Filter by: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.
Background: - An experimental treatment for metastatic melanoma involves cell therapy, in which researchers take white blood cells (lymphocytes) from the tumor tissue, grow them in the laboratory in large numbers, and then use the cells to attack the tumor tissue. Before receiving the cells, chemotherapy is needed to temporarily suppress the immune system to improve the chances that the tumor-fighting cells will be able to survive in the body. In some studies of cell therapy, individuals who have received total body irradiation (TBI) in addition to the chemotherapy (in order to increase the length of time that they do not produce white blood cells) seem to have a slightly better response to the treatment, but it is not known if adding radiation to the cell therapy will cause a better response for all individuals. Researchers are interested in comparing cell therapy given with the usual chemotherapy to cell therapy given with the usual chemotherapy and TBI. Objectives: - To compare the effectiveness of cell therapy given with chemotherapy to cell therapy given with chemotherapy and total body irradiation in individuals with metastatic melanoma. Eligibility: - Individuals at least 18 years of age who have been diagnosed with metastatic melanoma. Design: - Participants will be screened with a physical examination, medical history, blood tests, and tumor imaging studies. - Participants will be divided into two groups: cell therapy with chemotherapy alone (group 1) or cell therapy with chemotherapy plus TBI (group 2). - All participants will provide a tumor sample from either surgery or a tumor biopsy for white blood cell collection. - Participants will have leukapheresis to collect additional white blood cells for cell growth and future testing, and TBI group participants will also provide stem cells to help them recover after radiation. (TBI participants who cannot provide enough stem cells will be moved to the non-radiation treatment group.) - Participants will have chemotherapy with cyclophosphamide (two treatments over 2 days) and fludarabine (five treatments over 5 days) starting 7 days before the cell therapy. Participants in the TBI group will also have TBI for the 3 days immediately before the cell therapy. - All participants will receive the white blood cells, followed by high-dose aldesleukin every 8 hours for up to 5 days after the cell infusion to help keep the therapy cells alive and active. Participants will also have injections of filgrastim to stimulate blood cell production, and participants in the TBI group will also receive their stem cells. - Participants will take an antibiotic for at least 6 months after treatment to prevent pneumonia, and will be asked to return for regular monitoring and followup visits for at least 5 years to evaluate the tumor s response to treatment.
This phase I trial studies the side effects and best dose of sorafenib tosylate when given together with riluzole in treating patients with solid tumors or melanoma that has spread to other places in the body and usually cannot be cured or controlled with treatment. Riluzole may stop or slow the growth of tumor cells. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving riluzole together with sorafenib tosylate may kill more tumor cells.
RATIONALE: Photodynamic therapy uses a drug that becomes active when it is exposed to a certain kind of light. When the drug is active, cancer cells are killed. Photodynamic therapy using methyl-5-aminolevulinate hydrochloride cream may be effective against skin cancer. PURPOSE: This phase I trial is studying the side effects and best dose of photodynamic therapy with methyl-5-aminolevulinate hydrochloride cream in determining pain threshold patients with skin cancer
This randomized phase III trial studies ipilimumab to see how well it works compared to high-dose interferon alfa-2b in treating patients with high-risk stage III-IV melanoma that has been removed by surgery. Immunotherapy with monoclonal antibodies, such as ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Interferon alfa-2b may interfere with the growth of tumor cells and slow the growth of melanoma and other cancers. It is not yet known whether ipilimumab is more effective than interferon alfa-2b in treating patients with melanoma.
This study will look at high frequency ultrasound as a medical imaging modality and apply it to skin lesions. Elastography is an ultrasonic method of looking at the hardness of an area. We will use this to try and differentiate between benign and cancerous skin lesions.
This randomized phase II trial studies how well aldesleukin with or without ziv-aflibercept works in treating patients with stage III-IV melanoma that cannot be removed by surgery. Aldesleukin may stimulate the white blood cells to kill cancer. Ziv-aflibercept may stop the growth of melanoma by blocking blood flow to the tumor. It is not yet known whether aldesleukin is more effective with or without ziv-aflibercept in treating melanoma.
The purpose of this study is to evaluate the efficacy of cryosurgery during continuing imiquimod application in the treatment of basal cell carcinoma of the skin.
Malignant Melanoma is a deadly skin cancer that can be cured if diagnosed early. To date atypical pigmented skin lesions are diagnosed by appearance alone and many moles and lesions are excised unnecessarily and on the other hand malignant lesions are missed and diagnosed too late. In this study a protein conjugated to a florescent dye is spread on a suspicious pigmented lesion, the hypothesis is that this protein binds to malignant cells only and thus with a special camera that picks up the dye we can find pigmented lesions with early malignant transformation.
RATIONALE: Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as vinorelbine ditartrate, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving temsirolimus together with vinorelbine ditartrate may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of giving temsirolimus and vinorelbine ditartrate together in treating patients with unresectable or metastatic solid tumors.
