Exploring and supporting older women’s chemotherapy decision-making in early-stage breast cancer.
181 Background: Few studies have focused on the therapeutic decision-making process in older adults with cancer. This study sought to address this gap by exploring older adult breast cancer patients’ (pts) perspectives on neo/adjuvant chemotherapy, thereby identifying informational needs as they navigate the decision-making process. Methods: Women ≥65 years diagnosed with early stage (I-III) breast cancer were recruited from an academic center following their decision on whether to receive neo/adjuvant chemotherapy. Pts took part in individual semi-structured interviews to explore their perspectives, knowledge, and values. They also completed surveys assessing sociodemographics, health literacy/numeracy, and shared decision-making (SDM-Q-9). Interviews were audio-recorded and transcribed, and analyzed using the Sort and Sift, Think and Shift qualitative approach. Quantitative data was summarized using descriptive statistics. Results: 26 pts completed interviews (age range 65-92; 81% non-Hispanic White; 81% ≥ college degree; 70% single). 14 pts elected to undergo chemotherapy and 11 declined. Most pts had adequate health literacy (mean = 4.31; SD = 1.1 on Single Item Literacy Scale) and numeracy (mean = 4.4; SD = 1.0 on Single Item Numeracy Scale). Pts scored high on the shared decision-making questionnaires (SDM-Q-9, mean = 5.3, SD = 0.7). Thematic analysis uncovered several commonalities regardless of the decision. Pts sought information regarding their disease/treatment, but in some instances were confused regarding the objective of chemotherapy. They often chose treatment outside of the physician’s recommendation, and referenced the subjective experience of friends/family members with cancer. Self-perception of health and the side-effects of chemotherapy were also key factors. Pts also placed importance on the maintenance of quality of life throughout the treatment trajectory. Conclusions: Decision-making strategies in older patients were shaped by knowledge, values and the anectodal experience of others. These discussions will subsequently shape the creation of a decision support tool for older pts and physicians to better facilitate the shared-decision making process.
