Concurrent chemoradiotherapy is one of the main treatments for rectal cancer. Bone marrow suppression is one of the critical factors that affect the progress of radiotherapy. We aimed to explore the association of incidence of acute bone marrow suppression with dose-volume parameters of pelvic bone marrow among rectal cancer patients with concurrent chemoradiotherapy. We retrospectively analyze...

sunitinib is an oral tyrosine kinase inhibitor which prevents tumor growth and metastatic progression. it was approved for treatment of advanced renal cell cancer, gastrointestinal stromal tumor and advanced pancreatic neuroendocrine tumors. it has several adverse reactions on multi organ systems including hematologic system. although the neutropenia and thrombocytopenia commonly happens as gra...

We have investigated interferon as a mediator of hematopoietic suppression in bone marrow failure. Interferon production by stimulated peripheral blood mononuclear cells from patients with aplastic anemia was significantly higher than that observed in controls; spontaneous interferon production by these cells was also high for more than half of aplastic anemia patients. Circulating interferon, ...

T H E R E C O o N I T ! O N of ampicillin-resistant Hemophilus influenzae ~ has increased the use of chloramphenicol, particularly in management of invasive infections caused by this bacterium. Bone marrow toxicity, however, is a serious hazard. Based primarily on clinical data, two different bone marrow toxicities have been proposed. Reversible bone marrow suppression is frequent and dose rela...

The pathogenesis of the anemia associated with malignancy was investigated in a patient with T cell chronic lymphocytic leukemia. The plasma clot culture system was used as a measure in vitro of erythropoiesis. The patient's peripheral blood and marrow T lymphocytes obtained both before and after transfusion therapy suppressed erythroid colony formation by normal human bone marrow cells. Pretre...

Background: Bone marrow is the site of many malignant disorders and it is one of the common places for solid tumors to metastasize. Examination of the bone marrow aspirate and biopsy is a routine procedure performed for assessment of various conditions such as cytopenias, hematologic neoplasms, nonmalignant disorders and metastatic neoplasms. Methods: The patients were referred to the Hema...

A seventeen-year-old Jehovah’s witness with metastatic Ewing sarcoma initially declined cancer therapy due to the risk of life-threatening bone marrow suppression. He then subsequently agreed other treatment options bloodless supportive care measures in order achieve quality life and long-term control his disease. This case report adds collective knowledge providing including for patients cancer.
