Filter by:100 subjects who have a family history of pancreatic cancer (PC), or known genetic syndromes associated with increased risk of pancreatic cancer, will be followed for five years. This data will be used to determine the pancreatic cancer and precancerous lesion detection rate in High Risk Individuals (HRIs). Subjects may agree to annual imaging and annual biomarkers or to biomarkers only.
Early detection testing is recommended for individuals at elevated risk for the development of Pancreatic Cancer. This Protocol will define sufficiently elevated risk as either equal to or greater than five times the general population risk, or five times the average risk (1.5%) of developing pancreatic cancer by age 70; that is a 7.5% lifetime risk. Our inclusion criteria has a strong focus on the risk for pancreatic cancer imparted by the presence of hereditary cancer genes, as well as by family history. Enrolled subjects will undergo Endoscopic Ultrasound (EUS) alternating with Magnetic Resonance Imaging (MRI), every six to 12 months, for up to 5 years.
This is a pilot study to see if oral administration of freeze dried, powdered broccoli sprouts have any effect on whether moles end up becoming melanoma.
A novel infrared imaging tool to aid in the clinical detection of atypical pigmented lesions and melanoma is developed. Goals include evaluation of the utility of high-resolution infrared scanning of cutaneous lesions in the diagnosis of pigmented lesions and the identification of high-risk lesions and melanomas.
The investigators' goal is to identify the mutation in the gene that is responsible for the development of segmental dysplastic nevi. To identify the gene the investigators may use a candidate gene approach (i.e. sequence specific genes that are thought to be involved: NRAS, BRAF, etc) or a genome-wide approach trying to implicate regions in the genome (Loss-of-heterozygosity or copy number changes on comparative genomic hybridization).
The purpose of the potential research study participant registry is to keep potential research subjects informed about any future research studies in which they may meet the criteria for enrollment. The purpose of this study is also to assist current and future clinical trials with recruitment of subjects.
The purpose of this study is to evaluate the safety and effectiveness of an experimental 20% betulinic acid ointment (BA ointment) as a treatment for dysplastic nevi with the potential to transform into melanoma.
During the course of a case-control study of melanoma conducted at the Bufalini Hospital, Cesena, Italy in the years 1994-1996, 20 families with 2 or 3 melanoma cases were identified and studied. The area where the study was conducted showed the steepest increase in melanoma incidence in Mediterranean populations between the years 1987 and 1997. Clinical characteristics of melanoma in the families studied were similar to those typically described in fair-skinned populations, but no relevant mutations in the coding regions of known candidate genes from melanoma have been found. Lack of findings could be due to the modest number of families and the small number of affected CMM cases examined. We cannot exclude the possibility of alterations in introns, splicing sites or promoter regions. Also epigenetic factors could affect the expression of the gene products we studied. Alternatively, germline alterations of a gene(s) other than the candidate genes we analyzed may play an important role in melanoma predisposition in this population. A large number of families is needed to test these hypotheses. These additional families could provide an important contribution to the understanding o melanoma development. In fact, this population does not generally have the host characteristics that are usually associated with higher risk for melanoma (e.g., light skin color, red hair, blue eyes, multiple freckles, tendency to sunburn, etc.) but do have a relative high frequency of dysplastic nevi and melanoma. The main objective of this study is to recruit more families at the Bufalini Hospital, Cesena, Italy in order to reach a larger sample size. Recently, 16 potential melanoma-prone families have been identified through patient's or physicians' referrals by the Dermatologists at the Bufalini Hospital. The dermatologists have maintained close relationships with members of these families and are confident that these subjects would be willing to participate in a study if contacted. The first goal of our study is to contact this family group and verify their willingness to participate in the study. In addition, new families could be identified and recruited. We propose to conduct a pilot project. We estimate recruitment of approximately 25 families with 2 or more melanoma cases in first -degree relatives over a one-year period, including the 16 families already identified and approximately 10 new kindreds. At the end of the pilot phase we will determine the feasibility of continuing recruitment.
This study will investigate how genetic and environmental factors contribute to the development of melanoma, a type of skin cancer, and related conditions. Individuals >=4 weeks with a personal or family history of melanoma or atypical spitzoid/Spitz tumor may be eligible for this study. Participants will: - Fill out one or two questionnaires about their personal and family medical history. - Provide written consent for researchers to review their medical records and pathology materials related to their care and those of deceased relatives with melanomas, tumors, cancer, or other related illnesses for whom they are the next-of-kin or legally authorized representative. - Donate a blood or cheek cell sample to be used for genetic studies. (The blood sample is collected through a needle in an arm vein. The cheek cell sample is obtained either by gently brushing the inside of the mouth with a soft brush or by swishing a tablespoon of mouthwash and then spitting it into a container.) - Undergo a skin biopsy (removal of a small piece of skin tissue) for genetic study. For this procedure, the area of skin to be removed is numbed with a local anesthetic and a 1/4-inch piece of skin is excised with a cookie cutter-like instrument. The wound is then covered with a band-aid. Participants may be asked to travel to the NIH Clinical Center for evaluation, including a medical history, physical examination, and some of the following procedures: - Full body skin examination to evaluate the type and number of moles and document any evidence of sun damage to the skin. The examination involves all the skin from the scalp to the bottoms of the feet. After the examination, a medical photographer will photograph the skin, with close-ups of skin lesions marked by the examiner. If there are parts of the skin the participant does not want examined or photographed, he or she can tell the examiner. - Blood draw of about 120 milliliters (4 ounces) or less - Skin biopsy - Cheek cell sample - X-rays, ultrasound and magnetic resonance imaging (MRI) studies to detect tumors or changes in tumors or other types of changes in specific tissues. MRI is a diagnostic test that uses strong magnetic fields and radiowaves to examine body tissues. The subject lies on a table that is moved into a large tunnel-like machine (the scanner) for about 45 minutes to 1 hour. When the tests are finished, a doctor will discuss the results with the participant and the need, if any, for clinical follow-up.
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of tretinoin and/or fenretinide may be an effective way to prevent the recurrence or further development of dysplastic nevus syndrome. PURPOSE: Randomized phase II trial to compare the effectiveness of tretinoin with or without fenretinide in treating patients with dysplastic nevus syndrome.
