OBJECTIVE: To investigate the information provision concerning possible benefits and harms of short-course preoperative radiotherapy (PRT) at pre-treatment consultations between radiation oncologists and @entity5 @entity1 . DESIGN: Observational study. METHOD: We audiotaped the consultations between 17 radiation oncologists and 81 @entity1 with primary @entity5 who were eligible for PRT. The recordings were transcribed and analysed descriptively. RESULTS: A median of seven benefits/harms of PRT were addressed at each consultation (range, 2-13). This number differed both in and between individual oncologists and was not consistently associated with the @entity1 's characteristics. A total of 30 different treatment outcomes was addressed. The effect of PRT on local control was addressed in all consultations, and the effect on survival in 16%. The most important adverse effects according to the literature are @entity29 and @entity250 . These were addressed in 82% and 85% of consultations, respectively; sexual problems were discussed significantly more often with male than female @entity1 . Four out of five @entity1 did not initiate discussion on potential benefits/harms. CONCLUSION: There was a considerable variation in the number and nature of benefits and harms of PRT that were discussed prior to treatment. This variation indicates a lack of clarity concerning which benefits/harms of radiotherapy should be discussed with newly-diagnosed @entity1 . This suboptimal provision of information to @entity1 hampers the process of shared decision making, in which the decision is based on each individual @entity1 's weighing of benefits and harms. We do not believe our findings to be specific for PRT, but expect to find similar variation in provision of information with regard to other treatment decisions.
