t is estimated that the human T lymphotropic virus type (HTLV-1) infects approximately 20 million people worldide. Associated diseases, however, manifest only in 5–10% f infected individuals.1 Studies have shown that HTLV-1 is ndemic in Southern Japan, the Caribbean, South America, elanesian islands, Papua New Guinea, the Middle East and entral and Southern Africa. In Brazil, HTLV-1 infection i...

abstract background: abdominal tumors are still a diagnostic problem in children. this study was conducted to assess the presentation and types of childhood intra abdominal tumors in children in shiraz. materials and methods: participants of this historical cohort study consisted of 298 children aged between 1.5 months to 15 years old who were diagnosed with abdominal mass between march 2003 an...

Multiple myeloma (MM) is a malignant plasma cell neoplasm that accounts for slightly more than 10% of all hematologic cancers and remains incurable. The major challenge remains the identification of better diagnosis and prognostic biomarkers. The advent of proteomic technologies creates new opportunities and challenges for those seeking to gain greater understanding of MM. Although there is a l...

The molecular events that allow for clonal expansion of the malignant population in chronic myelogenous leukemia (CML) are poorly understood. Recent experiments in transgenic mice suggest a close temporal relationship between expression of the aberrant protein and manifestation of a hematologic neoplasm that resembles CML; tracing the same phenomenon in humans has not been possible. We studied ...

Various chemotherapy schemes have been evaluated in SMZL. These include: chlorambucil alone, cyclophosphamide, vincristine and prednisone (CVP), or the same plus doxorrubicin (CHOP). All the mentioned schemes have limited efficacy in SMZL. The limited number of patients in these studies, as well as the selection bias (patients with advanced pathology and worse prognosis are those who undergo ch...

Chromosomal in situ suppression (CISS) hybridization was performed with library DNA from sorted human chromosomes 8, 9, 15, 17, 21, and 22 on immunologically stained bone marrow cells of four patients with a hematologic neoplasm, including two patients with myelodysplastic syndrome and trisomy 8, one patient with promyelocytic leukemia bearing the translocation t(15;17)(q22;q11-12), and one pat...

background: clinical and epidemiological variation was seen between the colon cancer (cc) and rectum cancer (rc). so, there is not so much data available about the epidemiological and clinicopathological differences and prognostic factors regarding to cc and cr in iran, we aimed to perform this study. methods: all cases of cc and rc referred to oncology and gastroenterology wards of taleghani g...

In systemic mastocytosis (SM), the clinical features and survival vary greatly. Patient-related factors determining outcome in SM are largely unknown. Methods: We examined impact of sex on features, progression-free (PFS), overall (OS) 3403 patients with collected registry European Competence Network Mastocytosis (ECNM). The cytogenetic molecular genetic aberrations differences was analyzed a s...

introduction: most of the hematologic malignancies are heterogenous with regard to morphology, immunophenotype, and genetic rearrangements. multiple recurrent chromosomal aberrations have been identified by conventional cytogenetic analysis, which is now widely recognized as one of the most important diagnostic and prognostic determinants in these patients. patients and methods: bone marrow sam...
