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.
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.
A double-blind, randomized, placebo controlled intervention trial on patients with actinic keratosis.
Rationale: To date, the diagnosis and subtyping of basal cell carcinoma (BCC) is verified with histopathology which requires a biopsy. Because this technique is invasive, new non-invasive strategies have been developed, including Optical Coherence Tomography (OCT). This innovative technique enables microscopically detailed examination of lesions, which is useful for diagnosing and identification of various subtypes of BCC. The diagnostic value of the VIVOSIGHT OCT in daily clinical practice, has not been established to date.
Part I is designed as a study of P-MNA application in healthy human volunteers. The goal of Part I is to determine several factors possibly affecting the rate and extent of microneedle array dissolution, such as anatomic location; age; duration of array exposure to the skin; and the criticality of proper array application to the skin. Part II will be a randomized study in which doxorubicin-containing arrays will be applied to subjects demonstrated by biopsy to have basal cell cancer. A subject will be randomized to one of four dose groups: placebo microneedle array and 50 µg, 100 µg, and 200 µg doses of doxorubicin in a tip-loaded, dissolvable microneedle arrays (D-MNA).
The purpose of this study is to find out whether injecting ALA into the skin with a jet-injection device and activating the drug with light is a safe treatment that causes few or mild side effects in people with basal cell carcinoma.
Collect real world safety data on the use of sonidegib in adult patients with laBCC. Document major safety parameters such as on treatment deaths, adverse events (AEs)/ serious adverse events (SAEs) and discontinuation secondary to AEs.
The investigator believes that injecting Copaxone into tumors will help participants immune system fight cancer. This has been studied in mice and has shown encouraging results. Copaxone is a safe medication currently used to treat Multiple Sclerosis (MS) and has very few side effects. To be considered for this trial a tumor must be easy to be injected and must be at least the size of a pea. Participants will be closely monitored for any side effects. Tissue from before surgery will be compared to tissue after the treatment and surgery to be checked for immune response and anti-tumor effects.
A multi-centre randomized non-inferiority trial investigating the (cost-)effectiveness of Optical Coherence Tomography (OCT) versus regular punch biopsy in the diagnosis and subtyping of Basal Cell Carcinoma (BCC).
