PURPOSE HSP90 is a chaperone protein required for the stability of a variety of client proteins. 17-Demethoxygeldanamycin (17-AAG) is a natural product that binds to HSP90 and inhibits its activity, thereby inducing the degradation of these clients. In preclinical studies, HER2 is one of the most sensitive known client proteins of 17-AAG. On the basis of(More)
Author manuscripts have been peer reviewed and accepted for publication but have not yet been edited. HSP90 is a ubiquitous protein that is commonly overexpressed in cancer cells where it is required to promote the proper folding of several oncoproteins. Without its chaperoning presence, these proteins are ubiquitylated and degraded, hence inhibiting HSP90(More)
PURPOSE This phase I study examined whether a heat shock protein (Hsp) 90 inhibitor tanespimycin (17-AAG; KOS-953) could be administered safely in combination with trastuzumab at a dose that inhibits Hsp90 function in vivo in lymphocytes. PATIENTS AND METHODS Patients with an advanced solid tumor progressing during standard therapy were eligible. Patients(More)
Medulloblastomas (MBs) are the most common malignant brain tumor in children. The current therapeutic strategies are ineffective against the infiltrative and disseminative nature of MBs in about one-third of patients. Based on studies which have revealed the tumor-tropic characteristic of neural stem cells (NSCs), we used an immortalized neural stem cell(More)
OBJECTIVE The purpose of our study is to present the radiographic findings in a series of 16 patients with complications associated with intravesical bacille Calmette-Guérin (BCG) treatment of bladder cancer. CONCLUSION Intravesical BCG-related complications such as granulomatous disease may show imaging findings mimicking primary or metastatic tumors in(More)
PURPOSE We conducted a phase I dose-escalation study to define the maximum tolerated dose (MTD), pharmacokinetics (PK), and pharmacodynamics of alvespimycin (17-DMAG), a heat shock protein 90 (Hsp90) inhibitor, given in combination with trastuzumab. EXPERIMENTAL DESIGN Patients were treated with trastuzumab followed by intravenous alvespimycin on a weekly(More)
Glioblastoma is the most common and most aggressive malignant primary brain tumor in humans, accounting for 52 % of all functional tissue brain tumor cases and 20 % of all intracranial tumors. The typical treatment involves a combination of chemotherapy, radiation, and surgery, whereas it still achieves fairly poor patient survival. Ginsenoside Rh2 has been(More)
BACKGROUND Gemcitabine is active in several gynecologic malignancies including ovarian cancer, cervical cancer, and uterine leiomyosarcoma. It has been used in an off-label setting for the treatment of advanced endometrial cancer, despite lack of published data showing efficacy. We performed a retrospective study to determine the progression-free survival(More)
OBJECTIVE Ovarian vein thrombosis is associated with pregnancy and pelvic surgery. Postpartum ovarian vein thrombosis is associated with infection and a high morbidity rate and is treated with anticoagulant and intravenous antibiotic therapy. The natural history of such thrombotic events after debulking surgery for ovarian cancer has not been well(More)
Purpose. To assess if there is a significant difference in enhancement of high grade serous carcinoma of the ovary compared with other ovarian malignancies on clinically performed contrast enhanced MRI studies. Methods. In this institutional-review-board-approved study, two radiologists reviewed contrast enhanced MRI scans in 37 patients with ovarian(More)
