PURPOSE This study investigated sequential changes in tumor blood supply using magnetic resonance (MR) perfusion imaging and assessed their significance in the prediction of outcome of patients with advanced cervical cancer. The purpose of this project was to devise a simple, noninvasive method to predict early signs of treatment failure in advanced(More)
Twenty patients with biopsy-proven ependymomas of the spinal cord were treated between 1960 and 1984-7 with surgery only, 3 with radiation therapy only, and 10 with surgery and postoperative radiation therapy. Of these, 2 patients developed recurrent tumor at the primary site, 3 developed a recurrent tumor in the thecal sac, and 1 developed distant(More)
Between 1960 and 1985, 30 patients with solitary plasmacytomas were treated with radiotherapy at the University of Iowa: 13 patients with extramedullary plasmacytomas (EMP) and 17 with solitary plasmacytomas of bone (SPB). The local control rates were 92% for patients with EMP and 88% for those with SPB. Two of nine patients (22%) with EMP treated to the(More)
PURPOSE To determine if radiation therapy treatment duration has an impact on the outcome of intracranial ependymoma. METHODS AND MATERIALS From 1965 to 1997, 34 patients with intracranial ependymoma were seen and treated with postoperative radiotherapy (RT). There were 26 male and 8 female patients with a median age of 14 years (range, 18 months to 60(More)
PURPOSE Clinical evaluation of tumor size in cervical cancer is often difficult, and clinical signs of radiation therapy failure may not be present until well after completion of treatment. The purpose of this study is to investigate early indicators of treatment response using magnetic resonance (MR) imaging for quantitative assessment of tumor volume and(More)
Between 1955 and 1987, 15 patients with hemangiopericytomas were seen at the University of Iowa Hospitals and Clinics. Twelve of these were thought to have localized tumors and three had metastatic disease at diagnosis. Seven of the 12 patients with localized disease were treated with surgery alone, four were treated with surgery and postoperative radiation(More)
PURPOSE To examine the long-term effects of treatment in children receiving radiotherapy for head and neck rhabdomyosarcoma. METHODS From 1967 to 1994, a total of 30 children with head and neck rhabdomyosarcoma received megavoltage radiotherapy at one institution. Seventeen patients (57%) have survived and have at least a 5-year follow-up. There were 11(More)
Between January 1950 and December 1981, 32 patients with chemodectomas of the temporal bone were treated at the University of Iowa Hospitals and Clinics. Thirteen patients were treated with surgery alone, 15 with radiation therapy alone, one with preoperative radiation therapy and surgery, and three with surgery and postoperative radiation therapy. In(More)
PURPOSE To evaluate magnetic resonance (MR) imaging in the planning of radiation therapy for patients with cervical cancer. MATERIALS AND METHODS MR imaging was performed in 15 patients with predominantly advanced cervical carcinomas. Skin markings of the radiation ports were labeled with MR-detectable tubing and beads to assess the adequacy of port(More)
Between 1939 and 1986, 42 patients with carcinoma of the female urethra were treated with surgery and/or radiation therapy at the University of Iowa. Ten patients were treated with surgery alone, 28 with radiation therapy alone, and 4 with combined surgery and radiation therapy. Seventeen patients (40%) developed persistent or recurrent disease at the(More)
