The Joint Research Centre of the European Commission (JRC), in partnership with 30 institutions, has produced a global land cover map for the year 2000, the GLC 2000 map. The validation of the GLC2000 product has now been completed. The accuracy assessment relied on two methods: a confidence-building method (quality control based on a comparison with(More)
Primary adenocarcinoma of the small bowel is a rare malignancy and is associated with poor survival outcome. Patient, tumor and treatment-related factors were analyzed for their association with recurrence and survival. Between 1971 and 2005, 64 patients with primary adenocarcinoma of the small bowel were treated at our institution. Clinico-pathologic data,(More)
Background: Gastrointestinal (GI) metastasis from melanoma has a dismal prognosis with few long-term survivors. We evaluated the role of operative intervention for melanoma metastases to the GI tract and attempted to identify prognostic factors to improve selection of patients for surgery. Methods: Between 1977 and 1997, 68 of the 7965 patients with(More)
OBJECTIVE An evidence-based review to ascertain the operative strategy for oncologic resection of malignant tumors of the liver and an optimal postoperative outcome. BACKGROUND Recommendations for resection of malignant tumors of the liver based on traditional considerations of locoregional control and survival benefit are modified by the functional(More)
Mutations in transporters associated with antigen processing (TAP-1 and -2) required for the transport of cytosolic endogenous peptides to the endoplasmic reticulum correlate with increased metastatic potential and reduced host survival in several malignancies. To address the possible function of TAP as a "tumor suppressor" gene, we show that correction of(More)
Despite potentially curative surgery pancreatic cancer has a dismal prognosis. Serum cancer antigen 19-9 (CA 19-9) correlates with tumor burden, resectability and survival in patients with pancreatic ductal adenocarcinoma. Identification of novel biomarkers may facilitate early diagnosis of pancreatic cancer and improve survival. Pancreatic juice is a rich(More)
We report an instructive case of extraskeletal osteosarcoma in a 63-year-old African American male who presented after an episode of recent trauma, with clinical and radiological features characteristic of this neoplasm. Osteosarcoma is the most common primary malignant tumor of bone in young adults, but the extraskeletal variety is very uncommon. The(More)
OBJECTIVE A review of the literature to identify current modalities for the diagnosis of autoimmune pancreatitis (AIP) with the objective of establishing a strategy to distinguish it from pancreaticobiliary cancers. BACKGROUND Pancreatic and biliary manifestations of AIP mimic pancreaticobiliary cancers. Misdiagnosis of AIP can result in major surgery for(More)
