Filter by:The investigators' hypothesis is that cutaneous melanoma, melanoma in situ, dysplastic nevi and benign nevi all differ in not only clinical characteristics but also molecular and genotypic characteristics. Patients with suspected primary cutaneous melanoma or a differential diagnosis, or secondary melanoma can be asked to participate in the first part of the project and patients with suspected or confirmed secondary (spread) melanoma can be included in the second part of the study. Participants included in the study answer a validated questionnaire regarding epidemiological and phenotypic factors to map medical history, prior UV exposure, family history of melanoma and/or other cancer types, skin type, smoking habits, alcohol use and quality of life. Blood samples (whole blood) are collected before primary local excision and before secondary surgical procedures as well as during follow up of patients with secondary disease and oncologic treatment. During local excision of the primary pigmented skin lesion, full-thickness skin punch biopsies are taken by trained dermatologists. The biopsies, in the lesion and next to the lesion in the normal skin of the suspected melanoma, are taken, snap frozen and stored deep frozen. The primary lesions are documented by accurate imaging methods prior to excision. Tissue samples from suspected or confirmed secondary melanomas are collected mainly through surgical and core needle biopsies before, during and after treatment and in case of disease progress or treatment failure. Tissue samples are snap-frozen and stored in the same way as samples from primary melanomas. Comprehensive questionnaire based, imaging-based information, as well as histologic information provided from the pathologist report is included and stored in a secure database. All the information in the database, along with information from molecular analysis of tissue and/or blood samples will then be used to find objective, molecular and clinical differences in melanoma, melanoma in situ, dysplastic and benign nevi along with potential information of biological aggressivity of both primary and secondary melanoma in order to find more objective diagnostic markers.
Prospective non-interventional study of clinical outcomes and biomarkers in patients with stage 0-IV skin melanoma in real clinical practice
A Multicenter, Prospective, Low-interventional Clinical Study Evaluating on mobile application validation ("ProRodinki") in assessing the risk of skin malignant neoplasms
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.
This study is meant to assess the use of intralesional IL-2 to modulate the immunological response to suspected melanoma, or melanoma in situ, in an effort to increase lymphocyte infiltration and decrease disease metastasis. Patients that are clinically diagnosed with suspected Melanoma or Melanoma in situ will be assigned to either a treatment or control arm. The treatment group will be subjected to two intralesional IL-2 injections, whereas the control group will be subjected to two intralesional injections of saline. The proteomic and metabolomic profiles of both groups will be analyzed using urine and blood samples in an effort to assess the systemic immunological response, if any, to the treatment. Also, upon disease confirmation and staging by a qualified pathologist, lesions will be assessed for lymphocyte infiltration using immunohistochemical methods. This study will determine whether pre-treatment of IL-2 on lesions (clinically diagnosed as melanoma or melanoma in situ) is effective in generating an adaptive immune response, and whether that immune response may play a role in preventing disease metastasis.
The purpose of this study is to determine if immunofluorescence (IF) can effectively identify features of malignant melanoma in situ, on sun-damaged skin, in the setting of Mohs Micrographic Surgery.
