MicroRNAs (miRNAs) are short, endogenous RNA molecules that have essential roles in regulating gene expression. They control numerous physiological and cellular processes, including normal bone organogenesis and homeostasis, by enhancing or inhibiting bone marrow cell growth, differentiation, functional activity and crosstalk of the multiple cell types within the bone. Hence, elucidating miRNA ...
eighteen patients, twelve men and six women, with aplastic anemia underwent allogenic bone marrow transplantation (bmt) from hla-matched siblings during the period of 1990 to 1996. the conditioning regimen was cyclophosphamide with or without busulfan, depending on the cause of aplasia. antilymphocyte globulin (alg) and cyclosporine were used for rejection and acute gvhd prophylaxis, respective...
Introduction:The use of beta emitters is one of the effective methods for palliation of bone metastasis. The risk of normal tissue toxicity should be evaluated in the bone pain palliation treatment. Methods: In this study, the Monte Carlo simulation code MCNPX was used for simulation a bone phantom model consisted of bone marrow, bone and soft tissue. Spe...
PURPOSE Despite improvements in locoregional treatment of head and neck squamous cell carcinoma (HNSCC), local and distant failure rates remain high. The strongest prognostic indicator of HNSCC is the presence of lymph node metastases in the neck, but the value of this indicator has limitations when using for the individual patient. The presence of micrometastatic cells in bone marrow has been ...
In a subset of patients with early gastric cancer, there were recurrences of the disease after a curative resection had been done. Direct evidence of tumor seeding in distant organs at the time of surgery for gastric cancer is not available. An immunocytochemical assay for epithelial cytokeratin protein may fill this gap because it is a feature of epithelial cells that would not normally be pre...
Although bone marrow micrometastasis may remain silent, its detection changes the staging and management of lung cancer. In the present study conducted in West Bengal, India, 74 diagnosed bronchogenic carcinoma cases (28 squamous cell carcinomas, 20 adenocarcinomas, 9 small cell carcinomas, 4 large cell carcinomas, 13 unclassified) in early stages (stage I, II and IIIA) were included. Complete ...
Most of the prostate cancers (PCa) in advanced stage will progress to castration-resistant prostate cancer (CRPC). Within CRPC group, 50-70% of the patients will develop bone metastasis in axial and other regions of the skeleton. Once PCa cells spread to the bone, currently, no treatment regimens are available to eradicate the metastasis, and cancer-related death becomes inevitable. In 2012, it...
Primary splenic angiosarcomas are the most common malignant non-hematopoietic tumors of the spleen. Metastatic diseases were found in 69% of patients in a reported series but the incidence of bone marrow involvement is unclear. We report a rare case of a 25-years-old Moroccan woman with unsuspected primary splenic angiosarcoma revealed by bone marrow metastasis. She presented with serious anemi...
Bone metastasis greatly deteriorates the quality of life in patients with cancer. Although mechanisms have been widely investigated, the relationship between cancer bone metastasis and antitumor immunity in the host has been much less studied. Here, we report a novel mechanism of bone metastasis mediated by FSTL1, a follistatin-like glycoprotein secreted by Snail(+) tumor cells, which metastasi...
