Patient and physician decision styles and breast cancer chemotherapy use in older women: Cancer and Leukemia Group B protocol 369901.

ABSTRACT: PURPOSE Physician and patient decision styles may influence breast cancer care for patients ≥ 65 years ("older") because there is uncertainty about chemotherapy benefits in this group. We evaluate associations between decision-making styles and actual treatment. METHODS Data were collected from women treated outside of clinical trials for newly diagnosed stage I to III breast cancer (83% response) from January 2004 through April 2011 in 75 cooperative group sites. Physicians completed a one-time mailed survey (91% response), and clinical data were abstracted from charts. Patient decision style was measured on a five-point scale. Oncologists' preference for prescribing chemotherapy was based on standardized vignettes. Regression and multiple imputation were used to assess associations bet
