The authors presents a clinical case treated with brachytherapy performed w
ith special mold of gold-198 disc, with the purpose of evaluating the distr
ibution of radiation dose, the viability of manufacturing the radioactivity
prosthesis and its operational cost. In despite of being only one case, we
can conclude that the prosthesis with gold-198 foils can be manufactured i
n acrylic with thickness thinner than those ones with cylinder of cesium-13
7, resulting lower operational costs, besides permitting better distributio
n of radiation dose on the lesion. (C) 1999 Elsevier Science Ltd. All right
