Treatment-related symptoms among underserved women with breast cancer: the impact of physician-patient communication.

Low-income, minority women are more likely to be undertreated for breast cancer (BC) treatment-related symptoms than whites. This study assessed the impact of patient-physician communication on symptom resolution. A cross-sectional, California statewide survey was conducted among 921 low-income women with BC. Ethnic/racial differences in BC treatment-related symptoms (pain, nausea/vomiting, depression) reporting and physician' awareness of these symptoms were assessed by patient report. Multivariate logistic regression models were used to investigate the impact of patient-physician communication on symptom resolution. Depression was the most common symptom reported by patients (66%), yet physicians were the least aware of it (26.3%), especially among less-acculturated Latinas (18.9%) and Asian/Pacific Islanders (14%; P < 0.001). Greater patient-perceived self-efficacy in communication with physicians and greater physician awareness of the symptom positively predicted pain resolution, controlling for sociodemographic variables, comorbidity, and treatment received (AOR = 1.05, P < 0.0001; AOR = 6.12, P < 0.001). Physician awareness was a significant determinant of depression resolution (AOR = 13.46, P < 0.001). Yet patient-perceived self-efficacy played a much more important role than physicians' awareness in nausea resolution (AOR = 1.04, P = 0.0002). Less-acculturated Latinas tended to achieve less symptom resolution than whites, while this negative impact disappeared or was moderated after patient-physician communication was considered. This study suggests that physicians under-recognized depression, especially among Latinas. The resolution of BC treatment-related symptoms can be addressed by appropriate educational interventions targeted at patient-physician communication. Effective patient-physician communication can moderate disparities in symptom resolution among Latinas, regardless of language acculturation.
