The role of radiotherapy in the treatment of cancer is expanding. The development of new technology and sophisticated techniques of high precision allows better local control, with the delivery of high doses to the target, while sparing normal tissues. The clinical implementation of ionizing radiation demands the co-operation of specialized professionals (radiation oncologists, physicists, radiation technologist etc) who are responsible for the provision of effective, safe and high-quality care. The aim of a quality assurance program in radiotherapy is to provide the best available care to the patients, in a systematic way. There are three aspects of quality in radiotherapy: firstly, the clinical aspect, regarding resources (personnel and equipment), procedures (treatment, follow-up), outcome (tumor control, toxicity), secondly, the physical aspect which involves the control of the equipment parameters so as to achieve the desirable biologic effects of radiation, and, thirdly, the technical aspect, which involves the accuracy of treatment delivery. Besides the international guidelines for the diagnosis and treatment of cancer, there is the need of a quality management system that provides the tools for resource allocation and continuous improvement of patient-centered health services, in a demanding and competitive environment. So quality in not achieved by chance, it's the result of serious effort, motivation and vision. It is a wise choice among alternatives. The concept of quality is dynamic and the target needs to be re-evaluated and updated, constantly. It is a matter of specialized personnel, continuous education and teamwork, under the co-ordination of talented leaders. This paper addresses the importance and the implementation of quality assurance in radiation oncology through a literature review.
