Identification of a Cryptic t(8;20;21)(q22;p13;q22) Resulting in RUNX1T1/RUNX1 Fusion in a Patient with Newly Diagnosed Acute Myeloid Leukemia.

The detection of recurrent genetic abnormalities in acute myeloid leukemia (AML), including RUNX1T1/RUNX1 gene fusion, is critical for optimal medical management. Herein, we report a 45 year old woman with newly diagnosed AML and conventional chromosome studies that revealed an apparently balanced t(8;20)(q22;p13) in all 20 metaphases analyzed. A RUNX1T1/RUNX1 dual-color dual-fusion fluorescence in situ hybridization (FISH) probe set was subsequently performed and revealed a RUNX1T1/RUNX1 gene fusion.

Favorable outcomes of acute leukemias of ambiguous lineage treated with hyperCVAD: a multi-center retrospective study.

Acute leukemias of ambiguous lineage (ALAL) are rare hematologic malignancies with poor outcomes. Retrospective studies have suggested that acute lymphoblastic leukemia (ALL) regimens are more effective than acute myeloid leukemia (AML) regimens. We retrospectively examined the effectiveness of the widely-used adult ALL regimen hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (hyperCVAD) as initial therapy in patients with ALAL at five academic institutions.

Phase I Study of Sorafenib and Vorinostat in Advanced Hepatocellular Carcinoma.

Objectives: Preclinical data suggest histone deacetylase inhibitors improve the therapeutic index of sorafenib. A phase I study was initiated to establish the recommended phase 2 dose of sorafenib combined with vorinostat in patients with unresectable hepatocellular carcinoma.

Materials And Methods: Patients received vorinostat (200 to 400 mg by mouth once daily, 5 of 7 d) and sorafenib at standard or reduced doses (400 mg [cohort A] or 200 mg [cohort B] by mouth twice daily).

MDM2 antagonists as a novel treatment option for acute myeloid leukemia: perspectives on the therapeutic potential of idasanutlin (RG7388).

Acute myeloid leukemia (AML) is a clonal heterogenous malignancy of the myeloid cells with a poor prognosis lending itself to novel treatment strategies. TP53 is a critical tumor suppressor and plays an essential role in leukemogenesis. Although TP53 is relatively unusual in de novo AML, inactivation of wild-type p53 (WT-p53) is a common event.

Phase I study of pemetrexed with sorafenib in advanced solid tumors.

Purpose: To determine if combination treatment with pemetrexed and sorafenib is safe and tolerable in patients with advanced solid tumors.

Results: Thirty-seven patients were enrolled and 36 patients were treated (24 in cohort A; 12 in cohort B). The cohort A dose schedule resulted in problematic cumulative toxicity, while the cohort B dose schedule was found to be more tolerable.
