Active clinical trials for "Lymphadenopathy"

Assess the feasibility of performing a RCT comparing videoendoscopic radical inguinal lymphadenectomy versus open radical inguinal lymphadenectomy in men diagnosed with genital cancer requiring inguinal lymphadenectomy, and determine the design of such an RCT.

This randomized phase II trial studies the safety and how well multi-peptide cytomegalovirus (CMV)-modified vaccinia Ankara (MVA) vaccine works in reducing CMV complications in patients previously infected with CMV and are undergoing a donor hematopoietic cell transplant. CMV is a virus that may reproduce and cause disease and even death in patients with lowered immune systems, such as those undergoing a hematopoietic cell transplant. By placing 3 small pieces of CMV deoxyribonucleic acid (DNA) (the chemical form of genes) into a very safe, weakened virus called MVA, the multi-peptide CMV-MVA vaccine may be able to induce immunity (the ability to recognize and respond to an infection) to CMV. This may help to reduce both CMV complications and reduce the need for antiviral drugs in patients undergoing a donor hematopoietic cell transplant.

The goal of this clinical trial is to evaluate the diagnostic effcacy and safety of transbronchial ultrasound-guided cryobiopsy in the diagnosis of mediastinal lymphadenopathy. The main question it aims to answer are: the effectiveness and safety of transbronchial ultrasound-guided cryobiopsy in the diagnosis of mediastinal lymphadenopathy. Participants will undergo transbronchial ultrasound-guided cryobiopsy (EBUS-TBCB) and endobronchial ultrasound-guided trans-bronchial needle aspiration (EBUS-TBNA).

Endoscopic ultrasound (EUS) and EUS-guided tissue acquisition (EUS-TA) are minimally invasive techniques to establish the benign or malignant nature of lymph nodes (LNs) with a very high accuracy. In particular, for mediastinal LNs, a meta-analysis underlined that EUS features alone are not enough to reach a good sensitivity and specificity, while EUS-TA showed a slightly high sensitivity (88% vs. 85%) and a significantly high specificity (96% vs. 85%) for diagnosing the cause of LN enlargement. Considering all sites, according to the meta-analysis of Xu and colleagues, the assessment of LNs by EUS-elastography is a useful tool in differentiating benign and malignant LNs, with a sensitivity of 88% and a specificity of 85%. For lymphadenopathy of unknown origin, ESGE recommends performing EUS-TA (or alternatively endobronchial ultrasound [EBUS]-guided) if the patient management requires a pathological result and no superficial lymphadenopathy is easily accessible. Unfortunately, EUS-TA may sometimes be challenging or inconclusive, due to blood contamination or insufficient material. EUS elastography (EUS-E) is a non-invasive ultrasound technique that measures the hardness of tissues. The level of hardness of region of interest (ROI) can be evaluated using qualitative scores and/or quantitative methods (strain ratio; SR). To date, most of the studies on EUS-E have been carried out using the Hitachi ultrasound machine. In particular, Paterson performed a quantitative analysis considering as a pathological value cut-off, the SR ≥7.5 for EUS-E in the nodal staging of esophageal cancer. The study involved 53 LNs using cytology as gold standard: their data showed that EUS-E had a sensitivity of 83%, specificity of 96%, PPV of 95% and NPV of 86%. Recently, a new compact ultrasound processor, EU-ME2 (Olympus SE & CO. KG, Hamburg, Germany) that includes an elastography software was developed although data regarding its application in LNs evaluation are still not available. The concept of fractal geometry as a tool for describing natural objects was originally introduced by Benoit Mandelbrot. A fractal can be considered as an irregularly shaped object and that can be divided into fragments, each of them representing a self-similar reduced copy of the whole. The hun body is an example of natural fractal, as many of its parts are characterized by features resembling the typical fractal nature. It has been demonstrated that fractal geometry can be used to efficiently evaluate the geometrical complexity of imaging patterns observed in oncology. The investigators recently published a study on the role of EUS elastography and fractal based analysis in the differentiation of solid pancreatic lesions. However, data regarding the application of fractal analysis to evaluate lymphadenopathies are still not available.

Patients are frequently evaluated by physicians for medical work-up of HIV indicator conditions in hospital and in primary care at the general practitioner. Testing for HIV is indicated with HIV indicator disorder but often omitted in clinical work-up. Besides the fact that HIV testing is forgotten, there are other reasons such as an underestimation of the risk of HIV in the event of indicator disorders, stigma and difficulties in discussing the test with a patient. Also and more relevant for primary care than for the hospital, practical challenges can exist for a patient to go to a laboratory, or costs are a hurdle. This project focuses on improving HIV indicator condition driven testing in different settings of the HIV epidemic, initially in the Netherlands as low HIV prevalence setting followed by an assessment of its benefit in different international settings. A specific focus will also be on the Rotterdam area in the Netherlands which has a high prevalence of undiagnosed HIV in the Netherlands. The ultimate aim is to decrease the number of undiagnosed HIV in populations, improve the 90-90-90 HIV cascade of care goals particularly its first pillar, and to help supporting the UNAIDS goal to end HIV/AIDS

Surgery for vulvar cancer involves removal of the central tumour as well as groin node dissection as indicated depending on the stage of tumour. Groin node dissection is associated with significant complications including lymphorrea, lymphocyst formation, wound breakdown as well as long term complications including lymphedema. This study has been designed with each patient acting as their own control to investigate if using the PlasmaJet during surgery is associated with a reduction in the above mentioned complications.

This trial is aimed to study the efficacy of 4 weekly cycles of rituximab in HIV-infected patients with multicentric Castleman disease (giant lymph node hyperplasia) dependent on chemotherapy. Efficacy is assessed by the complete response rate at day 60. The patients are followed until day 365.

The optimal approach to the drainage of malignant obstruction at the biliary hilum remains uncertain. This is a randomized comparative effectiveness study of percutaneous transhepatic biliary drainage (PTBD) vs. endoscopic retrograde cholangiography (ERC) as the first intervention in patients with cholestasis due to suspected malignant hilar obstruction.

The purpose of this study is to assess if there is decrease in cough during flexible bronchoscopy and endobronchial ultrasound when different modes of lidocaine administration are used. The modes of administration being evaluated are topical, nebulized and atomized.

The main purpose of the present study is to compare the diagnostic yield of different aspiration techniques in Ultrasound-guided Transbronchial Needle Aspiration (EBUS-TBNA) in the diagnosis of hilar/mediastinal adenopathy
