Abstract

Granulopoesis colony-stimulating factor filgrastim is used to mobilize peripheral stem cells but there are concerns regarding an elevated risk of haematological malignancies. We analyzed the incidence of malignancies and the system of haematopoietic stem cells donor surveillance. prospective observation of sibling donors of the Haemato-Oncology Department University Hospital in Plzen (Pilsen) and of unrelated donors of the Czech National Marrow Donors Registry (CNMDR) in 2001-2010. No malignancy was observed in a group of 344 unrelated CNMDR donors, providing 753 person-years; one case of chronic lymphocytic leukaemia manifested 6 years after bone marrow donation, with leukaemia clone retrospectively detected by DNA analysis in blood samples taken prior to the marrow donation. Acute myeloid leukaemia, non-Hodgkin lymphoma, renal and colorectal carcinoma were observed in a group of 84 peripheral stem cells sibling donors, providing 337 person-years observation. The respective incidence of the two haematologic malignancies was 593 cases and the expected incidence rate was 143 per 100,000. The sibling (related) donors age was significantly higher: 48 (16-75) vs. 31 (20-42) years, (p<0.0001). Significantly more lost-to-follow-up do...Continue Reading

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.
