The impact of race and language concordance between patients and navigators on time to diagnostic resolution of breast and cervical cancer screening abnormalities

BACKGROUND: Patient navigators have been shown to reduce cancer disparities among racial/ethnic minorities by improving timely diagnosis and treatment of cancer. We sought to determine if race/ethnicity and language concordance of patients and their navigator improved time to diagnostic resolution of breast and cervical cancer screening abnormalities. METHODS: Demographic data on patients and navigators from the Boston Patient Navigation Research Program were used to assess concordance by race, ethnicity, and language. Kaplan-Meier survival curves and Cox proportional hazards regression models examined the association of race/ethnicity and language concordance on time to definitive diagnosis of cancer screening abnormalities. All analyses were performed separately for breast and cervical groups. RESULTS: There were 1257 patients and 23 navigators in this study. In the breast group (n=655), 44% of patient-navigator pairs were concordant by race/ethnicity and 75% were language concordant. In the cervical group (n=602), 70% of patient-navigator pairs were race/ethnicity concordant and 87% were language concordant. There was no association with race/ethnicity concordance and time to diagnostic resolution for the breast group, aHR 1.19 (95% CI: 0.97, 1.46) or cervical group, aHR 1.23 (95% CI: 0.99, 1.53). However, in the stratified analysis, race/ethnicity concordance was associated with timelier resolution for minority women with breast and cervical cancer screening abnormalities but not for Whites. For cervical cancer screening abnormalities resolving in less than 90 days, language concordance was also associated with timelier resolution, aHR of 1.46 (95% CI: 1.18, 1.80) but there was no association in the breast group. In the subgroup analysis of Spanish concordance there was also an association of timelier resolution for those with cervical cancer screening abnormalities resolving in less than 90 days. CONCLUSION: Patient-navigator race/ethnicity concordance is associated with timelier diagnostic resolution of breast and cervical cancer screening abnormalities among minority women. Language concordance is also associated with timelier resolution in participants with cervical cancer screening abnormalities despite the availability and use of interpreters. Given poorer cancer outcomes among minority women, the use of patient navigators that are diverse by race/ethnicity and multilingual may help address barriers to care and improve health outcomes among low-income minorities

Family History of Cancer in Relation to Breast Cancer Subtypes in African American Women

Evidence on the relation of family history of cancers other than breast cancer to breast cancer risk is conflicting and most studies have not assessed specific breast cancer subtypes

Triple-negative breast cancers are increased in black women regardless of age or body mass index

INTRODUCTION. We investigated clinical and pathologic features of breast cancers (BC) in an unselected series of patients diagnosed in a tertiary care hospital serving a diverse population. We focused on triple-negative (Tneg) tumours (oestrogen receptor (ER), progesterone receptor (PR) and HER2 negative), which are associated with poor prognosis. METHODS. We identified female patients with invasive BC diagnosed between 1998 and 2006, with data available on tumor grade, stage, ER, PR and HER2 status, and patient age, body mass index (BMI) and self-identified racial/ethnic group. We determined associations between patient and tumour characteristics using contingency tables and multivariate logistic regression. RESULTS. 415 cases were identified. Patients were racially and ethnically diverse (born in 44 countries, 36% white, 43% black, 10% Hispanic and 11% other). 47% were obese (BMI > 30 kg/m2). 72% of tumours were ER+ and/or PR+, 20% were Tneg and 13% were HER2+. The odds of having a Tneg tumour were 3-fold higher (95% CI 1.6, 5.5; p = 0.0001) in black compared with white women. Tneg tumours were equally common in black women diagnosed before and after age 50 (31% vs 29%; p = NS), and who were obese and non-obese (29% vs 31%; p = NS). Considering all patients, as BMI increased, the proportion of Tneg tumours decreased (p = 0.08). CONCLUSIONS. Black women of diverse background have 3-fold more Tneg tumours than non-black women, regardless of age and BMI. Other factors must determine tumour subtype. The higher prevalence of Tneg tumours in black women in all age and weight categories likely contributes to black women's unfavorable breast cancer prognosis.LaPann Fund; Research Enhancement Fun

Feasibility and Acceptability of Mindfulness-Based Group Visits for Smoking Cessation in Low-Socioeconomic Status and Minority Smokers with Cancer

Objective: Smoking cessation studies tailored for low-income and racial/ethnic minority cancer patients are limited. African American and low-socioeconomic status (SES) smokers have higher cancer mortality rates and are less likely to use evidence-based smoking cessation treatments compared with white and higher SES counterparts. Mindfulness training is a promising approach to address racial and SES disparities in smoking cessation. The authors assessed the feasibility and acceptability of a mindfulness-based smoking cessation (MBSC) medical group visit for low-income and racially diverse smokers with cancer. Design and intervention: The authors adapted the integrative medical group visit model used for chronic pain and included the You Can Quit smoking cessation curriculum used at the study site, Tobacco Treatment Center. The program was conducted in eight weekly 2-h visits. The authors then tested the feasibility and acceptability of this intervention for actively smoking cancer patients and cancer survivors in two pilot groups (N = 18) using a pre-post design. Setting/Location: This study took place at Boston Medical Center, a large urban safety net academic teaching hospital. Outcome measures: The authors used a medical group visit intake form to collect data on weekly cigarette intake and home practice. They also gathered additional qualitative data from focus groups and in-depth interviews. Results: Over 50% of participants (n = 10) self-identified as black and 56% reported an annual income of $20,000 or less. Over two-thirds of the participants attended four or more of the eight group visits. There was a significant decrease in weekly cigarette intake from 75.1 cigarettes at baseline to 44.3 at 3 months (p = 0.039). None of the participants quit smoking. Participants were satisfied with the program and reported positive lifestyle changes. Conclusion: MBSC group visits are feasible and acceptable among racially diverse and low-SES smokers with cancer and should be further studied in a larger cohort

Family History of Cancer in Relation to Breast Cancer Subtypes in African American Women

BACKGROUND: Evidence on the relation of family history of cancers other than breast cancer to breast cancer risk is conflicting and most studies have not assessed specific breast cancer subtypes. METHODS: We assessed the relation of first degree family history of breast, prostate, lung, colorectal, ovarian, cervical cancer, and lymphoma or leukemia, to risk of estrogen receptor positive (ER+), ER−, and triple negative breast cancer in data from the African American Breast Cancer Epidemiology and Risk Consortium. Multivariable logistic regression models were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: There were 3,023 ER+ and 1,497 ER− breast cancer cases (including 696 triple negative cases) and 17,420 controls. First degree family history of breast cancer was associated with increased risk of each subtype: OR=1.76 (95% CI 1.57–1.97) for ER+, 1.67 (1.42–1.95) for ER−, and 1.72 (1.38–2.13) for triple negative breast cancer. Family history of cervical cancer was associated with increased risk of ER− (OR=2.39, 95% CI 1.36–4.20), but not ER+ cancer. Family history of both breast and prostate cancer was associated with increased risk of ER+ (3.40, 2.42–4.79) and ER− (2.09, 1.21–3.63) cancer, but family history of both breast and lung cancer was associated only with ER− cancer (2.11, 1.29–3.46). CONCLUSIONS: A family history of cancers other than breast may influence risk of breast cancer and associations may differ by subtype. IMPACT: Greater surveillance and counseling for additional screening may be warranted for women with a family history of cancer
