Filter by:In the last 10 years, the treatment of metastatic cutaneous melanoma has changed dramatically. The new systemic treatment with immunotherapy has led to a dramatic improvement in quality of life and overall survival. Systemic treatment means that the patient receives the drug as an infusion into a vein. Unfortunately, we know that immunotherapy is not equally successful in all patients. Recent studies have shown that the success of the treatment is not only influenced by the cellular composition of the metastasis, but also by its surroundings. This is called tumor microenvironment. Depending on the differences in the composition of this microenvironment, some metastases can be described as immunologically hot and others as immunologically cold. Immunologically hot metastases respond better to immunotherapy than immunologically cold metastases. Studies have shown that with some interventions we can change the tumor microenvironment from being immune-cold to being immune-hot. Electrochemotherapy is one of the interventions that might improve the efficacy of immunotherapy in cutaneous melanoma. Electrochemotherapy is an established method for the local treatment of tumors, in which only a certain tumor is treated with special electrodes, to which a weak electric current is applied. We hypothesize that electrochemotherapy stimulates the body's own immune response and enables more effective treatment. Since immunotherapy also stimulates the body's own immune response to cutaneous melanoma cells, the interaction of the two drugs could be even more successful. Recent research results support this assumption. The primary objective is to evaluate the changes in the tumor microenvironment of cutaneous and subcutaneous melanoma metastases induced by electrochemotherapy, based on the histologic analysis of treated and untreated metastases before and after treatment. The secondary aim is to determine whether the changes in the tumor microenvironment differ depending on the chemotherapeutic agent used. The results will help us to better understand the synergistic effects of electrochemotherapy and immunotherapy on cutaneous melanoma metastases. The combination of systemic immunotherapy and electrochemotherapy could become an important treatment method for patients with metastatic melanoma.
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.
The goal of this study is to estimate the triage values, efficiency and safety of tele-dermoscopic triage of skin lesions suspected of melanoma. The main question[s] it aims to answer are: - What is the rate of correct patient management by a single, 2, 3 and 5 dermatologists. - What is the consequence for the patients if teledermoscopic triage is implemented, in termes of missed melanomas and reduced unnecessary excisions/biopsies. Retrospectively included patients will have their skin lesions re-examined by setups of 1, 2, 3 and 5 tele-dermoscopists who will assign a tentative diagnosis and a recommended clinical action. The investigators will compare the rate of correct patient management between the different setups.
The goal of this clinical trial is provide new treatment for patients with advanced melanoma who have failed previous immunotherapy. The main questions it aims to answer are: - Efficacy of PD1 monoclonal antibody combined with recombinant human adenovirus type 5 injection in patients with advanced malignant melanoma. - Safety of PD1 monoclonal antibody combined with recombinant human adenovirus type 5 injection in patients with advanced malignant melanoma.
The goal of this clinical trial is to investigate a new approach for treating large uveal melanomas, a type of eye cancer. The study aims to determine the effectiveness of using intra-arterial melphalan, a chemotherapy drug, to reduce tumor thickness, allowing for subsequent radiation therapy using a Ru-106 plaque. The main questions this trial seeks to answer are: - Can intra-arterial melphalan effectively reduce the thickness of large uveal melanomas? - Is the combination of intra-arterial melphalan and brachytherapy a safe and effective treatment option for these tumors? Participants enrolled in the trial have clinically diagnosed choroidal melanoma with tumor thickness equal to or greater than 8.00 mm. They will undergo a procedure where the chemotherapy drug is injected directly into the blood vessels that supply the tumor. After a few weeks, they will receive the radiation treatment using a small device placed on the eye. Throughout the trial, participants will have different tests to monitor the tumor and their vision, such as ultrasound scans, pictures of the inside of the eye, and a test called electroretinography (ERG) to check the function of the retina. These tests will be done at the start of the trial and at 1, 3, and 6 months later to track the progress of the treatment.
It has been suggested that pathologists' diagnostic accuracy and confidence could be improved if they gained access to additional clinical information and in-vivo clinical and dermoscopic images of melanocytic tumors. This study examines the effect of digital training for pathologists in interpreting dermoscopic and clinical skin tumor images. The primary outcome of the upcoming DAHT RCT (Dermoscopy Augmented Histology Trial, a randomized controlled trial) is the diagnostic value (accuracy, sensitivity, and specificity) for the intervention and control group. For this purpose, we need an irrefutable gold standard diagnosis for all DAHT cases. The DAHT consensus trial strives to establish this gold standard through a four-phased Delphi-like process. Aim: To establish a gold-standard diagnosis for all DAHT cases. Data collection of DAHT cases: Department of plastic surgery, Herlev hospital, year 2020-2021 DAHT platform: Made in 2021-2023 by Melatech Consensus agreement: Four dermatopathologists assess all DAHT cases, year 2023
Background: Many advances have been made in cancer treatments, but more research is needed. Comparing samples of cancerous tissue to samples of normal, noncancerous tissues may help find differences between them. These differences may help researchers find new ways to treat cancer. Objective: To collect tissues and blood samples from people with known or suspected cancer. The samples will be used to help identify new targets for cancer treatments. Eligibility: People aged 18 years and older with a known or suspected cancer that requires surgery or biopsy. Design: Participants will be screened. They will answer questions about their health. They can do this on the phone or in person. Researchers will collect information from participants medical records. Data may include information about any prior or current cancers. Data about other medical conditions may also be collected. Participants will have blood drawn. Some of the blood will be tested for HIV and hepatitis B and C. Some of the blood will be used for genetic research. Participants will have tissue samples collected during surgeries or biopsies. These are procedures the participants would have had as part of their standard care. No new procedures will be done just for this study. Researchers may also seek out samples from prior procedures the participant had done. Participants will remain in the study for 6 months. They may have blood drawn again. Researchers may also collect tissue samples from any procedures performed during that time.
Study of Zirconium Zr 89 Crefmirlimab Berdoxa PET/CT as an imaging biomarker for assessing an early response to therapy in patients with advanced melanoma on immunotherapy and hydroxychloroquine. This study is a companion study to the "LIMIT Melanoma Trial." Patients with melanoma who are potentially eligible for the LIMIT Melanoma Trial and have at least one site of measurable disease based on RECIST 1.1 are potentially eligible. Associations with progression-free survival (PFS) and overall survival (OS) will be tested.
This Pilot Study is to investigate the tear proteins in a multitude of cancer types and indulge in biomarker discovery to manufacture simple, accurate, and novel tear-based diagnostic tests.
This is a scientific study to determine expression of vascular adhesion protein 1 (VAP-1) in cancer patients by 68Ga-DOTA-Siglec-9 positron emission tomography/computed tomography (PET/CT) before and after cancer treatment.
