Patient participation in treatment decision making and the psychological consequences of breast cancer surgery.

Women in the early stages of breast cancer can be treated effectively with either modified radical mastectomy or tumor excision plus postoperative radiation therapy. Thus, breast cancer patients may be given a choice between these two modes of treatment. In some states, physician disclosure of such treatment alternatives for breast cancer is mandated by law. Despite the belief that patient participation in decision making is beneficial, the evidence is preliminary, although generally supportive. This study examined the extent to which patient participation in the choice of surgical options was related to psychological functioning, fear of cancer recurrence, and aspects of treatment satisfaction 3 and 13 months postoperatively. Few associations with degree of participation in treatment decision making or type of surgical treatment emerged after 3 months. After 13 months, however, women with greater levels of input into their treatment plan were more satisfied with their medical care, although they were not better off in terms of psychological functioning or fear of cancer recurrence. The positive effects of shared treatment decision making may be more closely related to aspects of longer term treatment satisfaction rather than a buffer against psychological distress resulting from breast cancer.
