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 purpose of this study is to compare surgical site infection rates for patients treated with Mohs micrographic surgery after bilateral nasal swab with povidone iodine versus standard treatment including the use of a standardized oral antibiotic prophylaxis protocol.
This is a Phase 1, multicenter, open-label dose escalation study to determine the safety and tolerability of intratumoral (IT) injection of ANK-101 in participants with advanced solid tumors.
This study aims to improve patient comfort by exploring the potential of lavender aromatherapy in reducing anxiety and unpleasant odor perception during Mohs Micrographic Surgery (MMS). Lavender has been widely studied for its sedative-like properties and calming effects, both in medical and dental settings. By investigating the impact of lavender aromatherapy on patient anxiety levels during MMS, we seek to provide evidence-based insights into non- pharmacological interventions that can enhance the overall comfort and experience of participants.
Implementing this protocol has its ethical justification in that patients with metastatic melanoma, once tumor invasion has reached beyond the lymph node barrier, cannot possibly be treated satisfactorily with traditional surgery methods, radiotherapy, or conventional available chemotherapy. The disseminated tumor is refractory to all standard treatments. Almost 100% of patients who develop distant metastases will die from their disease, either from complications or cachexia. Therefore, immunotherapy based on immunological stimulation with immunocompetent dendritic cells, added to immunological reinforcement with IL-2, can, according to the evidence emanating from ongoing clinical protocols, produce a prolongation of survival with better quality and, in some cases, with partial or total regression of the tumor. General objective: It is to study the clinical and immunological response of patients treated with vaccines based on autologous dendritic cells loaded with tumor antigens, derived from allogeneic melanoma extracts, in combination or not, with intercalated low doses of recombinant human interleukin 2 (rhIL2) PROLEUKIN ® (aldesleukin). MAIN SPECIFIC OBJECTIVE: - SAFETY: Safety in administering dendritic cell preparation; local and systemic toxicity estimation. Determination of adverse reactions such as fever, nausea, allergy, neurological and cardiovascular symptoms. Local toxicity in the administration area. - MEASUREMENT OF THE IMMUNE RESPONSE: Based on in vivo and in vitro parameters: - In vivo response: Measure the type IV Delayed Hypersensitivity (DTH) response. It consists of a crossover test in which the response is compared to tissue interaction in vivo between dendritic cells sensitized with tumor extracts and their respective control unloaded dendritic cells. - In vitro response: ELISPOT assays, measurement of IFN-γ gamma production in peripheral blood of treated patients. Compare the specific immune response after each cycle of therapy through measurement of IFN-γ production by tumor-specific CTL. Cytotoxic radioactive chromium release assays to measure anti-tumor response mediated by CTL and NK. ELISA assays for quantifying cytokines (IFN-γ, IL-10) in patient serum after each cycle of therapy.
This phase II trial tests how well lifileucel, with reduce dose fludarabine and cyclophosphamide for lymphodepletion and interleukin-2, work for treating patients with melanoma that cannot be removed by surgery (unresectable) or that has spread from where it first started (primary site) to other places in the body (metastatic).Lifileucel is made up of specialized immune cells called lymphocytes or T cells that are taken from a patient's tumor, grown in a manufacturing facility and infused back into the preconditioned patient to attack the tumor. Giving Lifileucel with a reduced dose of fludarabine and cyclophosphamide for lymphodepletion and interleukin -2 is being studied in patients with unresectable or metastatic melanoma.
The proposed project is a pilot study about the impact of different health literacy interventions, focused on preventing skin cancer, on the adhesion to protection strategies against ultraviolet (UV) radiation, observed in high school students, that will be implemented on Foz do Lizandro beach in the municipality of Mafra, Portugal. As a science project with citizenship and respecting the ethic principles of equity, inclusion and diversity, the study will involve the contribution and participation of institutional and community partners in diverse stages of the research study: design, field implementation, data collection and dissemination of results, as well as financial investment for the acquisition and installation of interventions on the beach, and recruitment of the target population.
In this study an artificial intelligence (AI) tool for skin cancer diagnosis is implemented in a teleldermatoscopy platform. The aim is to study the effects on clinician diagnostic accuracy, management decisions, and confidence. Furthermore, this prospective randomized study investigates the role of human factors in determining clinician reliance on AI tools and the consequent accuracy in a real-world setting.
This study explores the role of T cells in monitoring disease status and response during anti-PD-1/PD-L1 treatment in patients with melanoma, lung and other cancer types. Measuring levels of specific targets such as Bim and soluble PD-L1 during therapy may help track treatment resistance and clinical outcomes. This information may also help researchers determine why some people with melanoma, lung and other cancer types respond to PD-1/PD-L1 treatment and others do not.
This is a prospective study to assess efficacy of the Nevisense device in identifying keratinocyte skin cancer (KC) in patients suspected of having skin cancer based on the initial physician's assessment. All skin lesions with a suspicion of Basal cell carcinoma (BCC), Invasive Squamos cell Carcinoma (iSCC), Bowen's disease (BD) or actinic keratosis (AK) and destined for excision or biopsy for further histopathological analysis will be considered for inclusion in the study.
