Although treatment results for adult acute lymphoblastic leukemia (ALL) have improved considerably in the past decades, treating adult patients with relapsed/refractory acute lymphocytic leukemia (ALL) is still difficult. Adults with refractory/relapsed acute lymphocytic leukemia (ALL) processed to death rapidly associated with chemotherapy resistance, high mortality by reinduction, etc. Only 2...

nitric oxide (no) is a molecule required for many physiological functions, produced from l-arginine by no synthases (nos). it is a free radical, producing many reactive intermediates that account for its bioactivity. sustained induction of the inducible form of nos (inos) in chronic inflammation may be mutagenic, through no-mediated dna damage or hindrance to dna repair, and thus potentially ca...

A cancer diagnosis is one of the most difficult medical challenges. Leukemia a type that affects bone marrow and/or blood and accounts for approximately 8% all cancers. Understanding epidemiology trends leukemia critical planning. Specialists diagnose using morphological analysis, but there possibility error in diagnosis. Since so to diagnose, intelligent methods are required. The primary goal ...

We investigated the frequency of mutations activating RAS oncogenes in human lymphoid malignancies, including B- and T-cell-derived acute lymphoblastic leukemia, chronic lymphocytic leukemia, and non-Hodgkin lymphoma. By the polymerase chain reaction/oligonucleotide hybridization method, DNA from 178 cases was analyzed for activating mutations involving codons 12 and 61 of the HRAS, KRAS and NR...

OBJECTIVE To detect markers for minimal residual disease monitoring based on conventional polymerase chain reaction for immunoglobulin, T-cell receptor rearrangements and the Sil-Tal1 deletion in patients with acute lymphocytic leukemia. METHODS Fifty-nine children with acute lymphocytic leukemia from three institutions in Minas Gerais, Brazil, were prospectively studied. Clonal rearrangement...


 Acute Lymphocytic leukemia (ALL) is the most common childhood malignancy, CNS involvement occurs in 3-5% of patients. We present a case 14-year-old boy who presented to us with nighttime fever, headache, and right-sided focal fits. Reports showed decreased platelets, increased WBC predominant eosinophils imaging subgaleal, epidural subdural collection. Bone marrow biopsy CSF analysis wer...
