We studied the effect of arsenic trioxide (As2O3) on prostate and ovarian carcinoma cell lines. As2O3 has been shown to be effective in leukemia, and acute promyelocytic leukemia in particular, both in vitro and in vivo. As model cell lines, we used DU145 and PC-3 for prostate cancer and MDAH 2774 for ovarian cancer. New modalities of treatment are(More)
BACKGROUND The management of hormone-refractory prostate cancer (HRPC) still remains as an important challenge of daily oncology practice. Docetaxel has proved to be a first line treatment choice. All-trans retinoic acid (ATRA) could potently inhibit the growth of prostate cancer cells in vitro and its combination with various anticancer agents results in(More)
Prostate cancer (PCa) is the most common type of cancer among males. Although survival rate of early-stage PCa is high, treatment options are very limited for recurrent disease. In this study, the possible synergistic cytotoxic and apoptotic effect of octreotide in combination with AT-101 was investigated in DU-145 hormone and drug refractory prostate(More)
OBJECTIVE The aim of this study was to determine the markers of prognosis in metastatic inflammatory breast cancer (IBC). SUBJECTS AND METHODS The prognostic value of patients' clinical characteristics and expression of c-erbB-2, p53, Ki-67, ER and PgR were assessed in the 45 patients with IBC who had developed distant metastasis. Immunohistochemical(More)
BACKGROUND Ovarian cancer is the most fatal gynecologic malignancies in the world. Although, platinum based treatments are widely used, the disease becomes treatment refractory within two years, and novel treatment options should be searched. All- trans retinoic acid (ATRA) induces growth arrest, differentiation and cell death in some types of cancer cells(More)
PURPOSE Exposure to all active agents may be more important than specific sequence of drug administration in the treatment of patients with metastatic colorectal cancer (mCRC). The purpose of this study was to evaluate the overall survival (OS) of mCRC patients who were treated with all 5 major therapeutic agents used in this malignancy. METHODS We(More)
