Open AccessKOC is a novel molecular indicator of malignancy
The detection of malignant cells in fine-needle aspirates (FNA's) using marker genes is hampered by the fact that these markers are only expressed by certain malignancies or lack sensitivity and/or specificity...

Loss of heterozygosity on chromosome 6q14–q24 is associated with poor outcome in children and adolescents with T-cell lymphoblastic lymphoma
Deletions of chromosome 6q have been reported in several hematological malignancies, but data are not conclusive regarding their biological and prognostic impact. Therefore, we focused on pediatric patients di...
