Effect of single-unit transfusion in patients treated for haematological disease including acute leukemia: A multicenter randomized controlled clinical trial.

Background: Retrospective studies in hematological unit have suggested that single red blood cell (1-RBC) unit transfusion policy may reduce the number of RBC used without negative clinical impact.

Method: Acute leukemia patients requiring intensive chemotherapy or patients receiving autologous or allogeneic transplantation were randomly assigned to receive either single RBC (1-RBC arm) or double RBC (2-RBC arm) per transfusion with a hemoglobin trigger of 8 g/dL. The primary composite endpoint was the percentage of patients experiencing serious complications, such as a non-hematological adverse event grade ≥ 3 or intensive care admission or death.

[The French mesothelioma network from 1998 to 2013].

Mesothelioma is a rare disease less than 0.3% of cancers in France, very aggressive and resistant to the majority of conventional therapies. Asbestos exposure is nearly the only recognized cause of mesothelioma in men observed in 80% of case.

Status of RASSF1A in uveal melanocytes and melanoma cells.

RASSF1A gene, found at the 3p21.3 locus, is a tumor suppressor gene frequently hypermethylated in human cancers. In this study, we report that compared with melanocytes in normal choroid, RASSF1A is downregulated in uveal melanoma samples and in uveal melanoma cell lines.
