Filter by:The purpose of the study is to investigate the ability of mass spectrometry imaging to locate aggregates of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) ex-vivo, and to distinguish areas containing these carcinomas from normal skin. It is suggested that non-melanoma skin cancer (NMSC) cells show a different profile of endogenous lipids than healthe skin tissue which can be used as identifying biomarkers. If that hypothesis is correct it will be possible in the future to develop real-time tissue diagnosis and treatment of NMSC using mass spectrometry guided surgery. Method between 60 and 100 patients with BCCs, SCCs, and actinic keratoses (AK) will be recruited. For patients referred for Mohs surgical procedure at the Department of Dermatology, Bispebjerg Hospital, to treat BCCs or SCCs, three skin sections (5-10 um thick) of the tissue that is already removed will be use in our study. One section will be HE stained so we know exactly where the regions of interest are. Two sections will be used for MS analysis (MSI spectrum and REIMS spectrum). When patients are referred for a procedure to have treated several actinic keratoses (grade 1, 2 or 3) at Department of Dermatology, Bispebjerg Hospital we will take an extra punch biopsy (2-4 mm) depending on the size of the lesion. The biopsy is embedded and sectioned. We will use 3 skin sections (5-10 um thick) we will again use one section for HE staining and two for MS analysis. Multivariate statistical analysis will be performed on all mass spectra using Matlab or similar program. Linear discriminant analysis will be used to identify spectral differences between pre-malignant, cancer and normal tissue. Classification performance will be recorded with a leave-one- patient- out cross- validation scheme.
The investigators want to assess the safety and efficacy of using intralesional 5-FU for the management of different types of BCC (including all the types EXCEPT the infiltrative one), by estimating different outcomes after the intralesional administration of 5-FU to BCC patient. Patients are randomly selected from the outpatient dermatologic clinic in the Aleppo University Hospital (AUH) over a period of 12 months and then these patients are followed up over another 12 months.
Reflectance confocal microscopy (RCM) is the reference in vivo imaging technique for identifying malignant melanocytic tumors prior to surgical excision. However, it is not widely used due to its high cost and highly technical and time-consuming nature. In addition to RCM, we currently use 2 less expensive dermatoscopes that also allow in vivo diagnosis: super-high magnification dermoscopy (D400) and Fluorescence-Advanced videodermatoscopy (FAV).
Basal cell carcinoma (BCC) is the most common form of cancer among the Caucasian population. Equivocal BCC lesions are usually diagnosed by means of a punch biopsy, but since the last few decades, non-invasive imaging techniques for the diagnosis of BCC gained popularity within the field of dermatology. Conventional optical coherence tomography (cOCT) is an example of a non-invasive imaging technique. Recent studies revealed that OCT assessors may achieve high diagnostic certainty and accuracy for diagnosing BCC. However, cOCT has a limited axial and lateral resolution and can therefore only visualize the gross architecture of the skin. It has been proposed that the diagnostic certainty and accuracy of cOCT could be optimized by improving the resolution. Line-field confocal optical coherence tomography (LC-OCT) is a new non-invasive imaging technique that provides tridimensional images of the skin with a cellular resolution. Although the resolution of LC-OCT is superior to cOCT, the penetration depth of LC-OCT (500µm) is limited compared to that of cOCT (1.0-1.5mm). In the proposed study, we aim to assess whether LC-OCT is superior to cOCT in terms of diagnostic accuracy for diagnosing BCC in equivocal BCC lesions.
Mohs micro-graphic surgery (Mohs) is a tissue-sparing, surgical treatment for different types of skin cancer (e.g. basal cell carcinoma, squamous cell carcinoma, lentigo maligna (melanoma). It is a procedure performed with frozen sections. Slow Mohs, a variant of micro-graphic surgery, is performed by formalin fixation and paraffin-embedded sections. Both in Mohs and Slow Mohs tumor margins are assessed to achieve complete removal. This study aims to investigate the clinical presentation and outcomes (i.e. complications and recurrence rates) in patients treated with Mohs or Slow Mohs in the dermatology department of the Maastricht University Medical Center+ in Maastricht, the Netherlands.
The overall aim of the project is to gain knowledge about the expected course of nevoid basal cell carcinomas and the usefulness of dermatoscopy in young individuals with Gorlin syndrome. Clinical experience and some case-reports suggest that nevoid basal cell carcinomas have an indolent course with slow growth and that they can sometimes regress. However, no systematic research has previously been performed. Increased knowledge about nevoid basal cell carcinomas and the use of dermatoscopy could be of great clinical value in the follow-up and treatment of individuals with nevoid basal cell carcinoma syndrome.
Participants of this study will have a diagnosis of a solid tumor cancer that has come back to its original location or spread beyond its original location (advanced), came back (relapsed) or worsened (refractory) after standard treatments, or no standard treatments are available for the participants' cancer. The purpose of this study if to find the highest dose of MQ710 that causes few or mild side effects in participants with a solid tumor cancer diagnosis.
To readdress basal cell carcinoma (BCC) in the periocular region to prove histologically controlled surgical treatment efficacy and to identify high-risk characteristics.
Basal cell carcinoma (BCC) is the most common form of cancer among the Caucasian population. A BCC diagnosis is commonly establish by means of an invasive punch biopsy (golden standard). Optical coherence tomography (OCT) is a safe non-invasive diagnostic modality which may replace biopsy if an OCT assessor is able to establish a high confidence BCC diagnosis. Hence, for clinical implementation of OCT, diagnostic certainty should be as high as possible. Artificial intelligence in the form of a clinical decision support system (CDSS) may improve the diagnostic certainty of newly trained OCT assessors by highlighting suspicious areas on OCT scans and by providing diagnostic suggestions (classification). This study will evaluate the effect of a CDSS on the diagnostic certainty and accuracy of OCT assessors.
The goal of this clinical trial is to compare the use of two photon fluorescence microscopy for detecting residual basal cell carcinoma during Mohs surgery. The main question it aims to answer is: • How similar are diagnosis of surgical margins to on two photon fluorescence microscopy compared to frozen section histology
