The epidermal growth factor receptor (EGFR) is a promising target for anticancer therapy because of its role in tumor growth, metastasis and angiogenesis, and tumor resistance to chemotherapy and radiotherapy. We have developed a low-molecular-weight EGFR tyrosine kinase inhibitor (EGFR-TKI), ZD1839 (Iressa(2) ). ZD1839, a substituted anilinoquinazoline, is(More)
PURPOSE The detection of melanoma cells in the circulation by polymerase chain reaction (PCR) assays has been shown by several investigators to correlate with the stage of the disease and possibly with prognosis. PATIENTS AND METHODS We performed prospective studies on 276 patients with primary melanoma and regional lymph node (LN) metastases to assess(More)
PURPOSE Polymerase chain reaction (PCR) with tyrosinase and with MART-1 permits detection of small numbers of circulating melanoma cells (CMCs) in patients who have undergone surgical resection of localized disease. In a previous study, we showed that PCR with MART-1 had sensitivity and specificity similar to those of PCR with tyrosinase in terms of(More)
A method for the quantitation of tyrosinase mRNA in the bloodstream of melanoma patients has been developed by using competitive polymerase chain reaction (PCR) with a heterologous DNA (PCR MIMIC) as an internal standard. The method was validated by demonstration of similar amplification efficiencies for both molecules and by accurate quantitation of an(More)
A 60-year-old man presented with progressive and unique neurological symptoms. Investigations identified an isolated cerebellar lesion. This lesion fulfilled the histological criteria for lymphomatoid granulomatosis, and in situ hybridization and deoxyribonucleic acid (DNA) dot blot techniques revealed significant amounts of Epstein-Barr virus DNA within(More)
We performed prospective serial studies on 266 melanoma patients undergoing surgery for high risk primary or lymph node metastases to assess the predictive value for recurrence of melanoma of S-100beta detection in the serum using immunoradiometric assay (IRMA) or Immunoluminometric assay (LIA-mat). The tests for S-100beta were most frequently positive in(More)
BACKGROUND Stroke caused by spontaneous thrombosis of an unruptured intracranial aneurysm is a rare event. CASE DESCRIPTION A 66-year-old woman experienced a transient ischemic attack and cerebral infarctions due to spontaneous thrombosis of an unruptured anterior communicating artery aneurysm. Extension of thrombus into both anterior cerebral arteries(More)
Cranial CT changes associated with metabolic and storage disorders have been well documented. However, until recently [1], CT findings in galactosemia had not been shown. Previous neuropathologic autopsy findings in galactosemia have been described by Crome [2] as a "microencephaly caused by a mainly burnt out gliotic encephalomyelopathy ." Hypothesized(More)
Neurenteric cysts are "rare benign mass forming developmental abnormalities" that usually affect young adults. Neurenteric cysts are thought to be derived from primitive endoderm, and form as a result of faulty endodermal-notochordal separation at 3 weeks of embryogenesis. Neurenteric cysts are lined by simple-to-pseudostratified(More)
A unique case of Huntington's disease is reported because of the extremely early onset and death, and the atypical mode of presentation including severe behavioural problems and a negative family history. Although rare, Huntington's disease must be considered along with the established degenerative disorders of white and gray matter peculiar to the(More)
