Treatment With Intravitreal Avastin for Large Uveal Melanomas
Summary
The purpose of this study is to test the safety and effectiveness of Avastin introduced into the inside of the eyeball in causing shrinkage of the uveal melanoma (tumor of the eye). Avastin is an anti-cancer drug specially designed to shrink blood vessels within tumors.

Medical and Biotech [MESH] Definitions
Melanoma, Amelanotic
An unpigmented malignant melanoma. It is an anaplastic melanoma consisting of cells derived from melanoblasts but not forming melanin. (Dorland, 27th ed; Stedman, 25th ed)
Melanoma, Experimental
Experimentally induced tumor that produces MELANIN in animals to provide a model for studying human MELANOMA.
Ciliary Body
A ring of tissue extending from the scleral spur to the ora serrata of the retina. It consists of the uveal portion and the epithelial portion. The ciliary muscle is in the uveal portion and the ciliary processes are in the epithelial portion.
Hutchinson's Melanotic Freckle
A cellular subtype of malignant melanoma. It is a pigmented lesion composed of melanocytes occurring on sun-exposed skin, usually the face and neck. The melanocytes are commonly multinucleated with a "starburst" appearance. It is considered by many to be the in situ phase of lentigo maligna melanoma.
Cysteinyldopa
Found in large amounts in the plasma and urine of patients with malignant melanoma. It is therefore used in the diagnosis of melanoma and for the detection of postoperative metastases. Cysteinyldopa is believed to be formed by the rapid enzymatic hydrolysis of 5-S-glutathionedopa found in melanin-producing cells.
Clinical Trials
Tilting of Radioactive Plaques After Initial Accurate Placement for Treatment of Uveal Melanoma
Plaque radiotherapy is a common treatment for uveal melanoma. However, local failure has been reported in up to 20% of patients. We use intraoperative ultrasonography at plaque insertion...
Intravitreal Ranibizumab for the Prevention of Radiation Maculopathy Following Plaque Radiotherapy
Uveal Melanoma is the most common primary intraocular malignancy in adulthood. Eye preserving treatments can deliver equivalent life prognosis in the management of small and medium sized...
Melanoma Inhibitory Activity (MIA): A Serological Marker for Metastatic Uveal Melanoma
Uveal Melanoma is the most common primary intraocular tumor in adults. Most tumors metastasize to the liver. So far no sensitive or specific serological tumor marker is routinely used. The...
Patients with uveal melanoma metastatic to the liver will be treated with embolization of the hepatic artery every 4 weeks. GM-CSF (granulocyte-macrophage colony simulating factor) or norm...
RATIONALE: Drugs used in chemotherapy, such as dacarbazine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Recombi...
PubMed Articles
Purpose: Somatic mutations in codon 209 of the GNAQ gene are the first initiating events to be identified in uveal melanoma. The aim of the study was to search for GNAQ209 mutations in conjunctival me...

PURPOSE: To report sequential bilateral uveal melanoma in an arc welder. METHODS: Case report. RESULTS: A 57-year-old Caucasian male, with a 15-year profession of arc welding, was found to have an iri...
Tight junction-associated signaling pathways modulate cell proliferation in uveal melanoma.
Purpose: To investigate the role of tight junction (TJ) associated signaling pathways in proliferation of uveal melanoma. Methods: Human uveal melanoma cell lines overexpressing the TJ molecule blood...
Uveal melanoma arises from melanocytes of the uveal tract (iris, ciliary body and choroid) and represents the most common intraocular malignancy in adults. Some rare clinical situations (young age at...
Detection of M2 macrophages in uveal melanoma and relation with survival.
Purpose: The presence of high numbers of infiltrating macrophages in uveal melanoma is associated with a bad prognosis. However, several types of macrophages are known to exist, of which the M2 macrop...
