Meta-Analysis
BACKGROUND
The purpose of this systematic review update and meta-analysis was to analyze resistance exercise (RE) intervention trials in breast cancer survivors (BCS) regarding their effect on breast cancer-related lymphedema (BCRL) status and upper and lower extremity strength.
METHODS
Systematic literature search was conducted utilizing PubMed, MEDLINE, and Embase databases. Any exercise intervention studies-both randomized controlled and uncontrolled-which assessed the effects of RE on BCRL in BCS in at least one intervention group published between 1966 and 31st January 2020 were included. Included articles were analyzed regarding their level of evidence and their methodological quality using respective tools for randomized and nonrandomized trials of the Cochrane collaboration. Meta-analysis for bioimpedance spectroscopy (BIS) values as well as upper and lower extremity strength was conducted.
RESULTS
Altogether, 29 studies were included in the systematic review. Results of six studies with altogether twelve RE intervention groups could be pooled for meta-analysis of the BCRL. A significant reduction of BCRL after RE was seen in BIS values (95% CI - 1.10 [- 2.19, - 0.01] L-Dex score). Furthermore, strength results of six studies could be pooled and meta-analysis showed significant improvements of muscular strength in the upper and lower extremities (95% CI 8.96 [3.42, 14.51] kg and 95% CI 23.42 [11.95, 34.88] kg, respectively).
CONCLUSION
RE does not have a systematic negative effect on BCRL and, on the contrary, potentially decreases it.

Meta-Analysis Review
AIM
To determine the effective exercise methods for different complications of breast cancer patients after surgery.
DESIGN
Systematic review and meta-analysis.
METHODS
A comprehensive electronic search was carried out with no time limit until May 2020. Studies must have been randomized controlled trials of patients after breast cancer surgery, without limit to the way of exercise. Literature quality was evaluated by the modified Jadad scale. The meta-analysis was conducted with CMA2.0 software.
RESULTS
Aerobic exercise reduced the intensity of the pain (MD = -1.043), improved shoulder flexion (MD = 3.398) and internal rotation range (MD = 3.868), lessened upper limb dysfunction (MD = -5.231) and improved muscle strength during flexion (MD = 1.076) and abduction (MD = 0.991). Shoulder elbow movement improved the range of shoulder external rotation (MD = 2.691) and reduced the incidence of arm lymphedema (RR = 0.343). Anti-resistance exercise also lessened upper limb dysfunction (MD = - 4.094).

Review
BACKGROUND
Water therapies as hydrotherapy, balneotherapy or aqua therapy are often used in the relief of disease- and treatment-associated symptoms of cancer patients. Yet, a systematic review for the evidence of water therapy including all cancer entities has not been conducted to date.
PURPOSE
Oncological patients often suffer from symptoms which in patients with other diseases are successfully treated with water therapy. We want to gather more information about the benefits and risks of water therapy for cancer patients.
METHOD
In May 2020, a systematic search was conducted searching five electronic databases (Embase, Cochrane, PsychInfo, CINAHL and PubMed) to find studies concerning the use, effectiveness and potential harm of water therapy on cancer patients.
RESULTS
Of 3165 search results, 10 publications concerning 12 studies with 430 patients were included in this systematic review. The patients treated with water therapy were mainly diagnosed with breast cancer. The therapy concepts included aqua lymphatic therapy, aquatic exercises, foot bathes and whole-body bathes. Outcomes were state of lymphedema, quality of life, fatigue, BMI, vital parameters, anxiety and pain. The quality of the studies was assessed with the AMSTAR2-instrument, the SIGN-checklist and the IHE-Instruments. The studies had moderate quality and reported heterogeneous results. Some studies reported significantly improved quality of life, extent of lymphedema, neck and shoulder pain, fatigue and BMI while other studies did not find any changes concerning these endpoints.
CONCLUSION
Due to the very heterogeneous results and methodical limitations of the included studies, a clear statement regarding the effectiveness of water therapy on cancer patients is not possible.

The aim of this study was to identify the characteristics of resistance training (RT) programs for breast cancer survivors (BCS). A systematic review of the literature was performed using PubMed, Medline, Science Direct, the Cochrane Breast Cancer Specialised Register of the Cochrane Library, the Physiotherapy Evidence Database (PEDro), and Scopus, with the aim of identifying all published studies on RT and BCS from 1 January 1990 to 6 December 2019, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The risk of bias in the studies was assessed using the revised Cochrane Risk of Bias tool (RoB 2.0). Sixteen trials were included for qualitative analysis. More than half of the trials do not adequately report the characteristics that make up the exercise program. The maximal strength was the most frequently monitored manifestation of strength, evaluated mainly as one-repetition maximum (1RM). Resistance training was performed on strength-training machines, twice a week, using a load between 50% and 80% of 1RM. The trials reported significant improvement in muscle strength, fatigue, pain, quality of life, and minor changes in aerobic capacity.

DISCLAIMER
This article is based on recommendations from the 12 WALT Congress, Nice, October 3-6, 2018, and a follow-up review of the existing data and the clinical observations of an international multidisciplinary panel of clinicians and researchers with expertise in the area of supportive care in cancer and/or PBM clinical application and dosimetry. This article is informational in nature. As with all clinical materials, this paper should be used with a clear understanding that continued research and practice could result in new insights and recommendations. The review reflects the collective opinion and, as such, does not necessarily represent the opinion of any individual author. In no event shall the authors be liable for any decision made or action taken in reliance on the proposed protocols.
OBJECTIVE
This position paper reviews the potential prophylactic and therapeutic effects of photobiomodulation (PBM) on side effects of cancer therapy, including chemotherapy (CT), radiation therapy (RT), and hematopoietic stem cell transplantation (HSCT).
BACKGROUND
There is a considerable body of evidence supporting the efficacy of PBM for preventing oral mucositis (OM) in patients undergoing RT for head and neck cancer (HNC), CT, or HSCT. This could enhance patients' quality of life, adherence to the prescribed cancer therapy, and treatment outcomes while reducing the cost of cancer care.
METHODS
A literature review on PBM effectiveness and dosimetry considerations for managing certain complications of cancer therapy were conducted. A systematic review was conducted when numerous randomized controlled trials were available. Results were presented and discussed at an international consensus meeting at the World Association of photobiomoduLation Therapy (WALT) meeting in 2018 that included world expert oncologists, radiation oncologists, oral oncologists, and oral medicine professionals, physicists, engineers, and oncology researchers. The potential mechanism of action of PBM and evidence of PBM efficacy through reported outcomes for individual indications were assessed.
RESULTS
There is a large body of evidence demonstrating the efficacy of PBM for preventing OM in certain cancer patient populations, as recently outlined by the Multinational Association for Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO). Building on these, the WALT group outlines evidence and prescribed PBM treatment parameters for prophylactic and therapeutic use in supportive care for radiodermatitis, dysphagia, xerostomia, dysgeusia, trismus, mucosal and bone necrosis, lymphedema, hand-foot syndrome, alopecia, oral and dermatologic chronic graft-versus-host disease, voice/speech alterations, peripheral neuropathy, and late fibrosis amongst cancer survivors.
CONCLUSIONS
There is robust evidence for using PBM to prevent and treat a broad range of complications in cancer care. Specific clinical practice guidelines or evidence-based expert consensus recommendations are provided. These recommendations are aimed at improving the clinical utilization of PBM therapy in supportive cancer care and promoting research in this field. It is anticipated these guidelines will be revised periodically.

Meta-Analysis
BACKGROUND
Studies have shown that manual lymphatic drainage (MLD) has a beneficial effect on lymphedema related to breast cancer surgery. However, whether MLD reduces the risk of lymphedema is still debated. The purpose of this systematic review and meta-analysis was to summarize the current evidence to assess the effectiveness of MLD in preventing and treating lymphedema in patients after breast cancer surgery.
METHODS
From inception to May 2019, PubMed, EMBASE, and Cochrane Library databases were systematically searched without language restriction. We included randomized controlled trials (RCTs) that compared the treatment and prevention effect of MLD with a control group on lymphedema in breast cancer patients. A random-effects model was used for all analyses.
RESULTS
A total of 17 RCTs involving 1911 patients were included. A meta-analysis of 8 RCTs, including 338 patients, revealed that MLD did not significantly reduce lymphedema compared with the control group (standardized mean difference (SMD): -0.09, 95% confidence interval (CI): [-0.85 to 0.67]). Subgroup analysis was basically consistent with the main analysis according to the research region, the publication year, the sample size, the type of surgery, the statistical analysis method, the mean age, and the intervention time. However, we found that MLD could significantly reduce lymphedema in patients under the age of 60 years (SMD: -1.77, 95% CI: [-2.23 to -1.31]) and an intervention time of 1 month (SMD: -1.77, 95% CI: [-2.23 to -1.30]). Meanwhile, 4 RCTs including, 1364 patients, revealed that MLD could not significantly prevent the risk of lymphedema (risk ratio (RR): 0.61, 95% CI: [0.29-1.26]) for patients having breast cancer surgery.
CONCLUSIONS
Overall, this meta-analysis of 12 RCTs showed that MLD cannot significantly reduce or prevent lymphedema in patients after breast cancer surgery. However, well-designed RCTs with a larger sample size are required, especially in patients under the age of 60 years or an intervention time of 1 month.

Review
Lymphedema is a chronic condition that negatively affects function and quality of life. There is currently no definitive treatment. However, some options have been proposed to mitigate its consequences. Complex Decongestive Therapy (CDT) stands out as one of the main treatment methods of choice. This systematic review aimed to evaluate the effectiveness of this technique for treating lower extremity lymphedema. The results revealed that CDT was effective in reducing the volume of affected limbs. However, some questions have not yet been answered, such as: How long do patients benefit from using CDT? and How to maintain the gains obtained? It was not possible to perform a meta-analysis because of heterogeneity, unsatisfactory methodological quality of the available studies, and the lack of a gold-standard protocol for administration of the technique. Further studies are needed to advance lymphedema research and therapy.

OBJECTIVES
Medical compression therapy is used for non-invasive treatment of venous and lymphatic diseases. Medical compression therapy-associated adverse events and contraindications have been reported, although some contraindications are theoretically based. This consensus statement provides recommendations on medical compression therapy risks and contraindications.
METHODS
A systematic literature search of medical compression therapy publications reporting adverse events up until November 2017 was performed. A consensus panel comprising 15 international experts critically reviewed the publications and formulated the recommendations.
RESULTS
Sixty-two publications reporting medical compression therapy adverse events were identified. The consensus panel issued 21 recommendations on medical compression therapy contraindications and adverse event risk mitigation, in addition to reviewing medical compression therapy use in borderline indications. The most frequently reported non-severe medical compression therapy-associated adverse events included skin irritation, discomfort and pain. Very rare but severe adverse events, including soft tissue and nerve injury, were also identified.
CONCLUSION
This consensus statement summarises published medical compression therapy-associated adverse events and contraindications, and provides guidance on medical compression therapy. Severe medical compression therapy-associated adverse events are very rarely encountered if compression is used correctly and contraindications are considered.

INTRODUCTION
One of the most common disabling complications in breast cancer (BC) patients is breast cancer-related lymphedema (BCRL), a pathological condition affecting both physical and psychological function, with detrimental consequences on health-related quality of life (HR-QoL). Rehabilitation has a key role in the comprehensive management of this condition with several studies reporting positive results after performing complex decongestive therapies (CDT) in these women. Kinesio taping (KT) is a rather recent therapeutic approach to treat BCRL, however, evidence in literature regarding its effectiveness is far from being fully characterized. Therefore, this systematic review aimed at assessing the role of KT among the CDT to treat BCRL.
EVIDENCE ACQUISITION
PubMed, Scopus, and Web of Science were systematically searched from inception until May 5, 2022 to determine randomized control trials (RCTs) reporting patients with BCRL; KT as intervention; limb volume as outcome (PROSPERO number: CRD42022349720).
EVIDENCE SYNTHESIS
Out of the documents identified, 123 were eligible for data screening, and only 7 RCTs satisfied the eligibility criteria and were included. We found that KT might have a positive effect on limb volume reduction in patients with BCRL, albeit there is little evidence for low quality of the included studies.
CONCLUSIONS
Taken together, this systematic review showed that KT did not significantly reduce the upper limb volume in BCRL women, albeit it seemed to increase the flow rate during the passive exercise. Further high-quality-studies are mandatory to improve the knowledge in order to include the KT might into a multidisciplinary rehabilitative approach for the management of BC survivors affected by lymphedema.

Review
PURPOSE OF REVIEW
Breast cancer-related lymphedema (BCRL) is a debilitating progressive disease resulting in various impairments and dysfunctions. Complete decongestive therapy embodies conservative rehabilitation treatments for BCRL. Surgical procedures performed by plastic and reconstructive microsurgeons are available when conservative treatment fails. The purpose of this systematic review was to investigate which rehabilitation interventions contribute to the highest level of pre- and post-microsurgical outcomes.
RECENT FINDINGS
Studies published between 2002 and 2022 were grouped for analysis. This review was registered with PROSPERO (CRD42022341650) and followed the PRISMA guidelines. Levels of evidence were based upon study design and quality. The initial literature search yielded 296 results, of which, 13 studies met all inclusion criteria. Lymphovenous bypass anastomoses (LVB/A) and vascularized lymph node transplant (VLNT) emerged as dominant surgical procedures. Peri-operative outcome measures varied greatly and were used inconsistently. There is a dearth of high quality literature leading to a gap in knowledge as to how BCRL microsurgical and conservative interventions complement each other. Peri-operative guidelines are needed to bridge the knowledge and care gap between lymphedema surgeons and therapists. A core set of outcome measures for BCRL is vital to unify terminological differences in the multidisciplinary care of BCRL. Complete decongestive therapy embodies conservative rehabilitation treatments for breast cancer-related lymphedema (BCRL). Surgical procedures performed by microsurgeons are available when conservative treatment fails. This systematic review investigated which rehabilitation interventions contribute to the highest level of pre- and post-microsurgical outcomes. Thirteen studies met all inclusion criteria and revealed that there is a dearth of high quality literature leading to a gap in knowledge as to how BCRL microsurgical and conservative interventions complement each other. Furthermore, peri-operative outcome measures were inconsistent. Peri-operative guidelines are needed to bridge the knowledge and care gap between lymphedema surgeons and therapists.
