Breast Cancer Mode of Detection in a Population-Based Cohort.

OBJECTIVE: To evaluate how breast cancers come to clinical attention (mode of detection [MOD]) in a population-based cohort, determine the relative frequency of different MODs, and characterize patient and tumor characteristics associated with MOD. PATIENTS AND METHODS: We used the Rochester Epidemiology Project to identify women ages 40 to 75 years with a first-time diagnosis of breast cancer from May 9, 2017, to May 9, 2019 (n=500) in a 9-county region in Minnesota. We conducted a retrospective medical record review to ascertain the relative frequency of MODs, evaluating differences between screening mammography vs all other MODs by breast density and cancer characteristics. Multiple logistic regression was conducted to examine the likelihood of MOD for breast density and stage of disease. RESULTS: In our population-based cohort, 162 of 500 breast cancers (32.4%) were detected by MODs other than screening mammography, including 124 (24.8%) self-detected cancers. Compared with women with mammography-detected cancers, those with MODs other than screening mammography were more frequently younger than 50 years of age (P=.004) and had higher-grade tumors (P=.007), higher number of positive lymph nodes (P<.001), and larger tumor size (P<.001). Relative to women with mammography-detected cancers, those with MODs other than screening mammography were more likely to have dense breasts (odds ratio, 1.87; 95% CI, 1.20 to 2.92; P=.006) and advanced cancer at diagnosis (odds ratio, 3.58; 95% CI, 2.29 to 5.58; P<.001). CONCLUSION: One-third of all breast cancers in this population were detected by MODs other than screening mammography. Increased likelihood of nonmammographic MODs was observed among women with dense breasts and advanced cancer.

The Interplay Between Group Identity, Suicidality, and Bullying in Midwestern Middle School Youth, 18-42.

Bullying peaks in middle school and is a risk factor for negative mental health outcomes, including suicidality. Suicide rates are higher in nonmetropolitan/rural areas and for American Indian/Alaska Natives compared to other racial/ethnic groups. Stigma-related bullying, a type of interpersonal discrimination, is increasingly considered an important driver of peer victimization. This study centers on the group identity characteristics of race/ethnicity, weight status, and sex to explore how school-based and electronic-bullying victimization mediate suicidality amongst a cohort of middle school students in North Dakota. Bivariate, multivariate, and structural equation modeling were performed using data from the 2015 North Dakota Middle School Youth Risk Behavior Survey. Minoritized race/ethnicity, very overweight, and female students all experienced statistically higher suicidality than comparison groups, mediated in some instances by bullying. Group identity, stigma, and discrimination may influence suicidality in North Dakota middle school youth. More information is needed on stigma and discrimination, including intersections of identity, as drivers of bullying and suicidality in minoritized youth in nonmetropolitan/rural areas.

Perspectives regarding family disclosure of genetic research results in three racial and ethnic minority populations.

The lack of data on perspectives of racial and ethnic minority populations regarding family disclosure of individual research results (IRR) hinders the development of return of IRR policies and practices that are meaningful and culturally appropriate in diverse populations. This research aims to uncover preferences regarding family disclosure of IRR and identify factors that may shape the preferences in three minority populations. Nine focus groups with 68 adult African American, Hispanic/Latinx, and American Indian/Alaska Native individuals were conducted. Data were analyzed using thematic analysis. Participants were willing to share IRR with relatives who elected to know and preferred a participant-driven (vs. researcher-driven) decision-making process. Privacy of personal information was deemed important, as were anticipated familial benefits from genetic information, except when improper use of the information was suspected. Factors influencing family disclosure decisions included the family's biological and emotional closeness, and participants' perceived mental preparedness of the relative. Family disclosure of IRR among racial and ethnic minority individuals is a complex decision-making process wherein issues of individual privacy are entangled with family dynamic and familial benefit considerations. These data suggest that policies surrounding family disclosure of IRR should carefully consider participant preferences and adopt a participant-driven approach.
