We conducted a surveillance epidemiology and end results (SEER)-based analysis to describe the incidence and characteristics of second primary acute lymphoblastic leukemia (sALL) among adults (≥18 years) with a history of primary malignancies (1M). Standardized incidence ratios (SIRs) of sALL cases were calculated by site and 1M stage. We also evaluated the differences in 5-year sALL survival b...

ABSTRACT Secondary acute lymphoblastic leukaemia (sALL), defined as acute lymphoblastic leukaemia following another malignancy, irrespective of previous treatment, is a rare disease, and its biological characteristics have not been accurately described. We report the case of a 24-year old patient followed for Hodgkin's lymphoma at our clinic, who develops and is diagnosed, less than a year afte...

BACKGROUND Secondary acute lymphoblastic leukemia (sALL) is a rare disease and its biologic features are not well characterized. PATIENTS AND METHODS We describe a cohort of seven patients and discuss 94 additional cases from the literature for whom biological parameters were described. Cases with incomplete data were excluded. RESULTS Hodgkin's disease (HD) was more common in the 18-59 age...

The SALL (Spalt-like) family of zinc-finger transcription factors is conserved in metazoans. In Drosophila Sal (Spalt) and Salr (Spalt-related) control the expression of genes involved in wing and central nervous system development, including cell adhesion and cytoskeletal proteins. In humans, SALL mutations associate with congenital disorders such as the Townes-Brocks and Okihiro syndromes. Hu...

Secondary acute lymphoblastic leukemia (sALL) following acute myeloid leukemia (AML) is a rare event; only eight cases have been reported. We report a patient with acute promyelocytic leukemia (APL), in hematological and molecular remission who developed T-ALL three years after the diagnosis of APL. The morphological, cytochemical, phenotypical and molecular features of this T-ALL were differen...

BACKGROUND SALL4 is a member of the SALL gene family that encodes a group of putative developmental transcription factors. Murine Sall4 plays a critical role in maintaining embryonic stem cell (ES cell) pluripotency and self-renewal. We have shown that Sall4 activates Oct4 and is a master regulator in murine ES cells. Other SALL gene members, especially Sall1 and Sall3 are expressed in both mur...

The genetic mechanisms that regulate the complex morphogenesis of generating cartilage elements in correct positions with precise shapes during organogenesis, fundamental issues in developmental biology, are still not well understood. By focusing on the developing mouse limb, we confirm the importance of transcription factors encoded by the Sall gene family in proper limb morphogenesis, and fur...
