Review
INTRODUCTION
Analysis of quality of life (QOL) outcomes is an important aspect of lymphedema treatment since this disease can substantially impact QOL in affected individuals. There are a growing number of studies reporting patient-reported outcomes (PROMs) for patients with lymphedema. The purpose of this study was to conduct a systematic review of outcomes and utilization of PROMs following surgical treatment of lymphedema.
METHODS
A literature search of four databases was performed up to and including March, 2019. Studies included reported on QOL outcomes after physiologic procedures, defined as either lymphovenous bypass (LVB) or vascularized lymph node transplant (VLNT), to treat upper and/or lower extremity primary or secondary lymphedema.
RESULTS
In total, 850 studies were screened-of which, 32 studies were included in this review. Lymphovenous bypass was the surgical intervention in 16 studies, VLNT in 11 studies, and both in 5 studies. Of the 32 total studies, 16 used validated survey tools. The most commonly used PROM was the lymph quality of life measure for limb lymphedema (LYMQOL) (12 studies). In the remaining four studies, the upper limb lymphedema 27 scale (ULL27), the short form 36 questionnaire (SF-36), the lymphedema functioning, disability and health questionnaire (Lymph-ICF), and lymphedema life impact scale (LLIS) were each used once. QOL improvement following surgical treatment was noted in all studies.
CONCLUSIONS
Physiologic surgical treatment of lymphedema results in improved QOL outcomes in most patients. The use of validated PROM tools is increasing but there is no current consensus on use. Future research to evaluate the psychometric properties of PROMs in lymphedema is needed to guide the development and use of lymphedema-specific tools.

Review
BACKGROUND
Lymphedema is a chronic and debilitating condition that affects many cancer survivors. Patient-reported outcome measures (PROMs) can give valuable insight into the impact of lymphedema on a patient's quality of life and can play an essential role in treatment decisions. This study aims to (1) identify PROMs used to assess health-related quality of life (HRQoL) in patients with lymphedema; and (2) assess the quality of the lymphedema-specific PROMs.
METHODS
We performed a systematic search to identify articles on lymphedema, quality of life, and PROMs. An overview was created of all PROMs used to assess HRQoL in patients with lymphedema. The methodological quality of the lymphedema-specific PROMs was assessed using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) criteria.
RESULTS
A total of 235 articles met the inclusion criteria, of which 200 described studies using one or more PROMs as an outcome measure in patients with lymphedema. The other 35 studies described the development and/or validation of a lymphedema-specific PROM. The COSMIN assessment demonstrated that none of these PROMs met all quality standards for development.
CONCLUSION
The use of PROMs in lymphedema is increasing; however, based on our findings, we cannot fully support the use of any of the existing instruments. A well-developed lymphedema-specific PROM, based on patient input, is needed to gain better insight into the impact of this condition, and can be used to measure the effect of possible medical and surgical treatments.

Meta-Analysis
The incidence of perioperative lymphatic complications after radical hysterectomy and pelvic lymphadenectomy between robotic and laparoscopic approach : a systemic review and meta-analysis.
BACKGROUND
Although many studies have reported perioperative complications after radical hysterectomy and pelvic lymph node dissection using robotic and laparoscopic approaches, the risk of perioperative lymphatic complications has not been well identified. The aim of this meta-analysis is to compare the risks of perioperative lymphatic complications after robotic radical hysterectomy and lymph node dissection (RRHND) with laparoscopic radical hysterectomy and lymph node dissection (LRHND) for early uterine cervical cancer.
MATERIALS AND METHODS
The authors searched the PubMed, Cochrane Library, Web of Science, ScienceDirect, and Google Scholar databases for studies published up to July 2022 comparing perioperative lymphatic complications after RRHND and LRHND while treating early uterine cervical cancer. Related articles and bibliographies of relevant studies were also checked. Two reviewers independently performed the data extraction.
RESULTS
A total of 19 eligible clinical trials (15 retrospective studies and 4 prospective studies) comprising 3079 patients were included in this analysis. Only 107 patients (3.48%) had perioperative lymphatic complications, of which the most common was lymphedema ( n =57, 1.85%), followed by symptomatic lymphocele ( n =30, 0.97%), and lymphorrhea ( n =15, 0.49%). When all studies were pooled, the odds ratio for the risk of any lymphatic complication after RRHND compared with LRHND was 1.27 (95% CI: 0.86-1.89; P =0.230). In the subgroup analysis, study quality, country of research, and publication year were not associated with perioperative lymphatic complications.
CONCLUSIONS
A meta-analysis of the available current literature suggests that RRHND is not superior to LRHND in terms of perioperative lymphatic complications.

Review
PURPOSE
Breast lymphoedema is a possible side effect of breast conserving surgery, but it is poorly understood. This is due, in part, to difficulty assessing the breast. This systematic review described outcome measures that quantify breast lymphoedema signs and symptoms and evaluated the measurement properties for these outcome measures.
METHOD
Seven databases were searched using terms in four categories: breast cancer, lymphoedema and oedema, clinician reported (ClinROM) and patient reported outcome measures (PROM) and psychometric and measurement properties. Two reviewers independently reviewed studies and completed quality assessments. The Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) methodology was used for studies including measurement property evidence.
RESULTS
Fifty-six papers were included with thirteen questionnaires, eight patient-reported rating scales, seven physical measures, seven clinician-rating scales and four imaging techniques used to quantify breast lymphoedema. Based on COSMIN methodology, one ClinROM had sufficient reliability, ultrasound measuring dermal thickness. Tissue dielectric constant (TDC) measuring local tissue water had promising reliability. Four questionnaires had sufficient content validity (BLYSS, BLSQ, BrEQ and LYMQOL-Breast).
CONCLUSIONS
Ultrasound is recommended to reliably assess breast lymphoedema signs. No PROM can be recommended with confidence, but BLYSS, BLSQ, BrEQ and LYMQOL-Breast are promising. Further research is recommended to improve evidence of measurement properties for outcome measures.
IMPLICATIONS FOR CANCER SURVIVORS
There are many approaches to assess breast lymphoedema, but currently, only ultrasound can be recommended for use, with others, such as TDC and questionnaires, showing promise. Further research is required for all approaches to improve evidence of measurement properties.

Review
Noonan syndrome spectrum disorders are a group of phenotypically related conditions, resembling Noonan syndrome, caused by germline pathogenic variants in genes within the Ras/mitogen-activated protein kinase (Ras/MAPK) signalling pathway. Lymphatic dysplasia with a clinical lymphatic abnormality is one of the major features. We performed a systematic review to get more insight in (1) the prevalence of clinically lymphatic abnormalities in patients with a genetically proven Noonan syndrome spectrum disorder, (2) if a genotype-lymphatic phenotype relation can be found and describe the clinical presentation and course of the lymphatic abnormality. Most studies report patients with Noonan syndrome. Prenatally, the prevalence of increased nuchal translucency differs from 7% in patients with pathogenic variant to 38% in patients with pathogenic variants, and the prevalence of pleural effusions differed from 7% in patients with pathogenic to 29% in patients with pathogenic variants. Postnatally, the prevalence of lymphedema differs from 16% in patients with pathogenic variants to 44% in patients with pathogenic variants, and the prevalence of acquired chylothorax is 4% in patients with pathogenic variants. Lymphatic abnormalities do occur in patients with cardiofaciocutaneous syndrome and Costello syndrome. In conclusion, Noonan syndrome spectrum disorders, Noonan syndrome in particular, are associated with lymphatic abnormalities. Combining the available published literature about genetically proven Noonan syndrome spectrum disorders, it appears likely that the lifetime prevalence of these abnormalities in Noonan syndrome is higher than the 20% that were generally accepted so far. This is increasingly important, because the activation of the RAS/MAPK pathway can be inhibited by RAS/MAPK inhibitors, and clinically severe lymphatic abnormalities may improve.

Review
BACKGROUND
Patient-reported outcome measures are measures of patients' health-related quality of life. They should be added to other lymphedema measurements. With an improved disease-free survival of secondary lower limb lymphedema, attention must focus on such assessments.
OBJECTIVE
The objectives of this study were to locate and critically appraise suitable patient-reported outcomes measures for lower limb lymphedemas and search for existing valid translations for native German speakers.
METHODS
A systematic literature research was conducted. 20 semantical categories for qualitative analysis were evolved. Six questionnaires available in English and some in validated translations remained for analysis.
RESULTS
Lower limb lymphedema patients experience poor quality of life, and one of the most critical denominators is skin quality. To establish skin care and prevent cellulitis, patients must learn about skin problems. Only two tools asked for past infections. This is considered crucial because of knowledge building and prophylactic behavior. Questions on movement restrictions were available in one questionnaire. As these have a close connection to one's ability to perform activities of daily life, they can affect quality of life. Afflicted patients have problems with the choice and availability of clothing. Only three questionnaires asked questions about clothing or shoes. Lymphedema patients are exposed to more psychological stress than healthy subjects, but only three questionnaires covered questions about this burden. There was a lack of reporting on psychometric data (Cronbach's alpha, intraclass correlation), which hinders the external validity. Analyzed questionnaires were available in English but only one in German.
CONCLUSIONS
The analyzed questionnaires were in English, and only one was adapted and tested for native German speakers. For clinical practice, Devoogdt's questionnaire is recommended despite some shortcomings. There is a need for validated lymphedema questionnaires in German.

Obesity and associated chronic inflammation were shown to facilitate breast cancer (BC) growth and metastasis. Leptin, adiponectin, estrogen, and several pro-inflammatory cytokines are involved in the development of obesity-driven BC through the activation of multiple oncogenic and pro-inflammatory pathways. The aim of this study was to assess the reported mechanisms of obesity-induced breast carcinogenesis and effectiveness of conventional and complementary BC therapies. We screened published original articles, reviews, and meta-analyses that addressed the involvement of obesity-related signaling mechanisms in BC development, BC treatment/prevention approaches, and posttreatment complications. PubMed, Medline, eMedicine, National Library of Medicine (NLM), and ReleMed databases were used to retrieve relevant studies using a set of keywords, including "obesity," "oncogenic signaling pathways," "inflammation," "surgery," "radiotherapy," "conventional therapies," and "diet." Multiple studies indicated that effective BC treatment requires the involvement of diet- and exercise-based approaches in obese postmenopausal women. Furthermore, active lifestyle and diet-related interventions improved the patients' overall quality of life and minimized adverse side effects after traditional BC treatment, including postsurgical lymphedema, post-chemo nausea, vomiting, and fatigue. Further investigation of beneficial effects of diet and physical activity may help improve obesity-linked cancer therapies.

Meta-Analysis Review
BACKGROUND
Axillary surgery is an established part of the management of primary breast cancer. It provides staging information to guide adjuvant therapy and potentially local control of axillary disease. Several alternative approaches to axillary surgery are available, most of which aim to spare a proportion of women the morbidity of complete axillary dissection.
OBJECTIVES
To assess the benefits and harms of alternative approaches to axillary surgery (including omitting such surgery altogether) in terms of overall survival; local, regional and distant recurrences; and adverse events.
SEARCH METHODS
We searched the Cochrane Breast Cancer Group Specialised Register, MEDLINE, Pre-MEDLINE, Embase, CENTRAL, the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov on 12 March 2015 without language restrictions. We also contacted study authors and checked reference lists.
SELECTION CRITERIA
Randomised controlled trials (RCTs) including women with clinically defined operable primary breast cancer conducted to compare axillary lymph node dissection (ALND) with no axillary surgery, axillary sampling or sentinel lymph node biopsy (SLNB); RCTs comparing axillary sampling with SLNB or no axillary surgery; RCTs comparing SLNB with no axillary surgery; and RCTs comparing ALND with or without radiotherapy (RT) versus RT alone.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed each potentially relevant trial for inclusion. We independently extracted outcome data, risk of bias information and study characteristics from all included trials. We pooled data according to trial interventions, and we used hazard ratios (HRs) for time-to-event outcomes and odds ratios (OR) for binary outcomes.
MAIN RESULTS
We included 26 RCTs in this review. Studies were at low or unclear risk of selection bias. Blinding was not done, but this was only considered a source of bias for outcomes with potential for subjectivity in measurements. We found no RCTs of axillary sampling versus SLNB, axillary sampling versus no axillary surgery or SLNB versus no axillary surgery. No axillary surgery versus ALND Ten trials involving 3849 participants compared no axillary surgery versus ALND. Moderate quality evidence showed no important differences between overall survival of women in the two groups (HR 1.06, 95% confidence interval (CI) 0.96 to 1.17; 3849 participants; 10 studies) although no axillary surgery increased the risk of locoregional recurrence (HR ranging from 1.10 to 3.06; 20,863 person-years of follow-up; four studies). It was uncertain whether no surgery increased the risk of distant metastasis compared with ALND (HR 1.06, 95% CI 0.87 to 1.30; 946 participants; two studies). Low-quality evidence indicated no axillary surgery decreased the risk of lymphoedema compared with ALND (OR 0.31, 95% CI 0.23 to 0.43; 1714 participants; four studies). Axillary sampling versus ALND Six trials involving 1559 participants compared axillary sampling versus ALND. Low-quality evidence indicated similar effectiveness of axillary sampling compared with ALND in terms of overall survival (HR 0.94, 95% CI 0.73 to 1.21; 967 participants; three studies) but it was unclear whether axillary sampling led to increased risk of local recurrence compared with ALND (HR 1.41, 95% CI 0.94 to 2.12; 1404 participants; three studies). The relative effectiveness of axillary sampling and ALND for locoregional recurrence (HR 0.74, 95% CI 0.46 to 1.20; 406 participants; one study) and distant metastasis was uncertain (HR 1.05, 95% CI 0.74 to 1.49; 406 participants; one study). Lymphoedema was less likely after axillary sampling than after ALND (OR 0.32, 95% CI 0.13 to 0.81; 80 participants; one study). SLNB versus ALND Seven trials involving 9426 participants compared SLNB with ALND. Moderate-quality evidence showed similar overall survival following SLNB compared with ALND (HR 1.05, 95% CI 0.89 to 1.25; 6352 participants; three studies; moderate-quality evidence). Differences in local recurrence (HR 0.94, 95% CI 0.24 to 3.77; 516 participants; one study), locoregional recurrence (HR 0.96, 95% CI 0.74 to 1.24; 5611 participants; one study) and distant metastasis (HR 0.80, 95% CI 0.42 to 1.53; 516 participants; one study) were uncertain. However, studies showed little absolute difference in the aforementioned outcomes. Lymphoedema was less likely after SLNB than ALND (OR ranged from 0.04 to 0.60; three studies; 1965 participants; low-quality evidence). Three studies including 1755 participants reported quality of life: Investigators in two studies found quality of life better after SLNB than ALND, and in the other study observed no difference. RT versus ALND Four trials involving 2585 participants compared RT alone with ALND (with or without RT). High-quality evidence indicated that overall survival was reduced among women treated with radiotherapy alone compared with those treated with ALND (HR 1.10, 95% CI 1.00 to 1.21; 2469 participants; four studies), and local recurrence was less likely in women treated with radiotherapy than in those treated with ALND (HR 0.80, 95% CI 0.64 to 0.99; 22,256 person-years of follow-up; four studies). Risk of distant metastasis was similar for radiotherapy alone as for ALND (HR 1.07, 95% CI 0.93 to 1.25; 1313 participants; one study), and whether lymphoedema was less likely after RT alone than ALND remained uncertain (OR 0.47, 95% CI 0.16 to 1.44; 200 participants; one study). Less surgery versus ALND When combining results from all trials, treatment involving less surgery was associated with reduced overall survival compared with ALND (HR 1.08, 95% CI 1.01 to 1.17; 6478 participants; 18 studies). Whether local recurrence was reduced with less axillary surgery when compared with ALND was uncertain (HR 0.90, 95% CI 0.75 to 1.09; 24,176 participant-years of follow up; eight studies). Locoregional recurrence was more likely with less surgery than with ALND (HR 1.53, 95% CI 1.31 to 1.78; 26,880 participant-years of follow-up; seven studies). Whether risk of distant metastasis was increased after less axillary surgery compared with ALND was uncertain (HR 1.07, 95% CI 0.95 to 1.20; 2665 participants; five studies). Lymphoedema was less likely after less axillary surgery than with ALND (OR 0.37, 95% CI 0.29 to 0.46; 3964 participants; nine studies).No studies reported on disease control in the axilla.
AUTHORS' CONCLUSIONS
This review confirms the benefit of SLNB and axillary sampling as alternatives to ALND for axillary staging, supporting the view that ALND of the clinically and radiologically uninvolved axilla is no longer acceptable practice in people with breast cancer.

BACKGROUND
Breast cancer lymphedema (BCL) is one of the most common complications of breast cancer. Common western medical treatments for BCL, such as western medicine and lymphatic drainage, are ineffective, and recurrence may easily occur, making treatment more challenging and placing a heavier burden on patients. Acupuncture therapy is commonly used to treat BCL in China, and there are many acupuncture therapies, including acupuncture, moxibustion, and the combination of acupuncture and moxibustion. Given the difference in operation difficulty, efficacy and safety of these acupuncture types, how to the most effective therapy is controversial. Therefore, the purpose of this study was to compare the efficacy and safety of different acupuncture and moxibustion methods, so as to provide guidance for clinical practice.
METHODS
The PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang, VIP, and SinoMed databases were searched to September 30, 2022. Participants were diagnosed with BCL. Acupuncture was used in the intervention group, and other acupuncture were used in the control group. Outcomes included arm circumference, visual analogue scale (VAS), and safety evaluation. Risk of Bias Assessment Tool 2 (ROB2) was used to assess the risk of bias, Stata 16 was used for network meta-analysis.
RESULTS
A total of 7 studies were included, with 422 patients. The interventions included fire acupuncture, acupuncture (face), moxa-moxibustion, heat-sensitive moxibustion, moxibustion [traditional Chinese medicine (TCM)], acupuncture combine with moxibustion, acupoint application. The risk of overall bias was low or some concerns. The meta-analysis showed that: (I) arm circumference: acupuncture combined with moxibustion was superior to acupoint application [mean difference (MD) =-0.54; 95% confidence interval (CI): (-0.67, -0.41); P<0.05]. The surface under the cumulative ranking probability area (SUCRA) ranking results showed that acupuncture combined with moxibustion may be the optimal method. (II) VAS: acupuncture (face) was more effective than acupuncture (body) [MD =-0.85; 95% CI: (-1.09, -0.61); P<0.01]. The SUCRA ranking results showed that acupuncture (face) had the best effect.
CONCLUSIONS
Based on the current evidence, acupuncture and moxibustion is of great efficacy and safety for the treatment of BCL. Acupuncture combined with moxibustion is the most effective in reducing the arm circumference, and acupuncture (face) is of the greatest analgesic effect.

Review
BACKGROUND
Secondary lymphedema is a common complication after surgical or radiotherapeutic cancer treatment. (Micro) surgical intervention such as lymphovenous bypass and vascularized lymph node transfer is a possible solution in patients who are refractory to conventional treatment. Adequate imaging is needed to identify functional lymphatic vessels and nearby veins for surgical planning.
METHODS
A systematic literature search of the Embase, MEDLINE ALL via Ovid, Web of Science Core Collection and Cochrane CENTRAL Register of Trials databases was conducted in February 2022. Studies reporting on lymphatic vessel detection in healthy subjects or secondary lymphedema of the limbs or head and neck were analyzed.
RESULTS
Overall, 129 lymphatic vessel imaging studies were included, and six imaging modalities were identified. The aim of the studies was diagnosis, severity staging, and/or surgical planning.
CONCLUSION
Due to its utility in surgical planning, near-infrared fluorescence lymphangiography (NIRF-L) has gained prominence in recent years relative to lymphoscintigraphy, the current gold standard for diagnosis and severity staging. Magnetic resonance lymphography (MRL) gives three-dimensional detailed information on the location of both lymphatic vessels and veins and the extent of fat hypertrophy; however, MRL is less practical for routine presurgical implementation due to its limited availability and high cost. High frequency ultrasound imaging can provide high resolution imaging of lymphatic vessels but is highly operator-dependent and accurate identification of lymphatic vessels is difficult. Finally, photoacoustic imaging (PAI) is a novel technique for visualization of functional lymphatic vessels and veins. More evidence is needed to evaluate the utility of PAI in surgical planning.
