Background: Lymphedema is a common breast cancer side effect, with an average incidence of 30%. The gold standard conservative treatment for lymphedema is complex decongestive therapy (CDT), which includes manual lymphatic drainage, compression therapy, skin care, and exercise. Lymphovenular anastomosis (LVA) is a microsurgical technique that intends to redirect excess lymphatic fluid to the venous circulation; this procedure is usually performed when conservative treatment fails. Therefore, the objective of this study is to evaluate the effectiveness of LVA and CDT for the treatment of breast cancer-related lymphedema (BCRL). Methods and Results: The search was performed in CENTRAL, MEDLINE, Embase, PsycINFO, SCOPUS, and LILACS. Inclusion criteria were (1) population: women with BCRL; (2) intervention: treated with LVA and CDT; and (3) outcome: primary outcome was lymphedema reduction. Secondary outcome was quality of life. Risk of bias and quality of study reporting were also assessed. The search found 3872 articles, with 5 articles meeting the PICO (population, intervention, comparison, outcomes) criteria, 4 pre-post studies, and one observational cohort study. The total sample included 2763 patients. Follow-up was variable. The follow-up varies from 7.8 to 120 months, with an average of 35 months. Lymphedema reduction was obtained in the five studies. Conclusion: The present systematic review suggests that for patients with lymphedema secondary to breast cancer, the combination of both treatments is effective in reducing the size of the limb and improving quality of life. Low-quality evidence was found for both limb circumference reduction and quality of life. Additional research effort is needed to reduce bias and improve the quality of evidence, in order to better inform clinical practice and enhance the care and well-being of patients with BCRL.

Background: Manual lymphatic drainage (MLD), one of the components of complex decongestive physiotherapy, which is accepted as the gold standard in the treatment of lymphedema, is used for therapeutic purposes in many diseases. The most well-known feature of MLD is that it helps to reduce edema. In addition to reducing edema, MLD has many effects, such as increasing venous flow, reducing fatigue, and raising the pain threshold. To the best of our knowledge, there is no study examining the effects of MLD other than its effects on edema in detail. The aim of this study is to compile effects of MLD and to provide a better understanding of the effects of MLD. Methods and Results: A literature search was conducted in Medline, Embase, and the Cochrane Library in July 2019, to identify different effects of MLD. The articles were chosen by, first, reading the abstract and subsequently data were analyzed by reading the entire text through full-text resources. To undertake the study, we have collected information published about different effects of MLD over the last 30 years (1989-2019). According to our results, 20 studies met inclusion criteria. Conclusions: This study suggests that MLD can be used in symptomatic treatment of various diseases (multiple sclerosis, Parkinson's disease) considering the effects of MLD on the systems.

Background: The purpose of this study was to investigate acute cardiovascular responses to manual lymphatic drainage (MLD) on different parts of the body. Materials and Methods: Thirty healthy individuals (10 women and 20 men) participated in the study voluntarily. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), respiration frequency, and oxygen saturation were measured before and after MLD was applied to different regions of the body (neck, abdomen, anastomosis, arm, and leg). HR, SBP, and DBP were measured with a sphygmomanometer (OMRON, USA) and oxygen saturation was measured with a pulse oximeter. Results: Increase in DBP was seen after abdominal drainage ( p  = 0.038); reduction in SBP ( p  = 0.002) and DBP ( p  = 0.004) after neck drainage; reduction in SBP ( p  < 0.001) and HR ( p  = 0.004) after arm drainage; and reduction in SBP and DBP after leg drainage. There was no change in the oxygen saturation levels of participants after MLD ( p  > 0.05). Conclusions : In healthy subjects, the effects of MLD were found to vary according to the region of application. This study signals that the cardiovascular effects of MLD treatment vary in different regions of the body.

Background: The aim of this prospective clinical study was to compare the long-term efficacy of complex decongestive therapy (CDT) in obese and nonobese patients with breast cancer-related lymphedema (BCRL)., Materials and Methods: A total of 59 patients (29 obese patients group 1, 30 normoweight overweight patients group 2) with unilateral BCRL were enrolled. All patients underwent CDT that included manual lymphatic drainage, intermittent pneumatic compression pump, multilayer compression bandaging, lymphedema exercises, and skin care. The CDT was performed for 1 hour a day, 5 days a week for 3 weeks. Patients were assessed according to limb volume difference before CDT, after CDT, and after 1 year., Results: The initial lymphedema volume of group 1 was 866.34 ± 389.34 mL and that of group 2 was 661.84 ± 470.6 mL (p = 0.031). The lymphedema severity percentage of excess volume (PEV) of group 1 was 33.37 ± 15.71 and that of group 2 was 31.86 ± 19.63, which was moderate lymphedema. After 15 sessions of CDT program, in group 1, lymphedema volume decreased to 771.46 ± 389.14 mL (post-CDT p = 0.013) and in group 2, lymphedema volume decreased to 468.38 ± 417.36 mL (post-CDT p < 0.0001), and in group 1, PEV decreased to 28.54 ± 16.84 (post-CDT p = 0.002) and that in group 2 decreased to 22.1 ± 16.87 (post-CDT p < 0.0001). After 1 year, group 1 reached the baseline values of the extremity volumes, but in group 2, the volumes of extremities could maintain their post-CDT values., Conclusion: Obesity is a factor that deteriorates the CDT efficacy. Early treatment, before developing fat accumulation and fibrosis, must be primary goal in the treatment of BCRL.

Background: Multilayer bandaging used in complex decongestive therapy (CDT) may increase tissue pressure resulting in nerve entrapments. The aim of this study was to discover if median nerve damage is a consequence of CDT in patients with breast cancer-related lymphedema (BCRL)., Methods and Results: Eighty-two arms of 41 patients with BCRL were included. Mean age was 56.05 (8.16) years and all stages of lymphedema were equally included. Fifteen sessions of CDT was applied to all patients. The calculated volume of extremities, the quality of life (cancer adaptation of Ferrans-Powell), neuropathic pain (NP; Douleur Neuropathique 4), and disability (quick disabilities of arm, shoulder, and hand [Q-DASH]) tests were recorded before and after therapy. Skin and subcutaneous tissue thicknesses of volar and dorsal sides and median nerve cross-sectional area (CSA) at the level of carpal tunnel were measured using ultrasonography (US), before and after therapy. Carpal tunnel syndrome (CTS; 41.37%) and polyneuropathy (10.34%) were common findings confirmed by electromyography. Neuropathic pain profile was also found in 34.14% of patients. The arm volume of affected side, quality of life, and skin and subcutaneous tissue thicknesses were improved after therapy (p < 0.05). However, median nerve CSA, the NP, and Q-DASH scores were not changed after therapy., Conclusions: Although lymphedema is a painless condition, NP and CTS should not be ignored in patients with BCRL. US is an alternative, precise, and high technological method for evaluating treatment response. CDT is an effective and safe treatment according to volumetric calculations, US measurements of tissue thicknesses, and median nerve size.

Background: Lymphedema is a chronic peripheral swelling caused by a dysfunction of the lymphatic system, leading to discomfort and loss of upper limb movement. Therapies to treat or manage this swelling have limited evidence, partly because of a paucity in objective lymphatic measures. This study explored the role of near-infrared (NIR) imaging in evaluating interventions., Methods: Nine healthy volunteers underwent NIR fluoroscopy using a microdose (50 μL, 0.05% w/v) of indocyanine green to quantify lymphatic behavior before and after a 15-minute period of manual lymph drainage followed by compression garment (CG) therapy for a 10-minute period. Images were taken at the forearm and elbow after each intervention. Lymphatic function was defined by the number, size, displacement, and speed of lymph packets. The lymph parameters were analyzed to assess the effects of the interventions compared with basal values., Results: Baseline (BL) parameters of lymph function revealed high variability in the number, size, and speed of packets between individuals. Despite this variance, both interventions showed statistically significant improvement (p < 0.05) in displacement and speed at the forearm compared with BL. The velocity of transient lymph packets increased from a median of 6.7 mm/s at BL to 13.3 mm/s after manual lymphatic drainage (MLD) and 10.5 mm/s after CG., Conclusion: Lymphatic activity increased significantly after MLD, with relative increases being maintained after a short time period of CG application. NIR fluoroscopy has the potential to both monitor lymph pathology and provide robust parameters in the assessment of interventions.
