Decisional Preferences And Satisfaction With Short-Course Radiation For Breast Cancer.

193Background: Limited literature exists regarding preferences and decisional satisfaction for women who choose accelerated partial breast irradiation (APBI) in lieu of 6-7 weeks of radiation. This analysis provides long-term patient reported outcomes in women treated with APBI at one institution. Methods: Records of women treated primarily with balloon-based APBI (2005-2013) were reviewed after IRB approval. Women with recurrent disease or poor prognosis second primary cancer were excluded. Assessment of decisional factors important to the patient, as well as satisfaction and regret with treatment choices (Decisional Regret and Satisfaction Scales) were captured via mail or telephone. Results: In 141 women who met inclusion criteria, 83 participated. Median age at diagnosis was 62 years (SD = 9), and median time from RT to survey completion was 102 months (SD = 8). Histology was pre-invasive, (25%), invasive (52%), and combined invasive/pre-invasive (23%). The majority had estrogen/progesterone receptor ...
