Active clinical trials for "Skin Neoplasms"

This is a multicenter prospective observational clinical investigation with a medical device. The purpose of this study is to develop and validate of a new type of digital dermatoscope with automatic decision support algorithms. By means of this study a better insight can be gained of the current performance and workflow in clinical dermatoscopy. This knowledge will be used to further improve the developed technology.

This study is to evaluate the psychological well-being in patients diagnosed with skin cancer (melanoma and Squamous Cell Carcinoma (SCC) in the face) at the time of diagnosis and after treatment. Patients diagnosed with primary melanoma and/or SCC and/or infiltrative basal cell carcinoma on the face subjected to surgical treatment (excision or Mohs Surgery) will be included. All patients will receive questionnaires.

A hospital based cross-sectional study was conducted from 2017 to February 2021. Clinical history, examination and histopathological variants were collected from medical files and pathology reports. Confirmation of pathology was done in all the patients visiting skin and plastic surgery department with suspected lesions.

This project aims to validate ex vivo the use of the OCTAV® prototype integrating the "dermoscope" function before an in vivo application, by comparing images obtained by the OCTAV® prototype integrating the "dermoscope" function with the histological sections of a skin tumor excision corresponding to them exactly, at the same level.

We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We make it easy for patients to contribute to research for medical conditions that matter most to them, regardless of their location or ability to travel.

Introduction: Cancer is a serious disease with a high mortality rate in the world and in Turkey today. Skin cancer, which is among the most common types of cancer, is increasing every year in many countries in the world such as Australia, America, New Zealand, and in Turkey. The most dangerous type of skin cancer with a high mortality risk is melanoma. According to the Turkish Cancer Statistics, melanoma is among the ten most common cancer types among children aged 0-14 years. This situation constitutes a public health problem. Aim: This research was planned to determine the effect of education given to parents of secondary school students about skin cancer, Skin Self Examination (SSE) and Sun Protection Behaviors on their children's sun protection behaviors.

The goal of this clinical trial is to assess the feasibility and safety of oral nicotinamide (NAM; a derivative of vitamin B3 [niacin]) and vitamin A in a high-risk population of kidney transplant recipients with a history of skin cancer to generate preliminary data for future cancer prevention clinical trials.

This study investigates the bone-related side effects caused by immunotherapy drugs such as nivolumab and pembrolizumab in patients with melanoma. Nivolumab and pembrolizumab are immunotherapy drugs (drugs that boost your immune system) used to prevent cancer from coming back in patients with melanoma. Specifically, researchers want to learn if there is any relationship between receiving immunotherapy and bone density (thickness) measured by a dual-energy X-ray absorptiometry (DXA) scan or bone turnover markers (which indicate levels of bone loss) found in the blood. This study may provide researchers with more information on bone loss and may help prevent bone loss in future patients.

Background: The National Cancer Institute (NCI) Surgery Branch has developed an experimental therapy that involves taking white blood cells from patients' tumors, growing them in the laboratory in large numbers, and then giving the cells back to the patient. These cells are called Tumor Infiltrating Lymphocytes, or TIL and we have given this type of treatment to over 100 patients. In this study, we are selecting a specific subset of white blood cells from the tumor that we think are the most effective in fighting tumors and will use only these cells in making the tumor fighting cells. Objective: The purpose of this study is to see if these specifically selected tumor fighting cells can cause melanoma tumors to shrink and to see if this treatment is safe. Eligibility: - Adults age 18-70 with metastatic melanoma who have a tumor that can be safely removed. Design: Work up stage: Patients will be seen as an outpatient at the National Institutes of Health (NIH) clinical Center and undergo a history and physical examination, scans, x-rays, lab tests, and other tests as needed Surgery: If the patients meet all of the requirements for the study they will undergo surgery to remove a tumor that can be used to grow the TIL product. Leukapheresis: Patients may undergo leukapheresis to obtain additional white blood cells. {Leukapheresis is a common procedure, which removes only the white blood cells from the patient.} Treatment: Once their cells have grown, the patients will be admitted to the hospital for the conditioning chemotherapy, the tumor infiltrating lymphocytes (TIL) cells and aldesleukin. They will stay in the hospital for about 4 weeks for the treatment. Follow up: Patients will return to the clinic for a physical exam, review of side effects, lab tests, and scans about every 1-3 months for the first year, and then every 6 months to 1 year as long as their tumors are shrinking. Follow up visits take up to 2 days. ...

Background: Immunotherapy drugs use a person s own immune system to help fight cancer. These drugs work better for some people than others. The drug M7824 has helped some people with cancer. But it can cause side effects. Researchers want to learn all the side effects that M7824 can cause. Once they do, they can prevent or reduce these side effects in future cancer treatments. This will lead to better overall outcomes for people with cancer. Objective: To make a thorough list of adverse events in people with cancer being treated with systemic therapies including M7824 at the National Cancer Institute (NCI). Eligibility: Participants previously enrolled in NCI protocols #15-C-0179 and #18-C-0056 Design: All needed data have already been collected. These data are stored in existing records and databases. Researchers will review the medical records of adults with cancer who were enrolled in the above protocols. The data collected will be relevant to the specific objectives being addressed. Data will be collected only if 2 conditions are met. One, the principal investigator gave permission for use of the data gathered in the trial. Two, the participants of the trial did not opt out of future use of the data. Other protocols may be added. This will be done with an amendment. ...
