Method of presenting oncology treatment outcomes influences patient treatment decision-making in metastatic colorectal cancer.

Background: The methods used to communicate relevant outcomes in oncology to patients will likely influence treatment decisions. The purpose of this study was to examine the influence of three different methods of describing the efficacy of therapy on treatment decisions regarding management of metastatic colorectal cancer.

Methods: Participants reviewed a clinical scenario and randomly received one of three ways of describing efficacy of chemotherapy in metastatic colorectal cancer: (1) relative risk reduction, (2) tumor response rate, and (3) median overall survival.

Preferences for different methods of communicating information regarding adjuvant chemotherapy for breast cancer.

Many patients play an active role in determining their cancer treatments, and the communication of medical information influences patient decision-making. This study examined participants' preferences between various methods of communicating quantitative risks and benefits of adjuvant chemotherapy. Using clinical vignettes, participants were first asked to decide whether or not to endorse chemotherapy and were subsequently asked about their preferences for the methods used to communicate the risks and benefits.
