Results of the Phase I Trial of RG7112, a Small-Molecule MDM2 Antagonist in Leukemia.

Purpose: RG7112 is a small-molecule MDM2 antagonist. MDM2 is a negative regulator of the tumor suppressor p53 and frequently overexpressed in leukemias. Thus, a phase I study of RG7112 in patients with hematologic malignancies was conducted.

Interferon-induced protein with tetratricopeptide repeats 1 (IFIT1) as a prognostic marker for local control in T1-2 N0 breast cancer treated with breast-conserving surgery and radiation therapy (BCS + RT).

Interferon-induced protein with tetratricopeptide repeats 1 (IFIT1) expression, involved in the regulation of translation, has been implicated to mediate resistance to chemotherapy and radiation in cancer cells in vitro. The purpose of this study was to evaluate the prognostic significance of IFIT1 protein expression in patients with breast cancer treated with Breast-Conserving Surgery and Radiation Therapy (BCS + RT). A tissue microarray was constructed with specimens from 282 women with node-negative, early-stage (I/II) breast cancer who were treated with BCS + RT.

Intensity-modulated radiation therapy for orbital lymphoma.

Purpose: Orbital manifestations of non-Hodgkin's lymphoma (NHL) are rare and accounts for only 1% of all cases of NHL. There have been no reports of treating orbital lymphoma using intensity-modulated radiotherapy (IMRT).

Materials And Methods: Four patients were treated at our institution for orbital lymphoma using IMRT.

The individualization of cancer therapy: the unexpected role of p53.

Our laboratory discovered that p53 can regulate the sensitivity to cancer therapies by affecting three critical aspects of cancer pharmacology: 1). The expression of drug targets; 2). the access of drugs to intracellular targets; and the response to DNA damage.
