In Vivo Confocal Microscopy Study of Pigmented Conjunctival Lesions
NevusRacial Melanosis2 moreThis study aims to validate the use of laser in vivo confocal microscopy as an early diagnostic and differentiation tool of pigmented conjunctival lesions, evaluate the efficacy of in vivo confocal microscopy for follow-up (as a visualizing tool) after tumor resection for early detection of tumor recurrence, and to evaluate the use of in vivo confocal microscopy in evaluation of response to treatment. The modified technique with Heidelberg Retina Tomography (HRT) confocal microscopy and anterior segment optical coherence tomography (OCT) are non-invasive, no-touch, imaging techniques that may help in differentiation of benign lesions like nevi or racial melanosis, from malignant lesions like primary acquired melanosis and malignant melanomas. The OCT will potentially allow to estimate tumor depth in vivo as preliminary studies have shown.
A Study of Sorafenib in Patients With Chemonaive Metastatic Uveal Melanoma
Uveal MelanomaUveal melanoma is the most common primary intra-ocular malignancy in adults with an incidence of 0.6 - 0.7 per 100,000 per year. Prognosis of metastatic uveal melanoma is poor. In retrospective analyses a median survival time after detection of metastases of 5 months (Flaherty et al, 1998) and 7 months (Kath et al, 1993) was reported. For patients receiving no treatment reported median survival was 2.0 months compared with 5.2 months for those receiving treatment for metastases (Gragoudas et al, 1991). Up to now there is no established treatment of metastatic uveal melanoma. Some therapeutic approaches with locoregional treatment or systemic chemotherapy have been undertaken: In case of metastatic disease which is confined to the liver in about 85% of patients with uveal melanoma surgical resection led to a median survival of 14 months (Mariani et al, 2009) or 19 months and a 5-year survival rate of 22% in a selected patient population (Adam et al, 2006). As locoregional treatment option treatment with fotemustine via direct intra-arterial hepatic infusion was investigated and led to a median survival of 15 months (Peters et al, 2006). This was not a randomized trial, but a report on 101 consecutive treated patients. Additional debulking surgery was performed whenever feasible. A randomized phase III trial comparing intra-arterial hepatic fotemustine administration with intravenous systemic fotemustine and overall survival as primary endpoint is still ongoing (EORTC 18021). Thus, no systemic chemotherapy is approved for metastatic uveal melanoma. Although no specific genes have been linked to the pathogenesis of uveal melanoma, preclinical studies suggest potential benefit of inhibitors of Bcl-2, ubiquitin-proteasome, histone deactylase, mitogen-activated protein kinase and phosphatidylinositol-3-kinase-AKT pathways, and receptor tyrosine kinases. Thus, sorafenib as inhibitor of b-Raf and Raf-1 (c-Raf or c-Raf-1), pro-angiogenic vascular endothelial growth factor receptor (VEGFR), and platelet-derived growth factor receptor (PDGFR) may potentially lead to a benefit for patients with metastatic uveal melanoma in terms of disease control and prolongation of survival.
A Phase II Study of Imatinib Versus Interferon as Adjuvant Therapy in KIT-mutated Melanoma
MelanomaThe purpose of this study is to compare the relapse free survival and overall survival of Imatinib (Gleevec) or high dose Interferon (Intron) in treating melanoma which has primary tumor and regional lymphonode (if have) removed in patients whose disease carries a c-kit mutation. It is assumed that Gleevec may be more effective on relapse free survival as the adjuvant treatment compared with Interferon.

Malignant Melanoma of Skin Stage IIIMalignant Melanoma of Skin Stage IVTitle: Vaccination with autologous dendritic cells loaded with autologous tumor lysate or homogenate combined with immunomodulating radiotherapy and/or preleukapheresis IFN-alfa in patients with metastatic melanoma: a randomized "proof-of-principle" phase II study.

Biomarker Correlates of Hypoxia in Metastatic Melanoma
MelanomaSkin CancerThe purpose of this study is to determine if magnetic resonance imaging (MRI) or positron emission tomography (PET) imaging can be used to help doctors determine how much oxygen a tumor is getting. Hypoxyprobe will be used to determine the levels of oxygen post-surgery in the current study. If the study is successful, then imaging can be used to determine a tumor's oxygen status even in patients who are not getting surgery. Investigators want to find out how much oxygen is in the participants tumor based on how much pimo is present, and correlate this with the results of their MRI and 18F-fluoromisonidazole (FMISO) PET scan. This study is also testing the investigational radioactive substance known as FMISO. FMISO is used during PET scans to help doctors see how much oxygen a tumor is getting. Participants might be asked to participate in an optional PET scan using FMISO.
TTT Versus TTT and Triamcinolone to Decrease Exudation in Choroidal Melanoma After Proton Beam Therapy...
Exudative Retinal DetachmentUveal MelanomaProton beam therapy is a safe irradiation modality for choroidal melanoma. But often after irradiation the exudation increases resulting in an exudative retinal detachment requiring vitreoretinal surgery. It is known that intravitreally injected triamcinolone and TTT is capable to decrease the exudation. If there is any advantage in a combined treatment this study will investigate.
