient-reported cosmesis using the Breast Cancer Treatment and Outcomes Scale, and physician-reported cosmesis using the Radiation Therapy Oncology Group scale. Six quantitative measures of breast symmetry, labeled M1-M6, were calculated from anteroposterior digital photographs. For each measure, values closer to 1 imply greater symmetry, and values closer to 0 imply greater asymmetry. Associations between M1-M6 and patient- and physician-reported cosmesis and treatment arm were evaluated using the Kruskal-Wallis test. RESULTS: Among 245 evaluable patients, patient-reported cosmesis was strongly associated with M1 (vertical symmetry measure) (P<.01). Physician-reported cosmesis was similarly correlated with M1 (P<.01) and also with M2 (vertical symmetry, P=.01) and M4 (horizontal symmetry, P=.03). At 1 year after treatment, HF-WBI resulted in better values of M2 (P=.02) and M3 (P<.01) than CF-WBI; treatment arm was not significantly associated with M1, M4, M5, or M6 (P≥.12). CONCLUSIONS: Quantitative assessment of breast photographs reveals similar to improved cosmetic outcome with HF-WBI compared with CF-WBI 1 year after treatment. Assessing cosmetic outcome using these measures could be useful for future comparative effectiveness studies and outcome reporting.

ABSTRACT

The International Psycho-Oncology Society (IPOS) Human Rights Task Force has been working since 2008 to raise awareness and support, for the relevance of psychosocial cancer care as a human rights issue. In 2014 the "Lisbon Declaration: Psychosocial Cancer Care as a Universal Human Right" was fully endorsed by IPOS. Subsequently, the IPOS Standard on Quality Cancer Care, endorsed by 75 cancer organizations worldwide, has been updated and now includes 3 core principles: Psychosocial cancer care should be recognised as a universal human right; Quality cancer care must integrate the psychosocial domain into routine care; Distress should be measured as the 6th vital sign. The President's plenary held at the 2015 World Congress of Psycho-Oncology in Washington DC was devoted to discussing psychosocial care as a human rights issue. Many challenges and opportunities are illustrated in different continents and contexts: from Africa where resources for basic cancer treatment are scarce and children and their parents face significant difficulties with hospital detention practices; to Europe where for many countries psychosocial care is still seen as a luxury; and the Middle East where Muslim women face stigma and a culture of silence over cancer. We further discuss how to move the Lisbon Declaration forward towards its implementation into clinical practice globally, using the successful example of the World Health Assembly resolution supporting palliative care as a human right which has achieved widespread approval, and identifying the vital role the IPOS Federation of National Psychoncology Societies plays worldwide to move this agenda forward.

ABSTRACT

Stereophotography is now finding a niche in clinical breast surgery, and several methods for quantitatively measuring breast morphology from 3D surface images have been developed. Breast ptosis (sagging of the breast), which refers to the extent by which the nipple is lower than the inframammary fold (the contour along which the inferior part of the breast attaches to the chest wall), is an important morphological parameter that is frequently used for assessing the outcome of breast surgery. This study presents a novel algorithm that utilizes three-dimensional (3D) features such as surface curvature and orientation for the assessment of breast ptosis from 3D scans of the female torso. The performance of the computational approach proposed was compared against the consensus of manual ptosis ratings by nine plastic surgeons, and that of current 2D photogrammetric methods. Compared to the 2D methods, the average accuracy for 3D features was ~13% higher, with an increase in precision, recall, and F-score of 37%, 29%, and 33%, respectively. The computational approach proposed provides an improved and unbiased objective method for rating ptosis when compared to qualitative visualization by observers, and distance based 2D photogrammetry approaches.

ABSTRACT

BACKGROUND: The authors compared longitudinal patient-reported outcomes and physician-rated cosmesis with conventionally fractionated whole-breast irradiation (CF-WBI) versus hypofractionated whole-breast irradiation (HF-WBI) within the context of a randomized trial. METHODS: From 2011 to 2014, a total of 287 women with American Joint Committee on Cancer stage 0 to stage II breast cancer were randomized to receive CF-WBI (at a dose of 50 grays in 25 fractions plus a tumor bed boost) or HF-WBI (at a dose of 42.56 grays in 16 fractions plus a tumor bed boost) after breast-conserving surgery. Patient-reported outcomes were assessed using the Breast Cancer Treatment Outcome Scale (BCTOS), the Functional Assessment of Cancer Therapy-Breast, and the Body Image Scale and were recorded at baseline and 0.5, 1, 2, and 3 years after radiotherapy. Physician-rated cosmesis was assessed at the same time points. Outcomes by treatment arm were compared at each time point using a 2-sided Student t test. Multivariable mixed effects growth curve models assessed the effects of treatment arm and time on longitudinal outcomes. RESULTS: Of the 287 patients enrolled, 149 were randomized to CF-WBI and 138 were randomized to HF-WBI. At 2 years, the Functional Assessment of Cancer Therapy-Breast Trial Outcome Index score was found to be modestly better in the HF-WBI arm (mean 79.6 vs 75.9 for CF-WBI; P = .02). In multivariable mixed effects models, treatment arm was not found to be associated with longitudinal outcomes after adjusting for time and baseline outcome measures (P≥.14). The linear effect of time was significant for BCTOS measures of functional status (P = .001, improved with time) and breast pain (P = .002, improved with time). CONCLUSIONS: In this randomized trial, longitudinal outcomes did not appear to differ by treatment arm. Patient-reported functional and pain outcomes improved over time. These findings are relevant when counseling patients regarding decisions concerning radiotherapy. Cancer 2016. © 2016 American Cancer Society.

ABSTRACT

BACKGROUND: Patients with cancer undergoing head and neck reconstruction can experience significant distress from alterations in appearance and bodily functioning. We sought to delineate salient dimensions of body image concerns in this patient population preparing for reconstructive surgery. METHODS: Participants completed self-report questionnaires evaluating numerous aspects of body image. We used Bayesian factor analysis modeling methods to identify latent factors emerging from the data. RESULTS: We identified 2 latent factors: appearance distress and functional difficulties. The highest level of preoperative body image concerns were related to distress about appearance changes and its perceived social consequences. Appearance distress items displayed greater variability compared with functional difficulties. CONCLUSION: Appearance and functional changes to body image are important areas of concern for patients with head and neck cancer as they prepare for reconstructive surgery. Knowledge regarding specific body image issues can be used to guide psychosocial assessments and intervention to enhance patient care. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1035-1042, 2016.

ABSTRACT

OBJECTIVE: The process of cancer-related breast reconstruction is typically multi-staged and can take months to years to complete, yet few studies have examined patient psychosocial well-being during the reconstruction process. We investigated the effects of reconstruction timing and reconstruction stage on body image and quality of life at specific time points during the breast reconstruction process. METHODS: In this cross-sectional study, 216 patients were grouped into four reconstructive stages: pre-reconstruction, completed stage 1, completed stage 2, and final stages. Multiple regression analyses examined the roles of reconstruction timing (immediate vs delayed reconstruction) and reconstruction stage as well as their interaction in predicting body image and quality of life, controlling for patient age, BMI, type of reconstruction, chemotherapy, radiation therapy, and major complication(s). RESULTS: A difference in pattern of body image was observed across the reconstructive stages, with those receiving delayed reconstruction showing significant decrease in body image dissatisfaction compared with those with immediate reconstruction. At pre-reconstruction, patients awaiting delayed reconstruction reported significantly lower social well-being compared with those awaiting immediate reconstruction. Reconstruction stage predicted emotional well-being, with higher emotional well-being observed in those who had commenced reconstruction. CONCLUSIONS: Timing and stage of reconstruction are important to consider when examining psychosocial outcomes of breast cancer patients undergoing reconstruction. Those waiting to initiate delayed reconstruction appear at particular risk for body image, emotional, and social distress. Our findings have implications for delivery of psychosocial treatment to maximize body image and quality of life of patients undergoing cancer-related breast reconstruction.Copyright © 2015 John Wiley & Sons, Ltd.

ABSTRACT

Breast cancer-related lymphedema is associated with numerous adverse outcomes. This study investigated the extent clinical factors, lymphedema symptoms, lymphedema-related appearance, and coping strategies predicted quality of life. Female patients who underwent microsurgical treatment for lymphedema (n = 54) participated. Lymphedema symptoms were associated with physical and functional well-being, but not emotional and social well-being. Clinical factors and lymphedema-related appearance were not significantly associated with quality of life. Compared to adaptive coping strategies, maladaptive coping strategies (e.g. denial, venting, self-blame) were more strongly associated with quality of life. This suggests psychosocial interventions aimed at modifying maladaptive coping behaviors can potentially improve quality of life for this patient population.

ABSTRACT

Stereophotogrammetry is finding increased use in clinical breast surgery, both for breast reconstruction after oncological procedures and cosmetic augmentation and reduction. The ability to visualize and quantify morphological features of the breast facilitates pre-operative planning and post-operative outcome assessment. The contour outlining the lower half of the breast is important for the quantitative assessment of breast aesthetics. Based on this inferior breast contour, relevant morphological measures, such as breast symmetry, volume, and ptosis, can be determined. In this paper, we present an approach for automatically detecting the inferior contour of the breast in 3D images. Our approach employs surface curvature analysis and is able to detect the breast contour with high accuracy, achieving an average error of 1.64 mm and a dice coefficient in the range of 0.72-0.87 when compared with the manually annotated contour (ground truth). In addition, the detected contour is used to facilitate the detection of the lowest visible point on the breast, which is an important landmark for breast morphometric analysis.

ABSTRACT

BACKGROUND: Patients with facial cancers can experience disfigurement as they may undergo considerable appearance changes from their illness and its treatment. Individuals with difficulties adjusting to facial cancer are concerned about how others perceive and evaluate their appearance. Therefore, it is important to understand how humans perceive disfigured faces. We describe a new strategy that allows simulation of surgically plausible facial disfigurement on a novel face for elucidating the human perception on facial disfigurement. METHOD: Longitudinal 3D facial images of patients (N = 17) with facial disfigurement due to cancer treatment were replicated using a facial mannequin model, by applying Thin-Plate Spline (TPS) warping and linear interpolation on the facial mannequin model in polar coordinates. Principal Component Analysis (PCA) was used to capture longitudinal structural and textural variations found within each patient with facial disfigurement arising from the treatment. We treated such variations as disfigurement. Each disfigurement was smoothly stitched on a healthy face by seeking a Poisson solution to guided interpolation using the gradient of the learned disfigurement as the guidance field vector. The modeling technique was quantitatively evaluated. In addition, panel ratings of experienced medical professionals on the plausibility of simulation were used to evaluate the proposed disfigurement model. RESULTS: The algorithm reproduced the given face effectively using a facial mannequin model with less than 4.4 mm maximum error for the validation fiducial points that were not used for the processing. Panel ratings of experienced medical professionals on the plausibility of simulation showed that the disfigurement model (especially for peripheral disfigurement) yielded predictions comparable to the real disfigurements. CONCLUSIONS: The modeling technique of this study is able to capture facial disfigurements and its simulation represents plausible outcomes of reconstructive surgery for facial cancers. Thus, our technique can be used to study human perception on facial disfigurement.

ABSTRACT

Three-dimensional (3D) surface imaging of breasts is usually done with the patient in an upright position, which does not permit comparison of changes in breast morphology with changes in position of the torso. In theory, these limitations may be eliminated if the 3D camera system could remain fixed relative to the woman's torso as she is tilted from 0 to 90°. We mounted a 3dMDtorso imaging system onto a bariatric tilt table to image breasts at different tilt angles. The images were validated using a rigid plastic mannequin and the metrics compared to breast metrics obtained from five subjects with diverse morphology. The differences between distances between the same fiducial marks differed between the supine and upright positions by less than 1% for the mannequin, whereas the differences for distances between the same fiducial marks on the breasts of the five subjects differed significantly and could be correlated with body mass index and brassiere cup size for each position change. We show that a tilt table-3D imaging system can be used to determine quantitative changes in the morphology of ptotic breasts when the subject is tilted to various angles.

ABSTRACT

Breast cancer and its treatment can significantly affect a woman's body image. As such, it would be useful to understand the importance or value these patients place on their appearance. We evaluated the factor structure of the Appearance Schemas Inventory-Revised (ASI-R), a measure of body image investment, with a sample of 356 breast cancer patients undergoing mastectomy and breast reconstruction. Using confirmatory and exploratory factor analyses, we found that a three-factor model demonstrated an improvement in fit over the original two-factor structure of the ASI-R. These factors were named Appearance Self-Evaluation, Appearance Power/Control, and Appearance Standards and Behavior. The three aforementioned factors demonstrated acceptable internal consistency reliabilities. Our findings have implications for the use of the ASI-R in an oncology setting, specifically for breast cancer patients undergoing reconstruction.

ABSTRACT

OBJECTIVE: Depression and reduced quality of life are often reported in patients with upper-extremity lymphedema secondary to breast cancer treatment. Little is known about how pain and body image influence depression in patients with lymphedema. The current study examined the association of pain intensity and body integrity beliefs with depressive symptoms and the extent to which body image dissatisfaction mediated these associations. METHODS: A cross-sectional sample of patients with lymphedema secondary to breast cancer treatment completed self-report questionnaires of pain, body image, and depressive symptoms. Hierarchical regression analyses and tests of mediation were conducted to examine the associations among the variables of interest. RESULTS: Pain intensity and body integrity beliefs were positively associated with depressive symptoms. Further, body image dissatisfaction mediated the relationship between pain and depressive symptoms, indicating that higher levels of pain led to higher states of body image dissatisfaction, which, in turn, led to greater depressive symptoms. Body image dissatisfaction also mediated the relationship between body integrity beliefs and depressive symptoms, suggesting that greater body integrity beliefs led to higher dissatisfaction with one's body and subsequently to greater depressive symptoms. CONCLUSIONS: Our findings provide preliminary evidence that pain intensity and body image are important factors in understanding depressive symptoms in patients with lymphedema. Clinical implications include screening for pain and body image concerns in this population to identify patients who are in distress. Counseling interventions targeting body image dissatisfaction can also be potentially helpful for patients with lymphedema.
