Filter by:This study is open to patients with a type of cancer called melanoma. Patients can join the study if their tumor cannot be removed by surgery or has spread to other organs, and are planned to receive immunotherapy as treatment for their cancer. This study is looking at whether taking calcium pantothenate supplement (a type of Vitamin B5) can increase its levels in the blood and have an effect in the immune system, when its used in combination with the immunotherapy.
The purpose of this study is to determine whether high-intensity exercise and high-fiber diet are feasible and improve various health outcomes among participants with advanced melanoma receiving immunotherapy. The names of the groups in this research study are: - High-Intensity Exercise (EX) - High-fiber Diet (DT) - Combined High-Intensity Exercise and High-Fiber Diet (COMB) - Attention Control (AC)
Melanoma is a serious type of skin cancer and is the 5th most common cancer in the United Kingdom (UK). It can affect anywhere on the skin including on the head and neck. The cancer often is first noticed as an abnormal mole. Treatment is by removing the cancer with surgery. Early spread of the cancer can be found by testing nearby glands called lymph nodes. This operation is called a sentinel lymph node biopsy (SLNB). If the cancer has spread then new treatments, such as immunotherapy, can be given to help the person live for longer. The sentinel lymph nodes are usually in the armpits or groin for melanoma on the body, arms or legs. For cancers in the head and neck the sentinel lymph nodes will usually be in the neck. For several reasons SLNB in the neck is not offered in every hospital that manages patients with melanoma. The problem with this is that some patients who could benefit are not offered the new treatments that extend life because it is not known that their cancer has spread. In this study we aim to gather national data on the management of melanoma of the head and neck including variation in practice between different hospitals. We will use routinely collected anonymous data called 'Hospital Episode Statistics' to look at who is offered SLNB after melanoma of the head or neck, what treatments they have, if their melanoma comes back and how long they survive for. By doing this, we hope to identify whether SLNB should be made available to everyone diagnosed with melanoma of the head and neck.
This study evaluates the effectiveness of applying Hypertonic Saline solution directly on the Melanomas in reducing their sizes and/or number.
The sentinel lymph nodes (SLNs) are the first lymph nodes (LNs) to drain the tumor site and therefore the first LNs to bare metastases. Hence the importance to investigate these LNs for the best treatment strategy. Current-standard-of-care for melanoma patients with a melanoma stage of pT1b or higher, involve a surgical procedure, referred to as SLN biopsy (SLNB). The SLNB procedure involves a combined detection procedure using a radio-active tracer and blue dye followed by surgical dissection and evaluation of the LNs at the histopathology department. Due to the use of radioisotopes, this procedure suffers from several disadvantages such as limited availability, strict rules and regulations, degradation time in patient and radioactive load for user and patient. To overcome the limitations of a radioactive tracer, a magnetic SLNB was developed which is facilitated by super paramagnetic iron-oxide (SPIO) nanoparticles. This potentially offers numerous benefits making surgery planning more flexible: no exposure to radiation, easy accessibility of the tracer, long shelf life and long half time in the patient. However, the currently available magnetometer for intraoperative detection of SPIO-enhanced LNs is hampered by a relatively low detection depth, biological noise, and effects of surgical equipment. Therefore, surgeons need to switch to plastic or carbon equipment and the system needs to be balanced prior to each measurement, which increases the surgery time. A new and effective way to localize SPIOs is differential magnetometry (DiffMag). This patented detection principle, developed by MD&I group at University of Twente (UT), utilizes the nonlinear magnetic response of nanoparticles. An additional advantage of SPIOs is their visibility on MRI, which could provide mapping the SLNs preoperatively. Especially in patients with melanomas on the abdomen or back this would be very useful to see which lymph node stations are connected to the melanoma. In addition, studies have shown that SPIOs are absorbed into lymph nodes in different ways, depending on the presence of metastases. SPIO-enhanced MR lymphography could therefore provide an opportunity for a non-invasive preoperative assessment of nodal status. In this pilot study the investigators want to evaluate the clinical use of the DiffMag handheld probe. Moreover, the investigators want to map the lymph nodes (metastases) preoperatively using MR lymphography.
The purpose of this study is to establish a standardized process for obtaining digital pathological image information of ocular tumors; use modern pathological techniques to obtain the co-expression information of multiple biomarkers in the pathological tissues of ocular tumors, and finally construct standardized digital ocular tumors with biomarkers Pathology image database.
Diagnosis of melanoma involves physical examination of the lesion with many dermatologists adjunctively employing dermoscopes. The rate of misdiagnosis of melanoma remains significant, along with a high rate of referral to biopsy. Elucid Labs (Waterloo, Ontario) has developed a novel handheld, digital dermoscope with accompanying visualization and analysis software - the Artificial Intelligence Dermatology Assistant (AIDA™). Apart from collecting conventional demoscopic images, AIDA also collects images at various spectral bands. The aim of this study is to understand and quantify the value of this novel adjunctive information for dermatologists diagnosing atypical skin lesions.
