The International Society for the Study of Vascular Anomalies (ISSVA) classification is becoming the international standard classification system for vascular tumors and vascular malformations. The ISSVA classification strictly distinguishes vascular tumors (neoplastic lesions) from vascular malformations (non-neoplastic lesions) based on whether there is a(More)
RATIONALE AND OBJECTIVES We investigated the efficacy of prophylactic cement injection into the vertebral body adjacent to fractured vertebra to prevent new fractures after percutaneous vertebroplasty (PV). MATERIALS AND METHODS Between February 2002 to August 2004, PV was performed for osteoporotic compression fractures in 89 consecutive patients. All(More)
There is no data about the efficacy and safety of radioimmunotherapy with 90Y-ibritumomab tiuxetan in patients with relapsed or refractory indolent B-cell lymphoma pretreated with rituximab-containing chemotherapy. We focused on this in a Japanese phase II study. Radioimmunotherapy with 90Y-ibritumomab tiuxetan (11.1 and 14.8 MBq) was evaluated in patients(More)
Cis-Diamminedichloroplatinum (CDDP) — lipiodol suspension (CLS) was developed as a transarterial chemoembolization (TACE) material. The CLS was injected into the proper hepatic artery or distal branches of patients with hepatocellular carcinoma. Strong anticancer effects were observed. Plasma concentrations of total and filtrable CDDP following TACE were(More)
Oral fludarabine is more convenient than intravenous fludarabine in an outpatient setting. To assess the efficacy and toxicity of oral fludarabine in combination with rituximab in patients with relapsed indolent B-cell non-Hodgkin lymphoma (B-NHL), we conducted a multicenter phase II study. Patients with relapsed indolent B-NHL with two or fewer prior(More)
The aim of this study was to assess the potential diagnostic value of three-dimensional T2-weighted imaging using the dark blood method for detecting pulmonary embolism (PE). Ten consecutive patients with already diagnosed acute PE (five men, five women; mean age 58.6 years, range 35–79 years) were prospectively enrolled in this study. All patients(More)
PURPOSE The aim of this study was to assess the efficacy of radiofrequency ablation in the treatment of pelvic recurrent rectal cancer. METHODS Computed tomography-guided percutaneous radiofrequency ablation was performed by placing a LeVeen needle electrode into the tumor. Radiofrequency ablation was performed on three lesions in two patients with pelvic(More)
RATIONALE AND OBJECTIVES Filling intravertebral clefts during percutaneous vertebroplasty (PVP) is considered to be important for optimal pain control. It is often difficult to detect clefts on non-contrast MR and some fractures show a solid pattern distribution of injected cement without a cleft sign on non-contrast MR. In this study, we evaluated(More)
Percutaneous injection of bone cement is a promising treatment for metastatic tumors. We present a case of hemorrhagic sacral metastases from hepatocellular carcinoma treated successfully by percutaneous sacroplasty with combined injections of bone cement and n-butyl cyanoacrylate resulting in pain relief.
PURPOSE Although intravenous (IV) fludarabine phosphate is effective against indolent B-cell non-Hodgkin's lymphoma (B-NHL), IV administration for 3 to 5 consecutive days is inconvenient in an outpatient setting. To assess the efficacy and toxicity of oral fludarabine phosphate in patients with indolent B-NHL, we conducted a multicenter phase II study. (More)
