Factors affecting patients' perceptions of choice regarding adjuvant chemotherapy for breast cancer.

INTRODUCTION: Patients' perceptions of having had freedom of choice in treatment decision-making are shown to have implications for their quality of life. It is, therefore, important to determine what factors underlie these perceptions. One factor that has been studied is whether or not patients believed that their doctor had offered choice of treatment. However, even when choice is actually offered, patients may still feel that they have no choice. Little attention has been paid to other factors that may contribute to patients' perceptions of having had no choice. Our purpose was to explore (1) whether early-stage breast cancer patients perceived to have had a choice with regard to adjuvant chemotherapy, and (2) their reasons for having perceived no choice. PATIENTS AND METHODS: The determinants of no choice that we examined were: (1) (preferred) involvement in treatment decision-making, (2) perceived clinical benefits of chemotherapy (e.g., cure), (3) perceived psychological benefits (e.g., less worries), and (4) perception of being able to cope with the side effects. All predictors, as well as patient and clinical characteristics, were entered simultaneously in a multiple logistic regression analysis and non-significant predictors were removed step-by-step, until only significant predictors (p<0.05) remained. Because determinants may differ between patients with experience of chemotherapy and those without, both treatment groups were analyzed separately.
RESULTS: Four hundred and forty-six patients filled out the questionnaire (62%). Sixty-six percent of patients who had been treated with chemotherapy and 86% of inexperienced patients had perceived no treatment choice. In both treatment groups, patients who preferred a shared role or a passive role in treatment decision-making were statistically significantly more likely to have perceived no treatment choice than patients who preferred an active role. Surprisingly, beliefs about the clinical and psychological benefits of chemotherapy did not influence patients' perceptions of having had choice of treatment.
CONCLUSION: If we adhere to patient autonomy and shared decision making, we may consider the perception of no treatment choice as a negative outcome of treatment decision-making. However, if this is the result of the patients' preference for less active involvement in treatment decision-making, the topic of perception of no treatment choice may be viewed in a different light.
