Lymphedema after treatment of breast cancer

Axilla Management in Breast Cancer Surgery: Brief Review and Current Practice Recommendations

The diagnostic and therapeutic approach to the axilla in breast cancer patients has changed significantly over the past 30 years, with the replacement of complete axillary lymph node dissection practices by less invasive approaches. Reference is made to clinical findings that have led to practical treatment recommendations and are paving the way to new levels of de-escalation in breast cancer surgery.

Can resistance exercise prevent breast cancer-related lymphoedema? A systematic review and metanalysis protocol

INTRODUCTION

Evidence shows that resistance training (RT) reduces lymphoedema in patients with breast cancer-related lymphoedema (BRCL), making it a safe and efficient intervention. However, it is uncertain if RT is safe and effective in patients at risk of developing BRCL. This systematic review (SR) protocol aims to describe all methodological aspects in order to evaluate the short-, medium- and long-term effects of RT on the prevention of BCRL.

MATERIALS AND METHODS

Throughout 2024, randomised clinical trials (RCTs) will be identified in electronic databases MEDLINE/PubMed, Embase, Cochrane Central Register of Controlled Trials, PEDro and LILACS. Only studies in English, Spanish and Portuguese will be included. Grey literature and clinical trial registration will also be reviewed. The primary outcome will be the occurrence of lymphoedema and quality of life. Second, pain intensity, upper limb function, range of movement, grip strength and adverse events will be considered. The individual studies' risk of bias will be evaluated using the Cochrane Risk of Bias 2.0 tool. Pairwise meta-analyses using a frequentist approach and random effects model will be conducted. The Grading of Recommendations Assessment, Development and Evaluation system will be used to evaluate the certainty of the evidence.

ETHICS AND DISSEMINATION

This protocol does not require the approval of an ethics committee, as it is a secondary study. The results will be disseminated through peer-reviewed publications.

Analysis and relationship between the volume of upper limb lymphoedema and pressure pain threshold, neural range of motion, pain intensity, kinesiophobia, pain hypervigilance and catastrophizing in breast cancer survivors

BACKGROUND

Lymphedema of the upper limbs and persistent pain are frequent sequelae after surgical treatment of breast cancer.

AIM

The aim of this paper was to analyze the upper limb volume, pressure pain threshold, neural range of motion, pain intensity, kinesiophobia, pain hypervigilance and catastrophizing in patients with and without lymphoedema after breast cancer surgery. Secondly, we aimed to investigated the association between upper limb volume and these variables.

DESIGN

Descriptive observational study.

SETTING

Faculty of Health Sciences of the University of Granada.

POPULATION

Fifty-eight post-surgical breast cancer survivors, 29 with upper limb lymphoedema and 29 without lymphoedema.

METHODS

We measured upper limb volume (perimetric method). Also, pressure pain thresholds were assessed with a digital algometer, neural range of motion (neurodynamic test for radial, ulnar and median nerves), pain intensity (visual analogue scale), kinesiophobia, pain hypervigilance and catastrophizing (validated tests). To detect differences between the groups for the measurement variables we performed a t-test for independent samples analysis. A simple linear regression analysis adjusting for age and body mass index was performed to check the association among upper limb volume and pain variables in the group with lymphoedema.

RESULTS

The analysis showed that lymphoedema group had lower pressure pain threshold bilaterally in the masseter (origin P≤0.036; insertion P≤0.046), temporalis (insertion P≤0.021), suboccipitalis (P≤0.036); second (P≤0.014), third (P≤0.001) and tenth rib (P≤0.001); affected side of the temporalis (origin P=0.025); temporomandibular joint (P=0.024); neural range of motion in the median nerve (P=0.047), ulnar (P=0.042) on the affected side and radial (P=0.039) on the unaffected side; and greater kinesiophobia (P=0.042). Linear regression analysis only showed a significant association between upper limb volume and neural range of motion in the radial nerve (P=0.020) in the lymphedema group. No significant associations were obtained for the rest of variables.

CONCLUSIONS

These findings suggest that the presence of lymphoedema may contribute to an increased level of generalized mechanosensitivity and fear to movement in this population.

CLINICAL REHABILITATION IMPACT

Upper limb lymphedema can lead to heightened mechanosensitivity and movement-related fear in breast cancer survivors. Therefore, fast track rehabilitation approach should be focus in screening and rehabilitation methods for detection and control this sequalae.

Knowledge, Attitude, and Practice of Breast Cancer Patients Toward Lymphedema Complications: Cross-Sectional Study

Breast cancer is commonly treated through surgical resection, but a common complication of the procedure is lymphedema of the upper limbs, which can significantly impact patients' daily life. This study aims to investigate the knowledge, attitude, and practice (KAP) of breast cancer patients with regard to lymphedema complications. This cross-sectional study was conducted by a self-administered questionnaire between August and October 2022 toward breast cancer patients in our Hospital of Traditional Chinese Medicine. A total of 529 breast cancer patients were enrolled, including 186 (35.16%) aged < 50 years old. Participants had moderate knowledge, attitudes, and practices with scores of 18.24 ± 3.145 (possible range: 0-30), 62.24 ± 10.260 (possible range: 17-85), and 63.27 ± 20.967 (possible range: 21-105), respectively. Multivariate logistic regression showed that high school/technical secondary school (OR = 1.880, 95% CI = 1.107-3.194, P = 0.019) and being retired (OR = 0.482, 95% CI = 0.245-0.947, P = 0.034) were independently associated with good knowledge. Knowledge (OR = 1.321, 95% CI = 1.222-1.428, P < 0.001) was independently associated with a good attitude. Furthermore, knowledge (OR = 1.262, 95% CI = 1.151-1.384, P < 0.001) and attitude (OR = 1.122, 95% CI = 1.085-1.160, P < 0.001) were independently associated with good practice. Breast cancer patients have moderate knowledge, attitudes, and practices regarding lymphedema complications. Effective education and self-management programs are needed to improve patients' KAP toward lymphedema.

A National Health and Wellness SMS Text Message Program for Breast Cancer Survivors During COVID-19 (EMPOWER-SMS COVID-19): Mixed Methods Evaluation Using the RE-AIM Framework

BACKGROUND

COVID-19 lockdowns caused widespread closures of supportive care services for breast cancer survivors in Australia. In a randomized controlled trial, our team's lifestyle-focused, evidence-based SMS text message support program (EMPOWER-SMS COVID-19) was found to be acceptable and useful for breast cancer survivors, and it was ready for rapid widespread delivery.

OBJECTIVE

This study aims to evaluate the reach (uptake) of an adapted 3-month lifestyle-focused SMS text message program (EMPOWER-SMS COVID-19) and barriers and enablers to implementation using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework.

METHODS

A mixed methods pre-post study was conducted to evaluate the EMPOWER-SMS COVID-19 program. The study evaluated the following aspects: (1) reach/representativeness, which refers to the proportion of participant enrollment (ie, number enrolled/number that visited the study website) and demographics (eg, age, sex, ethnicity, time since completing treatment, Index of Relative Socio-economic Advantage and Disadvantage [IRSAD; quintile 1, which refers to most disadvantaged areas, to quintile 5, which refers to least disadvantaged areas, and remoteness); (2) effectiveness, in which participant engagement and acceptability were evaluated using SMS text message reply data and a feedback survey (5-point Likert scale and free-text responses); (3) adoption, which corresponds to the proportion of organizations or health professionals who agreed to promote the program; (4) implementation fidelity and maintenance, which evaluated SMS text message delivery data, opt-outs, costs, and adaptations. Quantitative data were summarized using means and SDs or frequencies and percentages, while qualitative data were analyzed thematically.

RESULTS

With regard to the reach/representativeness of the program, 841/1340 (62.8%) participants enrolled and provided electronic consent. Participants had a mean age of 58.8 (SD 9.8; range 30-87) years. According to the data collected, most participants identified as female (837/840, 99.6%) and White (736/840, 87.6%) and nearly half (418/841, 49.7%) finished treatment ≤18 months ago. Most resided in major cities (574/838, 68.5%) and 30% (251/838) in IRSAD quintile 1 or 2. In terms of effectiveness, 852 replies were received from 511 unique participants (median 1; range 1-26). The most common replies were participants stating how they heard about the program (467/852, 54.8%) or "thank you" (131/852, 15.4%). None of the replies contained urgent safety concerns. Among participants who provided feedback (449/841, 53.4%), most "(strongly) agreed" the SMS text messages were easy to understand (445/448, 99.3%), useful (373/440, 84.8%), helped participants feel supported (388/448, 86.6%), and motivated participants to be physically active (312/445, 70.1%) and eat healthier (313/457, 68.5%). Free-text responses revealed 5 factors influencing engagement: (1) feeling supported and less alone, (2) motivation and reassurance for health self-management, (3) the variety of information, (4) weblinks to information and resources, and (5) the option to save the SMS text messages. Concerning adoption, 50% (18/36) of organizations/health professionals agreed to promote the program. With regard to implementation/maintenance, SMS text messages were delivered as planned (97.43% [41,257/42,344] of SMS text messages were successfully delivered) with minimal opt-outs (62/838, 7.4%) and low cost (Aus $15.40/participant; Aus $1=US $0.67). No adaptations were made during the intervention period. Postintervention adaptations included adding weblinks and participant-selected customizations.

CONCLUSIONS

EMPOWER-SMS COVID-19 was implemented quickly, had a broad reach, and had high engagement and acceptability among socioeconomically diverse participants. The program had high fidelity, low cost, and required minimal staff oversight, which may facilitate future implementation. However, further research is needed to evaluate barriers and enablers to adoption and implementation for health professionals and strategies for long-term maintenance.

Early Disturbance of Lymphatic Transport as a Risk Factor for the Development of Breast-Cancer-Related Lymphedema

Introduction: Breast-cancer-related lymphedema (BCRL) is a frequently occurring and debilitating condition. When lymphedema is diagnosed late, treatment can be expected to be less effective. Lymphofluoroscopy can provide details about the superficial lymphatic architecture and can detect an early disturbance of lymphatic transport (i.e., dermal backflow) before the lymphedema is clinically visible. The main objective of this study is to investigate whether this early disturbance of lymphatic transport visualized by lymphofluoroscopy is a risk factor for the development of BCRL. Methodology: All patients scheduled for unilateral breast cancer surgery with axillary lymph node dissection or sentinel node biopsy were considered. Patients were assessed at baseline and 1, 3, 6, 9, 12, 18, 24 and 36 months postoperatively. During each visit, a clinical assessment was performed to determine the volume difference between both arms and hands (through circumference measurements and water displacement). Clinical BCRL was defined as a ≥5% increase in relative arm volume difference compared to the baseline value. Variables related to (1) the disturbance of lymphatic transport (through lymphofluoroscopy), (2) the demographics and general health of the patient and (3) the breast cancer and treatment of the patient were collected. Results: We included data of 118 patients in the present study. Thirty-eight patients (39.8%) developed BCRL. Early disturbance of lymphatic transport was identified as a risk factor for the development of clinical BCRL (HR 2.808). Breast-cancer- and treatment-related variables such as axillary lymph node dissection (ALND) (HR 15.127), tumor stage (HR 1.745), mastectomy (HR 0.186), number of positive lymph nodes (HR 1.121), number of removed lymph nodes (HR 1.055), radiotherapy of the axilla (HR 2.715), adjuvant taxanes (HR 3.220) and postsurgical complications (HR 2.590) were identified as significant risk factors for the development of BCRL. In the multivariate analysis, age and ALND were withheld as independent risk factors for the development of BCRL. Conclusion: Lymphofluoroscopy can identify an early disturbance of lymphatic transport after breast cancer treatment. Patients with an early disturbance of lymphatic transport are considered to be a high-risk group for the development of BCRL. This study also confirms that age and ALND are predictors for the development of BCRL. Therefore, a surveillance program of these patients with lymphofluoroscopy could be useful to identify lymphedema in subclinical stages.

What Should We Focus on When Managing Breast Cancer-Related Lymphedema to Improve Quality of Life?

Background: Breast cancer-related lymphedema (BCRL) is correlated with poor quality of life (QOL). The effects of the management of lymphedema on QOL remain controversial. We analyzed the changes in QOL and identified factors associated with its improvement to improve the care of patients with BCRL. Methods and Results: A total of 194 patients with BCRL were recruited, and their medical records were reviewed regarding type of surgery, chemotherapy, and radiation. Patients completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaires, and the volume and circumference of lymphedema were measured. Significant improvements in physical, emotional, cognitive, social, and role functioning, and future perspective were observed after BCRL management. However, the change in the size of lymphedema was not correlated with the change in QOL parameters. Conclusion: The management of BCRL has a beneficial effect on QOL. However, changes in the size of lymphedema did not reflect changes in QOL. Therefore, a comprehensive approach for the management of BCRL beyond reducing the size of lymphedema is recommended to improve QOL.

Age as a risk factor for breast cancer-related lymphedema: a systematic review

PURPOSE

Breast cancer-related lymphedema (BCRL) has been widely reported in the medical literature. Various patient characteristics, including age, have been investigated as possible risk factors for this disease entity, but the existence and direction of the cause-and-effect relationship are still unclear. In this review, we aimed to evaluate the effect of age on development of BRCL.

METHODS

PubMed, Scopus, and Ovid MEDLINE were searched for relevant articles, which were found to be published between 1974 and 2020.

RESULTS

Twenty-six studies involving 19,396 patients were selected. The average age of patients was 54.9. 26 studies were included in the final analysis, and 13 articles reported no association between age and BCRL development.

CONCLUSIONS

Though studies presented different findings, the majority did not identify age as a risk factor for development of lymphedema. However, the level of evidence of individual studies was low. In this article, we call attention to the need for uniform design of lymphedema studies and diagnosis.

IMPLICATIONS FOR CANCER SURVIVORS

All patients should be informed and screened regularly for lymphedema during and after the treatment independent of their age.

Use of the Cephalic Vein in DIEP Breast Reconstruction Does Not Increase Risk of Lymphedema of the Ipsilateral Arm

SUMMARY

Flap failure is a rare but devastating complication in deep inferior epigastric perforator (DIEP) flap reconstructions. Common causes of partial or complete flap failure are related to venous congestion. Although the cephalic vein is usually a safe and reliable recipient vein for additional venous outflow, there is a hypothesized risk of donor-arm lymphedema secondary to lymphatic vessel damage in the vicinity of the cephalic vein or related to scarring and reduced venous backflow of the arm. The aim was to assess whether the cephalic vein as an additional recipient vessel, by means of the superficial inferior epigastric vein in DIEP flap breast reconstruction, was associated with long-term volume changes of the arm and/or symptoms of lymphedema. Arm volume was assessed preoperatively in patients scheduled to undergo unilateral delayed DIEP flap breast reconstruction at Uppsala University Hospital, Sweden, between 2001 and 2007. Long-term postoperative assessments were performed in 2015 to 2016. Water displacement and circumferential measurement were assessed preoperatively and postoperatively by the same lymphedema therapists. Patients were divided into two groups: DIEP reconstruction with the cephalic vein or without. Fifty-four patients fulfilled the inclusion criteria and completed the study, with a mean follow-up time of 136 months. There was no increased occurrence of lymphedema in the group undergoing DIEP flap reconstruction with the cephalic vein as extra venous drainage, based on an analysis of change from baseline in arm volume difference.This study shows that the cephalic vein can be used for secondary venous outflow in DIEP breast reconstruction without long-term risk of ipsilateral arm volume increase or symptoms of lymphedema.

Risk factors of unilateral breast cancer-related lymphedema: an updated systematic review and meta-analysis of 84 cohort studies

PURPOSE

To review and update the incidence and risk factors for breast cancer-related lymphedema based on cohort studies.

METHODS

The study was guided by the Joanna Briggs Institute methodology and the Cochrane handbook for systematic reviews. PubMed, EMBASE, CINAHL, Scopus, Web of Science, The Cochrane Library, CNKI, SinoMed, and Wan Fang Database were searched from inception to November 15, 2021. Cohort studies reported adjusted risk factors were selected. PRISMA guideline was followed. Study quality were evaluated using the Newcastle-Ottawa scale. Random-effects models were adopted. The robustness of pooled estimates was validated by meta-regression and subgroup analysis. Lymphedema incidence and adjusted risk factors in the multivariable analyses with hazard / odds ratios and 95% CIs were recorded.

RESULTS

Eighty-four cohort studies involving 58,358 breast cancer patients were included. The pooled incidence of lymphedema was 21.9% (95% CI, 19.8-24.0%). Fourteen factors were identified including ethnicity (black vs. white), higher body mass index, higher weight increase, hypertension, higher cancer stage (III vs. I-II), larger tumor size, mastectomy (vs. breast conservation surgery), axillary lymph nodes dissection, more lymph nodes dissected, higher level of lymph nodes dissection, chemotherapy, radiotherapy, surgery complications, and higher relative volume increase postoperatively. Additionally, breast reconstruction surgery, and adequate finance were found to play a protective role. However, other variables such as age, number of positive lymph nodes, and exercise were not correlated with risk of lymphedema.

CONCLUSION

Treatment-related factors still leading the development of breast cancer-related lymphedema. Other factors such as postoperative weight increase and finance status also play a part. Our findings suggest the need to shift the focus from treatment-related factors to modifiable psycho-social-behavioral factors.

Risk factors for breast cancer-related lymphedema in patients undergoing 3 years of prospective surveillance with intervention

Background

To evaluate risk factors (treatment‐related, comorbidities, and lifestyle) for breast cancer–related lymphedema (BCRL) within the context of a Prospective Surveillance and Early Intervention (PSEI) model of care for subclinical BCRL.

Methods

The parent randomized clinical trial assigned patients newly diagnosed with breast cancer to PSEI with either bioimpedance spectroscopy (BIS) or tape measurement (TM). Surgical, systemic and radiation treatments, comorbidities, and lifestyle factors were recorded. Detection of subclinical BCRL (change from baseline of either BIS L‐Dex ≥6.5 or tape volume ≥ 5% and < 10%) triggered an intervention with compression therapy. Volume change from baseline ≥10% indicated progression to chronic lymphedema and need for complex decongestive physiotherapy. In this secondary analysis, multinomial logistic regressions including main and interaction effects of the study group and risk factors were used to test for factor associations with outcomes (no lymphedema, subclinical lymphedema, progression to chronic lymphedema after intervention, progression to chronic lymphedema without intervention). Post hoc tests of significant interaction effects were conducted using Bonferroni‐corrected alphas of .008; otherwise, an alpha of .05 was used for statistical significance.

Results

The sample (n = 918; TM = 457; BIS = 461) was female with a median age of 58.4 years. Factors associated with BCRL risk included axillary lymph node dissection (ALND) (p < .001), taxane‐based chemotherapy (p < .001), regional nodal irradiation (RNI) (p ≤ .001), body mass index >30 (p = .002), and rurality (p = .037). Mastectomy, age, hypertension, diabetes, seroma, smoking, and air travel were not associated with BCRL risk.

Conclusions

Within the context of 3 years of PSEI for subclinical lymphedema, variables of ALND, taxane‐based chemotherapy, RNI, body mass index >30, and rurality increased risk.

The Prospective Surveillance and Early Intervention Model promotes identification and treatment of subclinical lymphedema, facilitating prevention of chronic lymphedema and risk reduction. Axillary lymph node dissection, taxane‐based chemotherapy, regional nodal irradiation, body mass index >30, and rurality are critical risk factors within the context of the Prospective Surveillance and Early Intervention Model for some patients.

Vascularized Lymph Node Transfer Improved Outcomes of Elderly Patients with Secondary Upper Extremity Lymphedema

BACKGROUND

Secondary lymphedema is a debilitating morbidity. This study investigated the outcomes of vascularized lymph node transfer (VLNT) in elderly patients with secondary upper extremity lymphedema.

METHODS

Between 2008 and 2018, elderly (≥65 years) patients with secondary upper extremity lymphedema who underwent VLNT were retrospectively reviewed. Cheng's Lymphedema Grading, Taiwan Lymphoscintigraphy Staging, and indocyanine green lymphography were used to select the procedures. Outcome measurements included complications, circumferential difference, episodes of cellulitis, and the Lymphedema-Specific Quality of Life questionnaire (LYMQoL).

RESULTS

Eleven patients with a mean age of 70.2 ± 5.3 years (range 65-80 years) who underwent VLNT survived and no major complications were encountered. At a mean follow-up of 6.5 ± 3.6 years (range 2-13 years), the mean limb circumferential difference was significantly improved from 25.6 ± 11.5% to 8.3 ± 4.2% (p = 0.016), and the mean episode of cellulitis was statistically reduced from 2.4 ± 1.3 to 0.4 ± 0.9 times/year (p = 0.007). At a follow-up of 24 months, four domains of Function (from 30.6 ± 2.8 to 14.5 ± 2.5), Appearance (from 18.2 ± 1.9 to 8.5 ± 2.1), Symptoms (from 30.4 ± 5.9 to 10.9 ± 1.0) and Mood (from 29.2 ± 4.4 to 10.7 ± 1.0), as well as overall LYMQoL score (from 3.9 ± 1.1 to 7.4 ± 0.5), showed statistical improvement (all p < 0.05).

CONCLUSIONS

VLNT for secondary upper extremity lymphedema in elderly patients significantly decreased the limb circumferential difference and frequency of cellulitis and improved quality of life without using compression garments postoperatively.

Psychometric Properties of Quality of Life Questionnaires for Patients with Breast Cancer-Related Lymphedema: A Systematic Review

Backgrounds: Assessing quality of life (QoL) using a well-developed and validated questionnaire is an essential part of a breast cancer-related lymphedema (BCRL) treatment. However, a QoL questionnaire with the best psychometric properties is so far unknown. The aim of this systematic review is to evaluate the psychometric properties of the questionnaires measuring the QoL of patients with BCRL. Methods: A thorough search was performed to identify published studies in electronic databases such as Medline (via Ovid), EBSCOhost, PubMed, Scopus, and Web of Science, on 8 February 2022, by using search terms as follows: ‘quality of life’; ‘breast cancer’; ‘upper limb’; ‘lymphedema’; ‘questionnaire’; and ‘measurement properties.’ Two reviewers conducted article selection, data extraction, and quality assessment independently. The third reviewer helped solve any possible disagreements between the two reviewers. The COSMIN checklist and manual were used to assess the quality of included studies. Results: A total of nineteen articles with nine questionnaires were included and assessed using the COSMIN Risk of Bias checklist. Most studies only assessed content validity, structural validity, internal consistency, reliability, and construct validity. Lymph-ICF-UL showed the most ‘sufficient’ and ‘high’ quality of evidence ratings for its measurement properties. Conclusion: The most appropriate questionnaire for use based on our assessment is Lymph-ICF-UL.

Vascularized omental lymphatic transplant for upper extremity lymphedema: A systematic review

BACKGROUND

Vascularized omental lymphatic transplant (VOLT) is an increasingly popular treatment of extremity lymphedema given its promising donor site. While the success of VOLT in the treatment of lymphedema has been reported previously, several questions remain.

AIM

To further elucidate appropriate use of VOLT in the treatment of lymphedema, specifically addressing patient selection, harvest technique, and operative methods.

METHODS AND RESULTS

A systematic review of VOLT for upper extremity lymphedema was performed. Of 115 yield studies, seven were included for analysis based on inclusion and exclusion criteria. Included studies demonstrated significant reductions in extremity circumference/volume (average volume reduction, 22.7%-39.5%) as well as subjective improvements using patient-reported outcomes. Though studies are heterogenous and limited, when analyzed in aggregate, suggest the efficacy of VOLT in lymphedema treatment.

CONCLUSION

This is the largest systematic review of VOLT to date. VOLT continues to show promise as a safe and efficacious surgical intervention for lymphedema in the upper extremity. Further studies are warranted to more definitively identify patients for whom this technique is appropriate as well as ideal harvest and inset technique.

Long-Term Patient Satisfaction and Quality of Life After Breast-Conserving Therapy: A Prospective Study Using the BREAST-Q

Background

Poor patient-reported satisfaction after breast-conserving therapy (BCT) has been associated with impaired health-related quality of life (HRQOL) and subsequent depression in retrospective analysis. This prospective cohort study aimed to assess the HRQOL of patients who have undergone BCT using the BREAST-Q, and to identify clinical risk factors for lower patient satisfaction.

Methods

Patients with primary breast cancer undergoing BCT were asked to complete the BREAST-Q preoperatively (T1) for baseline evaluation, then 3 to 4 weeks postoperatively (T2), and finally 1 year after surgery (T3). Clinicopathologic data were extracted from the patients’ charts. Repeated measures analysis of variance (ANOVA) was used to determine significant differences in mean satisfaction and well-being levels among the test intervals. Multiple linear regression was used to evaluate risk factors for lower satisfaction.

Results

The study enrolled 250 patients. The lowest baseline BREAST-Q score was reported for “satisfaction with breast” (mean, 61 ± 19), but this increased postoperatively (mean, 66 ± 18) and was maintained at the 1 year follow-up evaluation (mean, 67 ± 21). “Physical well-being” decreased from T1 (mean, 82 ± 17) to T2 (mean, 28 ± 13) and did not recover much by T3 (mean, 33 ± 13), being the lowest BREAST-Q score postoperatively and in the 1-year follow-up evaluation. In multiple regression, baseline psychosocial well-being, body mass index (BMI), and type of incision were risk factors for lower “satisfaction with breasts.”

Conclusion

Both the aesthetic/surgery-related and psychological aspects are equally important with regard to “satisfaction with breasts” after BCT. The data could serve as the benchmark for future studies.

Psychometric properties of quality of life questionnaires for patients with breast cancer-related lymphedema: A protocol for a systematic review

BACKGROUND

Breast-cancer related lymphedema (BCRL) is a common condition among breast cancer survivors that could impact the quality of life (QoL) of patients. Exploring the QoL of the patients with BCRL using valid and reliable QoL is crucial to capture the status of this important aspect hence appropriate intervention could be implement to patient. However, so far no scientific review is available, which reports the psychometric properties of the QoL questionnaires used in BCRL. The purpose of this systematic review is to comprehensively assess the psychometric properties of QoL questionnaires in patients with BCRL.

METHODS

We will perform comprehensive searches of published studies in electronic databases such as Medline (via Ovid), EBSCOhost, PubMed, Scopus, and Web of Science by using the following search terms: "quality of life"; "breast cancer"; "upper limb"; "lymphedema"; "questionnaire"; and "measurement properties." Only full-text articles in English language are included. Two reviewers will independently conduct the article selection, data extraction, and quality assessment. Any possible conflict between the 2 reviewers is going to be solved with the help of a third reviewer. The Consensus-based Standards for the Selection of Health Measurement Instrument (COSMIN) checklist and manual will be used to assess the selected study quality.

RESULTS

This review will provide an updated overview of available lymphedema-specific questionnaires used in BCRL population and then recommend the most valid and reliable QoL questionnaire for clinical and research use in patients with BCRL.

CONCLUSION

This review may help the clinician and researcher to find an updated overview of various questionnaires used to assess BCRL patients' QoL.

ETHICS AND DISSEMINATION

This review will use data from published studies. Therefore, ethical approval is not required prior to this review. The results of this review will be published in a peer-reviewed journal or presented at conferences.

Lymphedema Information and Prevention Practices of Women After Breast Cancer Surgery

AIM

This study was carried out to determine women's knowledge about lymphedema precautions and their practice status. The sample of this descriptive and correlationally designed study included 107 women who underwent surgery.

METHOD

This descriptive study's data were collected using a questionnaire form developed by the researcher. The data were structured on a 3-point Likert-type scale. The one-way analysis of variance, correlations, and the Kolmogorov-Smirnov test were used in the statistical analysis.

RESULTS

Three-quarters of the women knew that they should do arm exercises, keep the arm above the heart level while resting, and that blood pressure should not be measured, and jewelry not be worn. However, it was found that the percentage of women who did not know that the arm circumference should be measured at regular intervals or how to evaluate the arm circumference measurements and what to do in case of an injury was the same. It was determined that the precautions that the majority of women took in measuring lymphedema consisted of not measuring blood pressure, not wearing tight jewelry, and wearing an appropriate bra.

CONCLUSION

It is thought that patients should be informed about the development of lymphedema after breast cancer surgery because their compliance with taking the precautions will be important in reducing the incidence, degree, and effects of lymphedema.

Immediate Lymphatic Reconstruction after Axillary Lymphadenectomy: A Single-Institution Early Experience

PURPOSE

Lymphedema is progressive arm swelling from lymphatic dysfunction which can occur in 30% patients undergoing axillary dissection/radiation for breast cancer. Immediate lymphatic reconstruction (ILR) is performed in an attempt decrease the risk of lymphedema in patients undergoing axillary lymph node dissection (ALND). The purpose of this study was to assess the efficacy of ILR in preventing lymphedema rates in ALND patients.

METHODS

An institutional review board-approved retrospective review was performed of all patients who underwent ILR from 2017 to 2019. Patient demographics, comorbidities, operative and pathologic findings, number of LVAs, limb measurements, complications, and follow-up were recorded and analyzed. Student's sample t-test, Fisher's exact test, and ANOVA were used to analyze data; significance was set at p < 0.05.

RESULTS

Thirty-three patients were included in this analysis. Three patients (9.1%) developed persistent lymphedema, and two patients (6.1%) developed transient arm edema that resolved with compression and massage therapy. A significant effect was found for body mass index and the number of lymph nodes taken on the development of lymphedema (p < 0.01).

CONCLUSIONS

The rate of lymphedema in this series was 9.1%, which is an improvement from historical rates of lymphedema. Our findings support ILR as a technique that potentially decreases the incidence of lymphedema after axillary lymphadenectomy. Obesity and number of lymph nodes removed were significant predictive variables for the development of lymphedema following LVA.

The results of the intensive phase of complete decongestive therapy and the determination of predictive factors for response to treatment in patients with breast cancer related-lymphedema

BACKGROUND

Lymphedema is a common complication of breast cancer or its treatment. The gold standard treatment for lymphedema is complete decongestive therapy. There are few studies about the predictive factors for the effectiveness of complete decongestive therapy.

AIM

To evaluate the results of the intensive phase of complete decongestive therapy, and to determine the predictive factors for the response to treatment in patients with breast cancer-related lymphedema.

METHODS AND RESULTS

Fifty-seven patients with breast cancer-related lymphedema (mean age: 56.2 ± 11.2 years) who underwent complete decongestive therapy between 2014 and 2016 were evaluated retrospectively. Extremity volume was calculated using circumferential measurements and the truncated cone formula technique. Response to treatment was evaluated using the percentage reduction of excess volume formula, which was obtained by calculating the extremity volume before and after treatment. The median percentage reduction of excess volume was 27.7% (IQR,13.6-50.3). The history of skin infection was related to lower percentage reduction of excess volume (P = 0.001). Although percentage reduction of excess volume was positively correlated with education level (r = 0.286, P = 0.031), percentage reduction of excess volume was negatively correlated with lymphedema duration (r = -0.361, P = 0.006), postoperative duration (r = -0.314, P = 0.018), percentage of excess volume (r = -0.398, P = 0.002), and number of complete decongestive therapy sessions (r = -0.436, P = 0.001). Univariate and multivariate analyses showed that the independent variables for percentage reduction of excess volume were percentage of excess volume (P = 0.009) and education level (P = 0.021).

CONCLUSION

Complete decongestive therapy is an effective method in patients with breast cancer related-lymphedema. The most important predictive factors for the efficacy of treatment were found as percentage of excess volume and education level. Patients with breast cancer should be followed up regularly and receive complete decongestive therapy in the early stage of lymphedema.

Prevalence and incidence of cancer related lymphedema in low and middle-income countries: a systematic review and meta-analysis

BACKGROUND

Little is known about the prevalence and incidence in low and middle-income countries (LMICs) of secondary lymphedema due to cancer. The purpose of the study is to estimate the prevalence and incidence in LMICs of secondary lymphedema related to cancer and/or its treatment(s) and identify risk factors.

METHOD

A systematic review and meta-analysis was conducted. Medline, EMBASE and CINAHL were searched in June 2019 for peer-reviewed articles that assessed prevalence and/or incidence of cancer-related lymphedema in LMICs. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Prevalence Studies. Estimates of pooled prevalence and incidence estimates were calculated with 95% confidence intervals (CI), with sub-group analyses grouping studies according to: country of origin, study design, risk of bias, setting, treatment, and lymphedema site and measurement. Heterogeneity was measured using X2 and I2, with interpretation guided by the Cochrane Handbook for Systematic Reviews.

RESULTS

Of 8766 articles, 36 were included. Most reported on arm lymphedema secondary to breast cancer treatment (n = 31), with the remainder reporting on leg lymphedema following gynecological cancer treatment (n = 5). Arm lymphedema was mostly measured by arm circumference (n = 16/31 studies), and leg lymphedema through self-report (n = 3/5 studies). Eight studies used more than one lymphedema measurement. Only two studies that measured prevalence of leg lymphedema could be included in a meta-analysis (pooled prevalence =10.0, 95% CI 7.0-13.0, I2 = 0%). The pooled prevalence of arm lymphedema was 27%, with considerable heterogeneity (95% CI 20.0-34.0, I2 = 94.69%, n = 13 studies). The pooled incidence for arm lymphedema was 21%, also with considerable heterogeneity (95% CI 15.0-26.0, I2 = 95.29%, n = 11 studies). There was evidence that higher body mass index (> 25) was associated with increased risk of arm lymphedema (OR: 1.98, 95% CI 1.45-2.70, I2 = 84.0%, P < 0.0001, n = 4 studies).

CONCLUSION

Better understanding the factors that contribute to variability in cancer-related arm lymphedema in LMICs is an important first step to developing targeted interventions to improve quality of life. Standardising measurement of lymphedema globally and better reporting would enable comparison within the context of information about cancer treatments and lymphedema care.

Relationship between perimetric increase and fluoroscopic pattern type in secondary upper limb lymphedema observed by Indocyanine green lymphography

To ascertain the relationship between the perimetric differences obtained between the limbs and the type of fluoroscopic pattern observed by Indocyanine green (ICG) lymphography in patients with upper limb lymphedema.A correlational descriptive study was carried out in 19 patients with upper limb lymphedema secondary to breast cancer. The perimetric increase was recorded in 11 anatomical regions after ICG injection, fluoroscopic patterns were identified using an infrared camera. The ICG patterns were categorized into worse (stardust, diffuse) or better (linear, splash) patterns.The pattern coincidence between the anterior and posterior regions of the edematous extremities was 45%. At the wrist level, a difference of 2 cm was associated with the presence of a worse fluoroscopic pattern, whereas perimeter differences of 4.25 cm in the elbow and 2.25 cm in the arm (12 cm from the epicondyle) were associated with the presence of a better fluoroscopic pattern.The perimetric differences observed between the healthy and affected upper limbs in 4 specific anatomical areas allowed us to predict the type of fluoroscopic pattern. ICG lymphography has facilitated the study of the posterior regions of edema, which are difficult to visualize using other imaging techniques.

The Role of Lymphatic Vascular Function in Metabolic Disorders

In addition to its roles in the maintenance of interstitial fluid homeostasis and immunosurveillance, the lymphatic system has a critical role in regulating transport of dietary lipids to the blood circulation. Recent work within the past two decades has identified an important relationship between lymphatic dysfunction and patients with metabolic disorders, such as obesity and type 2 diabetes, in part characterized by abnormal lipid metabolism and transport. Utilization of several genetic mouse models, as well as non-genetic models of diet-induced obesity and metabolic syndrome, has demonstrated that abnormal lymphangiogenesis and poor collecting vessel function, characterized by impaired contractile ability and perturbed barrier integrity, underlie lymphatic dysfunction relating to obesity, diabetes, and metabolic syndrome. Despite the progress made by these models, the contribution of the lymphatic system to metabolic disorders remains understudied and new insights into molecular signaling mechanisms involved are continuously developing. Here, we review the current knowledge related to molecular mechanisms resulting in impaired lymphatic function within the context of obesity and diabetes. We discuss the role of inflammation, transcription factor signaling, vascular endothelial growth factor-mediated signaling, and nitric oxide signaling contributing to impaired lymphangiogenesis and perturbed lymphatic endothelial cell barrier integrity, valve function, and contractile ability in collecting vessels as well as their viability as therapeutic targets to correct lymphatic dysfunction and improve metabolic syndromes.

Informational Needs in Patients With Breast Cancer With Lymphedema: Is It Important?

Introduction

Lymphedema is one of the complications of breast cancer treatment. It has no cure yet and can affect the quality of life. This study aimed to identify and investigate informational needs, preferred delivery methods, and time of receiving information about lymphedema for these patients.

Methods

One hundred participants were recruited through Lymphedema Clinic in Motamed Cancer Institute in Tehran, Iran, through convenience sampling and were asked to complete a self-administered survey. Data collection took place on all opening days between October 2018 and mid-March 2019.

Results

Most of the participants were above 40 years, have a diploma, homemaker, and the average income of most of the participants (57.2%) was low. The importance of having lymphedema information was very high for them. Most of them wanted detailed information at diagnosis of breast cancer. The preferred information of delivery methods were private sessions and social networks.

Conclusions

Patients with breast cancer who have lymphedema have high needs as regards concise lymphedema information. Private sessions with physicians and social networks can provide detailed information for them.

The Adventure of Axillary Treatment in Early Stage Breast Cancer

Axillary lymph node dissection (ALND) which was an essential part of breast cancer treatment and the gold standard in evaluation of the status of axillary lymph node had notorious with increased arm morbidity and reduction of quality of life. Sentinel lymph node biopsy (SLNB) accurately stages the axilla in early breast cancer and ALND is omitted in SLNB negative patients. In patients with positive SLNB the omission of ALND with or without replacement of axillary radiotherapy has also been recommended by guidelines. The neoadjuvant chemotherapy (NAC) which has been increasingly used for large breast cancers to downstage the tumours for allowing breast conserving surgery and decreasing mastectomy rate has also been used in axillary node positive patients to reduce the need for ALND. The issues surrounding the treatment of axilla in patients treated with NAC; application and false negative rate of SLNB, number of identified sentinel lymph nodes, and axillary radiotherapy instead of ALND are currently the discussed and practiced hot topics. The quests for decreasing arm morbidity without compromising outcome in breast cancer treatment which have begun with the invention of SLNB continue for axilla conserving surgery. This article reviews the adventure of axillary treatment in breast cancer patients treated with or without NAC.

"Pleurex Desalination" in Malignancy-related Ascites: A Novel Mechanism of Hyponatremia

OBJECTIVE

Pleurex catheters are a form of palliative therapy for patients, offering relief from symptomatic ascites while also affording greater independence and flexibility; however, aggressive drainage can lead to significant total body sodium losses. We describe the course of patients with "Pleurex desalination," an under-appreciated cause of hypovolemic hyponatremia, highlighting its unique pathophysiology and providing recommendations on how to manage these complex patients.

PATIENTS AND METHODS

We included representative patients with "Pleurex desalination" who were evaluated and treated by the renal consult service at Brigham and Women's between 2017 and 2019.

RESULTS

We identified 3 patients who were hospitalized with "Pleurex desalination" and had complete data on serum and urine studies, as well as treatment course. We demonstrate that patients with "Pleurex desalination" were removing up to 1 to 2 L of ascitic fluid a day and were admitted with signs and symptoms of profound hypovolemia and hyponatremia. Patients worsened with administration of diuretics and salt restriction and improved with aggressive fluid resuscitation in the form of hypertonic saline, normal saline, and/or intravenous albumin.

CONCLUSION

"Pleurex desalination" is an under-recognized cause of hyponatremia; at-risk patients require close observation and periodic resuscitation with intravenous, volume-expanding fluids.

LIMPRINT Study: The Turkish Experience

Background: Lymphedema and chronic edema is a major health care problem in both developed and nondeveloped countries The Lymphoedema Impact and Prevelance - International (LIMPRINT) study is an international health service-based study to determine the prevalence and functional impact in adult populations of member countries of the International Lymphoedema Framework (ILF). Methods and Results: A total of 1051 patients from eight centers in Turkey were recruited using the LIMPRINT study protocol. Data were collected using the core and module tools that assess the demographic and clinical properties as well as disability and quality of life (QoL). Most of the Turkish patients were recruited from specialist lymphedema services and were found to be women, housewives, and having secondary lymphedema because of cancer treatment. The duration of lymphedema was commonly <5 years and most of them had International Society of Lymphology (ISL) grade 2 lymphedema. Cellulitis, infection, and wounds were uncommon. The majority of patients did not get any treatment or advice before. Most of the patients had impaired QoL and decreased functionality, but psychological support was neglected. Although most had social health security access to lymphedema centers, nevertheless access seemed difficult because of distance and cost. Conclusion: The study has shown the current status and characteristics of lymphedema patients, treatment conditions, the unmet need for the diagnosis and treatment, as well as burden of the disease in both patients and families in Turkey. National health policies are needed for the prevention, diagnosis, and treatment in Turkey that utilize this informative data.

Dorsal Wrist Placement for Vascularized Submental Lymph Node Transfer Significantly Improves Breast Cancer-Related Lymphedema

Background

Vascularized submental lymph node flap transfer to the wrist is an effective treatment for breast cancer-related lymphedema. Dorsal placement was hypothesized to offer superior outcomes due to favorable venous drainage; however, the flap is more visible in this position compared with the volar side and was a cosmetic concern for patients. This study compared the treatment response of breast cancer-related lymphedema with the placement of vascularized submental lymph node flaps at the wrist, between dorsal and volar recipient sites.

Methods

A retrospective longitudinal study examined 15 patients receiving vascularized submental lymph node flaps at the wrist performed by a single surgeon with a mean follow-up of 17 months. Clinical and biometric analyses, including quality of life questionnaires, circumference measurements, and number of infections were conducted.

Results

All patients showed improvements in quality of life, reduced episodes of cellulitis, and reduced limb circumference measurements compared with preoperative data. Dorsal placement (n = 7) delivered significant reductions in limb circumference at all levels after 1 year (P = 0.04) and in overall function domains in the Lymphedema Specific Quality of Life Questionnaires (P = 0.04) compared with volar placement (n = 8). Venous outflow was greater in the dorsal recipient veins (P < 0.0001).

Conclusions

Patients electing to undergo vascularized lymph node transfer to the wrist should be aware that when both options are effective, dorsal placement offers improvement in outcomes despite reduced cosmesis. These results have been incorporated into an evidence-based treatment algorithm that can inform the patient and physician on the decision-making in the breast and plastic surgical spheres.

Moxibustion as a Therapy for Breast Cancer-Related Lymphedema in Female Adults: A Preliminary Randomized Controlled Trial

Objective: To evaluate the effect of moxibustion on relieving breast cancer-related lymphedema. Materials and Methods: A randomized controlled trial was conducted in our institution from March 2016 to March 2017. All patients (N = 48) with cancer-related lymphedema were allocated to 2 groups: a treatment group, in which moxibustion was performed, and a control group, in which pneumatic circulation was performed with compression garments worn every day. Therapeutic efficacy was evaluated by measuring arm circumference (wrist crease, 10 cm proximal to wrist crease, elbow crease, and 10 cm proximal to elbow crease) and determining the Revised Piper Fatigue Scale score and Visual Analog Scale score for swelling before and after treatment. Results: All patients were treated for 4 consecutive weeks. Compared with 0 week after treatment, the affected-side arm circumference after 4 weeks' treatment decreased in both treatment and control groups; the difference value in the treatment group was superior to that in the control group. Compared with the controls, moxibustion resulted in a lower Visual Analog Scale score. The Revised Piper Fatigue total scores were improved in both the moxibustion and control group, and there was no significant difference between the 2 groups. Moxibustion reduced the behavioral, sensory, emotional, and cognitive Revised Piper Fatigue scores, but only the behavioral and sensory scores improved in the control group. Conclusion: Moxibustion has potential effect on breast cancer-related lymphedema. We present promising preliminary data for larger randomized trials to enable accurate evaluation of moxibustion as a lymphedema treatment.

Lymphoedema After Breast Cancer Treatment is Associated With Higher Body Mass Index: A Systematic Review and Meta-Analysis

Background:

Excess body weight has been identified as an important risk factor for lymphoedema following breast cancer treatment, however it remains unclear how much risk increases as weight increases. We conducted a meta-analysis to assess the relationship between body mass index (BMI) and risk of lymphoedema in breast cancer patients, and to estimate the level of risk by BMI category.

Methods:

We conducted a systematic search of all articles published through May 2018 in PubMed and the Cochrane library. Studies that included data on BMI and lymphoedema in breast cancer patients were included in the meta-analysis. We compared risk of lymphoedema in BMI groups as: BMI<25 versus BMI≥25, BMI<25 versus BMI≥30, BMI≥25 to <30 versus BMI≥30, BMI<30 versus BMI≥30, BMI<25 versus BMI≥25 to BMI<30.

Results:

After exclusion of ineligible studies, 57 studies were included in the meta-analysis. The mean difference in BMI between patients with lymphoedema compared to those without lymphoedema was 1.7 (95% CI, 1.3–2.2). Compared to patients with a BMI<25, risk of lymphoedema was higher in those with a BMI >25 to <30 (odds ratio [OR] 1.3; 95% CI, 1.2 to 1.5), a BMI≥25 (OR 1.7; 95% CI, 1.5 to 1.9), or a BMI≥30 (OR 1.9; 95% CI, 1.6 to 2.4). Compared to patients with a BMI of >25 to <30, risk of lymphoedema was higher in patients with a BMI>30 (OR 1.5; 95% CI,1.4 to 1.8).

Conclusion:

Excess body weight is a risk factor for lymphoedema following treatment of breast cancer, with the magnitude of risk increasing across higher categories of BMI.

Understanding Patient Expectations of Lymphedema Surgery

BACKGROUND

Patients with lymphedema refractory to medical treatment often have unrealistic expectations for lymphedema surgery. The purpose of this study was to assess patient expectations following lymphedema surgery.

METHODS

Patients presenting to the clinic for initial evaluation for lymphedema surgery were offered to complete a survey designed to evaluate their expectations for limb appearance, limb function, and overall well-being following lymphedema surgery. The patients were instructed to score each item using a five-point scale for improvement. A mean expectation score was calculated, which was then used to estimate the effects of preoperative variables on patients expectations using multiple regression analysis.

RESULTS

A total of 21 women and two men with a mean age of 60 years completed the survey. The upper limbs were affected in 10 patients and the lower limbs were affected in 13 patients. Physicians were the initial source of information about lymphedema surgery as a potential treatment option in 10 patients (43 percent), and a majority of the patients [n = 15 (65.2 percent)] thought that the physicians had fair or poor knowledge about lymphedema surgery. Significant or complete improvement was expected by 43.4 to 73.9 percent of patients. Patients' level of education, the disease duration, and the initial source of information about lymphedema surgery had a statistically significant impact on patients' expectations.

CONCLUSIONS

Early data suggest that most patients learn about lymphedema surgery from nonphysicians, with many expecting complete or significant improvement of lymphedema-associated symptoms with surgery. These findings emphasize the importance of addressing patient expectations and providing appropriate counseling before surgery.

Lymphedema diagnosis, treatment, and follow-up from the view point of physical medicine and rehabilitation specialists

Lymphedema is an incurable, debilitating and progressive condition, leading to physical and psychosocial consequences for the patients, if left untreated. The Physical Medicine and Rehabilitation (PMR) specialist is responsible for the differential diagnosis and evaluation of the patient to tailor management and rehabilitation strategies. Therefore, the PMR specialist must have knowledge and education on the diagnosis of disease and possible complications as well as evaluation, treatment and follow-up of the patient. In this review, the pathophysiology, epidemiology, and diagnostic and therapeutic approaches of lymphedema as well as preventive strategies and follow-up strategies are discussed in the light of the current literature.

Metastatic breast cancer patients' expectations and priorities for symptom improvement

PURPOSE

Little research has examined cancer patients' expectations, goals, and priorities for symptom improvement. Thus, we examined these outcomes in metastatic breast cancer patients to provide patients' perspectives on clinically meaningful symptom improvement and priorities for symptom management.

METHODS

Eighty women with metastatic breast cancer participated in a survey with measures of comorbidity, functional status, engagement in roles and activities, distress, quality of life, and the modified Patient-Centered Outcomes Questionnaire that focused on 10 common symptoms in cancer patients.

RESULTS

On average, patients reported low to moderate severity across the 10 symptoms and expected symptom treatment to be successful. Patients indicated that a 49% reduction in fatigue, 48% reduction in thinking problems, and 43% reduction in sleep problems would represent successful symptom treatment. Cluster analysis based on ratings of the importance of symptom improvement yielded three clusters of patients: (1) those who rated thinking problems, sleep problems, and fatigue as highly important, (2) those who rated pain as moderately important, and (3) those who rated all symptoms as highly important. The first patient cluster differed from other subgroups in severity of thinking problems and education.

CONCLUSIONS

Metastatic breast cancer patients report differing symptom treatment priorities and criteria for treatment success across symptoms. Considering cancer patients' perspectives on clinically meaningful symptom improvement and priorities for symptom management will ensure that treatment is consistent with their values and goals.

Worldwide assessment of healthcare personnel dealing with lymphoedema

BACKGROUND

Lymphoedema is a pandemic with about 250 million people suffering from this condition worldwide. Lymphatic diseases have considerable public health significance, but yet few professionals are specialised in their management causing a substantial burden on health resources.

AIMS AND OBJECTIVES

This study aims to give an overview of the approximate number of medical professionals, professional societies, institutions and companies dealing with lymphoedema in various countries. Concepts of improvement for current human resources are considered.

METHODS

An online database analysis (Google search engine and PubMed) was carried out for each country of the world. Additionally, relevant congress participant lists as well as member lists of significant medical societies and reports of the World Health Organisation were analysed.

RESULTS

Overall distribution of tertiary level professionals specialised in this field is heterogenous. A decrescent gradient of professionals can be seen between developed and developing countries and between urban and rural areas. Countries in general do not seem to have yet met the current demand for specialists at tertiary level in this field.

CONCLUSIONS

This study intends to draw attention to the current medical coverage gaps due to a low number of lymphoedema specialists at tertiary level. It wishes to start a discussion about structured reimbursement and certification of knowledge and skills that are essential incentives for experts to act as multiplicators and change the lack of care in the mid-term. Current fail prescriptions and evitable disability and sick certificates represent a high financial burden that could be reinvested in a correct management. Policy makers must focus in the two above mentioned essential measures. Medical training and the consequent development of the industry will then naturally take place, as it was the case for other professional groups in the past.

Quantitative Lymphoscintigraphy to Predict the Possibility of Lymphedema Development After Breast Cancer Surgery: Retrospective Clinical Study

Objective

To predict the probability of lymphedema development in breast cancer patients in the early post-operation stage, we investigated the ability of quantitative lymphoscintigraphic assessment.

Methods

This retrospective study included 201 patients without lymphedema after unilateral breast cancer surgery. Lymphoscintigraphy was performed between 4 and 8 weeks after surgery to evaluate the lymphatic system in the early postoperative stage. Quantitative lymphoscintigraphy was performed using four methods: ratio of radiopharmaceutical clearance rate of the affected to normal hand; ratio of radioactivity of the affected to normal hand; ratio of radiopharmaceutical uptake rate of the affected to normal axilla (RUA); and ratio of radioactivity of the affected to normal axilla (RRA). During a 1-year follow-up, patients with a circumferential interlimb difference of 2 cm at any measurement location and a 200-mL interlimb volume difference were diagnosed with lymphedema. We investigated the difference in quantitative lymphoscintigraphic assessment between the non-lymphedema and lymphedema groups.

Results

Quantitative lymphoscintigraphic assessment revealed that the RUA and RRA were significantly lower in the lymphedema group than in the non-lymphedema group. After adjusting the model for all significant variables (body mass index, N-stage, T-stage, type of surgery, and type of lymph node surgery), RRA was associated with lymphedema (odds ratio=0.14; 95% confidence interval, 0.04–0.46; p=0.001).

Conclusion

In patients in the early postoperative stage after unilateral breast cancer surgery, quantitative lymphoscintigraphic assessment can be used to predict the probability of developing lymphedema.

Evaluation of the Upper Limb Lymphatic System: A Prospective Lymphoscintigraphic Study in Melanoma Patients and Healthy Controls

BACKGROUND

Current research on the upper limb lymphatic system mainly studies breast cancer patients with unilateral lymphedema. Without preoperative lymphoscintigraphy, the contralateral limb is used as a control, assuming that it is functionally intact. Few lymphoscintigraphic studies investigate patients before any axillary surgery. The purpose of this study was to evaluate, through lymphoscintigraphy, the preoperative condition of the upper limb lymphatic system in melanoma patients and healthy controls.

METHODS

Two groups were studied: the study group (16 patients with trunk/upper limb melanoma candidates for axillary sentinel lymph node biopsy) and the control group (10 healthy volunteers). All subjects underwent upper limb lymphoscintigraphy. Lymphoscintigraphic images were classified into three patterns based on the tracer appearance time in the axillary nodes. Type I, 20 minutes; type II, 60 minutes; and type III, 120 minutes. Statistical analysis was used to assess the relationship between lymphoscintigraphic patterns and clinical variables and to compare patterns of distribution.

RESULTS

Lymphoscintigraphic patterns were asymmetric in 37.5 percent (study group) and 50 percent (control group). Type III was the most common pattern. There was no significant association between lymphoscintigraphic patterns and considered clinical variables. There was no significant difference in the lymphoscintigraphic pattern distribution of the two groups (p = 0.870).

CONCLUSION

The authors' findings show wide differences and an often "slow" tracer appearance time in patients with intact lymphatic system, questioning the use of contralateral limb as control and transportation time greater than 30 minutes as criteria for identification of lymphatic alterations.

Lymphatic Drainage to the Paravertebral Lymph Nodes in Breast Cancer Patients

INTRODUCTION

Aberrant, altered, or blocked lymphatic drainage may contribute to the high recurrence rate of breast cancer. Thus, an efficient evaluation of lymphatic drainage from the breasts and/or upper limbs is essential in the management of lymphedema and in ipsilateral primary or contralateral recurrent breast cancer patients. There are very few reports of lymphatic drainage to the paravertebral lymph nodes in patients with a lymphedema after breast cancer surgery with or without reconstruction.

METHODS

We used lymphoscintigraphy to examine lymphatic drainage in a case series.

RESULTS

We observed five patients with upper limb and/or mammary lymphedema (after breast cancer surgery with or without reconstruction) who had lymphatic drainage from the upper limb or breast to the posterior intercostal and/or paravertebral lymph nodes. One patient also presented with nodal relapse at the time of our investigation.

CONCLUSIONS

The cases from this study demonstrate the unusual, and mostly unrecognized, lymphatic drainage pathways toward lymph nodes, which may be at risk for further evolution of breast cancer.

Latissimus dorsi flap with vascularized lymph node transfer for lymphedema treatment: Technique, outcomes, indications and review of literature

BACKGROUND AND OBJECTIVES

One of the surgical treatment options for lymphedema is vascularized lymph node transfer (VLNT). We present our experience with latissimus dorsi (LD) flap based VLNT for lymphedema treatment.

METHODS

We reviewed 14 consecutive patients treated with pedicled or free LD VLNT between 2014 and 2016 for recalcitrant upper or lower extremity lymphedema. Seven patients underwent lymphovenous bypass in addition to LD VLNT. Limb volume and quality of life scores using the Lymphedema Life Impact Scale (LLIS) were analyzed for quantitative and qualitative assessment.

RESULTS

Mean duration of lymphedema was 69 months (range 24-124 months). Follow-up ranged from 3 to 12 months (mean 6.7 month). Major complications included one free flap loss and one reoperation for thrombosis. Mean preoperative volume differential between normal and affected limb was 35% (range 3-87%). Volume differential reduction was 48%, 28%, and 46% at 3, 6, and 12 months, respectively. The LLIS score improved from mean of 46.8 before surgery to a mean of 38.6 at 12 month, demonstrating improvement in quality of life.

CONCLUSIONS

The LD VLNT provides a viable option for treatment of UE and LE lymphedema in selected patients. J. Surg. Oncol. 2017;115:72-77. © 2016 Wiley Periodicals, Inc.

Management of the Regional Lymph Nodes in Early-Stage Breast Cancer

The management of regional nodes in early-stage invasive breast cancer continues to evolve. Improved systemic therapy has contributed to better local regional control, and at the same time it has drawn more attention to its importance. Axillary dissections have decreased, in part because of the increased efficacy of systemic therapy, and also because adjuvant therapy decisions are increasingly driven by biologic characterization of the tumor rather than pathologic nodal information. The trend toward less axillary surgery and a shift toward increased reliance on systemic and radiation therapy to address nodal disease has created interesting questions that were subsequently addressed in recent trials. We review the controversies in regional nodal management, the benefits of current treatment paradigms, the balance between less surgery and more radiation, and the potential tradeoffs vs toxicity.

Manual Lymphatic Drainage Therapy

Health care providers are constantly confronted with the challenge of providing quality health care while at the same time containing escalating costs. Incorporating complementary therapies into standard health care practices can assist in escalating the healing process, enhancing general wellness, focusing on prevention, and promoting a better quality of life. This article discusses manual lymphatic drainage therapy and identifies the value of as well the indications for the therapy. A brief overview of the lymphatic system is included.

The Effect of Education on Upper Extremity Function in Patients with Lymphedema after Breast Cancer Treatments

BACKGROUND

The aim of this study was to evaluate the effects of education on the upper extremity functions of patients with lymphedema (LE) after breast cancer treatments.

METHODS

Thirty-eight patients with LE after breast cancer treatments participated in the study. The patients were separated into two groups. Group 1 (n = 19) was educated about the causes and symptoms of LE and the methods for minimizing complications from LE, such as skin care, changes that must be made in daily life activities, exercises, and protective clothing. Group 2 (n = 19) was treated through standard means (surgical, chemotherapy, radiotherapy). A universal goniometer was used to assess the range of motion of the upper extremity of the patients. The Disabilities of the Arm, Shoulder and Hand questionnaire (DASH) and the Shoulder Pain and Disability Index (SPADI) were used to assess shoulder function. The measures were carried out once by the same physiotherapist. The chi-square and Mann-Whitney U tests were used to analyze the data.

RESULTS

Group 1, educated about LE, performed better than the other group in shoulder flexion range. When shoulder abduction, internal-external rotation, and elbow flexion motions were compared by using the DASH and SPADI, no significant difference was observed between the groups (p > 0.05). However, when shoulder function was compared, Group 1 was better. There was no significant difference between the groups when the severity of LE was compared.

CONCLUSION

This study underscores the need to develop and implement strategies for LE prevention and education for all breast cancer patients.

Immediate Implant Reconstruction Is Associated With a Reduced Risk of Lymphedema Compared to Mastectomy Alone: A Prospective Cohort Study

OBJECTIVE

We sought to determine the risk of lymphedema associated with immediate breast reconstruction compared to mastectomy alone.

BACKGROUND

Immediate breast reconstruction is increasingly performed at the time of mastectomy. Few studies have examined whether breast reconstruction impacts development of lymphedema.

METHODS

A total of 616 patients with breast cancer who underwent 891 mastectomies between 2005 and 2013 were prospectively screened for lymphedema at our institution, with 22.2 months' median follow-up. Mastectomies were categorized as immediate implant, immediate autologous, or no reconstruction. Arm measurements were performed preoperatively and during postoperative follow-up using a Perometer. Lymphedema was defined as 10% or more arm volume increase compared to preoperative. Kaplan-Meier and Cox regression analyses were performed to determine lymphedema rates and risk factors.

RESULTS

Of 891 mastectomies, 65% (580/891) had immediate implant, 11% (101/891) immediate autologous, and 24% (210/891) no reconstruction. The two-year cumulative incidence of lymphedema was as follows: 4.08% [95% confidence interval (CI): 2.59-6.41%] implant, 9.89% (95% CI: 4.98-19.1%) autologous, and 26.7% (95% CI: 20.4-34.4%) no reconstruction. By multivariate analysis, immediate implant [hazards ratio (HR): 0.352, P < 0.0001] but not autologous (HR: 0.706, P = 0.2151) reconstruction was associated with a significantly reduced risk of lymphedema compared to no reconstruction. Axillary lymph node dissection (P < 0.0001), higher body mass index (P < 0.0001), and greater number of nodes dissected (P = 0.0324) were associated with increased lymphedema risk.

CONCLUSIONS

This prospective study suggests that in patients for whom implant-based reconstruction is available, immediate implant reconstruction does not increase the risk of lymphedema compared to mastectomy alone.

The need for preoperative baseline arm measurement to accurately quantify breast cancer-related lymphedema

Breast cancer-related lymphedema (BCRL) is a feared outcome of breast cancer treatment, yet the push for early screening is hampered by a lack of standardized quantification. We sought to determine the necessity of preoperative baseline in accounting for temporal changes of upper extremity volume. 1028 women with unilateral breast cancer were prospectively screened for lymphedema by perometry. Thresholds were defined: relative volume change (RVC) ≥10 % for clinically significant lymphedema and ≥5 % including subclinical lymphedema. The first postoperative measurement (pseudo-baseline) simulated the case of no baseline. McNemar's test and binomial logistic regression models were used to analyze BCRL misdiagnoses. Preoperatively, 28.3 and 2.9 % of patients had arm asymmetry of ≥5 and 10 %, respectively. Without baseline, 41.6 % of patients were underdiagnosed and 40.1 % overdiagnosed at RVC ≥ 5 %, increasing to 50.0 and 54.8 % at RVC ≥ 10 %. Increased pseudo-baseline asymmetry, increased weight change between baselines, hormonal therapy, dominant use of contralateral arm, and not receiving axillary lymph node dissection (ALND) were associated with increased risk of underdiagnosis at RVC ≥ 5 %; not receiving regional lymph node radiation was significant at RVC ≥ 10 %. Increased pseudo-baseline asymmetry, not receiving ALND, and dominant use of ipsilateral arm were associated with overdiagnosis at RVC ≥ 5 %; increased pseudo-baseline asymmetry and not receiving ALND were significant at RVC ≥ 10 %. The use of a postoperative proxy even early after treatment results in poor sensitivity for identifying BCRL. Providers with access to patients before surgery should consider the consequent need for proper baseline, with specific strategy tailored by institution.

Impact of Ipsilateral Blood Draws, Injections, Blood Pressure Measurements, and Air Travel on the Risk of Lymphedema for Patients Treated for Breast Cancer

PURPOSE

The goal of this study was to investigate the association between blood draws, injections, blood pressure readings, trauma, cellulitis in the at-risk arm, and air travel and increases in arm volume in a cohort of patients treated for breast cancer and screened for lymphedema.

PATIENTS AND METHODS

Between 2005 and 2014, patients undergoing treatment of breast cancer at our institution were screened prospectively for lymphedema. Bilateral arm volume measurements were performed preoperatively and postoperatively using a Perometer. At each measurement, patients reported the number of blood draws, injections, blood pressure measurements, trauma to the at-risk arm(s), and number of flights taken since their last measurement. Arm volume was quantified using the relative volume change and weight-adjusted change formulas. Linear random effects models were used to assess the association between relative arm volume (as a continuous variable) and nontreatment risk factors, as well as clinical characteristics.

RESULTS

In 3,041 measurements, there was no significant association between relative volume change or weight-adjusted change increase and undergoing one or more blood draws (P = .62), injections (P = .77), number of flights (one or two [P = .77] and three or more [P = .91] v none), or duration of flights (1 to 12 hours [P = .43] and 12 hours or more [P = .54] v none). By multivariate analysis, factors significantly associated with increases in arm volume included body mass index ≥ 25 (P = .0236), axillary lymph node dissection (P < .001), regional lymph node irradiation (P = .0364), and cellulitis (P < .001).

CONCLUSION

This study suggests that although cellulitis increases risk of lymphedema, ipsilateral blood draws, injections, blood pressure readings, and air travel may not be associated with arm volume increases. The results may help to educate clinicians and patients on posttreatment risk, prevention, and management of lymphedema.
