Filter by:The purpose of this study is to find out whether the Nevisense device can provide useful information about atypical moles to complement the usual assessments done during routine screening for melanoma. Assessing particpants' moles with the Nevisense device may help improve screening methods for the early detection of melanoma in people with atypical mole syndrome.
Aim of study: To collect data for a new image-guided diagnostic algoritm, enabling the investigators to differentiate more precisely between benign and malignant pigmented tumours at the bedside. This study will include 60 patients with four different pigmented tumours: seborrheic keratosis (n=15), dermal nevi (n=15), pigmented basal cell carcinomas (n=15), and malignant melanomas (n=15), these four types of tumours are depicted in Fig.1, and all lesions will be scanned by four imaging technologies, recruiting patients from Sept 2019 to May 2020. In vivo reflectance confocal microscopy (CM) will be used to diagnose pigmented tumours at a cellular level and provide micromorphological information5;6. Flourescent CM will be applied to enhance contrast in surrounding tissue/tumours. Optical coherence tomography (OCT), doppler high-frequency ultrasound (HIFU) and photoacustic imaging (also termed MSOT, multispectral optoacustic tomography) will be used to measure tumour thickness, to delineate tumours and analyze blood flow in blood vessels. Potential diagnostic features from each lesion type will be tested. Diagnostic accuracy will be statistically evaluated by comparison to gold standard histopathology
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.
The BAP1 trial will examine the blood of patients diagnosed with choroidal nevi or uveal melanoma for a germline BAP1 mutation and other genetic markers associated with developing malignancy as well as additional sequencing of the uveal melanoma genome.
Malignant Melanoma is a deadly skin cancer that can be cured if diagnosed early. To date atypical pigmented skin lesions are diagnosed by appearance alone and many moles and lesions are excised unnecessarily and on the other hand malignant lesions are missed and diagnosed too late. In this study a protein conjugated to a florescent dye is spread on a suspicious pigmented lesion, the hypothesis is that this protein binds to malignant cells only and thus with a special camera that picks up the dye we can find pigmented lesions with early malignant transformation.
This trial will investigate whether four doses of RN1001 (20ng, 50ng, 100ng and 200ng) are efficacious in preventing or reducing the resultant scar, as compared to placebo, when applied intradermally to wound margins following excision of benign naevi situated on the head and neck.
