lymphomas are solid tumors of immune system and non-hodgkin lymphomas (nhl) is the most prevalent lymphomas; with wide ranges of histological and clinical features, it is so difficult to identify them. herein, various bioinformatics tools (such as gene differential expressions, epigenetics and protein analysis) employed to find new treatment approach for nhl based on gene expression variation b...

introduction: a study was made conserning 142 patients who were suffering from gastrointestinal lymphoma, were seen at the department of hematology and oncology, esfahan medical school, during the period 1982-2002. method: all patients had laparotomy, and biopsy of the site lesion. histopathological subtypes were done in the international working formulation. stage groupings were done applying ...

Bone marrow macrophages containing other cells, or large pieces of other cells, represent a distinctive feature of diseases such as Hemophagocytic Lymphohistiocytosis (HLH) and Rosai-Dorfman disease. We describe a distinct variation of phagocytic histiocyte morphology, featuring histiocytes containing predominantly fragments of neutrophil nuclei. We retrospectively reviewed initial bone marrow ...

Survival of patients with multiple myeloma has improved substantially because of availability of new therapies including autotransplants, immunomodulating drugs and proteasome-inhibitors. Second primary cancers have emerged as an important determinant of morbidity and mortality among cancer survivors. Even though there is an increased risk of new cancers of the lymphoreticular and haematopoetic...

Several studies have suggested an increased risk of lymphoma among workers exposed to meat, without conclusive evidence. We conducted a multicenter case-control study during 1998-2004 in the Czech Republic, France, Germany, Ireland, Italy and Spain, including 2,007 cases of non-Hodgkin lymphoma, 339 cases of Hodgkin lymphoma and 2,462 controls. We collected detailed information on occupational ...

BACKGROUND Hodgkin lymphoma is one of the most prevalent lymphoproliferative disorders in Pakistan; however, no risk factors for this disease have yet to be established in our population. Epstein-Barr virus (EBV) is a well-known risk factor for Hodgkin lymphoma in endemic regions of the world; however, frequency of its association in our population has not been widely studied. Latent membrane p...

The FOXO transcription factors control proliferation and apoptosis in different cell types. Their activity is regulated by posttranslational modifications, mainly by the PI3K-PKB pathway, which controls nuclear export and degradation. We show that FOXO1 is highly expressed in normal germinal center B cells as well as in non-Hodgkin lymphomas, including follicular lymphoma, diffuse large B-cell ...

burkitt's lymphoma is a lymphatic tumor classified as non-hodgkin lymphoma with small non cleaved cells. the disease has an incidence of two cases per million patients in north america, and usually present with an intra-abdominal tumor, or enlarged cervical lymph nodes. massive amounts of peritoneal and plural fluid is rarely seen in these patients. a three year-old girl presented with massive ...

Expression of prolactin and of prolactin and estrogen receptors in lymphocytes, bone marrow, and lymphoma cell lines suggests that hormonal modulation may influence lymphoma risk. Prolactin and estrogen promote the proliferation and survival of B cells, factors that may increase non-Hodgkin lymphoma risk, and effects of estrogen may be modified by catechol-O-methyltransferase (COMT), an enzyme ...
