Filter by:This pilot phase I trial studies vitamin D levels in the skin of healthy subjects after oral supplementation. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of cholecalciferol, a vitamin D, may keep skin cancer from forming.
Knowledge gap: Does the choice of anaesthetic affect outcome for cancer surgery? Aim: To retrospectively examine possible associations (Cox Multiple Regression) between survival from breast-, colorectal-, or skin cancer and the choice of hypnotic used during surgery, ahead of a prospective randomised controlled trial. Hypotheses: One- and five-year survival will be significantly higher after radical breast-, colorectal-, or skin cancer surgery in patients given the intravenously administered hypnotic propofol than in patients given the inhalational hypnotic sevoflurane. Method: To merge two registers, of which one holds demographic- anaesthetic-, and surgical data from 6 303 patients operated on at the three mentioned anatomical locations at the Central Hospital in Vasteras, Sweden during a twelve year period (1998-2009). Of these minimum 4 500 operations would be due to cancer. This register is unique, in that it contains both types of anaesthesia. The other register holds survival data (date and cause of death), stored at the Regional Oncologic Center in Uppsala. The choice of anaesthetic will be validated by controlling each patient's anaesthetic paper file, concomitantly with extraction of details from anaesthesia and surgery, such as the functional classification of each patient (according to American Association of Anesthesiologists), co-morbidity, duration of anaesthesia and surgery, amount of blood loss and possible transfusion. Current knowledge: Different anaesthetics have opposite effects on the immune system and on the DNA. There is a well-established association between the state of the immune system and cancer growth, which in turn will influence survival. There is also an association between DNA damage and cancer development. Inhalational anaesthetics, e.g. sevoflurane, act pro-inflammatory, and they are also proven to be genotoxic. Propofol is anti-inflammatory and anti-oxidative, and it is not genotoxic. Objective: Strengthen the hypotheses, and get statistics for a proper power calculation in advance of a multi-centre, prospective, randomised, controlled trial. Impact: General anaesthesia is an indispensable part of radical cancer surgery. Undesired effects from anaesthesia on survival has strong relevance for the over all cancer treatment.
The investigators are conducting a study to provide evidence about the comparative effectiveness of mailed, tailored intervention materials on cancer prevention behavioral outcomes. The investigators will send out three (3) tailored mailings for participants who are assigned to the intervention group. Second, during the eligibility screening, the investigators will be assessing the relative yield and functioning of two risk assessment tools (BRAT and FEARS) on determining an individual's level of risk for skin cancer.
MicroRNAs (miRNAs) are very small endogenous RNA molecules about 22-25 nucleotides in length, capable of post-transcriptional gene regulation. miRNAs bind to their target messenger RNAs (mRNAs), leading to cleavage or suppression of target mRNA translation based on the degree of complementarity. miRNAs have recently been shown to play pivotal roles in diverse developmental and cellular processes and linked to a variety of skin diseases and cancers. In the present study, the investigators examines the expression profiles of the microprocessor complex subunit DGCR8 and the RISC components TARBP1, TARBP2, argonaute-1, argonaute-2 and PACT in epithelial skin cancer and its premalignant stage.
We hope to determine the importance of different genes (including B receptors) in anthracycline-induced cardiomyopathy. This has important benefits to patients exposed to anthracyclines, as this could help determine whether certain individuals have increased susceptibility to cardiac injury.
Background: - Adoptive cell therapy involves taking white blood cells called lymphocytes from patients' tumors, growing them in the laboratory in large numbers, and then giving the cells back to the patient to allow the cells to attack the tumor. Because this process is lengthy and difficult to perform, researchers have been developing improved means of performing adoptive cell therapy. Researchers are now interested in comparing adoptive cell therapy with the standard treatment for metastatic melanoma (skin cancer). Objectives: - To compare the effectiveness of adoptive cell therapy with standard high-dose aldesleukin as a treatment for metastatic melanoma. Eligibility: - Individuals 18 years of age or older who have been diagnosed with metastatic melanoma and have not previously received aldesleukin therapy or cell therapy for their disease. - Participants must have at least one tumor that can be easily removed as part of the treatment procedure. Design: - Participants will be screened with a full medical history, physical examination, blood and urine tests, and imaging scans to evaluate tumor size and treatment options. - Participants will be separated into two groups, in which one group will have adoptive cell therapy and one will have aldesleukin treatment. - Adoptive Cell Therapy - Participants will have a tumor sample taken in order to collect white blood cells for treatment. Participants whose tumors do not provide sufficient white blood cells may be switched to the aldesleukin-only treatment group. - The white blood cells will be grown in the laboratory for several weeks. - Prior to receiving cell therapy, participants will receive chemotherapy for 7 days to improve the chances of successful treatment. - Participants will have cell therapy followed by high-dose aldesleukin treatment every 8 hours for up to 5 days. This treatment will be followed by 1 to 2 weeks of recovery time as an inpatient at the clinical center. - Participants will be evaluated at 12 weeks following the start of the study, every 2 to 3 months for the first year, every 6 months for the next 5years, and then yearly thereafter.. - Standard Aldesleukin Treatment - Participants will have high-dose aldesleukin treatment every 8 hours for up to 5 days (one cycle of treatment), and will have a second cycle of treatment 7 to 10 days after the first cycle. - If tests show that the tumors have grown, participants will be offered the chance to have additional cycles of aldesleukin, or begin a cell therapy treatment. - Participants will be evaluated at 12 weeks following the start of the study, every 2 to 3 months for the first year, every 6 months for the next 5years, and then yearly thereafter.
Basal cell carcinomas (BCCs) are the most common human cancer in the US and affect over 1 million people. There is no effective drug to prevent basal cell carcinomas of the skin. We hope to learn if an oral anti-fungal drug, itraconazole, might inhibit a marker of proliferation and a biomarker (tumor signaling pathway) of BCC development. Itraconazole is an FDA-approved drug for the treatment of fungal infections of the skin, and has been used for the past 25 years with relatively few side effects. It has been shown in mice to reduce a BCC biomarker and to reduce growth of BCCs. Thus, it may reduce BCC growth in humans.
Skin cancer incidence continues to rise and ultraviolet radiation (UVR) in sunlight is the principal cause. Solar UVR can promote cancer development through its ability to suppress the immune system. The purpose of this study is to determine whether dietary supplementation with omega-3 polyunsaturated fatty acids can protect human skin from UVR-induced immunosuppression.
There is little information on the effect of oral bioactive compounds on human skin clinically despite evidence of a beneficial effect from laboratory studies. The aim of this study is to examine the effect of oral bioactive compounds (green tea and vitamin C) on the health of human skin by measuring markers of skin health directly and skin nutrient uptake.
Background: - Melanoma antigen recognized by T-cells (MART-1) and gp100 are two genes found in melanoma cells. An experimental procedure developed for treating patients with advanced melanoma uses these genes and a type of virus to make special cells called anti-MART-1 and anti-gp100 cells, which are designed to destroy the patient's tumor. The cells are created in the laboratory using the patient's own tumor cells or blood cells. - The procedure also uses one of two vaccines-the anti-MART-1 peptide or the anti-gp100 peptide-to stimulate cells in the immune system that may increase the effectiveness of the anti-MART-1 and anti-gp100 cells. Both vaccines are made from a virus that is modified to carry a copy of the MART-1 gene or gp100 gene. The virus cannot cause disease in humans. Objectives: - To evaluate the safety and effectiveness of anti-MART-1 and anti-gp100 cells and peptide vaccines for treating patients with advanced melanoma. Eligibility: - Patients 18 years of age with metastatic melanoma for whom standard treatments, including aldesleukin (IL-2) therapy to boost immune response, have not been effective. Design: - Participants have an initial evaluation with complete medical history, as well as scans, x-rays, and other tests as directed by researchers. Most of the treatments for this study will be given on an inpatient basis. - Before the treatment begins, participants will undergo leukapheresis (removal of selected blood cells) to obtain cells for preparing the anti-MART-1 and anti-gp100 cells, and for later stem cell transplantation. - Preinfusion treatment: 5 days of chemotherapy and 2 days of total-body irradiation to prepare the immune system for receiving the anti-MART-1 and anti-gp100 cells. - Infusion of cells, followed by IL-2 treatment to improve immune response. IL-2 is given as a 15-minute infusion through a vein every 8 hours for a maximum of 15 doses (over 5 days). - After the cell infusion, participants will be divided into two groups and will receive either the gp100 peptide or MART-1 vaccine, given once a week for 3 weeks. Participants will also have stem cell transplantation (from previously collected stem cells) to promote cell survival. - Periodic follow-up clinic visits after hospital discharge for physical examination, review of treatment side effects, laboratory tests and scans every 1 to 6 months.
