Active clinical trials for "Nevus"

The investigators are doing this study to improve our ability to identify which people with many moles on their skin are most likely to develop skin melanoma. The investigators hope to identify features of moles that are associated with melanoma risk. The investigators hope to use this information to customize and tailor melanoma screening to the individual patient based on a better estimate of their individual risk.

This is a pilot study to see if oral administration of freeze dried, powdered broccoli sprouts have any effect on whether moles end up becoming melanoma.

The purpose of this study is to evaluate the safety and effectiveness of an experimental 20% betulinic acid ointment (BA ointment) as a treatment for dysplastic nevi with the potential to transform into melanoma.

This is a single-arm, phase II study to assess the efficacy of combined SMO and PD-1 inhibition with Vismodegib (SMO inhibitor) and Nivolumab (anti-PD-1 antibody) in BCNS patients (target enrollment of 22 patients), with a primary endpoint of 18-month disease control rate. The purpose of this study is to test the hypothesis that Nivolumab and Vismodegib will improve the percentage of BCNS patients who achieve disease control (defined as total tumor burden <50% of baseline) at 18 months from 50% to 80%. Baseline and on-treatment biopsies will be obtained to characterize the immune effects of combined SMO and PD-1 inhibition.

This research study is designed to better understand the role of genetics, sun-exposure and phenotypic factors in melanoma.

The "Nevus doctor" is a dermatoscopy based computer decision support tool to assist general practitioners (GPs) in the classification of pigmented skin lesions (PSLs). The aim of the program "Nevus doctor" is to help GPs increase their diagnostic accuracy, in particular regarding the selection of suspicious PSLs that need biopsy or referral to specialist health care for further assessment. The aim of this study is to investigate the diagnostic performance of the decision support tool in a primary care setting in Norway. We hypothesize that the diagnostic accuracy of the computer program "Nevus doctor" is better than the performance of the GPs.

Choroidal nevomelanocytic lesions have a high prevalence affecting up to 7% of the entire population and are increasingly incidentally identified during routine eye check- ups in community optometry services. Given the tendency to err on the side of caution, there is evidence of excessive referrals challenging service delivery in both tertiary eye units and specialist ocular oncology services. Although previous studies have examined the natural history and risk factors for growth of choroidal nevomelanocytic lesions, optimal delivery of management remains uncertain. Management approaches display diversity with respect to the number and type of baseline investigations, the duration and frequency of monitoring of relevant patients. Utilisation of the skills of allied health professionals in appropriate cases would allow streamlining service delivery in a socialised healthcare system, maximise capacity, and allow community services to play an enhanced role. However, the evidence for this model of delivery is lacking. Within existing models of care for these lesions, patients are faced with delays, need for more than one attendances to the hospital and increased anxiety around prognosis. This project aims to answer the question of whether these low-risk, bland incidental findings might possibly be managed by allied health professionals with the use of clinical imaging and specific algorithms to make appropriate management decisions. We aim to validate a model of service delivery on a virtual basis that will accommodate for capacity pressures to accept all relevant referrals, while offering a safe service and optimising patient experience of care. We will thus validate the setting up of a virtual choroidal nevomelanocytic clinic in terms of safety and patient acceptability. More specifically, the degree of agreement between management decisions made by non-medical graders on the basis of imaging data alone as opposed to gold standard decisions (clinical and imaging tests combined) is examined. Health economics analysis of the proposed service delivery model will be undertaken to demonstrate cost-effectiveness.

This study is to analyze whether more changes in melanocytic nevi (MN) occur in women during and after pregnancy compared to non-pregnant women of the same age and to analyze psychological effects of total body mapping and dermoscopic examination assisted by artificial intelligence during pregnancy.

This project is a multicenter study in which we will investigate a dual concept of nevogenesis. Study location is the Department of Dermatology at the Medical University of Graz in collaboration with centers in Austria (Vienna), Italy (Naples, Benevento, Modena), Spain (Barcelona) and the United States (New York). The hypothesis is that small congenital melanocytic nevi (CMN), "early" acquired melanocytic nevi in childhood (AMN) and dermal nevi, all dermatoscopically characterized by globular pattern, belong to the same spectrum of genetically determined melanocytic proliferations that develop due to endogenous pathways, in contrast to "true" acquired melanocytic nevi, dermatoscopically showing reticular pattern, that develop due to exogeneous factors such as UV-exposure.

The purpose of this study is to determine if the investigators can detect the presence of choroidal nevi cells in the vitreous fluid of humans, as this may improve the diagnosis and classification of choroidal nevi and melanomas in the future.
