PURPOSE The radiotherapeutic management of painful bone metastases is controversial, with several institutional and national guidelines advocating use of single-fraction radiotherapy. We aimed to determine patient choice of fractionation schedule after involvement in the decision-making process by use of a decision board. PATIENTS AND METHODS Advantages and disadvantages of two fractionation schedules (24 Gy in six fractions v 8 Gy in one fraction) used in the randomized Dutch Bone Metastasis Study were discussed with patients using a decision board. Patients were asked to choose a fractionation schedule, to give reasons for their choice, and to indicate level of satisfaction with being involved in decision making. RESULTS Sixty-two patients were entered. Eighty-five percent (95% confidence interval, 74% to 93%) chose 24 Gy in six fractions over 8 Gy in one fraction (P <.0005). Variables including age, sex, performance status, tumor type, pain score, and paying class were not significantly related to patient choice. Multiple fractionation was chosen for lower re-treatment rates (92%) and fewer fractures (32%). Single-fraction treatment was chosen for cost (11%) and convenience (89%). Eighty-four percent of patients expressed positive opinions about being involved in the decision-making process. CONCLUSION Decision board instruments are feasible and acceptable in an Asian population. The vast majority of patients preferred 24 Gy fractionated radiotherapy compared with a single fraction of 8 Gy. These results indicate the need for further research in this important area and serve to remind both clinicians and national or institutional policy makers of the importance of individual patient preference in treatment decision making.

The purpose of this report is to review the complications related to different methods of anesthesia for high-dose-rate (HDR) brachytherapy for cervical carcinoma. All patients diagnosed with cervical cancer between 1999 and 2002 treated with 3-channel HDR brachytherapy were entered. Complications due to anesthesia for each fraction of brachytherapy were graded using the Common Toxicity Criteria. Eighty-four fractions of brachytherapy were delivered to 18 patients: 19 fractions with patients under general anesthesia (GA), 41 with patients under topical anesthesia and sedation, 5 with patients under paracervical nerve block, and 19 with patients under conscious sedation. Thirteen complications were reported: 12 related to GA and 1 due to paracervical nerve block. Of complications due to GA, 7 were grade 1 and 5 were grade 2. The complication due to paracervical nerve block (seizure) was grade 3. GA had significantly more complications than topical anesthesia or conscious sedation (both P < 0.001). HDR brachytherapy for cervical cancer under GA has significantly more complications than other methods. Given the increasing use of fractionated 3-channel brachytherapy, further investigation of risks and benefits of anesthetic techniques is required.
