The objective of this study was to evaluate whether longitudinal levels of serum YKL-40 correlate with disease status or survival in adults with gliomas. Patients with histologically confirmed gliomas were eligible for this longitudinal study. Serum samples were collected prospectively and concurrently with MRI scans at multiple time points during the course of the disease. YKL-40 levels determ...
BACKGROUND AND PURPOSE The association of high-grade oligodendrogliomas with tumor contrast material enhancement on MR images has been reported. Some authors have even used contrast enhancement as a criterion for their oligodendroglioma grading system. The purpose of our study was to evaluate if tumor contrast enhancement is a specific finding for anaplastic oligodendroglioma. METHODS Pretrea...
Current chemotherapy with doxorubicin fails to eradicate anaplastic thyroid cancer or even to stop tumor progress which may be due to the failure of these drugs to effectively target putative cancer stem cells. To test this hypothesis, anaplastic thyroid cell lines were characterized by FACS for their content of cancer stem cells, their in vitro sphere-forming capacity and their expression of m...
A characteristic feature of anaplastic large cell lymphoma is the significant repression of the T-cell expression program despite its T-cell origin. The reasons for this down-regulation of T-cell phenotype are still unknown. To elucidate whether epigenetic mechanisms are responsible for the loss of the T-cell phenotype, we treated anaplastic large cell lymphoma and T-cell lymphoma/leukemia cell...
neuroblastoma is the most common extracranial solid tumor in childhood. in different classification of neuroblastomas, a subset of undifferentiated or poorly differentiated tumors with bizarre histological features has been mentioned. a 3-year-old girl presented with abdominal pain. her haematological and biochemical parameters were normal except her urinary vanelylmandelic acid level was elevat...
INTRODUCTION Most primary stomach lymphomas are now recognized to originate from B-cell. Primary gastric anaplastic lymphoma kinase (ALK)-negative anaplastic large-cell lymphoma (ALCL) as shown in this case is very rare. CASE REPORT A 59-year-old man presented with a 1-month history of epigastric pain. Computed tomography showed a tumor in the stomach with perigastric lymphadenopathy. Biopsy ...
