Osteoradionecrosis (ORN) of the pelvic bone presenting as a progressive osteolytic lesion, following three-dimensional conformal radiotherapy (3DCRT) with concurrent chemotherapy, is a clinical diagnostic challenge that must be differentiated from an osseous metastasis. We report on a case with an unusual presentation of ORN mimicking bony metastasis that(More)
PURPOSE This study was performed to evaluate the treatment results, prognostic factors and complication rates in patients with locally advanced cancer of uterine cervix after radiotherapy with high-dose rate (HDR) brachytherapy. MATERIALS AND METHODS One hundred and twenty patients with a locally advanced (stages IIB approximately IVA according to FIGO(More)
PURPOSE We sought to investigate the efficacy of in vitro extreme drug resistance (EDR) assay for the prediction of drug response, platinum-resistance (progression-free survival, PFS <6 months) and survival in patients with epithelial ovarian cancer (EOC) who received taxane- and platinum-based chemotherapy after surgery. METHODS Between December 2005 and(More)
OBJECTIVE The purpose of this study was to determine the prognostic significance of tumor volume regression rate during radiotherapy (RT) measured by three serial magnetic resonance imaging (MRIs) studies performed in patients treated with RT alone and compare the results with patients treated with concurrent chemoradiotherapy (CCRT). METHODS We evaluated(More)
OBJECTIVE The purpose of this study is to elucidate the usefulness of magnetic resonance imaging (MRI) and positron emission tomography (PET) for the detection of parametrial involvement and lymph node metastasis in patients with cervical cancer. METHODS Thirty-six patients with cervical cancer were retrospectively enrolled. MRI and PET scans were(More)
BACKGROUND Magnetic resonance imaging (MRI) has been frequently used to determine a preoperative treatment plan for gynecologic cancers. However, the MR accuracy for staging an endometrial cancer is not satisfactory based on the old FIGO staging system. PURPOSE To evaluate MR accuracy for staging endometrial cancer using the new FIGO staging system. (More)
We have previously reported that central repeated units (CRUs) of Ahnak act as a scaffolding protein networking phospholipase Cgamma and protein kinase C (PKC). Here, we demonstrate that an Ahnak derivative consisting of four central repeated units binds and activates PKC-alpha in a phosphatidylserine/1,2-dioleoyl-sn-glycerol-independent manner. Moreover,(More)
PURPOSE The aim of this phase II study was to investigate the efficacy and toxicity of combined ifosfamide and cisplatin chemotherapy in patients with recurrent epithelial ovarian cancer (EOC). EXPERIMENTAL DESIGN Forty-seven patients with recurrent EOC were treated with ifosfamide 5 g/m(2) and cisplatin 50 mg/m(2) on day 1, every 3 weeks for 6 cycles.(More)
Although mutations in the insulin receptor have been causally implicated with leprechaunism, the full pathophysiology of the syndrome cannot be accounted for by malfunction of this gene alone. We sought to characterize a connection between Wnt-mediated cell signaling and the production of reactive oxygen species (ROS) which revealed a novel mechanistic(More)
OBJECTIVE To evaluate the clinicopathologic characteristics and prognostic factors of ovarian granulosa cell tumors. METHODS Medical records of 113 patients presenting between January 1995 and December 2007 were retrospectively reviewed. RESULTS One-hundred two patients had adult type disease, with a mean age of 46.2 years (range, 18 to 83 years) and a(More)
