  • A survey was conducted in Latin America to evaluate the clinical aspects of quality assurance in radiotherapy. A questionnaire was prepared and sent to 46 institutions. Twenty-seven centers (58.5%), from nine countries, answered the questionnaire. The study was divided into three topics: a) patient-related statistics; b) staffing and education; and c) equipment and facilities. Radiotherapy training programs are available in only 37% of the centers studied. A large number of megavoltage units are old, operating at a shorter than optimum distance with sources of very low activity. The number of high energy linear accelerators is unsatisfactory. Problems in treatment planningmore » facilities were also identified. Regionalization of radiation therapy services is recommended as a possible way to improve quality at a reasonable cost.« less
  • The present status of the quality assurance work regarding the physical aspects in radiation treatment is discussed. In particular, the situation in Europe is surveyed. An analysis of the errors in the delivered absorbed dose to a specified point in the irradiated patient shows that the uncertainty, to approximately the same degree, depends on the dose distribution determination, the dose planning and the patient irradiation. Following the procedure generally in use, the overall uncertainty will be about 8%. The random uncertainties are estimated as one standard deviation and non-random uncertainties to corresponding degree of uncertainty. It is argued that thismore » level must be improved. Furthermore, dose intercomparisons show that in reality much larger errors occur in clinical practice. Different means to improve the situation are discussed.« less
  • Quality assurance in radiotherapy is performed in different ways in Argentina than in other countries. A part of this program is carried out by the Secondary Standard Dosimetry Laboratory (SSDL-WHO/IAEA), which is a part of the Atomic Energy Commission. This laboratory organizes TLD postal intercomparison; calibrates and checks radiotherapy units and dosimeters; gives education in the physics of radiotherapy; has collaborated in the production of rules for the operation of radiation therapy units and maintains the application of these rules. A description of the activities of the SSDL and a brief explanation about the other activities, the present situation andmore » future plans are discussed.« less
  • A high standard of radiotherapeutic practice must be sought in all phases of management of a patient with malignant disease. Radiation therapy must be appropriately chosen and integrated with surgery, cytotoxic chemotherapy and all other modes of treatment. The most suitable technique with a dose, fractionation and time regime must devised and executed with technical and personal care. Follow-up to truly assess tumor control and morbidity is essential so as to guide the management of future patients. To achieve this in Europe great reliance is placed upon the training and qualification of the therapist and staff. High standards are appliedmore » to the professional qualifications for radiation physicists, nurses and technical staff. In the countries belonging to the European economic union, a new Diploma in Radiation Therapy has been established to be a standard for consultant practice through all the countries included. The European Organization for Research and Treatment of Cancer has recently initiated a quality control study in some of the centers included in the Radiotherapy Group. A preliminary report has just appeared on the results of the clinical and dosimetric studies in 8 centers placed in 5 European countries.« less
  • Efforts to develop a Quality Assurance Program at the Joint Center for Radiation Therapy are described. This includes defining the clinically relevant considerations, describing acceptable goals and allowable variation, developing mechanisms for determining compliance with these goals, and educational approaches toward common understanding. Consideration toward the development of regional and national Quality Assessment Programs are discussed concerning auditing techniques, developing a satisfactory reporting format, and creating a worthwhile learning experience for all involved.
