Purpose:
To determine the proportion of patients undergoing palliative radiotherapy (RT) for bone pain who would like to participate in the decision-making process, and to determine their choice of palliative RT regimen (2000 cGy in five fractions vs. 800 cGy in one fraction) for painful bone metastases.
Methods And Materials:
Eligible patients were approached and all patients agreeing to participate provided written informed consent. Patients' decisional preferences were studied using a five-statement preference instrument. A decision board was used to help patients decide their preferred palliative RT regimen. Factors influencing patients' choices were studied using a visual analog scale.
Results:
A total of 101 patients were enrolled in the study (55 women and 46 men). The preferences for decision-making were as follows: 30 active, 47 collaborative, and 24 passive. Most (55 [76%] of 72) patients favored one fraction of palliative RT (95% confidence interval, 65-86%). Patients were more likely to select the 800 cGy in one fraction because of the convenience of the treatment plan (odds ratio, 1.024; 95% confidence interval, 1.004-1044) but were less likely to choose it because of the chance of bone fracture (odds ratio, 0.973; 95% confidence interval, 0.947-1.000) compared with 2000 cGy in five fractions.
Conclusion:
Most participating patients preferred to decide either by themselves or with the radiation oncologists which treatment option they preferred. An 800-cGy-in-one-fraction regimen was favored, independent of the treated site. The convenience of the treatment plan and the likelihood of bone fracture were the most important factors influencing patients' choice.
