INTRODUCTION Compared with other tumors, melanoma has displayed one of the largest increases in incidence in recent years, and it is known to have a high metastatic potential. In cases of metastasis, approximately two-thirds of patients have lymph-node metastases and one-third develop systemic metastases. However, few studies have been reported that analyzed different metastatic patterns accord...

Choroidal melanoma is the most common primary intraocular cancer in adults. Metastases are most commonly found in the liver and are rapidly fatal despite aggressive therapy. These metastases have been reported in the follow-up to 50 % of uveal melanoma. However, recent reports have shown that liver ultrasonography and liver function tests have low sensitivity in the diagnosis of metastatic uvea...

UNLABELLED It is highly desired to develop new imaging probes for early detection of melanoma as early diagnosis and prompt surgical removal are a patient's best hope for a cure. The purpose of this study was to determine whether (99m)Tc- and (111)In-labeled alpha-melanocyte-stimulating hormone (alpha-MSH) peptides could be used as imaging probes for primary and metastatic melanoma using dual-m...

OBJECTIVE Adrenal masses usually represent benign and nonfunctional adrenal adenomas; however, primary or metastatic malignancy should also be considered. Discovery of an adrenal mass needs further evaluation in order to exclude malignancy and hormonal secretion. We present a rare case of a possibly primary adrenal malignant melanoma with imaging and biochemical features of a pheochromocytoma. ...

UNLABELLED Espin is a multifunctional actin-bundling protein with multiple isoforms, and has special connections to hair cell stereocilia and microvillar specializations of sensory cells in the inner ear. However, there have been no reports showing the expression and function of Espin in cancers, including melanoma. Here, it is demonstrated that Espin expression is significantly increased in me...

PURPOSE To identify genes that modify metastatic risk in uveal melanoma, a type of cancer that is valuable for studying metastasis because of its remarkably consistent metastatic pattern and well-characterized gene expression signature associated with metastasis. EXPERIMENTAL DESIGN We analyzed 53 primary uveal melanomas by gene expression profiling, array-based comparative genomic hybridizat...

The UDP-glucuronosyltransferase (UGT) family of enzymes plays a vital role in the detoxification of carcinogens as well as clearance of anti-cancer drugs. In humans, 19 UGT family members have been identified and are expressed in a tissue specific manner throughout the body. However, the UGTs have not been previously characterized in melanocytes or melanoma. In the present study, UGT2B7, UGT2B1...

background: the sentinel lymph node (sln) is defined as the first chain node in the lymphatic basin that receives primary lymphatic flow. if the sln is negative for metastatic disease, then other nodes are expected to be disease-free. sln techniques have been extensively applied in the staging and treatment of many tumors, including melanoma, breast and vulvar cancers. this study aims to evalua...
