[Correlation of single-cell gel electrophoresis and mitomycin C-induced chromosomal breakage for chromosomal instabiligy in children with Fanconi anemia].

Objective: Fanconi anemia (FA) is characterized by bone marrow failure, congenital abnormalities and predisposition to neoplasia. Hypersensitivity of FA cells to the clastogenic effect of mitomycin C (MMC) provides a unique marker for the diagnosis before the beginning of hematological manifestations. The aim of this study was to evaluate the relationship between Single-Cell Gel Electrophoresis (SCGE) and mitomycin C-induced chromosomal breakage in children with FA.

[Role of IFN-γ + 874 genetic polymorphisms in allogeneic hematopoietic stem cell transplantation].

Objective: To explore the impact of IFN-γ + 874 polymorphisms on the outcome in HLA matched sibling HSCT.

Methods: We used PCR-sequence-specific primer analysis (PCR-SSP) to analyze the polymorphisms of IFN-γ + 874 T/A in 80 recipient and donor pairs from October 2005 to March 2008.

Results: Recipients having donors who possessed IFN-γ + 874 A/A genotype had significantly earlier neutrophil recovery compared with those having donors with non-A/A genotype (15 (11 - 27) days vs 18 (12 - 30) days, P = 0.

[A new prognostic stratification for patients with acute myeloid leukemia].

Objective: To evaluate the impact of the percentage of residual blasts in bone marrow at the end of induction chemotherapy (T1) or during myelosuppression phase (T2) on prognosis of de novo acute myeloid leukemia (AML) (non M(3)) in 105 cases. To refine AML risk-stratification by combining the percentage of residual blast cells (T1 or/and T2) with cytogenetic data based the South West Oncology Group (SWOG) criteria.

Methods: The data of 105 de novo AML (non M(3)) patients hospitalized between January 1st 1999 and February 1st 2008 were retrospectively reviewed.
