Introduction. The treatment outcome of adolescents and young adults with acute lymphoblastic leukemia is much poorer in contrast to pediatric patients. By changing the concept for patients who are leukemia, especially use regimens, significant improvement survival has been made (current 5-year rate goes up 70%). Contributing factors different outcomes between children leukemia. Beside differenc...

CONTEXT Despite the advances in the cure rate for acute lymphoblastic leukemia, approximately 25% of affected children suffer relapses. Expression of genes for the multiple drug resistance protein (MDR-1), multidrug resistance-related protein (MRP), and lung resistance protein (LRP) may confer the phenotype of resistance to the treatment of neoplasias. OBJECTIVE To analyze the expression of t...

Herein, we present a rare case of acute myeloid leukemia (AML) with CBFA2T3-rearrangement and the expression megakaryocytic lymphoid markers, highlighting need for high suspicion index in differential diagnosis applying adequate workup to avoid misdiagnosing this entity. CBFA2T3::GLIS2-positive AML is primarily found infants non-down syndrome megakaryoblastic (non-DSAMKL). Flow cytometry immuno...

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome of excessive immune activation, which is characterized by fever, hepatosplenomegaly, cytopenias, hyperferritinemia, hypertriglyceridemia, and/or hypofibrinogenemia, and evidence of hemophagocytosis. Secondary HLH is often seen in adults and categorized based on autoimmune, infections-related, and malignancy-associated etiol...

BACKGROUND Chemotherapy is the commonly accepted standard therapy for most types of brain tumor, especially in medulloblastoma, primitive neuroectodermal tumor and astrocytoma. However, no efficient therapy has been established to date for glioblastoma multiforme. The aim of the present study was to analyze the activity of bortezomib in glioblastoma cell lines in comparison with that in a pedia...

OBJECTIVE To determine whether clinical trial enrollment by itself is associated with improved outcome. DESIGN Retrospective cohort study. SETTING Seattle Children's Hospital from 1997 to 2005. PARTICIPANTS Data were drawn from 322 patients with newly diagnosed acute lymphoblastic leukemia. Main Exposure Enrollment in a Children's Oncology Group or Children's Cancer Group clinical trial. ...

Thyroid-like follicular carcinoma of the kidney (TLFCK) is a rare histological variant of renal cell carcinoma not currently included in the World Health Organization classification of renal tumors. Only 24 previous cases of TLFCK have been reported to date. We report a case of TLFCK in a 19-year-old woman with history of pediatric acute lymphoblastic leukemia. This patient is the youngest with...
