Background Cervical cancer disparities persist in the predominantly Hispanic population of South Texas, and Hispanic girls are less likely to initiate and complete the three-dose HPV vaccine series. Culturally relevant interventions are needed to eliminate these disparities and improve HPV vaccine initiation and completion. Subjects We enrolled 372 Hispanic women from South Texas’ Cameron and Hidalgo counties with a daughter aged 11–17 who had not received HPV vaccine. Intervention All participants received an HPV vaccine educational brochure in their preferred language (English or Spanish) and were invited to participate in the Entre Madre e Hija (EMH) program, a culturally relevant cervical cancer prevention program. EMH participants (n= 257) received group health education, referral and navigation support from a promotora (a trained, culturally competent community health worker). Those who declined participation in EMH received the brochure only (n=115). Results Eighty-four percent of enrolled participants initiated the HPV vaccine, and no differences were observed between EMH program and brochure-only participants. Compared to brochure-only participants, EMH participants were more likely to complete the vaccine series [Adj. OR=2.24, 95% CI (1.25, 4.02)]. In addition, participants who were employed and insured had lower odds of completing the vaccine series [Adj. OR=.45, 95% CI (.21 – .96); Adj. OR=.36, 95% CI (.13 – .98), respectively]. Conclusion All enrolled participants had high vaccine initiation rates (>80%); however, EMH program participants were more likely to complete the vaccine series. HPV vaccine promotion efforts that include referral and navigation support in addition to education show promise.

Now that cancer has surpassed heart disease as the top cause of death for Hispanics in the United States, it is even more critical to focus on early detection of cancer in this population. We report the results of a theory-driven education-plus-navigation pilot intervention delivered by bilingual, bicultural community health workers (CHWs) with the goal of increasing cancer screening rates and knowledge among low-income Latinas. CHWs enrolled 691 eligible women, ages 18 to 75 years, considered rarely or never screened for breast, cervical, and colorectal cancer. Eligible women were scheduled for an education session and offered health care navigation support with appointment scheduling and reminder/follow-up calls. CHWs provided education to 535 (77%) eligible women, and arranged mammograms, Pap tests, or stool blood tests for 174 (25%) participants, with another 94 (14%) placed on a waiting list at a local health center. Statistically significant positive changes on knowledge of screening guidelines for breast, cervical, and colorectal cancer, and beliefs/attitudes regarding early detection were observed from pre- to posttest among eligible women who attended an educational session. Results highlight the effectiveness of CHW-directed interventions in recruiting individuals for programs, educating them, and influencing cancer knowledge and screening behavior.

Background: Timely diagnostic resolution of abnormal breast findings represents a critical step in efforts to reduce breast cancer morbidity and mortality. Yet, follow-up rates among resource poor populations are not optimal. Efforts to mitigate this disparity are needed. We report results of a randomized trial assessing the effectiveness of a patient support and navigation intervention in increasing timely diagnostic resolution of abnormal breast findings among indigent women.Methods: Women (n = 1,708) diagnosed with a breast abnormality at two public hospitals were randomized to an intervention or control group. The intervention, delivered through telephone, involved one call from a professional health worker and multiple calls from a lay health worker. The outcome, timely diagnostic resolution, defined as receipt of a definitive diagnosis (malignant or benign) within 6 months of the index referral, was assessed through medical chart audit.Results: Intent-to-treat analyses revealed no significant effect of the intervention on timely diagnostic resolution. Diagnostic resolution rates were 55% and 56%, respectively, in the intervention and control arms. The significant predictors were method of abnormality identification (odds ratio = 1.50) and location of first scheduled appointment (odds ratio = 0.62).Conclusions: The intervention was not effective in creating change within the County health system. Achieving optimum diagnostic follow-up may require more intensive interventions than the one tested. In addition, system-level rather than patient-level interventions may hold more promise.Impact: There are no randomized trials reported in the literature testing interventions to increase diagnostic follow-up of breast abnormalities. Future research might test patient and system-level interventions that can be sustained beyond the study period. Cancer Epidemiol Biomarkers Prev; 19(8); 1927-36. ©2010 AACR.

Background: Delayed diagnosis of breast cancer (BC) may contribute to adverse outcomes, such as reduced survival. The purpose of this study was to identify correlates of elapsed time between recognition of breast abnormalities and receipt of definitive diagnosis of BC among low-income women. Methods: Data were obtained from a cross-sectional study among a statewide sample of 921 low-income women with a new diagnosis of BC. Patients were grouped by whether their breast abnormalities were self-detected or healthcare system detected. Multivariate logistic regression analyses were used to examine associations between diagnostic delay and patient characteristics, patient communication, and system characteristics. Results: The self-detected group experienced much greater delay than the system-detected group (median intervals 80.5 vs. 31.5 days). African Americans had the longest intervals between symptom detection and diagnostic resolution; median delays in the self-detected and system-detected subgroups were 115 and 70 days, respectively, compared to 64 and 22 days for Caucasians. In multivariate analyses, African Americans had considerably greater odds of > 60-day delay than Caucasians in both the self-detected (odds ratio [OR] 3.51) and system-detected (OR 5.36) groups. Greater perceived self-efficacy in interacting with healthcare providers was significantly associated with shorter delay among the self-detected group (OR 0.86). Conclusions: Disparities in timely BC diagnosis between African Americans and Caucasians were pronounced in this uniformly low-income population of women. Women with self-detected abnormalities had markedly greater delays than those with healthcare system-detected abnormalities. Among this vulnerable group, increasing self-efficacy in interacting with healthcare providers may reduce diagnostic delays.

Background: Evidence about the accuracy of self-reports of colorectal cancer (CRC) screening is lacking. We conducted a validation protocol in a randomized trial to increase CRC screening among high-risk individuals. Methods: First-degree relatives (n = 1,280) of CRC cases who were due for CRC screening were included in the parent trial. All subjects who completed the follow-up interview (n = 948) were asked to participate in validation activities. Self-reports of receipt of CRC screening during the 12-month study period were verified via physicians. Results: Although 60% (n = 567) verbally agreed, only 171 subjects (18% of original sample) returned the signed validation form with the physician name and contact information and a medical information release statement. The signed forms were mailed to physicians with a $10 incentive and the request to list the dates of
