6544 Background: Although increasing informed decision making has been identified as a mechanism for reducing disparities in breast cancer treatment outcomes, little is known about these issues from the Latina perspective. Methods: 2,030 women with non- metastatic breast cancer diagnosed from 8/05–5/06 and reported to the Los Angeles County SEER registry were identified and mailed a survey shortly after receipt of surgical treatment. Latina and African American women were over-sampled. Survey data were merged to SEER clinical data. We report results on a 50% respondent sample (N=742) which will be updated based on a final respondent sample of 1,400 patients (projected response rate, 72%). Dependent variables were patient reports of how decisions were made (doctor-based, shared, patient-based); their preferred amount of decisional involvement; and two 5-item scales measuring satisfaction with decision-making and decisional regret. Results: 32% of women were white, 28% African American (AA), 20% Latina-English speaking (L-E), and 20% Latina-Spanish speaking (L- SP). About 28% of women in each ethnic group reported a surgeon-based, 33% a shared, and 38% a patient-based surgical treatment decision. L- SP women reported wanting more involvement in decision making more often than white, AA or L-E women (16% vs. 4%, 5%, 5%, respectively, p<0.001). All minority groups were less likely than white women to have high decisional satisfaction with L-SP women having the lowest satisfaction (w-74%, AA-63%, L-E-56%, L-SP-31%, p<0.001). L-SP women were more likely than white, AA or L-E women to have decisional regret (35% vs. 7%, 15%, 16%, respectively, p<0.001). Multivariate regression showed that Latina ethnicity and low literacy were independently associated with both low decisional satisfaction and high decisional regret (p<0.001). Conclusions: Latina women, especially Spanish speakers, report more dissatisfaction with the breast cancer surgical treatment decision-making process than other racial/ethnic groups. These results highlight the challenges to improving breast cancer treatment informed decision making for Latina women. Future interventions to improve satisfaction with the decision process should be tailored to ethnicity and acculturation. No significant financial relationships to disclose.
