578 Background: Advances in radiotherapy allow the ability to deliver ablative treatments without compromising outcomes, but there has been limited application of these treatments to early-stage breast cancers. The purpose of this study was to explore patients’ interest in pursuing nonsurgical treatment approaches for their early-stage breast cancer. Methods: Investigators conducted a qualitative descriptive study involving semi-structured interviews with 21 early-stage breast cancer patients eligible for participation in a phase 2 trial offering omission of surgery. Interviews were transcribed, and three independent reviewers performed an inductive, thematic analysis to generate themes and subthemes. Results: Data analysis revealed the following factors that impacted patients’ willingness and desire to explore nonsurgical treatment options: Perceptions and feelings about their cancer; Current quality of life and the level of support available in their daily life; External conversations focusing on family members’ and friends’ experiences with cancer and/or cancer treatments; Personal healthcare experiences, including with their current breast cancer diagnosis; Perceptions and feelings about their physicians; Conversations with their physicians about their treatment options; and Self-identified desire to direct care decisions. Specifically, patients described fearing surgery and surgical recovery and wanting to avoid negative surgery-related events previously experienced by friends, family, and themselves. Participants also expressed a desire to preserve their breast(s), receive treatment per the latest research, match the level of treatment with the severity of their cancer, and avoid other comorbidities as reasons for omitting surgery. Patient reasons for pursuing surgery included the desire to remove their cancer immediately, prior positive experiences of friends, family, and themselves with surgery, lack of concern about preserving their breast(s), and prior negative experiences of friends, family, and themselves with radiation. Conclusions: The results of this study highlight that there is patient interest in nonsurgical options for biologically favorable early stage breast cancers. A key factor hindering patient education and awareness of nonsurgical options is how the physician frames the discussion and presents treatment options. In addition, patients’ self-identity and the prior experiences of friends, family, and self with cancer treatment and surgery in general appear to be key factors in their decision-making. The findings from this study demonstrate an unmet need to explore nonsurgical options for early-stage breast cancer. Study results can help shape conversations around shared decision making and clinical trial design and result in more personalized treatment options for women with early-stage breast cancer.
