[ 1 ] - Acute Myeloid Leukemia as the Main Cause of Pancytopenia in Iranian Population
Background & objective: Pancytopenia is the reduction in the number of all 3 major cellular elements of blood and leads to anemia, leukopenia, and thrombocytopenia. A wide variety of etiologies result in pancytopenia including leukemia, aplastic anemia, and megaloblastic anemia. The current study identified the different etiologies of pancytopenia base...
[ 2 ] - Study of Multiple Myeloma Occurrence in Patients With 5%-10% Bone Marrow Plasma Cells: A Case Series Regarding Revised IMWG Diagnostic Criteria
Introduction: Utilizing lower limit of bone marrow plasma cells (BMPCs) is the main existing criterion for diagnosis of multiple myeloma (MM). According to the revised international myeloma working group (IMWG) diagnostic criteria, the value of 10% is agreed among experts as the cutoff level for diagnosis. Symptomatic patients with BMPC above this value are identified as definite cases of MM. H...
[ 3 ] - A Tentative Staging of Multiple Myeloma by Utilizing Respective Coefficients of Prognostic Factors
Introduction: Multiple myeloma is a heterogeneous disease with different survival times among patients. Accurate prediction of prognosis in multiple myeloma is essential, as patients with a shorter survival time may require early bone marrow transplantation (BMT) and more advanced chemotherapy as a part of their first-line treatment. In the present study, a parameter, depicted by ga...
[ 4 ] - Role of Suppressed Immunoglobulins in Outcome of Patients With Multiple Myeloma
Introduction: Multiple myeloma (MM) is typically presented with abundant monoclonal secretion of one type of immunoglobulin. The other classes of immunoglobulins, which are uninvolved and not secreted by malignant plasma cells, could be decreased. A number of previous studies reported the effect of suppression of uninvolved immunoglobulins on the outcome of patients with myeloma. However, its e...
[ 5 ] - A Case Report of a Metastatic Primary Gastric Lymphoma; Diffuse Large B-Cell or Burkitt Lymphoma?
Introduction: Primary gastric lymphoma (PGL) is a rare tumor, whose differential diagnosis may become complicated without precise immunohistochemistry (IHC) and genetic analysis. Case Presentation: A 33-year-old woman presented with gastric cancer and had undergone gastrectomy without precise IHC and staging in another center. Inappropriate IHC after surgery showed diffuse large B-cell lymphom...
