Impact of acculturation on breast cancer treatment and survivorship care among Mexican American patients in Texas

Abstract

Purpose

Given the increasing number and diversity of cancer survivors in the USA and persistent racial/ethnic disparities in breast cancer care, we sought to examine the role of acculturation in adherence to recommended surgical treatment and survivorship care recommendations.

Methods

Study participants included 343 Mexican American women with stage I to III breast cancer who participated in the Ella Binational Breast Cancer Study and were treated at The University of Texas MD Anderson Cancer Center in Houston, Texas, between March 2007 and June 2011. Participants completed a questionnaire measuring acculturation, and clinical and demographic variables were obtained from an institutional database. Multivariable logistic regression models were constructed to examine differences in surgical procedures received and adherence to long-term survivorship care by acculturation level.

Results

Bilingual (odds ratio [OR] = 1.85; 95% confidence interval [CI] = 0.85–4.02, P = .11) and English-dominant women (OR = 2.39; 95% CI = 1.02–5.61, P = .04) were more likely to receive breast-conserving surgery (versus mastectomy) than were Spanish-dominant women. Among all patients, adherence to surveillance mammography and clinic visits decreased over time; the decline in clinic visit adherence was statistically significant (P = .005). Although no statistically significant association was found between acculturation and adherence to long-term survivorship care, receipt of breast-conserving surgery (versus mastectomy) was significantly associated with higher adherence to surveillance mammograms.

Conclusion

Acculturation may play a role in decision-making about surgical management of breast cancer, and further studies with larger samples are needed to explore its role in adherence to survivorship care recommendations. Findings from this study may help identify patients requiring additional support while making decisions pertaining to their cancer treatment and survivorship care.
