Active clinical trials for "Melanoma"

An observational, non-interventional registry study to collect real-world data from people living with melanoma and its treatment, which will be available to researchers to further the knowledge of melanoma and improve patient care.

The worldwide incidence of cutaneous melanoma has been increasing for the last 30 years in western populations. Among all melanomas, those located on the head and neck are more frequent than expected regarding the surface of this anatomical area, occur in older subjects than melanomas at other sites and have a worse prognosis than melanomas at other sites. The question whether head and neck melanomas could be a distinct entity has been debated.

The objective of this project is to evaluate the presence of melanoma quiescent or initiating clonal cells in peritumoral healthy tissue displaying the same molecular signature than those of the tumor/metastasis and to correlate this presence to the prognostic value.

This study investigated the visual and anatomical outcomes, tumor control, tumor recurrence, distant metastasis and cancer free survival in patients affected by uveal melanoma and undergoing Ru-106 plaque brachytherapy between February 2011 and March 2020

Melanoma incidence is increase in global population and number of transplantation also. However immunosuppressor increase recurrence risk of melanoma. There are more and more cases of eligible patients to transplant with an antecedent of melanoma. There is no guideline yet. Main objective is survival time without melanoma recurrence in this population to do guideline of time limit or not between melanoma and transplantation by stage.

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).

This was a retrospective cohort study using the PharMetrics database. The analysis was conducted using the most recent 5 years of data from the database, January 1, 2015, to October 30, 2020. Included patients were followed for outcome evaluation from the index date (first prescription of treatment, immunotherapy [IO], or targeted therapy [TT] following diagnosis of non-metastatic malignant melanoma and evidence of first lymph node resection), until the first occurrence or end of continuous eligibility or end of the study period.

Identify the best combination of predictive variables that influence ionizing radiation dose and improved image quality through analysis and quantification of PET-CT images in simulators and patients.

The purpose of this study is to calculate the sensitivity and specificity of a novel imaging device and associated software algorithm in detecting early stage melanoma versus nevi of the skin. The instrument, which was invented by the PI, for the purposes of this study, will be loaned to three external (to Rockefeller) institutions and used on patients who are scheduled for biopsy of pigmented lesions. The purpose of correlating the output screening result of the novel device and the output diagnosis of the gold standard histology analysis procedure is so that these two diagnoses can be compared to generate the number of true positives, true negatives, false positives and false negatives for the novel device. The purpose of disseminating the device to the external institutions is to achieve the appropriate power such that the specificity can be evaluated at 99% sensitivity. The rationale for the power needed in the study is that in order to be clinically useful, the device needs to be extremely sensitive (i.e. 99%) because false negative diagnosis is a dangerous situation, leading to potential progression of melanoma, the most deadly form of skin cancer.

All patients will undergo dermoscopic diagnosis and be documented with a video image storing. The diagnosis based on dermoscopy will be immediately documented. Then, as a second diagnostic procedure, fluorescence diagnostics based on the two photon excitation from a dye-laser will be performed. The classification as non-melanoma or malignant melanoma by the medical device LIMES will also be documented immediately. Afterwards, the lesion will be excised and undergo histopathologic examination by the respective histopathologist of the participating centers. The histopathologic diagnosis will serve as gold standard for subsequent evaluations of the diagnostic accuracy.
