PURPOSE: A retrospective analysis for patients with oropharyngeal carcinoma who were treated with radiation was performed to assess the results of treatment and patterns of failure, and to identify the factors that might influence survival. METHODS AND MATERIALS: From March 1985 through June 1993, 53 patients with oropharyngeal carcinoma were treated with either radiation therapy alone or combination of neoadjuvant chemotherapy...

PURPOSE: To improve treatment modality and results by analysis of clinical characteristics. local control, survival and resurrence rate in limited stage small cell lung cancer. METHODS AND MATERIALS : 26 patients with limited stage small cell lung cancer were treated with combined radiation and chemotherapy from Feb. 1986 to Dec. 1992 at the National Medical Center. We followed up on 21...

PURPOSE: To improve the treatment results of locally advanced nonsmallcell lung cancer (NSCLC) patient, we treated those paients with regional hyperthermia combined with radiotherapy. And we conducted a retrospective analysis of the results. METHODS AND MATERIALS: Thirty two nonsmall cell lung cancer patients treated at the Department of Radiation Oncology, St. Mary's hospital. Catholic University Medical College were the base of...

PURPOSE: This is a retrospective study to compare the palliation rates, survival rates and complications of low dose rate and high dose rate endobronchial brachytherapy in the management of malignant airway obstruction. METHODS AND MATERIALS: Forty three consecutive patients with malignant airway compromise from primary or metastatic lung tumors were treated with low dose rate(LDR) endobronchial Iridium-192 insertion (21 patients) between...

PURPOSE: To evaluate the effectiveness and tolerance of patients ofexternal beam radiotherapy ofr carcinoma of the extrahepatic biliary system (EHBS) including gall bladder (GB) and extrahepatic bile ducts (EHBD) and to define the role of radiotherapy for these tumors. METHODS AND MATERIALS: We retrospectively analyzed the records of 43 patients with carcinoma of the EHBS treated with external beam radiotherapy at...

PURPOSE: This report is the result of retrospective analysis for children who received prophyactic cranial irradiation combined with intrathecal chemotherapy. METHODS AND MATERIALS: Ninety children with ALL who had got bone marrow remission after induction chemotherapy received PCI. All but 3 children were treated with a dose of 1800 cGy as a standard regimen. While the PCI was given, all patients...

PURPOSE: To get an acute steepness of dose gradients at outside the target volume in intracranial lesion and a less limitation of beam selection avoiding the high dose at normal brain tissue, this Photon Knife Radiosurgery System was developed in order to provide the three-dimensional dose distribution through the reconstruction of CT scan and the combined stereotactic tranmultiarc beam mode...

PURPOSE: This analysis was to evaluate the radiation dose around a tracheostoma and spinal cord in the case of advanced laryngeal cancers in which a total laryngectomy was done before radiotherapy. METHODS AND MATERIALS: The radiation dose around a tracheostoma and spinal cord was measured by thermoluminescence and film dosimety in the phantom. Radiotherapy treatment planning was done in 12 cases of...
