    Abstract:
    BACKGROUND: Early-stage breast cancer patients face a series of complex treatment decisions, with the first typically being choice of locoregional treatment. There is a need for tools to support patients in this decision-making process. METHODS: We developed an innovative, online locoregional treatment tool based on International Patient Decision Aids Standards criteria. We evaluated its impact on patient knowledge about treatment and appraisal of decision making in a pilot study using a clinical sample of newly diagnosed, breast cancer patients who were randomized to view the decision aid website first or complete a survey prior to viewing the decision aid. Differences in knowledge and decision appraisal between the two groups were compared using t-tests and chi-square tests. Computer-generated preferences for treatment were compared with patients' stated preferences using chi-square tests. RESULTS: One hundred and one newly diagnosed patients were randomized to view the website first or take a survey first. Women who viewed the website first had slightly higher, though not significantly, knowledge about surgery (p = 0.29) and reconstruction (p = 0.10) than the survey-first group. Those who viewed the website first also appraised their decision process significantly more favorably than did those who took the survey first (p < 0.05 for most decision outcomes). There was very good concordance between computer-suggested and stated treatment preferences. CONCLUSION: This pilot study suggests that an interactive decision tool shows promise for supporting early-stage breast cancer patients with complicated treatment decision making.
