BACKGROUND:  Breast cancer-related lymphedema (BCRL) affects many areas of daily living. Individuals with lymphedema may experience chronic and progressive swelling, recurrent skin infections, and decreased self-image and quality of life. For many years, it was considered best practice for this population to avoid exercise; however, in recent years, research has begun to challenge this belief. This systematic review and meta-analyses examined the recent literature on the effects of exercise for patients with, or at risk for, BCRL to inform best practice...

The transcription factor PROX1 is essential for development and cell fate specification. Its function in cancer is context-dependent since PROX1 has been shown to play both oncogenic and tumour suppressive roles. Here, we show that PROX1 suppresses the transcription of MMP14, a metalloprotease involved in angiogenesis and cancer invasion, by binding and suppressing the activity of MMP14 promoter. Prox1 deletion in murine dermal lymphatic vessels in vivo and in human LECs increased MMP14 expression. In a hepatocellular carcinoma cell line expressing high endogenous levels of PROX1, its silencing increased both MMP14 expression and MMP14-dependent invasion in 3D...

Retrograde menstruation is common and in about 10% of women, endometrial tissues implant at ectopic sites and grow as endometriosis (EM) deposits. To date, there has been no marker to identify which patients have an endometrium that will generate deposits. Both endometrial regulatory T cells (Tregs) and increased stromal cell indoleamine 2,3-dioxygenase (IDO) have been implicated, and may suppress rejection by peritoneal NK cells, neutrophils, and cytotoxic macrophages. CD200 is a tolerance signaling molecule which promotes Tregs, IDO-producing macrophages, and can directly inhibit cytolytic natural killer (NK) cells and neutrophils...

INTRODUCTION: Ultrasonography is the easiest non-invasive method to diagnose lymph node metastases in patients with head and neck cancer. However, since CT scans are often preferred in the evaluation of primary tumours of these patients, information about lymphatic metastases may also available in these patients. Therefore, ultrasound is not routinely employed in the evaluation of these patients. However, elastography technique, a recent development in ultrasound technology, could make use of ultrasonography in these patients even more widespread, even though it is still not widely used today...

OBJECTIVE: Tumor necrosis factor receptor-associated factor 6 (TRAF6) is an essential component of the signaling complex that mediates osteoclastogenesis. As an adaptor protein of E3 ligase function, TRAF6 regulates NF-κB signaling via TAK1 and I-κB kinase (IKK) activation. Here, we investigated novel mechanisms by which TRAF6 signaling is regulated under receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclastogenesis. DESIGN: A yeast two-hybrid screen system identified cellular factors that interact with TRAF6...

Lymphatic filariasis, onchocerciasis and loiasis are widespread neglected tropical diseases causing serious public health problems and impacting the socio-economic climate in endemic communities. More than 100 million people currently suffer from filarial infections but disease-related symptoms and infection-induced immune mechanisms are still ambiguous. Although most infected individuals have dominant Th2 and regulatory immune responses leading to a homeostatic regulated state, filarial-induced overt pathology like lymphedema, dermal pathologies or blindness can occur...

Background: Non-ampullary duodenal adenocarcinoma, excluding carcinoma in the ampulla of Vater, is a rare disease. Although several prognostic factors have been reported, they remain controversial due to the rarity of non-ampullary duodenal adenocarcinoma. The aims of this study were to investigate prognostic factors in patients with non-ampullary duodenal adenocarcinoma and to assess chemotherapy in patients with recurrence. Patients and methods: Records of 25 patients who underwent surgical treatment for non-ampullary duodenal adenocarcinoma from 2004 to 2016 were retrospectively reviewed...

Lymphatic leishmaniasis is a rare parasitic disease even in endemic region. It is usually associated with visceral and post-kala-azar dermal leishmaniasis. Leishmaniasis is being increasingly recognized in association with immunodeficient patients (HIV/AIDS). However, leishmanial lymphadenitis has been rarely diagnosed by fine-needle aspiration cytology (FNAC) of epitrochlear lymph node in an HIV patient. Cytological features of leishmanial lymphadenitis in an HIV-reactive patient have been rarely addressed in previous literature...

Parkes-Weber syndrome is a congenital vascular disease that comprises capillary, venous, lymphatic, and arteriovenous malformations. Although Parkes-Weber syndrome is a clinically distinct entity with serious complications, it is still frequently misdiagnosed as Klippel-Trenaunay syndrome, which consists of a triad of malformations involving the capillary, venous, and lymphatic vessels, without arteriovenous fistulas. Both syndromes are generally diagnosed with Doppler ultrasound and confirmed by magnetic resonance angiography...

Inflammatory breast cancer (IBC) is a rare subtype of breast cancer, accounting for 8-10% of breast cancer-associated deaths in the US. Clinical hallmarks of IBC include tumor emboli in lymphatic vessels and E-cadherin overexpression, which supports a type of metastasis referred to as cell cluster-based metastasis, prevalent in IBC. In contrast, we previously reported epithelial-to-mesenchymal transition (EMT)-based progression of IBC, utilizing in vivo xenografts and in vitro Matrigel culture models. To address these two contradictory concepts of IBC metastasis, we used Matrigel culture to induce EMT in a panel of IBC cells...

BACKGROUND: The advent of less radical surgical approaches has generated concern about leaving locoregional lymph node metastases (LNM) unresected that could lead to adverse outcome. We examined the prognostic role of clinicopathological factors for ypN-positivity in patients with ypT0-2 rectal carcinoma treated within the CAO/ARO/AIO-94 and CAO/ARO/AIO-04 randomized phase 3 trials. METHODS: The correlation of clinicopathological factors with ypN-status (ypN0 vs ypN1/2) was examined in n = 776 patients with ypT0-2 rectal carcinoma after preoperative CRT and total mesorectal excision surgery using Pearson's Chi-squared test for categorical variables and Kruskal-Wallis' test for continuous variables...

The aim of the present study is to investigate the role of microRNA (miRNA/miR)-409-3p in the proliferation, invasion and migration of tongue squamous cell carcinoma (TSCC) cells via targeting radixin ( RDX ) gene. The expression of miR-409-3p was detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) in TSCC tissue and cell lines. The binding of miR-409-3p to RDX was investigated by performing a dual-luciferase reporter gene assay. Tca8113 cells were selected to transfect with miR-409-3p mimic/inhibitor, small interfering (si)-RDX, and miR-409-3p inhibitor + si-RDX, as well as negative control (NC) respectively...

Background: Intralesional bleomycin scelro-therapy has become a favored line of treatment for macrocystic lymphatic malformations. However the need for multiple sessions is a drawback associated with this treatment modality. Our aim is to document whether multiple session of intra- lesional sclero-therapy is necessary for complete resolution of cystic lymphatic malformation. Method: Intralesional bleomycin under Ultrasound guidance was used for macrocystic lymphangioma at concentration of 3mg/ml but not exceeding the total dose (1mg/kg) body weight for single session or cumulative dose of 5mg/kg...

PURPOSE OF REVIEW: Lymphangioleiomyomatosis (LAM) is a rare systemic disease that occurs almost exclusively in women. In the last few years, our understanding of disease pathobiology has improved substantially; in addition, a guideline document has recently been developed that provides recommendations for the diagnosis and clinical management of patients with LAM. Yet, significant gaps in knowledge remain. RECENT FINDINGS: Groundbreaking insights into the cellular biochemistry of LAM have led to the reclassification of the disease as a low-grade, destructive, metastasizing neoplasm...
