Changes in DNA methylation of crucial cancer genes including tumor suppressors can occur early in carcinogenesis, being potentially important early indicators of cancer. The objective of this study was to examine a multiplexed approach to assess the methylation of tumor suppressor genes as tumor stratification and clinical outcome prognostic biomarkers for(More)
To evaluate the utility of nude mouse xenografts as preclinical drug screens, the activity of ten established chemotherapeutic agents was evaluated against seven melanoma and three ovarian carcinoma xenografts. Xenografts were established using primary explants from patients who had not received chemotherapy and serially passaged as sc tumors in nude mice.(More)
We report results of allogeneic bone marrow transplantation in an 8-year-old boy with acute megakaryoblastic leukemia characterized by intense fibrosis together with 20% blast cells in the bone marrow, who was transplanted without preceding chemotherapy for remission induction. Conditioning comprised cytosine arabinoside, cyclophosphamide and total body(More)
Primary melanoma of the esophagus (PME) is an uncommon malignancy with less than 250 cases reported in the literature. Amelanotic PME is exceedingly rare and accounts for 10-25% of melanomas of the esophagus. A 59-year-old male with a history of mild dysphagia, heartburn, moderate anorexia and weight loss for 1 month is described. Barium swallow examination(More)
A 48-year-old woman underwent surgery for a lesion seen on ultrasound and interpreted as a uterine myoma. The surgery revealed multiple nodules that had seeded on the omentum, peritoneum, and ovaries. The macroscopic interpretation was either metastasis or tuberculosis. The biopsy showed noncaseating granulomas, and a diagnosis of peritoneal sarcoidosis was(More)
INTRODUCTION The tumor, node, metastasis (TNM) system has been recognized internationally as the standard for staging disease extension, but despite the improvements of the 1997/2002 international staging system, there may be marked differences in postoperative 5-year survival rates within each stage. There is controversy about the impact of tumor size(More)
Nine patients (seven men and two women) were studied while undergoing coronary artery bypass on cardiopulmonary bypass. Selective bronchial flow samples were obtained and analyzed for prostaglandin E2 levels, and the hemodynamic effects of this vasodilator were studied. Bronchial flow collection and measurements were performed during hypothermic(More)
Primary systemic amyloidosis with clinical and histopathologic features of giant cell arteritis has already been described. The association of multiple myeloma (with primary amyloidosis) and giant cell arteritis is also known. We present the first case in the literature of a patient with multiple myeloma and giant cell arteritis without systemic(More)
