ABSTRACT
The International Symposium on Intraoperative Radiation Therapy (IORT), (Toledo, OH)1 emphasized the enthusiasm for the application of this treatment to a variety of tumor types and anatomic locations. The effort, in our institution, has been primarily directed toward the following general objectives:
1. Feasibility of IORT as a combined treatment 2. Exploration of the utility of IORT in tumors of different anatomic areas 3. Assessment of patient tolerance and treatment toxicity 4. Integration of IORT into multidisciplinary treatment protocols
An analysis of 96 patients treated for a variety of tumor types and locations during the period from September 1984 to May 1986 is reported. All treatments were performed at the Clinic of the University of Navarra (CUN) in Pamplona, Spain, utilizing a Siemens® Mevatron 77 linear accelerator (electron energies — 6, 9, 12, 15, 18, or 20 meV). Computed tomography (CT)-assisted computerized dosimetry was modified and used for IORT treat ment planning. The technical details of the IORT applicators, patient transportation, and the preliminary physics data has been previously published.2
