P2-14-04: The Influence of Demographic, Psychosocial and Emotional Barriers to Screening for Colorectal and Ovarian Cancer among Latina Breast Cancer Survivors.

Background Ten percent of all new cancers are diagnosed in cancer survivors and second cancers are the sixth leading cause of cancer deaths. Breast cancer survivorship brings to the fore concern that survivors obtain thorough preventive health screening services. In two previous studies, we observed that Latina women are unable to comply with recommendations for breast cancer care due in part to psychosocial barriers including inability to understand physicians and fear of recommendations. Affective influences, particularly depression may also contribute to noncompliance via its inhibitory effect on vigilance. Here we test a hypothesis that similar barriers in addition to depression level restrict breast cancer survivor screening for colorectal and ovarian cancer. Methods We conducted a cross-sectional study of 117 Latina breast cancer survivors using self-report data. Proportions of respondents compliant and noncompliant with recommended screening protocols were compared. Reasons were coded “yes"-"no”; depression was measured with the Center for Epidemiologic Studies (CESD) instrument dichotomized at the usual cutoff of 16 points or higher signifying depression. Cancer screening compliance was determined by published NCI guidelines. Associations were determined via chi-squared analysis. Multivariate analysis was conducted using logistic regression. Results Only 5 (4.2%) of participants were screened for both cancers, 43 (36.8%) for either cancer, and 69 (59.0%) were screened for neither cancer. Reported barriers to cancer care were generally high with respect to screening for other cancers, but only “cannot understand English” (66% v 53%, p=.05) and “care is too expensive” (84% v 71%, p=.05) were associated with lack of ovarian cancer screening and none were associated significantly with lack of colorectal screening. Thirty-two percent of the sample met CESD criteria for depression, nearly twice the general population rate; it is associated with ovarian but not colorectal screening noncompliance. Factors including unemployment (74% v 57%, p=.03) and no familial history of cancer (75% v 53%, p=.02) are related to non-compliance with ovarian screening, but only unmarried status is related to colorectal screening (54% v 20%, p=.01). Separate multiple logistic regression analyses confirmed the independent significant association of these factors with ovarian and colorectal screening compliance, indicating good model fit and significant proportions of variance explained by the models. Discussion There are significant impediments to cancer screening among Latina breast cancer survivors. They derive from multiple domains (demographic factors, psychosocial barriers, and affective states). For this reason they require further research to clearly identify them. Moreover we must develop an equally broad-based preventive strategy that addresses each of these domains to promote vigilance and increase healthy behaviors among Latina women.
