Objectives. The B-cell-specific moloney leukemia virus insertion site 1 (the Bmi-1) gene is an important member in the family of polycomb group (PcG) genes that plays an oncogenic role in several types of cancer, but it's expression as a prognostic marker in pediatric brain tumors has not been indicated. Materials and Methods. The Bmi-1 gene expression, clinic pathological and prognostic signif...

the brain is a rare site for metastasis in most extracranial pediatric solid tumors, including wilm’s tumor. outcome for these patients are generally dismal. very few cases have been reported to have good survival even after therapy. this paper reports a case of stage iv wilm’s tumor with lung metastases in a patient who developed a solitary brain metastasis five months after completion of chem...

Brain tumors are the most common solid tumors in childhood. Glioblastoma multiform (GBM) is the second most common primary brain tumor in adults. It usually affects the cerebral hemispheres of adults at the 6th or 7th decade of life. In comparison to adult population, GBM is rare in pediatrics and accounts for approximately 3% of all pediatric brain tumors. Pediatric glioblastoma was defined as...

Primitive neuroectodermal tumors (PNET) of the brain include medulloblastoma (MB) and central nervous system primitive neuroectodermal tumor (CNS PNET) subtypes, which share histological features yet differ at the genomic level and in clinical outcome. Delineation of the genetic anomalies between PNET subtypes is a current challenge for establishing effective targeted therapeutic strategies aga...
