Lymphatic Research and Biology

Background: Lipedema is a disease characterized by an increase in extracellular fluid. In these patients, the increase in the amount of extracellular fluid may accelerate the progression of the disease. The aim of this study is to examine the effect of complex decongestive therapy (CDT) on intracellular/extracellular fluid balance. Methods and Results: Twenty-two female patients diagnosed with lipedema by a specialist lymphologist were included in the study. Patients were subjected to complex decongestive therapy and pneumatic compression therapy 6 days a week for 1 month...

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)...

Background: Lymphedema in the lower abdomen and genitals is unnoticeable and has no established diagnostic methods. In this study, we evaluated it using four examinations. Methods: We evaluated 25 patients with lymphedema in the legs, dividing the abdomen and genitals in four areas (right and left, upper and lower). The mean age was 58.6 years. In lymphoscintigraphy and indocyanine green (ICG) lymphography, we diagnosed lymphedema when dermal backflow was observed. ICG lymphography was performed in 13 patients...

Introduction: Among super-microsurgical techniques, the anastomosis of vessels smaller than 0.5 mm is very difficult to perform due to the small diameter and thinness of the blood and lymphatic vessel walls. In this article, we report on the main points of super microsurgery, particularly on the anastomosis of veins and lymphatic vessels with diameters smaller than 0.5 mm. Methods and Results: Details of anastomosis of vessels smaller than 0.5 mm. (1) The outer wall of the first blood vessel near the abrupt end hook with the tip of the needle in the needle holder...

Background: Breast cancer-related lymphedema (BCRL) is a disabling and frequently occurring condition after treatment for breast cancer. Studying lymph anatomy by means of indocyanine green (ICG) lymphography is a promising tool to help better understand BCRL. The aim of this study is to investigate the relation between ICG lymphography characteristics and the risk of developing BCRL. Methods and Results: Patients scheduled for breast surgery with either unilateral axillary lymph node dissection or sentinel lymph node biopsy between November 2017 and May 2019 were included...

Background: Complex decongestive therapy (CDT) is being used in breast cancer-related lymphedema (BCRL). The degree of initial edema and bioimpedance analysis (BIA) are known to be related with the therapeutic effect of CDT. D-dimer can indirectly reflect lymphangiogenesis because IL-6 regulates D-dimer and vascular endothelial growth factor, which is the most important lymphangiogenic factor. We assessed whether D-dimer could be used for the prediction of therapeutic effect of CDT, as well as BIA and initial edema...

Background: Lymphedema is a common complication after mastectomy in women with breast cancer. Several methods have been described to assess and diagnose lymphedema, one of the most studied being the perimeter and ultrasonography. However, the reliability of these methods and the correlation between them are still controversial. The aim of this study was to analyze the reliability of cytometry and ultrasound imaging in the assessment of lymphedema after mastectomy in women with breast cancer and to study the correlation between them...

Background: Lymphedema is chronic limb swelling resulting from lymphatic dysfunction. It affects an estimated five million Americans. There is no cure for this disease. Assessing lymphatic growth is essential in developing novel therapeutics. Intravital microscopy (IVM) is a powerful imaging tool for investigating various biological processes in live animals. Tissue nanotransfection technology (TNT) facilitates a direct, transcutaneous nonviral vector gene delivery using a chip with nanochannel poration in a rapid (<100 ms) focused electric field...

Introduction: Evaluation of lymph circulation is significant in lower extremity lymphedema (LEL) management. Single-photon emission computed tomography-computed tomography (SPECT-CT) has been introduced for lymphedema evaluation, but its characteristic findings are yet fully clarified. The purpose of this study was to reveal typical SPECT-CT findings in secondary LEL by contrasting with indocyanine green (ICG) lymphography findings. Methods: This is a single-center retrospective case-control study. Medical charts of cancer survivors who underwent SPECT-CT and ICG lymphography for secondary LEL were reviewed...

Background: Breast cancer survivors (BCSs) have many lifelong symptoms of anxiety, depression, lymphedema, and fatigue that can be exacerbated by sleep disturbance. However, little is known about unique factors contributing to sleep disturbance among BCSs with lymphedema; this requires further investigation to offer appropriate support and treatment to these individuals. Therefore, the objective of this study was to capture perceptions and experiences of lymphedema and sleep among BCSs with lymphedema. Methods and Results: Qualitative description guided data collection and analysis as part of a mixed-methods investigation to characterize sleep disturbance among BCSs with and without lymphedema...

Background: Breast cancer-related lymphedema (BCRL) is the most prevalent comorbidity that occurs following breast cancer treatments and has negative impact on the patients' quality of life (QoL). The Lymphedema Functioning, Disability, and Health Questionnaire for Upper Limb Lymphedema (Lymph-ICF-UL) is a valid and reliable instrument in assessing the QoL of patients with BCRL. However, the Bahasa Malaysia (BM) version is not available yet. This study aimed to translate the Lymph-ICF-UL into BM and to evaluate its validity and reliability...

Background: Indocyanine green (ICG) lymphography, a key diagnostic tool for lymphedema, is influenced by the dilution process of ICG dye, impacting patient experience. Methods and Results: In our study, we assessed three different ICG diluents-water for injection (WFI), normal saline (NS), and Dextrose® plus human albumin-in five healthy volunteer individuals undergoing superficial lymphography of the upper limb over 3 weeks. Results indicated that NS, as a diluent for ICG, caused the least discomfort during injection, in contrast to WFI, which led to the highest levels of discomfort...

Background: We aimed to determine the course of arm swelling caused by the use of taxanes and to identify valid predictors of persistent swelling. Methods and Results: A total of 15 patients with unilateral arm swelling that developed during the course, or within 3 months after termination, of postoperative taxane-based chemotherapy were included in the present study. The patients attended follow-up appointments every 3-6 months for 24 months after their initial visit. Their arm circumference was measured at each follow-up appointment, while ultrasonography of the skin and subcutaneous tissues was performed at the 0-, 6-, 12-, and 24-month follow-ups...

Purpose: Genital lymphedema is a chronic debilitating condition associated with highly impaired health-related quality of life (QoL). This prospective multicenter study evaluated the use of a new compressive garment in patients with secondary and primary genital lymphedema. Methods: Thirty-two patients prospectively enrolled were advised to wear the compressive garment for 12 weeks (day and night). The primary endpoint was change in patient-reported QoL at 12 weeks via the patient global impression of change (PGI-C) instrument...

Background: Recently, the usefulness of lymphatic ultrasound has been reported. It is beneficial not only to identify lymphatic vessels but also to evaluate lymphatic degeneration and diagnose lymphedema. We previously proposed D-CUPS (Doppler, Cross, Uncollapsible, Parallel, and Superficial fascia) to identify the lymphatic vessels on ultrasound. The purpose of this study was to clarify the sensitivity of each index of D-CUPS. Methods: We performed a retrospective study of 27 patients (44 limbs, 98 sites) with lower extremity lymphedema, who underwent lymphaticovenous anastomosis (LVA)...
