Interstitial brachytherapy: past-present-future.

Abstract

This article summarizes and reviews the development of brachytherapy from 1930 to 1990. Its purpose is to highlight the immense contribution made to its underlying science and clinical practice by Dr. Frank Ellis, who has been personally involved with it, in theory and in practice, for that whole half-century. A remarkable achievement in itself, but so much the more when it is seen beside his contributions to other aspects of radiation in the service of man. The early use of solid sources leads on to a discussion of manual afterloading and iridium. This leads on to a quick survey of the development of dosimetry. Thereafter clinical indications are briefly discussed and some published results tabulated. Lastly, some pointers to possible future development and benefits are discussed. Mention is also made of some continuing unresolved problems where new work could help to establish the most appropriate use of brachytherapy.
